Fracture-related infections: a comprehensive review of diagnosis and prevention: HoeJeong Chung, Hoon-Sang Sohn; J Musculoskelet Trauma 2025;38(2):86-95. Published online April 25, 2025; DOI: https://doi.org/10.12671/jmt.2025.00164

Abstract PDF: Fracture-related infections are challenging complications in orthopedic trauma that often require prolonged treatment and impose a significant healthcare burden. Accurate diagnosis and effective prevention strategies are essential for minimizing their occurrence. A recent international consensus has established standardized diagnostic criteria based on clinical, microbiological, radiological, and histopathological findings. Prevention is the top priority and involves a thorough preoperative risk assessment, along with glycemic control, nutritional optimization, and management of comorbidities, as well as intraoperative and postoperative measures such as appropriate antibiotic prophylaxis, surgical site antisepsis, and meticulous wound care. A multidisciplinary approach involving orthopedic surgeons, infectious disease specialists, and microbiologists is crucial for successfully reducing the burden of fracture-related infections.

Reverse V step-cut osteotomy for the correction of cubitus varus in adults: a retrospective study: Jinyoung Bang, Hyung Jun Koo; J Musculoskelet Trauma 2025;38(2):102-108. Published online April 25, 2025; DOI: https://doi.org/10.12671/jmt.2025.00045

Abstract PDF: Background
Cubitus varus deformity in adults most commonly occurs as a late complication resulting from malunion of distal humeral fractures sustained during childhood. This deformity can cause cosmetic problems and anatomical deformities that hinder normal sports activities and potentially lead to long-term complications. Although various surgical techniques exist for correcting cubitus varus, this study investigated the clinical and functional outcomes of reverse V step-cut osteotomy.
Methods
In total, 15 patients underwent surgical treatment with reverse V step-cut osteotomy between 2012 and 2023. The mean age of the patients at the time of surgery was 46.3 years (range, 20–65 years). The preoperative carrying angle was ‒11.09° of varus, which was corrected to +12.81° of valgus postoperatively. The mean preoperative lateral prominence index (LPI) was ‒10.03, and the mean postoperative LPI improved to ‒4.48. A comparison to the unaffected side showed a P-value of 0.978, indicating similarity.
Results
Preoperatively, eight patients exhibited signs of posterolateral rotatory instability, and among them, three underwent concomitant lateral ulnar collateral ligament reconstruction. Seven patients reported ulnar nerve symptoms, and all underwent concurrent ulnar nerve release. Postoperatively, improvements in elbow pain, instability, and ulnar nerve symptoms were observed. One patient required reoperation due to malunion and insufficient correction, but no other complications were noted.
Conclusions
These outcomes demonstrate that reverse V step-cut osteotomy can be an effective treatment method for cubitus varus deformity in adults. Level of evidence: IV.

Treatment of avulsion fractures around the knee: Jeong-Hyun Koh, Hyung Keun Song, Won-Tae Cho, Seungyeob Sakong, Sumin Lim; J Musculoskelet Trauma 2025;38(2):63-73. Published online March 31, 2025; DOI: https://doi.org/10.12671/jmt.2025.00073

Abstract PDF: Avulsion fractures of the knee occur when tensile forces cause a bone fragment to separate at the site of soft tissue attachment. These injuries, which frequently affect adolescent athletes, can involve the cruciate and collateral ligaments, arcuate complex, iliotibial band, and patellar and quadriceps tendons. Radiographs aid in the initial diagnosis, while computed tomography and magnetic resonance imaging facilitate a comprehensive evaluation of injury severity and concomitant damage. Specific avulsion fracture types include: anterior cruciate ligament avulsions (tibial site, Meyers and McKeever classification), posterior cruciate ligament avulsions (tibial attachment, Griffith's classification), Segond fractures (anterolateral complex injury), iliotibial band avulsions, medial collateral ligament avulsions (reverse Segond, Stieda fractures), arcuate complex avulsions ("arcuate sign"), medial patellofemoral avulsions (patellar dislocations), and patellar/quadriceps tendon avulsions. The treatment depends on the fracture location, displacement, and associated injuries. Non-displaced fractures can be managed conservatively, while displaced fractures or those with instability require surgical reduction and fixation. Prompt recognition and appropriate intervention prevent complications such as deformity, nonunion, malunion, and residual instability. This review provides an overview of the pathogenesis, diagnosis, and management of knee avulsion fractures to guide clinical decision-making.

Avulsion fractures around the hip joint and pelvis: Won-Sik Choy, Yonghan Cha, Jung-Taek Kim, Jun-Il Yoo, Jin-Woo Kim; J Musculoskelet Trauma 2025;38(2):53-62. Published online March 24, 2025; DOI: https://doi.org/10.12671/jmt.2025.00010

Abstract PDF: Avulsion fractures occur when tendons or ligaments are subjected to forces greater than they can withstand at the apophysis or enthesis, regardless of fusion status. The pelvis and hip joint are vulnerable to these injuries due to the diverse muscular structures in these structures, which serve as origins for multiple muscles leading to the lower extremities. Pelvic avulsion fractures commonly affect young athletes, but can also occur in adults. The diagnosis typically involves assessing trauma history, a clinical examination, and radiographic imaging. If the diagnosis is unclear, additional tests such as computed tomography and magnetic resonance imaging may assist in the diagnosis and provide useful information for treatment decisions. While most avulsion fractures respond well to conservative treatment, surgical intervention may be preferred in severe displacements, cases of significant retraction in active athletes, or when a faster recovery is necessary. Chronic or neglected injuries may lead to excessive osseous formation around the pelvis, causing impingement syndromes. Recognizing characteristic radiological findings based on pelvic anatomy helps to make an accurate diagnosis, as chronic injuries can mimic tumors or infectious conditions, necessitating a careful differential diagnosis.

Easily missed nondisplaced fractures accompanying complete fractures in the lower extremity and pelvis: a narrative review: Young-Chang Park; J Musculoskelet Trauma 2025;38(1):5-12. Published online January 24, 2025; DOI: https://doi.org/10.12671/jmt.2025.00017

Abstract PDF: Nondisplaced fractures accompanying complete fractures are often difficult to detect on plain radiographs or computed tomography scans, posing a diagnostic challenge. The diagnosis of these frequently overlooked injuries can be delayed, potentially leading to suboptimal patient outcomes. This review discusses four commonly missed fracture patterns in the lower extremity and pelvis, including posterior involvement in fragility fractures of the pelvis, intertrochanteric extensions in isolated greater trochanter fractures, ipsilateral femoral neck fractures in high energy femoral shaft fractures, and posterior malleolar fractures in distal spiral tibial shaft fractures. An accurate diagnosis of these accompanying nondisplaced fractures is critical for optimizing surgical outcomes. Surgeons should incorporate thorough preoperative evaluations into their clinical practice to facilitate early detection and appropriate treatment strategies. Prompt identification and comprehensive management remain essential for improving patient outcomes.

Interpositional tricortical iliac bone graft in nonunion of midshaft clavicular fractures: Eun-Seok Son, Bum-Soon Park, Chang-Jin Yon, Chul-Hyun Cho; J Musculoskelet Trauma 2025;38(1):23-31. Published online January 24, 2025; DOI: https://doi.org/10.12671/jmt.2025.00004

Abstract PDF: Background
The purpose of this study was to investigate the radiological and clinical outcomes after interpositional tricortical iliac bone graft with plate fixation for the nonunion of clavicle midshaft fractures. Methods: Between 2007 and 2020, 17 cases who were treated by interpositional tricortical iliac bone graft with plate fixation for the clavicle midshaft nonunion combined with bone defect were investigated. The mean age was 53 years (range, 22–70 years). The mean follow-up period was 102.2 months (range, 18–193 months). Serial plain radiographs were used to evaluate radiological outcomes. The University of California, Los Angeles (UCLA) score, American Shoulder and Elbow Surgeons (ASES) score, and Quick-disabilities of the arm, shoulder, and hand (DASH) score were used to evaluate clinical outcomes. Complications were also evaluated. Results: All cases achieved complete bony union with mean healing time of 17.6 weeks (range, 14–22 weeks). The mean clavicle length difference was significantly decreased from 9.1 mm preoperatively to 2.6 mm postoperatively (P<0.001). The mean UCLA and ASES scores were significantly improved from 18.1 and 52.2 before surgery to 30.6 and 88.6 after surgery (both P<0.001), respectively. The mean final Quick-DASH score was 18.0. Three cases (17.6%) developed postoperative complications including two cases of shoulder stiffness and one case of screw irritation. Conclusions: Interpositional tricortical iliac bone graft with plate fixation for the clavicle midshaft nonunion demonstrated excellent radiological and clinical outcomes. In cases of atrophic nonunion combined with bone defect, this technique is an effective option that can provide structural support and restore clavicle length. Level of evidence: Level IV, case series.

Does the Operator’s Experience Affect the Occurrence of Complications after Distal Radius Fracture Volar Locking Plate Fixation? A Comparative Study of the First Four Years and Thereafter: Kee-Bum Hong, Chi-Hoon Oh, Chae Kwang Lim, Sungwoo Lee, Soo-Hong Han, Jun-Ku Lee; J Musculoskelet Trauma 2024;37(4):175-183. Published online October 25, 2024; DOI: https://doi.org/10.12671/jmt.2024.37.4.175; Correction in: J Musculoskelet Trauma 2025;38(1):40

Abstract PDF

Purpose
The management of distal radius fractures (DRFs) has evolved with the introduction of volar locking plate (VLP) fixation, offering stable fixation and better outcomes. Nevertheless, the impact of the surgeon’s experience on the complication rates in VLP fixation remains to be determined, particularly for less-experienced surgeons. This study compared the complication rates during the initial four years and subsequent two years of a hand surgeon’s practice of VLP fixation for DRFs.
Materials and Methods
The data between March 2016 and December 2022 were analyzed retrospectively under the Institutional Review Board approval. A single surgeon performed all VLP fixation surgeries after finishing regular hand surgery training, with the first four years representing the less experienced phase (Group 1) and the following two years indicating the experienced phase (Group 2). The patients’ characteristics, operation-related factors, and postoperative complications, including tendon injuries, nerve-related complications, fixation and instrument-related issues, osteosynthesis-related problems, and infections, were compared. In addition, the authors compared the data with a large multicenter study conducted by experienced hand surgeons.
Results
Three hundred and nineteen patients (321 wrists) were included. The mean age was 63.3 years, and 26.3% were male and 73.7% were female. The operation time was 53.7±14.5 minutes and 74.4±26.5 minutes in groups 1 and 2, respectively, which was statistically significantly shorter (p<0.001). The complication rates between the two groups were similar, except for the higher implant removal rates in Group 1. A comparison with a previous multicenter study revealed higher reduction losses and carpal tunnel syndrome in this study, but the overall complication rate was low.
Conclusion
In DRF management, when the operating surgeon has completed an accredited training course, VLP fixation is a good treatment method that can be performed effectively even by less experienced surgeons with low complication rates.

Avulsion Fractures of around the Hand: Dong Whan Kim, Jung Il Lee; J Korean Fract Soc 2024;37(3):158-168. Published online July 31, 2024; DOI: https://doi.org/10.12671/jkfs.2024.37.3.158

Abstract PDF: An avulsion fracture occurs when soft tissues, including the tendons and ligaments, are forcibly detached from the main bone by an external force. The hand contains numerous anatomical structures, such as ligaments, tendons, and volar plates, which are essential for maintaining multidirectional motion and joint stability. Excessive force applied in a specific direction can damage these structures, leading to avulsion fractures around the joint. These fractures can result in severe complications if left untreated or improperly managed, including joint deformity, contracture, nonunion or malunion of the fracture, secondary osteoarthritis, and limited range of motion. Therefore, an accurate examination, diagnosis, and appropriate treatment are crucial for preventing these adverse outcomes. An avulsion fracture can be managed conservatively when the avulsed fragment does not compromise joint stability or motion. Nevertheless, surgical intervention is required to stabilize the fragment if it affects joint stability or motion. The use of internal fixation has become more prevalent because of recent advances in small implants for fixation.

Avulsion Fractures around the Hip Joint and Pelvis: Ha-Yong Kim, Hajun Jang, Jung-Taek Kim, Jin-Woo Kim, Jun-Il Yoo, Won-Sik Choy, Yonghan Cha; J Korean Fract Soc 2024;37(3):150-157. Published online July 31, 2024; DOI: https://doi.org/10.12671/jkfs.2024.37.3.150

Abstract PDF: Avulsion fractures occur when tendons or ligaments are subjected to forces greater than they can withstand at the apophysis or enthesis, regardless of the fusion status. Given the diverse muscular structures around the pelvis and hip joint, which serve as origins for multiple muscles leading to the lower extremities, these areas are vulnerable to such injuries. Pelvic avulsion fractures commonly af-fect young athletes, but they can also occur in adults. Diagnosis typically involves assessing the trauma history, clinical examination, and radiographic imaging. In cases of unclear diagnosis, additional tests, such as computed tomography or magnetic resonance imaging, may assist in treatment decisions and diagnosis. Although most avulsion fractures respond well to conservative treatment, surgical interven-tion may be preferred in severe displacements, significant retraction in active athletes, or when a faster recovery is necessary. Chronic or neglected injuries may lead to excessive osseous formation around the pelvis, causing impingement syndromes. Recognizing the characteristic radiological findings based on the pelvic anatomy aids in accurate diagnosis because chronic injuries might mimic tumors or infectious conditions, necessitating a careful differential diagnosis.

Analysis of Missed Fractures by Bone Scan in Elderly Hip Fracture Patients with Osteoporosis: Tae Hun Lee, Yeong Hyun Lee, Seo Won Kang; J Korean Fract Soc 2024;37(3):144-149. Published online July 31, 2024; DOI: https://doi.org/10.12671/jkfs.2024.37.3.144

Abstract PDF: Purpose
The incidence of hip fractures is increasing due to an increase in elderly populations because elderly patients often have accompanying diseases, such as cognitive impairment or dementia, which may lead to missed fractures. Therefore, this study assessed the utility of bone scans in detecting missed fractures in elderly patients.
Materials and Methods
This study analyzed the data from 178 patients treated from January 2014 to March 2023. The inclusion criteria were patients who had hip fractures with osteoporosis over 70 years old. Bone scans were performed on average 10 days after injury. The rate and trend of missed fractures not detected in the initial diagnosis were determined based on sex, age, dementia status, and the presence of osteoporosis.
Results
Among the 178 hip fracture patients over 70 years old, 37 patients had a history of being diagnosed with dementia, and 141 patients had never been diagnosed. Missed fractures were confirmed in 49 cases (42 patients) (23.6%). The dementia group had 13 missed fractures, and the non-dementia group had 36 missed fractures, but there was no significant difference. Rib fractures were most common, followed by vertebral fractures.
Conclusion
Missed diagnoses of fractures were common among elderly hip fracture patients. A whole body bone scan appeared to be effective in detecting missed fractures. Therefore, identifying accompanying fractures through bone scans and delivering appropriate treatment can play an important role in postoperative rehabilitation.

Restoration of Lateral Tibial Plateau Widening and Articular Depression Is Necessary to Prevent Valgus Deformities after Arthroscopic Reduction and Internal Fixation in AO/OTA 41.B2 or B3 Fractures: Jun-Ho Kim, Kang-Il Kim, Sang-Hak Lee, Gwankyu Son, Myung-Seo Kim; J Korean Fract Soc 2024;37(3):125-136. Published online July 31, 2024; DOI: https://doi.org/10.12671/jkfs.2024.37.3.125

Abstract PDF: Purpose
This study examined the factors affecting valgus deformities after arthroscopic reduction and internal fixation (ARIF) in lateral joint-depression tibial plateau fractures.
Materials and Methods
Patients with lateral joint-depression tibial plateau fractures treated with ARIF were assessed retrospectively. The radiological evaluations included the articular depression distance (ADD) and the lateral plateau widening distance (LPWD) on preoperative and postoperative computed tomography. A postoperative valgus deformity was defined as valgus malalignment (mechanical axis ≥3°) and valgus deviation (Δmechanical axis of the operated knee from the healthy knee of ≥5°). Subgroup analyses based on a postoperative valgus deformity were performed to compare the clinical outcomes, including the range of motion, patient-reported outcomes measures, and failure and osteoarthritis progression. Furthermore, factors affecting the postoperative mechanical and Δmechanical axes were assessed.
Results
Thirty-nine patients were included with a mean follow-up of 44.6 months (range, 24-106 months). Valgus malalignment and valgus deviation were observed after ARIF in 10 patients (25.6%) and five patients (12.8%), respectively. The clinical outcomes were similar in patients with and without a postoperative valgus deformity. On the other hand, lateral compartment osteoarthritis progression was significantly higher in the valgus deformity group than in the non-valgus deformity group (valgus malalignment group: 50.0% vs 6.9%, p=0.007; valgus deviation group: 60.0% vs 11.8%, p=0.032). One patient with valgus deformity underwent realignment surgery at postoperative five years. The preoperative ADD and postoperative LPWD were significantly associated with the postoperative mechanical (both, p<0.001) and Δmechanical (ADD, p=0.001; LPWD, p=0.025) axes. Moreover, the lateral meniscectomized status during ARIF was significantly associated with the Δmechanical axis (p=0.019).
Conclusion
Osteoarthritis progression was highly prevalent in patients with postoperative valgus deformity. Thus, the restoration of lateral plateau widening and articular depression and preservation of the meniscus are necessary to prevent a valgus deformity after ARIF in lateral joint-depression tibial plateau fractures.

Comparison of Results between Minimally Invasive Plate Fixation and Antegrade Intramedullary Nailing of Recon-Type in Low-Energy Injury Distal Femoral Shaft Fractures: Hong Moon Sohn, Gwangchul Lee, Ba Rom Kim, Jung Soo Oh; J Korean Fract Soc 2024;37(2):87-94. Published online April 30, 2024; DOI: https://doi.org/10.12671/jkfs.2024.37.2.87

Abstract PDF: Purpose
This study compared the outcomes of minimally invasive plate osteosynthesis and antegrade intramedullary nailing for low-energy fracture of the distal femoral shaft.
Materials and Methods
A study was conducted on 30 patients who underwent surgery for low-energy fractures of the distal femoral shaft between January 2016 and April 2022. The study compared 15patients who underwent minimally invasive plate osteosynthesis (Group P) with 15 patients who underwent recon-type antegrade intramedullary nailing (Group N). We evaluated intraoperative blood loss, operative time, C-arm exposure time, bone density, final union status, anatomical reduction, and clinical evaluation. The complications were also examined, and statistical analysis was conducted to compare the two groups.
Results
The blood loss, surgery time, and C-arm time were similar in the two groups. The radiographic assessments and clinical evaluations were also similar in the two groups. The clinical results showed no difference between the groups. Group N had one case of nonunion and one case of delayed union, while Group P had one case of nonunion and one case of peri-prosthetic fracture.
Conclusion
Antegrade intramedullary nailing of the recon-type demonstrated comparable results to minimally invasive plate osteosynthesis. Hence, antegrade intramedullary nailing of the recon-type, which enhances stability by fixing the entire femur and providing additional fixation in the distal portion, is deemed appropriate for treating distal femoral shaft fractures.

Treatment of Avulsion Fractures around the Knee: Sumin Lim; J Korean Fract Soc 2024;37(2):117-124. Published online April 30, 2024; DOI: https://doi.org/10.12671/jkfs.2024.37.2.117

Abstract PDF: Avulsion fractures are common in athletes and result from high-impact or sudden, forceful movements involving the separation of a bone fragment at the ligament or tendon attachment site. The key focus areas include the anterior and posterior cruciate ligaments, medial collateral ligament, anterolateral complex, arcuate complex, medial patellofemoral ligament, patellar tendon, and quadriceps tendon. Diagnostic approaches combine radiography with advanced imaging techniques, such as computed tomography and magnetic resonance imaging, to elucidate the extent of injury and guide treatment decisions. Treatment ranges from conservative management for non-displaced fractures to surgical intervention for displaced fractures, with strategies customized based on the specific ligament involved and the nature of the fracture.

Avulsion Fractures in the Ankle and Foot: Gyeong Hoon Lim, Jae Won Kim, Sung Hyun Lee; J Korean Fract Soc 2024;37(2):102-116. Published online April 30, 2024; DOI: https://doi.org/10.12671/jkfs.2024.37.2.102

Abstract PDF: An avulsion fracture occurs when a muscle-tendon unit attached to a bone produces sufficient force to tear a fragment of the bone. If not treated properly, this injury can lead to deformity, nonunion, malunion, pain, and disability. Although avulsion fractures around the foot and ankle can occur anywhere there are tendon and ligament attachments, they are common in the anterior talofibular ligament, anterior-inferior tibiotalar ligament, calcaneal tuberosity, the base of the fifth metatarsal, and navicular bone. The optimal treatment for each fracture depends on the location and severity of the fracture. Conservative treatment involves limiting weight bearing for a period, splint immobilization, and using various orthoses. Surgical treatment is usually reserved for cases of severe displacement or when nonsurgical treatment has failed. The goals of surgery include reduction of the fracture fragment, prevention of nonunion or malunion and soft tissue injury, and early return to function. The decision for each treatment modality may depend on the patient demographics or preferences and the surgeon experience. This review summarizes previous and current views on the pathogenesis, diagnosis, and treatment of common avulsion fractures to guide the treatment and diagnosis.

Cephalomedullary Nailing with an Additional Cannulated Screw Fixation in Basicervical Femur Fractures: Keong-Hwan Kim, Woo Dong Nam, Yeon Sik Heo, Gu-Hee Jung; J Korean Fract Soc 2024;37(1):22-29. Published online January 31, 2024; DOI: https://doi.org/10.12671/jkfs.2024.37.1.22

Abstract PDF: Purpose
The purpose of this study is to analyze the clinical results of patients with basicervical fracture undergoing cephalomedullary nailing (CMN) with an additional cannulated screw fixation compared to only performing CMN. We hypothesized that a difference may exist in the clinical outcomes if an ad-ditional screw is fixed with CMN compared to only performing CMN in basicervical fracture.
Materials and Methods
A total of 28 consecutive patients who underwent CMN for basicervical fracture were included. In 9 cases, only CMN was conducted, and in 19 cases, an additional cannulated screw fixation was performed with CMN. Bone union, sliding distance, reduction status, and fixation failure were evaluated by postoperative radiography, and ambulatory ability was evaluated by functional results. These findings were compared between a group of CMN and a group of CMN with an additional cannulated screw.
Results
There were 4 males and 24 females with a mean age of 84 years (range, 69–100 years). No significant difference was found in postoperative reduction, tip-apex distance, bone union, and walking function recovery after surgery between the two groups, but in the sliding distance of the lag screw, the CMN group demonstrated more sliding (6.2 mm [range, 2.5–13.4 mm] vs 3.5 mm [range, 0.1– 9.2 mm]; p=0.045). Among the two groups, only one case of fixation failure at the postoperative four months was observed in the CMN group (p=0.321), and hemiarthroplasty with nail construct removal was performed.
Conclusion
CMN with additional cannulated screw fixation is a safe and reliable surgical option in basicervical fracture. It provided favorable clinical outcomes and may be a good alternative for treating basicervical fracture.

Short-term Treatment Comparison of Teriparatide and Percutaneous Vertebroplasty in Patients with Acute Osteoporotic Vertebral Compression Fractures: Joonoh Seo, Ki Youn Kwon, Bumseok Lee, Hoon-Sang Sohn; J Korean Fract Soc 2024;37(1):15-21. Published online January 31, 2024; DOI: https://doi.org/10.12671/jkfs.2024.37.1.15

Abstract PDF: Purpose
This study compared the 3-month treatment effects of teriparatide and percutaneous vertebroplasty for acute osteoporotic vertebral compression fractures.
Materials and Methods
A retrospective study was conducted on 76 patients diagnosed with acute osteoporotic vertebral compression fractures from January 1, 2020 to December 31, 2022. The patients were divided into the teriparatide group and the percutaneous vertebroplasty+alendronate group. The visual analog scale (VAS), Oswestry disability index (ODI), and height of the vertebrae anterior wall were measured before treatment and at 1 and 3 months after treatment.
Results
Of the 76 patients, 42 were treated with teriparatide, and 34 were treated with percutaneous vertebroplasty. The symptoms improved in both groups, with a decrease in the VAS and ODI scores at 1 and 3 months after treatment, respectively. On the other hand, there was no significant difference in the VAS, ODI score, and anterior vertebral body height between the two groups before treatment and at 1 and 3 months after treatment.
Conclusion
In the treatment of acute osteoporotic vertebral compression fractures, conservative treatment using teriparatide showed similar short-term (3 months) treatment results to percutaneous vertebroplasty in terms of improvement in back pain and function and degree of reduction in anterior vertebral body height.

Systematic Diagnosis and Treatment Principles for Acute Fracture-Related Infections: Jeong-Seok Choi, Jun-Hyeok Kwon, Seong-Hyun Kang, Yun-Ki Ryu, Won-Seok Choi, Jong-Keon Oh, Jae-Woo Cho; J Korean Fract Soc 2023;36(4):148-161. Published online October 31, 2023; DOI: https://doi.org/10.12671/jkfs.2023.36.4.148

Abstract PDF: Acute fracture-related infection (FRI) is a common and serious complication of fracture treatment. The clinical symptoms of the patient and the results of the serological, radiological, and histopathologi-cal examinations can be divided into ‘Confirmatory’ criteria and ‘Suggestive’ criteria, allowing for the diagnosis of FRI. Treatment principles can be broadly categorized into (1) the DAIR (Debridement, Antimicrobial therapy, Implant Retention) method and (2) the staged reconstruction method. The choice of treatment depends on factors such as the time elapsed after infection, stability of the internal fixation device, reduction status, host physiology, and virulence of the pathogens. Thorough surgical debridement and irrigation, ensuring stability at the fracture site, reconstruction of bone defects, and appropriate soft tissue coverage, along with antibiotic therapy, are essential to suppress or eradicate the infection. The restoration of limb function should be promoted through proper soft tissue coverage and bone union at the fracture site.

Fracture-Related Complications: What You Can Do to Prevent Infection: HoeJeong Chung, Jin Woo Lee, Sang-Ho Lee, Hoon-Sang Sohn; J Korean Fract Soc 2023;36(4):139-147. Published online October 31, 2023; DOI: https://doi.org/10.12671/jkfs.2023.36.4.139

Abstract PDF: Fracture-related infections (FRI) can occur when bacteria enter the wound during a traumatic injury. All efforts should be made to prevent FRI-associated complications due to the complexity of treatment at the time of onset and poor treatment outcomes. The risk factors for FRIs vary and several preoperative, perioperative, and postoperative measures can be implemented to prevent infections. Preoperative measures include blood sugar control, nutritional support, discontinuation of steroids and immunosuppressants, treatment of accompanying pre-existing infections, and decolonization of pathogens, specifically Staphylococcus aureus. The perioperative and postoperative measures include the use of prophylactic antibiotics, proper surgical site preparation (hair removal, preoperative washing, skin antisepsis), suitable surgical environment (operating room ventilation system, behavioral interventions in the operating room), correct surgical techniques (debridement, irrigation, wound closure, and negative pressure wound therapy). All medical staff should pay careful attention and ensure the implementation of the correct preventive measures.

Bone Union Time of Simple Distal Femur Fractures in the Elderly according to Fracture Gap after Treated with Minimally Invasive Plate Osteosynthesis: Young Ho Cho, Sangwoo Kim, Jaewook Koo; J Korean Fract Soc 2023;36(4):133-138. Published online October 31, 2023; DOI: https://doi.org/10.12671/jkfs.2023.36.4.133

Abstract PDF: Purpose
This study examined the difference in bone union time according to the fracture gap after minimally invasive plate osteosynthesis (MIPO) for simple distal femoral fractures in elderly patients.
Materials and Methods
From January 2010 to December 2019, patients aged 60 years or older who underwent surgical treatment for distal femoral fractures due to a low-energy injury were investigated retrospectively. Forty patients were enrolled in the study. The patients were divided into two groups according to the fracture gap after reduction: no more than 2 mm (Group A) and more than 2 mm (Group B) in the anteroposterior and lateral plane. The demographic, operation time, presence or absence of cerclage wiring, plate screw density, plate span ratio, plate length, bone union period, non-union, and complications were evaluated.

No statistical differences in operation time, cerclage wiring, plate screw density, plate span ratio, and plate length were observed between the two groups, and the bone union was achieved in all patients without complication. The bone union period was 17.24±1.48 weeks in Group A and 24.53± 5.20 weeks in Group B, which was statistically significant (p<0.001).
Conclusion
The bone union time in treating geriatric simple distal femur fractures using the MIPO tech-nique was significantly shorter in the 2 mm or less fracture gap than in the greater than 2 mm group.

Outcomes of Minimally Invasive Surgery in Intra-Articular Calcaneal Fractures: Sanders Type III, Joint Depressive Type Calcaneal Fracture: Je Hong Ryu, Jun Young Lee, Kang Yeol Ko, Sung Min Jo, Hyoung Tae Kim; J Korean Fract Soc 2023;36(3):85-94. Published online July 31, 2023; DOI: https://doi.org/10.12671/jkfs.2023.36.3.85

Abstract PDF: Purpose
To evaluate the radiologic and clinical outcomes of a minimally invasive technique using the tarsal sinus approach in the management of Sanders type III, joint depressive type calcaneal fractures.
Materials and Methods
Between July 2011 and September 2019, data of 29 patients who underwent a minimally invasive procedure with the sinus tarsi approach for Sanders type III joint depressive intra-articular calcaneal fractures, and were followed up for more than 1 year were analyzed. We evaluated the radiologic outcomes by assessing the radiologic parameters (Böhler angle, Gissane angle, calca-neal length, calcaneal height, calcaneal width). We also evaluated the clinical outcomes based on the American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score and the complications associated with the technique.
Results
The radiological results showed an improvement in the Böhler angle from 2.5° to 18.6° and the Gissane angle from 132.4° to 119.1° after the operation. The mean AOFAS score during the clini-cal evaluation was 79.5. We observed 13 cases of posttraumatic arthritis, 1 case of subtalar arthrodesis, and no case of wound complication.
Conclusion
Minimally invasive technique for Sanders type III joint depressive calcaneal fractures resulted in relatively satisfactory radiologic and clinical outcomes. Open reduction and internal fixation through the sinus tarsi approach reduce complications including wound problems. This approach offers satisfactory results without long-term complications.

Single Percutaneous Retrograde Anterior Column Screw Fixation in a Minimally Displaced Transverse Acetabular Fracture - A Case Report -: Seungyup Shin, Jinkyu Park, Sungho Lee; J Korean Fract Soc 2023;36(2):57-61. Published online April 30, 2023; DOI: https://doi.org/10.12671/jkfs.2023.36.2.57

Abstract PDF: According to the Letournel classification, a transverse fracture is the only elementary fracture pattern that breaks both the anterior and posterior border of the innominate bone. A transverse acetabular fracture separates the innominate bone into two segments: the iliac segment and the ischiopubic segment. Therefore, minimally displaced transverse fractures can be stabilized by purchasing both segments with a large-diameter single screw. Although it is not a stable internal fixation construct compared with plates and screws, it provides sufficient stability to promote early mobilization and early weight-bearing while minimizing the risk of secondary displacement and preventing secondary complications associated with prolonged bed rest and immobilization. The authors successfully treated a case of minimally displaced transverse acetabular fracture with percutaneous column fixation using a retrograde fashion of a single anterior column screw. This report discusses the case with a literature review and deliberates the usefulness of the procedure.

Demographic and Radiographic Parameters as Predictors of Reduction Loss after Conservative Treatment of Distal Radius Fractures in Adults: Kyu Jin Kim, Dae Won Shin, Seong Kee Shin; J Korean Fract Soc 2023;36(2):45-51. Published online April 30, 2023; DOI: https://doi.org/10.12671/jkfs.2023.36.2.45

Abstract PDF: Purpose
This study examined the demographic and radiological risk factors for later reduction loss of distal radius fractures treated conservatively. Materials and Methods This study enrolled patients treated for distal radius fractures between January 2017 and December 2019. Seventy-eight patients were included in the analysis and divided into two groups. The patients who showed minimal reduction loss within an acceptable radiologic angle after initial manual reduction were classified as Group A. The patients who showed reduction loss out of an acceptable radiologic angle and finally malunited or converted to surgical treatments were classified as Group B. The patient’s age and bone marrow density were used as demographic data. The initial X-ray images were evaluated to determine the fracture type. Various radiological parameters were measured. Results The 78-patient study cohort consisted of nine men and 69 women with a mean age of 67 years. Forty-eight cases were sorted into Group A, and 30 cases into Group B. On logistic regression analysis, the age of 80 or older was a risk factor for later fracture displacement among the demographic factors (p=0.037, odds ratio=4.937). Among the radiographic factors, the presence of distal ulnar fracture and dorsal cortical comminution were disclosed as risk factors of later displacement (p=0.049, 0.003, odds ratio=3.429, 7.196). Conclusion When conservative management for distal radius fracture is decided in patients more than 80 years of age or accompanied by a distal ulnar fracture or with dorsal cortical comminution, the possibility of later displacement of the distal radius should be considered.

Fragility Fractures of the Pelvis and Sacrum: Se-Won Lee, Ju-Yeong Kim; J Korean Fract Soc 2023;36(1):29-38. Published online January 31, 2023; DOI: https://doi.org/10.12671/jkfs.2023.36.1.29

Abstract PDF: The incidence of fragility fractures of the pelvis (FFP) has increased significantly due to the aging popu-lation and improved diagnostic modalities. The evaluation and treatment of these patients differ from that of high-energy pelvic ring injuries typically seen in younger patients. Therefore, it is important to classify the FFP by patterns of the classification system to standardize optimal treatment criteria and appropriate treatment strategy. However, some cases are not classifiable according to the FFP classifi-cation. A newly proposed classification that can be verified by comparing existing FFP classifications is needed to overcome the weak points. Non-operative treatment is usually considered first and should focus on early mobilization. Operative fixation should focus on stabilizing the minimally invasive pelvic ring than the reduction of fractures to facilitate early mobilization and avoid complications that can arise from comorbidities associated with immobility.

Isolated Avulsion Fracture of the Subscapularis from the Lesser Tuberosity of the Humerus in a 12-Year-Old Boy - A Case Report -: Shin Seung Park, Chung Shik Shin, Won Bin Song; J Korean Fract Soc 2022;35(2):68-73. Published online April 30, 2022; DOI: https://doi.org/10.12671/jkfs.2022.35.2.68

Abstract PDF: An isolated avulsion fracture of the subscapularis from the lesser tuberosity of the proximal humerus is rare in the pediatric population and only a couple of cases have been described in literature. A 12-yearold right-handed boy, was admitted to the hospital with left shoulder pain after falling down the previ-ous day. Physical examination revealed tenderness on the lesser tuberosity and intertubercular groove of the humerus and a limited range of motion. Ultrasonography, computed tomography, and magnetic resonance imaging showed an isolated avulsion fracture of the subscapularis tendon from the lesser tuberosity of the humerus, accompanied by medial subluxation of the long head of the biceps tendon. In this case, a subscapularis avulsion fracture which is rare in this age group was detected at an early stage, and surgical treatment resulted in positive outcomes. Subscapularis avulsion fractures in children are difficult to diagnose in the early stages, and if not treated on time, the symptomatic improvement may be delayed. Timely and accurate diagnosis and treatment can help faster return to normal activi-ties. We would therefore like to report this case with a literature review.

The Antibiotic Cement Coated Nail and Masquelet Technique for the Treatment of Infected Nonunion of Tibia with Bone Defect and Varus Deformity: Min Gu Jang, Jae Hwang Song, Dae Yeung Kim, Woo Jin Shin; J Korean Fract Soc 2022;35(1):26-30. Published online January 31, 2022; DOI: https://doi.org/10.12671/jkfs.2022.35.1.26

Abstract PDF: Infective nonunion after fracture surgery can cause persistent pain and inflammatory exudate in patients, requiring long-term treatment. To treat infective nonunion, radical debridement of infective bone and soft tissue should be performed, followed by stable internal fixation and bone graft. Multiple treatment strategies need to be considered according to the classification of chronic osteomyelitis, size of the bone defect, degree of bone malalignment, and severity of the soft tissue injury. This paper reports a case of a patient treated with an antibiotic cement-coated nail and a Masquelet technique to treat the infected nonunion of the tibia with a bone defect and varus deformity.

Early Corrective Osteoclasis for Malunited Pediatric Medial Condylar Fracture of the Humerus: Hong Jun Jung, Ho Youn Park, Yuna Kim; J Korean Fract Soc 2022;35(1):21-25. Published online January 31, 2022; DOI: https://doi.org/10.12671/jkfs.2022.35.1.21

Abstract PDF: Fractures of the medial condyle of the distal humerus in children are very rare, and the younger the age, the more difficult it is to diagnose. These fractures include an intra-articular fracture and a Salter–Harris type IV growth plate fracture. Therefore, the prognosis is poor if the fracture is neglected or misdiag-nosed because of the high incidence of complications such as nonunion, angular deformity, or joint contracture. This paper reports a case of a four-year-old child who presented with a malunion of the medial condyle of the humerus with good results after an early corrective osteoclasis.

Denosumab (RANKL Inhibitor): A Potent Anti-Resorptive Agent: Seong-Eun Byun; J Korean Fract Soc 2021;34(4):142-147. Published online October 31, 2021; DOI: https://doi.org/10.12671/jkfs.2021.34.4.142

Abstract PDF: Denosumab, a fully human monoclonal antibody to the receptor activator of nuclear factor-kappa B ligand, was introduced and used as an anti-osteoporotic agent. Denosumab prevents bone resorption by inhibiting the differentiation and action of osteoclasts, resulting in an increase of bone mineral density and broad-spectrum anti-fracture efficacy. Clinical studies, including FREEDOM (Fracture Reduction Evaluation of Denosumab in Osteoporosis Every Six Months) and its extension up to 10 years, FREEDOM Extension, demonstrated its long-term efficacy and safety in postmenopausal osteoporosis. In addition, the efficacy and safety of denosumab were confirmed in male osteoporosis and glucocorticoid- induced osteoporosis. Therefore, recent clinical guidelines recommend denosumab as an initial treatment. This review summarizes the mechanism of action, pharmacological characteristics, efficacy, and safety issue of denosumab.

Operative Positioning Technique for an Intertrochanteric Fracture in a Patient with an Ipsilateral Above-the-Knee Amputation - Technical Note -: Dae-Hyun Park, Yong-Uk Kwon, Dong-Seok Kim; J Korean Fract Soc 2021;34(4):137-141. Published online October 31, 2021; DOI: https://doi.org/10.12671/jkfs.2021.34.4.137

Abstract PDF

A 45-year-old man with a remote history of a left above-the-knee amputation presented to the emergency department with left hip pain after a mechanical fall. This case was an operative challenge because commonly used intraoperative traction methods could not be applied to a patient with an above-the-knee amputation. We describe a rarely utilized surgical technique of applying traction to an amputated extremity via a Steinmann pin during closed reduction and internal fixation of an intertrochanteric fracture.

Current Concepts of Vitamin D and Calcium in the Healing of Fractures: Jihyo Hwang; J Korean Fract Soc 2021;34(3):117-121. Published online July 31, 2021; DOI: https://doi.org/10.12671/jkfs.2021.34.3.117

Abstract PDF: Fragile fractures, also known as osteoporosis fractures, insufficiency fractures, and senile fractures are a significant problem encountered by orthopedic surgeons. Calcium and vitamin D are essential for maintaining bone health and deficiencies in calcium and vitamin D are major risk factors for the development of osteoporosis. Sufficient amounts of calcium are also required for fracture-callus mineralization. Hence, compromised bone repair that is frequently observed in osteoporotic patients might be attributed to calcium and vitamin D deficiencies. Consequently, calcium and vitamin D supplementation represents a potential strategy for treating compromised fracture healing in osteoporotic patients. There is some clinical evidence of the positive effect of supplementation in fracture healing and posttraumatic bone turnover, but research in this area is ongoing. Calcium and vitamin D should be the primary treatment of choice in osteopenic patients with an insufficiency of calcium and vitamin D and for the prevention of secondary osteoporotic fractures. Calcium and vitamin D can also be used as addition to other primary osteoporotic medications such as antiresorptive or bone-forming agents. The role of calcium and vitamin D in fracture healing and the therapeutic potential of calcium and vitamin D supplementation is summarized in this context.
