Fracture of the Talus: Tae Jung Bang, Sun Kyu Kim, Hyung Jin Chung; J Korean Fract Soc 2016;29(3):213-220. Published online July 31, 2016; DOI: https://doi.org/10.12671/jkfs.2016.29.3.213

Abstract PDF: Although talus fractures are uncommon, proper management is important because they are often associated with severe complications. Talar neck and body fractures occupy most of the talar fractures. It remains controversial whether talar neck fractures require emergent or elective treatment. Elective definitive fixation, however, may reduce risks of wound complications. Many surgeons recommend dual surgical approachesâ€”anteromedial and anterolateralâ€”to allow accurate visualization and anatomic reduction. Although there are various methods of fixation, the use of plates is necessary in comminuted talar fractures. Outcomes may vary and will be dependent on the degree of the initial fracture displacement. It is necessary to restore articular congruency and axial alignment for normalizing hindfoot function. Common complications include posttraumatic arthritis, avascular necrosis, malunion, and nonunion.

Iatrogenic Subtrochanteric Fractures Related to the Surgical Error: Two Cases Report: Kook Jin Chung, June Young Jeon, Hyun Woo Na, Ji Hyo Hwang; J Korean Fract Soc 2015;28(4):250-255. Published online October 31, 2015; DOI: https://doi.org/10.12671/jkfs.2015.28.4.250

Iatrogenic fracture is not popular and might be recognized as a malpractice. Surgical error related to iatrogenic fracture which has occurred after an operation can be detected only by a surgeon. Stress riser fracture is another form of iatrogenic fracture also known as a Young's modulus fracture. As the majority of surgical related stress riser fractures can be preventive, the accurate prevalence is not known. The majority of fractures occurred in the weight bearing bones such as femur and tibia. The subtrochanter area is the most stress concentrated area in the human body, thus it is a common area for occurrence of stress riser iatrogenic fractures. We experienced 2 cases of stress riser iatrogenic fractures, which are related to technical errors, thus we report cases with literature review.

Results of Asian Type Gamma 3 Nail in Treatment of Trochanteric Fractures: Bing Zhe Huang, Yong Wook Park, Jin Su Park, Kyu Cheol Noh, Soung Yon Kim, Kook Jin Chung, Hong Kyun Kim, Hyong Nyun Kim, Yong Hyun Yoon, Ji Hyo Hwang; J Korean Fract Soc 2014;27(3):213-221. Published online July 31, 2014; DOI: https://doi.org/10.12671/jkfs.2014.27.3.213

Abstract PDF

PURPOSE
This study was conducted in order to demonstrate the radiologic and clinical results of using the Asian type gamma 3 nail in treatment of trochanteric fractures.
MATERIALS AND METHODS
Patients underwent operations with gamma 3 nails between August 2010 and August 2012. For the radiologic evaluation, we analyzed bone quality, fracture pattern, reduction quality, union period, and position of lag screw (tip-apex distance, Cleveland index). For the clinical evaluation, we analyzed mobility score of Palmer and Parker and Jensen's functional score.
RESULTS
The mean union was taken at 17.4 weeks (14-25 weeks). Two cases (4.3%) underwent reoperation due to cutting out of the hip screws. The clinical outcomes of Parker and Palmer's average mobility score changed from 7.3 to 5.8 (79%), Jensen's functional score was 1.3 to 1.8 (72%).
CONCLUSION
We achieved excellent clinical and radiological outcomes; therefore, Asian type gamma 3 nail is effective in treatment of trochanteric fractures of the femur in Korea.

Published online July 31, 2014; DOI: https://doi.org/10.12671/jkfs.2014.27.3.206

Abstract PDF

PURPOSE
The purpose of this study is to evaluate the results of tension band wiring and additional circumferential wiring in treatment of comminuted patella fractures.
MATERIALS AND METHODS
A retrospective study of 67 patients with follow-up period longer than six months who underwent tension band wiring and additional circumferential wiring for comminuted patellar fracture from January 2004 to December 2012 was conducted. Analysis was based on radiological evaluation of bony union and articular surface displacement, and clinically by evaluating the postoperative function of the knee joint using the Levack scoring system.
RESULTS
Only one case out of 67 (1.5%) showed nonunion without metal breakage while good bone union was achieved in all other cases. Excluding the nonunion case, range of motion was 90 degrees minimum, 135 maximum, 129 on average. Average displacement was less than 2 mm, and 64 out of 67 cases showed satisfactory outcome with excellent functional score according to the Levack scoring system.
CONCLUSION
Tension band wiring and additional circumferential wiring technique for treatment of comminuted patella fractures can be considered as an effective treatment for achievement of good bone union and restoration of normal knee function.

Checkrein Deformity by Incarcerated Posterior Tibial Tendon and Displaced Flexor Hallucis Longus Tendon following Ankle Dislocation: A Case Report: Su Young Bae, Hyung Jin Chung, Man Young Kim; J Korean Fract Soc 2011;24(3):271-276. Published online July 31, 2011; DOI: https://doi.org/10.12671/jkfs.2011.24.3.271

Abstract PDF

We report a case of 20 year-old man who had unusual equinus and checkrein deformity following dislocation of his right ankle joint. He had been treated with distal tibiofibular screw fixation and external fixation. After removal of external fixator, he had suffered from progressive deformity of foot and ankle. Widening of distal tibiofibular joint and medial clear space was found on radiograph and it was revealed that posterior tibial tendon had been dislocated and incarcerated into the distal tibiofibular joint on MRI. We corrected the deformity with excision of incarcerated posterior tibial tendon, adhesiolysis and lengthening of flexor hallucis longus tendon, reconstruction of deltoid ligament and flexor digitorum longus tendon transfer.

Published online January 31, 2007; DOI: https://doi.org/10.12671/jkfs.2007.20.1.58

Abstract PDF: PURPOSE
To evaluate the results of the treatment of the supracondylar fractures of the humerus according to the fixation methods with cannulated screw.
MATERIALS AND METHODS
Eight patients, aged 49 to 82 years (average, 65 years), were reviewed after a mean follow-up of 16 months (range, 12~24 months). According to AO classification all fractures were classified as type A2 (simple transverse supracondylar fracture). All patients underwent closed reduction. Percutaneous fixation with cannulated screws was performed in 8 patients. Three of 8 patients had associated medical problems and one patient had distal radius fracture. The functional results were assessed by the Mayo Elbow Performance Score.
RESULTS
Mean operation time was 59 minutes (45~75) and all the patients with cannulated screw fixation had bony union and were able to early ROM exercise. Mean ranges of motion was 5~120 degrees with excellent functional results. Functional evaluation of elbow joint by Mayo method showed mean value of 88 (75~95).
CONCLUSION
The cannulated screw fixation of supracondylar fracture of humerus, especially in the elderly aged group with medical disease had excellent functional results (rigid fixation & early ROM exercise) due to shortening of surgery time and anesthesic time, combined with decreased technical difficulties of the surgical procedure

Published online April 30, 2006; DOI: https://doi.org/10.12671/jkfs.2006.19.2.271

Abstract: PURPOSE
To evaluate the efficacy of Flexible intramedullary pin fixation in pediatric forearm diaphyseal fractures.
MATERIALS AND METHODS
In this retrospective study, we reviewed 15 cases of forearm diaphyseal fractures operated using flexible intra-medullary nail fixation technique between January 2000 and December 2004. Of these 15 children, there were 11 boys and 4 girls with an average age of 11.6 years (range, 7~15 years). The implants were introduced in the distal radius and proximal ulna in all patients. An average duration of fixation was 5.3 months in the radius, 4.7 months in the ulna. After operation, all patient were applied with a long arm cast and the duration of immobilization was 5.2 weeks (range, 4~6 weeks) on average.
RESULTS
All fractures in this series healed with normal range of supination (average 80.0) and pronation (average, 71.6 degrees). Average operation time including anesthesia was 123 minutes and hospital stay was 5.4 days. Time to union was 8.4 weeks on average. Range of motion and functional results were satisfactory in all cases. There were one case of incomplete ulnar nerve injury and two cases of refracture which were treated conservatively without any permanent complication.
CONCLUSION
Flexible intramedullary pin fixation technique is a good method in case of unstable displaced fracture and difficult or failed closed treatment.

Two-part and Three-part Fractures of the Proximal Humerus Treated with the Polarus Interlocking Nail: A Comparison of Fracture Types: Kyu Cheol Noh, Yung Khee Chung, Kook Jin Chung, Sung Ku Hong; J Korean Fract Soc 2006;19(2):182-187. Published online April 30, 2006; DOI: https://doi.org/10.12671/jkfs.2006.19.2.182

Abstract

PURPOSE
To evaluate the radiographic and clinical outcomes of patients with displaced proximal humerus fractures (two-part and three-part) treated with the Polarus interlocking nail, comparing their fractures types.
MATERIALS AND METHODS
There were 22 patients with displaced proximal humerus fractures. There were 10 surgical neck (SN) and 1 anatomical neck (AN) two-part fractures and 10 greater tuberosity/surgical neck (GT/SN) and 1 GT/AN three-part fractures. All patients were surgically treated solely with the Polarus interlocking nail using a closed technique. Functional assessment was obtained using the American Shoulder and Elbow Surgeons (ASES) score, which grade outcomes as excellent (>75), satisfactory (50~75), poor (<50) results. Radiographic outcome measurements included fracture alignment (neck-shaft angle), loosening of screw, fixation and hardware failure, and malunion and nonunion.
RESULTS
Overall, the average ASES score was 80.2 (range 46.0 to 98.0). There were 15/22 (68.2%) excellent, 6/22 (27.3%) satisfactory, and 1/22 (4.5%) poor results. All shoulders healed radiographically without evidence of avascular necrosis of the humeral head. When comparing patients with two-part fractures (n=11) with patients having three-part fractures (n=11), there were statistically significant differences with ASES outcome measures (p<0.05). But, there were no statistically significant differences in age-related analysis (p>0.05).
CONCLUSION
Both displaced two-part fractures and three-part GT/SN fractures can have above satisfactory functional and radiographic outcomes with the Polarus interlocking nail using a closed technique. Even though displaced three-part GT/SN fractures in elderly osteopenic patients (>60 years), we treated successfully with the Polarus interlocking nail.

Subtalar Distraction Arthrodesis for Calcaneal Malunion: Hyung Jin Chung, Jae Kwang Yum, Kook Jin Chung, Jae Min Jeon; J Korean Fract Soc 2006;19(1):34-40. Published online January 31, 2006; DOI: https://doi.org/10.12671/jkfs.2006.19.1.34

Abstract

PURPOSE
To evaluate the results and efficacy of the subtalar distraction arthrodesis on patients with complications due to malunion after intra-articular calcaneal fracture.
MATERIALS AND METHODS
From October 2001 to September 2004, we operated on 10 patients (14 cases). There were 9 male patients and one female; their mean age was 41 years old. Ten cases among them were operated initially. The mean period between initial injury and arthrodesis was 18 months. The mean follow up period was 16 months. During the operation, we used extensile lateral approach and arthrodesis was performed using tricortical bone block and cannulated screws. The ankle-hindfoot scale was used for clinical evaluation. In radiologic analysis, plain X-ray and CT of the both feet were examined for union and various parameters.
RESULTS
Thriteen cases achieved radiologic bone union. The mean ankle-hindfoot scale (maximum: 94 points) increased from 52.4 points preoperatively to points 77.2 at the final follow-up. The radiologic analysis of the pre and postoperative standing lateral radiograph showed mean increase of 6.9 mm in talo-calcaneal height, 5.2 degrees in talocalcaneal angle, 4.3 degrees in talar declination angle and average decrease of 4.5 degrees in talo-first metatarsal angle.
CONCLUSION
The short term result of the subtalar distraction arthrodesis using tricortical bone block was promising, but longer follow-up will be needed.

Long Term Results of Retrograde Nailing in Adult Femoral Shaft Fractures: Yerl Bo Sung, Soo Chul Park, Jong Kuk Ahn, Jae Kwang Yum, Hyung Jin Chung, Jin Ho Kim, Seung Taek Song, Yong Taek Han; J Korean Soc Fract 2002;15(3):356-362. Published online July 31, 2002; DOI: https://doi.org/10.12671/jksf.2002.15.3.356

Abstract PDF

PURPOSE
Antegrade intramedullary nailing of the femur is effective method of treatment for patients with femoral shaft fractures. But retrograde IM nailing is another effective method, especially in femoral shaft fractures concomitant with ipsilateral femoral neck, intertrochanteric fractures, acetabular fracture, multiple fracture and obesity, pregnancy, traumatic arthrotomy of the knee joint, bilateral femur fractures, and floating knee injuries are also indicated. The purpose of this study is to verify the effectiveness of retrograde IM nailing after long-term follow-up by retrospective evaluation.
MATERIALS AND METHODS
A retrospective review of the medical charts and X-rays about 37 patients who were operated by retrograde nailing and all patients were minimally followed up about 2 years. Results were evaluated radiologically for screw breakage, nail migration, nonunion and clinically for knee ROM limitation, infection.
RESULTS
The results were as follows; 1) union was achieved at on average of 17 weeks. 2) Full range of knee motion was gained in 33/37 cases. Knee-stiffness occurred in 4 cases, Severity of initial trauma might affect such results but not, retrograde nailing 3) 2 complications were found nonunion and delayed union. 4) There were not postoperative infection and femoral shortening. There were distal screw breakage in 4 cases but, the others were not migrated.
CONCLUSION
Retrograde IM nailing of femoral fracture is an effective method in selected cases such as ipsilateral femoral neck fractures, floating knees, post-TKRA femoral fracture and so on. If retrograde IM nailing is operated by skillful surgeon and appled to absolute indication, the result is no significant difference of antegrade IM nail such as bone union, nonunion and postoperative infection. Nevertheless, operation time is shorter and blood loss lesser. Significant knee problems related to this technique could not be identified for 2 years followed up.

Comparison of External Fixation and Interlocking IM Nail in Open Tibial Fractures: Hyung Jin Chung, Duck Kyu Kim, Yerl Bo Sung, Jong Guk Ahn; J Korean Soc Fract 2001;14(4):632-642. Published online October 31, 2001; DOI: https://doi.org/10.12671/jksf.2001.14.4.632

Abstract PDF: PURPOSE
To compare and analyze the results of the treatment based on the method of treatment between interlocking IM nail and external fixation of type II, III A, and III B open fractures of the tibia] shaft.
MATERIALS AND METHODS
A clinical analysis was performed on 57 cases of type II, III A, and III B open fractures of tibial shaft from January 1994 to October 1999 those studies are followed at least 1 year or more. The results was analyzed according to complications and functional results based on operative methods of types of open fractures.
RESULTS
In aspect of delayed union and nonunion, interlocking IM nail indicate a great results(p = 0.036) in type II. In angulation, interlocking IM nail marks an outstanding results in case of type II. There is no difference between interlocking IM nail and external fixation in infection. But, the delay of operation after injury increase the possibilities of infection.
CONCLUSION
At present, especially in type m, external fixation was preferred. But, interlocking IM nail has a good results in aspect of complications. Therefore unreamed intramedullary nailing for open tibia shaft fractures is a good treatment method to be recommended.

Published online January 31, 2000; DOI: https://doi.org/10.12671/jksf.2000.13.1.178

Abstract PDF: PURPOSE
: This study analyzed clinical and biomechanical data from patients with elbow fracture dislocation to correlate long-term objective result with the specific injury type and treatment rendered. This can provide a basis for the management of this difficult injuries.
MATERIALS AND METHODS
: Fifteen patients with elbow dislocation were studied from October, 1992 to October, 1997 in Sang-Gye Paik Hospital. The average duration of follow up was 4.2 years.
RESULTS
: On the basis of an objective functional grading score that included elements of pain, motion, strength, and stability, the results were excellent in five(33%), good in five(33%), fair in one(7%), poor in four(27%). Prolonged immobilization greater than four weeks was associated with poor results. The results were closely related to the combined injuries and duration of immobilization. In case of radial head fractures, the best result was obtained in patients with Mason type II fractures treated by open reduction and internal fixation using Herbert screw and early complete radial head excision. SUMMARY AND CONCLUSION : The most common combined injury is radial head fracture. Early complete radial head excision and encouraging early ROM had more satisfactory result than delayed radial head excision or internal Fixation for Mason type III fracture.

Published online October 31, 1999; DOI: https://doi.org/10.12671/jksf.1999.12.4.1034

Abstract PDF: Fracture of the lateral condyle of humerus in children are common injury next to supracondylar fracture in children, account for 10 to 15% about the elbow and 18 to 20% about distal humerus fractures. This is the one fracture that can be overlooked clinically and that has a high potential for nonunion and cubitus valglls deformity. Sixty children treated by closed or open reduction with internal fixation on the lateral condyle fracture of humerus from January 1994 to August 1997, were reviewed. Almost fractures were treated within 12 hours after injury for the purpose of prevention of further displacement and occurrence of complication. According to Hardacre et als criteria, most patients showed excellent and good results. We report the result after surgical treatment on the laterdl condyle fracture of humerus in children.

Compartment Syndrome Complicating Avulsion Fractures of the Tibial Tubercle: Yerl Bo Sung, Jin Hyok Kim, Hyung Jin Chung, Dong Soo Kim, Byung Hyun Jung, Jong Guk Ahn, Chil Soo Kwon, Kook Jin Chung, Bong Gyun Kang; J Korean Soc Fract 1999;12(2):284-289. Published online April 30, 1999; DOI: https://doi.org/10.12671/jksf.1999.12.2.284

Abstract PDF: Avulsion of the tibial tubercle is an uncommon physeal injury. Complications from this fracture have rarely been reported and seldom affect the long-term outcome. Three adolescent boys who sustained avulsion fracture of the tibial tubercle, were complicated by compartment syndrome and treated at Inje University Sang-Gye Paik Hospital from September 1989 to February 1995. Injury to the soft tissue surrounding the tibial tubercle avulsion may be more extensive than is usually appreciated. The anatomy of the proximal tibia and the tibial tubercle with nearby branches of the anterior tibial recurrent artery suggest a predisposing factor for the development of compartment syndrome. So, compartment syndrome should be added to the list of possible complications of this type of fracture.

The Results of the Percutaneous K-wire Fixation for the Supracondylar Fractures of the Humerus in Children: Chil Soo Kwon, Jong Kuk Ahn, Byung Hyun Jeong, Jin Chung, Ho Cheol Rhee; J Korean Soc Fract 1999;12(1):187-193. Published online January 31, 1999; DOI: https://doi.org/10.12671/jksf.1999.12.1.187

Abstract PDF: The cases of 160 patients who had a displaced supracondylar fracture of the humerus were reviewed retrospectively. According to the Flynn's criteria, the results of treatment were excellent 33%, good 53%, fair 10%, poor 4%. No neurovascular complication was appeared. In two cases, cubitus varus deformity was appeared to be related with incorrect reduction. We believe that percutaneous k-wire fixation is excellent method in treatment of the displaced supracondylar fractures in children. There was no significant difference of clinical results among methods of percutaneous K-wire fixation but lateral 2 and medial 1 cross pinning has advantages : easy technique in insertion of lateral 2 pins, biomechanical stability and removal of medial pin in the irritation of ulna nerve without significant influence of stability.

A Clinical Study of the Tibial Pilon Fractures: Chil Soo Kwon, Jong Kuk Ahn, Jin Hyok Kim, Yerl Bo Sung, Hyung Jin Chung; J Korean Soc Fract 1997;10(2):338-345. Published online April 30, 1997; DOI: https://doi.org/10.12671/jksf.1997.10.2.338

Abstract PDF: The pilon fracture result from axial compression and rotational forces causing variable degrees of metaphyseal disruption, articular damage, and malleolar displacement. It is managements are closed reduction and plaster immobilization, skeletal traction, fibular stabilization alone, limited open reduction and extemal fixation, primary arthrodesis, and even immediate amputation. Recently limited open reduction and external fixation has been proved to provide good clinical results for the severely comminuted or open pilon fractures. Authors reviewed 20 cases of the pilon fractures. Among them 10 cases were treated with limited open reduction and external fixation from October 1989 to January 1994. The results were as follows : 1. Age distribution was from 14 years to 77 years(mean ; 47 years). 2. Of the 20 cases, male were 14, and female were 6. 3. The cause of injury were tracffic accident in 10 cases, slip down in 6 and fall from a height in 4. 4. The most frequent type of fractures was type III(12 cases : 60%) according to Ruedi and Allgower classification. 5. Limited open reduction and external fixation(10 cases) has shown better results than classic open recduction and internal fixation for severely comminuted or open pilon fractures.
