Comparison of Clinical Outcomes for Femoral Neck System and Cannulated Compression Screws in the Treatment of Femoral Neck Fracture: Jae Kwang Hwang, KiWon Lee, Dong-Kyo Seo, Joo-Yul Bae, Myeong-Geun Song, Hansuk Choi; J Korean Fract Soc 2023;36(3):77-84. Published online July 31, 2023; DOI: https://doi.org/10.12671/jkfs.2023.36.3.77

Abstract PDF: Purpose
This study compared the clinical and radiological results of the femoral neck system (FNS) and cannulated compression screws (CCS) for the fixation of femoral neck fractures.
Materials and Methods
Patients who underwent FNS or CCS internal fixation for femoral neck fractures between January 2016 and January 2022 were analyzed retrospectively. The hip joint function using the Harris hip score (HHS) was evaluated three months and one year after surgery. The operation time, fracture healing time, and associated surgical complications in the two groups were compared and analyzed statistically.
Results
Seventy-nine patients were categorized into 38 FNS and 41 CCS groups. The FNS group had a longer operation time and higher postoperative HHS at three months (p<0.01). Femoral neck shortening was lower in the FNS group (p=0.022). There were no significant differences in the fracture healing time and other complications.
Conclusion
There were no differences in most clinical outcomes and complications between the two groups except for the three-month HHS and femoral neck shortening. This study suggests that FNS could be an alternative to CCS for treating femoral neck fractures.

Huge Pseudoaneurysm of Popliteal Artery Following Conservative Treatment of a Distal Femur Fracture: A Case Report: Won Chul Cho, Chong Bin Park, Young Jun Choi, Hyun Il Lee, Hee Jae Won, Jae Kwang Hwang; J Korean Fract Soc 2016;29(2):137-142. Published online April 30, 2016; DOI: https://doi.org/10.12671/jkfs.2016.29.2.137

Abstract PDF: A pseudoaneurysm is a contained arterial disruption in the intimal and medial layers of an arterial wall. It may originate from a perforation caused by traumatic or iatrogenic injury or the dehiscence of a surgical anastomosis. Because of its insidious onset and delayed presentation, orthopaedic surgeons should be aware of the possibility of such a lesion after an initial trauma. We report on a case of a delayed huge pseudoaneurysm of the popliteal artery that occurred 11 months after conservative treatment of a supracondylar fracture of the femur in order to keep in mind the possibility of the delayed presentation of vascular injury after a distal femur fracture.

Intramedullary Nailing of Distal Tibial Fractures with Percutaneous Reduction by Pointed Reduction Forceps: Jae Kwang Hwang, Chung Hwan Kim, Young Joon Choi, Gi Won Lee, Hyun Il Lee, Tae Kyung Kim; J Korean Fract Soc 2014;27(2):144-150. Published online April 30, 2014; DOI: https://doi.org/10.12671/jkfs.2014.27.2.144

Abstract PDF: PURPOSE
The purpose of this study is to analyze the radiographic and clinical results of intramedullary nailing after percutaneous reduction using pointed reduction forceps for spiral or oblique fractures of the distal tibia. The benefit of percutaneous reduction using pointed reduction forceps in anatomical reduction and maintenance was assessed.
MATERIALS AND METHODS
From January 2005 to December 2009, 47 cases of distal one-third tibial fracture were managed by intramedullary nailing using pointed reduction forceps. Thirty-eight cases were spiral fracture and nine cases were oblique fracture. In all cases, the percutaneous reduction was achieved using pointed reduction forceps under fluoroscopy control. While maintaining the reduction with the pointed reduction forceps, the intramedullary nail was inserted. The pointed reduction forceps were removed after insertion of proximal and distal inter-locking screws. Alignment was evaluated with anterior-posterior and lateral radiographs taken immediately post-operation and at the time of union.
RESULTS
At immediate post-operation, the mean displacement of valgus and anterior angulation was 0.57degrees and 0.24degrees, respectively. That of valgus and anterior angulation at bone union was 0.37degrees and 0.16degrees, respectively. The average duration of bone union was 16.1 weeks.
CONCLUSION
Intramedullary nailing with percutaneous reduction using pointed reduction forceps for distal tibial fractures was an easy and effective method for achievement of accurate alignment intra-operatively. Accurate alignment was successfully maintained until bone union.

Percutaneous Vertebroplasty in the Treatment of Osteoporotic Compression Fracture (99 Patients, 171 Vertebral Bodies): Chung Hwan Kim, Hyung Sun Ahn, Jae Kwang Hwang, Jung Suk Song, Eui Jung Bae; J Korean Fract Soc 2006;19(2):259-264. Published online April 30, 2006; DOI: https://doi.org/10.12671/jkfs.2006.19.2.259

Abstract: PURPOSE
This study was designed to compare the clinical and radiologic outcome of the patients who underwent percutaneous vertebroplasty among the groups based on follow-up period and BMD.
MATERIALS AND METHODS
A total of 99 patients (171 vertebral bodies) underwent percutaneous vertebroplasty from January 2001 to September 2003. The patients were divided into 3 groups by follow-up periods, and also divided into 2 groups by BMD. We investigated the difference of radiologic and clinical effects among the groups. Radiologic findings was assessed as vertebral height restoration rate and rate of reduction loss by measurement of the height of vertebral body. The clinical outcomes were graded into 5. The statistical analysis was done using Chi-squire test and Independent-samples T test.
RESULTS
Among the groups divided by follow-up period, there was no statistically significant difference of clinical and radiologic results except the rate of reduction loss between group I and group III (p>0.05). Between the groups divided by BMD, there was no statistically significant difference of clinical and radiologic results.
CONCLUSION
Percutaneous vertebroplasty with bone cement for the osteoporotic compression fracture is an efficient procedure and considered as technique producing pleasurable clinical and radiologic results regardless of follow up-period and BMD.

Treatment of Thoraco-Lumbar Bursting Fractures According to Load-Sharing Classification: Chung Hwan Kim, Jae Kwang Hwang, Young Joon Choi, Kyoung Hwan Kim, Jeong Suk Song, Jeong Ho Kang; J Korean Fract Soc 2005;18(1):69-75. Published online January 31, 2005; DOI: https://doi.org/10.12671/jkfs.2005.18.1.69

Abstract PDF

PURPOSE
To determine optimal levels of posterior fixation in thoraco-lumbar bursting fractures according to the Load-sharing classification.
MATERIALS AND METHODS
From Aug. 1999 to Aug. 2003, 50 patients who had been operated with the posterior fixation in one-body thoraco-lumbar bursting fracture were selected. They were divided into two groups, group I, 6 points and below in the Load-sharing score and group II, 7 points and above. And also, each groups subdivided into two subgroups, A (short segment fixation including below and above one body) and B (long segment fixation including below and upper two body). So patients subdivided into I-A, I-B, II-A, II-B. Change of the corrected kyphotic angle was measured and compared with each subgroups.
RESULTS
The loss of the corrected kyphotic angle was measured average 1.7degrees in group I and 4.1degrees in group II, and there was significant difference between two groups (p>0.05). The loss of the corrected kyphotic angle in the subgroups was average 1.8degrees in I-A, 1.6degrees in I-B, 3.5degrees in II-A and 4.9degrees in II-B. And there was significant difference statistically in I-A and II-A (p>0.05).
CONCLUSION
In the thoraco-lumbar bursting fracture with 6 points and below of the Load-sharing score, the fixation of the short segment is a useful method. But in the fracture with 7 points and above, the fixation of the short segment is not enough, and these findings be required the further evaluation for some cause of the loss of corrected angle and treatment modalities including the fixation of the long segment.
