Risk Factors of Periprosthetic Fracture after Total Knee Arthroplasty: Ju Young Shin, Hyung Jun Kim, Seung Han Cha, Dong Heon Kim; J Korean Fract Soc 2012;25(1):1-7. Published online January 31, 2012; DOI: https://doi.org/10.12671/jkfs.2012.25.1.1

Abstract PDF: PURPOSE
To evaluate the incidence rate and risk factors for periprosthetic fracture after total knee replacement (TKR).
MATERIALS AND METHODS
We carried out a retrospective case-control study of 596 patients (951 knees) who underwent TKR between 1999 and 2006 and who were followed up over 36 months. We classified patients into group I (study group) and group II (control group). We subdivided risk factors as pre-operative, intra-operative, and post-operative factors. Age, osteoporosis, revision arthroplasty, CVA, and alcohol dependence were categorized as pre-operative factors; anterior femoral notching and prosthetic types (mobile, fixed, and load-bearing) were considered intra-operative factors; and post-operative activity level was classified as a post-operative factor. We obtained information from the patients' charts, X-ray film, and telephone interviews.
RESULTS
The overall incidence rate was 2.25%; 3 patients were male, and 18 were female (14.28% and 85.72%, respectively). Old age (p<0.01, odds ratio=1.14), osteoporosis (p=0.01, odds ratio=4.74), revision arthroplasty (p=0.01, odds ratio=7.46), CVA (p=0.02, odds ratio=8.55), and alcohol dependence (p=0.03, odds ratio=44.54) were statistically significant among the pre-operative factors. Among the intra-operative factors, anterior femoral notching (p<0.01, odds ratio=11.74) was significant, and continued heavy labor (p<0.01, odds ratio=8.14) was significant among the post-operative factors.
CONCLUSION
We concluded that old age, osteoporosis, revision arthroplasty, comorbidity related with falling down, anterior femoral notching, and continued heavy labor were associated with periprosthetic fracture after TKR.

Treatment of Femur Supracondylar Fracture with Locking Compression Plate: Seong Ho Bae, Seung Han Cha, Jeung Tak Suh; J Korean Fract Soc 2010;23(3):282-288. Published online July 31, 2010; DOI: https://doi.org/10.12671/jkfs.2010.23.3.282

PURPOSE
To evaluate the effectiveness of locking compression plate by analyzing the clinical outcomes of open reduction and internal fixation with locking compression plate in the treatment of femur supracondylar fracture.
MATERIALS AND METHODS
We reviewed 21 cases of distal femur fractures which were treated with locking compression plate in our hospital from February 2005 to March 2009 and followed up for minimal 1 year. The types of fractures were seven A1, four A2, two A3, six C2, and two C3 according to AO classification. 2 cases were open fractures. The cases were evaluated by the criteria of Schatzker-Lambert.
RESULTS
The mean time to union was 14.3 weeks. One delayed union, one refracture were observed, but no nonunion and postoperative infection was observed. The outcomes were excellent in 6 cases, good in 11, fair in 3, and failure in 1 by the criteria of Schatzker-Lambert. The overall results were excellent or good in 17 cases (81.0%).
CONCLUSION
In the treatment of femur supracondylar fracture, open reduction and internal fixation with locking compression plate yields good result and locking compression plate is useful choice of fixation option.

Bilateral Malunion and Distal Radioulnar Joint Dislocation after Operative Treatment of Bilateral Galeazzi Fractures in Child: A Case Report: Sang Jin Cheon, Dong Joon Kang, Nam Hoon Moon, Seung Han Cha, He Myung Cho; J Korean Fract Soc 2009;22(4):292-296. Published online October 31, 2009; DOI: https://doi.org/10.12671/jkfs.2009.22.4.292

Abstract PDF: Galeazzi fractures in child is rare and seldom necessary of operative treatment because the result of conservative treatment is good. We present the patient who was a 11-year-old male and fell onto his both hands during a hundred-meter dash. His diagnosis was bilateral Galeazzi fractures and limited open reduction and internal fixation with Kirschner pins was initial treatment at local hospital. After 4 weeks postoperatively, Kirschner pins were removed and rehabilitating exercise was started. After 4 months postoperatively, he was transferred to our hospital due to malunion with severe angular deformities and distal radioulnar joint (DRUJ) dislocation. He was treated with corrective osteotomy. Thus, as in this case, we suggest more careful treatment and observation if conservative method of Galeazzi fracture in child is chosen and consider operative method as treatment according to age and pattern of fracture.
