Abstract
INTRODUCTION: The purpose of this study is to evaluate the clinical and radiographic result in patients who got salvage treatment for the failed fixation of intertrochanteric fracture and to evaluate the factors that may affect healing of these treatment. PATIENTS AND METHODS: Between 1997 and 2016, 39 patients who could be followed up for more than 1 year after treatment were enrolled. For determining of factor that may affect healing of treatment, the primary outcome was based on union. There were success group which achieved a restored union and failure group which had an additional revisional surgery because of another complication for analysis. And neck-shaft angle (NSA) was measured with a goniometer. RESULTS: Fracture healing as a primary outcome (after revision surgery) was achieved 31 out of 39 patients (80%). There were no statistically significant differences between two groups in terms of age, sex, BMI and laterality. In the clinical outcomes, four categories of outcomes were compared between the success and failure groups and significant improvements were observed. In measurements at final follow-up, it the angle was 133.4° in the success group and 123.4° in the failure group. CONCLUSION: The clinical and radiographic results of the salvage treatment for the failed fixation of intertrochanteric fracture were satisfactory in our study. Restoration of femoral neck-shaft angle of failed intertrochanteric fracture is key factors for obtaining successful results.
