Short Term Functional Outcome of Transcervical Neck Femur Fracture Managed With Bipolar Hemiarthroplasty

Abstract

Background: Femoral neck fractures are commonly seen in elderly people. Hemiarthroplasty remains the most common modality of treatment with bipolar prosthesis, which claimed to have a lower incidence of complications. Hence the present study was undertaken to evaluate the functional outcome of intracapsular fracture of femoral neck with cemented or uncemented bipolar prosthesis in elderly Indian population. Method: Total 43 elderly patients were enrolled and operated after being put into lateral decubitus position by the lateral approach or posterior approach of Moore. Modied harris hip score (HHS) was used for analysis of functional outcome, X ray for radiological and patients' pain was assessed by VAS scoring and nally all three parameters compiled and analyzed. Results: The mean age of patients was 68.58 years. Majority of patients had Garden grade III (62.79%) and right sided hip fractures (72.09%). Most of the patients were managed using cemented prosthesis (74.41%) with 45mm prostheses (44.18%). On immediate post-operative assessment, 39 of the 43 patients had fair outcome. At 6 and 12 weeks, 36 and 39 patients respectively had good outcome by HHS. At 6-month follow-up, 30 patients had good outcome while 11 patients had excellent outcome and one patient was died. There was signicant decrease in the VAS score till 6-month follow-up. 40 of the 43 patients had a stable stem xation while 3 patients showed signs of unstable xation. Conclusion: Patient with fractures of the femoral neck get more pain free interval and more rapid return to unassisted activity after bipolar hemiarthroplasty with an acceptable complication rate.
