ABSTRACT
Background: The management of unstable osteoporotic intertrochantric fractures in elderly is challenging because of difficult anatomical reduction, poor bone quality, and sometimes a need to protect the fracture from stresses of weight bearing. Internal fixation in these cases usually involves prolonged bed rest or limited ambulation, to prevent implant failure secondary to osteoporosis. This might result in higher chances of complications like pulmonary embolism, deep vein thrombosis, pneumonia, and decubitus ulcer. The purpose of this study is to analyze the role of primary hemiarthroplasty in cases of unstable osteoporotic intertrochanteric femur fractures. Materials and Methods: We retrospectively analyzed 37 cases of primary hemiarthroplasty performed for osteoporotic unstable intertrochanteric fractures (AO/OTA type 31-A2.2 and 31-A2.3 and Evans type III or IV fractures). There were 27 females and 10 males with a mean age of 77.1 years (range, 62-89 years). Results: Two patients died due to unrelated cause (myocardial infarction) within 6 months of surgery and remaining 35 patients were followed up to an average of 24.5 months (range,18-39 months). The average surgery time was 71 min (range, 55-88 min) with an average intraoperative blood loss of 350 ml (range, 175-500 ml). Six patients needed blood transfusion postoperatively. The patients walked on an average 3.2 days after surgery (range, 2-8 days). One patient had superficial skin infection and one had bed sore with no other significant postoperative complications. One patient of Alzheimer′s disease refused to walk and had a poor result. A total of 32 out of 35 patients (91%) had excellent to fair functional results and 2 had poor result with respect to the Harris hip score (mean 84.8΁9.72, range 58-97). One patient who had neurological comorbidity refused to walk post operatively and was labeled as failed result. Conclusion: Hemiarthroplasty for unstable osteoporotic intertrochanteric fractures in elderly results in early ambulation and good functional results although further prospective randomized trials are required before reaching to conclusion.
