Favorable Functional Recovery and Stem Stability after Hip Arthroplasty with a Short Metaphyseal Stem in Elderly Patients with Osteoporotic Femoral Neck Fractures.

摘要: Purpose: Short stems have recently become widely used; however, concerns about the initial secure fixation of a short stem in osteoporotic bone remain. The aim this study was to evaluate short-term clinical and radiological results using cementless metaphyseal stabilizing tapered for senile femoral neck fractures. Materials Methods: Thirty-eight arthroplasties (31 bipolar hemiarthroplasties 7 total hip arthroplasties) were performed fractures patients older than 65 years (10 males 28 females). mean age 76.1 follow-up 2.9 years. We retrospectively evaluated results, focusing on walking performance, thigh pain, radiologic with special regard signs stability osteointegration. Results: Mean Harris score 84.3 points 68.4% regained their preoperative performance. No complained pain. osteolysis or loosening observed during follow-up, all but 1 showed stable ingrowth. Conclusion: Short, could be reliable treatment option fractures.
