Purpose: To evaluate the results of bipolar hemiarthroplasty using calcar replacement stem for hip fractures in elderly patients.
Material and Methods : Between March 1995 and March 2005, the clinical records on 68 cases more than 75 years old who underwent the bipolar hemiarthroplasty using calcar replacement stem and followed minimum 2 years were reviewed. We evaluated the results by modified Harris hip score, walking ability, activity of daily living, complications, osteoporosis and radiologic findings.
Results:The mean postoperative modified Harris hip score was 88.3 (69∼95) in femoral neck fractures and 83.5 (63∼91) in femoral intertrochanteric fractures. Walking ability was recovered in 82.3% (56 cases) and activity of daily living was achived in 82.3% (56 cases). Complications were thigh pain, infection, femoral stem subsidence, stress shield, dislocation.
Conclusion: We consider bipolar hemiarthroplasty using calcar replacement stem for unstable hip fractures in elderly patients with severe osteoporosis is the useful treatment in view of the stable and rigid fixation, early ambulation and the low rate of complications, even if the operation is technically very difficult.
