Purpose: To evaluate the treatment outcome for Type A2 or above intertrochanteric fractures in elderly patients using cementless bipolar hemiarthroplasties incorporating a standard (tapered, rectangular) stem.
Materials and Methods: We retrospectively reviewed the records of 37 patients who had undergone bipolar hemiarthroplasty between February 2006 and February 2010 in our hospital, and who had received follow up evaluation for more than two years after the surgery. The mean patient age was 73.5 years (range 65-88 years), and 16 patients were male and 21 were female. We evaluated the the results of their treatment by analyzing the operation duration, volume of bleeding, measured results for the recovery of walking capability, and any complications and radiologic findings.
Results: The mean operation duration was 75.3 minutes(50-185 minutes). The average total volume of bleeding was of 755.5 cc(75-1,400 cc). Upon the final follow-up visit, 27 patients(72.9%) had recovered more than 80% of their pre-injury Barthel index values(72.8±15.1). Complications included one case of deep infection, one case of acetabular erosion, and 3 cases of greater trochanter non-union. There were no cases of revisions due to prosthesis loosening or for other reasons.
Conclusion: Cementless bipolar hemiarthroplasty using a tapered, rectangular stem is a viable alternative treatment for type A2 intertrochanteric fractures in elderly patients which supports rapid patient mobilization ability.
