Abstract: | Minimally invasive osteosynthesis is a well-recognized treatment; however, those of arthroplasty or hemiarthroplasty may rarely be performed. We reviewed the comparison of a mini-incision approach in hemiarthroplasty versus that of an ordinary approach in patients with femoral neck fractures. Two different operative procedures were compared. Thirty-two patients (group 1) had a mini-incision in hemiarthroplasty. Thirty-two patients (group 2) were treated with the conventional approach. The postoperative treatment course was the same for both groups. The mean length of follow-up was 25 months. The results were excellent or good in 86% of the patients (50 of 64) and were equally good for both procedures. However, the full weight bearing term was significantly shortened for patients treated by the mini-incision procedure. Good and excellent results can be expected from either the mini-incision or the ordinary approach in hemiarthroplasty. Only full weight bearing term was significantly short following the mini-incision. This approach results in less dissection and facilitates rapid patient recovery and possibility earlier discharge from the hospital. |
