Two-incision minimally invasive total hip arthroplasty--results and complications

The purpose of this study was to determine the complication rate and functional result after two-incision minimally invasive total hip arthroplasty in a retrospective consecutive case series of the first 45 patients treated by a single surgeon. The mean follow up period was 2.1 years. There were 4 early major complications (2 peri-operative fractures and 2 re-interventions) and 28 early minor complications (1 superficial infection and 27 patients with a loss of sensation of the lateral aspect of the thigh). One stem loosening required revision within two years. The mean modified Harris Hip Score at final follow-up was 91.5. Our experience shows a relatively high complication risk after two-incision minimally invasive total hip arthroplasty, and we have since abandoned this technique.
