title: A modified two-incision minimally invasive total hip arthroplasty: technique and short-term results.
abstract: Between 2003 and 2005, a total of 425 consecutive cases with a modified two-incision minimally invasive total hip arthroplasty (THA) were performed at our hospital. We analysed 225 cas-es with greater than 12 months follow-up clinically and radiographically. The mean operative time was 70 minutes. Patients could walk on crutches at 1.5 days and discontinued crutch use at an average of 3 weeks. Patients were able to walk upstairs without support at 4 weeks. Radiographic analysis showed the mean lateral opening angle and anteversion of the acetabular components were 43.0 and 17.3, and 97% of the femoral stems were in neutral alignment. There was no radiographic evidence of component migration or subsidence at the most recent follow-up. Therefore, from these early results, a modified two-incision THA was found to be an excellent surgical modality, which allows early rehabilitation and does not increase complications when compared to other MIS two-incision THA techniques.
