Long-term data and information indicating whether minimally invasive surgery (MIS) approaches are safe and effective with total\nhip arthroplasty (THA) are lacking. Between 2004 and 2006, 75 patients with alcohol-related osteonecrosis of the femoral head\n(ONFH) who underwent 75 THAs with the two-incision approach were studied. The medical records, radiographic parameters,\nand functional outcomes were collected prospectively. All data were compared with those for matched patients who underwent\na modified Watson-Jones (WJ) approach. THA using the two-incision approach was associated with longer operation time, more\nblood loss, more lateral femoral cutaneous nerve injury, and more periprosthetic femoral fractures (
