One surgeon's experience with the 2-incision technique for total hip arthroplasty.

Abstract

This study's purpose was to analyze the complications that occurred during and after one surgeon's first 200 two-incision total hip arthroplasties. Complications included 4 intraoperative femur fractures, 4 postoperative femur fractures, 2 nondisplaced greater trochanter fractures greater than 2 cm, 14 asymptomatic greater trochanter fractures 2 cm or less, 1 malpositioned cup requiring revision, 1 loose stem, 7 cases of heterotopic ossification of grade 2 or higher, 4 dislocations, 1 superficial infection, 80 lateral femoral cutaneous nerve neuropraxias (78 resolved within 6 weeks), and 4 femoral nerve neuropraxias (3 resolved within 12 weeks). This study shows that the 2-incision technique can be performed with a low risk of major complications, and patients can expect reduced tissue trauma and faster rehabilitation. When carefully sought out, minor complications were not uncommon after 2-incision total hip arthroplasty.
