Two-year experience using a limited-incision direct lateral approach in total hip arthroplasty.

摘要

We evaluated clinical, radiographic, and short-term recovery outcomes in an 18-month 1 surgeon series of 102 unilateral primary total hip arthroplasties performed by direct lateral approach through standard size (15-20 cm) and limited (<10 cm) incisions. Patients were blinded to incision type. Observed measures related to hematological status, transfusions, operative time, hospitalization time, narcotic use, rehabilitation, and discharge disposition did not appear to differ by incision type. Components were well placed in both groups. Intraoperative femoral fractures occurred in 2 limited-incision cases. At 2 years' minimum follow-up, we did not observe evidence that minimally invasive surgical technique provided clinically significant benefit to these patients.
