Extended trochanteric osteotomy for 2-stage revision of infected total hip arthroplasty.

Abstract

We evaluate the rate of osteotomy healing, implant stability, and eradication of infection when an extended trochanteric osteotomy, with interval placement of an antibiotic-impregnated cement spacer and delayed osteotomy fixation, is used to treat the chronically infected total hip arthroplasty. Thirteen cases were followed for a minimum of 2 years. All patients had complete healing of the extended trochanteric osteotomy within 6 months. At an average follow-up of 39 months, recurrent infection occurred in 3 (23%) patients. Femoral component subsidence of 5 mm occurred in 2 patients, both of which had recurrent infection. Extended trochanteric osteotomy with interval placement of an articulating antibiotic-impregnated cement spacer and delayed osteotomy fixation permits reliable healing of the osteotomy.
