Extended trochanteric osteotomy (ETO) was known as a useful method to remove
implants and cements during revision surgery. The purpose of this study was to
evaluate the safety and efficacy of using ETO on the treatment of prosthetic hip
infections. We reviewed 23 patients who had undergone two-stage exchange
procedures using ETO for periprosthetic hip infection. Control group was 46 patients
who had undergone revision hip arthroplasty using ETO for aseptic loosening. Study
group consisted of 11 men and 12 women with a mean age of 59 years (33 to79).
Mean follow-up was 49 months (24 to105). Control group consisted of 21 men and
25 women with a mean age of 61 years (34 to88). Mean follow-up was 54 months
(24 to104). Outcome measures were Harris hip score, time to healing of ETO,
femoral component stability, eradication of infection, and postoperative
complications. The mean Harris hip score was improved from 36 points
preoperatively to 82 points postoperatively. Periprosthetic hip infection was
eradicated in 22 (96%) of 23 patient. In all cases, ETO was healed at a mean of 11
weeks. There was no aseptic loosening of femoral component. Complications
included two postoperative femoral fractures, one transient peroneal nerve palsy, and
one dislocation. Postoperative Harris hip scores, time to healing of ETO, femoral
component stability, eradication of infection, and overall complication rates did not
differ between the study and control groups. ETO can be used safely and effectively
as part of two-stage revision procedures for periprosthetic hip infection.
