The Use of Extended Trochanteric Osteotomy in 2-Stage Reconstruction of the Hip for Infection.

J Arthroplasty; 34(7): 1470-1475, 2019 Jul.
Artigo em Inglês | MEDLINE | ID: mdl-30905640

BACKGROUND:

The effect of extended trochanteric osteotomy (ETO) with immediate cerclage wire fixation on the scene of chronic periprosthetic joint infection on infection eradication and the osteotomy healing remains unclear.

METHODS:

One hundred seventeen patients who underwent two-stage revision total hip arthroplasty for chronic periprosthetic joint infection were enrolled in the study. The minimum follow-up was 2 years. Of these, 48 patients had underwent ETO and immediate cerclage wire fixation during the first-stage surgery, while 69 did not undergo ETO or any other osteotomy. In addition, 18 patients had underwent ETO in the second-stage reimplantation surgery. Repeated debridement, curative rate of infection, and complications were compared between the 2 groups. Meanwhile, osteotomy healing between the first and second osteotomy were also compared.

RESULTS:

The repeated debridement rate and curative rate of infection were 2.1% and 95.8% in the ETO group, compared with 13.0% and 82.6% in the non-ETO group; there were significant difference between the 2 groups in these parameters (P = .037 and .030, respectively). Meanwhile, osteotomy healing rate was 93.8% in first-stage surgery with infection scene and 100% in second-stage surgery without infection; no significant difference was detected in osteotomy healing rate and time to healing (P = .278 and .803, respectively). The rate of complication was similar in both groups.

CONCLUSIONS:

ETO combined with immediate cerclage wire fixation does not appear to reduce the rate of infection eradication. There was no harmful effect on complication rate and osteotomy healing.
