-
This review article presents a comprehensive literature review regarding extended trochanteric osteotomy (ETO).
-
The history, rationale, biomechanical considerations as well as indications are discussed.
-
The outcomes and complications as reported in the literature are presented, discussed and compared with our own practice.
-
Based on the available evidence, we present our preferred technique for performing ETO, its fixation, as well as post-operative rehabilitation.
-
The ETO aids implant removal and enhanced access. Reported union rate of ETO is high. The complications related to ETO are much less frequent than in cases when accidental intra-operative femoral fracture occurred that required fixation.
-
Based on the literature and our own experience we recommend ETO as a useful adjunct in the arsenal of the revision hip specialist.
