Background: In total hip arthroplasty (THA) of hips with coxa vara, the femoral stems might be inserted in a varus alignment. To avoid varus insertion, we designed a technique, which we termed "trochantoplasty." In this procedure, the medial half of the greater trochanter was removed during THA. Methods: We evaluated 30 patients (31 hips) who had coxa vara deformity and underwent THA using trochantoplasty at the mean follow-up of 5 years (range, 3-9 years). Results: All stems were inserted in the neutral position. One Vancouver type 1 periprosthetic femoral fracture occurred after a fall at postoperative 2 months. At the latest follow-up, the mean power of abductor was 4.3 (range, 3-5). Four patients had moderate limp whereas 26 patients had slight limp. The abduction at 90 degrees flexion ranged from 15 degrees to 45 degrees (mean, 35 degrees). There was no revision. All prostheses had bone-ingrown stability without any detectable wear or osteolysis. The mean Harris hip score was improved from 66.9 to 89.4 points. Conclusion: Trochantoplasty can be used to avoid varus insertion of the femoral stem while performing THA in patients with coxa vara deformity without compromising the abductor mechanism.
