BACKGROUND: Procedure of the femur is extremely challenging during total hip arthroplasty (THA) for Hartofilakidis type C developmental dysplasia of the hip. The main purpose of this study is to compare the clinical effectiveness of proximal femoral reconstruction (PFR) with subtrochanteric transverse osteotomy (STO).
METHODS: Between 2006 and 2015, 33 primary THAs in 26 patients were performed with PFR and 16 hips in 13 patients underwent STO. The mean follow-up was 4.2 (range, 2.2-10.8) years in PFR group and 5.9 (range, 3.5-11.3) years in STO group. At the final follow-up, clinical scores and radiographic results were evaluated for 33 hips in PFR group and 15 hips in STO group.
RESULTS: Postoperative Harris hip scores and implant position did not differ between the treatment groups. The mean length of the oblique osteotomy line at proximal femur was 6.9 cm (range, 5.8-7.6 cm) in PFR group. The amount of bone union occurred within 6 months after surgery was 24 (72.7%) hips in PFR group and 9 (60.0%) in STO group. Three major postoperative complications occurred in PFR group, and medial femoral calcar erosion was noted in 1 hip in STO group.
CONCLUSION: Similar with STO, the clinical results of PFR technique are a reliable solution for femoral procedure during THA in patients with Hartofilakidis type C developmental dysplasia of the hip.
