title: Triple pelvic osteotomy for the treatment of residual hip dysplasia. Analysis of complications.
abstract: The aim of the paper was to present the results achieved with triple pelvic osteotomy in the treatment of residual hip dysplasia, with special interest in identifying recurrences and complications and how to avoid them. 60 patients (76 hips) with developmental dysplasia of the hip (DDH), treated by the triple pelvic osteotomy according to Tönnis and modified by Vladimirov, were included in the study. Hips were evaluated radiologically with the center-edge (CE) angle, break of the Shenton-Menard arch and index of acetabular depth by Heyman-Herndon, and functionally using the Harris Hip Score (HHS). The postoperative results showed an average increase of the CE angle by a mean of 23.5+/-9.28 degrees, with a highly significant difference between the preoperative and final postoperative findings (t-test, t=-20.85, p<0.01). The mean HHS significantly improved (p<0.01). Total complication rate was 13,1%, divided in: 1,3% (one case) of triple nonunion of iliac, pubic and ischial bones, 7,9% (six cases) of double nonunion of pubic and ischial bones, 2,6% (two cases) of peroneal palsy and 1,3% (one case) of infection. In this study the triple pelvic osteotomy showed to be reliable for acetabular dysplasia in adolescent and young adult, alone or in association with proximal femoral osteotomy and/or great trochanter distal advancement.
