Abstract
INTRODUCTION: In the Middle East, severe developmental dysplasia of the hip with subsequent high dislocation is often seen. We assessed the efficiency of total hip replacement (THR) with subtrochanteric shortening femoral osteotomy and trochanteric advancement in this population. METHODS: This prospective study assessed 25 female patients with symptomatic and severe (Crowe IV). Pre- and postoperative Harris hip score (HHS) and Oxford hip score (OHS) were performed alongside assessment of leg length discrepancy (LLD) and the ability to sit in a cross-legged position. RESULTS: The mean HHS and OHS improved pre-operatively at 1 and 10 years, respectively (p-value < 0.001). The mean postoperative LLD was 3 mm (0-8 mm). Functionally, 22/25 patients were able to sit cross-legged. None of the 25 hips underwent revision during this period. CONCLUSION: Total hip replacement with subtrochanteric shortening osteotomy in combination with trochanteric advancement is sufficient for the management of Crowe type IV hips in this population.
