Abstract
Total hip replacement in patients with developmental dysplasia of the hip (DDH) is a difficult technical procedure for surgeons to perform because of the potential for these patients to have severe anomalies in their bones and soft tissues.~Introduction~Background~We performed acetabuloplasty in 54 hips from 44 patients by reaming the posterior wall of the native acetabulum and medialising the acetabular component to restore the anatomic centre of hip rotation using a small cup without bone grafting. Median time to post-surgery follow-up was 5 (range 2-14) years.~Materials and Methods~Methods~Prosthetic survival rates in patients after 2 and 5 years post hip replacement were 93% (50/54) and 89% (48/54), respectively. 4 patients required early revision because of malposition and instability of the acetabular cup. 3 patients with Crowe type IV dislocations had transient sciatic nerve palsy and 3 had deep vein thrombosis.~Results~Results~Placement of the acetabular shell using posterior bone stock to provide normal hip rotation is a successful alternative technique for acetabuloplasty in patients with DDH.~Conclusions~Conclusions [ABSTRACT FROM AUTHOR]
