Total hip arthroplasty in developmental dysplasia of the hip: Review of anatomy, techniques and outcomes.
Total hip arthroplasty (THA) in developmental dysplasia of the hip (DDH) presents many challenges to the reconstructive surgeon. The complex femoral and acetabular anatomy makes standard reconstruction technically challenging. Acetabular coverage can be improved by medialization of the component or augmentation of the deficient areas with bone graft. Femoral shortening osteotomies are considered in cases of severe dysplasia and frankly dislocated hips. Each patient's unique anatomy dictates what options of reconstruction are available. The functional outcomes of THA in DDH are generally excellent, though higher rates of mechanical failure have been reported in this group. This article reviews the anatomy, classification, technical considerations, and outcomes of THA in patients with DDH.
