The Dysplastic Hip: Not for the Shallow Surgeon

Patients who have hip dysplasia are often young and active. Hence, total hip replacement in this group needs meticulous planning to obtain satisfactory fixation with good long-term outcome. Acetabular reconstruction is often complex because of acetabular bone deficiency. Various techniques to deal with the deficiency of acetabular bone stock have been described, including cemented and cementless cups with or without bone graft, impaction bone grafting, perforating the medial acetabular wall (the cotyloplasty technique), and a small-diameter cup at elevated hip center. Multiple studies have reported long-term results of various techniques for acetabular reconstruction.
