Conversion total-hip replacement following previous acetabular fractures

Purpose of review: This review focuses upon the reported results of conversion total-hip replacement (THR) following previous acetabular fractures. Recent findings: Conversion THR remains as an excellent reconstructive option for patients with adverse sequelae following previous acetabular fractures. It is more difficult and has higher complication rate than routine primary THR. The improvement in pain relief and function resembles that of uncomplicated hip replacements. Durability of fixation has continued to improve with newer implant designs and surgical techniques. The principal problem in this high-demand patient population is wear at the articulation with associated osteolysis, which may result in the failure of the THR. Summary: Success of THR using cementless fixation is very good and durable in patients with previous acetabular fractures. Durability remains to be limited by wear, osteolysis, infection, and other complications unrelated to implant fixation.
