Osteolysis of the pelvis is a common complication associated with total hip arthroplasty. Osteolysis affects sockets with and without cement, and has been attributed to the biologic reaction to wear debris. With well-fixed cementless sockets, an expansile pattern of osteolysis is usually seen. The radiographic appearance has a radiolucent area that starts at the implant-bone interface and expands into the cancellous bone away from the implant. This pattern of osteolysis can be explained with the concept of effective joint space. This concept states that joint fluid and wear particles will flow according to pressure gradients and follow the path of least resistance. The Level 5 review article by Chiang discusses osteolysis in further depth.
