The role of cemented sockets in 2004

Cement fixation of the acetabular cup in total hip arthroplasty (THA) has evolved through multiple generations of cement technology. Whereas cement technology has produced improvements in cemented femoral fixation, the cemented socket still produces inconsistent results. Even with our current knowledge that cemented cups require exposure of cancellous bone, a clean and dry socket, and adequate bony coverage of the cup, surgeons such as myself are unable to control radiolucency at the bone-cement interface. The technical difficulty of cementing the acetabular cup has led to the increasing prevalence of cementless acetabular cups. Although cementless fixation has resulted in increased incidence of osteolysis, the surgical procedure is less technically demanding, and the long-term mechanical fixation results have been more consistent. Given the experiential learning curve that most orthopedic surgeons face with cemented fixation of the acetabular cup component, the role of the cemented socket in THA today is limited.
