N2 - It has been suggested that stem-cement debonding is likely an event which leads to loosening of a hip prosthesis by cement mantle cracking around the prosthesis. One method being pursued to reduce risk of loosening is to improve stem-cement bonding. A different approach is to design a prosthesis to take advantage of debonding. Such a design is investigated here, a collarless tapered prosthesis that has unique design features, a debonded interface and an unsupported distal tip. The creep behavior of acrylic bone cement, and creep-induced subsidence leading to a mechanical taper-lock are considered as important features of the design. The objective of this work was to define numerically the effects of debond and unsupported distal tip on bone cement.

Revision hip surgery is also performed because of dislocation of the components, subluxation or dislocation of the liner from the acetabular shell, deep infection, surrounding fracture of bone, prosthetic fracture and subsidence of the femoral stem.

Despite stem subsidence being a major complication of femoral impaction bone grafting in cemented revision hip arthroplasty, few studies have distinguished subsidence at the prosthesis-cement interface from that at the cement-bone interface. It is unknown how technique developments intended to improve the procedure influence stability of the stem.

The median subsidence at 12 months for Series 1, 2, and 3 were 2.1, 0.5, and 0.7 mm at the prosthesis-cement interface and 1.3, 0.1, and 0.1 mm at the cement-bone interface. There were two postoperative Vancouver B periprosthetic fractures in Series 1, four hips were revised for loosening in Series 1, and there were no fractures or loosening in Series 2 and 3 at minimum 2 years’ followup. There were no surviving hips radiographically classified as possibly or probably loose.

Evolution in techniques of femoral impaction grafting in this study were associated with reduced subsidence of the stem at both the prosthesis-cement interface and cement-bone interface when compared to the original series. Concurrent with reduced stem subsidence was the absence of periprosthetic fracture, radiographic loosening, and complications requiring rerevision.
