Comparison of Conventional and Large Diameter Femoral Heads for the Prevention of Hip Dislocation

A Randomized Multi-Centre Controlled Trial of Large Diameter (36/40 mm) Versus Conventional Diameter (32 mm) Femoral Heads for the Prevention of Post Revision Arthroplasty Dislocation

Summary

About ten percent of revision hip replacements will dislocate. Although dislocation is not a life-threatening problem, it is stressful and costly and requires hospitalization to treat. Subjects who have repeated dislocations live with the constant fear of another dislocation. The purpose of this study is to test the effectiveness of a large ball prosthesis in preventing post-surgical dislocation. A large diameter ball has greater freedom of movement before it impinges; therefore, theoretically, it should not dislocate as easily.
