Abstract

Reproducible fractures of the posterior acetabular wall were created in ten paired hemipelves from fresh human cadavers. After fracture fixation, the hemipelves were mounted on to a MTS machine and the posterior wall was loaded at a rate of 0.25 mm/s until failure. Failure was defined as a 2-mm displacement at the fracture site or the dislocation of the femoral head from the acetabulum. Results emphasize the importance of appropriate postoperative measures in minimizing the force directed against the posterior wall until the fracture has healed. Secure fixation of posterior wall fractures is critical since loss of fixation results in instability and joint incongruity which limit the options for reconstruction.
