ABSTRACT

Constrained acetabular components are seldomly used for the treatment of recurrent hip prosthesis dislocation. We present the case of a 48 female patient with recurrent hip arthroplasty treated with a constrained total hip replacement. She sustained 3 additional dislocation episodes of the constrained implant before being revised to a standard non-constrained cup. All three dislocations occurred with the femoral head being disengaged from the constrained polyethylene cup. Revision of the literature reveals that this dislocation fashion has been reported in only three previous cases, with a disloged cup or polyethylene insert being the most common presentation.
