Dissociation of the modular femoral stem from the metaphyseal sleeve during reduction of a total hip arthroplasty dislocation.
Dissociation of components in a modular total hip arthroplasty system has been described. We describe the case of dissociation at the interface between the femoral stem and the proximal metaphyseal sleeve during attempts to reduce a dislocation. Open reduction was required for successful treatment of this rare complication.
