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.
