Dislocation of an S-ROM total hip arthroplasty secondary to traumatic femoral stem dissociation from the metaphyseal sleeve.
Modular total hip arthroplasty component dissociation has been reported. We describe a case of recurrent instability secondary to femoral stem dissociation from the proximal metaphyseal sleeve and resultant traumatic retroversion of the neck. Femoral stem revision was necessary for treatment of this rare complication.
