[Cup dissociation after reduction of a dislocated hip hemiarthroplasty].

Abstract

Anesthesia should be considered as necessary for prosthesis bipolar hemiarthroplasties dislocation treatment. The authors have moved to a different implant and modified their surgical approach (antero lateral). These modifications were introduced in order to reduce the rate of hip dislocation and above all the event of intraprosthetic dislocation when close reduction was necessary.
