Dual mobility sockets have been introduced in recent years to manage cases of potential instability after hip arthroplasty, and their use is increasing in revision surgery. We present 3 cases of intra-prosthetic dissociation between the outer polyethylene liner and the femoral head after closed reduction of prosthetic dislocation.
