Component dissociation after closed reduction of dual mobility sockets - a report of three cases

Hip Int. Mar-Apr 2011;21(2):263-6. doi: 10.5301/HIP.2011.6529. Epub 2011 Apr 6.


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.
