title: Posterior allograft bone-block for recurrent dislocation of the hip after hemiarthroplasty in noncompliant patients with neuromuscular disease.
abstract: Two mentally retarded patients with cerebral palsy developed recurrent dislocation of the hip after hemiarthroplasty. Instability had persisted despite release of contracted soft tissues, conversion to a bipolar arthroplasty, and cast immobilization in one patient and repeated closed reductions with abduction splinting and bed rest in the other. Both patients were treated with a posterior femoral head allograft bone-block that resulted in restoration of hip function and control of recurrent dislocations.
