Pantaloon hip spica cast and constrained liner for the treatment of early total hip dislocation in a young patient with sickle cell disease.

femoral head and subsequent degenerative arthritis of the hip. Pain and ambulatory limitations prompt orthopedic surgeons to consider total hip arthroplasty (THA). In these patients, THA can be challenging secondary to distorted anatomy, prior surgeries, and significant soft-tissue contractures. The case reported here illustrates early prosthetic dislocation after THA in a young patient with sickle cell disease successfully treated with open reduction, conversion to a constrained liner, and 8 weeks in a pantaloon hip spica cast. The authors have obtained the patient’s written informed consent for print and electronic publication of the case report.
