Acute Periacetabular Osteotomy for Recurrent Posttraumatic Dislocation of the Hip: A Case Report.

Case: A 23-year-old woman with injury-induced acetabular dysplasia developed subacute recurrent dislocation of the right hip following closed reduction of a traumatic dislocation. The initial dislocation had been associated with small posterior wall and femoral head fractures. The recurrent dislocation was addressed with an acute periacetabular osteotomy (PAO) for hip stabilization and femoral head fragment excision.

Conclusion: An acute PAO is an unusual yet viable treatment strategy for addressing recurrent dislocation following traumatic fracture-dislocation in patients with posterior wall deficiency and injury-induced hip dysplasia. In the patient described herein, the procedure resulted in early stability, but she developed posttraumatic osteoarthritis at 1 year and 4 months after the injury.
