Recurrent anterior hip instability after a simple hip dislocation: a case report.
A 35-year-old woman sustained a simple anterior hip dislocation after a fall. Initial treatment involved a closed reduction under sedation with brace immobilization. Nine months after the initial dislocation, she began having recurrent anterior hip instability (four events) requiring closed reduction under anesthesia. Secondary to the recurrent dislocations, she had a derotational subtrochanteric femoral osteotomy at an outside hospital for the anterior instability. After this procedure she sustained five additional anterior dislocations requiring closed reduction under anesthesia. After nine anterior dislocations, she had periacetabular osteotomy retroverting her acetabulum with repair of the anterior hip capsule which has successfully solved the recurrent instability. To the author's knowledge this is the first reported case of recurrent anterior hip instability treated successfully with a periacetabular osteotomy.
