Surgical dislocation of the hip for excision of benign tumours

Surgical dislocation of hip is used to treat a variety of hip conditions. We report our experience of the approach in excision of benign tumours of the hip.

This is a review of the cases presenting with benign tumours to a tertiary care complex hip clinic. Data was collected prospectively. All patients were radiologically investigated before surgery for anatomical detail. Surgical dislocation was carried out by the senior surgeon in all cases. Non-Arthritic Young Hip Scores were done preoperatively and at 12 months. All patients are under annual follow-up.

There were 9 cases of benign tumours in this series including Pigmented Villonodular Synovitis (2), synovial chondromatosis (2), fibrous dysplasia (2), osteochondroma (2) and chondroblastoma (1). No recurrences, trochanteric nonunion or avascular necrosis have been seen up to a minimum of 18 months follow-up. Non-arthritic Young Hip scores improved from a mean of 45 to 89 at 12 months.

Surgical dislocation of the hip is a useful approach for removal of benign tumours of the hip joint.
