Abstract
OBJECTIVE: To study the effects of the Spitzy shelf operation on hip pain. METHOD: A modified Spitzy shelf procedure was performed in 60 hips with residual hip dysplasia. The mean age at surgery was 11.7 years (range 5.5-22.4 years). RESULTS: Twenty-one hips had pain preoperatively. One year postoperatively 57 hips (95%) were painless. The mean postoperative painless period in patients with >10 years follow-up was 24.1 years (range 5.0-51.5 years). The only independent predictor of long duration of painlessness was preoperative CE angle ≥10°. CONCLUSION: The Spitzy procedure had favorable short- and long-term effects on hip pain.
