Salter's innominate osteotomy: The biologic stimulating effect

This study entails the follow-up of 28 patients (33 hips) with congenital h ip dislocation. The primary treatment was one-stage open reduction and Salt er type osteotomy. The mean follow-up period was 5 years and 6 months (rang e = 3 years to 7 years 4 months). At last follow-up, 9 hips (27%) were clas sified as excellent, 22 hips (67%) as good, and 2 hips (6%) as fair. Avascu lar necrosis developed in two hips (6%) postoperatively. The difference bet ween the acetabular index at immediate postoperative time and at last follo w-up was statistically significant (p < 0.01). The Salter osteotomy by itse lf may have a biologic stimulating effect on the acetabulum, which accentua tes reversal of the dysplastic changes.
