title: Middle-term results of Salter innominate osteotomy.
abstract: This study evaluated middle-term clinical and radiographic results of Salter innominate osteotomy for treatment of dysplastic, subluxated, or congenitally dislocated hips. Thirty-five hips in 33 patients with a mean age at index surgery of 4 years 7 months were followed up for an average of 16.5 years. Radiographic center-edge angle of Wiberg, acetabular index, and regularity of the femoral head were evaluated. Fifteen (43%) hips were in Group I, 11 (31%) hips were in Group II, six (17%) hips were in Group III, and three (9%) hips were in Group IV according to the Severin classification. Significant differences were found in the preoperative and recent center-edge angle (average, 1.1 degrees and 28.8 degrees in the excellent and good groups versus -5.3 degrees and 15.0 degrees in the fair and poor groups) and regularity of the femoral head (very irregular versus others). The current results indicate that after middle-term followup, Salter innominate osteotomy is an effective treatment. The authors conclude this procedure is indicated in patients who meet the criteria proposed by Salter.
