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.
本研究评估了Salter髋臼截骨术治疗发育不良、半脱位或先天性髋关节脱位的中期临床和影像学结果。对33例患者的35髋进行随访，手术时平均年龄为4岁7个月，平均随访16.5年。评估了Wiberg中心边缘角、髋臼指数和股骨头的规整性。根据Severin分类，15髋（43%）属于I组，11髋（31%）属于II组，6髋（17%）属于III组，3髋（9%）属于IV组。在术前和近期的中心边缘角（优秀和良好组平均分别为1.1°和28.8°，一般和差组分别为-5.3°和15.0°）以及股骨头的规整性（非常不规整与其他情况）方面发现了显著差异。目前的结果表明，中期随访后，Salter髋臼截骨术是一种有效的治疗方法。作者得出结论，该手术适用于符合Salter提出标准的患者。
