Twenty-two consecutive patients with 26 dislocated hips were evaluated for a mean of 7 years after open reduction through a medial adductor approach. Severin classification of grade I or II and center-edge angles greater than 20 degrees were present in 73% of hips and 88% of patients treated between the ages of 5 and 14 months. Avascular necrosis (AVN) with partial head involvement occurred in 15% of hips and correlated positively with increased age at surgery, but did not preclude a satisfactory Severin classification. Best results were obtained in children treated between the ages of 5 and 14 months.
对22例连续患者的26个髋关节进行评估，这些患者均通过内收肌内侧入路进行切开复位，平均随访7年。5至14个月龄接受治疗的髋关节中，73%以及患者中88%的髋关节Severin分级为I级或II级且中心边缘角大于20度。15%的髋关节发生了股骨头部分受累的缺血性坏死（AVN），且与手术时年龄增加呈正相关，但这并不妨碍获得满意的Severin分级。5至14个月龄接受治疗的儿童获得了最佳结果。
