目的探讨新生儿急性化脓性髋关节炎后遗病理性脱位的防治措施。方法对 38例中 20例作临床系统性回顾。 20例均行切开复位，其中还同时行大转子下移术 13例，大、小转子关节成形术 2例。 14例行髋臼重建术。结果术后近期复位成功率达 90％，但获中心性复位仅 38.8％。经 6个月～ 12年随访，多数病例疗效满意，髋关节无疼痛，稳定性增加，活动度也逐渐加大。部分头颈吸收破坏者疗效不尽人意，表现为短肢畸形、活动受限甚至纤维强直，并有半脱位、脱位各 1例。结论以大转子下移术为主的联合手术对重塑股骨头和髋臼、促进复位、保持复位后的稳定性具有很大作用，对头臼结构严重破坏、疗效欠佳的病例除了进一步改善治疗方法外，重视新生儿急性化脓性髋关节炎的早期诊断和早期切开持续引流，是预防病理脱位，减少股骨头颈、髋臼破坏的关键，可从根本上防止此后遗症的发生而提高疗效。 Objective To investigate the prevention and treatment of the pathological dislocation of the postanesthesia of neonatal acute suppurative hysteritis. Methods Twenty cases of 38 cases were reviewed retrospectively. Twenty patients underwent open reduction and reduction. Among them, 13 cases were treated with descending major trochanter, and 2 cases were treated with arthroplasty with large and small rotors. 14 cases of acetabular reconstruction. Results The successful rate of immediate postoperative resection was 90%, but only 38.8% of patients received central reduction. After 6 months to 12 years of follow-up, the majority of patients with satisfactory results, no pain in the hip, increased stability, activity gradually increased. Part of the head and neck absorption destroyers less than satisfactory results, manifested as short limb deformity, limited mobility and even fibrosis, and subluxation, dislocation in 1 case. CONCLUSION: The combined surgery, which mainly involves the treatment of greater trochanter, plays a significant role in reshaping the femoral head and acetabulum, promoting the reduction and maintaining the stability after the reduction. In addition to further improving the treatment of severe dislocation of the acetabular structure and poor efficacy, Method, emphasis on neonatal acute suppurative arthritis of the early diagnosis and early drainage of continuous drainage, is to prevent pathological dislocation and reduce femoral head and neck, acetabular destruction of the key to fundamentally prevent the occurrence of this sequelae and improve efficacy.
