微创后路重建钢板治疗骶髂关节分离

Minimally invasive surgical treatment of sacroiliac joint separation

目的:介绍一种骶髂关节分离的微创治疗方法。方法:采用后路微创重建钢板内固定治疗骶髂关节分离13例,双侧髂后上嵴3㎝切口,用骨盆复位钳复位骶髂关节,经皮插入钢板两端折弯固定于髂后上嵴。术后不辅以其他外固定,第2天起即开始不负重关节功能锻炼。结果:13例均得到随访,随访4～18个月,平均8个月。所有骶髂关节分离均复位良好,伤口甲级愈合。平均临床愈合时间15.3周,Pohlemann骨盆骨折评分:优9例,良4例。结论:微创重建钢板治疗骶髂关节分离是一种有效的方法。

Objective ：To introduce a minimally invaslve surgical method to treat sacroiliac joint separation using close reduction and percutaneous plate osteosynthesis （MIPPO）. Methods： 13 cases of sacroiliac joint separation were treated with MIPPO. All cases were adoptted Bilateral 3 cm incision of posterior superior iliac , resetted by pelvic reset clamp, inserted steel plate bending fixed on both ends. Active and passive motions of hip and knee were allowed 2 days after operation without weight-bearing. Resuhs：All the patients were followed up for 4 to 18 months. The mean time of joint separation union were 15.3 weeks. There was no delayed union, nonunion or malunion in all cases. According to Pohlemann scoring system, the function was optimal 9 and good 4 of all the cases. Conclusion：MIPPO is safe and effective technique in the treatment of sacroiliac ioint separation.
