经皮骶髂螺钉内固定治疗骶髂关节脱位

目的 分析经皮骶髂螺钉内固定治疗骶髂关节脱位的临床疗效.方法 对2002年6月-2006年8月16例骶髂关节脱位患者的临床资料进行回顾性分析,其中男10例,女6例;年龄10～58岁,平均34.3岁.所有患者均在C形臂X线机监测下经皮骶髂螺钉内固定.结果 手术时间为30～90 min,平均50.5 min.术后行骨盆正位、侧位、人口位、出口位X线片和CT扫描,螺钉均位于S1、S2椎体内.16例均获得12～36个月(平均18.3个月)随访.14例骨折复位良好,无切口感染,无术中血管神经损伤,无内固定松动及断裂,腰骶及下肢活动、感觉均正常.结论 经皮骶髂螺钉内固定治疗骶髂关节脱位具有固定可靠、手术创伤小、并发症少、有利于患者康复等优点,是治疗骶髂关节脱位的一种安全、有效的治疗方法.术中需行骨盆正位、侧位、人口位和出口位的透视以保证螺钉置人的准确性.

Treatment of sacroiliac joint dislocation with percutaneous sacroiliac screw internal fixation

Objective To analyze the clinical effect of percutaneous sacroiliac screw internal fixation in treatment of sacroiliac joint dislocation. Methods From June 2002 to August 2006,16 patients with sacroiliac joint dislocation were treated with percutaneous sacroiliac screw internal fixation under C-arm X-ray tomography.There were 10 males and 6 females at age range of 10-58 years(mean 34.3 years).Results The operation lasted for 30-90 minutes(average 50.5 minutes).All patients were followed up for 12-36 months(average 18.3 months).The results of postoperative normotopia,lateral,ingate and egress Xray and CT scanning showed that all the screws were located within S1 and S2 of all,14 patients obtained satisfactory result of reduction,with no infection,nerve injuries,loosening or breakage of the screw fixation.The function and the sensation of the sacroiliac ioint and low extremities recovered to normal. Conclusions Percutaneous sacroiliac screw intemal fixation is an ideally safe and effective way to treat sacroiliac joint dislocation,for it has many advantages such as minimal invasion,reliable fixation,less complication and quick recovery.It is also very necessary to take caudad and cephalad view under an image intensifier during the operation to assure the accuracy of implantation.
