髂前下棘椎弓根钉棒内固定技术在骨盆骨折中的应用

目的 :探讨应用髂前下棘椎弓根钉棒内固定技术(supra acetabular spinal pedicle screws and a subcutaneous connecting rod,INFIX)在骨盆前环骨折治疗中的临床应用效果。方法 :2013年12月至2015年1月,采用INFIX手术内固定治疗12例骨盆环骨折患者,其中男9例,女3例;年龄26~65岁,平均38岁;病程均在2周内。按照Young-Burgess分型,其中LC型5例,VS型3例,APC型4例。术前患者髋部疼痛,活动受限,摄片示骨盆环断裂骨折移位。结果:术后患者伤口愈合佳,无相关并发症。12例患者获随访,时间3~13个月,平均6个月。术后患者髋部疼痛缓解,X线片示骨盆复位满意,骨盆环形态恢复良好。按照Matta标准对骨折复位进行评估,优10例,良2例。结论:INFIX内固定治疗骨盆骨折疗效满意,具有操作简便,损伤小并发症少的特点。

Application of supra-acetabular spinal pedicle screws and a subcutaneous connecting rod (INFIX) of anterior inferior iliac spine in the treatment of pelvic fractures

Objective:To evaluate the clinical application effect of supra-acetabular spinal pedicle screws and a subcutaneous connecting rod (INFIX) for the treatment of pelvic fractures. Methods:From December 2013 to January 2015,12 patients(9 males and 3 females) with unstable pelvic fracture were treated with INFIX. The average age was 38 years old (ranged from 26 to 65 years old). All patients were treated within 2 weeks. According to Young-Burgess classification,5 patients were lateral compression injuries,3 patients were vertical shearing injuries,4 patients were anterior-posterior compression injuries. The patients had hip pain and limitation of motion,the X-rays showed the pelvic ring fracture. Results:All wounds were healed well without complications. Twelve cases were followed up with the mean period of 6 months (ranged from 3 to 13 months). The patients'' hip pain was relieved after operation. The post operation X-rays showed the reduction was good and the pelvic ring shaped well. According to Matta''s standards for fracture reduction,10 cases were excellent,2 were good. Conclusion:For treating pelvic fractures,the INFIX is a convenient method which has many advantages including sound fixation simple operation,minimal invasive,and lower rate of complications.
