Application of self-made iliac puncture guide in severe and rigid scoliosis with Halo pelvic traction / 西安交通大学学报(医学版)

ABSTRACT

【Objective】 To evaluate the accuracy and safety of self-made iliac puncture guide in severe and rigid scoliosis （SRS） with Halo pelvic traction. 【Methods】 From January 2015 to May 2021， 22 patients with SRS were treated by the Halo pelvic traction. There were 9 males and 13 females， aged 14 to 28 years with an average of 17.6 years； cobb angle was 90° to 140° with an average of （108.80±13.42）°. According to the different methods of iliac puncture， they were divided into guide group （10 patients） in which the self-made guide device was used for iliac puncture and unarmed group （12 patients） in which the needle was punctured through the iliac bone with bare hands. One iliac needle was inserted into each iliac bone of each patient， and the total number of needles in this study was 44. The puncture times， deviation distance， operation time， degree of soft tissue injury， postoperative hospital stay and complications were compared and analyzed. 【Results】 There was no significant difference in age， gender， body mass， or cobb angle between the two groups. In the guide group the average puncture times was （2.50±0.55）， the offset distance was （0.50±0.07） cm， the operation time was （30.50±4.46） min， soft tissue injury was grade （1.83±0.75）， and postoperative hospital stay was （4.33±0.82） d. In the unarmed group the average puncture times was （4.00±0.76）， the offset distance was （2.30±1.20） cm， the operation time was （60.13±26.35） min， soft tissue injury was grade （3.38±1.19）， and postoperative hospital stay was （8.88±3.14）d. There were 2 cases of needle tract infection in both groups respectively. In the unarmed group， there were 2 cases of skin necrosis and 1 case of neurovascular injury. 【Conclusion】 The self-made iliac puncture guide in SRS with Halo pelvic traction can reduce the number of punctures， offset distance， shorten operation time， postoperative hospital stay and complications.
