摘　　要：目的探讨后路椎弓根钉棒内固定技术治疗脊柱侧弯后路矫形的效果。方法对9例脊柱侧弯患者(青少年特发性脊柱侧弯7例,先天性脊柱侧弯2例)行一期后路椎弓根钉棒系统矫形内固定术。术前Cobbs角48°～68°;矢状面上胸段(T4～11)后凸9°～17°,胸腰段(T11～L1)前凸3°～7°,腰段(L1～5)前凸19°～23°。结果无死亡、感染及神经系统并发症,未发生术中骨折及脊膜、胸膜损伤。手术时间120～180 min;出血量300～800 ml。术后Cobbs角20°～30°,矫正率为63%。9例均获随访,时间20～30个月。患者均获得骨性融合,无额状面或矢状面失偿。结论后路椎弓根钉棒内固定技术矫形效果明显、有操作简便、内固定牢固的优点,可取得满意的矫形及固定效果。Objective To evaluate the surgical techniques and its clinical results of screw-rod system in the treatment of scoliosis. Methods Nine patients with seoliosis instrumented with pediele screw-rod system were recruited for this retrospective study. The etiological classification of seoliosis was idiopathic for 7, congenital for 2. Cobbs angle was 48°-68° ; kyphosis was 9°- 17° in T4.11 ,lordosis was 3°-7° in T11- L1 , and 19°-23° in L1-5. Results There was no death, no infection and no neurological complication. No intraoperative fracture, no dura matter or pleura laceration occurred. The duration of follow-up ranged 20 - 30 months. Surgical time ranged 120 - 180 rain and mean EBL was 300 - 800 ml. Cobbs angle was 20°- 30°, with 63% correction. Bony fusions were achieved in all patients and no coronal or sagittal plane decompensation occurred. Conclusions The clinical resuhs of screw-rod system are as good as the other implants. Its advantage lies in lower profile, solid inter-locking, versatile implants and handy manipulation. It can get satisfactory orthopedic and fixation effective.
