第三代脊柱内固定系统在成人脊柱侧凸中应用的疗效评价

目的回顾分析TSRH、CD、ISOLA等第三代脊柱内固定系统在成人脊柱侧凸矫治中的应用并评价其疗效。方法1999年7月至2003年1月间运用TSRH、CD、ISOLA脊柱内固定系统治疗的35例成人脊柱侧凸患者,包括成人特发性脊柱侧凸及退变性脊柱侧凸。术前冠状面主弯Cobb角平均58 1°(42°~95°),采用前后路联合矫形或单纯后路矫形手术方法。平均随访20个月(10 ~48个月)。通过影像学资料对术前术后冠状面和矢状面的矫形效果对比分析并通过C7 椎体中点距骶骨中心垂线(CVSL)的距离来分析躯干平衡的重建,通过关于自我评估的问卷调查来获得患者主观治疗效果评价。结果所有患者术后外观矫形效果明显。总体冠状面主弯平均Cobb角矫正53 2%。末次随访冠状面Cobb角平均丢失4 3°。C7 中点距CVSL由术前的平均2 6cm矫正为术后的0 24cm。通过随访期间的问卷调查, 89 3%的患者对手术表示满意。2例术后气胸、血胸, 3例术后随访1年后仍主诉腰背部疼痛,其中2例为临近节段退变, 1例为假关节形成。结论对于成人脊柱侧凸,第三代脊柱内固定系统能得到冠状面上较高的矫正率、重建躯干平衡,并且可以获得患者较高的满意度,并发症较少。

The efficacy of third-generation instrumentation for the treatment of adult scoliosis

OBJECTIVE: To evaluate the efficacy of third generation spinal instrumentation such as TSRH, CD and ISOLA for the treatment of adult scoliosis. METHODS: Thirty-five adult scoliosis patients including adult idiopathic and degenerative scoliosis were all surgically treated with third generation instrumentation such as TSRH, CD and ISOLA from July 1999 to January 2003. Preoperative mean cobb angles of major curves of the frontal plane was 58.1 degrees (42 degrees -95 degrees ). The patients received anterior combined with posterior correction or single posterior procedure. Mean follow-up was 20 months (10 - 48 months). Preoperative and postoperative Cobb angles of the frontal plane and sagittal plane and distance between C(7) and CVSL were measured. We assessed the subjective efficacy by questionnaire. RESULTS: Clinical appearance of all patients improved significantly. Mean correction of major curves of the coronal plane was 53.2%. Mean lost of correction of the coronal plane in the last follow-up was 4.3 degrees , distance between the midline of C(7) and CVSL was corrected from 2.6 cm to 0.24 cm. Questionnaire in the follow-up showed that 89.3% patients were satisfied with operation results. Two cases occurred pneumatothorax and haematothorax. Three cases still complained about low back pain in 1 year after operation, among which 2 were adjacent degeneration and 1 was pseudarthrosis. CONCLUSION: Imageology assessment and patients self-evaluation shows that the third generation instrumentation could gain good correction and trunk balance in the treatment for adult scoliosis. And patients are more satisfied and have less complications.
