目的总结采用后路全脊椎切除术治疗儿童脊柱后凸畸形的临床经验、技术要点和疗效。方法回顾性分析2010年7月-2011年8月在重庆医科大学附属儿童医院骨科接受后路一期全椎体切除+重建治疗的10例脊柱后凸畸形患儿的病例资料,其中男3N,女7例,年龄6~15岁,平均11岁,术前脊柱后凸Cobb角76°~112°,平均97.8°。2例术前有神经系统症状,Frankel分级C级l例、D级1例。所有患儿均行后路一期全脊椎切除、经椎弓根固定、植骨融合术。结果所有患儿手术顺利,手术时间240~560min,平均373min;出血量550~2200mi,平均1115ml;术后后凸Cobb角10°~43°,平均29.3°,矫正率70.0%;患儿的躯干和双肩失平衡均得到显著改善,腰背部疼痛有明显缓解;术前有神经系统症状的2例患儿术后Frankel分级均恢复到E级。结论后路全脊椎切除+椎弓根钉.棒系统内固定术矫正儿童脊柱后凸畸形安全有效,并可达到稳定的短节段内固定及优良的融合效果。
Objective To summarize the experience, technique and curative effect of vertebral column resection via posterior approach for kyphotic deformity in children. Methods The clinical data of 10 children (3 males and 7 females; aged 6-15 years with average of 11 years) who suffered from kyphotic deformity and undergone one-stage posterior vertebral column resection and reconstruction from Jul. 2010 to Aug. 2011 were retrospectively analyzed. The pre-operative Cobb angle of kyphosis was 76~-112~ with an mean of 97.8~. Nervous system symptoms were found in 2 children, of them one was of Frankel C class and another one was of Frankel D. All the children underwent one-stage posterior vertebral column resection, pedicle fixation combined with bone graft. Results "Ihe operation was successfully in all the patients. The average surgery time was 373rain (240-560min), the intraoperative blood loss was 1115ml (550-2200mi), the average post-operative Cobb angle of kyphosis was 29.3(10~-43~), and the correction rate was 70.0%. The torso and shoulder imbalance in all the 10 children was significantly improved, and dorsolumbar pain was markedly relieved. The Frankel classification of 2 children having preoperative nervous system symptoms were both ameliorated to class E after operation. Conclusions Posterior vertebral column resection with pedicle screw-rod fixation is an effective and safe surgical method for the treatment of kyphotic deformity in children. Satisfactory stability of short segment fixation and bone graft fusion can be accomplished.
