摘要 目的探讨后路半椎体切除,短节段经椎弓根内固定术治疗小儿先天性脊柱侧凸患者的临床效果。方法11例小儿先天性脊柱侧凸患者均为侧后方半椎体畸形,均行后路Ⅰ期半椎体切除,短节段经椎弓根内固定术;完成内固定后将半椎体上下双侧椎板、横突、关节突去皮质,制作植骨床,残存间隙和植骨床,用切除的松质骨植骨结果手术时间平均3.5h,术中出血量平均420ml,输血300~600ml,平均输血量350ml。术后随防6~24个月,术前主弯Cobb角平均38°,术后平均16.5°,末次随访时15°,平均矫正率66.4%,所有患儿躯干平衡良好,末发现失代偿现象,均无神经系统并发症.结论对小儿发展的半椎体畸形,在原发侧凸发展严重或气僖裢侧凸形成结构性侧凸之前,行后路半椎体切除,短节段椎弓根内固定术可直接去除致畸因素,在冠状面和矢状面均可获得良好的矫形,并且可保存脊柱的生长能力和更多的运动节段。
