脊柱结核一期内固定治疗重建脊柱稳定性及其矫治后凸畸型的研究
效。而能否在病变的部位直接使用内固定完成重建脊柱的稳定性,从而可以减少二次创伤及手术的危险性呢?20世纪90年代初,国内郑希展等"报道用前路椎体钉治疗41例胸腰椎结核患者,骨融合较单纯椎体间融合为高,术后16个月复查,后凸畸形平均矫正16。左右。Baoachie等l提出在活动性结核病灶内植骨或应用内固定是可行的,具有良好的应用前景,在结核病灶的两端以内固定稳定脊柱,可以直接、有效地维持脊柱的稳定性,防止植骨块骨折、滑脱、塌陷及吸收。本组36例行一期内固定均取得了好的疗效,无植骨块骨折、脱塌陷及吸收,而有效地矫正了后凸畸形,大大地减少了早期并发症及预防了后期脊柱后凸加重和迟发性脊髓、神经症状的发生。3,3手术方法及内固定选择结核发生在c。:部位,可先行后路枕颈融合或c。:的内固定,再行经口腔病灶清除。C,~L3的椎体结核均可采用前路植骨融合内固定。注意内固定的螺钉一定要置于正常的椎体或骨质内,若破坏部位为单个椎间盘及相邻椎体的少部分,内固定也可置于相邻椎体的正常骨质中,这样可减少运动节段不必要的丢失。累及到L4~s-部位的病变,由于其解剖的特殊性,为前路放置内固定装置带来了困难,因此可以选择先行后路内固定,再进行前路病灶清除术。内固定材料以钛合金制作的为好,以利于术后的影像学检查】,判断愈合情况。:结论:彻底的病灶清除联合一期内伺定是提高脊柱结核疗效和后凸矫治的很好方法。4
