颈前路椎体次全切除术植骨固定方法改良和随访

Improvement of graft fixation method and follow-up in the anteriorcervical subtotal vertebrectomy

目的 改良颈椎椎体次全切除术的植骨固定方法。方法 在 35例颈椎病椎体次全切术中 ,将捆扎的植骨块镶嵌入骨槽后 ,缝合于两侧颈长肌上 ,再紧密缝合前纵韧带和两侧颈长肌加固。术后戴颈硬围领 3个月。结果 术后 1～ 1 5年随访 ,35例患者的临床症状、体征有明显改善。无严重手术并发症和死亡。X线平片检查显示 :植骨块未见脱出和明显移位 ,与椎体骨融合良好。结论 本改良固定方法在颈椎病椎体次全切除术中 ,能防止植骨块脱出和确保植骨融合。

Objective To improve fixation method of bone grafting in the cervical subtotal vertebrectomy. Methods Tied bone graft was inlaid into the trench, then it was sewed to bilateral muscles longus colli, last anterior longitudinal ligament and muscles longus colli were tightly sewed for further stabilization in subtotal vertebrectomy of cervical spondylosis for 35 cases. The cervical collar was worn for 3 months after operation in all patients. Results Clinical symptom and sign in 35 patients improved remarkably at followed up 1 to 1.5 years after operation. There were no serious complications and no mortality. Plain X rays films examinations showed that the protrusion and marked shift did not occur in all of the bone grafts which fused well with the vertebral bodies. Conclusions The bone graft can be prevented from protrusion and can be surely fused by the improved graft fixation method in subtotal vertebrectomy of cervical spondylosis.
