胸腔镜辅助下前路减压植骨融合术治疗合并椎间盘损伤的下胸椎椎体爆裂骨折

 目的 观察胸腔镜辅助下前路减压植骨融合术治疗合并椎间盘损伤的下胸椎椎体爆裂骨折的疗效。方法 2005年 12月至 2008年 5月, 应用胸腔镜辅助下前路减压植骨融合术治疗合并椎间盘损伤的下胸椎椎体爆裂骨折患者共 11例。男 10例, 女 1例；年龄 17~56岁, 平均 34岁；T12 5例, T11 4例, T10及 T8各 1例。骨折按 AO分型: A2.2型 4例, A3型 7例。脊髓神经功能按 Frankel分级: A级 5例, C级 2例, D级 2例, E级 2例。术后第 1年随访 3次, 分别是 3、6和 12个月, 其后每 12个月随访一次。随访项目包括症状、体征、X线或 CT检查以及 Frankel评分。结果所有患者手术均顺利完成, 手术时间 3.5~8h, 平均(5.2±1.6) h, 术中出血量 600~3800 ml, 平均(1195±576) ml。术后 1例患者出现肋间神经痛, 经对症处理后消失。所有患者均得到随访, 随访时间 36~65个月, 平均(49.5±5.9)个月。 24个月随访时摄 CT片均证实植骨已获得骨性融合。随访期内无其他并发症发生。末次随访时, Frankel分级: A级 5例, D级 2例, E级 4例。结论胸腔镜辅助下前路减压植骨融合术是治疗合并椎间盘损伤的下胸椎椎体爆裂骨折的有效方法, 但该方法技术要求高, 具有较长的学习曲线。

Anterior decompression and autograft fusion under video-assisted thoraco-scopic to treat lower thoracic vertebrae bursting fracture complicated with intervertebral disc injury

Objective To study the effect of anterior decompression and autograft fusion under video-assisted thoracoscopic to treat lower thoracic vertebrae bursting fracture complicated with intervertebral disc injury.Methods Eleven patients who suffered from lower thoracic vertebrae bursting fracture complicated with intervertebral disc injury were treated with anterior decompression and autograft fusion under video-assisted thoracoscopic from December 2005 to May 2008.The involved vertebrae included T12 in 5cases,T11 in 4 cases,T10 in 1 case and Ts in 1 case.According to the AO classification,4 patients were A2.2and 7 were A3.According to the Frankel classification,5 patients were rated as grade A,2 as grade C,2 as grade D and 2 as grade E.Results Every patient underwent successful operation.The operation time was 3.5-8 h(average,5.2±1.6).The blood loss was 600-3800 ml(average,1195±576).One patient got intercostal neuralgia after operation,which disappeared after treating with analgesic drugs for 7 days.All patients were followed up for 36-65 months (average,49.5±5.9).All patients got bony fusion according to the CT scans 24month after operation.There were no neurological function deterioration and other instrument complications happened.At the last follow-up,5 patients were rated as grade A,2 as grade D and 4 as grade E,according to the Frankel classification.Conclusion Anterior decompression and autograft fusion under video-assisted thoracoscopic is an effective method to treat lower thoracic vertebrae bursting fracture complicated with intervertebral disc injury.However,this method needs higher technology and has a long study-curve.
