摘要
目的：探讨小切口减压结合经皮椎弓根螺钉内固定治疗伴神经功能损害胸腰椎骨折的安全性及有效性。方法：2010年12月～2013年10月对18例伴神经功能损害的胸腰椎骨折患者在全麻下行经皮椎弓根螺钉置入、后正中小切口进行神经减压、椎间植骨融合、骨折复位固定术，并加装横连接（微创手术组）。其中男12例，女6例；年龄30-58岁，平均42-8岁；T123例，L16例，L24例．L35例；AO分型A3型3例，C1型14例，C2型2例；神经功能Frankel分级A级5例，B级9例，C级2例，D级2例。记录肌肉剥离切口长度、手术时间、术中出血量、术后引流量、术后伤口疼痛程度和镇痛药物使用情况及减压等并与同期20例传统开放手术患者（开放手术组）情况比较。结果：微创手术组肌肉剥离长度为6．9±1．2cm，术中出血量为538．3±188．7ml，术后引流量为116．4±55．0ml，术后伤口疼痛VAS评分为2．5±1．4分，术后镇痛药物使用比例为16．7％；开放手术组分别为18．6±2．8cm．735．8±252．2ml，233．5±95．8ml，4．4±1．8分和70．0％，两组比较差异均有统计学意义（P〈0．05或P〈0．01）。两组均无手术并发症发生，椎管得到有效减压。两组均获得最少6个月以上随访，两组不完全瘫患者术后均获得1级及以上神经功能恢复。结论：后正中小切口减压结合经皮椎弓根螺钉内固定术在确保良好神经减压的同时能够明显减少手术创伤，且能安放横连接，是治疗伴神经功能损害胸腰椎骨折安全、有效、微创的手术方法。
Objectives： To determine the safety and efficacy of posterior mini-open technique combined with percutaneous pediele screw instrumentation for thoraeolumbar fracture complicated with neurological deficits. Methods： A retrospective review was performed on 18 patients（12 males and 6 females） with thoracolumbar fracture eompfieated with neurological deficits between December 2010 and October 2013. The patients were from 30 years to 58 years with an average of 42.8 years. After general anesthesia, ZINATM percutaneous pedicle screws were implanted above and below the injured segment, neural tissue decompression, interbody fusion with autografl, and reduction was performed under posterior mini-open approach（MISS group）. Compared with the other 20 cases undergoing traditional open surgery （TOS group）, the length of soft tissue dissection, the blood loss during surgery, the drainages, the visual analog score（VAS） of incision and analgesics usage after surgery were evaluated separately. Results： Compared with TOS group, the length of soft tissue dissection was 6.9±1.2cm vs, 18.6±2.8cm, the blood loss during surgery was 538.3±188.7ml vs. 735.8±252.2ml, the drainage was 116.4±55.0ml vs. 233.5±95.8ml, the visual analog score（VAS） of incision was 2.5±1.4 vs. 4.4±1.8 and analgesics usage after surgery was 16.7% vs. 70.0%. All showed significant differences between two groups（P〈 0.05 or P〈0.01）. No surgery related complains were found. All patients achieved effective decompression. In two groups, more than 6 months were followed up, and more than one grade of neurofunetion recovery was observed at final follow-up. Conclusions： Posterior mini-open technique combined with percutaneous pedicle screw instrumentation provides a safe, effective and less invasive alternative for dealing thoracolumbar fracture complicated with neurological deficits.
