摘要
目的探讨C型臂透视计算机辅助手术导航系统对于老年人腰椎椎弓根螺钉置入术的影响。方法对286例65岁及以上行腰椎后路减压内固定的腰椎退行性疾病患者分为导航（153例）和未导航（133例）两组，比较两组患者的术中失血量、手术时间和术后下地时间。应用Oswestry功能障碍指数问卷表（0DI）对所有患者的术前和末次随访评分，计算2次评分的ODI评分改善率。结果导航组与未导航组相比，椎弓根手术时间[（27．6士6．3）min、（33．8±9．9）min]和出血量[（135．7±21．1）ml、（165．4±32．1）mid减少，术后下地时间[（134．6±12．3）h、（169．0±23．9）h]缩短；ODI评分改善率[（76．6±3．7）％、（69．8±6．6）％]提高。结论c型臂透视计算机辅助手术导航系统能提高老年腰椎椎弓根螺钉置入术疗效。
Objective To investigate the influence of C arm X-ray perspective computer auxiliary surgery navigation system on lumbar vertebral pedicle screw fixation in the elderly. Methods 286 patients（aged≥65 years） treated by lumbar spine post decompress and pedicle screw fixation for lumbar vertebral degeneration were divided into navigation（n = 153） or non-navigation （n=133） groups. The amount of blood loss, surgery duration and time of beginning to walk after surgery were measured and compared, the improvement grading was determined by Oswestry disability index （ODI） before surgery and at the last follow-up. Results The surgery duration （（27.64±6.3）min vs. （33.8±9.9）min], the volume of blood loss（（135.7±21.1）ml vs. （165.4±32.1）ml] and the time of beginning to walk after surgery（（134.6±12.3）h vs. （169.0±23.9）h3 were obviously reduced in navigation group as compared with non-navigation group （P 〈 0.05）. The grading improvement rate by ODI（（76.64-3.7）%.lows. （69.8± 6.6）%] was higher in navigation group than in non-navigation group （P〈0.05）. Conclusions Using C arm X-ray perspective computer auxiliary surgery navigation system to lumbar pedicle screws fixation is helpful in the elderly for imDroving clinical effieacv.
