目的 :探讨颈椎病牵引的最佳牵引力 ,牵引角度和牵引时间。方法 :按不同的牵引力及不同牵引角度和时间分别对 5 7例患者进行牵引的同时摄取颈椎侧位片 ,并与牵引前的 X线片进行比较 ,观看拉伸最大长度时所用的牵引力、牵引角度和牵引时间。并结合 2 0 0例患者随机分为两组进行观察研究及 Ridit分析。结果 :在牵引力按体重 5 % ,10 % ,15 % ,2 0 %时 ,颈椎平均分别拉伸了0 .2 1cm ,0 .33cm ,0 .44 cm ,0 .5 6 cm ,当牵引力按体重 2 5 % ,30 % ,40 %时 ,其拉伸长度皆为 0 .5 6 cm ,不再增加 ;并且颈椎的最大应力点也随牵引角度的改变而改变 ;颈椎牵引的耐受时间亦不超过2 0 m in。采用 Ridit分析 ,P<0 .0 5差异有显著性。结论 :颈椎病最佳牵引力为体重的 15 %～ 2 0 % ,牵引角度随病变部位而定 ,牵引时间不超过 2 0 min,符合颈椎生物力学原理。
Objective: To explore the best traction, traction angle and traction time of cervical spondylosis. Methods: According to different traction and different traction angle and time, 57 cases of patients were taken simultaneously while taking the cervical lateral radiographs, and compared with the X-ray before traction to see the maximum length of traction used traction, traction Angle and traction time. And combined 200 patients were randomly divided into two groups for observation and Ridit analysis. Results: At the 5%, 10%, 15%, and 20% of the body weight, the cervical vertebra stretched 0.21 cm, 0.33 cm, 0.44 cm and 0.56 cm on average respectively, 25 5%, 30%, 40%, the tensile length of all 0.56 cm, no longer increase; and cervical maximum stress point also changes with the traction angle changes; cervical traction resistance time nor Over 20 m in. Ridit analysis, P <0. 05 difference was significant. Conclusion: The best traction of cervical spondylosis is 15% ~ 20% of body weight. The traction angle depends on the site of the lesion and the traction time does not exceed 20 min, which accords with the biomechanical principle of cervical spine.
