目的：观察针刀干预对颈椎病兔颈椎X线影像学的的影响。方法：6月龄新西兰兔随机分为空白组、模型组、针刀组、电针组，采用长期低头位方法制备颈椎病模型。造模后对针刀组、电针组进行治疗干预。各组动物于造模前后、干预后3个时间节点拍摄颈椎X线片。结果：颈椎X线片显示造模后颈椎曲度改变，出现反张，椎间隙变窄，部分见椎间孔变小、椎体前后缘见骨质增生；针刀干预后见颈椎曲度改善较明显，曲度由反张变为较直，部分见椎间孔较治疗前变大、椎间隙有所改善，治疗前后骨质增生未见明显变化；电针干预后见部分兔颈椎反张有改善，治疗前后椎间隙、椎间孔、骨质增生未见明显变化。造模后，模型组、针刀组、电针组颈椎X线积分均明显升高，与空白组相比差异具有统计学意义（P<0.01）；针刀干预后X线积分改善程度与模型组比较差异具有统计学意义（P<0.01）；电针干预后X线积分改善程度与模型组比较差异无统计学意义（P>0.05）；针刀组干预后X线积分改善程度较电针明显，二组比较差异具有统计学意义（P<0.05）。结论：针刀干预颈椎病可有效恢复颈椎曲度，改善颈椎X线影像学表现，纠正颈椎力学平衡。

English Summary:

This study was expected to observe the effects of acupotomy treatment on cervical X-rays in a rabbit model of cervical spondylosis(CS). Methods：Six months old New Zealand rabbits were divided into 4 groups randomly：normal control group，model group，acupotomy group，electro-acupuncture group. CS models were made by the method of flexed neck posture for long-term. After modeling，acupotomy and electro-acupuncture were applied to treat acupotomy group and electro-acupuncture group respectively. Changes of cervical X-rays taken before and after modeling，and after treatment. Results：After modeling，cervical X-rays showed that there were changes in cervical lordosis，narrowed lordotic curve with posterior convexity，a decrease in discs height，narrowed intervertebrale foramen and overgrowth of osteophytes in anterior and posterior vertebral bodies in some rabbits. There was obvious improvement in X-rays after acupotomy treatment; cervical lordosis straightened，intervertebral foramen widened in some rabbits，and there was no obvious change of osteophytes before and after treatment. After modeling，the cervical X-ray scores of the model group，acupotomy group and electro-acupuncture group increased significantly in comparison with that of normal control group (P<0.01). The reduction of X-ray scores before and after treatment in acupotomy group had a significant difference in comparison with those of model group (P<0.01).The reduction of X-ray scores before and after treatment in electro-acupuncture group had no significant difference with those of model group (P>0.05). The reduction of X-ray scores before and after treatment in acupotomy group had a significant difference compared with the electro-acupuncture group (P<0.05).Conclusion：Acupotomy in the treatment of cervical spondylosis can effectively restore cervical lordosis，improve cervical X-ray image，reestablish cervical biomechanical balance.
