摘要
目的 :为寰枢椎区病损机制和手术治疗提供解剖学依据。方法 :对 5 0例寰枢椎干燥骨标本的侧方结构进行测量 ,所得数据进行统计学处理。结果 :寰椎横突孔外倾角为 1 5 .4°± 4 .8°,横突孔后倾角为 1 7.2°± 5 .4°;枢椎横突孔外倾角为 4 8.4°± 1 1 .2°,横突孔后倾角为 32 .2°± 1 0 .5°。寰枢椎侧方骨质切除的最大宽度为 2 5 mm～ 30 mm。结论 :寰枢椎侧方结构的解剖学形态与其损伤机制及手术方法密切相关。
Objective:To provide morphological basis for the surgical therapy of injury on atlas and axis. Methods:The lateral structure of C1-2 vertebra was measured on 50 bone specimens. All acquired data were analysed by statistical methods. Results:The outside and posterior oblique angle of the transverse foramen of atlas was 15.4o± 4.8oand 17.2o± 5.4o respectively, that of axis was 48.4o±11.2oand 32.2o± 10.5orespectively. The maximal width of the bone removal was 25mm^30mm on the lateral region of C1-2 vertebra. Conclusions:Morphology of atlas and axis are correlated with its injury and operation.
