摘要
目的 :为肩胛盂骨折切开复位内固定提供一种较好的手术入路 ,并为临床应用提供解剖学基础。方法 :利用 2 0具经动脉灌注红色乳胶的成人上肢标本 ,对肩关节后方的有关解剖结构 ,即三角肌后部、冈下肌、小圆肌、大圆肌的形态、比邻及其间的神经界面等进行了观测 ,临床应用 4例。结果 :三角肌和冈下肌与小圆肌之间存在神经界面。沿小圆肌上缘与冈下肌之间进入 ,可避免损伤腋神经和旋肱后、旋肩胛血管。结论 :后方入路对肩胛盂横行、纵行和粉碎骨折都适合 ,是肩胛盂骨折的最好手术途径。
Objective: To provide a better operative approach for internal fixation to the fractures of the glenoid cavity and to provide anatomical basis for avoiding damage of important nerves and blood vessels.Methods:The shape,relation and inter nerve plane of the posterior part of the deltoid,infraspinatus,teres minor and teres major on 20 upper limbs of adult cadavers whose arteries were infused with red ink emulsion and were observed in operative layer.Then this approach was clinically applied in 4 cases.Results:There is a inter nerve plane among deltoid,infraspinatus and teres minor.When adopted posterior approach,the incision along the cleft between the infraspinatus and teres minor may avoid to damage of axillary nerve and blood vessels.Conclusion:The posterior operative approach can be applied in transvers,vertical and comminuted fractures.It is the best operative approach to the fractures of the glenoid cavity.
