肩胛骨Y位的摄影技巧及临床价值

目的 探讨肩胛骨Y位摄影技巧及临床价值.方法 110例肩关节外伤或者肩部疼痛患者,拍摄肩胛骨Y位.摄影方法:患者面向探测器前站立,被检侧肩关节贴近探测器,双手自然下垂,手心旋前并紧贴身体,冠状面与探测器呈55°~65°,患侧肱骨头置于探测器中心,球管向足侧倾斜15°,中心线对准肱骨头.结果 110例患者中,82例一次性拍摄成功;28例由于身体倾斜角度不合适,拍摄不成功,改变身体倾斜角度拍摄成功.显示肩峰骨折5例,弯曲型及钩型肩峰20例,肩峰 -肱骨头距离<1 cm 35例,喙突骨折2例.结论 肩胛骨Y位能够清晰显示肩袖出口骨性解剖结构,指导临床制订治疗方案,具有较高的临床价值.

Radiographic skill and clinical value of the scapula Y-position

Objective To illustrate and discuss the technique and clinical value of scapula Y-position radiography.Methods Scapula Y-position radiographies were performed on 110 patients with shoulder joint injury or omalgia.The patient standed in front of the panel face to face, with the affected joint closed to the panel, and the arms fell naturally and palms pronated to stick close to the body.The angle between the coronal plane and the panel was about 55 to 65 degree, put the affected caput humeri at the center of the panel,tilted the tube to foot-side by 15 degree,and aimed the axis at caput humeri.Results Among the 110 patients, 82 radiographies were successfully taken by the first time,28 failed because of the inappropriate body-tilt angle.We had exposed 5 acromion fractures cases, 20 flexural and hook-form acromion cases, 35 cases with the acomion-caput humeri distance less than 1 cm, and 2 coracoid fracture cases.Conclusion Scapula Y-position radiography has high clinical value that could expose the osseous anatomic exit of the rotator cuff and guide the clinical treatments.
