目的探讨冈上肌出口位摄片在肩关节损伤中的诊断价值。方法回顾性分析142例经MRI及临床诊断证实为肩峰撞击综合征和肩袖损伤的患者冈上肌出口位X线片的影像学表现。根据Bigliani肩峰分型标准进行分型,同时测量肩峰与肱骨头间距离。结果 142例患者中,Ⅰ型36例(25.35%),Ⅱ型46例(32.39%),Ⅲ型60例(42.26%)。肩峰下间隙狭窄(A-H间距<10mm)37例,肩峰骨赘形成88例,冈上肌肌腱钙化9例。结论冈上肌出口位摄片能够提供肩峰分型的直接依据,可观察肩峰下滑动间隙、肩峰端骨赘以及冈上肌肌腱钙化,对肩峰撞击综合征和肩袖损伤的病因诊断以及临床医师制定手术方案提供重要依据。
Objective To investigate the diagnostic value of supraspinatus radiograph at the shoulder joint injury. Methods A retrospective analysis was performed on the radiographic features of the X-ray at the exit of the supraspinous muscle of 142 patients with confirmed acromion impingement syndrome and rotator cuff injury by MRI and clinical diagnosis. According to the Bigliani acromion classification criteria, while measuring the distance between the shoulder and the humeral head. Results Among the 142 patients, 36 cases were type Ⅰ (25.35%), 46 cases were type Ⅱ (32.39%) and 60 cases were type Ⅲ (42.26%). There were 37 cases with subacromial space narrowing (A-H spacing <10mm), 88 cases with acromioclavicular osteophyte, and 9 cases with supraspinatus tendon calcification. CONCLUSIONS: The supraspinatus exit radiographs provide a direct basis for the classification of acromion. Observations may be made of the sub-achalasial gliding gap, the acromioclavicular osteophyte, and the calcification of the supraspinatus tendon. The effects on the causes of acromion syndrome and rotator cuff injury Diagnosis and clinicians to develop surgical programs provide an important basis.
