肩关节冈上肌出口位在肩关节撞击综合征诊断中的应用

Application of Supraspinatus Outlet in Diagnosis of Subacromial Impingement Syndrome

目的:探讨肩关节冈上肌出口位在诊断肩关节撞击综合征中的应用。方法:回顾性分析本院2009年-2011年确诊为肩关节撞击综合征患者40例,分析其冈上肌出口位的X线平片,依据Bigliani等人提出的肩峰分型方法分类,并测量肩峰-肱骨头值(A-H值)。结果:经分类后,获得Ⅰ型肩峰患者7例(17.5%),Ⅱ型患者15例(37.5%),Ⅲ型患者18例(45.0%)。经测量A-H值可判断:肩峰下间隙狭窄患者17例(42.5%),肩关节骨质增生患者12例(30.0%),肱骨大结节硬化患者3例(7.5%),冈上肌肌腱钙化患者8例(20.0%)。结论:在肩关节撞击综合征的临床诊断中,冈上肌出口位的X线平片可为肩峰分型及临床治疗方案的选择提供依据,肩关节冈上肌出口位在肩关节撞击综合征的临床诊断中具有重要价值。

Objective： To discuss the application of supraspinatus outlet in the treatment of subacromial impingement syndrome （ SIS ） .Method： Forty patients with diagnosis of shoulder impingement in our hospital were retrospectively analyzed in 2009-2011.Examined the patients with standard X-ray with supraspinatus outlet view and classified the acromion on the basis of the Bigliani criteria in the same manner. The acromion humerus distance （ A-H distance ） was measured at the same time.Result： After the classification, obtained in 7 patients with type I acromion （ 17.5% ）, 15 cases of type II patients （ 37.5% ）, 18 cases of type m patients （ 45.0% ） .By measuring A-H value judgment： 17 patients with narrow gap under the acromion （ 42.5% ）, 12 patients with shoulder joint bone hyperplasia （ 30.0% ）, humerus big 3 cases of patients with tuberous sclerosis （ 7.5% ）, 8 patients with calcified supraspinatus tendons （ 20.0% ） .Conclusion： The X-ray radiographs of supraspinatus outlet provide significant information for the classification of acromion and the selection of clinical therapy in diagnosis of SIS.Supraspinatus outlet plays an important role in diagnosis of SIS.
