肱骨头的相对高度与肩峰下撞击综合征的相关性研究

目的　通过测量肱骨头的相对高度，探讨肩峰下撞击综合征的肱骨侧致病因素。  方法　应用MSCT及计算机软件测量26例肩峰下撞击综合征患者(实验组)的肱骨头相对高度，与随机选取的26例健康成人（对照组）肱骨头相对高度进行对比，比较肩峰下撞击综合征患者与正常人群的肱骨头相对高度数值是否具有统计学差异。  结果　实验组肱骨头相对高度为(0.88±0.18)cm，对照组肱骨头相对高度为(1.07±0.20)cm，经配对资料的t检验示P<0.01，肩峰下撞击综合征组与健康成人组肱骨头相对高度数据的差异具有统计学意义。  结论　肩峰下撞击综合征患者肱骨头相对高度明显小于健康成人，肱骨头相对高度可以作为肩峰下撞击综合征的诊断和治疗依据。

The study on the correlation between the relative height of the humeral head and the subacromial impingement syndrome

Objective　To provide new theoretical basis for clinical diagnosis and treatment of subacromial impingement syndrome.　Methods　Using MSCT and PC software we measured the relative height of the humeral heads in 26 cases who sustained subacromial impingement syndrome and 26 cases of healthy adults who were randomly selected. Comparison of the relative height of the humeral heads in two groups was then carried out.　Results　The measurement results of the relative height of the humeral heads was (0.88±0.18) cm in the experimental group and was (1.07±0.20)cm in the control group. Compared with the control group, the relative height of the humeral heads in the experimental group was smaller (P<0.01) Conclusion　The risk of development of subacromial impingement increases with a larger relative height of the humeral heads and vice versa.
