The Relationship of between Subacromial Impingement Syndrome and Shoulder Typing under MSCT

Objective: To study the relationship between subacromial impingement syndrome and shoulder typing under MSCT. Methods: 110 patients diagnosed with shoulder impingement syndrome in our hospital from January 2013 to January 2015 were undergone with MSCT scanning, all the patients were grouped according to different ages, gender, location shoulder to compare different shoulder peak shape in different age groups. Results: and ⅠⅡ shoulder gradually decreased in proportion with age, Ⅲtype shoulder gradually increased in proportion with age. Type Ⅱshoulder proportion of A group group was 51.6%, which was significantly higher compared with group B and group C, type Ⅲshoulder proportion of A group group was 22.6%, which was significantly lower compared with group B and group C. Ⅰ, Ⅱ, Ⅲtype acromion morphology of male group and female group didn't have the significant difference in proportion(P>0.05). Ⅲtype shoulder had the right shoulder more, the proportion was 52.5 percent, which was significantly higher than the left shoulder group(P<0.05). Conclusion: MSCT can clearly show the shape and structure of the shoulder, curved shoulder of subacromial impingement syndrome patiens gradually reduce the proportion with age increasing, hook shoulder is in the right shoulder more, and the proportion increases with age gradually increasing.
