Correlative study of subacromial space and acromial shoulder impingement syndrome / 中国基层医药

ABSTRACT

Objective To investigate the correlation between subacromial space and acromial shoulder impingement syndrome (SIS).Methods The clinical and imaging data of 40 patients with SIS were collected and retrospectively reviewed.The shape of acromion and tears of rotator cuff of all patients were classified.A cromion-Humerus (A-H) distance was measured.Results Among 40 patients,there were 9 cases of type Ⅰ,12 cases of type Ⅱ,19 cases of type Ⅲ.32 patients had subacromial space narrowing.7 cases had calcification in the supraspinatus tendon and 10 patients had acromioclavicular joint ostcoarthritis.There were 17 cases of type Ⅰ,15 cases of type Ⅱ,18 cases of type Ⅲ of tears of rotator cuff.6 patients had subacromial bursa thickening,5 patients had subacromial-deltoid sac fluid and 10 patients had the joint capsule fluid.2 patients had jointlabrum avulsion,3 patients had the supraspinatus muscle atrophy and 4 patients had Bankart Lesion.There was no significant difference was found in A-H distance measured with X-ray and MRI(P =0.137 0).There was positive correlation between the A-H distance and class of rotator cuff(r =0.545,P =0.000 1).Conclusion There exists some correlation between subacromial space and SIS.The diagnosis and class of SIS can be assessed according to narrowing range of subacromial space.
