Diagnostic value of MRI symptoms of bursa hydrops in the subscapularis recess for shoulder adhesive capsulitis / 局解手术学杂志

ABSTRACT

Objective To evaluate the diagnostic values of MRI symptoms of bursa hydrops in the subscapularis recess in patients with shoulder adhesive capsulitis. Methods The MRI image of 157 cases recieved from September 2012 to March 2014 were retrospectively ana-lyzed. The 62 cases who were diagnosed as adhesive capsulitis in the freezing phase were regarded as the adhesive capsulitis group; the 31 cases of partial tear of rotator cuff were regarded as the rotator cuff tear group;and the other 64 cases who were undiagnosed were regareded as the control group. The presence of fluid distension of the bursa in the subscapularis recess were evaluated on the T2-weightedfat-saturated images. Results Symptoms of bursa hydrops in the subscapularis recess were found in 55 patients (55/62) with shoulder adhesive capsuli-tis, 4 patients (4/31) with superior cuff tear, and 5 patients (5/64) in the control group. The mean diagnostic values wereveracity 0. 90;sensibility 0. 89;specificity 0. 91;positive predictive value 0. 86; negative predictive value 0. 92. Symptoms of bursa hydrops in the sub-scapularis recess have a good consistency with arthroscopic or pathological results (P<0. 001). Conclusion The MRI symptoms of bursa hydrops in the subscapularis recess has an important diagnostic value for the confirmation of shoulder adhesive capsulitis.
