Figure 4

Ultrasound images of the subacromial area in healthy and painful shoulders. Healthy nonpainful shoulders (arrows): Sub tendon (a), SA bursa (b), and SupraS tendon (c). Painful subacromial disorders (arrowheads): Sub tendinopathy (d): inhomogeneous echogenicity and local hyperechoic finding within the tendon; SA bursitis (e): increased thickness of the bursa; SupraS calcific tendinitis (f): an obvious hyperechoic line within the tendon signifying calcification; partial thickness of SupraS tendon tears (g): dimpling of the deltoid muscle into the SupraS tear site; full-thickness tear of SupraS tendon (h): discontinuity of SupraS tendon fibers, and increased hypoechoic signals at the tear site.
