Following set of representative shoulder ultrasound images have been submitted by Dr Subhash Tailor, MD-Consultant Radiologist at Bhilwara.
CASE 1 - PARTIAL SUPRASPINATUS TENDON ARTICULAR FIBRES TEAR
A 45 yrs male with h/o trauma right shoulder , painful arc syndrome & inability to abduct right shoulder .
AT US – focal inhomogenicity with hyopoechoic defect in articular fibres of right supraspinatus tendon , & adjacent GT cortical iiregularity , s/o partial supraspinatus tear. [ see figure 1 ]
Figure 1- Focal inhomogenicity supraspinatus with adjacent greater tuberosity cortical irregularity s/o -Partial tear articular fibres
CASE 2 - FOCAL FULL THICKNESS TEAR SUPRASPINATUS TENDON
A 60 years female with h/o trauma with pain & inability to abduct shoulder
AT US - focal fluid filled defect in supraspinatus tendon involving full thickness with mild subdeltoid bursal effusion . [ see figure 2]
Figure 2 – shows echolucent full thickness defect in supraspinatus tendon with mild subdeltoid bursal effusion
CASE 3 - FULL THICKNESS SUPRASPINATUS TENDON TEAR WITH COMPLETE RETRACTION , BARE TUBEROSITY SIGN
A 75 years old man with h/o fall , & was unable to abduct shoulder
AT US - There is complete absence or nonvisualsation of supraspinatus tendon at its position , s/o Naked/ Bare tuberosity sign . In this case deltoid muscle is directly resting on humeral head . [see Figure 3]
