HIGH RESOLUTION SONOGRAPHY IN ROTATOR CUFF TEAR

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]
