Subscapularis Tendon Tear

Left Image: Longitudinal sonogram of the subscapularis region reveals a hypoechoic defect (yellow shade/arrows) in the expected location of the subscapularis tendon. Note the humeral cortex (blue line) and subdeltoid fat stripe (red line).

Right Image: Corresponding longitudinal transducer position technique.

Left Image: Transverse sonogram of the subscapularis region again shows a  hypoechoic defect (yellow shade/arrows) with some heterogeneous debris in the expected location of the subscapularis tendon consistent with a large retracted tear. Humeral cortex (blue line).

Right Image: Corresponding transverse transducer position technique.
