Rotator cuff tears are a major cause of shoulder pain and restricted mobility, with the supraspinatus tendon being particularly susceptible to injury due to its biomechanical properties and vascular perfusion characteristics. Failure to achieve an accurate diagnosis and initiate timely treatment following a rotator cuff injury can result in progressive worsening of the condition, potentially leading to severe complications. In this report, we present a case of post-traumatic supraspinatus tendon injury. By comparing musculoskeletal ultrasound, contrast-enhanced ultrasound, and ultra resolution microscopy (URM) imaging, we demonstrate that URM, as an advanced imaging modality with high resolution, real-time dynamic capabilities, and quantitative analytical potential, offers distinct advantages in detecting rotator cuff injuries. Specifically, URM improves the detection rate, delineates injury boundaries with greater accuracy, and assesses the extent of inflammatory adhesions surrounding the affected site.
