Core Tip
Core tip: Shoulder anatomical characteristics have been associated with several shoulder pathologies. We hypothesized that the shoulder gradient might be regarded as an anatomic factor affecting the occurrence of rotator cuff pathologies. Our analysis revealed no association between shoulder gradient and incidence of rotator cuff tear.
