High resolution ultrasound (HR-US) dynamic assessment of the coraco-humeral ligament (CHL) in young and elderly people

Purpose: The aim of our paper is to describe the ultrasonographic appearance of such ligament along its whole course and not just at the reflection pulley. Method and materials: We performed a HR-US scan of 45 shoulders in patients that reported no previous injuries. We divided the patients into group A (15 patients, 19 to 35 years), group B (15 patients, 36 to 55 years) and group C (15 patients, 56 to 81 years). We performed longitudinal scans to depict the short axis of the CHL, starting from its arising on the coracoid. We then performed axial scans to clearly depict the long axis of the CHL with intra- and e…
