Accuracy of unguided and ultrasound guided Coracohumeral ligament infiltrations – a feasibility cadaveric case series
Abstract Background Coracohumeral ligament (CHL) thickening, contracture, and fibroplasia have been identified in glenohumeral idiopathic adhesive capsulitis (GHIAC). The CHL is the main structure responsible for the range of motion limitations. Favorable outcomes have been reported with CHL surgica...

In vivo investigation using such infiltration techniques are warranted.http://link.springer.com/article/10.1186/s12891-020-3153-4GlenohumeralAdhesive capsulitisInjectionCoracohumeral ligamentShoulderCorticosteroid |
