During standard acromioplasty, the inferior fibers of the coracoacromial ligament are inevitably detached. Partial or complete sectioning of the coracoacromial ligament results in secondary weakening of the deltoid muscle and an incremental risk of anterior-superior glenohumeral migration. This technique allows the re-attachment of the inferior fibers to the intact portion of the ligament and re-establishes mechanical continuity of the coracohumeral arc.
