The protracted scapular position creates many of the dysfunctional problems associated with chronic AC separations, including impingement and decreased demonstrated rotator cuff strength. However, scapular and shoulder dysfunction can also occur in type II injuries if the AC ligaments are torn.
30 Οκτ 2023 · Acting in conjunction with the pectoral girdle, the shoulder joint allows for a wide range of motion at the upper limb; flexion, extension, abduction, adduction, external/lateral rotation, internal/medial rotation and circumduction.
Protraction and retraction are anterior-posterior movements of the scapula or mandible. Protraction of the scapula occurs when the shoulder is moved forward, as when pushing against something or throwing a ball. Retraction is the opposite motion, with the scapula being pulled posteriorly and medially, toward the vertebral column.
Depression and protraction = anterior depression. Depression and retraction = posterior depression. The movement of the scapula along the thoracic cage also directly influences the biomechanics of the shoulder complex as a whole, and can moreover predispose the development of impingement syndrome.
14 Δεκ 2018 · Shoulder impingement is associated with greater scapular protraction (in the resting positions), greater posterior tilt (during abduction) and greater internal rotation (during plane elevation). Furthermore, the scapula shows less upward rotation when the scapular plane is elevated [ 9 ].
The most common symptoms of scapular dyskinesis include: Pain and/or tenderness around the scapula, especially on the top and medial (inner) border.
It is essential to understand the anatomical features of the shoulder when assessing and treating these conditions. This article discusses the key anatomical structures of the shoulder complex, including the bony structures, articulations, ligaments, muscles, nerves and the vascular supply.
