13 Μαρ 2023 · A primary winged scapula results from an injury to the nerve, changes in the scapula bone itself, or periscapular soft tissue abnormalities. Remember, the serratus anterior muscle attaches to the medial aspect of the scapula and attaches it to the rib cage.
The term ‘winged scapula’ (also scapula alata) is used when the muscles of the scapula are too weak or paralyzed, resulting in a limited ability to stabilize the scapula. As a result, the medial or lateral borders of the scapula protrudes from back, like wings.
Primary winged scapula is caused by neurologic injury, detrimental changes in the bone, or anomalies of periscapular soft-tissue . Secondary winged scapula manifests due to glenohumeral and subacromial conditions in which correction of these conditions leads to winged scapula .
Primary wing-ing occurs when muscular weakness disrupts the normal balance of the scapulothoracic complex. Secondary winging occurs when pathology of the glenohumeral joint interrupts the coordinated motion of the scapula.
This article will review the relevant anatomy, etiology, clinical evaluation, diagnostic testing, and treatment of scapular winging. It will also discuss the differences in diagnosis and management between scapular winging arising from neurogenic causes and traumatic muscular detachment.
14 Οκτ 2022 · Scapular winging, or scapula alata, is a rare scapulothoracic disorder with altered motion and positioning of the scapula (ie, scapular dyskinesis), characterized by medial border prominence of the scapula with respect to the thorax either at rest or during motion. 18, 19 This abnormal scapular motion originates from the inability of the ...
15 Ιουλ 2013 · Scapula winging is characterized by a failure of the dynamic stabilizing structures that keep the scapula anchored to the chest wall, leading to a prominence of the scapula (Fig. 1). These stabilizers are comprised of three main muscle groups: serratus anterior, trapezius and rhomboids major and minor.
