What causes depression of scapula?
Depression is accomplished through the force of gravity and the actions of the latissimus dorsi, serratus anterior, pectoralis major and minor, and the trapezius muscles. Upward rotation is accomplished by the trapezius and serratus anterior muscles.
What is scapular depression?
Scapular depression refers to the caudal motion of the scapula (scapulothoracic joint). In most instances, depression of the scapula is a passive process (due to gravity) that is facilitated by movement at the acromioclavicular joint.
What is the clinical effect of the suprascapular nerve is affected and how?
A suprascapular nerve injury presents as a vague shoulder pain with associated weakness in shoulder abduction and external rotation [3]. Later, the muscles of the shoulder girdle supplied by the suprascapular nerve may atrophy [3].
What happens if the suprascapular nerve is damaged?
Suprascapular neuropathy, or suprascapular nerve entrapment, is a condition which is due to irritation and damage to the suprascapular nerve (SSN). This condition can result in pain, weakness, or both depending on the cause.
What is quadrilateral space syndrome?
Quadrilateral space (QS) syndrome (QSS) is a relatively rare condition in which the axillary nerve and the posterior humeral circumflex artery are compressed within the QS. Fibrous bands are most commonly implicated as the cause, with true space-occupying lesions being less common.
What do depressed shoulders look like?
A depressed shoulder is easy to spot. Things to look for: A downward slope of the shoulder girdle. Increased or reduced distance between the inside border of the shoulder blade and spine.
What is scapular retraction and depression?
Depression: When the scapula moves downward on the ribcage. Adduction or Retraction: When the scapula moves toward the spine. Abduction or Protraction: When the scapula moves away from the spine.
