A winged scapula (scapula alata) is a skeletal medical condition in which the shoulder blade protrudes from a person's back in an abnormal position. In rare conditions it has the potential to lead to limited functional activity in the upper extremity to which it is adjacent.
Dyskinesia can be anything from a slight tremor of the hands to an uncontrollable movement of the upper body or lower extremities. Discoordination can also occur internally especially with the respiratory muscles and it often goes unrecognized. [3] Dyskinesia is a symptom of several medical disorders that are distinguished by their underlying ...
The upper and lower fibers tend to rotate the scapula around the sternoclavicular articulation so that the acromion and inferior angles move up and the medial border moves down (upward rotation). The upper and lower fibers work in tandem with serratus anterior to upwardly rotate the scapulae, and work in opposition to the levator scapulae and ...
Symptoms are often minimal – if symptomatic, a posterior shoulder or scapular burning type of pain may be reported. Some injuries, particularly lesions, can paralyse the serratus anterior muscle to produce a winged scapula. [3] [12] This is most prominent when the arm is lifted forward or when the patient pushes the outstretched arm against a ...

Dorsal scapular nerve syndrome can be caused by nerve compression syndrome. A winged scapula is the most common symptom. [7] Shoulder pain may occur. [7] It causes weakness in rhomboid major muscle, rhomboid minor muscle, and levator scapulae muscle. [7] The range of motion of the shoulder may be limited. [7] Treatment is usually conservative. [7]
The scapula (pl.: scapulae or scapulas [1]), also known as the shoulder blade, is the bone that connects the humerus (upper arm bone) with the clavicle (collar bone). Like their connected bones, the scapulae are paired, with each scapula on either side of the body being roughly a mirror image of the other.
Injury to the nerve can result in shoulder girdle depression, atrophy, abnormal movement, a protruding scapula, and weakened abduction. [5] Weakness of the shoulder girdle can lead to traction injury of the brachial plexus. [10] Because diagnosis is difficult, electromyogram or nerve conduction studies may be needed to confirm a suspected ...
