scapular winging, exterior house painting injury

"Scapular winging represents a rare phenomenon that most commonly results from nerve damage to either the long thoracic nerve, spinal accessory nerve, or, less commonly, the dorsal scapular nerve.

This injury results in an abnormal scapulohumeral interaction during kinetic motion known as scapular dyskinesis. In this case report, the patient presented with scapular dyskinesis and medial scapular winging caused by overhead weight-lifting exercises, and a long thoracic nerve injury was diagnosed.

 Physicians are encouraged to consider long thoracic nerve damage in a patient with a history of repetitive overhead movements who presents with scapular dyskinesis and the corresponding restriction of overhead arm motions."

"Scapular winging can markedly hinder the function of the upper extremity. Nerve damage represents the most common cause, most often to the long thoracic nerve or the spinal accessory nerve.1 Additional causes of scapular winging include direct trauma to the scapulothoracic muscles or structural abnormalities that result in shoulder instability.

Medial winging of the scapula manifests with damage to the long thoracic nerve, and lateral winging occurs with damage to the spinal accessory nerve or the dorsal scapular nerve, although the latter is less common.

 Serratus anterior paralysis is not a common comorbidity, with 1 case of long thoracic nerve damage among 38,500 patients with this condition.

Seventeen different muscles attach to the scapula. The serratus anterior and lower trapezius muscles are the major contributors to the stabilization of the scapula
