Winged scapula

Winged Scapula

Winged scapula (pronunciation: /ˈwɪŋd ˈskæpjʊlə/) is a condition in which the scapula (shoulder blade) protrudes from a person's back in an abnormal position.

Etymology

The term "winged scapula" is derived from the Latin words "scapula," meaning shoulder blade, and "ala," meaning wing. The condition is so named because the protruding scapula resembles a wing.

Definition

A winged scapula is a skeletal medical condition where the scapula protrudes out on the back, rather than lying flat against the back of the chest wall. It usually results from damage to the long thoracic nerve that innervates the serratus anterior muscle, which is responsible for holding the scapula against the chest wall.

Symptoms

Symptoms of a winged scapula can include pain, weakness in the shoulder and arm, and limited range of motion. In severe cases, it can affect a person's ability to lift, pull, and push heavy objects.

Causes

The most common cause of a winged scapula is injury to the long thoracic nerve. This can occur as a result of trauma, surgery, or heavy physical activity. Other causes can include muscular dystrophy, nerve damage due to viral illnesses, or damage from certain cancer treatments.

Treatment

Treatment for a winged scapula typically involves physical therapy to strengthen the serratus anterior muscle. In some cases, surgery may be necessary to repair the long thoracic nerve or to reposition the scapula.
