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. It can affect a person's ability to lift, pull, and push weighty objects. In some serious cases, the ability to perform activities of daily living such as changing one's clothes and washing one's hair may be hindered.
The name of this condition comes from its appearance, a wing-like resemblance, due to the medial border of the scapula sticking straight out from the back. Scapular winging has been observed to disrupt scapulohumeral rhythm, contributing to decreased flexion and abduction of the upper extremity, as well as a loss in power and the source of considerable pain.[1] A winged scapula is considered normal posture in young children, but not older children and adults.
