Scapular winging is almost always caused by damage to one of three nerves that control muscles in your arms, back, and neck: the long thoracic nerve, which controls the serratus anterior muscle. the dorsal scapular nerve, which controls the rhomboid muscles. the spinal accessory nerve, which controls the trapezius …
What is the most common cause of scapular winging?
The commonest cause of scapular winging is serratus anterior paralysis, a dysfunction attributed to traumatic [2, 4, 8, 9, 11], non-traumatic [6, 8, 11, 28, 41, 51–53], and idiopathic [6, 8, 11, 28–30] lesions of the long thoracic nerve.
What causes medial winging of scapula?
Medial winging is the result of serratus anterior paralysis from injury to the long thoracic nerve. The most common etiology is neuropraxia after blunt or stretch injury.
Can scapula go out of place?
The scapula, or shoulder blades, are flat bones that connect the upper arm to the collar bone. When they come out of place, it can cause scapular winging. Scapular winging is a rare condition that can be painful.
Where are the trap muscles?
The trapezius is a muscle that starts at the base of your neck, goes across your shoulders and extends to the middle of your back. The trapezius (traps muscle) helps you move your head, neck, arms, shoulders and torso. It also stabilizes your spine and helps with posture.
How does winged scapula happen?
Most lesions associated with winged scapula are the result of blunt trauma due to repetitive movements, as seen in athletics. The most common cause of scapular winging is paralysis of the serratus anterior muscle due to the injury of the long thoracic nerve.
What is medial winging of scapula?
The most common etiology of a winged scapula is usually due to damage or impaired innervation to the serratus anterior muscle. The nerve that innervates this muscle is the long thoracic nerve. This dysfunction results in the medial border of the scapula giving a winged-like appearance.
What is winging shoulder blade?
Scapular winging involves one or both shoulder blades sticking out from the back rather than lying flat. It can happen as a result of injury or nerve damage. The scapula, or shoulder blades, are flat bones that connect the upper arm to the collar bone. When they come out of place, it can cause scapular winging.
What is pseudo winging?
Winging of the scapula occurs when the medial border of the scapula is more prominent than normal. Classically, this is caused by injury or dysfunction of the long thoracic nerve with subsequent paralysis of the serratus anterior muscle. Winging of the scapula due to other causes is known as pseudo-winging.
