winging scapula

A labourer presented to GP when he noticed to have pain, limited shoulder movement, and having difficulty in performing his work which is lifting and carrying bricks at his workplace.

Name the condition above.
Winging of the right scapula.

Anatomy involved?
Long thoracic nerve.
> the longest branch of the brachial plexus.
> it is purely motor nerve supplying the serratus anterior muscle.

** Damage to or impingement of this nerve > weakening or paralysis of the muscle > cause the scapula to slip away from the rib cage, giving it the wing-like appearance on the upper back

What might be the reason for the above condition in this patient?
He is a labourer who might have used to carry excessive mechanical strains on his shoulder.

sharing is caring 3 :)

Wassalam.
