- Serratus anterior palsy
- 736.89 Other acquired deformity of other parts of limb
- M21.80 Other specified acquired deformities of unspecified
- Inferior angle tilting of the scapula
- Instability of the scapula to the thoracic wall
- Scapula has the greatest number of muscles attached to it
than any other bone
- Scapula dysrhythmia
- Result of serratus anterior muscle dysfunction
- Injury to long thoracic nerve
- Often asymptomatic
- Winging can help identify a dysfunction possibly occurring
in the shoulder
- Symptoms of pain and weakness
- Can be a result of a brachial plexus injury
- Parsonage-Turner syndrome (brachial neuritis) underlying
- Loss of serratus anterior muscle
- Weakness of trapezius strength
- Weakness of scapular stabilizers
- Commonly associated with presence of other orthopedic pathologies:
subacromial impingement syndrome, rotator cuff pathology, labral
- Creates an abnormal scapulothoracic rhythm
- Commonly associated with repeated overhead or overuse activities.
- Full history of symptoms, medical history screening, and differential
shoulder orthopedic examination will ensure appropriate diagnosis.
