5. Winging of the scapula secondary to instability
This is one of the commonest causes of scapula dysrythmia (and winging).Recurrent dislocations of the shoulder leads to dysfunction of the muscles that move and support the shoulder complex and scapula. The more frequent thedislocations and the less trauma involved in causing the dislocations, the worse the scapula dysryrhmia (winging). An essential part of treating shoulder instability(recurrent dislocations) is treating the scapula dysrythmia. This is done by anexperienced physiotherapist in association with a shoulder surgeon.
6. Winging secondary to pain
This is another common cause of econdary winging and dysrhythmia of the scapula. Any painful condition of the shoulder will lead to abnormal movements of the entire shoulder complex. Reduced movement at the glenohumeral joint will lead to more compenatory movement at the scapula.
7. Brachial Plexus injury or disease
Most of the nerves supplying the stabilising muscles of the scapula arise from the Brachial Plexus. The Brachial Plexus is a bundle of nerves running from the neck to the arm. It carries the nerve supply for the muscles of the arm and shoulder. Sometimes a major accident can affect the muscles of the shoulder more than the arm and lead to winging. When there is no trauma, a condition known as Parsonage-Turner syndrome (Brachial Neuritis) can lead to weakness of the scapula muscles.

3. Muscular dystrophies,
Most commonly Facioscapulohumeral Dystrophy (FSHD), are the main cause of weakness of all the scapula stabilising muscles.
Facioscapulohumeral Dystrophy (FSHD) is one of a number of uncommon inherited disorders called muscular dystrophies. Muscular dystrophy is a progressive weakening of skeletal muscles and has varying degrees of severity. FSHD mainly affects the face muscles and the muscles around the shoulder and shoulder blade.
4. Loss of scapular suspensory mechanism
The coracoclavicular ligaments suspend the scapula from the clavicle and the acromioclavicular joint is the only joint linking the scapula to the rest of the body. Therefore dislocation of the acromioclavicular joint or a fracture of the outer third of the clavicle, with rupture of the coracoclavicular ligaments, leads to an abnormal scapula rhythm and apparent scapula winging with overhead manouevers. This is usually not painful and usually only affects overhead workers and athletes.
Another rare cause is the ‘scapulothoracic dissociation’, described by Rockwood & Matsen in 1990. The scapula is wrenched from the body in violent trauma leading to fracture of the clavicle and soft tissues around the clavicle.
The Acromioclavicular Joint is usually injured by a direct fall onto the point of the shoulder. The shoulder blade (scapula) is forced downwards and the clavicle (collarbone) appears prominent.
