Shoulder instability is a common cause of consultation with an orthopedic surgeon.
Most cases are sports accidents (Rugby, winter sports …) or ordinary falls (poor reception).
The recurrences of dislocations are very frequent before the age of 25 years.
An unstable shoulder can be kept without truly dislocating itself in the form of apprehension or subluxation following the first dislocation.
The peripheral muscles play a certain role in the stability of a shoulder, weakened or not.
Hyperlaxity of the shoulders is a delicate factor for physiotherapy and medico-surgical management.
