Shoulder instabilities
treatment
During arthroscopy, anchors are placed in the glenoid bone. These anchors have wires attached to them. These will be used to fix the bead to the bone.
What arethe possible complications?
Recurrence (3-6% if the indication has been chosen correctly), algodystrophy, retractile capsulitis and, very rarely, infection.
diagnosis
Clinical examination is invaluable in this case, especially for distinguishing between post-traumatic instability and instability due to hyperlaxity.
X-rays are the first examination to be performed afin order to rule out fractures.
Arthroscanner remains the examination of choice to confirm the diagnosis.
This will confirm the detachment of the bead from the bone and the existence of associated lesions.
symptoms
The shoulder is painful (especially when dislocated), or the pain is reduced by multiple episodes leading to instability. This pain can sometimes manifest itself as apprehension when faced with certain positions, particularly when throwing an object or arm-wrestling (tennis serve, sleeping with hands behind the head, etc.).
Definition
The shoulder joint comprises the humerus and a socket on the scapula, called the glenoid. The glenoid is surrounded by fibro-cartilage that enlarges the contact surface with the head of the humerus. This structure is called the bead.
The shoulder is the most easily dislocated joint in the body. A dislocation corresponds to the "dislocation" of the joint.
The first dislocation may occur during a violent accident (sports, motorcycle...), or following a fall.
During dislocation, the head tears away part of the pad (the anterior wall of the shoulder) and detaches the capsule usually fixed to the bone.
The frequent failure of these lesions to heal encourages recurrence. This is known as instability. If the first dislocation occurs in youth, the risk of recurrence is high. For example, when the first dislocation occurs at the age of 20, the statistical risk of recurrence is 80%. After the age of 50, recurrence is rarer, at around 10%.
Occasionally, patients present with episodes of subluxation.
The humeral head returns to its place spontaneously after a few seconds, but the shoulder remains unstable and, above all, painful.A shoulder is considered unstable when it presents several episodes of dislocation (subluxations).
