The shoulder joint is a highly mobile joint which allows a large range of arm motion. The head of the humerus (upper arm bone) is held firmly in place in the glenoid cavity (shoulder socket) by shoulder ligaments, shoulder tendons and a rim of soft cartilage known as the labrum.
Trauma to the shoulder joint can cause a dislocation of the upper arm bone and a tear in the soft cartilage. As a result of this tear, future shoulder dislocation can occur even during normal daily activities as the joint is unstable.
Arthroscopic Surgery can be used to stabilise the shoulder joint. This operation is usually performed through keyholes using a telescope under a general and regional anaesthetic. Small incisions are made on the shoulder and a small fibre optic telescope is passed through one of these holes. Small instruments are passed through the other holes to reattach and tighten the torn cartilage and ligaments of the shoulder.
In most cases this surgery requires an overnight stay in hospital. You will be required to wear a shoulder sling for at least 4 weeks. Physiotherapy is an integral part of shoulder rehabilitation and return to normal activities will depend upon the size of your tear and the surgery performed.
