Dr Ben Hope is an orthopaedic surgeon with a specialist interest in shoulder surgery.
Shoulder joints are the most mobile joints in your body, giving your arms a large range of movement.
To achieve this range of movement the shoulder is shaped like a shallow ball & socket joint. However, being shallow means that it can be unstable. The shoulder joint relies on the surrounding muscles, tendons and ligaments to keep it in a good position. Strain or damage to these tissues is common and can result in problems with shoulder movement. The shoulder may no longer operate smoothly- causing pain, stiffness and locking.
