Shoulder instability occurs when the structures surrounding the shoulder joint fail to keep the ball of the upper arm bone (humerus) within the shoulder socket (glenoid) and people will give their shoulder could be ‘loose’ or ‘giving way’. This condition can result from injury, repetitive motion, or congenital factors, leading to pain and dysfunction.
The shoulder is a ball-and-socket joint composed of three bones: the humerus (upper arm bone), the scapula (shoulder blade), and the clavicle (collarbone). The head of the humerus fits into the shallow socket of the scapula called the glenoid. The shoulder joint is stabilized by a combination of ligaments, tendons, and muscles, including the rotator cuff and the labrum, a ring of cartilage that deepens the socket.
Shoulder instability can occur due to the stretching, tearing, or detachment of the ligaments, capsule, or labrum. This instability can be classified into three types: anterior, posterior, and multidirectional. Anterior instability is the most common and often results from a dislocation or subluxation. Posterior instability is less common and can occur due to trauma or repetitive stress. Multidirectional instability involves looseness in multiple directions and is often associated with generalized ligamentous laxity. The condition can lead to repeated dislocations, subluxations and lots of moments of feeling their shoulder is not there to support them.
The primary symptoms of shoulder instability include pain, repeated dislocations or subluxations, and a sensation of the shoulder feeling loose or unstable. Pain is often exacerbated by certain movements, particularly those involving overhead activities. Individuals may also experience weakness and a reduced range of motion. In cases of chronic instability, there may be visible deformity or swelling, as well as the other symptoms.
Your OHL Physio will assess your shoulder clinically, and possibly review any imaging you’ve had, and they will make a decision whether you need an urgent orthopaedic review (due to the severity of damage) or offer you the great option of a rehabilitation pathway.
There is mountains of high-quality research showing physio-led expert exercise therapy can help manage this condition and reduce risks of needing a big orthopaedic procedure. Physio treatment aims to restore stability, strength, and function to the shoulder. This includes exercises to improve the range of motion, strengthen the rotator cuff and scapular muscles, and enhance proprioception and neuromuscular control. Techniques such as manual therapy, taping, and the use of modalities like heat or cold therapy may also be employed. A structured rehabilitation program from your trusty OHL Physiotherapist, can provide a systematic approach to recovery, incorporating strength, proprioception, plyometric training, and kinetic control.
