How Chiropractic Can Help Shoulder Instability Sufferers

shoulder painShoulder instability occurs when the shoulder joint is too loose and the ‘ball’ of the humerus (upper arm) can move around too much in the ‘socket’ of the scapula. In a healthy shoulder joint, the four tendons that make up the rotator cuff hold the scapula and humerus in place, together with three sets of ligaments. These usually prevent too much movement at the shoulder; however, damage to these structures can lead to looseness and instability.

Medically speaking, a distinction is made between cases of shoulder instability in which a loose joint leads to the bones moving slightly out of place (termed shoulder subluxation) and a more severe instability where the joint is completely displaced (dislocation). Patients with shoulder instability often complain that their shoulder feels as though it is about to move out of place.
Instability of the shoulder tends to occur most often in three types of patients: those who have previously dislocated their shoulder, active individuals who play sports with an ‘overhead’ action, and those who are “double-jointed”.

Shoulder dislocation occurs when the ligaments are stretched or torn, and this may lead to eventual shoulder instability if the ligaments do not heal correctly. In patients under 35 years old who experience shoulder dislocation, roughly four out of five can be expected to suffer from chronic instability afterwards, unless treatment is done to facilitate proper healing.

Athletes who repeatedly make overhead movements as part of their sport may stretch the shoulder ligaments to the point of instability. Those at risk include tennis players, swimmers and baseball pitchers. Even if dislocation does not occur, the very real fear of the joint moving out of place during a sporting event will often impair both performance and enjoyment.

“Double-jointedness”, or the ability to move joints further than normally possible, is characterized by ligaments that are intrinsically more ‘stretchy’ due to the increase of specific yellow fibers. People with this condition are therefore naturally more prone to suffer from joint instability in general than other members of the population.

Non-surgical treatments for shoulder instability include pain medication (often with the use of NSAIDs like ibuprofen to reduce inflammation, with cortisone injections being advised in severe cases), hot and cold compresses, chiropractic adjustments, and avoidance of certain movements that are known to exacerbate the condition. Once the pain and inflammation have been brought under control, exercises to strengthen the soft tissues of the shoulder may be helpful.

Most patients are able to regain function in their shoulder after six to eight weeks of treatment, depending on the severity of the injury. However, if non-surgical treatment remains ineffective after three to six months, surgery may have to be considered.

Younger (under 35 years old) patients usually tear their shoulder labrum (a so-called ‘Bankart tear’), which can be repaired by reconnecting the affected ligaments to their original position. Older patients, however, are more likely to experience a rotator cuff injury. Rotator cuff surgery that repairs the damaged ligaments is an option for the injuries that do not respond well to non-invasive treatment.

In all cases, ongoing consultation with your chiropractor is recommended to determine which treatment option is best for you.
