shoulder complex

shoulder complex

The joints of the shoulder (acromioclavicular, sternoclavicular, glenohumeral and scapulothoracic joints) considered as a single functional unit, which rely on associated muscles (e.g., those attached to the scapula) to provide dynamic stability.

It articulates with the clavicle and humerus forming the shoulder complex. The three bony projections give attachment to a number of muscles and ligaments (Romanes, 1995; Soames, 1995).
Current literature regarding the reliability of EMG to the upper limb, specific to the shoulder complex is very limited.
Pain arising from structures around the shoulder complex are often felt in a wider area, for example the neck, upper arm or upper trunk [10] and thus may be undetected with such a 'self-perceived' definition.
A disruption of any one of these structures tends to be a minor injury without compromising of the shoulder complex. Conversely, when the complex is disrupted at two different sites, it becomes anatomically unstable leading to longer healing periods and functional consequences.
Providing the patient under arm assistance to stand or walk, pulling on the affected arm, or any attempt to move the arm actively or passively without correcting the abnormal shoulder complex alignment during movement may actually initiate or exacerbate HSP symptoms.
This is because the mechanism of a tackle can lead to the abducted arm of the tackling player being forcibly extended behind the player exerting leverage on the glenohumeral joint resulting in an injury to the shoulder complex.18
The challenge when assessing and treating shoulder pain is working out which structure(s) within the shoulder complex is responsible for the pain.
