A shoulder separation is an injury to the acromioclavicular joint on the top of the shoulder. The shoulder joint is formed at the junction of three bones: the collarbone (clavicle), the shoulder blade (scapula), and the arm bone (humerus). A shoulder separation occurs where the clavicle and the scapula come together.
Of the four rotator cuff muscles, it’s the infraspinatus muscle that often sustains damage. Swimmers and tennis players are susceptible, as are weight trainees.
Stryker received FDA clearance of its biodegradable InSpace balloon implant which replaces the need for complicated rotator cuff surgeries by restoring subacromial space in the shoulder, according to a company press release.
