Abstract
The shoulder is an intricate joint, capable of a wide range of movements for both daily activities and physical exercise. This intricate joint is susceptible to various injuries and conditions due to its design. Shoulder impingement syndrome (SIS), also clinically recognized as subacromial impingement syndrome (SAIS), is a prevalent source of shoulder discomfort, which is a spectrum of disorders such as rotator cuff tendinopathy, partial or complete tears, and inflammation of the subacromial bursa. SAIS can be caused by intrinsic causes, such as tendon degeneration, and extrinsic factors, such as structural abnormalities of the acromion, which contribute together to compress structures underneath the subacromial space. Initially, conservative management methods, such as organised physiotherapy and corticosteroid injections, are always advised to reduce pain, inflammation, and restore the range of motion of the shoulder. Surgical intervention, particularly acromioplasty, has been traditionally utilized whenever conservative treatment fails. In acromioplasty, a part of the acromion is shaved off to widen the subacromial space, thus releasing the pressure on the rotator cuff tendons and bursa. SAIS presentations make it harder to standardize treatments due to their diverse presentations, which emphasizes the importance of thorough, long-term research to improve diagnostic criteria and find the best ways to treat patients.
