Diagnosis and current treatment options of shoulder impingement

Abstract

A comprehensive review of shoulder impingement reveals numerous causes, contributing factors, and therapeutic options for the resolution of symptoms and return to optimal shoulder function. The clinical diagnosis of shoulder impingement is rather straightforward, but the challenge arises in identifying causative factors and directing treatment options to alleviate symptoms and restore normal function. Shoulder impingement occurs when the space between the proximal humerus and the coracoacromial arch is narrowed such that the transversing tendons, primarily the supraspinatus and to a lesser degree, the infraspinatus, are injured. As the most diagnosed shoulder ailment an understanding of shoulder anatomy, supporting musculature and function, inciting factors, and individual demands are critical in directing the appropriate treatment plan. Medications, therapeutic exercise and surgical interventions all have their place in the treatment of shoulder impingement.
