Snapping scapula syndrome: current concepts review in conservative and surgical treatment.

The snapping scapula, also called "washboard syndrome" is a controversial condition attributed to bony and soft tissue abnormalities. The syndrome was understimated for long time and often associated only with specific osseous abnormalities. The nodal point in the overview of the syndrome is that crepitus associated with symptomatic bursitis may be physiologic and is not uncommon a clinical presentation without any form of crepitus or craquement. In the current rewiew we analyzed the current concepts in the conservative and surgical management of snapping scapula syndrome, preceded by a description of scapular anatomy, pathophysiology of scapulothoracic articulation and clinical features of snapping scapula.
