Repetitive Strain Injuries of the Upper Extremity: Imaging of Tendon Pathology and Compressive Neuropathies

Curr Probl Diagn Radiol. 2021 Jul-Aug;50(4):512-522. doi: 10.1067/j.cpradiol.2020.07.007. Epub 2020 Jul 28.


Repetitive strain injuries (RSIs) encompass a broad clinicopathologic spectrum which includes discrete patterns of tissue injury involving tendons, bursae and nerves although an element of subjective symptomatology may be contributory. Upper extremity RSIs include De Quervain's tenosynovitis, intersection syndromes, epicondylitis, ulnar, and median neuritis as well as other compressive neuropathies. It is estimated that RSIs cost the US economy over $60 billion annually and while detailed clinical examination remains the diagnostic mainstay, imaging can aid in diagnosis, guide management and reduce costs.
