[Overuse injury syndromes of the hand, forearm and elbow].

The basic role of the shoulder, upper arm, elbow, forearm, and wrist is to place the hand in the appropriate position, so that it can fulfill its function. The upper extremity, especially the wrist and the hand, has a very complex anatomy with a large number of bones, muscles, tendons and nerves. They are essential to work and sport activities and are subject to acute and/or chronic mechanical injuries. This is why overuse injuries are the most common in these regions. They are often characterised by tendinitis, tenosynovitis, tunnel syndromes, or stress fractures. This paper gives an overview of the most common overuse syndromes of the hand, wrist, forearm and elbow, describing their characteristic symptoms and methods of diagnosis and treatment. The syndromes are trigger finger, dorsal radiocarpal impingement syndrome (gymnast's wrist), DeQuervain's disease, tenosynovitis of other dorsal compartments, intersection syndrome (oarsman's wrist), flexor carpi ulnaris tendinitis, flexor carpi radialis tendonitis, humeral epicondylitis (tennis elbow), posterior impingement syndrome of the elbow, medial tension and lateral compression syndrome, stress fracture in the hand, wrist, forearm and elbow, and tunnel syndromes.
