DRUJ
Pronunciation: druj (rhymes with 'budge')
Also written as: DRUJ — distal radioulnar joint
Distal radioulnar joint that allows forearm rotation between the radius and ulna bones.
Full Definition
The distal radioulnar joint (DRUJ) is a pivot synovial joint located at the wrist between the distal radius and ulnar head. This joint is stabilized primarily by the triangular fibrocartilage complex (TFCC) and allows for pronation and supination of the forearm. DRUJ instability can result from acute trauma, such as wrist fractures or dislocations, or from degenerative changes. Clinical assessment includes evaluating for pain, clicking, and instability during forearm rotation. DRUJ pathology significantly impacts hand and wrist function, particularly activities requiring forearm rotation such as turning doorknobs or using screwdrivers.
Usage
Usage note: Typically pronounced as a word rather than spelled out letter by letter.
