title: Closed flexor tendon ruptures.
abstract: We review different causes, diagnoses, and treatment options of closed flexor tendon disruptions in the hand. A classification of closed tendon ruptures based on their mechanism includes traumatic tendon avulsion, spontaneous midsubstance rupture, attrition rupture, infiltrative tenosynovial rupture, and iatrogenic. Certain conditions result in tendon disruption inflicted by more than 1 of these etiologies. In rheumatoid arthritis, tendon rupture may result from attrition on an exposed rough surface, proliferative tenosynovial tendon infiltration, or steroid use.
