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.

Somatic Spinal Reflexes
One of the most well-known somatic spinal reflexes is the stretch reflex, which is activated by the sudden stretching of a muscle. This reflex involves the activation of specialized sensory receptors called muscle spindles, which are located in the muscle tissue and detect changes in the length and speed of muscle contractions. When a muscle is suddenly...
