Jersey finger, also known as rugby finger, is a finger-related tendon injury that is common in sport and can result in permanent loss of flexion of the end of the finger if not surgically repaired. The injury is common when one player grabs another's jersey with the tips of one or more fingers while that player is pulling or running away. [1 ...
Kanavel's sign is a clinical sign found in patients with infection of a flexor tendon sheath in the hand (pyogenic flexor tenosynovitis), a serious condition which can cause rapid loss of function of the affected finger. [1] The sign consists of four components: [2] the affected finger is held in slight flexion.
The earliest sign of a contracture is a triangular "puckering" of the skin of the palm as it passes over the flexor tendon just before the flexor crease of the finger, at the metacarpophalangeal (MCP) joint. [citation needed] Late stage Dupuytren's contracture upon the left hand affecting the little finger and the ring finger but not the index ...
Infectious tenosynovitis is the infection of closed synovial sheaths in the flexor tendons of the fingers. It is usually caused by trauma, but bacteria can spread from other sites of the body. Although tenosynovitis usually affects the flexor tendon of the fingers, the disease can also affect the extensor tendons occasionally. [5]
Symptoms include catching or locking of the involved finger when it is forcefully flexed. [2] There may be tenderness in the palm of the hand near the last skin crease (distal palmar crease). Often a nodule can be felt in this area. [4] There is some evidence that idiopathic trigger finger behaves differently in people with diabetes. [5]
Four long tendons come off this muscle near the wrist and travel through the carpal tunnel formed by the flexor retinaculum. These tendons, along with those of flexor digitorum profundus, are enclosed by a common flexor sheath. The tendons attach to the anterior margins on the bases of the intermediate phalanges of the four fingers. These ...
Magnetic resonance images of the fingers in psoriatic arthritis. Shown are T1 weighted axial (a) pre-contrast and (b) post-contrast images exhibiting dactylitis due to flexor tenosynovitis at the second finger with enhancement and thickening of the tendon sheath (large arrow). Synovitis is seen in the fourth proximal interphalangeal joint ...
Climber's finger is one of the most common climbing injuries within the sport of rock climbing, accounting for about 30% of finger injuries seen in climbers. [1] It is an overuse injury that usually manifests in a swollen middle or ring finger due to a damaged flexor tendon pulley , normally the A2 or A4 pulley.
