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.
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.
Infectious tenosynovitis in 2.5% to 9.4% of all hand infections. Kanavel's cardinal signs are used to diagnose infectious tenosynovitis. They are: tenderness to touch along the flexor aspect of the finger, fusiform enlargement of the affected finger, the finger being held in slight flexion at rest, and severe pain with passive extension.
It contains tendons of the flexor digitorum superficialis and the flexor digitorum profundus, but not the flexor pollicis longus. [2] The sheath which surrounds the flexor digitorum extends downward about halfway along the metacarpal bones, where it ends in blind diverticula around the tendons to the index, middle, and ring fingers. It is ...
The most important signs and symptoms of compartment syndrome are observable before actual contracture. What is known as the five Ps of compartment syndrome include: pain, generally the initial symptom, accompanied by pulselessness, pallor, paralysis, and paraesthesias. Pain will likely also increase upon extension of the affected limbs hands ...
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 ...
Linburg–Comstock variation is an occasional tendinous connection between the flexor pollicis longus and the flexor digitorum profundus of the index, the middle finger or both. It is found in around 21% of the population. [1] It is an anatomical variation in humans, which may be viewed as a pathology if it causes symptoms. It was recognised as ...
