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.
[3]: 102 Extra-articular tumors are usually found in the knee, thigh, and foot. [ 3 ] : 101 Symptoms include swelling, pain, sensitivity, and/or limited range of motion. [ 3 ] : 102 The rate of reoccurrence is estimated to be 18-46% for intra-articular tumors and 33-50% for extra-articular tumors.
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.
Trigger finger, also known as stenosing tenosynovitis, is a disorder characterized by catching or locking of the involved finger in full or near full flexion, typically with force. [2] There may be tenderness in the palm of the hand near the last skin crease (distal palmar crease ). [ 3 ]
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 ...
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 ...
Treatment for de Quervain tenosynovitis focuses on reducing inflammation, restoring movement in the thumb, and maintaining the range of motion of the wrist, thumb, and fingers. [6] Symptomatic alleviation (palliative treatment) is provided mainly by splinting the thumb and wrist.
The tarsal tunnel is delineated by bone on the inside and the flexor retinaculum on the outside. People with TTS typically complain of numbness in the foot radiating to the big toe and the first three toes, pain, burning, electrical sensations, and tingling over the base of the foot and the heel.
