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.
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. Pain medications such as NSAIDs can also be considered.
Only with operative treatment: Usual onset: Any age: Diagnostic method: Typically based on signs [4] Differential diagnosis: Lipoma, extensor tenosynovitis [4] Treatment: Watchful waiting, splinting the affected joint, needle aspiration, surgery [3] Prognosis: Not serious [3] Frequency ~3 per 10,000 per year (wrist and hand) [5]
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 ]
Extensor pollicis brevis tendon. Thumb abduction and extension at metacarpophalangeal joint. Forms radial (thumb side) border of the anatomical snuff box. De Quervain's tenosynovitis: 2 Extensor carpi radialis longus tendon. Extensor carpi radialis brevis tendon. Extension of wrist Intersection syndrome: 3 Extensor pollicis longus tendon
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.
