Tenosynovitis is inflammation of a tendon and it fluid-filled sheath. Symptoms typically include pain, swelling, and inability to fully straighten the joint. Tendons in the hand, wrist, and foot are most commonly affected.

Tenosynovitis may be infectious or noninfectious. Infections may occur due to injury, such as a cut or bite, or spread from elsewhere in the body. Noninfectious types include de Quervain tendinopathy, intersection syndrome, and trigger finger (stenosing tenosynovitis). Risk factors for the noninfectious types include overuse, rheumatoid arthritis, and psoriasis.

Cases due to infection of the flexor tendons require rapid treatment. Mild cases may be managed with intravenous antibiotics and splinting; while more severe cases also require surgery. Noninfectious types may be treated with NSAIDs, splinting, or corticosteroid. Up to 3% of people may have trigger finger.
