Flexor tenosynovitis is a painful condition of finger and knuckle joint. In this condition the flexor tendons of hand become stiff, swollen and painful. Tenosynovitis is inflammation of synovium, a sheath filled with fluid that surrounds a tendon. When flexor tendons are affected, the condition is called flexor tenosynovitis. There is swelling at the base of affected finger. Patient complains of pain when he moves his finger. He feels pain while clasping his fist or while releasing the clenched fist.
The affected finger tends to get locked up (fixed) in one position.To bring back the locked up finger back to normal is painful task. This disorder can occur as a result of overuse of finger joint, rheumatoid arthritis or due to infection. Tenosynovitis in majority of cases is treated conservatively with anti inflammatory medicine and antibiotics. Surgery may be required in some cases to release the tension around the flexor tendons.
Flexor tendons of hand which originate from elbow joint pass through wrist to get attached on the distal portion of fingers. The main function of tendons is to attach bones, muscles and cartilage.Each tendon in palm and fingers is covered with a sheath called synovial sheath containing fluid. It provides lubrication and flexibility to the joints of finger and palm. In flexor tenosynovitis there is inflammation of this sheath as a result fluid builds up and it becomes difficult to flex the fingers. The condition usually exists in any finger but most often thumb and index finger is commonly affected.
The most common reason for flexor tenosynovitis is bacterial and viral infection. Infection caused due to deep punctured wounds or bites of an animal are prominent reasons. It can also occur as a result of overuse of fingers as in typists. People suffering from rheumatoid arthritis and diabetes may also suffer from flexor tenosynovitis.
