Tendinitis and Tenosynovitis
Introduction
Tendinitisis inflammation of a tendon, often developing after degeneration (tendinopathy).Tenosynovitisis tendinitis with inflammation of the tendon sheath lining. Symptoms usually include pain with motion and tenderness with palpation. Chronic deterioration or inflammation of the tendon or tendon sheath can cause scars that restrict motion. Diagnosis is clinical, sometimes supplemented with imaging. Treatment includes rest, nonsteroidal anti-inflammatory drugs (NSAIDs), and sometimes corticosteroid injections. Tendinopathy usually results from repeated small tears or degenerative changes (sometimes with calcium deposits) that occur over years in the tendon. Tendinitis and tenosynovitis most commonly affect tendons associated with the shoulder (rotator cuff), the tendon of the long head of the biceps muscle (bicipital tendon), flexor carpi radialis or ulnaris, flexor digitorum, popliteus tendon, Achilles tendon ( see Achilles Tendinitis ), and the abductor pollicis longus and extensor pollicis brevis, which share a common fibrous sheath (the resulting disorder is
