musculoskeletal and connective tissue disorders
Tendinitis and Tenosynovitis
Key Points
Tendinitis and tenosynovitis, unlike tendinopathy (tendon degeneration), involve inflammation. Pain, tenderness, and swelling tend to be maximal along the tendon's course. Diagnose most cases by examination, including tendon-specific maneuvers, sometimes confirming the diagnosis with MRI or ultrasonography. Treat with rest, heat or cold, high-dose NSAIDs, and sometimes corticosteroid injection.
