Trigger finger, or stenosing flexor tenosynovitis, is one of the most common causes of hand pain in adults, and its pathogenesis is often idiopathic.
Signs and symptoms include joint pain, difficulty moving a joint, a slightly flexed finger at rest, edema, and muscle tenderness. Infectious etiologies will include erythema and fever.
Treatment depends on etiology and includes antibiotics, steroid injection, and possibly surgery.
