What is closed treatment for tenosynovitis?

Corticosteroid injection therapy for tenosynovitis is a non-surgical treatment approach targeting tenosynovitis. Its core principle involves localized drug injection to relieve pain and inflammation. This method typically involves the following steps: 1. Diagnosis and localization: The physician performs a physical examination to confirm the diagnosis of tenosynovitis and determine the precise location for drug injection. 2. Preparation of medications: The injected medications usually include local anesthetics (such as lidocaine, procaine), corticosteroids (such as hydrocortisone), and possibly other anti-inflammatory or neurotrophic drugs. 3. Injection procedure: After disinfecting the injection site, the physician inserts a needle through the outer layer of the tendon sheath and administers the medication into the tendon sheath. 4. Efficacy and precautions: Corticosteroid injections can provide temporary relief from pain and inflammation caused by tenosynovitis, but they do not offer a permanent cure. After treatment, patients should avoid strenuous activities and contact with water to promote recovery.
