Tendonitis can be cured by surgery. Early mild tendonitis can be treated conservatively by soaking the hands in hot water, applying topical fotarine, and limiting the movement of the finger joints. If the symptoms are obvious, local closure therapy or a small needle can be used to cut open the tendon sheath to release the pressure on the tendon. In a small number of patients, if the symptoms are obvious and conservative treatment is ineffective, surgical treatment can be performed. After brachial plexus anesthesia, a small 0.5-1 cm incision is made at the site of tendon sheath compression, and the tendon sheath is completely released and partially excised, after surgery, most patients will not recur.
