Whether or not radial tuberosity tenosynovitis is serious should be carried out according to the patient’s symptom judgment, the methods include local pressure, clenched fist ulnar deviation test. Radial tuberosity tenosynovitis refers to aseptic inflammation of the tendon sheath of the radial tuberosity due to the repeated friction of the tendons of the extensor hallucis longus and extensor digitorum longus in the tendon sheath of the radial tuberosity caused by long-term wrist activities. There is localized redness, swelling, pain, and limitation of wrist joint movement in severe cases. If the radial tuberosity can be pressed locally without obvious pain, swelling, or nodules, and the fist ulnar deviation test is performed (holding the fist, with the wrist deviated to the ulnar side), the pain and discomfort are small, and the symptoms are usually not serious. If the localized pain is obvious when pressing the radial tuberosity, accompanied by swelling and hard nodules, and the pain is obvious in the fist ulnar deviation test, then the radial tuberosity stenosing tenosynovitis is serious. Radial stenosis tenosynovitis is recommended to actively consult the doctor and standardize the treatment under the guidance of the physician.
