Triangular fibrocartilage complex injury needs to choose the treatment according to the severity of the disease. If the injury is mild, it can be treated by physical therapy and medication; if it is severe or crushed, it can be treated by surgery. 1. Mild injury: plaster or brace can be used to fixate and brake the wrist joint completely to avoid aggravating the injury. Physical therapy such as ultrashort wave can also be taken to promote the gradual repair of the damage to the triangular fibrocartilage complex. If pain symptoms are obvious, oral non-steroidal anti-inflammatory drugs, such as ibuprofen, celecoxib, meloxicam, etc., can be taken to relieve pain. 2. Severe injury: arthroscopic surgical treatment is usually chosen. Through the wrist arthroscopy for examination, suture the damaged triangular fibrocartilage complex, and gradually restore the function of the wrist joint. 3. Crushing injury: If the patient’s triangular fibrocartilage complex is seriously crushed, it is usually difficult to cure, and it is usually necessary to completely remove the damaged complex through surgery to restore the activities of the wrist joint. All of the above medications should be used under the guidance of a doctor to avoid self-medication.
