Triangular fibrocartilage complex injury can be treated by the following methods: First, if the injury is mild, it can be treated by wrist braking, ultrashort wave therapy, and non-steroidal anti-inflammatory drugs, such as celecoxib, which can promote the gradual repair of the injury of the triangular fibrocartilage complex. Secondly, if the damage of deltoid fibrocartilage complex is severe, we need to consider surgical treatment, through the wrist arthroscopy, and suture the deltoid fibrocartilage complex, so that the damage will be gradually healed, and can completely restore the function of the wrist joint, as well as the normal movement. The majority of patients will be cured by these methods. In special cases, such as severe comminution of the triangular fibrocartilage complex, it is usually difficult to cure, and the only way to restore wrist movement is to completely remove the complex through surgery.
