Triangular fibrocartilage injury is considered to be caused by trauma or degenerative changes of the wrist joint when the wrist is supported on the ground during a fall or repeated weight-bearing on the ulnar side of the wrist, which can be treated by applying topical ointment locally, taking oral medication to nourish the cartilage, non-steroidal anti-inflammatory drugs, and medication to activate blood circulation and remove blood stasis, and physical therapy and surgery can also be considered. If the symptoms of deltoid fibrocartilage injury are mild, topical ointments such as diclofenac diethylamide latex can be applied locally under the guidance of a doctor to relieve muscle or soft tissue pain. At the same time, medications that nourish cartilage, such as calcium aminoglucose chondroitin sulfate tablets, should also be taken to promote cartilage repair. If there is swelling and pain at the site of deltoid fibrocartilage injury, non-steroidal anti-inflammatory drugs, blood circulation drugs, such as celecoxib capsule, blood circulation and pain relief capsule, etc., can be taken according to the doctor’s instructions, and can be supplemented with physical therapy, such as acupuncture, ultrasound, shock wave treatment, etc.. If the damage to the deltoid fibrocartilage is severe, braking and plaster immobilization should be carried out at the same time, and arthroscopic minimally invasive surgical treatment should be considered if necessary. Once the deltoid fibrocartilage injury occurs, it is recommended to go to the regular hospital as soon as possible, combined with the professional doctor’s examination and imaging examination, to determine the severity of the injury in a timely manner, and take appropriate treatment measures. The above drugs should be used under the guidance of a doctor, avoid self-medication.
