Abnormal bending of the fingers can be treated with braking and surgery if it is caused by trauma. If it is caused by arthritis, it can be treated with medication as well as surgery. Trauma to the finger may cause damage to the tendon, joint capsule, etc. It may also cause a fracture and abnormal bending. If it is a tendon rupture, it needs to be fixed by surgical repair of plaster cast; if it is a fracture, it can be fixed by manipulation of repositioning plaster or splint, or it can be treated by surgical incision and repositioning of internal fixation. If the abnormal bending is caused by osteoarthritis, rheumatoid arthritis, gouty arthritis invading the finger joints, and the pain is obvious, you can take anti-inflammatory and analgesic drugs to relieve pain, such as nimesulide, diclofenac sodium, etc., and treat the primary disease. If the curvature of the fingers seriously affects the function of the hand, it can also be treated by interphalangeal joint replacement. If the fingers are abnormally curved, it is recommended that the patient go to the hospital to determine the cause of the disease and receive regular treatment. The use of medication should be in accordance with medical advice.
