The right distal radius fracture is almost four months old and still hurts. It is considered that cartilage and ligament injuries, non-union and delayed healing of the fracture delayed healing, malunion and pseudoarthrosis at the fracture site can lead to pain. It is necessary to observe the healing status of the fracture. If a pseudo joint is formed at the fracture, 2 surgeries with bone grafting are required. 1. Cartilage and ligament injury: the fracture is more serious at the time of injury, which involves articular cartilage and ligament injury, the soft tissue injury is more serious after the injury, the local scar is formed, and the fracture is not completely healed and recovered after four months, which leads to the pain of the right radius fracture even after four months. 2. Fracture non-healing and delayed healing: If the fracture is not healed or delayed healing due to the seriousness of the fracture or non-standardized fixation during the treatment, the fracture will not be recovered and the fracture of the distal end of the right radius will still hurt after four months. If the fracture does not heal or healing is delayed, it is necessary to observe the fracture for about one or two months before deciding whether to operate or not. 3. Deformed healing and pseudo joint formation at the fracture site: If the alignment and alignment are not good after the fracture, deformed healing and pseudo joint formation at the fracture site can occur. Deformed healing and pseudo joints can occur. In this case, the abnormal joint movement will pull the muscles and soft tissues in other parts of the body, resulting in the fracture of the distal end of the right radius still hurts after four months. When suffering from right distal radius fracture for four months, and still have the symptom of pain, need to pay attention to, may be not timely functional exercise caused. Patients need to actively cooperate with the doctor to take functional exercise, such as the deep grip of the fingers, wrist flexion and extension exercise.
