Three months after the distal ulnar radius fracture, the limitation of wrist extension and turning needs to be clarified firstly, and the more common causes are deformity healing, adhesion of periarticular tissues, etc. The treatment also needs to be given according to the specific causes of the disease, such as general treatment, physiotherapy, medication, and surgical treatment. 1. Deformity healing: mostly seen in distal ulnar radius fracture for external fixation conservative treatment, due to the manipulation of reset did not completely restore the anatomical position, affecting the activities of the wrist joint. For less serious deformity healing, external fixation brace can be given for orthopedic treatment, while for more serious deformity, surgical treatment, such as osteotomy, etc. is needed. 2. Adhesion of periarticular tissues: It is mainly caused by the long time fixation of wrist joint after fracture, and it is necessary to strengthen the functional exercise of wrist joint, especially the passive and active activities of wrist joint in all directions, until the flexion and extension of wrist joint is restored, and the pain during the period can be treated with non-steroidal anti-inflammatory drugs such as ibuprofen, and the adhesion is serious and can also be given to the treatment such as loosening surgery. It is recommended to go to the hospital for consultation and treatment after clarification of the condition, and the medication should be used under the guidance of a professional physician.
