Fractures of the lower end of the radius mainly present as swelling and significant pressure pain in the wrist. This disease is mostly caused by indirect violence, when falling, the hand lands and the violence is transmitted upward, thus the fracture of the lower end of the radius occurs. Prevention of wrist swelling and pressure pain: This disease is caused by traumatic factors, so pay attention to the safety of production life, avoid trauma and ensure personal safety is the key to prevent this disease. 1. Non-displaced fracture Fix the wrist joint in functional position for 3-4 weeks with a plaster quadruple head band or small splint. 2. Displaced extension fractures or flexion fractures can be successfully repositioned manually. For extension fractures, non-comminuted fractures that do not involve the joint surface are often repositioned by shaking; for elderly patients, comminuted fractures that involve the joint surface are often repositioned by lifting and pressing. After repositioning, the wrist joint is kept in palmar flexion and ulnar deviation and fixed in a cast or external fixation frame for 4 weeks. In flexion fractures, the direction of repositioning is reversed after longitudinal traction, and after repositioning, the wrist joint is fixed in dorsiflexion and rotation forward position for 4 weeks. After fixation, X-ray films are taken to check the alignment. After the swelling subsides in about 1 week, the films should be taken for review and promptly treated if re-displacement occurs. Older people are older, their ability to respond to changes in the surrounding environment is reduced, and their ability to maintain body balance is reduced. When they encounter a more complex environment, especially in winter due to environmental changes caused by cold, accidents may occur. The bones of the elderly are relatively lax and fragile, and fractures can occur with very little external force.
