After 20 days of distal radius fracture, it is usually necessary to wear a plaster, which can avoid the displacement of the fracture and help to reduce the swelling. The fracture of distal radius is usually caused by the fall with the palm of the hand on the ground. If the fracture is not well aligned, it needs to be repositioned by manipulation, splinting or plaster fixation, and if the effect of repositioning is not good or the joints are involved, it usually needs surgical treatment. If the distal radius fracture has not healed after more than 20 days, even if the fracture has not been significantly displaced and the alignment is good, it still needs to be splinted and fixed. This is because external splinting can fix the fracture end, avoid displacement of the fracture, resulting in deformity of the fracture healing, and help to reduce the swelling of the upper limb. The specific treatment of distal radius fracture after more than 20 days, it is recommended to consult the doctor in time, under the guidance of the doctor.
