If the fracture line is still clear, it means that the fracture has not healed and has not reached the clinical standard of preliminary healing. Walking may cause the fracture to have stress reaction, which may lead to the displacement of the fracture. It is also possible that the fracture will compress the surrounding nerves and blood vessels, which will make the healing of the fracture more difficult. Moreover, if you walk a lot, the fracture will atrophy and harden, and the fracture will not be healed, and you need to perform surgery to achieve complete healing of the fracture, which will make the treatment more difficult. If this situation occurs, the correct approach should be to carry out external fixation of the fracture position of the plaster, fixation of 4-6 weeks or so to re-examine the film, to see whether to meet the clinical criteria for initial healing. If there is non-union of the fracture, the duration of cast immobilization may need to be increased. If it persists for too long and the fracture break becomes sclerotic or atrophic, surgical intervention is required.
