A comminuted fracture of the heel bone should be put on the ground at the earliest in 2.5-3 months, because the heel bone is more cancellous bone and the cortical bone is the outer layer, similar to the structure of a duck egg shell, so early walking on the ground may lead to displacement of the fracture fragment or failure of fixation of the fracture, resulting in failure of surgical fixation. In the early stage, it is not allowed to get out of bed, but if functional exercises are required, functional exercises of the ankle joint should be performed in the early stage to prevent joint adhesions and stiffness. In addition, functional exercises of both lower limbs are required to prevent muscle atrophy and deep vein thrombosis, so don’t walk too early after heel fracture, because walking too early will have an impact on the future.
