Walking without weight bearing after fracture means that the fractured limb does not touch the ground, but uses crutches, walker or healthy limb to receive force and walk. Generally speaking, for fractures of the lower limb, early weight-bearing walking is not recommended because activities will affect fracture healing. The activities on the ground usually require crutches, walking aids, and the affected limb does not step on the ground, in addition to relying on the healthy limb for compensatory activities. This state is due to the fact that the affected limb is in a state of flexion and suspension, i.e., non-weight-bearing activities. When the fracture tibia about 2 months time can be part of the assisted activities, such as the affected limb can be stepped on the ground, and according to the healing situation to apply appropriate strength. When the fracture is completely healed, weight-bearing walking of the affected limb can be performed. Early weight-bearing walking is not recommended after fracture, early weight-bearing walking will affect the healing of the fracture, so it is recommended to carry out activities with assistive devices, crutches and so on.
