The fracture is generally able to walk with the help of crutches, or other assistive devices at 70 days. However, the specific situation depends on the patient’s age, physical condition, the severity of the fracture, the location of the fracture and other factors. In general, a fracture requires about three months of rest before it grows back, and at about 70 days, the bone scab has already started to grow and is relatively strong. At this time, you can take X-ray to review the recovery of the fracture, and if the recovery is good, you can do some functional rehabilitation exercises. In the case of the lower leg or thigh, it should take about seven to eight months before you can walk independently from crutches. During the fracture period, you must pay attention to rest and not to overexert yourself to prevent secondary damage to the fracture site. Generally, you need to review the fracture healing on X-ray in about 70 days, and if the fracture heals well, you still need to walk with crutches for half a month before giving up crutches.
