Fracture surgery after how long can crutches depends on the specific characteristics of the fracture itself, to be because the upper limb fracture is not crutches, because in the process of crutches must rely on the upper limb to bear the force of gravity, only until the fracture is completely healed 3 months or even longer to be able to crutches. To be because of the fracture of the lower limbs after surgery, the whole cut is basically healed, about half a month or so will be able to crutches on the ground activities, but at this time the fracture of the leg is completely unable to bear weight. If there is a serious comminuted fracture, even after surgical treatment, the whole fracture fixation is not particularly strong and reliable, it is possible to delay the time of crutches to 3-4 weeks. If the fracture of the spine is fixed by surgery, basically on the second day can be able to go down to the ground on crutches, and the pain of the incision for a long time can be alleviated for 3-5 days, but the specifics also depend on the severity of the underlying spinal fracture to analyze the overall situation.
