Regarding how long it takes to walk after bone grafting surgery, it is mainly divided into the following three situations: 1. If the bone grafting site is in the upper limb, then as long as the doctor allows, the patient can go down to the ground immediately for weight-bearing activities because the bone grafting here doesn’t affect the patient’s ability to walk on the ground with weight-bearing. 2. If the bone grafting site is in the spinal column, such as the cervical vertebrae, lumbar vertebrae, it takes at least four weeks for the patient to be able to go down to the ground and walk on the ground with weight-bearing. 3. If the implanted bone is in the lower limbs, it will take at least 3-6 months before the patient can walk with weight on the ground. Because the lower limbs are directly involved in weight-bearing and need to do a wide range of activities, it is necessary to ensure that the bone grafts have survived and the fractures in the lower limbs have completely healed before they can be put under weight and walk on the ground. In the clinic, regarding how long it takes to be able to walk on the ground after this kind of surgery, it is important to follow the doctor’s advice, because according to different parts of the bone graft, different degrees of injury and different healing conditions, the time to walk on the ground with weight-bearing varies, and the patient must not walk on the ground with weight-bearing without authorization.
