Bone grafting surgery usually takes more than 2 months to return to normal. Bone grafting is usually used for the treatment of osteomyelitis, bone tumors and bone discontinuity. After bone grafting, local activity restriction and fixation with plaster and brace are performed to maintain the stability of the bone graft area, prevent local displacement and bone resorption, and prevent infection. Functional exercise of muscles and joints is required 72 hours after bone grafting. Through the functional exercise of contraction and diastole of local muscles, local muscle atrophy and deep vein thrombosis can be prevented; local swelling of limbs can be promoted and restored to normal state. Through active treatment, the bone graft area will heal soon.
