After the operation, it doesn't hurt to wear an external fixator for a long time, because there are no pain nerves on the bone, and the nerves that feel pain are all on the skin. It looks really scary, but after getting used to it, the patient will not feel very uncomfortable. Moreover, the center of gravity of the external fixation bracket is on the bracket, and the bones are not subjected to great force. Don't touch it, even if you massage it, it won't crack the bone. At the same time, we should massage the calf muscles frequently to promote circulation and promote healing.
I wish your father a speedy recovery.
