​Bones are cut or re-shaped during surgery in order to correct a deformity such as a bunion, or to site an implant such as an ankle replacement or cartiva implant. This weakens the bone and you can suffer a fracture close-to, or through, the site of surgery. If this happens you might need to wear a boot or plaster after surgery and your recovery will probably take longer than expected. If the fracture is severe or not likely to heal, then you might need more surgery to treat the fracture.
