Steel nailing after a fracture usually has no sequelae, specifically because the nail is used to fix the fracture end, keep it stable and facilitate smooth healing. The nail usually remains in the body for about one year, i.e., it is removed by reoperation, so it is difficult to produce sequelae in the body, and even if there are a few electrolytic reactions, they do not have a significant effect on the body. In addition, patients with localized nail holes in the process of steel nail removal will gradually recover through increased nutrition and rehabilitation exercises, and will fully recover in 3-6 months without fracture and other sequelae as long as attention is paid to avoid strenuous exercise. Patients with fractures do not need to worry excessively about steel nails, regularly removed, will not leave sequelae.
