The time to remove the nail varies depending on the location of the fracture and the internal fixation device. After the surgery, the time of removal varies according to the fracture site, healing recovery, as well as the individual’s physical condition, age and other factors. Fractures of the upper limbs can usually be removed in about 12 months, and fractures of the lower limbs can usually be removed in about 18 months. If the fracture site has a rich blood supply and heals well, it can be removed after six months. For extremity fractures in weight-bearing areas, they can be removed earlier in the appropriate range to facilitate scab remodeling and contouring. Some fractures with poor healing recovery will take two years, or even longer. For younger patients in good physical condition, the nail can be removed in one year. For older patients with poor physical conditions, the removal time can be extended appropriately, and the steel nail is usually removed within 2-3 years. Some elderly patients, due to physical conditions, age and other reasons, can not tolerate the removal of steel plate surgery or greater injury, at this time can not be removed.
