It is generally not recommended to remove the internal fixation after 100 days of internal fixation. For patients who choose surgical internal fixation, most of them are recommended to remove the internal fixation after one year. One hundred days after surgery for heel fracture is only the stage of fracture healing, removing the internal fixation at this stage may result in incomplete healing of the fracture. One hundred days after the operation of heel fracture, at this stage, most of them are from incomplete weight-bearing to full weight-bearing stage, which need the support of internal fixation, so it is not suitable to take out the internal fixation. In clinical practice, it is mostly recommended to take out the internal fixation after one year, and at the same time, it is also necessary to actively review the x-ray to determine the growth of the fracture, and for patients with delayed healing or even non-healing in clinical practice, it is necessary to appropriately prolong the time to take out the internal fixation. The specific time should be determined by the doctor.
