The removal of internal fixation after a fracture should be based on the following principles: Has the fracture grown? Generally speaking, the fracture can be healed within a specified period of time with the help of internal fixation devices. The principle of removal of internal fixation is to wait until the fracture is well and firmly established. Usually, the recommended time for removal of internal fixation is 6 to 12 months after surgery in children. Also, the type of internal fixation device and the site of implantation are important factors in determining whether and when to remove the implant. Not all implants must be removed due to the different roles of the implants, e.g., spinal implants are usually not removed. If the implant is buried deep or near a critical nerve or blood vessel, the risk of removing the implant may be greater than the safety of permanent retention in the body, and removal is not recommended. In addition, if the implant has been in place for too long, it is generally not recommended to remove the implant if it has been in place for more than 2 years, because the damage to the tissues surrounding the implant may be significant at that time. For your child’s ulnar hawkbone fracture, a plate or tension wire is usually applied, and if it has been more than 6 months, it may be considered for removal.
