For hand fractures steel pins are internal fixation devices that are placed to keep the fracture end aligned and stable, so the time of removal depends on the healing time of the fracture. When the fracture of the hand is healed, after about 2 months of examination and imaging to confirm that the fracture has healed, the internal fixation pins can be removed and functional training can be performed under the guidance of the physician. If the internal fixation is made with the bone plate screw system, the removal can be delayed because of the high strength and small rejection of this internal fixation, and it does not affect the functional training and hand function, so it is safer to consider removing the plate screw after 12 months. In elderly people with titanium plate fixation, the internal fixation titanium plate or titanium screw can be used for life without significant biological rejection, and therefore can be left in place.
