Finger dislocation immobilization steel pins are usually removed at 2 to 6 weeks. The exact time should depend on the degree of finger injury and recovery. Finger dislocation fixation pins generally refer to Kirschner’s pins, which can be used to fix the ends of the fracture to prevent displacement after the fracture is dislocated, and can be removed after the fracture recovers. If the finger injury involves thicker nerves or tendons, the pins can be removed in about 4 weeks and rehabilitation exercises can be carried out under the guidance of specialized physicians to restore the relevant functions. If the injury involves fracture or repair of small ligaments, the pins are usually removed at around 6 weeks. Removing pins too early or too late will affect the damaged part of the finger; too early and the damaged part will not heal completely, which may cause secondary injury; too late will affect the functional recovery of the finger joints, which may cause adhesion and stiffness. Therefore, the time of removing the steel needle for finger dislocation should be determined according to the different damaged parts and the recovery situation. Before removing the steel needle, X-ray examination should be done to determine whether the recovery situation is suitable for removing the steel needle.
