Typically, the exposed Kirschner pin needs to be removed after 4-6 weeks of fixation. Clinique pins are a common method of external fixation of fractures in orthopedics and are commonly used for external fixation of hand and foot fractures. Fractures such as finger fractures, palm fractures, and toe fractures have a short healing time, usually 4-6 weeks after scab formation and initial fracture healing, at which time the Kirschner pins can be removed. Some of the Kirschner pins are exposed to air and prolonged fixation may cause infection of the skin and soft tissues, or even bone infection, leading to serious consequences. Therefore, it is necessary to remove the Kirschner pins after the initial healing of the fracture. The fracture should be reviewed regularly during the healing period in the hospital, and the fracture should be treated promptly if it is found to be misaligned, locally red, swollen and painful. Patients with fractures should strengthen nutrition, eat a light diet, and should perform functional exercises of the bone and joint under the guidance of a doctor to prevent adhesions from occurring in the joint and affecting the bone and joint activities.
