After a traumatic injury, if a fracture is considered a possibility, it is important to review it regularly, whether or not it is clear at the first visit. This is because (1) Some early manifestations of fractures (including one’s own sensation and x-ray performance) may not be obvious. The fracture line only becomes clear several days later as the fracture end is absorbed. (2) After the fracture has been fixed in a cast or splint, the fracture may be displaced after a few days as the swelling of the fracture site gradually subsides and the external fixation becomes relatively loose. Timely review will enable timely detection and treatment. (3) Fractures and various treatments have various possible complications inherent to them, and regular review helps to detect and manage them in a timely manner. (4) Any examination means has to go through many steps such as machine operation, image acquisition, personnel interpretation, etc. It is impossible to completely avoid errors, which means there is a certain false positive rate and false negative rate. It is sometimes not objective and accurate to conclude the presence or absence of a fracture in a single examination. It is not uncommon for similar cases to result from neglecting the importance of periodic review. A patient who was bruised by a car was not sure of the fracture at the first visit and was recommended to be reviewed in 3 days. The patient did not care and did not review the patient on time, and thought there was no fracture and settled the case with the perpetrator at that time. Later, when the pain increased, the patient came for a review and the X-ray showed a fracture that required a cast and a period of inability to work. In other fracture patients, the fracture alignment was very good after the first manipulation and cast fixation, and the doctor also recommended a review after 3 and 10 days. However, the patient felt that the cast was well fixed and there was no abnormal sensation, so he did not review the fracture to avoid trouble, only to find out more than a month later that the fracture had been displaced and missed the opportunity to reset it by manipulation, so he had to receive surgery. The lesson is not a bad one. The most common type of fracture is the fracture of the distal radius of the forearm (e.g. Colles fracture), which is common in the elderly, and often the first manipulation can achieve good results, but if the fracture is not reviewed and replaced with a cast fixation in 1 week or 10 days, a significant proportion will be re-displaced. If reviewed in time, there is a possibility of effective conservative treatment with timely repositioning within 2 weeks or so. If this happens in children, the consequences may be worse, because pediatric fractures generally have more bone scabs attached in about two weeks, making repositioning more difficult, and once the deformity has healed, it will have a negative impact on further development. With this knowledge, it is easy to understand why doctors recommend that patients come in for regular follow-ups after an injury, and in most cases, additional x-rays are needed. If you know the above, you should pay more attention to the fact that you should not give up the regular checkups recommended by the doctor because of the inconvenience of mobility or because you feel good.
