In the recent month, I was in charge of the emergency department of the orthopedic department of the Third Hospital. Looking back on the past nearly 10 years of emergency work experience, I always encounter many patients asking a similar question: How long do I need to treat a fracture? Today, let’s talk about this topic briefly. First, let’s understand the basics of the fracture healing process. The healing of a fracture includes the following three processes: Hematoma mechanization: This period can begin 6-8 hours after the injury, when local bleeding forms a hematoma around the fracture. After that, the body begins a complex series of processes to repair the injury site, a process that lasts until about 2 weeks after the injury. Primitive scab formation: After the first stage (hematoma mechanization), the body begins to try to form the initial scab, with the inner and outer scabs holding the tissue fibers from the hematoma mechanization in between, forming the typical “pike scab” seen on x-rays. This process often takes 4-8 weeks. For this reason, we often schedule the patient to have the x-ray reviewed at 2 and 4 weeks post-injury. Scab remodeling: This is the final stage of fracture healing, when victory is in sight. With the restart of limb activity and weight bearing, the repaired scab is remodeled to accommodate the body’s movement under stress, the scab is transformed into normal bone structure, and the medullary cavity is reopened, by which time we have passed 8-12 weeks. Knowing these basics, it is possible to understand the general purpose and stages of fracture recovery treatment. In the early post-injury period, prompt medical attention is needed to avoid repeated injury to the fracture end, to minimize bleeding to form an excessive hematoma, and to allow the body to enter the first phase: the hematoma mechanization phase, as early as possible. Afterwards, the fracture is immobilized for 4-6 weeks under the protection of a fixation device (cast/support/guard), during which we can determine the healing status of the fracture by x-ray. After that, patients who have recovered well can remove the external fixation and start rehab activities, allowing the newly repaired bone to be tested by the stresses, in which case the body will spend several weeks to complete the final “remodeling and shaping” by itself. This brings us to the answer to our original question: How long does a fracture usually take to recover? Simply put, it takes about 4-6 weeks of immobilization, followed by restorative exercise, and the entire fracture healing process is complete at 8-12 weeks post-injury. I would like to conclude by saying that clinical treatment is far more complex than what we have described above and that there are various different factors that can affect the healing of a fracture, some positive and some negative. More importantly, each patient’s injury and healing process is different and cannot be generalized. Therefore, the duration of treatment and the final outcome will vary for each individual. These topics will be explained slowly when we have time later.
