Patients with lumbar fractures can get up, but depending on the patient’s specific situation, it is not advisable to get up too early. For patients with traumatic lumbar fractures, they generally sit up one and a half months after the fracture. Since the lumbar spine is basically cancellous bone with abundant blood, the fracture end grows relatively fast, but the lumbar part is not as strong as the extremities in weight bearing, so they must wait until there is significant bone scab growth at the fracture site. Generally, after the lumbar spine fracture has better blood flow, there will be obvious bone scab growth around the fracture end, and after six weeks, that is, one and a half months, the growth of bone scab will gradually mature and can bear a certain amount of weight, especially when sitting up, it can bear the upper body weight. Therefore, patients with lumbar spine fractures can sit up after one and a half months, but the time to start sitting should not be too long, so as not to lead to prolonged pressure on the fracture site, resulting in delayed fracture healing.
