Lumbar spine fractures generally take 1 to 2 months at the earliest to form a visible bone scab. A small number of patients may have no scab formation after fracture, and the phenomenon of bone nonunion occurs. Under normal circumstances, the healing of the fracture, need to go through the following three periods, hematoma mechanization period, bone scab formation period, bone scab remodeling period; hematoma mechanization period is generally completed in about two weeks after the injury, while the bone scab formation period, which generally occurs in the post-injury period of 4 to 8 weeks to complete, so lumbar vertebral fracture formation of obvious bone scab generally need 1 ~ 2 months of time. A small number of patients after the fracture, hematoma mechanization absorption, delay in the formation of new bone scabs, and ultimately will appear the bone is not connected, usually need to carry out surgery and other methods of treatment. After the lumbar spine fracture, it is recommended to go to the hospital in time, follow the doctor’s instructions for standardized treatment, regular review, and follow the doctor’s instructions for activities, so as not to delay the condition.
