Lumbar vertebral fracture generally about 3 weeks after the beginning of the formation of fibrous bone scab, but the strength of the fibrous bone scab is not enough, in the subsequent 2 months or so, the fibrous bone scab gradually calcification, shaping, the formation of a relatively strong bony scab. Lumbar vertebra is mainly cancellous bone, compared with the limbs rod bone blood flow is more abundant, generally about 8 weeks after the injury of the vertebral body of the bone scab has a certain degree of stability, this time the patient can wear lumbar support or belt gradually get out of bed activities. However, patients must be instructed not to do bending and other work and life, because the vertebral body is mainly based on cancellous bone, about 8 weeks of the vertebral body compression resistance is still relatively poor, if engaged in bending activities, may lead to vertebral fracture compression aggravation, the formation of secondary injury. Therefore, lumbar vertebral fracture scab formation time is early, about 3 weeks there is a fibrous scab formation; about 8 weeks there is a relatively mature bony scab formation; about 10-12 weeks the scab shaping is completed, the elderly osteoporosis patients need to appropriately extend the time of scab formation.
