First lumbar compression fracture 1/3 after six months of conservative treatment is not recommended to do heavy work, because it may lead to re-injury of the lumbar region. Compression fracture of the first lumbar vertebrae refers to the compression of the vertebral body caused by external force on the first lumbar vertebrae, which is manifested by localized swelling and pain and limited lumbar activities, partly caused by violent injuries, such as traffic accident injuries, falling injuries and so on. If the patient suffers from osteoporosis, metabolic bone disease, etc., the first lumbar vertebral compression fracture may be caused by a slight external force. Under normal circumstances, a compression fracture of the first lumbar vertebra usually takes at least 4 to 6 months to recover, but heavy work can easily lead to lumbar injuries, especially in the case of osteoporosis, etc., so it is not recommended to do heavy work. It is recommended to go to the hospital in time, and under the guidance of the doctor to carry out relevant examinations to clarify the physical condition.
