Lumbar spine fractures are generally recommended for 4-6 weeks before exercising to climb stairs. The lumbar spine is the most frequent site of spinal fractures, with lumbar 1 and 2 being the most common. Because lumbar 1 and 2 are located at the junction of the thoracic and lumbar spine, they are the junction of the stable thoracic spine and the movable lumbar spine, and the spinal stress is concentrated here, so fractures are more frequent in this area. The treatment of lumbar fractures differs according to the degree of injury, and is divided into surgical treatment and conservative treatment. If the fracture is more severe and results in loss of lumbar stability, surgical internal fixation is required to rebuild lumbar stability. In this case, because of the implantation of a strong internal fixation, a new stable system is quickly formed in the lumbar spine, so that early functional exercises can be performed on the ground. Walking exercises under the protection of a spinal support can be performed 2-3 weeks after surgery, and you can gradually practice walking up and down stairs, but do not overexert yourself. If the fracture is mild and the stability of the lumbar spine is still good, then conservative treatment is possible, but conservative treatment requires at least 4 weeks of bed rest, and without surgery at least 4 weeks before you can go down to the ground, and as for going up and down stairs, it is better after 6 weeks.
