The best time to recover from a lumbar fracture in a 50 year old woman is within 8 weeks of the fracture. Women in their 50s are in the late pre-menopausal period, when the rate of calcium loss from the body begins to accelerate, but there should be no definitive effect on fracture healing. Typically, the most significant recovery time for lumbar fracture healing is within 8 weeks of fracture. After a fracture the body begins its repair mechanisms. The hematoma at the fracture site appears to mechanize, forming fibrous connections that gradually form a primitive bone scab that encircles the fracture site and maintains the stability of the fracture site. As the scab grows in abundance, it fills in the fracture space to form a bony connection until the fracture line disappears and the fracture reaches clinical healing. This healing mechanism is the fastest within 8 weeks, beyond which the fracture break will harden and the repair function will decline. Lumbar fractures need to be repaired at complete rest to achieve the fastest healing. Therefore, lumbar spine fracture, no matter conservative treatment or surgical treatment, after the fracture must be strictly bed rest, too much activity will cause the fracture to slow down the healing, or even non-healing.
