On average, how long will a t12 fracture in my back heal?

3-4 month: It depends, what kind fracture is it and if you have any complications with it.

Take it easy: Most spine fractures will heal within 3 months with bracing, limiting strenuous activity and close follow-up with a spine specialist. Some fractures require surgical stabilization and kyphoplasty is an option for elderly patients with compression fractures. Check out spine-health.Com.
