Fractured t10 vertebrae 8 months ago. no degree of healing on x-rays. bone density tested but i'm only 25. is there other possibilities as to why?

Fracture: Very uncommon at your age but depends on your growth. Even more uncommon are vertebral fractures that occur during pregnancy or shortly after. Regrettably you also need to make sure the technician and the doctor who report the data have been properly trained. Fewer than 25% of techs and even fewer docs have been properly ttrained. Sad but true.

A traumatic: fracture can occur with normal bone density. Did you have significant trauma? Patients with abnormally low bone density are at risk for stress and insufficiency fractures, but anyone can get a fracture from trauma. Once a vertebral body sustains a compression fracture, it never regains its normal height. It will heal maintaining the compression deformity.
