@njx58 actually that’s not quite true in my case. My dexascan score was -4.5 at lumbar spine. However I am very small framed with no history of fractures ? Aged 75 yrs female . Been fit all my life . No history of fractures in mother or sibling. My surgeon recently performed L4/5 spinal fusion and told me my bones were strong !! I am eight weeks post op. I take fortibone and eat sensibly plus small calcium but D supplement. Can’t exercise at moment due to op . I still have fingers crossed but am hopeful .
