compressed spinal column (collapsed spinal column)

collapsed spinal column - compressed
i do hope someone can help?

My son (aged 18) has been told his spinal column has collased at the bottom (lumber area i think). X-Ray shows this. He had an MRI scan which shows all is normal except compressed spine???

As per usual everything takes forever on the NHS...awaiting orthopaedic appointment but desperate to get some advice on it.

He was in hospital but now home because MRI was normal.

Can anyone help? Hes only 18, not been in an accident...just happened??? Hes a sporting person and cannot go to college now to finish his sports course or even work???

Help....arrghhhh worried mother !
