Back part getting write-up in chiropractors' journal? (6,6)
I believe the answer is:
spinal column
'back' is the definition.
(I know that back can be written as spinal column)
'part getting write-up in chiropractors' journal?' is the wordplay.
I cannot quite understand how this works, but
'part' could be 'pin' (pin is a kind of part) and 'pin' is found in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for spinal column that I've seen before include "Vertebral structure" , "Backbone" .)
