I believe the answer is:

femoral

I'm a little stuck... Click here to teach me more about this clue!

'regarding upper leg of iron maiden it's said' is the definition.
I can't judge whether this definition defines the answer.

'iron maiden it's said' is the wordplay.
'iron' becomes 'Fe' (Fe is the chemical symbol for iron).
'maiden' becomes 'm' (cricket abbreviation).
'it's said' becomes 'oral' (I've seen this before).
'fe'+'m'+'oral'='FEMORAL'

Can you help me to learn more?

(Other definitions for femoral that I've seen before include "Of the thigh artery" , "Relating to the thigh bone" , "Of or near the thighbone" , "Lor, fame can relate to the thigh" .)

I've seen this clue in the Sydney Morning Herald.
