'aponeurotomy' originates from Greek elements: 'apo-' meaning 'away, off', 'neuron' meaning 'sinew' or 'tendon', and '-tomy' from 'tomē' meaning 'cutting'.

'aponeurotomy' is a modern medical formation derived from New Latin/Greek medical compounds: from Greek components 'apo-' + 'neuron' + '-tomia', passed into New Latin/medical usage and adopted into English in medical contexts as 'aponeurotomy.'

Initially coined to denote the act of cutting an aponeurosis, its meaning has remained specialized and refers specifically to that surgical procedure.
