Back massage on street leads to rupture (5)
I believe the answer is:
burst
'rupture' is the definition.
(I've seen this in another clue)
'back massage on street' is the wordplay.
'back' says the letters should be written backwards.
'massage' becomes 'rub' (rub can mean to massage).
'on' says to put letters next to each other.
'street' becomes 'st' (abbreviation).
'rub' backwards is 'bur'.
'bur'+'st'='BURST'
'leads to' is the link.
(Other definitions for burst that I've seen before include "Pop" , "Fit" , "Exploded" , "Blow up" , "Rupture" .)
