Sutures
'sutures' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for stitches that I've seen before include "Spasms of pain, caused by needles?" , "Sews" , "Sharp spasms of pain in the side" , "Movements of threaded needle in fabric" , "Sharp pains in the side caused by running" .)
