Still breaks hip (8)
I believe the answer is:
snapshot
'still' is the definition.
(I've seen this before)
'breaks hip' is the wordplay.
'breaks' becomes 'snaps' (snapping is a kind of breaking).
'hip' becomes 'hot' (hot can mean hip or trendy).
'snaps'+'hot'='SNAPSHOT'
(Other definitions for snapshot that I've seen before include "Informal photograph" , "print" , "image" , "Instant record of an event" , "still taken quickly" .)
