Riddler cross after hips broken by Batman, finally (6)

I haven't cracked this one yet — but the brilliant team at Times for the Times have:

Anagram [broken] of HIPS + X (cross), containing [broken by] {Batma}N [finally]. The Riddle of the Sphinx is from Greek mythology and was supposedly put to to all those who passed through Thebes. The riddle is: What has one voice but goes on four legs in the morning, two in the afternoon, and three in the evening? AnswerThe answer to the riddle is a human being, who crawls as a baby, stands on two legs as an adult, and walks with a stick in old age.
