Base of 5th metatarsal fracture and apophysis

Discussion:

This case illustrates the difference in the appearance of an avulsion fracture and an apophysis at the base of the 5th metatarsal, as both are present simultaneously in this 10 year old patient. The avulsion fracture line is oriented horizontally or transversely across the base of the metetarsal whilst the lucent cartilage line of the normal apophysis is always oriented longitudinally.
