The apophysis of the proximal 5^th metatarsal (plural apophyses) lies laterally and is orientated longitudinally parallel to the shaft.

Apophysis of the fifth metatarsal base appears on plain radiographs at age 12 years for boys and 10 years for girls. Fusion of the apophysis to the metatarsal base usually occurs within the following 2-4 years ^3,4.

Differential diagnosis

It should not be confused with an os peroneum or an avulsion fracture. An avulsion fracture at this location is typically extra-articular and orientated transversally as compared to the longitudinal orientation of an unfused apophysis.
