Info

The apophysis of the proximal 5th metatarsal lies laterally and is oriented longitudinally parallel to the shaft, in both sides.
Os naviculare is also evident, bilaterally.
Case Discussion
Apophysis of the fifth metatarsal base appears on plain radiographs before age 12 for boys and 10 for girls. The fusion of the apophysis to the metatarsal base usually occurs within the following 2-4 years. It should not be confused with an avulsion fracture particularly in a patient with a history of trauma.
