An os vesalianum pedis is an accessory ossicle of the foot. Although asymptomatic, it may become symptomatic occasionally, causing lateral foot pain and requiring surgical excision ².

Gross anatomy

It is formed as a result of failed fusion of the secondary ossification center of the metatarsal. It is situated at the base of the fifth metatarsal in the peroneus brevis tendon ¹.

Differential diagnosis

in children it should be differentiated from the apophysis of the fifth metatarsal
base of the fifth metatarsal fracture
os peroneum
Iselin disease
Jones fracture
stress fractures
