Os interphalangeus is an ossicle present in the plantar aspect of interphalangeal joint of great toe 1. The ossicle can be present either centrally or eccentrically within the joint capsule and is separated from the flexor hallucis longus tendon by a bursa.
Bone is ossified in ~7.5% (range 2-13%) of individuals, which can be visible on plain radiographs.
If symptomatic, management is usually conservative with anti-inflammatories and orthotic support. Surgical excision can be considered for refractory cases 2.
