Introduction:

The hallux sesamoid are constant bones of small size and lentiform. They are located in the plantar region of the first metatarsal head within the capsule of the first metatarsophalangeal joint. The differential diagnosis of metatarsalgia over the first radius of the foot, without traumatic history, includes pathologies related to the sesamoids and others. Among the former are mainly sesamoiditis, stress fractures and avascular necrosis of the sesamoids.

Objective:

To report a case of sesamoiditis and its evolution after surgical treatment.

Case report:

This the case of a 25-year-old woman with a stress fracture of the fibular sesamoid. After serial infiltration with corticosteroids, it triggered a septic sesamoid necrosis, it was decided to perform a sesamoidectomy by plantar approach.

Conclusions:

Sesamoidectomy is a surgical option in degenerative processes of the sesamoids, when conservative treatments are insufficient. The plantar approach is considered adequate for removal of the fibular sesamoid. This technique requires adequate postoperative follow-up to optimize plantar healing.
