A Rare Case of Exostosis of the Medial Sesamoid Bone

Abstract

Introduction: Exostoses in the foot and ankle are extremely rare with no current literature of exostosis of the sesamoid bone. Case Report: A middle-aged woman was referred to orthopedic foot surgeons following a long-standing issue of a painful non-fluctuant swelling beneath her left hallux with normal imaging. Repeat X-rays, with sesamoid views of the foot, were conducted due to the patient’s ongoing symptoms. The patient underwent a surgical excision and made a complete recovery. The patient is now able to comfortably walk for longer distances with no restrictions to her mobility. Conclusion: Conservative management should be initially trialed to preserve the foot’s functions and limit the risk of surgical complications. As in this case, when surgical options are explored, it is critical to preserve as much of the sesamoid bone as possible to restore and sustain function.
