Sesamoid Stress Fractures

Stress fractures of the sesamoid occur in a wide variety of sports. They occur more frequently in the medial sesamoid though they may occur in either lateral or medial bone. They have a strong tendency for nonunion. Diagnosis would include imaging modalities as x-ray; Bone scan, and CT, as differential diagnosis, is often difficult. Treatment would be initially conservative with an orthosis preventing Hallux dorsiflexion and relative rest for 3–6 weeks, or cast for a similar period. Surgical treatment may eventually be needed to perform a bone graft or advance to partial or full excision of the injured bone.
