62-year-old man with pain in the right midfoot.

Mild to moderate hallux valgus deformity.
Flattened fibular and tibial sesamoid grooves and Crista.
Moderate-sized juxtacortical osseous erosion at the medial aspect of the 1st metatarsal head, adjacent to the medial collateral ligament insertion. Mild to moderate arthrosis with slight marginal osteophytic spurring and joint space loss.
Marked tibial/medial sesamoid phalangeal arthrosis with flattening/osseous remodeling of the sesamoid groove. Moderate to marked fibular/lateral sesamoid phalangeal arthrosis with flattening and remodeling of the sesamoid groove. Flattened remodeled Crista.
Intact and unremarkable.
