Post-traumatic Myositis Ossificans Circumscripta

Abstract

A 66-year-old woman presented with painful gait and a large, firm, nonmobile mass in her right foot. She had undergone four previous surgeries to remove a recurring “calcified hematoma” that resulted from an injury sustained 3 decades previously. An unusually large ossific mass (7.0 × 7.0 × 2.0 cm) consistent with post-traumatic myositis ossificans circumscripta was excised. After 3 years of follow-up, there was no return of the symptoms or the mass. (J Am Podiatr Med Assoc 97(3): 229–233, 2007)
