Fulminant heterotopic ossification after combat-related amputation: a report of 2 cases

Heterotopic ossification (HO) is the process of abnormal formation of lamellar bone in nonosseous tissues. In this case presentation, we describe patients with aggressive HO, which becomes symptomatic shortly after injury for which we have suggested the term "fulminant heterotopic ossification." These atypical presentations of fulminant HO highlight the necessity for continued research directed at improved understanding of HO and may suggest a role for early partial surgical excision as a definitive management strategy.
