Heterotrophic Ossification in a Patient Suspected of Having Osteomyelitis

Abstract

A 46-year-old man, with a history of bilateral amputations, presented with a long-standing chronic nonhealing wound at the left below-knee amputation, which was sustained after a crush injury. The patient was referred for a bone scan to exclude osteomyelitis of the left stump. The bone scan showed increased uptake in the left below-knee amputation stump, raising the possibility of an infection. However, SPECT/CT of this area confirmed the uptake to correspond to the heterotrophic ossification of the left below-knee stump and no evidence of osteomyelitis.
