Total heterotopic ossification of an acellular dermal matrix used for abdominal wall reconstruction.

Heterotopic ossification is an observable phenomenon in the setting of abdominal wounds, estimated to effect 25% of all patients after midline abdominal surgery. The development of acellular dermal matrices has revolutionised the approach in repairing abdominal hernias, especially for potentially contaminated wounds. We describe a case of heterotopic bone formation incorporating the whole of an acellular dermal matrix in a patient on chronic steroid therapy.
