Aims Heterotopic bone can cause restriction of movement when deposited in the soft tissues around joints. Neurogenic heterotopic ossification may follow brain injury. This article describes research into the incidence of heterotopic ossification after brain injury, and its impact on rehabilitation. Methods Thirty-nine patients who were admitted to the rehabilitation unit of University Hospital Bydgoszcz, Poland, after hypoxic brain injury due to cardiac arrest, were examined. Findings Six patients were identified as having developed heterotopic bone around one or more joints causing limitation of movement and delay in the rehabilitation process. Conclusions Heterotopic ossification occurs in up to 15% of patients following hypoxic brain injury. The development of the condition may often be missed clinically, and can hinder rehabilitation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
