The current popular prophylactic treatment modalities include non-steroidal anti-inflammatory drugs NSAIDs and radiation therapy although the literature remains inconclusive as to which is superior. Additionally both treatments can lead to adverse effects to the patient. Recently there have been several studies attempting to identify new aspects of the etiology of heterotopic bone formation and introduce new prophylactic modalities with increased efficacy and fewer side effects. For this review we selectively retrieved articles from Medline published from 1958-2008 on the prophylaxis of HO with the aim of assisting readers in quickly grasping the current status of research and clinical aspects of HO prophylaxis.
