Heterotopic Ossification Versus Myositis Ossificans

Hello All,

Can anyone clarify the difference between heterotopic ossification and myositis ossificans. I have had a frustrating evening searching the internet trying to figure out any differences. Some say that heterotopic ossification is just the revised name for myositis ossificans (doesn't just happen in muscle tissue and isn't always associated with inflammation). Others say that heterotopic ossification is the term used for neurogenic origin (e.g. post spinal cord injury). I have also heard that myositis ossificans has more to do with trauma to muscle tissue (e.g. quadriceps contusion, adductors in horse back riders). Please help.

Kevin,

My understanding was that heterotopic ossification was like an umbrella term that myositis ossificans falls under. Unfortunately I am not 100% certain.

Just tracked done a review article for you that confirmed my suspicions- enjoy.

Thanks a million for your response, and the attached article. I am a newly graduated physiotherapist and one of my biggest pet peeves is not understanding the medical language (and conversely, experienced therapists not being able to explain these subtle differences).

Cheers
Kevin
