Abstract
Heterotopic ossification is the abnormal formation of mature lamellar bone within extraskeletal soft tissues where bone does not exist. Heterotopic ossification has been classified into posttraumatic, non-traumatic or neurogenic, and myositis ossificans progressiva or fibrodysplasia ossificans progressive. The Brooker classification was proposed in 1973. Since then it has been used broadly for radiographic rating and for reporting the results of different prophylactic treatments for HO. It is a four class system based on Anteroposterior radiographic views.
