[Value of ultrasound in diagnosis of post-traumatic heterotopic ossifications]

Heterotopic ossification is a non-neoplastic deposit of bone within soft tissue (myositis ossificans). The most common localized form is post-traumatic myositis ossificans. The ultrasonographic appearance of heterotopic ossification is characterized by highly echogenic areas with attenuation or complete disappearance of the acoustic signal distal to these areas. The size and extent of para-articular ossifications can also be evaluated, and the choice of the surgical approach is facilitated and damage to soft tissue minimized by the ultrasonographic examination.
