Early Ultrasound Screening of Heterotopic Ossification After Severe Neurological Trauma

Prospective, bi-centric diagnostic, performance study on a new diagnostic procedure with ultrasounds against a reference diagnostic procedure. The primary objective is to study the performance of ultrasound coupled with clinical examination at 1 week of admission for early screening of heterotopic ossification (HO) in patients admitted to a post intensive care rehabilitation unit (PICRU) after a severe neurologic trauma. The CT scan at 5 weeks of admission is considered as the gold standard. CT scan reader will be blinded to clinical data.
