Background: Heterotopic ossification (OH) is a complication described in patients with neurological damage. Case report: Patient who suffered a multiple trauma and traumatic brain injury (TBI), with fractures and neurological deficit secondary to TBI, who presented several heterotopic ossifications (OH) during his evolution that compromised the achievement of functional objectives.
