Epidemiology, neurological and functional outcome of concomitant traumatic brain and spinal cord injury: An Oswestry experience

Abstract

Background Concomitant traumatic brain injury with spinal cord injury is likely to worsen prognosis and increase hospital length of stay. This study assessed the duration of in-patient rehabilitation and outcome in patients with both traumatic brain injury and spinal cord injury. Methods Retrospective study of all patients with concomitant traumatic brain injury and spinal cord injury over a 3-year period who had 5 years of subsequent follow-up at the Midlands Centre for Spinal Injuries. Results Twenty-seven patients had concomitant injuries of which five had severe traumatic brain injury, nine had moderate traumatic brain injury and the remaining thirteen had mild traumatic brain injury with spinal cord injury of grades A–D; commonest mechanisms of injury were motor vehicle collision (55%) and falls (37%). Thirteen (48%) had tetraplegia and 14 (52%) had paraplegia. Mean functional independence measure score at admission was 52.1 and 103.4 at 5 years. Patients with mild traumatic brain injury gained a mean functional independence measure score of 67.1; the moderate and severe traumatic brain injury patients gained mean functional independence measure score of 60.1 and 69.2, respectively. The mean length of stay was 138.3, 139.4 and 153.4 days for mild, moderate and severe traumatic brain injury, respectively. Conclusion Hospital length of stay and patient’s functioning at 5 years were not affected by traumatic brain injury severity in this subgroup; however, functional independence measure on its own may not be very sensitive to cognitive deficits.
