Background: Pure traumatic spinal cord injury (without associated bone lesion) are encountered in pediatric accidentology, the most typical being spinal cord injury without radiological abnormality (SCIWORA). The present study reports a multicenter series of under-18-year-olds admitted for traumatic medullary lesion. The objectives were: (1) to describe the causes of pure spinal cord injuries in children in France and their clinical presentation; (2) to identify any prognostic factors; and (3) to describe their medical management in France.
Patients and method: A multicenter retrospective study was conducted in 3 pediatric spine pathology reference centers. Files of 37 patients with confirmed spinal cord injury between January 1988 and June 2017 were analyzed: SCIWORA (n=30), myelopathy associated with severe cranial trauma (n=2), and obstetric trauma (n=5). Accident causes, associated lesions, initial Frankel grade, level of clinical spinal cord injury, initial MRI findings, type of treatment and neurology results at last follow-up were collated. The main endpoint was neurologic recovery, defined by improvement of at least 1 Frankel grade.
Results: Causes comprised 17 road accidents, 11 sports accidents, 5 obstetric lesions and 4 falls. Mean follow-up was 502 days. The rate of at least partial neurologic recovery was 20/30 in SCIWORA, 0/5 in obstetric trauma, and 0/4 in case of associated intracranial lesion. In SCIWORA, factors associated with recovery comprised age, accident type, and absence of initial MRI lesion.
Discussion: We report a large series of pediatric spinal cord injury without associated bone lesion. This is a potentially serious pathology, in which prognosis is mainly related to age and trauma mechanism.
Level of evidence: IV, case series.
