Spinal cord injury is infrequent from infancy to pre-adolescence. The incidence of traumatic lesions of the infantile spinal cord in relation to all age groups oscillates between 0.65% and 11%. Spinal injuries in relation to mild head injuries are 1 / 25-30, and severe head injuries are 1/20; However this incidence may not be as reliable because the statistics are not including minor problems or those that are not hospitalized or survive before reaching the hospital. Cirak et al. have recently studied 406 children under 14 years of age with spinal trauma, with 4% of the total number of patients admitted to the hospital.
The age of 5 to 14 years was predominant in the 36 cases studied. From the study by Cirak et al the average age was 9 years. It has been observed a higher incidence of males in a ratio of 2-3: 1 compared to the female sex; This difference is remarkable in10 years old. This is due to the greater concern, carrying out activities that demand greater risk (sports practice, driving motor vehicles, etc.) and drug consumption by older children and adolescents. On the other hand we have observed that these traumatic problems of the rachis and marrow occur mainly in the evenings and nights. Ducker and Perot report that in their cases studied at night and dawn were the predominant moments.
