[Nontraumatic spinal cord injury: etiology, demography and clinics].

We performed a retrospective and descriptive cross-sectional; study in 210 hospitalized patients with spinal cord injury at the National Institute of Rehabilitation (INR), Callao, Peru from 2000-2006. The goal was to describe etiology, and clinical and socio-demographic characteristics of non traumatic spinal cord injuries (LMNT). We found a prevalence of 27 % for LMNT, average age at onset of 32.0 years, male gender 50.5 %, and secondary education completed in 41.9 %, poverty 90.5 %. The infectious etiology (viral and bacterial) was predominant in 37.6 %, with 11.9 infected with HTLVI. Although the INR is a reference center, the findings can't be generalized because it isn't a representative sample of the Peruvian population, further studies are necessary to propose strategies for prevention and control, considering the high cost of integral rehabilitation treatment in these patients.
