[en] Introduction: Non-traumatic spinal cord injury includes diverse etiologies within which we find the canal stenosis. We define spinal stenosis as a structural narrowing of the spinal canal, lateral recesses and conjunct holes. The degenerative changes that cause the progressive narrowing of the canal and the vertebral holes can lead to radiculopathies and myelopathies, these being more frequent at the cervical and lumbar level. The aim of the study is to describe the demographic characteristics of nontraumatic spinal cord injuries, due to canal stenosis, framed in our hospital, studying neurological evolution and outcome measurements upon discharge, after rehabilitation treatment. Material and Methods: A retrospective descriptive study will be carried out, assessing the patients admitted with non trumatic - spinal cord injury , after surgical intervention of canal stenosis and herniated disc, in the Spinal cord Injury Unit of the A Coruña's Hospital. The period between January 1995 and December 2018 will be analyzed. The demographic and clinical characteristics, the rehabilitation therapy, the functional outcomes, and WISCI will be analyzed. Results and Discussion: The etiology of spinal cord injury was spinal stenosis in 62% of the cases, and herniated disc in 37.7% with an average age of 65 years, and 54 years respectively. In 70% of the global sample of patients there was an improvement of the score of the motor index on discharge with respect to income, in 26.3% it remained and in 3.8% the score of the MI was worst. The mobility and the ability to march (WISCI) was related to ASIA grade, motor index and etiology. (p <0.005).

[gl] Introdución: A lesión medular non traumática inclúe diversas etioloxías nas que atopamos a estenosis da canal. Definimos a estenosis do canal dexenerativo como un estreitamento estrutural da canal espiñal, recesos laterais e / ou buratos conxunción. Os cambios dexenerativos que provocan o estreitamento progresivo da canal e os buracos vertebrales poden conducir a radiculopatías e mielopatías, que son máis frecuentes a nivel cervical e lumbar. O obxectivo do estudo é describir as características demográficas das lesións medulares non traumáticas, debidas á estenose de canal, enmarcadas no noso hospital, estudando a evolución neurolóxica e os resultados funcionais tras a alta, despois do tratamento de rehabilitación. Material e Métodos: Levarase a cabo un estudo descritivo retrospectivo que avalía aos pacientes ingresados con lesión medular de orixe médica, logo da intervención cirúrxica da estenose do canal e hernia discal, na Unidade de Lesionados Medulares do hospital da Coruña. Analizarase o período entre xaneiro de 1995 e decembro de 2018. Analizaranse as características demográficas e clínicas, a intervención rehabilitadora, os resultados funcionais, e WISCI. Resultados e discusión: Dos pacientes a estudio, a causa da lesión medular foi a estenose do canal no 62% dos casos e a hernia do disco no 37,7%, cunha idade media de 65 anos e 54 anos, respectivamente. No 70% da mostra global de pacientes, produciuse unha mellora da puntuación do índice motor (IM) no momento da alta respecto ao ingreso, nun 26,3% mantívose, e nun 3,8% a puntuación do IM empeorou. A mobilidade e capacidade para camiñar (WISCI) atópase relacionado co nivel de ASIA, o IM e a etioloxia. (p <0,005).
