ABSTRACT

Introduction. The narrow lumbar channel is manifested by the progressive stenosis of the vertebral conduit as a result of the wearing down that appears by the age or in a column with degenerative changes. Objective. To determine the most frequent pathology in relation to the narrow lumbar channel. Material and methods. Retrospective study of the clinical file of 61 patients treated by narrow lumbar channel in the period of January 1, 2007 to July 31, 2009. Results. Spondylolisthesis was the most frequent pathology in relationship with narrow lumbar channel with predominance in female gender with 16 patients (59.2%), 11 (40.7%) in male; dominance of isthmic variety for a total of 21 patients with listesys at L5 S1 level (77.7%) and six patients at L4 L5 (22.2%). According to the classification of Meyerding most common levels were I-II. On disc herniations, there were 18 in male (69.23%) and eight in female (30.7%); about syndrome of degenerative narrow lumbar channel (SCLE): six male (75%) and two females (25%). The average age of diagnosis was 58 years old for males and 51 years old for female. The ages of presentation were in the rank of 20-88 years. According to the sort masculine predominance with 35 (57%) patients was observed, and 26 (43%) femenine. In the main pathologies: spondylolisthesis, 27 patients (44.3%); discal hernia, 26 (42.6%); 8 patients (13.1%), syndrome of degenerative narrow lumbar channel. Conclusion. According with our results the spondylolisthesis was the most frequent pathology in relation to the narrow lumbar channel with predominance in the women; more frequent at level L5 S1, followed of the level L4 L5; the isthmic variety was the most frequent, and degree I-II of the of Meyerding classification; but, there is no a statistically significant difference in comparison with the patients diagnosed with discal hernia. In the present study we collected data that agree with the reported in literature.
