An observational descriptive study of 35 patients operated on of herniated lumbar disc by microsurgery techniques from February, 1996, to February, 1997, was conducted. 68.57% of these patients were males and 31.43% were females, with an average age of 42.11 and an age range between 23 and 74. The diagnostic methods that influenced on the surgical decision were lumbar myelography with hydrosoluble contrast in 37.l4% and CAT in 34.28%, whereas electromyogram (EMG), the clinic and simple X-rays were less determining 20 % and 14.29 %, respectively. The spaces L5-S1 (57.14%) and L4-L5 (31.43%) were the most affected. The combination of both was observed in 11.43%. The most frequent complication was herniated disc (8.57%). Average hospital stay was 2.79 days, 48.57% with less than 24 hours (ambulatory surgery). The surgical results at 6 months according to Ebeling’s scale were satisfactory in 97.l4% of the cases with 57.l4% classified as good; 31.43%, excellent; 8.57%, fair and only 2.86%, poor. The technique did not fail in any of the cases.
