Preoperative punction CT-guided was performed in 51.7% of patients. It was positive in 26.7% of those patients. Blood cultures were positive in 29.4% and intra-operative culture was positive in 53% of the pyogenic spondylodiscitis. Staphylococcus aureus was the most common organism. The averaged onset of symptoms-surgery period was 6.75 months in tuberculous spondylodiscitis and 3.2 months in pyogenic spondylodiscitis. Double-level spondylodiscitis was observed in 41.4%. The spinal region most frequently affected by spondylodiscitis was the thoracolumbar and lumbar spine in 66% of cases. All of the patients with incomplete neurologic impairment showed improvement after surgery. There were no recurrences of infection. There was a statistically significant difference (p=0.011) in the loss of correction of saggital angle: more loss of correction in Group II 7.07° (range, 0°–17°) than in Group I 1.8° (range, 0°–5°). The saggital angle preoperative/postoperative/3 months postop/6 months postop/12 months postop/ Final was: 14.42° /1.96° /2.75° /2.83° /2.92° /3.75° (means) in Group I. −7.57°/–8.43°/ −3.21°/ −1.71°/ −1.93°/ −1.36° in Group II (in this group, there was a significant loss of correction between inmediate postoperative-3 months postop and 3 months postop-6 months postop). There were statistically significant differences in operative time and in blood loss (more in Group I). The preoperative Visual Analogic Scale score averaged 9 in Group I and 9 in Group II and improved to 2.4 and 2.33 after surgery, respectively.
