RESUMO
<p><b>OBJECTIVE</b>To evaluate the clinical effects of CT-guided percutaneous puncture and local chemotherapy for lumbosacral spinal tuberculosis.</p><p><b>METHODS</b>From January 2002 to March 2013, 145 patients (84 males and 61 females) with lumbosacral spinal tuberculosis underwent failed conservative treatment were treated with CT-guided minimally invasive surgery. Their clinical data were retrospectively analyzed. Among them, 143 patients were followed up, aged from 2.5 to 81 years with an average of (42.60 +/- 17.14) years. Fourteen cases (6 cases with internal fixation and 8 cases without internal fixation) recurred and 32 cases complicated with paraspinal abscess after operation. Preoperatively 1 case complicated with lower limb weakness and superficial sensation worse, 1 case with muscle strength decrease, this 2 cases were grade D of Frankle, other cases were grade E. And 1 patient underwent fenestration operation and local chemotherapy, 144 cases with CT-guided percutaneous puncture and local chemotherapy. ESR and lumbar lordosis angle of all patients were observed preoperatively and final follow-up.</p><p><b>RESULTS</b>The mean follow-up time was 67 months (ranged, 21 to 149 months) in 143 cases, and 73 cases more than 5 years. All patients obtained clinical healing. ESR was (44.96 +/- 12.41) mm/h before operation and (7.25 +/- 3.43) mm/h at final follow-up, there was significant difference between preoperative and postoperative (t=35.06, P=0.000). Lumbar lordosis angle was (36.32 +/- 8.55) degrees before operation and (33.35 +/- 8.16) at final follow-up, there was significant difference between preoperative and postoperative (t=13.90, P=0.000).</p><p><b>CONCLUSION</b>When conservative treatment fails for 3 months or more, the patients have good spinal stabilization, nerve function is more than grade D of Frankel, CT-guided percutaneous puncture and local chemotherapy can get satisfactory outcomes for lumbosacral spinal tuberculosis.</p>
