OBJECTIVETo investigate the effectiveness of anterior debridement,bone graft, and posterior pedicle screw-rod internal fixation in the treatment of lumbosacral tuberculosis.
METHODSFrom January 2005 to June 2012,18 patients with lumbosacral tuberculosis undergoing the surgical treatment by anterior debridement, bone graft, and posterior pedicle screw-rod internal fixation were reviewed retrospectively. There were 12 males and 6 females with an average age of 44 years old ranging from 35 to 67. Among them, 2 cases were simple low back pain,3 cases were low back pain combined with radiating pain of lower extremity and 13 cases were muscle strength hypesthesia. According to Fankle grading,the nerve function was grade C in 3 cases,grade D in 10 cases,grade E in 5 cases. Of these cases,L4.5 was involved in 8 cases,L5 in 4 cases and L5S1 in 6 cases. The lumbosacral angle was 150 to 270 and the erythrocyte sedimentation rate (ESR) was 45 to 93 mm/h before treatment. The clinical indexes including the lumbosacral incidence, Frankel grade and ESR were reviewed at follow-up.
RESULTSAll 18 cases were followed up for 14 to 22 months. The mean operation time was 180 min. The amount of bleeding was 400 to 800 ml. Except 1 case with iliac vein injuried and 4 cases with abdominal distension,no spinal injuries and severe relative complication occurred, and neurologic function improved in various degrees. Pain in lumbosacral area and radicular pain in lower extremities disappeared. The X-ray and CT films demonstrated that bony fusion was obtained in all patients during 9 to 13 months postoperatively. The lumbosacral angle and ESR were improved significantly.
CONCLUSIONAnterior debridement, bone graft, and posterior pedicle screw-rod internal fixation is an effective method in dealing with lumbosacral spine tuberculosis.
