  • FUNCTION RECONSTRUCTION OF ANTERIOR AND MIDDLE COLUMN IN THORACOLUMBAR SPINAL TUBERCULOSIS BY ONE-STAGE ANTERIOR RADICAL DEBRIDEMENT

    Objective To summarize the effect of one-stage anterior debridement of infection in function reconstruction of anterior and middle column for the treatment of thoracolumbar spinal tuberculosis. Methods From January 2001 to January 2007, 65 patients with thoracolumbar spinal tuberculosis were treated with one-stage anterior debridement, decompression, autogenous bone grafts and internal fixation. There were 43 males and 22 females with an average age of 40.2 years (range, 19-64 years), including 18 cases of thoracic tuberculosis (T4-10), 44 cases of thoracolumbar tuberculosis (T11-L2) and 3 cases of lumbar tuberculosis (L3-5). The disease course was 3 months to 10 years (median 10 months). One segment was involved in 7 cases, two segments in 54 cases and three segments in 4 cases. In 14 cases with spinalcord injury, there were 5 cases of grade C and 9 cases of grade D according to Frankel classification. The kyphotic Cobb angle was 20-65° (41° on average). Results The operative time was 120-210 minutes (170 minutes on average), and the blood loss was 300-1 500 mL (600 mL on average). Fifty-eight patients were followed up for 1-6 years (23 months on average). Abscess occurred in 2 cases at 40 days and 3 months, and healed after symptomatic management. The other incisions achieved heal ing by first intention. The X-ray films showed bony fusion 4-12 months (6 months on average) after operation. No tuberculosis recurred. At 12 months after operation, pain disappeared, and there were 7 cases of grade D and 7 cases of grade E according to Frankel classification. The kyphotic Cobb angle was 0-33° (24° on average), showing statistically significant difference (P lt; 0.05) when compared with preoperation. Conclusion Early reconstruction of load-bearing function and stabil ity of anterior and middle column in the treatment of spinal tuberculosis is great significant. The appl ication of one-stage anterior surgery with debridement, decompression, autogenous bone grafts and internal fixation in the operative treatment of thoracolumbar tuberculosis is safe and effective after a rigorous anti-tuberculosis treatment.

  • PEDICLE SCREW FIXATION AND ALLOGRAFT BONE IN POSTERIOR SPINAL FUSION FOR TREATMENT OF THORACOLUMBAR VERTEBRAL FRACTURES/

    Objective To investigate the efficacy of the pedicle screw fixation and allograft bone in posterior spinal fusion for the treatment of thoracolumbar vertebral fractures. Methods From September 2006 to March 2008, 105 cases of thoracolumbar vertebral fractures were treated with allograft bone in posterior spinal fusion after the pedicle screw fixation,including 75 males and 30 males aged 15-65 years (mean 37 years). The mixture which consisted of spinous process and vertebral plate sclerotin and homogeneity variant bone was used as bone graft to implant into articular process and processus transversus space or vertebral plate space. The time from injury to surgery varied from 8 hours to 21 days, with an average of 3 days. There were 52 cases of fall ing injuries from height, 35 cases of traffic accident injuries, 11 cases of bruise injuries and 7 cases of tumbl ing injuries. Before operation, the primary cl inical symptoms of patients included local pain combined with l imitation of activity, 30 cases compl icated by various degrees of spinal cord and nerve root functional disturbance. According to Mcaffee classification, there were 7 cases of flexion depressed fractures, 86 cases of blow-out fractures, 9 cases of Chance fractures and 3 cases of dislocation-fracture. According to Frankel grade, there were 11 cases of grade A, 2 cases of grade B, 7 cases of grade C, 10 cases of grade D and 75 cases of grade E. The X-ray examination of all patients denoted that the bodies of injuryed vertebra were compressed and wedge-shaped, and the CT scan showed that 98 cases had spinal stenosis. After 2 weeeks and 3, 6, 12 months, the X-ray films were taken to evaluate bone graft fusion. The Cobb angle was measured. The recovery of nerve function was analyzed. Results The operation time was 55-180 minutes (mean 90 minutes) and the blood loss was 100-900 mL (mean 200 mL). All patients achieved heal ing by first intention with no compl ication. After operation, 93 cases were followed up for 6-15 months with an average of 11 months. Except for 11 patients who were at grade A before operation, one to two grade recover was observed in other patients. The average Cobb angle of injury segment was improved from preoperative 32.1° to postoperative 5.2°. The height of anterior border of injuried vertebral body was recovered from the preoperative average compressed remaining height 61.5% to postoperative 96.8%. The vestigial degree of canal is spinal is anteroposterior diameter was recovered from preoperative 65.7% to postoperative 89.9%. Imageology examination showed that all the patient achieved bone union within 6 months. The fusion rate of bone graft in spinal fusion was 100%. No loosening and breaking of nails occurred. Conclusion Pedicle fixators can restore and fix the thoracolumbar fractures, and the combination of autograft and allograft bone transplantation is a safe, rel iable and effective method.

  • COMBINATION OF INTENSIFIED ANTI-TUBERCULOSIS WITH OPERATION FOR TREATMENT OF THORACOLUMBAR TUBERCULOSIS

    Objective To evaluate the cl inical significance of the combination of intensified anti-tuberculosis treatment, posterior transpedicular screw system internal fixation, intertransverse bone grafting, and anterior approach focus debridement for the treatment of thoracolumbar tuberculosis. Methods From January 2005 to December 2007, 20 patients with thoracolumbar tuberculosis (T10-L3) were treated. There were 13 males and 7 females aged 21-64 years old (average 44 years old). The course of disease was 3 months to 3 years (average 10 months). The focus involved single vertebrae bodies in 8 cases, two vertebrae bodies in 9 cases, and three vertebrae bodies in 3 cases. The preoperative Cobb angle was 9-35° (average 26.7°). The neurological function was evaluated according to the Frankel grading criterion, there were 2 cases of grade B, 5 of grade C, 7 of grade D, and 6 of grade E. Vertebral body defect index score: 9 cases of 1-2 points, 7 cases of 2-3 points, and 4 cases above 3 points. After receiving the systemic five-drug treatment of anti-tuberculosis for 2-3 weeks, the patients underwent the posterior transpedicular screw system internal fixation and intertransverse bone grafting, and then received tuberculosis focus debridement via anterior approach, nerve decompression, and bone grafting fusion. Results The time of operation averaged 210 minutes and the mean blood loss during operation was 650 mL. Postoperatively, 2 patients had mild belting sensation in their thorax and 2 patients had mild pneumothorax. Their symptoms rel ived 2-3 weeks later without specific treatment. All the patients were followed up for 12-23 months. X-ray films showed that all the patients achieved successful bony fusion 6-18 months after operation, and the Cobb angle was 7-21° (average 15.2°) 12 months after operation without aggravation. The Frankel gradingsystem was used to assess the postoperative neurological function, 1 patient in grade B before operation was improved to grade C after operation, 1 patient in grade B was improved to grade D, 1 patient in grade C was improved to grade D, 4 patients in grade B were improved to grade E, and 7 patients in grade D were improved to grade E. All of the incisions healed and erythrocyte sedimentation rate became normal 2 weeks to 3 months after operation. All the patients showed no obvious abnormity in l iver and kidney function. There was no recurrence of tuberculosis. Conclusion It seems that the systemic drug treatment of antituberculosis before and after operation, the thorough debridement of focus during operation, and the effective and rel iable wayto reconstruct for the spinal stabil ity are the key points for the treatment of spinal tuberculosis.
