  • THERAPY OF THORACOLUMBAR VERTEBRA TUMOR BY TOTAL SPONDYLECTOMY AND SPINE RECONSTRUCTION THROUGH OSTERIOR APPROACH

    Objective To explore the surgical procedure and effectiveness of total spondylectomy and spine reconstruction through posterior approach to treat thoracolumbar vertebra tumor. Methods Between June 2004 and July 2008, 14 cases of thoracolumbar vertebra tumor underwent one-stage total spondylectomy through posterior approach and spine reconstruction with posterior pedicle screw system and bone graft. There were 11 males and 3 females with a mean age of 47.2 years (range, 36-60 years). The disease duration was 3-15 months. Affected segments included T3 in 1 case, T4 in 3 cases, T8 in 3 cases, T9 in 2 cases, T10 in 3 cases, T12 in 1 case, and L1 in 1 case. The postoperative pathological results were 3 cases of bony giant cell tumor, 1 case of osteoblastoma, 2 cases of osteosarcoma, and 8 cases of metastatic tumor. According to Tomita et al. grading system, there were 1 case of type II, 5 cases of type III, 3 cases of type IV, and 5 cases of type V. According to Frankel classification of preoperative spinal cord function, 3 cases were rated as grade B, 4 as grade C, 5 as grade D, and 2 as grade E. Results Wound heal ing by first intention was obtained in all cases, and no blood vessel and nerve injury occurred. Fourteen patients were followed up 11-64 months (mean, 32.5 months). The local pain was rel ieved significantly. At 6-8 months after operation, the X-ray films and CT showed that bone graft fusion at Bridwell I grade was achieved. At 10 months, the postoperative spinal cord function was improved from grade B to grade D in 2 cases, from grade C to grade D in 1 case, and the other 9 cases reached grade E. The patients had normal walking function. Two patients died of l iver metastasis and brain metastasis at 11 and 15 months postoperatively, respectively; 1 patient with osteoscarcoma died of lung metastasis at 16 months; and 1 case of osteoscarcoma developed local recurrence at 8 months postoperatively. Internal fixation was rel iable without loosening and breakage and the spine was stable. Conclusion Total spondylectomy and spine reconstruction through posterior approach is an effective method with advantages of relative minimal injury, radical tumor excision, low local recurrence, and adequate spinal cord decompression.

  • 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.
