To evaluate the method and effectiveness of anterior focus clearance with autograft bone fusion and internal fixation in treating of adjacent multivertebral tuberculosis in one-stage. Methods Between March 2007 and September 2009, 8 cases of thoracic vertebra tuberculosis were treated. Of 8 cases, 6 were male and 2 were female, aged 32 years on average (range, 20-42 years). The disease duration ranged from 8 to 14 months (mean, 10.2 months). Affected vertebrae included thoracic vertebrae in 35 cases and lumbar vertebrae in 11 cases; 5 vertebrae were involved in 4 cases, 6 vertebrae in 3 cases, and 8 vertebrae in 1 case. According to Frankel classification, there were 2 cases of grade C, 4 cases of grade D, and 2 cases of grade E. All patients had different kyphosis with the Cobb angle of (25.1 ± 6.6)°. All patients received antituberculous therapy 4-6 weeks preoperatively; after complete clearance lesions, autograft bone fusion and internal fixation were performed, and then antituberculous therapy was given for 18 months. Results All incisions healed by first intention. Eight patients were followed up 18-48 months (mean, 29 months). According to JIN Dadi et al. criterion, 7 cases recovered after first operation, 1 case of relapsed tuberculosis with sious was cured after re-focus clearance. The Cobb angle was (19.5 ± 4.2)° at 7 days after operation and was (22.3 ± 3.6)° at last follow-up, showing significant differences when compared with the preoperative value (P lt; 0.05). The nerve function of all cases were classified as Frankel grade E. CT scan showed bone graft fusion at 6-8 months after operation. No loosening or displacement of grafted bone and internal fixation occurred during follow-up. Conclusion The treatment of adjacent multivertebral tuberculosis by anterior focus clearance, intervertebral autograft, and internal fixation in one-stage is effective. Anterior bone fusion and internal fixation in one-stage can correct kyphosis effectively and rebuild spinal stabil ity, so it is a good choice for surgical treatment of adjacent multivertebral tuberculosis.
ObjectiveTo evaluate the safety and effectiveness of one-stage posterior surgery via unilateral musculussacrospinalis iliac flap approach in treatment of lumbosacral tuberculosis.MethodsBetween August 2011 and October 2014, 13 patients with lumbosacral tuberculosis were treated by one-stage posterior reserved posterior ligament complex, lesion debridement, bone graft fusion, and internal fixation via unilateral musculussacrospinalis iliac flap approach. There were 8 males and 5 females, aged from 22 to 57 years, with an average age of 35 years. The disease duration ranged from 2 to 19 months, with an average of 6.7 months. According to the American Spinal Injury Association (ASIA) classification criteria, the patients were graded as grade B in 2 cases, grade C in 4 cases, grade D in 5 cases, and grade E in 2 cases before operation. The preoperative Oswestry disability index (ODI) was 36.4±5.7; the preoperative lumbosacral angle was (20.7±0.7)°; the preoperative erythrocyte sedimentation rate (ESR) was (63.4±8.4) mm/1 h; and the preoperative C-reactive protein (CRP) was (38.8±5.2) mmol/L. The operation time and intraoperative blood loss were recorded. The ODI, ASIA grade, lumbosacral angle, and ESR were recorded at last follow-up. Bridwell criterion was used to judge the interbody fusion.ResultsThe operation time was 150-240 minutes (mean, 190 minutes), and the intraoperative blood loss was 420-850 mL (mean, 610 mL). No major blood vessel, dural sac, nerve root, and lumbosacral plexus injuries occurred during the operation. Delayed wound healing occurred in 3 cases, and primary wound healing achieved in the other patients. No wound infection or sinus formation was found. All 13 patients were followed up 1.5-6.1 years (mean, 2.8 years). During the follow-up period, there was no tubercular symptom, cerebrospinal fluid leakage, loosening and rupture of internal fixator; and no complications such as retrograde ejaculation and erectile dysfunction occurred in 8 male patients. Solid spinal fusion obtained in all patients with the mean fusion time of 6.4 months (range, 4.2-9.9 months); and all iliac osteotomies healed. At last follow-up, the ODI was 7.2±3.5, the lumbosacral angle was (31.2±0.5)°, and ESR was (9.8±2.5) mm/1 h, all of which improved significantly when compared with pre-operative ones (P<0.05). The patients were classified as grade D in 2 cases and grade E in 11 cases, which improved significantly when compared with preoperative ones (Z=–3.168, P=0.002).ConclusionOne-stage posterior surgery via unilateral musculussacrospinalis iliac flap approach in treatment of lumbosacral tuberculosis is effective and safe.
