    ABSTRACT: PURPOSE: The purpose of this study is to compare the clinical outcomes of surgical management by one-stage posterior debridement, transforaminal lumbar interbody fusion (TLIF) and instrumentation and combined posterior and anterior approaches for lumbar spinal tuberculosis, and determine the clinical effectiveness of the posterior only surgical treatment for lumbar spinal TB at the same time. METHODS: Thirty-seven patients who suffered lumbar tuberculosis were treated by two different surgical procedures in our center from May 2004 to June 2012. All the cases were divided into two groups: 19 cases in Group A underwent one-stage posterior debridement, TLIF and instrumentation, and 18 cases in Group B underwent posterior instrumentation, anterior debridement and bone graft in a single-stage procedure. The operation time, blood loss, lumbar kyphotic angle, recovery of neurological function and fusion time were, respectively, compared between Group A and Group B. RESULTS: The average follow-up period for Group A was 46.6 ± 16.7 months, and for Group B, 47.5 ± 15.0 months. It was obvious that the average operative duration and blood loss of Group A was less than those of Group B. Lumbar tuberculosis was completely cured and the grafted bones were fused in 10 months in all patients. There was no persistence or recurrence of infection and no differences in the radiological results in both groups. The kyphosis was significantly corrected after surgical management. The average pretreatment ESR was 60.7 ± 22.5 mm/h, which became normal (9.0 ± 2.8 mm/h) within 3 months in all patients. CONCLUSIONS: Surgical management by one-stage posterior debridement, TLIF and instrumentation for lumbar tuberculosis is feasible and effective. This approach obtained better clinical outcomes than combined posterior and anterior surgeries.

    ABSTRACT: PURPOSE: To evaluate the clinical study efficacy and feasibility of 11 children with tuberculosis of the upper cervical spine treated by one-stage posterior debridement, short-segment fusion, and posterior instrumentation. METHODS: Eleven children who suffered from tuberculosis of the upper cervical spine were admitted to our hospital between June 2005 and December 2010. All of them were treated by one-stage posterior debridement, short-segment fusion, and posterior instrumentation. Then, the clinical efficacy was evaluated using statistical analysis based on the materials about the visual analogue scale (VAS) scores of pain, JOA scores of nerve function and erythrocyte sedimentation rate (ESR), which were collected at certain time. RESULTS: The average follow-up period was 28.1 ± 10.5 months (13-42 months). In the 11 cases, no postoperative complications related to instrumentation occurred and neurologic function was improved in various degrees. The average pretreatment ESR was 58.4 ± 4.9 mm/h (53-69 mm/h), which got normal (8.9 ± 6.5 mm/h) within 3 months in all patients. The average preoperative VAS was 7.4 ± 2.2, which decreased to 1.6 ± 1.8 postoperatively. Mean preoperative JOA was 11.2 ± 3.8, and the JOA at the last visit was 16.3 ± 1.0. All patients got bony fusion within 3-8 months after surgery. CONCLUSIONS: One-stage posterior debridement, short-segment fusion, and posterior instrumentation can be an effective treatment method for the treatment of tuberculosis of the upper cervical spine in children.

    ABSTRACT: PURPOSE: To evaluate the clinical study efficacy and feasibility of 17 aged patients with lumbo-sacral tuberculosis treated by one-stage posterior transforaminal lumbar debridement, interbody fusion, and posterior instrumentation. METHODS: 17 aged patients who suffered from lumbo-sacral tuberculosis were admitted into our hospital between March 2003 and October 2010. All of them were treated by one-stage posterior transforaminal lumbar debridement, interbody fusion, and posterior instrumentation. Then the clinical efficacy with statistical analysis was evaluated based on the materials on the lumbo-sacral angle, neurological status that was recorded by Frankel grade system, and erythrocyte sedimentation rate (ESR), which were collected at certain time. RESULTS: The average follow-up period was 47.5 ± 17.1 months (17-71 months), In the 17 cases, no postoperative complications related to instrumentation occurred and neurologic function was improved in various degrees. The mean preoperative lumbo-sacral angle was 20.5° ± 1.7° (range 18.0°-23.0°). The lumbo-sacral angle became 29.1° ± 1.5° (range 26.4°-31.0°) postoperatively. The average pretreatment ESR was 57.4 ± 16.8 mm/h (33-95 mm/h), which got normal (9.2 ± 3.1 mm/h) within 3 months in all patients. All patients got bony fusion within 6-8 months after surgery. CONCLUSIONS: One-stage posterior transforaminal lumbar debridement, interbody fusion, and posterior instrumentation can be an effective treatment method for the treatment of lumbo-sacral tuberculosis in the aged patients.

    ABSTRACT: Many investigators advocate anterior release combined with halo-femoral traction and posterior fusion when treating stiff thoracic curves in patient with adolescent idiopathic scoliosis (AIS). But the anterior operations often induce severe complications. Some surgeons choose posterior-only surgery with halo-femoral traction, posterior wide release and correction. But to the best of our knowledge, there are only rare prospective studies on these posterior-only surgeries for AIS patients who have a rigid curve more than 80° and flexibility less than 35%. Sixty-four AIS patients were recruited from September 2006 to June 2009. All patients had rigid curves and underwent spinal correction. They were randomly divided into group A (combined anteroposterior surgery) and group B (posterior-only surgery). Images and scoliosis research society-22 questionnaire (SRS-22) scores were performed pre- and post-operation and during follow-up visits. The operation time, blood loss, hospital days, and hospital charges were compared between the two groups. These patients were followed for an average of 37.5 months (range, 24 - 65 months). No serious complications were observed. There were no significant differences between the two groups in gender, age, preoperative radiographic data, or preoperative SRS-22 score. The average operation time, blood loss, hospital days and hospital charges in group B were less than those in group A. The SRS-22 score in group B was better than in group A at post-operation and at final follow-up. In AIS with a rigid curve more than 80° and flexibility less than 35%, strong halo-femoral traction with wide posterior spinal release and three dimensional spinal correction can provide better SRS-22 scores, comparable curve correction, shorter operation time, less blood loss, shorter hospital stays and lower charges when compared to combined anterior and posterior surgery.

    ABSTRACT: Multilevel noncontiguous thoracic spinal tuberculosis has rarely been reported in the literature. We present a retrospective clinical study of 14 patients with multilevel noncontiguous thoracic spinal tuberculosis treated by single-stage posterior transforaminal thoracic debridement, limited decompression, interbody fusion, and posterior instrumentation (modified TTIF) and determine the clinical effectiveness of such surgical treatment for MNTST. Fourteen patients with multilevel noncontiguous thoracic spinal tuberculosis were treated with modified TTIF. The mean follow-up was 27.36 ± 10.46 months (range 13-42 months). The kyphotic angle ranged from -2° to 47° before operation, with an average of 19.21° ± 12.63°. The erythrocyte sedimentation rate (ESR) of patients upon admission ranged from 30 to 62 mm/h before operation, with an average of 46.43 ± 10.77 mm/h. The Frankel Grade was used to evaluate the neurological deficits. The average ESR got normal (8.14 ± 5.89 mm/h) within 3 months in all patients. The average kyphotic angle decreased to 8.07° ± 6.91° postoperatively. Mean deformity angle was measured as 8.79° ± 7.29° at the last visit. Solid fusion was achieved in all cases. Neurologic status of the 12 patients with preoperative neurologic deficit was 6 with grade D recovered to normal; 2 with grade B, both of them to grade D; 4 with grade C, 2 to grade D, 1 to grade E, and 1 still in grade C. Modified TTIF can be an effective treatment method of multilevel noncontiguous thoracic spinal tuberculosis.

    ABSTRACT: Retrospective case series. To study the correction and fusion strategies for adult thoracolumbar or lumbar scoliosis with Chiari malformation and syringomyelia by using posterior pedicle screw instrumentation (PPSI). Surgical intervention for Chiari malformation and syringomyelia before surgical correction of scoliosis has been reported; however, there are no clinical trials for the PPSI-based correction and fusion procedures used in these patients. From 2002 to 2009, 13 adult patients (mean age, 34.9 years) suffering from thoracolumbar or lumbar scoliosis with Chiari malformation and syringomyelia underwent correction and fusion by using PPSI. Preoperative, postoperative, and final follow-up coronary Cobb angle, correction rate, pelvic obliquity (PO), apical vertebral rotation (AVR), apical vertebral translation (AVT), trunk shift (TS), sagittal thoracic kyphosis angle, and lumbar lordosis angle were analyzed on radiographs. The preoperative and postoperative mean coronary Cobb angle was from 46.8° to 9.2°, correction rate was 80.7%, PO from 9.9° to 3.2°, AVR from 1.9° to 0.3°, AVT from 3.6 to 0.8 cm, TS from 16.8 to 1.6 cm, sagittal thoracic kyphosis angle from 18.2° to 23.5°, and lumbar lordosis angle was from 37.4° to 41.8°. The mean follow-up period was 35.2 months (range, 24-50 months). There were no obvious pseudoarticulations or loss of correction and trunk equilibrium at the final follow-up; no aggravation of the original neural symptoms or new irreversible neural injury was observed. In patients with mild or moderate adult thoracolumbar or lumbar scoliosis with Chiari malformation and syringomyelia, the correction and fusion by using PPSI can yield a satisfactory clinical effect.

    ABSTRACT: To determine the efficacy and feasibility of surgical management of cervicothoracic tuberculosis accompanied by kyphosis in children by using one-stage posterior focus debridement, bone graft fusion, and instrumentation at a single institution. Ten consecutive cases with cervicothoracic tuberculosis with kyphosis were treated with one-stage posterior focus debridement, bone graft fusion, and instrumentation. The mean follow-up was 36 months (range 26-47 months). The kyphotic angle ranged from 35° to 62° before operation, 50.5° in average. The American Spinal Injury Association score system was used to evaluate the neurological deficits. Spinal tuberculosis was completely cured in all ten patients. There was no recurrent tuberculous infection. The postoperative kyphotic angle was 10° to 22°, 17.5° in average, and there was no significant loss of the correction at the latest follow-up. Solid fusion was achieved in all cases. Neurological condition in all patients was improved after surgery. One-stage posterior debridement, bone grafting, and instrumentation can be an effective treatment method of cervicothoracic spinal tuberculosis with kyphosis in children.

    ABSTRACT: Studies have shown that the vitamin D receptor (VDR) gene polymorphisms may be associated with pulmonary tuberculosis (TB) and play important roles in the regulation of calcium in a variety of tissues including bone. To our knowledge, however, whether FokI polymorphism in VDR gene is associated with susceptibility to spinal TB is still unknown. We undertook this study to investigate the association between FokI polymorphism in VDR gene and susceptibility to spinal TB in Chinese Han population. This study included 110 patients with spinal TB and 102 volunteers as controls. FokI polymorphism in VDR gene was analyzed by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) in the spinal TB group and the control group. The frequencies of VDR-FokI genotypes in the two groups were compared using chi(2) test. There was a significant difference between groups in regard to the frequencies of the VDR-FokI genotypes (p <0.05). In the spinal TB group, the frequency of the ff genotype was 46.36%, which was significantly higher than the corresponding value for the control group (28.43%). Furthermore, the odds ratio (OR) was 2.176 (p <0.05), and the 95% confidence interval (CI) ranged from 1.236-3.832. FokI polymorphism in VDR gene may be associated with the susceptibility to spinal TB in Chinese Han population. Furthermore, the ff genotype may be the susceptible genotype of spinal TB.

    ABSTRACT: The goal of this study was to determine the efficacy and feasibility of surgical management of advanced thoracolumbar spine tuberculosis with kyphosis in children in poor general condition with 1-stage posterior decompression, interbody grafts, and posterior instrumentation and fusion. Between 2006 and 2008, 7 children with advanced thoracolumbar spinal tuberculosis accompanied by kyphosis and in poor general condition were treated with 1-stage posterior decompression, interbody grafts, and posterior instrumentation and fusion followed by chemotherapy. Mean follow-up was 34 months (range, 27-42 months). Patients were evaluated pre- and postoperatively for erythrocyte sedimentation rate (ESR), neurological status, pain, spinal canal compromise, and kyphotic angle. Spinal tuberculosis was completely cured and the grafted bones fused in all 7 patients. There was no recurrence of the disease in any patient at final follow-up. In all patients, ESR was normal within 3 months, Frankel neurological classification improved, and pain relief was obtained. Average canal compromise was 52.57% (range, 35%-75%) preoperatively and 9.86% (range, 0%-19%) postoperatively. Average preoperative kyphosis was 37.9°, which decreased to 5.4° postoperatively. There was no significant loss of correction at last follow-up. Our results show that 1-stage posterior decompression, interbody grafts, and posterior instrumentation and fusion followed by chemotherapy is an alternative treatment for children with advanced thoracolumbar spinal tuberculosis and in poor general condition.

    ABSTRACT: To evaluate the influence of perioperative nutritional support on nutritional status of patients with thoracolumbar spinal tuberculosis. Forty-eight patients with thoracolumbar spinal tuberculosis (male 25 and female 23, aged from 35 to 60 years, with an average of 48.25 years) were randomized into two groups. Twenty-four patients nutritional support were increased intravenously for 14 days (7 days before and after operation) in experimental group. Twenty-four patients in control group were supplied with routine diet. The body weight, plasma concentrations of albumin and ESR were detected on the 7th day before operation and on the 7th day after operation. The total wound drainage was recorded and compared. Body weight and plasma concentrations of albumin on the 7th day after operation and those on the 7th day before operation were not significantly different in experimental group (P > 0.05). In control group, body weight and plasma concentrations of albumin on the 7th day after operation was lower than those on the 7th day before operation (P < 0.05). The total wound drainage of experimental group was less than that of control group (P < 0.05). ESR on the 7th day after operation was lower than that on the 7th day before operation in two groups (P < 0.05); but the decrease of ESR in experimental group was more than that in control group (P < 0.05). Nutritional support is beneficial to alleviating innutrition caused by tubercle bacillus and operation. It can promote the effects of operation and anti-tuberculotic drugs.

    ABSTRACT: To investigate the effect of interventional therapy in the treatment of intervertebral space infection. The needle was punctured into the infected intervertebral space from the post-lateral side of the spine monitored by X-rays. The pus was drained, the degenerative disc tissues and necrosis tissues were excised and taken out, and at the end a drainaging catheter was put into the space through the needle. The patient should lie in bed absolutely. The antibiotics was injected into the space through the silicon catheter every day. Three to four weeks later, the catheter was removed. All the 8 patients got good results after the therapy. The low back pain was dramatically alleviated instantly at the day of operation. Erythrocyte sedimental rate gradually descended. After 3 approximately 4 weeks of treatment,the catheter was removed. Interventional therapy of the intervertebral space infection has notable advantage over the open operation.
