The objective of this study was to investigate the treatment and prognosis of patients with spinal tuberculosis in Guizhou province. A total of 863 patients with spinal tuberculosis admitted to our hospital from 2006 to 2017 were included in this study. All patients underwent standardized quadruple antituberculosis treatment. Eighty patients were lost to follow-up due to a change of their contact information or noncompliance. A total of 783 patients completed the follow-up. The average follow-up period was 20.33 ± 8.77 months (range: 6 to 38 months). Among these patients, 145 patients underwent conservative treatment, while 638 patients underwent surgical treatment. All patients in the surgery group were treated with lesion removal, bone graft fusion, and internal fixation. Preoperative and postoperative standard quadruple antituberculosis treatment was administered. The clinical efficacy was evaluated according to erythrocyte sedimentation rate (ESR), c-reactive protein (CRP), visual analogue scale (VAS), Cobb angle correction, neurological functional recovery, and interbody fusion with bone graft and tuberculosis outcome. A total of 608 patients achieved clinical cure. The symptoms, physical signs, blood tests and imaging findings were improved in 143 patients. Twenty patients showed refractory clinical symptoms, and 12 patients had local tuberculosis recurrence. Conservative and surgical treatments are the mainstream treatments for spinal tuberculosis. According to the patients’ individual conditions, individualized treatments should be used to achieve good efficacy. Standardized antituberculosis treatment should be applied over the course of spinal tuberculosis. [ABSTRACT FROM AUTHOR]

Objective is to describe a safe and effective percutaneous endoscopic approach for removal of highly migrated and sequestrated disc herniations of the upper lumbar spine and to report the results, surgical indications, and technical considerations of the new technique. Eleven patients who had highly migrated and sequestrated disc herniations in the upper lumbar were included in this study. A retrospective study was performed for all patients after translaminar osseous channel-assisted PELD was performed. Radiologic findings were investigated, and pre-and postoperative visual analog scale (VAS) assessments for back and leg pain and Oswestry disability index (ODI) evaluations were performed. Surgical outcomes were evaluated under modified MacNab criteria. All of the patients were followed for more than 1 year. The preoperative and postoperative radiologic findings revealed that the decompression of the herniated nucleus pulposus (HNP) was complete. After surgery, the mean VAS scores for back and leg pain immediately improved from 8.64 (range, 7–10) and 8.00 (range, 6–10) to 2.91 (range, 2–4) and 2.27 (range, 1–3), respectively. The mean preoperative ODI was 65.58 (range, 52.2–86), which decreased to 7.51 (range, 1.8–18) at the 12-month postoperative follow-up. The MacNab scores at the final follow-up included nine excellent, one good, and one fair. The modified translaminar osseous channel-assisted PELD could be a safe and effective option for the treatment of highly migrated and sequestrated disc herniations of the upper lumbar.

Objective is to analyze the surgical strategy, safety, and clinical results of percutaneous full-endoscopic discectomy through interlaminar or extraforaminal puncture technique for LDH. Preoperative CT and MRI were analyzed, which were based on the main location of the herniated disc and its relationship with compressed nerve root. Sixty-two patients satisfied the inclusion criteria during the period from August 2012 to March 2014. We use percutaneous full-endoscopic discectomy through different puncture technique to remove the protrusive NP for LDH. Sixty patients completed the full-endoscopic operation successfully. Their removed disc tissue volume ranged from 1.5 mL to 3.8 mL each time. Postoperative ODI and VAS of low back and sciatica pain were significantly decreased in each time point compared to preoperative ones. No nerve root injury, infection, and other complications occurred. The other two patients were shifted to open surgery. No secondary surgery was required and 91.6% of excellent-to-good ratio was achieved on the basis of Macnab criteria at postoperative 12 months. Acquired benefits are fewer complications, rapid recovery, complete NP removal, effective nerve root decompression, and satisfactory cosmetic effect as well. This is a safe, effective, and rational minimally invasive spine-surgical technology with excellent clinical outcome. [ABSTRACT FROM AUTHOR]

Objective: ?To evaluate the feasibility and effectiveness of one-stage posterior retaining part facet joint in laminectomy, bone graft and debridement combined with short segmental pedicle screw fixation for lumbosacral spinal tuberculosis., Methods: ?Between January 2010 and December 2014, 32 cases of lumbosacral spinal tuberculosis (L 4 -S 1 ) were treated by one-stage posterior retaining part facet joint in laminectomy, bone graft and debridement combined with short segmental pedicle screw fixation. There were 20 males and 12 females, aged 17-62 years (mean, 43 years). The disease duration was 12-48 months (mean, 18 months). The involved segments included L 5 , S 1 level in 19 cases and L 4, 5 level in 13 cases. The effectiveness was evaluated by Oswestry disability index (ODI) and imaging parameters (lumbar-sacral angle correction and Bridwell classification and CT fusion criteria) after operation., Results: ?The operation was successfully completed in all patients; the average operation time was 180 minutes, and the average intraoperative blood loss was 400 mL. All cases were followed up 12 to 67 months (mean, 15.6 months). At last follow-up, common toxic symptom of tuberculosis disappeared, and no internal fixation failure occurred. Neurological function was recovered to normal in 7 patients with neurological symptoms, and American Spinal Injury Association (ASIA) scale was improved to grade E from grade C (2 cases) and grade D (5 cases) before operation. At 1 year and last follow-up, the ODI scores were significantly improved when compared with preoperative score (P<0.05), but no significant difference was found between at 1 year and last follow-up (P>0.05). The lumbarsacral angle was significantly increased at 7 days, 1 year and last follow-up when compared with preoperative one (P<0.05), but there was no significant difference between different time points after operation (P>0.05). The bone graft fusion time was 9-24 months (mean, 12 months). At 1 year after operation and last follow-up, X-ray Bridwill bone fusion rates were 87.50% (28/32) and 93.75% (30/32) respectively, and CT fusion rates were 87.50% (28/32) and 90.63% (29/32) respectively; and there was significant difference in interbody fusion between at 1 year and last follow-up (P<0.05). Drug resistance was observed in 4 cases; Bridwill grade Ⅲ and grade Ⅳ fusion was shown in 3 cases and 1 case after adjusting the anti-tuberculosis scheme after 1 year., Conclusions: ?One-stage posterior retaining part facet joint in laminectomy and debridement can effectively clear the tuberculose focus, intervertebral bone graft combined with short segment pedicle screw fixation can maintain postoperative spinal reliable stability and get satisfactory bone fusion rate, so it is an effective method for the treatment of lumbosacral tuberculosis.

Objective: To study the effectiveness of posterior laminotomy decompression and bone grafting via the injured vertebrae for treatment of thoracolumbar burst fractures., Methods: Between November 2010 and November 2012, 58 patients with thoracolumbar burst fractures were treated by posterior fixation combined with posterior laminotomy decompression and intervertebral bone graft in the injured vertebrae. There were 40 males and 18 females with a mean age of 48 years (range, 25-58 years). According to Denis classification, 58 cases had burst fractures (Denis type B); based on neurological classification of spinal cord injury by American Spinal Injury Association (ASIA) classifications, 5 cases were rated as grade A, 18 cases as grade B, 20 cases as grade C, 14 cases as grade D, and 1 case as grade E. Based on thoracolumbar burst fractures CT classifications there were 5 cases of type A, 20 cases of type B1, 10 cases of type B2, and 23 cases of type C. The time between injury and operation was 10 hours to 9 days (mean, 7.2 days). The CT was taken to measure the space occupying of vertebral canal. The X-ray film was taken to measure the relative height of fractured vertebrae for evaluating the vertebral height restoration, Cobb angle for evaluating the correction of kyphosis, and ASIA classification was conducted to evaluate the function recovery of the spinal cord., Results: The operations were performed successfully, and incisions healed primarily. All the patients were followed up 12-18 months (mean, 15 months). CT showed good bone graft healing except partial absorption of vertebral body grafted bone; no loosening or breakage of screws and rods occurred. The stenosis rates of fractured vertebral canale were 47.56% ± 14.61% at preoperation and 1.26% ± 0.62% at 1 year after operation, showing significant difference (t = 24.46, P = 0.00). The Cobb angles were (16.98 ± 3.67)° at preoperation, (3.42 ± 1.45)° at 1 week after operation, (3.82 ± 1.60)° at 1 year after operation, and (4.84 ± 1.70)° at 3 months after removal of internal fixation, showing significant differences between at pre- and post-operation (P < 0.05). The relative heights of fractured vertebrae were 57.10% ± 6.52% at preoperation, 96.26% ± 1.94% at 1 week after operation, 96.11% ± 1.97% at 1 year after operation, and 96.03% ± 1.96% at 3 months after removal of internal fixation, showing significant differences between at pre- and post-operation (P < 0.05). At 1 year after operation, the neural function was improved 1-3 grades in 56 cases. Based on ASIA classifications, 1 case was rated as grade A, 4 cases as grade B, 10 cases as grade C, 23 cases as grade D, and 20 cases as grade E., Conclusion: Treatment of thoracic and lumbar vertebrae burst fractures by posterior laminotomy decompression and bone grafting via the injured vertebrae has satisfactory effectiveness, which can reconstruct vertebral body shape and height with spinal cord decompression and good vertebral healing. It is a kind of effective solution for thoracolumbar burst fracture.
