Objective To explore the injury mechanism, clinical features and treatment methods of multiple-level noncontiguous spinal fractures(MNSF). Methods The clinical data of 23 patients with MNSF were analyzed retrospectively. Therewere 15 males and 8 females aging from 13 to 75 years. Five cases missed diagnosis. The locations of the primary injury were cervical region in 3 cases, thoracic region in 7 cases, and thoracolumbar region in 13 cases. The spinal fractures associated with spinal cord injury were 14 cases in the primary injury, and 3 cases in the secondary injury. According to Frankel grade, there were 7 cases ofgrade A, 1 case of grade B, 3 cases of grade C, 6 cases of grade D and 6 cases of grade E. Sixteen cases were treated by surgical stabilization while 7 cases were treated conservatively. Results Twenty patients were followed up from 3 months to 4 years with a mean of 11.5 months except three patients. No neurologic deterioration was observed in patients who were treated conservatively or operatively. No wound infection, no implant failure or bone graft nonunion occurred in patients who were treated operatively. Among 17 patients with neurologic deficit before operation, 12 got 1-3 grade improvement of the Frankel grading, 4 remained unchanged and 1 died. Conclusion The mechanism of MNSF injury is complex, it is easy to miss diagnosis. The patients with spinal injury must be examined carefully and completely. A whole spine radiographic survey should be accomplished if necessary and treatments should be based on the stability of spine fractures and the severity of spinal cord injury.
Objective To assess the outcomes of pedicle subtration osteotomy and short-segment pedicle screw internal fixation in kyphosisdeformity. Methods From June 2001 to November 2003, 16 cases of kyphosis deformity were treated with pedicle subtration osteotomy and short-segment pedicle screw internal fixation, including 11 males and 5 females and aging 24-51 years. The kyphosis deformity was caused by ankylosing spondylitis in 12 cases, old lumbothoracic fracturedislocation in 2 cases, and vertebral dysplasia in 2 cases. The disease course was 7-25 years with an average of 12.8years. The whole spine radiographs were taken pre-and postoperatively. The sagittal balance was assessed by measuring thoracic kyphosis angle, lumbar lordosis angle, acrohorizontal angle and distance between posterosuperior point of S1and the vertical line. The clinical outcomes were assessed by Bridwell-Dewald scale for spinal disorders. Results The mean follow-up period was25.6 months. The mean bleeding was 1 100 ml. Satisfactory bone graft healing was achieved at final follow-up. Complications were paralytic intestinal obstruction in 1 case, dura laceration in 1 case, and temporary lower limb paralysis in 2 cases. Final follow-up radiograph showed an increase in lumbar lordosis angle from 9.6±16.4° to 42.6±14.3°(P＜0.05), whereas thoracic kyphosis angle remained relative stable. The distance between posterosuperior point of S1 and the vertical line was decreased from 97.5±45.6 mm to 10.7±9.6 mm(P＜0.05). Satisfactory clinical outcome was achieved by evaluating the changes of pain, social and working status. Conclusion Pedicle subtraction osteotomy and short-segment pedicle screw internal fixation is effective for correction of kyphosis deformity.
Objective To explore the feasibilities, methods, outcomes and indications of atlas pedicle screw system fixation and fusion for the treatment of upper cervical diseases. Methods From October 2004 to January 2006, 17 patients with upper cervical diseases were treated with atlas pedicle screw system fixation and fusion. There were 13 males and 4 females, ageing 19 to 52 years. Of 17 cases, there were 14 cases of atlantoaxial dislocation(including 3 cases of congenital odontoid disconnection，4 cases of old odontoid fracture，2 cases of new odontoid fracture(typeⅡC), 3 cases of rupture of the transverse ligament, and 2 cases of atlas fracture； 2 cases of tumor of C2; 1case of giant neurilemoma of C2,3 with instability after the resection oftumors. JOA score before operation was 8.3±3.0. Results The mean operative time and bleeding amount were 2.7 hours (2.1-3.4 hours) and 490 ml (300-750 ml) respectively. No injuries to the vertebral artery and spinal cord were observed. The medial-superior cortex of lateral mass was penetrated by 1 C1 screw approximately 3 mmwithout affecting occipito-atlantal motions. All patients were followed up 3-18 months. The clinical symptoms were improved in some extents and the screws were verified to be in a proper position, no breakage or loosening of screw and rob occurred. All patients achieved a solid bone fusion after 3-6 months. JOA score 3 months after operation was14.6±2.2. JOA improvement rates were 73%-91%(mean 82%). Conclusion The atlas pedicle screw system fixation and fusion is feasible for the treatment of upper cervical diseases and has betteroutcomes, wider indications if conducted properly.

OBJECTIVE: To investigate the operative indications and techniques of the universal spine system (USS) in reconstruction of the stability of the lumbar-sacrum joint after resection of sacrum tumor. METHODS: Nine patients were treated with USS after resection of sacrum tumor. Among them, there were 6 males and 3 females, aged from 34-60 years. The operation could be divided into four main procedures: 1. to resect sacrum tumor; 2. to insert the pedicle screw into the normal pedicle (L3 or L4 or L5) above the region of laminectomy; 3. to insert the lower screw into the iliac plate; 4. to put the rods, bone graft and links. RESULTS: There was no recurrence of sacrum tumor by MRI examination during 7-17 month follow-up. The pains of the lumbar-sacrum joint and the spinal nerve root were relieved obviously. The patients could stand and walked normally. There was no loose screw and no fracture of the screw and the rod. There was no appearance of the enlarged screw passage, the lessened pelvis and lowed L5 spine. CONCLUSION: Reconstruction of the lumbar-sacrum joint by the USS after resection of sacrum tumor is a practical operation clinically. It is characterized by the easy manipulation, few complication and stable fixation.
Objective To analyze the technical notes, effectiveness, and current issues of real-time three-dimensional CT navigation-guided full-endoscopic lumbar interbody fusion. Methods Between April 2020 and October 2021, a total of 27 patients received real-time three-dimensional CT navigation-guided full-endoscopic lumbar interbody fusion. There were 18 males and 9 females with an average age of 63.2 years (range, 48-84 years). There were 6 cases of lumbar spinal stenosis, 1 case of lumbar instability, 9 cases of lumbar spinal stenosis with instability, 3 cases of degenerative spondylolisthesis, 6 cases of isthmus spondylolisthesis, and 2 cases of recurrent lumbar disc herniation. All patients showed neurological symptoms before operation (ipsilateral symptom for 15 cases and bilateral symptom for 12 cases). The symptom duration was 1-300 months (median, 24 months). The operations were performed via transforaminal approach in 8 cases, trans-facet joint approach in 18 cases, and combined approaches in 1 case. A total of 32 levels were fused, including 23 single-level cases, 3 two-level cases, and 1 three-level case. Lumbar fusion segment was L2, 3 in 1 case, L3, 4 in 4 cases, L4, 5 in 20 cases, and L5, S1 in 7 cases. The operation time, intraoperative estimated blood loss (IEBL), and perioperative complications were recorded. The improvement of intervertebral space height at fusion level was measured, and the accuracy of percutaneous pedicle screw (PPS) and Cage placement was also evaluated based on CT images performed at 1 week postoperatively. Visual analogue scale (VAS) score for both low back pain and leg pain, Japanese Orthopaedic Association (JOA) score, and Oswestry disability index (ODI) were evaluated before operation, at 1 week postoperatively, and at last follow-up. Satisfaction to effectivenss were assessed by patients using modified MacNab criteria at last follow-up. Results The operation time was ranged from 255 to 805 minutes (mean, 424.9 minutes). IEBL was 150-290 mL (mean, 219.3 mL). All patients received follow-up with the duration from 4 to 22 months (mean, 12.4 months). At 1 week postoperatively and last follow-up, VAS scores of low back pain and leg pain, JOA score, and ODI were significantly improved when compared with those before operation (P<0.05). At last follow-up, the clinical indicators were similar in comparison with those at 1 week postoperatively (P>0.05). There were 26 patients and 1 patient who respectively ranked excellent and mild in terms of effectiveness according to the modified MacNab criteria, with the excellent and good rate of 96.3%. There was 1 patient who suffered from incomplete injury of L5 nerve root and partial neurological function recovered after 3-month conservative treatments. There were 118 implanted PPSs, and 116 of them were implanted under navigation. There were 33 Cages that were implanted under navigation. The accuracy of PPS and Cage placement was 99.1% and 97.0% respectively based on CT performed at 1 week postoperatively. The postoperative intervertebral space height was significantly increased in comparison with that before operation (P<0.05). During follow-up, mild Cage subsidence was observed in 1 patient, whereas no fixation loosing was found. Conclusion Real-time three-dimensional CT navigation-guided full-endoscopic lumbar interbody fusion has great safety and effectiveness with satisfactory preliminary clinical results. Design and further improvement of surgical equipment and instruments are expected to resolve the current technical difficulties.
ObjectiveTo evaluate the relationship between tumor necrosis factor-α (TNF-α) gene promoter-308 G/A polymorphism and ankylosing spondylitis (AS) in Chinese population by meta-analysis. MethodsThe casecontrol studies about the correlation between TNF-α gene polymorphism and AS in Chinese population were retrieved from PubMed, EMbase, CNKI, CBM, WanFang Data and VIP database by two researchers. The retrieval time was from their establishment to December, 2015. After the paper screening, data extraction, and assessment of bias risk, the metaanalysis was conducted by Stata 12.0 software. ResultsA total of 11 case-control studies involving 1 154 AS patients and 1 458 controls were included. The results of meta-analysis showed that, for Chinese population, there was no significant association between TNF-α-308 G/A polymorphism and AS susceptibility (A vs. G: OR=0.96, 95% CI 0.63 to 1.47, P=0.86; AA vs. AG: OR=0.97, 95% CI 0.51 to 1.84, P=0.93; AA vs. GG: OR=0.92, 95% CI 0.32 to 2.61, P=0.87; AA+AG vs. GG; OR=1.04, 95% CI 0.60 to 1.80, P=0.89; AA vs. AG+GG: OR=1.03, 95% CI 0.58 to 1.82, P=0.92). ConclusionTo date, it has not found the relationship between TNF-α gene promoter-308 G/A polymorphism and AS in Chinese population. For the quantity and quality limitation of the included studies, the conclusion has to be verified by more large-scale highquality studies.
