RESUMO

OBJECTIVE: To investigate the mechanism of cytosolic phospholipase A2(cPLA2) inhibitor to improve neurological function after spinal cord injury (SCI). METHODS: Thirty-six 3 months old female SD rats, with body mass (280±20) g, were divided into three groups (n=12):sham group, SCI group, and SCI+ arachidonyl trifluoromethyl ketone(AACOCF3) group. Balloon compression SCI model was established in all three groups. In the sham model group, the spinal cord compression model was created after the balloon was placed without pressure treatment, and the remaining two groups were pressurized with the balloon for 48 h. After successful modeling, rats in the SCI+AACOCF3 group were injected intraperitoneally with AACOCF3, a specific inhibitor of cPLA2. The remaining two groups of rats were injected intraperitoneally with saline. The animals were sacrificed in batches on 7 and 14 days after modeling, respectively. And the damaged spinal cord tissues were sampled for pathomorphological observation, to detect the expression of cPLA2 and various autophagic fluxPrelated molecules and test the recovery of motor function. RESULTS: Spinal cord histomorphometry examination showed that the spinal cord tissue in the sham group was structurally intact, with normal numbers and morphology of neurons and glial cells. In the SCI group, spinal cord tissue fractures with large and prominent spinal cord cavities were seen. In the SCI+AACOCF3 group, the spinal cord tissue was more intact than in the SCI group, with more fused spinal cord cavities, more surviving neurons, and less glial cell hyperplasia. Western blot showed that the sham group had the lowest protein expression of LC3-Ⅱ, Beclin 1, p62, and cPLA2 compared with the SCI and SCI+AACOCF3 groups (P<0.05) and the highest protein expression of LC3-Ⅰ (P<0.05). P62 and cPLA2 expression in the SCI group were higher than in the SCI+AACOCF3 group (P<0.05). Behavioral observations showed that the time corresponding to BBB exercise scores was significantly lower in both the SCI and SCI+AACOCF3 groups than in the sham group (P<0.05). Scores at 3, 7, and 14 days after pressurization were higher in the SCI+AACOCF3 group than in the SCI group (P<0.05). CONCLUSION: cPLA2 inhibitors can reduce neuronal damage secondary to SCI, promote neurological recovery and improve motor function by improving lysosomal membrane permeability and regulating autophagic flux.

RESUMO

Background: Peripheral nerve injury (PNI) has devastating consequences. Dorsal root ganglion as a pivotal locus participates in the process of neuropathic pain and nerve regeneration. In recent years, gene sequencing technology has seen rapid rise in the biomedicine field. So, we attempt to gain insight into in the mechanism of neuropathic pain and nerve regeneration in the transcriptional level and to explore novel genes through bioinformatics analysis. Methods: The gene expression profiles of GSE96051 were downloaded from GEO database. The gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes pathway (KEGG) enrichment analyses were performed, and protein-protein interaction (PPI) network of the differentially expressed genes (DEGs) was constructed by Cytoscape software. Results: Our results showed that both IL-6 and Jun genes and the signaling pathway of MAPK, apoptosis, P53 present their vital modulatory role in nerve regeneration and neuropathic pain. Noteworthy, 13 hub genes associated with neuropathic pain and nerve regeneration, including Ccl12, Ppp1r15a, Cdkn1a, Atf3, Nts, Dusp1, Ccl7, Csf, Gadd45a, Serpine1, Timp1 were rarely reported in PubMed database, these genes may provide us the new orientation in experimental research and clinical study. Conclusions: Our results may provide more deep insight into the mechanism and a promising therapeutic target. The next step is to put our emphasis on an experiment level and to verify the novel genes from 13 hub genes.

RESUMO

OBJECTIVE: To explore the therapeutic efficacy of manual reduction combined with percutaneous vertebroplasty in treating osteoporotic vertebral compression fractures(OVCFs) with intravertebral clefts. METHODS: The clinical data of 94 patients with osteoporotic vertebral compression fractures with intravertebral clefts treated from January 2014 to January 2017 were retrospectively analyzed. The patients were divided into group A and group B according to different operative methods. In group A, 45 patients were treated with unilateral approach PVP, including 17 males and 28 females, aged (75.35±11.82) years old, with a bone density T-value of (-4.28±0.65) g/cm³; in group B, 49 patients treated with manual reduction combined with unilateral approach PVP, including 19 males and 30 females, aged (76.79±9.64) years old, with a bone density T-value of (-4.33±0.72) g/cm³. The operation time, bone cement injection volume and postoperative complications of two groups were recorded. The VAS and ODI scores of two groups were analyzed respectively at 1, 12, 18 months after operation. Vertebral height and kyphosis Cobb angle of two groups were compared immediately after surgery and 12, 18 months after operation. The distribution of bone cement in the vertebral body was observed and its distribution excellent rate was calculated. RESULTS: There was no significant difference in operation time between two groups. The amount of bone cement injection was(8.42±1.24) ml in group A and(9.19±1.09) ml in group B, and the difference between two groups was statistically significant(P<0.05). No spinal nerve root injury during operation and no complications including pulmonary embolism, bone cement toxicity and infection were found in two groups. There were 5 cases of bone cement leakage in group A and 4 cases in group B, which did not cause corresponding clinical symptoms and were not treated additionally. The distribution of bone cement in group A was excellent in 25 cases, good in 19 cases, poor in 1 case and in group B was excellent in 45 cases, good in 4 cases. The distribution excellent rate of bone cement was higher in group B than in group A (P<0.05). The VAS and ODI scores before operation and 1, 12, 18 months after operation were 8.29±0.74, 2.59±0.14, 3.75±0.38, 3.84±0.88 and 40.04±3.16, 9.24±2.82, 12.27±2.64, 15.83±2.58 in group A, 8.22±0.82, 2.54±0.19, 2.81±0.23, 2.82±0.45 and 39.98±2.05, 9.16±2.10, 9.46±2.41, 9.76±2.46 in group B. There was no significant difference in VAS and ODI scores at 1 month after operation between two groups (P>0.05), but group A was higher than group B at 12 and 18 months after operation (P<0.05). The vertebral height and Cobb angle before surgery, immediately after surgery, and 12, 18 months after surgery in group A were(59.17±1.42)%, (85.95±2.19)%, (75.27±3.45)%, (68.34±2.24)% and(23.83±3.37)°, (15.26±2.61)°, (17.63±2.16)°, (19.46±2.54)°, and in group B were(59.31±1.87)%, (89.19±2.53)%, (88.62±2.51)%, (88.59±2.62)% and(24.72±3.78)°, (14.91±2.28)°, (15.48±2.55)°, (15.86±2.81)°. Vertebral height Immediately after surgery was greater in group B than in group A and Cobb angle in group B was smaller than in group A (P<0.05). During follow-up, there was no significant change in vertebral height in group B, while vertebral body recollapse in group A(P<0.05). CONCLUSIONS: In the treatment of osteoporotic vertebral compression fractures with intravertebral clefts, the manual reduction combined with PVP is more effective than single PVP, which can effectively prevent vertebral body recollapse and improve the long-term efficacy of patients.

RESUMO

OBJECTIVE: To explore and compare the safety depths of perpendicular and oblique acupuncture at Yamen (GV 15) in patients with atlantoaxial dislocation (AAD) and healthy volunteers. METHODS: One bundred and seventy-seven patients with atlantoaxial dislocation were selected as an AAD group, and 207 patients without atlantoaxial dislocation and with normal anatomical structure were selected as a normal group. All participants were moderately sized. The MRI scanning of the cervical vertebra was performed, and the safety depth of perpendicular and oblique acupuncture at Yamen (GV 15) was calculated on the sagittal image. RESULTS: In the AAD group, the safety depth of men was (45.33±5.17) mm for perpendicular acupuncture and (48.58±4.41) mm for oblique acupuncture; the safety depth of women was (44.17±7.80) mm for perpendicular acupuncture and (47.49±7.32) mm for oblique acupuncture. In the normal group, the safety depth of men was (47.72±5.06) mm for perpendicular acupuncture and (42.69±5.53) mm for oblique acupuncture; the safety depth of women was (44.63±5.85) mm for perpendicular acupuncture and (39.88±6.18) mm for oblique acupuncture. The safety depth of men and women for oblique acupuncture was longer than that for perpendicular acupuncture in the AAD group (P<0.01); the safety depth of men and women for oblique acupuncture was shorter than that for perpendicular acupuncture in the normal group (P<0.01). The safety depth of perpendicular and oblique acupuncture between men and women was not significant in the AAD group (P>0.05); the safety depth of perpendicular and oblique acupuncture for men was longer than that for women in the normal group (P<0.01). For men, the safety depth of perpendicular acupuncture in the AAD group was shorter than that in the normal group (P<0.01), while the safety depth of oblique acupuncture in the AAD group was longer than that in the normal group (P<0.01). For women, the safety depth of perpendicular acupuncture in the AAD group was similar with that in the normal group (P>0.05), while the safety depth of oblique acupuncture in the AAD group was longer than that in the normal group (P<0.01). CONCLUSION: The safe depth of acupuncture at Yamen (GV 15) has significantly changed under AAD, so during the clinical acupuncture the needle insertion should be less than its safe depth.

RESUMO

Decompression is the major therapeutic strategy for acute spinal cord injury, but there is some debate about the time window for decompression following spinal cord injury. An important goal and challenge in the treatment of spinal cord injury is inhibiting or reversing secondary injury. Governor Vessel electroacupuncture can improve symptoms of spinal cord injury by inhibiting cell apoptosis and improving the microenvironment of the injured spinal cord. In this study, Governor Vessel electroacupuncture combined with decompression at different time points was used to treat acute spinal cord injury. The rat models were established by inserting a balloon catheter into the atlanto-occipital space. The upper cervical spinal cord was compressed for 12 or 48 hours prior to decompression. Electroacupuncture was conducted at the acupoints Dazhui (GV14) and Baihui (GV 20) (2 Hz, 15 minutes) once a day for 14 consecutive days. Compared with decompression alone, hind limb motor function recovery was superior after decompression for 12 and 48 hours combined with electroacupuncture. However, the recovery of motor function was not significantly different at 14 days after treatment in rats receiving decompression for 12 hours. Platelet-activating factor levels and caspase-9 protein expression were significantly reduced in rats receiving electroacupuncture compared with decompression alone. These findings indicate that compared with decompression alone, Governor Vessel electroacupuncture combined with delayed decompression (48 hours) is more effective in the treatment of upper cervical spinal cord injury. Governor Vessel electroacupuncture combined with early decompression (12 hours) can accelerate the recovery of nerve movement in rats with upper cervical spinal cord injury. Nevertheless, further studies are necessary to confirm whether it is possible to obtain additional benefit compared with early decompression alone.

RESUMO

OBJECTIVE: To explore the clinical efficacy of unilateral open-door laminoplasty combined with foraminotomy for cervical ossification of posterior longitudinal ligament(OPLL). METHODS: The clinical data of 45 patients with OPLL underwent surgical treatment between September 2011 and September 2015 were retrospectively analyzed. There were 26 males and 19 females with a mean age of 53.6 years old(ranged from 28 to 71 years). Among them, 24 cases received the surgery of unilateral open-door cervical laminoplasty combined with foraminotomy(combined group), and 21 cases received a single unilateral open-door cervical laminoplasty(single group). Operation time, intraoperative blood loss, complications including C5 nerve root palsy and axial symptoms were compared between two groups. Pre-and post-operative Japanese Orthopedic Association(JOA) score, improvement rate of neurological function, Neck Disability Index(NDI) score, and cervical Cobb angle were recorded and analyzed between the two groups. RESULTS: All the patients were followed up for 12-24 months, with an average of (14.3±2.8) months for combined groups and (13.7±3.1) months for single group, and no significant difference was found between the two groups(P>0.05). There was no significant difference in operation time and intraoperative blood loss between two groups(P>0.05). Postoperative JOA scores obtained obvious improvement in all patients(P<0.05). However, there was no significant difference between two groups for the improvement rate of neurological function(P>0.05). At final follow-up, NDI scores of combined group and single group were 13.6±1.8 and 16.1±2.4 respectively, there was significant difference between two groups(P<0.05). The incidence of C5 nerve root palsy was lower in combined group(4.2%) than that of single group (28.6%). There was no significant difference in incidence rate of axial symptoms between two groups(P>0.05). There was no significant difference in cervical Cobb angle between pre-and post-operative conditions, or between two groups(P>0.05). CONCLUSIONS: Unilateral open-door cervical laminoplasty combined with foraminotomy is an effective method to treat cervical OPLL, which could provide sufficient decompression of spinal cord and nerve root, prevent the C5 nerve root palsy.

RESUMO

BACKGROUND: In the current surgical therapeutic regimen for symptomatic cervical degenerative disc disease, both anterior cervical discectomy and fusion (ACDF) and anterior cervical disc replacement (ACDR) are still widely accepted. However, many complications exist in both surgeries. Therefore, this study aims to compare the adverse events between ACDR and ACDF, and provide vital evidence-based guidance for spine surgeons and designers to evaluation of prognosis and improvement of dynamic devices. METHODS: A systematic review and meta-analysis that will be performed according to the PRISMA. The electric database of PubMed, Medline, Embase, Google Scholar, and Cochrane library will be systematic search. A standard data form will be used to extract the data of included studies. We will assess the studies according to the Cochrane Handbook for Systematic Reviews of Interventions, and perform analysis in RevMan 5.3 software. Fixed effects models will be used for homogeneity data, while random-effects will be used for heterogeneity data. The overall effect sizes will be determined as weighted mean difference (WMD) for continuous outcomes and relative risk (RR) for dichotomous outcomes. RESULT: The results of this study will be disseminated via international or national conferences, or submit to peer-reviewed journal in spinal field. CONCLUSION: The conclusion of this study will provide key evidence-based guidance for spine surgeons and designers to the evaluation of prognosis and improvement of dynamic devices.

RESUMO

OBJECTIVE: To investigate the effect and mechanism of Buyanghuanwu decoction on platelet activating factor expression in spinal cord tissue of model of acute upper cervical spinal cord injury in rats. METHODS: Sixty SPF grade 3-month-old female Wistar rats were randomly divided into sham operation group, model group, methylprednisolone group and Buyanghuanwu decoction (Traditional Chinese Medicine group, TCM), with 15 rats in each group. The first day after the modeling, the methylprednisolone group were treated by injection of the tail vein for a total of 24 h, the first dose of 30 mg/kg, followed by a dose of 5.4 mg/kg·h, and 1 time per 4 h. The traditional Chinese medicine group was prepared with a medium dose of Buyanghuanwu decoction granules which were prepared into a solution containing 2 g/ml of granules, 3.5 g/kg per day gavage, was equivalent to 1 time the amount of adult consumption. The model group and the sham operation group were given equal volume of normal saline for 2 times a day for 2 weeks. The recovery of nerve function was evaluated by BBB classification at 1, 3, 7, 14 days after treatment. The expression of PAF in the segment of spinal cord injury was detected by double antibody sandwich (ELISA) method at 1, 7, and 14 d postoperatively. RESULTS: At the first day after treatment, BBB score in model, TCM and methylprednisolone groups were lower than that of sham operation group(P<0.01), but there was no difference among the three groups(P>0.05). At 7, 14 days afer treatment, BBB score in TCM and methylprednisolone groups were higher than that of model group significantly(P<0.01); but there were no significant difference between TCM group and methylprednisolone group(P>0.05). PAF expression in TCM group and methylprednisolone group were lower than that of model group at 7, 14 day afer treatment significantly (P<0.05); but there were no significant difference between TCM group and methylprednisolone group (P>0.05). CONCLUSIONS: Buyanghuanwu decoction treatment after acute upper cervical spinal cord injury can significantly improve locomotor recovery by inhibiting the expression of PAF.

RESUMO

OBJECTIVE: To compare the clinical effect between spinal card decompression combined with traditional Chinese medicine and simple spinal card decompression for cervical spondylotic myelopathy. METHODS: From June 2012 to June 2015, 73 patients with cervical spondylotic myelopathy were treated, including 42 males and 31 females, aged from 29 to 73 years old with a mean of 50.9 years old. The patients were divided into the simple operation group (34 cases) and the operation combined with traditional Chinese medicine group(39 cases) according to the idea of themselves. The anterior discectomy or subtotal corpectomy with internal fixation or posterior simple open-door decompression with lateral mass screw fixation were performed in the patients. Among them, 39 cases were treated with traditional Chinese medicine after surgery. The Japanese orthopedic association (JOA) score of spinal cord function, the improvement rate of neural function, the neck dysfunction index (NDI) score and the governor vessel stasis syndrome score were compared between two groups preoperative and postoperative 1 week, 1 month and the final follow-up respectively. The internal fixation and the condition of spinal cord decompression were observed by CT, MRI and X-rays before and after operation. RESULTS: All the operations were successful, no injuries such as dura mater, spinal cord and nerve root were found. All the wounds were healed without infection except one patient had a superficial infection. It was solved after intermittent debridement and anti-infective therapy. Hematoma occurred in 1 case, complicated with spinal cord compression, caused incomplete paralysis, and promptly performed the re-operation to remove the hematoma without any obvious sequelae. All the patients were followed up from 12 to 24 months, (14.6±0.8) months for simple operation group and (13.5±0.7) months for operation combined with traditional Chinese medicine group, and there was no significant difference(P>0.05). The scores of JOA, NDI and the governor's vessel stasis syndrome in simple operation group were 8.31±3.15, 29.91±4.52, 6.58±1.31 before operation, and 10.21±2.58, 18.67±4.31, 8.24±1.18 one week after operation, and 11.38±2.85, 16.11±3.18, 8.91±2.11 one month after operation, and 12.21±3.12, 14.61±3.28, 9.12±1.56 at final follow-up, respectively; and in operation combined with traditional Chinese medicine group were 8.29±3.47, 30.83±4.14, 6.38±1.81before operation, and 10.48±2.39, 17.59±5.14, 8.33±1.57 one week after operation, and 12.14±3.12, 13.14±3.21, 9.55±2.49 one month after operation, and 13.85±3.34, 12.11±2.51, 10.33±1.95 at final follow-up, respectively. Postoperative JOA , NDI, and the governor vessel stasis syndrome score of two groups were significantly higher than preoperativee(P<0.05). There was no significant difference in JOA, NDI, and the governor vessel stasis syndrome score between two groups one week after operation (P>0.05). The above items in operation combined with traditional Chinese medicine group was better than that of simple operation group one month and final follow-up after operation (P<0.05). The improvement rate of neural function in simple operation group was (67.59±10.78)%, and in operation combined traditional Chinese medicine group was (66.88±12.15)%, there was no significant difference between two groups(P>0.05). There were no complications such as internal fixation failure or re-dislocation of atlas by postoperative CT, MRI and X-rays examination. CONCLUSIONS: Spinal card decompression for the treatment of cervical spondylotic myelopathy can extend the spinal canal, relieve the compression of nerve, achieve the deoppilation of governor vessel, the regulation of qi and blood, the restore of Yangqi, combined with traditional Chinese medicine of activating blood removing stasis, warming yang and activating meridians, reinforcing liver benefiting kidney, which may obtain better clinical effect.

RESUMO

OBJECTIVE: To explore the effect and underlying mechanism of decompression(DE)combined with Governor Vessel(GV)electro-acupuncture(EA) on rats with acute severe upper cervical spinal cord compression injury. METHODS: Thirty SPF rats were randomly divided into 5 groups(control group A, B and experiment group C, D, E), 6 rats in each group. The model of acute severe upper cervical spinal cord compression injury were made by forcing a balloon catheter put in atlas pillow clearance. The group A was blank one, the group B put balloon catheter in atlas pillow clearance without forcing, and the group C, D, E sustained compressed for 48 h. The group C received electric acupuncture intervention, selecting the Baihui and Dazhui point, having the continuous wave and frequency of 2 Hz, with the treatment time of 15 min and continuous treatment for 14 d; the group D received methylprednisolone intervention, injected by caudal vein; the group E did not received any intervention again. The arterial blood and injured spinal cord tissue of all the rats were obtained after 14 days' treatment, and BBB score was used to evaluate the change of each group hind limbs motor function, the contents of platelet activating factor(PAF) in injured spinal cord tissue and blood serum were assess by ELISA method; the Caspase-9 expression for each group after 14 days' treatment was assess by Western blot method. RESULTS: BBB scores were(21.000±0.000) points at the 6 time points, that was, 1 h, 48 h after forcing in control group, 24 h, 3 d, 7 d, 14 d after treating in experiment group; the score of experimental groups (group C, D, E) were always lower than control groups(group A, B); compared with group E, group C and D were significantly higher(P<0.05); and there was no significant difference between group C and group D(P>0.05). The results of PAF by ELISA method to measure:the concentration of serum PAF, there was no statistical difference among group A, B, D, E (P>0.05), group C was lower than the other groups (P<0.05); the concentration of tissue PAF, there was no significant difference between group A and group B(P>0.05), group D was significantly higher than that of group A, B, and C(P<0.05), group E was the highest one than that of the other groups(P<0.05). Western blot med tests showed that the Caspase-9 protein expression in group A and B was similar (P>0.05), group C was higher than that of group A and B(P<0.05), group D was higher than group A, B and C(P<0.05), group E was the highest than that of group A, B, C and D (P<0.05). CONCLUSIONS: Decompression and Governor Vessel electro-acupuncture on acute severe upper cervical spinal cord compression injury had a better effect compare with decompression and methylprednisolone or simple decompression only, its mechanism may be related to lower the PAF levels and downregulating Caspase-9 protein expression in spinal injury tissue.

RESUMO

BACKGROUND: Decompressive laminectomy (DI) is a standard operation for lumbar spinal stenosis (LSS) patient with severe claudication symptoms for many years. However, patients whose symptom severity does not meet undergoing invasive surgery make therapeutic options into dilemma. Interspinous spacers (ISP) bridge the gap between surgical interventions and CC in management of LSS. In our study, we aim to systematically assess the two FDA-approved interspinous spacers for treatment of lumbar spinal stenosis: Superion versus X-STOP. METHODS: Electronic databases, including PubMed, Embase, MEDLINE, Cochrane Library were searched to retrieve clinical trials concerning the comparison between Superion and X-STOP in treatment for lumbar spinal stenosis before April 2017. The following outcome measures were extracted: (1) Zurich Claudication Questionnaire (ZCQ) patient satisfaction score, (2) axial pain severity, (3) extremity pain severity, (4) back-specific functional impairment, (5) reoperation, and (6) complication. The data analysis was conducted with Review Manager 5.3. RESULTS: Five randomized controlled trials (RCTs) with 1118 patients were included in this meta-analysis. The pooled analysis indicated that the Superion group is superior to X-STOP in axial pain severity (SMD: 0.03; 95% CI 0.15, 0.45; p < 0.0001, I2 = 41%, p = 0.16), ZCQ patient satisfaction score (SMD: 0.23; 95% CI 0.08, 0.38; p = 0.002, I2 = 0%, p = 0.61). However, Superion group showed similarity outcome in extremity pain severity (SMD: 0.18; 95% CI - 0.06, 0.43; p = 0.14, I2 = 62%, p = 0.05), back-specific functional impairment (SMD: 0.04; 95% CI - 0.10, 0.19; p = 0.56, I2 = 0%, p = 0.77), reoperation rate (RR: 1.10; 95% CI 0.82, 1.48; p = 0.51, I2 = 19%, p = 0.30), and complication (RR: 0.98; 95% CI 0.63, 1.53; p = 0.92, I2 = 0%, p = 0.83). CONCLUSION: Both the Superion and X-STOP interspinous spacers can relieve symptoms of LSS. In addition, the Superion spacer may represent a promising spacer for patient with LSS. As we know, the effectiveness and safety of ISP is still considered investigational and unfavor clinical results in the medical literature may continue to limit the appeal of IPS to many surgeons in the future. However, because of the advantage of IPS technique, it will win a wide place in the future degenerative lumbar microsurgery.

RESUMO

BACKGROUND: Nowadays, anterior cervical artificial disc replacement (ACDR) has achieved favorable outcomes in treatment for patients with single-level cervical spondylosis. However, It is still controversial that whether or not it will become a potent therapeutic alternation in treating 2 contiguous levels cervical spondylosis compared with anterior cervical decompression and fusion (ACDF). Therefore, we conducted a systematic review and meta-analysis to compare the efficacy and safety of ACDR and ACDF in patients with 2 contiguous levels cervical spondylosis. METHODS: According to the computer-based online search, PubMed, Embase, Web of Science, and Cochrane Library for articles published before July 1, 2017 were searched. The following outcome measures were extracted: neck disability index (NDI), visual analog scale (VAS) neck, VAS arm, Short Form (SF)-12 mental component summary (MCS), SF-12 physical component summary (PCS), overall clinical success (OCS), patient satisfaction (PS), device-related adverse event (DRAE), subsequent surgical intervention (SSI), neurological deterioration (ND), and adjacent segment degeneration (ASD). Methodological quality was evaluated independently by 2 reviewers using the Furlan for randomized controlled trial (RCT) and MINORS scale for clinical controlled trials (CCT). The chi-squared test and Higgin I test were used to evaluate the heterogeneity. A P < .10 for the chi-squared test or I values exceeding 50% indicated substantial heterogeneity and a random-effect model was applied; otherwise, a fixed-effect model was used. All quantitative data were analyzed by the Review Manager 5.2 (The Nordic Cochrane Centre, The Cochrane Collaboration, Copenhagen, Denmark). RESULTS: Nine RCTs and 2 CCT studies containing 2715 patients were included for this meta-analysis. The pooled analysis indicated that the ACDR group is superior to ACDF in NDI, VAS neck, PCS score, OCS, PS, DRAE, ASD, and SSI. However, the pooled results indicate that there was no significant difference in the ND, VAS arm and in MCS score. CONCLUSIONS: The present meta-analysis suggests that for bi-level cervical spondylosis, ACDR appears to provide superior clinical effectiveness and safety effects than ACDF. In the future, more high-quality RCTs are warranted to enhance this conclusion.

RESUMO

OBJECTIVE: To analyze the clinical outcome of kyphoplasty on costal pain which develops following thoracic osteoporotic compression fractures and evaluate the factors related to costal pain. METHODS: From May 2014 to May 2016, a total of 188 patients with thoracic osteoporotic compression fractures undergoing kyphoplasty were reviewed retrospectively. The patients were divided into two groups: the costal pain group included patients who had costal pain after a vertebral fracture and the no costal pain group included patients without costalgia. Visual analogue scale(VAS)and Oswestry Disability Index(ODI)of all patients were measured preoperatively and 3 days, 1 month, 6 months postoperatively respectively. Gender, age, the fracture level, bone mineral density, vertebral body fracture type, and fracture severity were compared between two groups, and the causes of costal pain were analyzed. RESULTS: Among 188 patients, 38 patients (20.2%) complained of costal pain with back pain. The mean follow-up time was 8.3 months (ranged from 6 to 15 months). The VAS and ODI score of two groups decreased after operation, and there was significant difference between pre-operation and post-operation(P<0.05). There was significant difference in VAS score and ODI score between two groups at 3 days and 1 month postoperatively (P<0.05). There was no significant difference in VAS score and ODI score between two groups at 6 months postoperatively (P<0.05). The incidence of applanation-type deformity and severe fracture in the costal group were higher. The fracture type and fracture severity showed significantly difference between two groups(P<0.05). CONCLUSIONS: The fracture type and fracture severity had significant relation to costal pain of thoracic osteoporotic compression fractures. The kyphoplasty effect on costal pain may not be effective, especially during early post-operation period.

RESUMO

OBJECTIVE: To investigate the meaning of pedicle exposure technique for screw fixation on atlas with the vertebral groove height less than 4 mm by using reconstructive computed tomography. METHODS: From April 2015 to June 2015, 84 pedicles of 51 patients with groove heights less than 4 mm were studied by digital reconstruction respectively. Parameters of atlas pedicle screw fixation were measured. RESULTS: Among the 51 cases, the vertebral groove height was (3.28±0.51) mm. Lateral mass heights, lateral mass widths and the transition area heights between lateral mass and posterior arch were fit for 3.5 mm screw implanting. Ideal pedicle screw trajectory lengths from 0° to 15° (0°, 5°, 10°, 15°) were (27.36±1.81), (27.01±1.68), (27.07±1.75), (27.48±1.72) mm, exposed trajectory lengths from 0° to 15°(0°, 5°, 10°, 15°) were(23.44±1.79), (23.87±1.84), (24.58±1.89), (25.56±2.01) mm, trajectory length of lateral mass was (20.78±2.05) mm. The mean CT values on 5 sections through pedicle trajectory and lateral mass trajectory were (701.89±141.48) HU and (599.11±137.33) HU, respectively. There were no significant differences between ideal pedicle trajectory lengths from 0° to 15°(P>0.05). Exposed trajectory lengths was significantly increased accompanying with medial angles increasing (P<0.05), and was longer than trajectory lengths of lateral mass (P<0.05). CT value of pedicle screws was higher than CT value of lateral mass screws significantly (P<0.01). CONCLUSIONS: Screws can be implanted in atlas with vertebral groove height less than 4 mm by using pedicle exposure technique. Few trajectory lengths will be sacrificed with favorable pull out strength due to adequate bone mass purchased.

RESUMO

OBJECTIVE: To investigate the clinical effects and operative options for the treatment of Forestier disease. METHODS: From June 2005 to May 2012, 8 patients with progressive dysphagia due to Forestier disease were treated through anterior approach, their clinical data were retrospective analyzed. There were 6 males and 2 females, aged from 65 to 83 years old with an average of 73 years. Among the patients, osteophytes removal was performed in 3 cases, osteophytes removal with discectomy and fusion was performed in 2 cases, osteophytes removal with corpectomy and fusion was performed in 3 cases. According to Bazaz dysphagia score to assess the improvement of the patients' symptoms before and after operation. RESULTS: All patients were followed up from 12 to 40 months with the mean of 18.5 months. Seven cases were asymptomatic and 1 case had mild symptom in the last follow-up. Radiographs showed the space enlargement between vertebral body and trachea. CONCLUSION: It is effective to treat patients with progressive dysphagia due to Forestier disease through surgical method. And the operative options depend on the stability of cervical spine and the neurological symptoms of the patients.

RESUMO

BACKGROUND: The footprint of most prostheses is designed according to Caucasian data. Total disc replacement (TDR) has been performed widely for cervical degenerative diseases in China. It is essential to analyze the match sizes of prostheses footprints and Chinese cervical anatomic dimensions in our study. METHODS: The anatomic dimensions of the C4-C7 segments of 138 patients (age range 16-77 years) in a Chinese population were measured by computed tomography scans. We compared the footprints of the most commonly used cervical disc prostheses (Bryan: Medtronic, Minneapolis, MN, USA; Prestige LP: Medtronic, Fridley, Minnesota, USA; Discover: DePuy, Raynham, MA, USA; Prodisc-C: Synthes, West Chester, PA, USA) in China with Chinese cervical anatomic dimensions and assessed the match of their size. RESULTS: The mismatch of available dimensions of prostheses and anatomic data of cervical endplates ranged from 17.03% (C4/C5, Prestige LP, Prodisc-C) to 57.61% (C6/C7, Discover) in the anterior-posterior (AP) diameter, and 35.51% (C4/C5, Prodisc-C, Prestige LP) to 94.93% (C6/C7, Bryan) in the center mediolateral (CML) diameter. About 21.01% of endplates were larger than the largest prostheses in the AP diameter and 57.25% in the CML diameter. All available footprints of prostheses expect the Bryan with an unfixed height, can accommodate the disc height (DH), however, 36.23% of the middle DH was less than the smallest height of the prostheses. The average disc sagittal angles (DSAs) of C4-C7 junctions were 5.04°, 5.15°, and 4.13° respectively. Only the Discover brand had a built-in 7° lordotic angle, roughly matching with the DSA. CONCLUSIONS: There is a large discrepancy between footprints of prostheses and Chinese cervical anatomic data. In recent years, possible complications of TDR related with mismatch sizes are increasing, such as subsidence, displacement, and heterotopic ossification. Manufacturers of prostheses should introduce or produce additional footprints of prostheses for Chinese TDR.

RESUMO

OBJECTIVE: To explore effectiveness and safety of segmental anterior cervical decompression in treating multi-level cervical myelopathy. METHODS: Twenty-four patients with four levels of cervical myelopathy were treated with segmental anterior cervical decompression (reservation of middle vertebrae, bone graft and plate-screws fixation). Among patients, there were 15 males and 9 females aged from 47 to 75 (averaged 57.9) years old. Preoperative, postoperative at 1 week and the latest following-up AP and lateral X-rays were used to observe bone union, displacement of implant, adjacent segment degeneration, changes of Cobb angle of fusion segment. JOA scoring were applied for evaluate recovery of nerve function. RESULTS: All operations were completed successfully, 2 cases ocurred hoarseness, and improved after treated symptomatically. Nineteen patients were followed up from 3.1 to 5.3 years with an average of 3.9 years. Bone union time ranged from 3 to 7 (averaged 4.5) months. No screw loosening and displacement occurred. Nine patients occurred titanium mesh subsidence in different degrees, and 4 of them subside >3 mm; four patients ocurred adjacent segment degeneration. Postoperative Cobb angle of fusion segment at 1 week (10.40±2.94)° was improved from preoperative (5.76±4.16)°, but decreased at the latest follow-up (8.57±2.82)°, and had significant meaning compared with preoperative (P<0.01). JOA score at the latest follow-up (14.6±1.1) was higher than that of before operation (8.2±1.9), and had siginificant differences (P<0.01). CONCLUSION: Segmental anterior cervical decompression for the treatment of multilevel cervical myelopathy has a high clinical operability, and plays an important role in recovering cervical curvature and nerve function based on completely decompression.

RESUMO

OBJECTIVE: To explore clinical effects of multi-segmental cervical spondylosis myelopathy through anterior approach by surgical treatment. METHODS: From September 2006 to September 2012, the data of 85 patients with multi segmental cervical spondylosis myelopathy were retrospectively analyzed. Among them, 48 cases were male, 37 cases were female, ranging the age from 34 to 86 years old (mean, 54.5 years old). Surgical procedure included anterior discectomy and fusion (19 cases), anterior secondary discectomy and fusion (45 cases) and anterior discectomy combined with anterior cervical corpectomy with fusion (21 cases). Bone fusion were evaluated by X-ray at the 3rd day after operation and following up. JOA score and improvement rate were compared. RESULTS: All patients were followed up from 6 to 30 months with an average of 18 months. Decompression were done throughly during operation and good intervertebral space height and cervical curvature were obtained. X-ray showed nonunion in 3 cases, and improvement rate was 96%. JOA score after operation was higher than before operation, and had significant differences (P < 0.05). Fifty-six cases got excellent results, 16 moderate, 9 effective and 4 invalid according to JOA scores. CONCLUSION: Surgical procedures for cervical spondylosis myelopathy should be chosen reasonably in accordance with sympotoms, signs, imaging data, so as to obtain good results in decompression, recoving intervertebral height and cervical curature, improving fusion rate.

RESUMO

OBJECTIVE: To research the correlation between surgical treatment for atlantoaxial dislocation and dredging Governor vessel. METHODS: From June 2004 to June 2010,113 patients were reviewed, including 65 males and 48 females, with the mean age of 42.6 years (ranged, 8 to 64 years). All the patients were classified and treated by TOI clinical classification which included traction and decompression and reduction, and inter fixation fusion by surgery. The SAC (space available for the cord), Governor vessel Yuzu score, JOA score, NDI score (cervical spine dysfunction index) before treatment were compared with those of after treatment. RESULTS: The SAC in each group before treatment were (13.34 +/- 3.21), (10.43 +/- 2.42), (7.89 +/- 3.14), (10.50 +/- 0.71) mm respectively, the last follow-up of (16.02 +/- 1.42), (15.34 +/- 1.87), (14.49 +/- 1.58), (12.50 +/- 0.71) mm; Governor vessel Yuzu score before treatment were (8.37 +/- 1.87), (6.87 +/- 1.35), (5.17 +/- 1.13), (7.50 +/- 0.71) respectively, the last follow-up of (10.59 +/- 0.94), (10.25 +/- 1.01), (8.41 +/- 1.31), (9.0 +/- 0); JOA, NDI score significantly improved compared with that of before treatment. CONCLUSION: Atlantoaxial dislocation confirmed and treated by TOI clinical classification can effectively relieve the nerve function and Governor vessel Yuzu syndrome, and show that surgical treatment is closely related with dredging the Governor vessel.
