ObjectivesTo systematically review the efficacy of repetitive transcranial magnetic stimulation (rTMS) on rehabilitation of unilateral neglect in stroke patients.MethodsPubMed, The Cochrane Library, PEDro, EMbase, CNKI, WanFang Data and VIP databases were searched online for randomized controlled trials (RCTs) of rTMS on rehabilitation of unilateral neglect in stroke patients from inception to March 2017. Two reviewers independently screened literature, extracted data and assessed the quality of included studies. Meta-analysis was then performed by using RevMan 5.3 software.ResultsA total of 12 RCTs involving 303 patients were included. The results of meta-analysis showed that: the stimulate group was superior to the control group in line bisection test (MD=–5.54, 95%CI –6.79 to –4.29, P<0.000 01), line cancellation test (MD=–3.75, 95%CI –4.60 to –2.90,P<0.000 1) and star cancellation test (MD=–22.94, 95%CI –26.52 to –19.35,P<0.000 01). However, there was no significant difference in the score of the modified Barthel index between two groups (MD=3.91, 95%CI–9.52 to 17.34,P=0.57).ConclusionsrTMS appears to improve the symptoms of unilateral neglect in stroke patients. Due to limited quality and quantity of the included studies, more high quality studies are needed to verify above conclusions.
Objective To analyze the perioperative efficacy of enhanced recovery after surgery (ERAS) in the treatment of lumbar disc herniation using unilateral biportal endoscopy technique. Methods A total of 55 patients who received unilateral biportal endoscopy technique for the treatment of lumbar disc herniation in Tianjin Hospital between January and December 2020 were selected and randomly divided into the traditional group and the ERAS group according to random number table method. The routine inpatient care management was adopted in the traditional group, while the holistic integrated care plan was formulated in the ERAS group according to the multidisciplinary collaboration of the accelerated rehabilitation plan. The first postoperative exhaust time, the first time out of bed, length of hospital stay, hospital costs, Visual Analogue Scale (VAS) scores before operation, one day and three days after operation, Oswestry Disability Index (ODI) scores before operation and one month after operation, and the excellent and good rate of modified MacNab efficacy one month after operation were compared between the two groups. Results There were 28 cases in the traditional group and 27 cases in the ERAS group. The first postoperative exhaust time [(2.31±1.02) vs. (3.19±0.87) h], the first postoperative ambulation time [(1.06±0.40) vs. (2.00±0.53) d], length of hospital stay [(3.8±0.8) vs. (4.6±0.8) d], and hospital cost [(32.18±9.10) thousand yuan vs. (39.81±11.10) thousand yuan] in the ERAS group were all less than those in the traditional group, and the differences were statistically significant (P<0.05). The VAS scores of the ERAS group one day after operation (3.2±0.8 vs. 4.1±0.8) and three days after operation (1.4±0.5 vs. 1.7±0.5) were lower than those of the traditional group (P<0.05). The ODI scores of the ERAS group one month after operation was lower than that of the traditional group (13.3±4.0 vs. 16.6±4.8, P<0.05). In the modified MacNab efficacy evaluation one month after surgery, there was no significant difference in the excellent and good rate between the ERAS group and the traditional group (96.3% vs. 96.4%, P>0.05). Conclusions ERAS regimen can significantly accelerate the patients’ recovery, including shortening the first exhaust time, facilitating early ambulation, and reducing the hospital stay and hospitalization expenses. Meanwhile, ERAS regimen can effectively reduce the postoperative pain of the patients, and promote early functional recovery.
Objective To evaluate the effectiveness of spinal canal decompression assisted by unilateral biportal endoscopy (UBE) and percutaneous uniplanar pedicle screw internal fixation in the treatment of lumbar burst fractures with neurological symptoms. Methods Between June 2021 and December 2022, 10 patients with single level lumbar burst fracture with neurological symptoms were treated with spinal canal decompression assisted by UBE and percutaneous uniplanar pedicle screw internal fixation. There were 7 males and 3 females with an average age of 43.1 years (range, 21-57 years). The injured vertebrae located at L1 in 2 cases, L2 in 4 cases, L3 in 3 cases, and L4 in 1 case. There were 7 cases of AO type A3 fractures and 3 cases of AO type A4 fractures. The total operation time, the time of operation under endoscopy, and complications were recorded. Pre- and post-operative visual analogue scale (VAS) score and American Spinal Injury Association (ASIA) scale (grading A-E corresponding to assigning 1-5 points for statistical analysis) were used to evaluate effectiveness. X-ray film and CT were performed to observe the fracture healing, and the ratio of anterior vertebral body height, Cobb angle, and rate of spinal canal invasion were measured to evaluate the reduction of fracture.Results All operations was successfully completed, and the spinal canal decompression and the bone fragment in spinal canal reduction completed under the endoscopy. Total operation time was 119 minutes on average (range, 95-150 minutes), and the time of operation under endoscopy was 46 minutes on average (range, 35-55 minutes). There was no complication such as dural sac, nerve root, or blood vessel injury during operation. All incisions healed by first intention. All patients were followed up 18.7 months on average (range, 10-28 months). The VAS score after operation significantly decreased when compared with that before operation (P<0.05), and further improved at last follow-up (P<0.05). The ASIA scale after operation significantly improved when compared with that before operation (P<0.05), and there was no significant difference (P>0.05) in the ASIA scale between at 1 week after operation and at last follow-up. The imaging examination showed that the screw position was good and the articular process joint was preserved. During follow-up, there was no loosening, fracture, or fixation failure of the internal fixation. The ratio of anterior vertebral body height and Cobb angle significantly improved, the rate of spinal canal invasion significantly decreased after operation (P<0.05), and without significant loss of correction during the follow-up (P>0.05). Conclusion Spinal canal decompression assisted by UBE and percutaneous uniplanar pedicle screw fixation is a feasible minimally invasive treatment for lumbar burst fractures with neurological symptoms, which can effectively restore the vertebral body sequence, as well as relieve the compression of spinal canal, and improve the neurological function.
ObjectiveTo investigate the effectiveness of synchronous unilateral percutaneous kyphoplasty (PKP) in the treatment of double noncontiguous thoracolumbar osteoporotic vertebral compression fracture (OVCF). MethodsBetween December 2018 and September 2020, 27 patients with double noncontiguous thoracolumbar OVCF were treated by synchronous unilateral PKP. There were 11 males and 16 females, with an average age of 75.4 years (range, 66-92 years). The fractures were caused by falls in 22 cases and sprains in 5 cases. The time from injury to hospital admission was 0.5-7.0 days, with an average of 2.1 days. The fractured vertebrae located at T9 in 2 cases, T10 in 3 cases, T11 in 10 cases, T12 in 15 cases, L1 in 12 cases, L2 in 6 cases, L3 in 4 cases, and L4 in 2 cases. The volume of bone cement injected into each vertebral body, operation time, and intraoperative fluoroscopy times were recorded. Anteroposterior and lateral X-ray films of thoracolumbar spine were taken to observe the anterior height of the injured vertebra, the Cobb angle of kyphosis, and the diffusion and good distribution rate of bone cement in the thoracolumbar spine. Visual analogue scale (VAS) score and Oswestry disability index (ODI) were used to evaluate the pain and functional improvement. ResultsAll operations completed successfully. The operation time was 34-70 minutes, with an average of 45.4 minutes. The intraoperative fluoroscopy was 21- 60 times, with an average of 38.6 times. The volume of bone cement injected into each vertebral body was 2-9 mL, with an average of 4.3 mL. All patients were followed up 6-21 months, with an average of 11.3 months. X-ray film reexamination showed that the anterior height of the injured vertebra and Cobb angle at each time point after operation were significantly improved than those before operation (P<0.05), and there was no significant difference between different time points after operation (P>0.05). The distribution of bone cement was excellent in 40 vertebral bodies, good in 13 vertebral bodies, and poor in 1 vertebral body, and the excellent and good rate was 98.1% (53/54). The pain of all patients significantly relieved or disappeared, and the function improved. The VAS score and ODI at each time point after operation were significantly lower than those before operation (P<0.05), and there was no significant difference between different time points after operation (P>0.05).ConclusionFor the double noncontiguous thoracolumbar OVCF, the synchronous unilateral PKP has the advantages of simple puncture, less trauma, less intraoperative fluoroscopy, shorter operation time, satisfactory distribution of bone cement, etc. It can restore the height of the vertebral body, correct the kyphotic angle, significantly alleviate the pain, and improve the function.
ObjectiveTo evaluate early effectiveness of posterior 180-degree decompression via unilateral biportal endoscopy (UBE) in the treatment of lumbar spinal stenosis (LSS) combined with Michigan State University (MSU)-1 lumbar disc herniation (LDH). MethodsA retrospective analysis was conducted on clinical data from 33 patients with LSS combined with MSU-1 LDH, who met selection criteria and were treated between March 2022 and January 2024. All patients underwent UBE-assisted 180-degree spinal canal decompression. The cohort comprised 17 males and 16 females, aged 37-82 years (mean, 67.1 years). Preoperative presentations included bilateral lower limbs intermittent claudication and radiating pain, with disease duration ranging from 5 to 13 months (mean, 8.5 months). Affected segments included L3, 4 in 4 cases, L4, 5 in 28 cases, and L5, S1 in 1 case. LSS was rated as Schizas grade A in 4 cases, grade B in 5 cases, grade C in 13 cases, and grade D in 11 cases. LDH was categorized as MSU-1A in 24 cases, MSU-1B in 2 cases, and MSU-1AB in 7 cases. Intraoperative parameters (operation time, blood loss) and postoperative hospitalization length were recorded. The visual analogue scale (VAS) score and Oswestry Disability Index (ODI) were used to assess the lower limb pain and functional outcomes after operation. Clinical efficacy was evaluated at last follow-up via modified MacNab criteria. Quantitative radiological assessments included dural sac cross-sectional area (DSCA) measurements and spinal stenosis grading on lumbar MRI. Morphological classification of lumbar canal stenosis was determined according to the Schizas grading, categorized into four grades. Results The operation time was 60.4-90.8 minutes (mean, 80.3 minutes) and intraoperative blood loss was 13-47 mL (mean, 29.9 mL). The postoperative hospitalization length was 3-5 days (mean, 3.8 days). All patients were followed up 12-16 months (mean, 13.8 months). The VAS score and ODI improved at immediate and 3, 6, and 12 months after operation compared to before operation, and the differences between different time points were significant (P<0.05). At last follow-up, the clinical efficacy assessed by the modified MacNab criteria were graded as excellent in 23 cases, good in 9 cases, and poor in 1 case, with an excellent and good rate of 96.97%. Postoperative lumbar MRI revealed the significant decompression of the dural sac in 32 cases, with 1 case showing inadequate dural expansion. DSCA measurements confirmed progressive enlargement and stenosis reduction over time. The differences were significant (P<0.05) before operation, immediately after operation, and at 6 months after operation. At 6 months after operation, Schizas grading of spinal stenosis improved to grade A in 27 cases and grade B in 6 cases. ConclusionPosterior 180-degree decompression via UBE is a safe and feasible strategy for treating LSS combined with MSU-1 LDH, achieving effective neural decompression while preserving intervertebral disc integrity.

The current unilateral biportal endoscopy (UBE) technique was originated from Argentina and developed in South Korea, which was rapidly growing and popularizing in China. The adoption of spinal endoscopy, using small cameras placed inside body with continuous water irrigation, providing better surgical field with less tissue dissection and quicker recovery for patients. As with other disciplines, the use of spinal endoscopy in spinal surgery will become increasingly widespread. UBE technique will promote the popularization of spinal endoscopy in China with monoportal endoscopy technique. At the same time, biportal endoscopy has better expansibility, the application of accessory incision may provide solution for more complicated spinal disease. Chinese spine surgeon should better understand the trends in spinal endoscopy, seize the opportunity of the rapidly evolving in spinal healthcare, and to promote the popularization of UBE across the globe.
ObjectiveTo investigate the effect of one-stage posterior reduction single nail and rod fixation combined with the anterior operation on lower cervical fracture-dislocation combined with unilateral locked facet.MethodsA retrospective analysis of 28 patients with lower cervical fracture-dislocation combined with unilateral locked facet who underwent one-stage posterior-anterior approach surgery between June 2012 and March 2017 were conducted. The Cobb angle, vertebral body horizontal displacement, height of intervertebral space, recovery of nerve function and operative complications were observed before and after operation.ResultsAll patients were followed up for 12-24 months, with an average of (18.9±4.7) months. All the patients received good reposition after operation without complications such as large blood vessels, trachea, esophagus, spinal dura mater injury and so on. The incisions healed well in all patients. Postoperative complications: postoperative hoarseness and dysphagia occured in 3 cases, pharynx and larynx pain in 8 cases, pulmonary infection in 1 case, and hyponatremia in 2 cases; all patients recovered after the related symptomatic treatment. Postoperative X-ray showed that all the patients were completely corrected without residual small joint semi dislocation and kyphosis. No spinal cord or nerve injury aggravators occurred after surgery. The neurological function of all patients was improved to different degrees 12 months after operation. American Spinal Cord Injury Association (ASIA) classification showed that, of the 6 cases classified as type B preoperatively, 4 cases turned into type C and 2 cases into type D postoperatively; of the 13 cases classified as type C preoperatively, 10 cases turned into type D and 3 into type E postoperatively; and all the 8 cases classified as type D preoperatively turned into type E postoperatively. The ASIA scores increased by 1-2 levels compared with those before operation (P<0.05). The height of cervical intervertebral space, physiological curvature and cervical stability of all patients were well maintained 7 days and 12 months after operation, which were significantly improved compared with those before operation (P<0.05). There was no significant difference between the two follow-up visits at 7 days and 12 months after operation. The Japanese Orthopaedic Association score at 12 months after operation (14.6±2.3) was significantly better than that before operation (6.8±2.6), and the average improvement rate was (79.6±18.8)% (P<0.05). No complications such as screw loosening, fracture or displacement occurred during follow-up.ConclusionOne-stage posterior reduction single nail and rod fixation combined with the anterior operation is safe and effective for the treatment of lower cervical fracture-dislocation combined with unilateral locked facet.
Objective To analyze the early effectiveness of unilateral biportal endoscopic discectomy (UBED) combined with annulus fibrosus suture in the treatment of lumbar disc herniation (LDH). Methods The clinical data of 19 patients with LDH treated with UBED and annulus fibrosus suture between October 2020 and October 2021 were retrospectively analyzed. There were 12 males and 7 females with an average age of 39.1 years (range, 26-59 years). The operative segment was L4, 5 in 13 cases, and L5, S1 in 6 cases. The mean disease duration was 6.7 months (range, 3-15 months). Preoperative neurological examination showed that muscle strength, sensation, and tendon reflex weakened or disappeared in varying degrees. Single annulus fibrosus suture (14 cases) or anchor assisted annulus fibrosus suture (5 cases) was selected according to the location of annulus fibrosus tears. Visual analogue scale (VAS) score was used to assess the low back and leg pain before operation and at 3 days, 3 months, and 6 months after operation. Oswestry disability index (ODI) was used to evaluate the function recovery of lumbar spine before operation and at 3 days, 3 months, and 6 months after operation. At 3 days and 3 months after operation, MRI was used to examine the removal of nucleus pulposus and decompression of nerve root. MacNab criteria was used to evaluate the effectiveness at 6 months after operation and the recovery of nerve root function was recorded. Results All operations were successfully completed with a mean operation time of 52.7 minutes (range, 40-75 minutes). There was no complication such as nerve injury, spinal cord hypertension syndrome, or dural sac tear during operation, and no complication such as infection, aggravation of nerve damage, or cerebrospinal fluid leakage after operation. All the patients were followed up 6-10 months (mean, 8.2 months). Postoperative MRI showed that the herniated disc was completely removed and nerve roots were fully decompressed. During the follow-up, there was no recurrence of disc herniation. The VAS scores of low back pain and leg pain and ODI at each time point after operation significantly improved when compared with those before operation, and those at 6 months after operation further improved than those at 3 days and 3 months after operation, all showing significant differences (P<0.05). At 6 months after operation, MacNab standard was used to evaluate the effectiveness, and the results were excellent in 14 cases, good in 4 cases, and fair in 1 case, with an excellent and good rate of 94.7%. Neurological examination showed that the sensation and muscle strength of the affected nerve root innervated area recovered significantly when compared with those before operation (P<0.05); the recovery of tendon reflex was not obvious, showing no significant difference when compared with that before operation (P>0.05). ConclusionUBED combined with annulus fibrosus suture is a safe and effective technique for LDH and early effectiveness is satisfactory.
