RESUMO

BACKGROUND: To identify the differences of lumbar lordosis (LL) and sacral slope (SS) angles between two types of postoperative lumbar disc re-herniation, including the recurrence of same level and adjacent segment herniation (ASH). METHODS: We searched the medical records of lumbar disc herniation (LDH) patients with re-herniation with complete imaging data (n = 58) from January 1, 2013 to December 30, 2020 in our hospital. After matching for age and sex, 58 patients with LDH without re-herniation from the same period operated by the same treatment group in our hospital were served as a control group. Re-herniation patients were divided into two groups, same-level recurrent lumbar disc herniation group (rLDHG) and adjacent segment herniation group with or without recurrence (ASHG). The preoperative, postoperative and one month after operation LL and SS were measured on standing radiographs and compared with the control group by using t-test, ANOVA, and rank-sum test. Next, we calculated the odds ratios (ORs) by unconditional logistic regression, progressively adjusted for other confounding factors. RESULTS: Compared with the control group, the postoperative LL and SS were significantly lower in LDH patients with re-herniation. However, there were no differences in LL and SS between ASHG and rLDHG at any stage. After progressive adjustment for confounding factors, no matter what stage is, LL and SS remained unassociated with the two types of re-herniation. CONCLUSIONS: Low postoperative LL and SS angles are associated with degeneration of the remaining disc. Low LL and SS may be independent risk factors for re-herniation but cannot determine type of recurrence (same or adjacent disc level).

RESUMO

BACKGROUND: Annulus fibrosus-endplate (AF-EP) junction lesions are important determinants for lumbar disc herniation (LDH). Utilizing biportal endoscopic spinal surgery (BESS), we introduce a novel repair method using bioabsorbable PushLock anchors with suture fibers to stretch disconnected AF tissues to the vertebral cortex. METHODS: The viewing and working portals are established to excise herniated disc materials causing radiculopathy. Through the working portal, a suture strand is passed through the intact AF tissue near the lesion and retrieved using the Suture Crossing Device. Then, the knotless suture limbs are secured into the cortical bone socket of the vertebral body with a PushLock anchor. CONCLUSION: The procedure is a simple, safe, and feasible knotless suturing technique for the treatment of LDH with AF-EP junction lesions.

RESUMO

Lumbar radiculopathy due to impingement of nerve roots from facet hypertrophy and/or disc herniation can often coincide with vertebrogenic low back pain. This is demonstrated on MRI with foraminal stenosis and Modic changes. We examine the potential of using a combination of basivertebral nerve ablation (BVNA) and lumbar laminotomy as an alternative to traditional spinal fusion in specific patient populations. This unique combination of surgical techniques has not been previously reported in the medical literature. We report a man in his late 30s with chronic low back pain and lumbar radiculopathy, treated with BVNA and concurrent laminotomy. The patient reported progressive improvements in his mobility and pain over the next 2 years. We discuss the advantages of using this technique for lumbar radiculopathy and Modic changes compared with conventional surgical modalities.

RESUMO

PURPOSE: We aimed to evaluate the effect of cervical disc herniation (CDH) and lumbar disc herniation (LDH) on female sexual functioning before and after surgical intervention. METHODS: The current study was conducted from February 2022 to February 2023. A total of 100 sexually active female patients in their reproductive phase who were diagnosed with CDH and LDH based on physical examination and previous magnetic resonance imaging (MRI) results, as well as 50 healthy females, were enrolled. The female subjects were evaluated using the validated Arabic version of the female sexual function index (ArFSFI), a 0 to 10 visual analogue scale (VAS), the Oswestry disability index (ODI) and Beck's depression index (BDI). RESULTS: The baseline ArFSFI domains and total scores were greatest in the controls, followed by the CDH group. The ArFSFI domains and total scores were greatest in the control group, followed by the postoperative ArFSFI domains and total scores in the cervical group. The variations in satisfaction, pain, and overall ArFSFI ratings were significant across research groups. The difference in desire, arousal, lubrication, and orgasm was substantial in the lumbosacral group, but there were no significant changes between the cervical and control groups. Postoperatively, ArFSFI domains and overall scores improved in both of the cervical and lumbar groups. Both research groups' ODI score and grade improved after surgery. Finally, both groups' BDI score and grade improved after surgery. CONCLUSION: Female sexual dysfunctions caused by CDH and LDH improved considerably after surgery.

RESUMO

PURPOSE: The following study aimed to determine the existence of blood biomarkers in symptomatic patients with or without lumbar Modic changes (MC). METHODS: A cross-sectional sub-analyses of a prospective cohort was performed. Fasting blood samples were collected from patients with and without lumbar MC who had undergone spinal fusion or microdiscectomy. An 80-plex panel and CCL5/RANTES were used to assess preoperative plasma cytokine concentrations. Patient demographics and imaging phenotypes were also assessed. RESULTS: Thirty-one subjects were analysed (n = 18 no MC; n = 13 MC). No significant differences were found in age, sex, body mass index, smoking and alcohol history, and surgical procedure (i.e. fusion, decompression) between the two groups (p > 0.05). Several statistically significant blood biomarkers in MC patients were identified, including elevated levels of C-C Motif Chemokine Ligand 5 (CCL5, p = 0.0006), while Macrophage Migration Inhibitory Factor (MIF) was significantly lower (p = 0.009). Additionally, C-X-C Motif Chemokine Ligand 5 (CXCL5, p = 0.052), Pentraxin 3 (PTX3, p = 0.06) and Galectin-3 (Gal-3, p = 0.07) showed potential relevance. Moreover, MC patients exhibited significantly higher levels of disc degeneration (p = 0.0001) and displacement severity (p = 0.020). Based on multivariate analyses and controlling for disc degeneration/displacement, CCL5 (OR 1.02; 95% CI 1.002-1.033; p = 0.028) and MIF (OR 0.60; 95% CI 0.382-0.951; p = 0.030) were independently associated with MC patients. CONCLUSION: This "proof-of-concept" study is the first to identify specific and significantly circulating blood biomarkers associated with symptomatic patients with lumbar MC, independent of disc alterations of degeneration and/or bulges/herniations. Specifically, differences in CCL5 and MIF protein levels were significantly noted in MC patients compared to those without MC.

RESUMO

OBJECTIVE: This study aims to evaluate the effects of total intravenous anesthesia (propofol), volatile anesthesia (desflurane), and spinal anesthesia on intraocular pressure (IOP) during lumbar disc herniation surgery in the prone position. PATIENTS AND METHODS: This randomized controlled trial was conducted between January 2022 and January 2023. The study included 75 patients with lumbar disc herniation between the ages of 18-75, with the American Society of Anesthesiologists (ASA) 1-2. The patients were randomly divided into 3 groups: propofol, desflurane, and spinal. IOP was measured at 5-time points throughout surgery, including baseline (T1), 10 minutes after anesthesia (T2), 10 minutes after prone positioning (T3: early prone), 30 minutes after prone positioning (T4: late prone), and 10 minutes after returning to the supine position (T5). Hemodynamic parameters were measured at these time points. Hemoglobin and hematocrit values were measured preoperatively and on the first postoperative day. RESULTS: There were 25 patients in each group. The groups were similar in terms of all characteristics except for weight and body mass index, which were lower in the spinal group. Propofol recipients had significantly higher T3 (prone) IOP compared to desflurane recipients (p = 0.001). We found no significant differences between groups in terms of T1, T2, T4, and T5 IOP. Multivariable linear regression revealed that diabetes mellitus (p = 0.016) and high T1 IOP (p = 0.001) were independently associated with higher T3 IOP. In addition, we found that the desflurane (p < 0.001) and spinal (p = 0.002) groups had significantly lower T3 IOP compared to propofol recipients after adjusting for diabetes mellitus and T1 IOP. CONCLUSIONS: Our findings suggest that volatile anesthesia (desflurane) and spinal anesthesia are linked to lower IOP in the prone position among patients undergoing spinal surgery, in comparison to those receiving total intravenous anesthesia. There is a need to test the results with more comprehensive, population-based studies in different patient groups. ClinicalTrials gov ID: NCT06070480.

RESUMO

OBJECTIVE: To observe the residual of lumbago and leg pain with contained type (CT) and non-contained type (NCT) lumbar disc herniation (LDH) after transforaminal endoscopic treatment, and to explore the role of hypoxia-inducible factor-1α(HIF-1α) and transient receptor potential vanillate 1(TRPV1) pathway. METHODS: A total of 68 single-segment LDH patients were selected from July 2021 to October 2022, including 44 males and 24 females;aged 26 to 67 years old with an average of(43.63±11.94) years old;course of disease was 4 to 36 (18.91±10.34) months;body mass index was (24.45±4.00) kg·m-2;there were 7 cases of L3,4 segments, 32 cases of L4,5 segments, and 29 cases of L5S1 segments. All of them were performed with percutaneous intervertebral endoscopic extraction of nucleus pulposus and were divided into contained group(CT group) and non-contained group (NCT group) with 34 cases respectively according to the integrity of outer layer of fibrous annulus observed during operation. A total of 17 patients who underwent open surgery for scoliosis or vertebral fracture were selected as control group, including 12 males and 5 females;aged 21 to 65 years old with an average of (39.41±12.80) years old;body mass index was (24.86±4.11) kg·m-2. The relative mRNA expression quantity of HIF-1α, TRPV1 in nucleus pulposus were measured by quantitative real-time PCR. The contents of neurokinin 1 receptor (NK1R), nerve growth factor (NGF), vascular endothelial growth factor (VEGF) in nucleus pulposus and the serum substance P (SP) and calcitonin gene-related peptide (CGRP) were detected by enzyme linked immunosorbent assay (ELISA). The threshold of lumbar tenderness was detected by a pressure pain meter. The degree of lumbago and lumbar function were evaluated by visual analog scale (VAS) and Oswestry disability index (ODI) separately. The residual rate of postoperative lumbago and leg pain was assessed. RESULTS: The mRNA relative expression quantity of HIF-1α and TRPV1, and the contents of NK1R, NGF and VEGF in nucleus pulposus, and the levels of serum SP and CGRP before surgery in the NCT group were higher than those in the CT group(P<0.05), and those in the CT group were higher than the control group(P<0.05). At day 7 after surgery, the serum SP and CGRP levels, lumbago and leg pain VAS scores and lumbar ODI index in two LDH groups were lower than before surgery (P<0.05), and those in the NCT group were higher than the CT group(P<0.05), and the threshold of lumbar tenderness in the NCT group was lower than the CT group(P<0.05). The differences of lumbago and leg pain VAS scores, lumbar ODI index and lumbar tenderness threshold between preoperative and postoperative 7 days in the NCT group were lower than those in the CT group(P<0.05). The residual rate of lumbago and leg pain at 7 days after surgery in the NCT group was higher than that in the CT group(P<0.05). CONCLUSION: HIF-1α and TRPV1 pathway promoted the excessive production of NGF, VEGF, NK1R in nucleus pulposus and serum neuropeptides SP and CGRP, which may lead to the higher residual rate of lumbago and leg pain with non-contained lumbar disc herniation postoperative.

RESUMO

OBJECTIVE: The Isobar TTL dynamic fixation system has demonstrated favorable outcomes in the short-term treatment of lumbar degenerative disc diseases (LDDs). However, there is a paucity of extensive research on the long-term effects of this system on LDDs. This study aimed to evaluate the long-term clinical and radiological outcomes of patients with LDDs who underwent treatment utilizing the Isobar TTL dynamic fixation system. METHODS: The study analyzed the outcomes of 40 patients with LDDs who underwent posterior lumbar decompression and received single-segment Isobar TTL dynamic internal fixation at our hospital between June 2010 and December 2016. The evaluation of clinical therapeutic effect involved assessing postoperative pain levels using the visual analogue scale (VAS) and Oswestry disability index (ODI), both before surgery, 3 months after, and the final follow-up. To determine the preservation of functional motion in dynamically stable segments, we measured the range of motion (ROM) and disc height of stabilized and adjacent segments preoperatively and during the final follow-up. Additionally, we investigated the occurrence of adjacent segment degeneration (ASD). RESULTS: Forty patients were evaluated, with an average age of 44.65 years and an average follow-up period of 79.37 months. Fourteen patients belonged to the spondylolisthesis group, while the remaining 26 were categorized under the stenosis or herniated disc group. The preoperative ROM of the stabilized segment exhibited a significant reduction from 8.15° ± 2.77° to 5.00° ± 1.82° at the final follow-up (p < 0.001). In contrast, there was a slight elevation in the ROM of the adjacent segment during the final follow-up, increasing from 7.68° ± 2.25° before surgery to 9.36° ± 1.98° (p < 0.001). The intervertebral space height (IH) in the stabilized segment exhibited a significant increase from 10.56 ± 1.99 mm before surgery to 11.39 ± 1.90 mm at the one-week postoperative follow-up (p < 0.001). Conversely, there was a notable decrease in the IH of the adjacent segment from 11.09 ± 1.82 mm preoperatively to 10.86 ± 1.79 mm at the one-week follow-up after surgery (p < 0.001). The incidence of ASD was 15% (6/40) after an average follow-up period of 79.37 months, with a rate of 15.38% (4/26) in the stenosis or herniated disc group and 14.29% (2/14) in the spondylolisthesis group; however, no statistically significant difference was observed in the occurrence of ASD among these groups (p > 0.05). CONCLUSION: The Isobar TTL dynamic fixation system is an effective treatment for LDDs, improving pain relief, quality of life (QoL) and maintaining stabilized segmental motion. It has demonstrated excellent long-term clinical and radiographic results.

RESUMO

OBJECTIVE: The aim of this study was to assess the impact of high-quality evidence supporting surgical treatment of lumbar disc herniation (LDH) on healthcare practice in the Netherlands by examining changes in healthcare utilisation, including the timing of surgery, and the healthcare costs for patients with LDH. DESIGN: A retrospective, cross-sectional study was performed using population-based, longitudinal data obtained from the Dutch Healthcare Authority (2007-2020) and NIVEL's primary care (2012-2020) administrative databases. SETTING: The study was conducted within the healthcare system of the Netherlands. PARTICIPANTS: We included adults (≥18 years) who visited a Dutch hospital or a general practitioner (GP) for lumbar degenerative disc disease. Patients with LDH were identified based on registered diagnosis code, type of surgery (discectomy) and age (<56 years). MAIN OUTCOME MEASURES: The primary outcome measure was the difference in the annual number of LDH procedures following the publication of evidence-based guidelines in 2009 (comparing the periods 2007-2009 to 2017-2019). Secondary outcome measures focused on the timing of surgery and associated healthcare costs. To validate the outcomes, secondary outcomes also include the number of discectomies and the number of procedures in the younger age group (discectomies, laminectomies, and fusion surgery). RESULTS: The number of patients suffering from LDH increased from 55 581 to 68 997 (+24%) between 2007 and 2019. A decrease was observed in the annual number of LDH procedures (-18%), in the number of discectomies (-22%) and in the number of procedures for patients aged <56 years (-18%). This resulted in lower healthcare costs by €10.5 million annually. In 2012, 31% of all patients <56 years had surgery before 12 weeks from diagnosis at the GP, whereas 20% did in 2019. CONCLUSIONS: Healthcare utilisation for LDH changed tremendously in the Netherlands between 2007 and 2020 and seemed to be associated with the publication and implementation of evidence-based guidelines. The observed decrease in the number of procedures has been accompanied by a corresponding reduction in healthcare costs. These findings underscore the importance of adhering to evidence-based guidelines to optimise the management of patients with LDH.

RESUMO

OBJECTIVE: To explore clinical outcomes and bone resection of interlaminar fenestration decompression and unilateral biportal endoscopic (UBE) technique in treating lumbar disc herniation(LDH). METHODS: A retrospective study was performed on 105 patients with single-level LDH treated from December 2019 to December 2021. Fifty-four patients in UBE group,including 32 males and 22 females,aged from 18 to 50 years old with an average of(38.7±9.3) years old,were treated with UBE,29 patients with L4,5 and 25 patients with L5S1. There were 51 patients in small fenestration group,including 27 males and 24 females,aged from 18 to 50 years old with an average of (39.9±10.0) years old,were treated with small fenestration,25 patients with L4,5 and 26 patients with L5S1. Perioperative indexes,such as operation time,postoperative time of getting out of bed and hospital stay were observed and compared between two groups. Visual analogue scale (VAS) and Oswestry disability index (ODI) were compared between two groups before operation and 1,3,6 and 12 months after operation,respectively;and modified MacNab evaluation criteria was used to evaluate clinical efficacy. Amount of bone resection and retention rate of inferior articular process laminoid complex were compared between two groups. RESULTS: All 105 patients were successfully completed operation. Both of two groups were followed up from 6 to 12 months with an average of (10.69±2.49) months. Operation time,postoperative time of getting out of bed and hospital stay were (58.20±5.54) min,(2.40±0.57) d and (3.80±0.61) d in UBE group,and (62.90±7.14) min,(4.40±0.64) d and (4.40±0.64) d in small fenestrum group,respectively;and had statistically difference between two groups(P<0.05). Postoperative VAS of low back and leg pain and ODI in both groups were significantly lower than those before surgery (P<0.05). VAS of lumbar pain in UBE group (1.37±0.49) score was lower than that of small fenestration group (2.45±0.64) score,and had statistically difference (t=9.745,P<0.05). Postoperative ODI in UBE group at 1 and 3 months were (28.54±3.31) % and (22.87±3.23) %,respectively,which were lower than those in small fenestra group (36.31±9.08) % and (29.90±8.36) %,and the difference was statistically significant (P<0.05). There were no significant difference in VAS and ODI between two groups at other time points (P>0.05). According to the modified MacNab evaluation criteria at the latest follow-up,49 patients got excellent result,3 good,and 2 fair in UBE group. In small fenestration group,35 patients got excellent,12 good,and 4 fair. In UBE group,amount of bone resection on L4,5 segment was (0.45±0.08) cm3 and (0.31±0.08) cm3 on the segment of L5S1. In small fenestration group,amount of bone resection on L4,5 segment was (0.57±0.07) cm3 and (0.49±0.04) cm3 on the segment of L5S1,and amount of bone resection of lower articular process laminar complex on the same segment in UBE group was less than that in small fenestration group (P<0.05). In UBE group,retention rate of laminoid complex on L4,5 segment was (0.73±0.04) and L5S1 segment was (0.83±0.03),while L4,5 segment was(0.68±0.06) and L5S1 segment was (0.74±0.04) in small fenestration group,the lower articular process laminar complex retention rate in UBE group was higher than that in small fenestration group(P<0.05). CONCLUSION: Both unilateral double-channel endoscopy and small fenestration of laminae could achieve good clinical results in treating LDH,but UBE has advantages of less trauma,higher efficiency,faster postoperative recovery and less damage to bone structure.

RESUMO

OBJECTIVE: To compare clinical efficacy and complication rate of percutaneous endoscopic transforaminal discectomy(PETD),percutaneous endoscopic interlaminar discectomy (PEID) and unilateral biportal endoscopic (UBE) in treating single-segment lumbar disc herniation(LDH). METHODS: From October 2019 to August 2021,121 LDH patients with single-segment treated by spinal endoscopy were retrospectively analyzed and divided into three groups. In PETD group,there were 48 patients,including 19 males and 29 females,aged from 18 to 72 years old with an average of (44.0±13.9) years old;3 patients with L3,4 segments,27 patients with L4,5 segments,and 18 patients with L5S1 segments. In PEID group,there were 43 patients,including 23 males and 20 females,aged from 20 to 69 years old with an average of (40.1±12.1) years old;1 patient with L3,4 segments,15 patients with L4,5 segments,and 27 patients with L5S1 segments. In UBE group,there were 30 patients,including 12 males and 18 females,aged from 29 to 72 years old with an average of (41.2±15.0) years old;1 patient with L3,4 segments,18 patients with L4,5 segments,and 11 patients with L5S1 segments. Operation time,blood loss,fluoroscopy times and complications among three groups were observed and compared. Before opertaion,3 months after operation and at the latest follow-up,visual analogue scale (VAS) was used to evaluate low back pain and lower extremity pain,Oswestry disfunction index (ODI) was used to evaluate lumbar function,and modified MacNab was used to evaluate clinical efficacy at the latest follow-up. RESULTS: All patients were performed endoscopic spinal surgery completly and were followed up for at least 12 months. One patient occurred dural sac rupture both in PETD and PEID group,and dural sac rupture was small,and there was no obvious discomfort after operation. Two patients were occurred intraoperative rupture of dural sac in UBE group. One patient was occurred cerebrospinal fluid leakage after operation,and was improved after rest in supine position and fluid rehydration. One patient without no significant postoperative discomfort. (1)There were no significant difference in operating time,blood loss and hospital stay between PETD and PEID group (P>0.05),while UBE group was higher than those of PETD and PEID group (P<0.05). There was no statistical significance in fluoroscopy times between PEID and UBE group (P>0.05),but PETD group was higher than that of PEID and UBE group (P<0.05). (2)VAS of low back pain at 3 months after operation in UBE group was higher than that in PETD and PEID group (P<0.05),but there was no significant difference between PETD and PEID group (P>0.05). At the latest follow-up,there was no significant difference in VAS of low back pain among three groups (P>0.05). (3)Lower extremity pain of VAS and ODI among 3 groups after operation were significantly improved at all time points compared with those before opertaion(P<0.05),and there were no statistical significance between groups (P>0.05),and there were no statistical significance in interaction between different time points and operation groups (P>0.05). (4) At the latest follow-up,according to the modified MacNab standard,the results of PETD group were excellent in 27 patients,good in 16 patients,moderate in 4 patients,poor in 1 patient;in PEID group,27 patients got excellent result,12 good,3 moderate,and 1 poor;in UBE group,16 patients got excellent,10 good,2 moderate,and 2 poor. There was no significant difference among three groups (χ2=0.308,P>0.05). Recurrence of lumbar disc herniation occurred in 1 patient among each three groups,symptoms were improved in 2 patients after symptomatic treatment,and 1 patient was treated in other hospitals. CONCLUSION: PETD,PEID and UBE techniques could achieve good early clinical effects in treating lumbar disc herniation with similar complication rates. Both of PETD and PEID are single-channel minimally invasive surgery,with mild intraoperative tissue damage and quick postoperative recovery; while intraoperative fluoroscopy of PETD was relatively more frequent, and PEID was more suitable for L5S1 segment;UBE is a two-channel surgery,in which the intraoperative soft tissue damage is more severe,but exposure is broad,which is more suitable for complex cases.

RESUMO

OBJECTIVE: To explore clinical effect of different intervertebral fusion devices (cage) in treating postoperative recurrent lumbar disc herniation (LDH). METHODS: One hundred and forty-two LDH patients with recurrence after simple intervertebral disc nucleus pulpoideectomy from January 2019 to January 2021 were retrospectively analyzed. All patients were treated with combined underchannel fixation and interbody fusion and divided into a single anatomical group,two-anatomical group and a single banana group according to types and numbers of implanted cage. There were 51 patients in a single anatomical group,included 29 males and 22 females,aged from 39 to 65 years old with an average of (53.74±5.68) years old;body mass index (BMI) ranged from 18.62 to 28.13 kg·m-2 with an average of (22.08±2.15) kg·m-2;the interval between operation and recurrence ranged from 0.5 to 4.0 years with an average of (2.7±0.8) years;5 patients with L3,4,35 patients with L4,5 and 11 patients with L5S1;a single anatomical cage was implanted. There were 46 patients in two-anatomical group,included 25 males and 21 females,aged from 37 to 66 years old with an average of (54.52±6.02) years old;BMI ranged from 18.25 to 28.44 kg·m-2 with an average of (21.74±1.83) kg·m-2;the interval between operation and recurrence ranged from 0.5 to 5.0 years with an average of (2.7±0.9) years;4 patients with L3,4,32 patients with L4,5 and 10 patients with L5S1;two-anatomical cages were implanted. There were 45 patients in a single banana group,included 22 males and 23 females,aged from 38 to 65 years old with an average of (54.49±6.45) years old;BMI ranged from 18.85 to 28.20 kg·m-2 with an average of (21.63±1.59) kg·m-2;the interval between operation and recurrence ranged from 0.5 to 5.0 years with an average of (2.6±1.0) years;3 patients with L3,4,36 patients with L4,5 and 16 patients with L5S1;a single banana cage was implanted. Operation time,intraoperative blood loss,incision length,postoperative incision drainage volume,hospital stay and complications among 3 groups were observed and compared. The height of intervertebral space before and after operation,curvature of lordosis and the postoperative intervertebral fusion were compared. Visual analogue scale (VAS) and Oswestry disability index (ODI) were used to evaluate degree of lumbar pain and lumbar function before operation,1 and 6 months after operation,respectively. RESULTS: All patients among 3 groups were followed up at least 6 months,and no cases were fell out. There were no significant difference in operation time,intraoperative blood loss,incision length,postoperative incision drainage volume and hospital stay among 3 groups (P>0.05). At 6 months after operation,the height of intervertebral space in two-anatomical group and a single group were [(11.08±1.78) mm,(10.95±1.62) mm],curvature of lordosis were [(12.05±1.86) °,(11.63±1.57) °],which were higher than those in a single dissection group (10.14±1.54) mm,(10.92±1.45) °,and the difference were statistically significant (P<0.05). The interbody fusion rate between two-anatomical and a banana group (95.65%,95.56%) were higher than that in a single anatomical group (78.43%) at 6 months after operation (P<0.05). VAS and ODI of lumbar among 3 groups were decreased at 1 and 6 months after operation (P<0.05). There was no significant difference in complications among 3 groups (P>0.05). CONCLUSION: The three fusion devices could achieve significant results in treating postoperative recurrence of LDH,but the implantation of two-anatomical cage and a single banana cage are more helpful to maintain the height of intervertebral space and lordosis curvature of patients with postoperative recurrence of LDH,and obtain good intervertebral fusion results.

RESUMO

The Transforaminal Endoscopic Surgical System (TESSYS) technique has gained popularity for the treatment of lumbar disc herniations. Foraminoplasty is the key procedure in TESSYS. However, it requires advanced skills and long-term learning, which hinder its widespread adoption among surgeons. Recently, the introduction of full-endoscopic solutions has made the process more manageable. The main difference from traditional single-portal endoscopic surgery is that full-endoscopic surgery is equipped with a larger working channel, allowing full visualization of foraminoplasty and decreasing reliance on intraoperative fluoroscopy. Recently, published studies have shown that full-endoscopic foraminoplasty and lumbar discectomy (FEFLD) could achieve comparable results to conventional microdiscectomy in terms of pain relief and functional outcomes, while enhancing postoperative recovery. This study describes the technique of FEFLD in detail, including every crucial step, such as patient positioning, puncture trajectory, endoscopic dissection of the superior articular process (SAP), endoscopic foraminoplasty, and more. We hope this will be helpful to beginners who wish to apply this approach.

RESUMO

PURPOSE: A transthoracic anterior or lateral approach for giant thoracic disc herniations is a complex operation which requires optimal exposure and maximal visualisation. Traditional metal rigid retractors may inflict significant skin trauma especially with prolonged operative use and limit the working angles of endoscopic instrumentation at depth. We pioneer the use of the Alexis retractor in transthoracic thoracoscopically assisted discectomy for the first time. METHODS: The authors describe and demonstrate the technical use of the Alexis retractor during operative cases. Patient positioning, clinical rationale and operative nuances are elucidated for readers to gain an appreciation of the transthoracic approach to thoracic disc herniations. RESULTS: The advantages of the Alexis retractor include minimally invasive circumferential flexible retraction, facilitation of bimanual instrument use, diminished risk of surgical site infections and reduced rib retraction leading to less postoperative pain. CONCLUSION: Use of the flexible and intuitive Alexis retractor maximises operative exposure and is an effective adjunct when performing complex transthoracic approaches for thoracic disc herniations.

RESUMO

BACKGROUND: Lumbar disc herniation is a common spinal disease that causes low back pain; surgery is required when conservative treatment is ineffective. There is a growing demand for minimally invasive surgery in younger patient populations due to their fear of significant damage and a long recovery period following standard open discectomy. The development history of minimally invasive surgery is relatively short, and no gold standard has been established. OBJECTIVES: We aimed to find, via a network meta-analysis, the best treatment for low back pain in younger patient populations. STUDY DESIGN: Network meta-analysis. METHODS: The PubMed, Embase, Cochrane Library, and Web of Science databases were searched. Data quality was evaluated using RevMan 5.3 (The Nordic Cochrane Centre for The Cochrane Collaboration), while STATA 14.0 (StataCorp LLC) was used for the network meta-analysis and to merge data on the Visual Analog Scale (VAS) score, Oswestry Disability Index (ODI) score, complication, blood loss, reoperation rate, and function score. RESULTS: We included 50 randomized controlled trials, involving 7 interventions; heterogeneity and inconsistency were acceptable. Comparatively, microendoscopic discectomy and percutaneous endoscopic lumbar discectomy were the best surgical procedures from the aspects of VAS score and ODI score, while standard open discectomy was the worst one from the aspect of ODI score. Regarding complications, tubular discectomy was preferred with the fewest complications. Additionally, microendoscopic discectomy outperformed other surgical procedures in reducing blood loss and reoperation rate. LIMITATIONS: First, follow-up data were not reported in all included studies, and the follow-up time varied from several months to 8 years, which affected the results accuracy of our study to some extent. Second, there were some nonsurgical factors that also affected the self-reported outcomes, such as rehabilitation and pain management, which also brought a certain bias in our study results. CONCLUSIONS: Compared to standard open discectomy, minimally invasive surgical procedures not only achieve satisfactory efficacy, but also microendoscopic discectomy and percutaneous endoscopic lumbar discectomy can obtain a more satisfactory short-term VAS score and ODI score. Microendoscopic discectomy has significant advantages in blood loss and reoperation rate, and tubular discectomy has fewer postoperative complications.

RESUMO

OBJECTIVE: This study aims to compare the effects of microscopic microdiscectomy and microendoscopic discectomy on pain, disability, fear of falling, kinesiophobia, anxiety, quality of life in patients with lumbar disc herniation (LDH). METHODS: A total of 90 patients who underwent microscopic microdiscectomy (n = 40) and microendoscopic discectomy (n = 50) for LDH were included in this study. The patients' pain, disability, fear of falling, kinesiophobia, anxiety, and quality of life were evaluated before the surgery, in the early postoperative period and three months after. RESULTS: In patients who underwent microendoscopic discectomy, the results of pain, disability, fear of falling, kinesiophobia and anxiety were statistically decreased compared with the microscopic microdiscectomy in the early postoperative period and three months later (p < 0.05). Also, a statistically higher increase was observed in the general health perception of patients who underwent microendoscopic discectomy three months after the operation (p < 0.01). CONCLUSION: Microendoscopic microdiscectomy, remains the most effective and widely applied method with advantages on pain, quality of life, and improved physical functions.


OBJETIVO: Este estudio tiene como objetivo comparar los efectos de la microdiscectomía microscópica y la discectomía microendoscópica sobre el dolor, la discapacidad, el miedo a caer, la kinesiofobia, la ansiedad y la calidad de vida en pacientes con hernia de disco lumbar (LDH). MÉTODOS: Se incluyeron en este estudio un total de 90 pacientes sometidos a microdiscectomía microscópica (n = 40) y discectomía microendoscópica (n = 50) por LDH. Se evaluó el dolor, la discapacidad, el miedo a caer, la kinesiofobia, la ansiedad y la calidad de vida de los pacientes antes de la cirugía, en el postoperatorio temprano y tres meses después. RESULTADOS: En los pacientes sometidos a discectomía microendoscópica, los resultados de dolor, discapacidad, miedo a caer, kinesiofobia y ansiedad disminuyeron estadísticamente en comparación con la microdiscectomía microscópica en el postoperatorio temprano y tres meses después (p < 0.05). Además, se observó un aumento estadísticamente mayor en la percepción de salud general de los pacientes sometidos a discectomía microendoscópica tres meses después de la operación (p < 0.01). CONCLUSIÓN: La microdiscectomía microendoscópica sigue siendo el método más eficaz y ampliamente aplicado con ventajas sobre el dolor, la calidad de vida y la mejora de las funciones físicas.

RESUMO

PURPOSE: To evaluate patient demographics, surgery characteristics, and patient-reported clinical outcomes related to the implementation of lumbar PTED in Denmark by surgeons novice to the PTED technique. METHODS: All adult patients treated with a lumbar PTED from our first surgery in October 2020 to December 2021 were included. Data was generated by journal audit and telephone interview. RESULTS: A total of 172 adult patients underwent lumbar PTED. Surgery duration was a median of 45.0 (35.0-60.0) minutes and patients were discharged a median of 0 (0-1.0) days after. Per operatively one procedure was converted to open microdiscectomy due to profuse bleeding. Post operatively one patient complained of persistent headache (suggestive of a dural tear), two patients developed new L5 paresthesia, and three patients had a newly developed dorsal flexion paresis (suggestive of a root lesion). Sixteen patients did not complete follow-up and 24 (14.0%) underwent reoperation of which 54.2% were due to residual disk material. Among the remaining 132 patients, lower back and leg pain decreased from 7.0 (5.0-8.5) to 2.5 (1.0-4.5) and from 8.0 (6.0-9.1) to 2.0 (0-3.6) at follow-up, respectively (p < 0.001). Additionally, 93.4% returned to work and 78.8% used less analgesics. Post hoc analysis comparing the early half of cases with the latter half did not find any significant change in surgery time, complication and reoperation rates, nor in pain relief, return to work, or analgesia use. CONCLUSION: Clinical improvements after lumbar PTED performed by surgeons novel to the technique are satisfactory, although the reoperation rate is high, severe complications may occur, and the learning curve can be longer than expected.
