Surgical management of lower limb radiculopathy following acute singe-level osteoporotic vertebral fracture of lower lumbar spine in geriatric patient: a retrospective study

BackgroundRadiculopathy of the lower limb after acute osteoporotic vertebral fractures (OVFs) in the lower lumbar spine is uncommon in geriatric patients. Moreover, surgical intervention is generally recommended in patients who are irresponsive to conservative treatment. Determining an optimum surgical strategy is challenging considering the poor general condition of this population. Thus, herein, we established an algorithm for surgically managing this clinical scenario, hoping to provide a reference for making a surgical decision.MethodsWe retrospectively studied patients who suffered from new-onset radiculopathy of the lower limb after acute single-level OVFs in the lower lumbar spine and eventually underwent surgical intervention at our department. Information on the demographics, bone quality, AO spine classification of the vertebral fracture, pre-existing degenerative changes, including foraminal stenosis and lumbar disc herniation, and surgical intervention type was collected. Additionally, clinical outcomes, including preoperative and postoperative visual analog scale (VAS) scores for back and leg pain, Oswestry disability index (ODI), and MacNab criterion for response to surgery, were evaluated.ResultsFrom September 2019 to December 2021, a total of 22 patients with a mean age of 68.59 ± 9.74 years were analyzed. The most involved vertebra was L5 (54.5%), followed by L4 (27.3%) and L3 (18.2%). Among the 22 patients, 15 (68.2%) were diagnosed with the A1 type fracture of AO classification, and among them, 11 (73.3%) were characterized by the collapse of the inferior end plate (IEP). Three patients (13.6%) suffered from A2-type fractures, whereas four patients (18.2%) suffered from A3-type fractures. Pre-existing degenerative changes were observed in 12 patients (54.5%) of the patients. A total of 16 patients (72.7%) were treated by percutaneous kyphoplasty (PKP). Additionally, three patients underwent posterior instrumentation and fusion, two patients underwent a secondary endoscopic foraminoplasty, and one patient underwent a secondary radiofrequency ablation. The mean follow-up period was 17.42 ± 9.62 months. The mean VAS scores for leg and back pain and ODI decreased significantly after the surgery (P < 0.05). The total satisfaction rate at the last follow-up was 90.9% per the Macnab criterion.ConclusionPatients with OVFs in the IEP are predisposed to suffer from radiculopathy of the lower limb. PKP alone or in combination with other minimally invasive surgical strategies is safe and effective in treating stable fractures. Additionally, aggressive surgical intervention should be considered in patients with unstable fractures or severe foraminal encroachment.

Analgesic effects of pectoserratus plane block and intermediate cervical plexus block for transaxillary endoscopic thyroidectomy: a prospective randomized controlled trial.

Transaxillary endoscopic thyroidectomy (TAET) is favored for its favorable cosmetic outcomes and the preservation of anterior cervical function. Despite these benefits, postoperative analgesia has traditionally relied on pharmacological interventions, and regional anesthetic procedures may be an alternative method. This study aimed to evaluate the efficacy of an ultrasound-guided pectoserratus plane block (PSPB) combined with an intermediate cervical plexus block (ICPB) for TAET. Forty patients undergoing TAET were randomized into two groups: the nerve block group (N.=20) received ultrasound guided PSPB with 20 ml of 0.375% ropivacaine and ICPB with 8 mL of 0.3% ropivacaine, while the control group (N.=20) received no block. The primary outcome was the Visual Analog Scale (VAS) scores for postoperative neck and axillary pain at different time points (1, 6, 12, 24 h) during rest and movement post-TAET. The secondary outcomes included intraoperative remifentanil consumption, incidence of postoperative nausea and vomiting (PONV), number of remedial analgesic requirements, and patient satisfaction postoperatively. Compared to the control group, patients in the nerve block had significantly lower VAS scores of the neck and axilla whether at rest or movement, and 1, 6, 12, and 24 h postoperatively (P<0.0125). The nerve block group showed higher patient satisfaction (P<0.001). No difference was observed in intraoperative remifentanil consumption, need for rescue analgesics, or other adverse effects 48 h postoperatively. Ultrasound-guided PSPB with ICPB significantly alleviated postoperative pain and improved patient satisfaction with TAET.

473 Does Bioactive Glass Ceramic Cage Achieve Early Fusion in Anterior Cervical Discectomy and Fusion?: A Prospective Multicenter Study

INTRODUCTION: Bioactive glass ceramic (BGC) is known to chemically bond with bones by forming a hydroxyapatite layer and inducing osteoblastic differentiation. METHODS: A total of 40 patients who underwent 1-level ACDF using BGC cage to treat degenerative cervical radiculopathy/myelopathy were enrolled in multicenter (3 hospitals) prospectively. Fusion defined by CT and X-ray, subsidence, and breakage of BGC cage were evaluated at postoperative six months period. Demographic data, fusion rates, visual analog scale (VAS) scores for neck or arm pain, Neck Disability Index (NDI) scores, SF-36 and complications were also checked. RESULTS: Fusion rates were 88.5% when assessed by interspinous motion and 92.3% when CT assessed by intragraft and extragraft bone bridging in the BGC group at 6-month follow-up. The neck pain or arm pain VAS scores, NDI scores and SF-36 significantly improved. No material-related complications were observed related BGC cage, such as graft resorption and breakage. Subsidence occurred 3 patients who improved neck pain or arm pain VAS scores, and NDI scores compared to preoperative status. CONCLUSIONS: BGC cage was effective and safe when used in ACDF, conferring a early and high fusion rate and favorable clinical outcomes at postoperative 6 months period.

Preoperative Hounsfield Units Predict Pedicle Screw Loosening in Osteoporotic Patients Following Short Segment Lumbar Fusion.

Retrospective Cohort. (1) To determine if vertebral HU values obtained from preoperative CT predict postoperative outcomes following 1-3 level lumbar fusion and (2) to investigate whether decreased BMD values determined by HU predict cage subsidence and screw loosening. In light of suboptimal screening for osteoporosis, vertebral computerized tomography(CT) Hounsfield Units(HU), have been investigated as a surrogate for bone mineral density(BMD). In this retrospective study, adult patients who underwent 1-3 level posterior lumbar decompression and fusion(PLDF) or transforaminal lumbar interbody and fusion(TLIF) for degenerative disease between the years 2017-2022 were eligible for inclusion. Demographics and surgical characteristics were collected. Outcomes assessed included 90-day readmissions, 90-day complications, revisions, patient reported outcomes(PROMs), cage subsidence, and screw loosening. Osteoporosis was defined as HU of ≤110 on preoperative CT at L1. We assessed 119 patients with a mean age of 59.1, of whom 80.7% were white and 64.7% were nonsmokers. The majority underwent PLDF(63%) compared to TLIF(37%), with an average of 1.63 levels fused. Osteoporosis was diagnosed in 37.8% of the cohort with a mean HU in the osteoporotic group of 88.4 compared to 169 in non-osteoporotic patients. Although older in age, osteoporotic individuals did not exhibit increased 90-day readmissions, complications, or revisions compared to non-osteoporotic patients. A significant increase in the incidence of screw loosening was noted in the osteoporotic group with no differences observed in subsidence rates. On multivariable linear regression osteoporosis was independently associated with less improvement in visual analog scale(VAS) scores for back pain. Osteoporosis predicts screw loosening and increased back pain. Clinicians should be advised of the importance of preoperative BMD optimization as part of their surgical planning and the utility of vertebral CT HU as a tool for risk stratification. 3.

Factors associated with increased length of stay in degenerative cervical spine surgery: a cohort analysis from the Canadian Spine Outcomes and Research Network.

Postoperative length of stay (LOS) significantly contributes to healthcare costs and resource utilization. The primary goal of this study was to identify patient, clinical, surgical, and institutional variables that influence LOS after elective surgery for degenerative conditions of the cervical spine. The secondary objectives were to examine the variability in LOS and institutional practices used to decrease LOS. This was a multicenter observational retrospective cohort study of patients enrolled in the Canadian Spine Outcomes and Research Network (CSORN) between January 2015 and October 2020 who underwent elective anterior cervical discectomy and fusion (ACDF) (1-3 levels) or posterior cervical fusion (PCF) (between C2 and T2) with/without decompression for degenerative conditions of the cervical spine. Prolonged LOS was defined as LOS greater than the median for the ACDF and PCF populations. The principal investigators at each participating CSORN healthcare institution completed a survey to capture institutional practices implemented to reduce postoperative LOS. In total, 1228 patients were included (729 ACDF and 499 PCF patients). The median (IQR) LOS for ACDF and PCF were 1.0 (1.0) day and 5.0 (4.0) days, respectively. Predictors of prolonged LOS after ACDF were female sex, myelopathy diagnosis, lower baseline SF-12 mental component summary score, multilevel ACDF, and perioperative adverse events (AEs) (p < 0.05). Predictors of prolonged LOS after PCF were nonsmoking status, education less than high school, lower baseline numeric rating scale score for neck pain and EQ5D score, higher baseline Neck Disability Index score, and perioperative AEs (p < 0.05). Myelopathy did not significantly predict prolonged LOS within the PCF cohort after multivariate analysis. Of the 8 institutions (57.1%) with an enhanced recovery after surgery (ERAS) protocol or standardized protocol, only 3 reported using an ERAS protocol specific to patients undergoing ACDF or PCF. Patient and clinical factors predictive of prolonged LOS after ACDF and PCF are highly variable, warranting individual consideration for possible mitigation. Perioperative AEs remained a consistent independent predictor of prolonged LOS in both cohorts, highlighting the importance of preventing intra- and postoperative complications.

Perioperative analgesic management in patients with bladder exstrophy: A clinical study

Background: Bladder exstrophy is a complex, rare congenital malformation with an incidence of 3.3 cases in every 100000 live births and is slightly more common in males. Primary surgical repair requires many hours of surgery with fluid and blood loss. Because of wide fluctuations in hemodynamics, a longer duration of surgery, smaller age, risk of hypothermia and post-operative intensive care may be required. We evaluated the use of continuous caudal epidural infusion of bupivacaine and fentanyl under general anesthesia for urinary bladder exstrophy-epispadias surgery in children. Aims and Objectives: Aim of the study was to evaluate the postoperative analgesia in patients undergoing surgery for bladder exstrophy. The primary objective was to assess the postoperative pain using FLACC scale and sedation score after successful caudal administration. Secondary objective was to assess the hemodynamic changes after caudal administration. Materials and Methods: A total of 13 patients aged between 9months and 13 years of either sex, weighing between 5kg to 30kg, belonging to ASA grade II to IV, underwent surgery for epispadias–exstrophy complex. Initial bolus 0.75ml/kg of 0.25% bupivacaine with fentanyl 1ug/kg was given through epidural. Postoperative analgesia was maintained by continuous infusion of 0.0625% bupivacaine @0.1ml/kg/hr in young children and 0.125% bupivacaine with fentanyl 1ug/ml in older children for 4-5 days with the help of ON-Q pump or infusion pump. Baseline hemodynamic parameters including MAP, heart rate and SpO2 was recorded at various time intervals. Postoperative pain was assessed using face, legs, activity, cry and consolability (FLACC) pain scale and sedation score was assessed by using ramsay sedation score. Results: There was a statistically significant decrease in mean pulse rate in the study group from baseline to thirty minutes after reversal (p&lt;0.001). Similar observation was made for mean arterial pressure which also showed statistically significant decrease from baseline to thirty minutes after reversal (p&lt;0.001). No change was observed in SpO2 from baseline to any other follow-up interval. Conclusion: Perioperative anesthetic and analgesic management of the bladder exstrophy patient can improve the success rate. Epidural bupivacaine with or without fentanyl infusions for short duration can provide safe analgesia.

Sedation for Colonoscopy Procedures Using Dexmedetomidine Versus Propofol-Fentanyl Infusions: A Prospective Randomized Controlled Trial.

Different anaesthetists for sedation or monitored anaesthesia care have been used for colonoscopy. The target of this research was the ability to perform colonoscopy under a painless degree of sedation and the prevalence of undesired proceedings. A total of 60 patients were randomly divided into two groups: Group D received dexmedetomidine and Group PF received propofol-fentanyl. Patients in both groups received the same infusion ratio. The minimum infusion amount of dexmetatomidine is (0.1 to 0.4 μg kg-1 h-1) in Group D, whereas fentanyl is administered at a rate of 0.01 to 0.05 μg kg-1 min-1 in the PF group during the approximately 45-min colonoscopy. Group D exhibited significantly lower modified Observer's Assessment of Alertness/Sedation (OAA/S) scores at intraoperative time points T1-T12. Group D also exhibited significantly lower visual analog scale scores for pain at intraoperative time points T4 and T7. The mean arterial pressure was significantly lower in Group D at intraoperative times T6-T8 and T11-T12, as well as upon admission to the post-anaesthesia care unit (PACU) and 30 min after admission to the PACU. The results of the ANOVA tests revealed a significantly lower heart rate in Group D. The respiratory rate exhibited a notable decrease during time intervals T8 and T10 in the PF group. The administration of dexmetatomidine and propofol-fentanyl during colonoscopy was found to be safe. In addition, dexmetatomidine may present significant benefits in this context because of its lower occurrence of adverse respiratory events.

Comparison of the Efficacy of Zoledronate and Denosumab in Patients with Acute Osteoporotic Vertebral Compression Fractures: A Randomized Controlled Trial.

Background: The comparison of the efficacy of zoledronate and denosumab for treating osteoporosis is controversial, and few randomized controlled trials have compared these two drugs in practical patients with acute osteoporotic vertebral compression fractures (OVCFs). We conducted a randomized controlled study to compare the efficacy of zoledronate and denosumab in patients with acute OVCF, with a focus on the occurrence of new OVCF. Methods: We enrolled 206 subjects who had their first acute OVCF, without any previous history of osteoporosis medication. The patients were randomly assigned to receive either intravenous zoledronate once a year or subcutaneous denosumab twice a year. We investigated the OVCF recurrence, clinical outcome, bone mineral density (BMD), and bone turnover markers over 12 months. Results: The final cohort comprised 89 participants (mean age of 75.82 ± 9.34 years, including 74 women [83.15%]) in the zoledronate group and 86 patients (mean age of 75.53 ± 10.23 years, including 71 women [82.56%]) in the denosumab group. New OVCFs occurred in 8 patients (8.89%) in the zoledronate group and 11 patients (12.79%) in the denosumab group (odds ratio, 1.485 [95% confidence interval, 0.567-3.891], p = 0.419). No significant difference was observed in the survival analysis between the two groups (p = 0.407). The clinical outcome, including the visual analog scale score for pain and simple radiographic findings, did not differ between the two groups. The changes in BMD and bone turnover markers were also not significantly different between the two groups. Additionally, drug-related adverse events did not differ between the groups in terms of safety. Conclusions: The efficacy of zoledronate was comparable to that of denosumab in terms of the occurrence of new OVCFs, as well as of the overall clinical course in patients with their first acute OVCF. Notably, this study represents the first comparison of these two drugs in patients with acute OVCF. However, further research with large-scale and long-term follow-up is necessary.

Transcatheter arterial tendinopathy embolization as a treatment for painful and refractory tendinopathy: a systematic review and meta-analysis.

Transcatheter arterial embolization (TAE) is a novel minimally invasive therapy for painful tendinopathy in patients with pain refractory to conservative management. The purpose of this study was to evaluate evidence on the efficacy of TAE for tendinopathy related pain. Using Embase, PubMed, and Web of Science, a systematic review and meta-analysis was performed to identify studies evaluating TAE for painful tendinopathy. The primary outcome measure was change in pain scale score at 6months. A Ratio of Means (ROM) was used to compare the effect size post treatment as compared to baseline. The Visual Analog Scale (VAS) was used as the metric for comparison. After screening titles, abstracts, and the full text, 5 studies met inclusion criteria. A total of 97 tendinopathy embolization procedures performed in 74 patients were included. Patients who underwent TAE demonstrated declines in VAS ROM at 1day 0.53 [95% CI 0.31,0.88], 1week (0.51 [95% CI 0.32,0.79]), 1month (0.45 [95% CI 0.29, 0.71]), 3-4months (0.33 [95% CI 0.22,0.48]), and 6months following embolization (0.18[95% CI 0.13,0.26]), respectively. TAE provides substantial short-term reductions in pain scores for patients suffering with refractory tendinopathy related pain of the rotator cuff, elbow extensor and flexor, Achilles, and patellar tendons.

Psychological Factors Can Affect the Clinical Outcome of Chemonucleolysis with Condoliase in Patients with Lumbar Disk Herniation.

Condoliase-based chemonucleolysis is a minimally invasive intermediate treatment option between conservative approaches and surgical interventions for lumbar disk herniation (LDH). In this study, the effects of psychological factors on the clinical outcomes of condoliase therapy for LDH were assessed. This study involved patients with LDH who received condoliase injections over a 1-year follow-up period. Data from the visual analog scale (VAS) scores for leg and back pain, Oswestry Disability Index, and Hospital Anxiety and Depression Scale (HADS), which was utilized for the psychological assessment, were collected. Using magnetic resonance imaging, changes in disk height and degeneration were evaluated. Data were assessed at baseline and 1-month, 3-month, and 1-year follow-ups. Condoliase therapy was considered effective in patients whose VAS score for leg pain improved by ≥50% at 1 year from baseline and who did not require surgery. The patients were divided into two groups: those who reported effective treatment (Group E) and those who did not (Group I). Between these two groups, comparative analyses were carried out. In this study, a total of 102 patients (70 men; mean age, 43.8±18.2 years) were included. Condoliase therapy was effective in 76 patients (74.5%). Thirty-five patients (34.3%) showed psychological factors (HADS-Anxiety [HADS-A]≥8 or HADS-Depression [HADS-D]≥8) preoperatively and had a significantly lower rate of effectiveness than did those without psychological factors. Group I demonstrated significantly higher baseline back pain VAS, HADS, and HADS-D scores when compared with Group E. Logistic regression analysis identified females and the baseline HADS-D score as independent factors that were related to the effectiveness of condoliase therapy. The patients with psychological factors tended to experience residual pain resulting in adverse effects on the clinical outcomes of chemonucleolysis with condoliase.

Comparison of the Medium-term Outcomes of Anterior Lumbar Discectomy and Fusion with Minimally Invasive Transforaminal Lumbar Interbody Fusion: A Retrospective Cohort Study.

Lumbar degenerative diseases (LDDs) with huge herniation in the left lateral recess or central canal present challenges for oblique lateral lumbar interbody fusion (OLIF) or endoscope-assisted OLIF procedures. Currently, minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) is the primary approach for this issue. This study aims to provide a standardized technical description of the anterior lumbar discectomy and fusion (ALDF) and evaluate the medium-term clinical effectiveness of both ALDF and MIS-TLIF techniques. A retrospective review was performed on LDDs who underwent ALDF and MIS-TLIF surgery from January 2018 to January 2020. The evaluation encompassed various clinical outcomes, such as the visual analogue scale (VAS) scores for back pain and leg pain (VAS-back, VAS-leg), the Oswestry disability index (ODI), the 36-item short-form health survey mental component summary (SF-36 MCS), and the physical component summary (SF-36 PCS). Additionally, radiological parameters, including disc height (DH), segmental disk angle (SDA), lumbar lordosis (LL), and cross-sectional area (CSA), were assessed. Data including radiculopathy, estimated blood loss, operation time, time of getting out of bed, fusion rate, and complications were recorded. Student's independent samples t test and Pearson's chi-square test were used to compare the differences between groups. In total, 47 patients were treated by ALDF and 48 patients were treated by MIS-TLIF. The ALDF group exhibited statistically significant lower estimated blood loss and earlier time of getting out of bed compared to the MIS-TLIF group (p < 0.05). The ALDF group demonstrated lower VAS-back scores and a higher remission rate of low back pain 3 years after the surgery (p < 0.05). During the entire follow-up period, the ALDF group exhibited higher increases in DH and SDA compared to the MIS-TLIF group (p < 0.05). At 6 months, the fusion rate in the ALDF group was significantly higher than in the MIS-TLIF group (p < 0.05). The comparison revealed no statistically significant differences in complication rates between the two groups (p > 0.05). The ALDF could be considered as a viable surgical alternative for the treatment of LDDs that necessitate ventral neural direct decompression. ALDF exhibited favorable medium-term outcomes in patients with LDDs, displaying advantages in facilitating expedited recovery, enhancing radiographic outcomes, and elevating the remission rate of low back pain. Although ALDF presents slightly higher complication rates compared to MIS-TLIF, it does not adversely affect clinical outcomes.

Efficacy of chronic neck pain self-treatment using press needles: a randomized controlled clinical trial.

Chronic neck pain is common among Japanese individuals, but few receive treatment. This randomized controlled trial aimed to evaluate the efficacy of acupuncture using press needles in the self-treatment of chronic neck pain and preliminarily identify the characteristics of patients likely to benefit from this treatment. Fifty participants with chronic neck pain were allocated to receive either press needle or placebo treatment for 3 weeks. The visual analogue scale (VAS) and motion-related VAS (M-VAS) scores for neck pain, Neck Disability Index score, and pressure pain threshold were measured at baseline, after the first session, at the end of the last session, and 1 week after the last session. Changes in the outcomes were analyzed using analysis of variance, and the relationships between the variables were evaluated using structural equation modeling. Intervention results as assessed by VAS score revealed no significant differences in the ANOVA. A between-groups comparison of M-VAS scores at the end of the last session and baseline showed a significant difference (press needle: -21.64 ± 4.47, placebo: -8.09 ± 3.81, p = 0.025, d = -0.65). Structural equation modeling revealed a significant pain-reducing effect of press needle treatment (β = -0.228, p = 0.049). Severity directly affected efficacy (β = -0.881, p < 0.001). Pain duration, baseline VAS and Neck Disability Index scores were variables explaining severity, while age and occupational computer use were factors affecting severity. Self-treatment with press needles for chronic neck pain did not significantly reduce the VAS score compared to placebo but reduced the motion-related pain as assessed by M-VAS score. A direct association was observed between pain severity and the effectiveness of press needles, and the impact of age and computer were indirectly linked by pain severity.

Efficacy of Biportal Endoscopic Decompression for Lumbar Spinal Stenosis: A Meta-Analysis With Single-Arm Analysis and Comparative Analysis With Microscopic Decompression and Uniportal Endoscopic Decompression.

Biportal endoscopic decompression is a minimally invasive surgical technique for lumbar spinal stenosis (LSS). This meta-analysis aimed to evaluate the efficacy and safety of biportal endoscopic decompression through both a single-arm analysis and a comparative analysis. A comprehensive literature search was conducted to identify eligible studies reporting the outcomes of biportal endoscopic decompression for LSS. Single-arm analysis and comparisons with microscopic and uniportal endoscopic decompression were performed. Evaluated outcomes included visual analog scale (VAS) scores for back pain and leg pain, Oswestry Disability Index (ODI) scores, operation time, estimated blood loss, duration of hospital stay, and adverse events. Single-arm analysis demonstrated significant improvements in VAS back pain, VAS leg pain, and ODI scores after biportal endoscopic decompression at postoperative 1-day to 36-month follow-up (all P < .001), compared with preoperative levels. The pooled mean single-level operation time was 71.44 min, and the pooled mean hospital stay was 3.63 days. The overall adverse event rate was 4.0%, with dural tear being the most common complication (3.0%). Compared with microscopic decompression, biportal endoscopic decompression showed significantly lower VAS back pain at 1-month ( P < .001) and 6-month ( P < .001) follow-up; lower VAS leg pain at 1-month ( P = .045) follow-up; lower ODI scores at 3-month ( P < .001), 12-month ( P = .017), and >12-month ( P = .007) follow-up; lower estimated blood loss ( P = .003); and shorter hospital stay ( P < .001). Adverse event rates did not differ between the techniques. No significant differences were observed between biportal endoscopic and uniportal endoscopic decompression groups for most efficacy and safety outcomes. Biportal endoscopic decompression emerges as a safe and effective alternative for LSS, presenting potential advantages over the microscopic technique and comparable efficacy with the uniportal endoscopic technique.

Clinical efficacy analysis of surgical treatment for spinal metastasis under the multidisciplinary team using the NOMS decision system combined with the revised Tokuhashi scoring system: a randomized controlled study

ObjectiveDespite advancements in spinal metastasis surgery techniques and the rapid development of multidisciplinary treatment models, we aimed to explore the clinical efficacy of spinal metastasis surgery performed by a combined NOMS decision system-utilizing multidisciplinary team and Revised Tokuhashi scoring system, compared with the Revised Tokuhashi scoring system.MethodsClinical data from 102 patients with spinal metastases who underwent surgery at three affiliated hospitals of Zunyi Medical University from December 2017 to June 2022 were analysed. The patients were randomly assigned to two groups: 52 patients in the treatment group involving the combined NOMS decision system-utilizing multidisciplinary team and Revised Tokuhashi scoring system (i.e., the combined group), and 50 patients in the treatment group involving the Revised Tokuhashi scoring system only (i.e., the revised TSS-only group). Moreover, there were no statistically significant differences in preoperative general data or indicators between the two groups. Intraoperative and postoperative complications, average hospital stay, mortality rate, and follow-up observation indicators, including the visual analogue scale (VAS) score for pain, Eastern Cooperative Oncology Group (ECOG) performance status, Karnofsky Performance Status (KPS) score, negative psychological assessment score (using the Self-Rating Anxiety Scale, [SAS]), and neurological function recovery score (Frankel functional classification) were compared between the two groups.ResultsAll 102 patients successfully completed surgery and were discharged. The follow-up period ranged from 12 to 24 months, with an average of (13.2 ± 2.4) months. The patients in the combined group experienced fewer complications such as surgical wound infections 3 patients(5.77%), intraoperative massive haemorrhage 2 patients(3.85%), cerebrospinal fluid leakage 2 patients(3.85%), deep vein thrombosis 4 patients(7.69%),and neurological damage 1 patient(1.92%), than patients in the revised TSS-only group (wound infections,11 patients(22%); intraoperative massive haemorrhage, 8 patients(16%);cerebrospinal fluid leakage,5 patients(10%);deep vein thrombosis,13 patients (26%); neurological damage,2 patients (4%). Significant differences were found between the two groups in terms of surgical wound infections, intraoperative massive haemorrhage, and deep vein thrombosis (P < 0.05). The average postoperative hospital stay in the combined group (7.94 ± 0.28 days) was significantly shorter than that in the revised TSS-only group (10.33 ± 0.30 days) (P < 0.05). Long-term follow-up (1 month, 3 months, 6 months, and 1 year postoperatively) revealed better clinical outcomes in the combined group than in the revised TSS-only group in terms of VAS scores, overall KPS%, neurological function status Frankel classification, ECOG performance status, and SAS scores.(P < 0.05).ConclusionA multidisciplinary team using the NOMS combined with the Revised Tokuhashi scoring system for spinal metastasis surgery showed better clinical efficacy than the sole use of the Revised Tokuhashi scoring system. This personalized, precise, and rational treatment significantly improves patient quality of life, shortens hospital stay, reduces intraoperative and postoperative complications, and lowers mortality rates.

Current Approaches, Significance and Prognostic Impact of Lumbar Ligament Flavum Preserving Surgeries

Objectives: The aim of this study is to evaluate the use of flavum-preserving surgeries in lumbar disc herniation surgery, compare their clinical outcomes with standard microdiscectomy techniques, and demonstrate the transflaval microdiscectomy technique.&#x0D; Material and Methods: Between 2020 and 2023, a total of 48 patients who underwent transflaval microdiscectomy and 48 patients who underwent standard microdiscectomy at a single center were included in the study. Epidemiologic characteristics of the groups were described, and preoperative and postoperative visual analoge scale scores for leg pain (LPVAS) and back pain (BPVAS) were retrospectively analyzed.&#x0D; Results: There is no significant difference between the groups in preoperative mean LPVAS scores (p=0,474) and there is no significant difference between the groups in postoperative mean LPVAS scores (p=0,598). There is no significant difference between the groups in preoperative mean BPVAS scores (p=0,608). However there is a significant difference between the groups in postoperative mean BPVAS scores (p

Arthroscopically Assisted Coracoclavicular (CC) Stabilization Using a Suture Button Device for Lateral Clavicle Fractures with CC Ligament Injury.

Background: Lateral clavicle fractures represent approximately 10-15% of all clavicle fractures. However, controversy exists regarding the optimal surgical treatment because of instability associated with the coracoclavicular (CC) ligament injury and a small lateral fragment. The purpose of this study was to evaluate the radiological and clinical outcomes of arthroscopically assisted CC stabilization using a suture button device for lateral clavicle fractures accompanied by CC ligament injury. Methods: A retrospective observational study involved six patients with modified Neer type IIB fractures, which were treated with the technique and followed for 12 months. Postoperative range of motion (ROM) and X-rays were evaluated every 3 months. Shoulder functional scores (University of California Los Angeles score, Japanese Orthopedics Association score) and visual analog scale (VAS) scores for pain (at rest, at night, and during motion) and for satisfaction were analyzed 12 months after surgery. Results: Early phase ROM recovery and excellent outcomes were achieved. All patients achieved bone union. Slight superior clavicle displacement and bone hole dilation occurred with no critical complications. Conclusions: Arthroscopically assisted CC stabilization with a suture button device for unstable lateral clavicle fractures can produce satisfactory radiological and clinical results.

Comparative study of percutaneous transfacet screw and pedicle screw in oblique lumbar interbody fusion for the treatment of single-level lumbar spinal stenosis

Objective: To conduct a comparative study of radiological and clinical outcomes between percutaneous transfacet screw (TFS) and pedicle screw (BPS) in oblique lateral lumbar interbody fusion (OLIF) for single-level lumbar spinal stenosis. Methods: A retrospective cohort study. Patients who underwent OLIF with TFS or BPS for the treatment of single-level lumbar spinal stenosis at Beijing Jishuitan Hospital from January 2019 to June 2022 were retrospectively analyzed. Radiological parameters and clinical indicators were compared between the two groups. Radiological parameters included preoperative, immediate postoperative (within 5 days), and 1-year postoperative measurements of disc height and segmental lordosis angle, as well as interbody fusion status at 1 year postoperatively. Clinical indicators included operative time, blood loss, length of hospital stay, complications, and Oswestry Disability Index (ODI), visual analogue scale (VAS) scores for back pain, and leg pain before and 1 year after surgery. Results: Four male and 10 female patients with an average age of (61.0±11.2) years underwent OLIF with TFS, while 9 male and 12 female patients underwent OLIF with BPS, with a mean age of (60.9±6.7) years. There was no statistically significant difference in preoperative disc height between the TFS and BPS groups (P>0.05). The immediate postoperative disc height was (12.9±2.1) mm and it was (10.4±1.7) mm at 1-year follow-up in the TFS group; in the BPS group, it was (12.9±2.1) mm immediately postoperatively and (11.9±2.1) mm at 1-year follow-up; there was statistically significant difference between the two groups at 1-year follow-up (P=0.037). The segmental lordosis angle showed no significant differences within each group or between the two groups at preoperative, immediate postoperative, or 1-year postoperative follow-up (all P>0.05). At 1-year postoperative follow-up, the fusion rates was 92.9%(13/14) in the TFS group and 95.2%(20/21) in the BPS group, with no statistically significant difference between the two groups (P>0.05). The TFS group had a significantly shorter operative time and less blood loss compared to the BPS group [(164.3±33.9) minutes vs (191.7±31.8) minutes and (74.3±46.9) ml vs (124.8±54.0) ml, respectively] (both P<0.05). Both groups showed significant improvement in ODI and VAS scores at 1 year postoperatively compared to those preoperatively, but with no statistically significant difference was found between the groups (both P>0.05). Conclusions: OLIF with TFS fixation can effectively restore disc height and alleviate back and leg pain in patients with single-level lumbar spinal stenosis. Compared to the OLIF with BPS procedure, OLIF with TFS has shorter operative time and less blood loss.

Serratus anterior plane block (posterior approach) versus erector spinae plane block in modified radical mastectomy; A randomized comparative trial

ABSTRACT Background Regional analgesia as Erector Spinae Plane Block (ESPB) and Serratus Anterior Plane Block (SAPB) were used successfully for the control of perioperative pain in females undergoing modified radical mastectomy (MRM). Methods The trial included 56 females aged between 20 and 60 years old who had undergone MRM and were allocated into two groups (28 patients in each), group (I) for SAPB (posterior approach) and group (II) for ESPB. Measurements included demographic data, hemodynamic change, oxygen saturation, pain intensity by the visual analogue scale (VAS), sensory loss including axillary coverage and shoulder pain, incidence of neuropathic pain, total analgesic requirements, patient satisfaction and complications. Results Demographic data, hemodynamic changes and oxygen saturation showed statistically insignificant differences. There were insignificant differences in the visual analogue scale (VAS) for pain at rest and on movement between the two groups on the first postoperative day (p-value >0.278 and 0.111 respectively). ESPB provided significantly more segmental sensory loss than SAPB (posterior approach) (p-value <0.031). We reported statistically insignificant differences in terms of total morphine consumption, the first request for analgesia and total local anaesthetic consumption (p-value = 0.408, 0.916 and 0.574 respectively), axillary sensory loss, inferior shoulder pain (p-value = 0.763), the incidence of neuropathic pain assessed by the Deuleur Neuropathique 4 (DN4) scale after one week and one month (p-value = 1.000 and 0.554 respectively), Neuropathic Pain Scale (NPS) score, and patient satisfaction (p-value = 0.887) between the two groups with no documented complications. Conclusion We concluded that SAPB (posterior approach) and ESPB are safe and effective analgesic modalities for MRM with insignificant differences except for the more blocked dermatomes in the ESPB group.

Arthroscopic Partial Meniscectomy in Patients With Kellgren-Lawrence Grade 3 Osteoarthritis Shows Clinically Meaningful Improvement in Outcomes

To evaluate patient-reported outcome measures (PROMs) following arthroscopic partial meniscectomy (APM) in patients with Kellgren-Lawrence (KL) grade 3 on preoperative knee radiographs and a symptomatic meniscal tear. This was a retrospective study design using prospectively collected data from a single institution. Patients were included if they had KL grade 3 osteoarthritis on preoperative radiographs of the knee and completed a trial of nonoperative treatment for at least 6 weeks prior to APM. Patients were excluded if they had inflammatory arthritis, incomplete preoperative and/or 1-year postoperative follow-up data, repeat knee arthroscopy, and concomitant ligamentous injury. Statistical analyses used PROMs, preoperatively and up to 2 years postoperatively, to assess improvement utilizing scales with previously established thresholds, including minimal clinically important difference (MCID) and substantial clinical benefit (SCB). Eighty-two patients met the eligibility criteria (49 women [60%], mean [SD] age, 53.1 [9.3] years). At the 1-year follow-up, most patients achieved MCID: 73% in Knee Injury and Osteoarthritis Outcome Score (KOOS) Pain, 66% in KOOS Symptoms, and 78% in KOOS Activities of Daily Living (ADL). These improvements were similar at the 2-year follow-up: 75%, 72%, and 79% in each subscale, respectively. SCB was also demonstrated 1 year postoperatively, with 56%, 73%, and 71% achieving SCB for the KOOS Pain, Symptoms, and ADL subscales, respectively. These results largely persisted at the 2-year follow-up. Visual analog scale scores for pain also improved at 1- and 2-year postoperative periods with mean improvements from baseline of 2.80 and 2.87 points, respectively. Marx Activity Score decreased on average from baseline to 1- and 2-year follow-up. At a minimum of 1-year follow-up, most patients with KL grade 3 and a meniscal tear achieved MCID and SCB in KOOS Pain, KOOS Symptoms, and KOOS ADL, indicating meaningful outcome improvement for these patients.

Long-Term Efficacy Following Intra-articular Injection of Carboxymethyl-chitosan, a New Product Class for Knee Osteoarthritis: Results from an Observational Study in Germany.

Evaluate the real-world efficacy of a single intra-articular injection of carboxymethyl-chitosan (CM-chitosan), a new product class for knee osteoarthritis (OA). This post-marketing study included adult patients with knee OA, who received a single injection of 60mg CM-chitosan (currently marketed as KioMedinevsone) according to the instructions for use. Follow-up was performed at weeks1, 12, 24, and 36. Efficacy was evaluated using a Visual Analog Scale (VAS) score for pain, the Knee injury and Osteoarthritis Outcome Score (KOOS), Patient's Global Assessment (PGA), and overall patient satisfaction. Forty-nine patients were included in the study. VAS pain score significantly decreased from a median of 49.0mm at baseline to 24.0mm at week1 and to 18mm at week36. Pain improvement was stable since at week36; 91.8% of patients confirmed pain reduction. All KOOS subscales (symptoms, pain, activities of daily living, sports and recreational activities, quality of life) improved significantly compared to baseline at all time points. KOOS pain improved progressively from a median of 58.3% at baseline (mean 56.2 ± 18.8%) to 86.1% (mean 74.1 ± 24%) at week36 compared to baseline. Overall, more than 70% of patients reported a condition gain (PGA), matching well with the more than 75% of patients being satisfied with the treatment. At 6months, 72.7% of the patients could be classified as responder according to the OMERACT-OARSI proposed set of responder criteria. CM-chitosan showed a rapid onset of pain relief after 1week and with a duration of 9months. In a real-world setting, treatment with CM-chitosan would appear to be a potentially effective option to reduce pain and improve physical function and global condition in patients with knee OA, opening new perspectives in patients who are considered as refractory to current symptomatic therapies and where the unmet need is high.
