Efficacy of Chemonucleolysis with Condoliase in Patients Aged under 20 Years.

Chemonucleolysis with condoliase is a minimally invasive treatment option for lumbar disk herniation (LDH). However, studies reporting the efficacy of condoliase in patients aged <20 years are scarce. Therefore, the present study aimed to evaluate the efficacy of condoliase therapy for LDH in the aforementioned population. Condoliase administration was determined based on adequate informed consent. The study enrolled 138 patients (mean age, 41.3±15.4 years) with LDH who received condoliase injections with a follow-up period of 1 year. The patients were divided into Group Y (age, <20 years) and Group A (age, 20-70 years). The clinical outcomes were visual analog scale (VAS) scores for leg and back pain and Oswestry Disability Index (ODI) values. Changes in disk height and degeneration were evaluated. These data were obtained at baseline and at the 3-month and 1-year follow-ups. Condoliase therapy was considered to be effective if it improved the VAS score for leg pain by ≥50% at 1 year from baseline and prevented surgery. Groups Y and A consisted of 15 and 123 patients, respectively. Condoliase therapy was effective in 9 patients (60.0%) in Group Y and 96 patients (78.0%) in Group A. The rates of Pfirrmann grade deterioration and recovery were substantially higher in Group Y than in Group A (83.3% vs. 45.8% and 50.0% vs. 16.3%, respectively). While the disk height reduction in Group Y was greater at 3 months, it recovered to the same level as that in Group A at 1 year. In Group Y, patients who did not respond to the treatment exhibited a considerably higher preoperative ODI (P<0.05). Chemonucleolysis with condoliase is considered to have limited efficacy in patients aged <20 years. Caution should be taken when managing cases showing lumbar instability or existing disability. While chemonucleolysis with condoliase is a less invasive treatment option for LDH, the administration should be decided upon with sufficient consent considering the potential limited efficacy and disk degeneration.

Return to Work Following Anterior Lumbar Interbody Fusion with Percutaneous Posterior Pedicle Fixation: A Retrospective Analysis from Two Academic Centers in Germany.

Objective: Return to work after spinal surgery is a crucial factor in the recovery process. It can contribute not only to physical rehabilitation but also to psychological well-being. This study aims to evaluate the rate of return to work following elective lumbar spine surgery and identify predictors that predict failure of return to work. Methods: Adult patients who underwent anterior lumbar interbody fusion at two medical centers were retrospectively identified. A standardized telephone interview was conducted for the final analysis to assess the clinical outcomes of these patients. Results: Out of a total of 159 patients, 104 were of working age at the time of the elective surgery. Data were missing for 35 patients, who were thus excluded from the analysis. All patients had a minimum follow-up period of one year. After surgery, 75% of the patients returned to work within a median time of 3 months. Quality of life, back pain, leg pain, and ODI scores, as well as self-reported satisfaction, were significantly better in patients who returned to work (p < 0.05). Tobacco use and previous musculoskeletal surgery were significant predictive factors of failure to return to work. None of the patients who were unemployed prior to surgery returned to work. Conclusions: Our study reveals that 75% of patients returned to work within three months after surgery. The most significant predictor of failure to return to work is being unemployed before surgery. Additionally, preoperative education about postoperative behavior and physical activity could potentially increase the rate.

Minimally invasive versus mini-open transforaminal lumbar interbody fusion in managing low-grade degenerative spondylolisthesis

Data backgroundBecause the traditional open-TLIF approach has several drawbacks, minimally invasive surgery (MIS) approaches for TLIF (MISTLIF) have been developed to speed up recovery after surgery and minimize pressure on the para-spinal muscles, necessitating a cost-utility analysis for comparison in healthcare reforms.Objectives and aim of the workThis study aimed to compare the radiological and clinical parameters between mini-open TLIF and minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) surgery in patients with single-level lumbar degenerative spondylolisthesis.HypothesisThis study hypothesizes that both minimally invasive and mini-open methods using sublaminar trimming laminoplasty (SLTL) (while preserving midline structures) and interbody cages have comparable mid- and long-term clinical and radiological outcomes.MethodsRetrospective analyses were performed on 120 patients who underwent single-level TLIF procedures with a minimum of two years of follow-up utilizing either the mini-open (n = 60) or MIS (n = 60) technique. Records of the operation's time frame, intraoperative fluoroscopy, blood loss, postoperative drainage volume, duration of bed rest, and complications were recorded. The Oswestry Disability Index (ODI) and visual analog scale (VAS) scores for both groups were utilized to assess improvements in clinical scores, and t tests were employed to statistically compare the outcomes. For comparison, radiological parameters, including lumbar lordosis, pelvic incidence (PI), and localized lordosis at the index level, were measured preoperatively, postoperatively, and at the final follow-up. To assess postoperative interbody fusion, the Bridwell grading system was used.ResultsIn the Mini-open TLIF group, the average follow-up time was 24.91 ± 5.7 months, while in the MIS-TLIF group, the average follow-up time was 25.15 ± 4.2 months. In the MIS-TLIF group, the mean operation and radiological time were longer. However, compared to the Mini-open TLIF group, the MISTLIF group experienced less blood loss and a shorter hospital stay. The MIS-TLIF group outperformed the Open-TLIF group in terms of the VAS score for back pain and the ODI at less than 6 months following surgery, and the differences were statistically significant. However, at the final follow-up, there were no statistically significant differences in the VAS score for the back between the two groups, but the ODI score was significantly greater in the MIS-TLIF group. Both groups' lumbar lordosis and focal lordosis significantly improved at the index level, with the Mini-open-TLIF group showing more focal lordosis. The interbody fusion rate did not significantly differ between the two groups.ConclusionMIS-TLIF and mini-open-TLIF can be surgically effective in treating single-level degenerative lumbar spine spondylolisthesis.

Significance of correcting magnesium deficiency in different groups of women in surgical menopause

Background. In the 21st century, there is a clear trend towards an increase in the proportion of women with climacteric syndrome (CS) and surgical menopause. Medical care for such patients usually includes menopausal hormone therapy (MHT), which often causes changes in magnesium and pyridoxine metabolism and their deficiency, leading to the development of adverse reactions. Therefore, it is necessary to improve rehabilitation programs designed to increаse the quality of life (QoL) for this category of gynecological patients.Objective: to assess the profile of women with CS and surgical menopause receiving and not receiving MHT and to identify the significance of magnesium deficiency (MD) effect on the recovery process.Material and methods. The observational non-interventional study included a total of 9168 women, of which 1528 patiеnts with CS and surgical menopause were taking MHT (Group 1), and 1528 patients with CS and surgical menopause were not taking MHT (Group 2). The Magnesium Deficiency Questionnaire (MDQ) was used to determine the number of participants with MD. A biochemical blood test was also performed, including determination of plasma magnesium concentration. The patients’ profile was analyzed for general somatic pathologies, obstetric and gynecological history, complaints, and MD symptoms using visual analogue scale. To assess QoL before the start of 4-week MD replenishing course and at the end of therapy, the World Health Organization Quality of Life Questionnaire (WHOQL-26) was applied.Results. The MDQ data showed that the prevalence of DM in Group 1 was higher compared to Group 2. In both groups, women with hypomagnesemia had a higher incidence of viral infections, vegetative-vascular dystonia, osteochondrosis and arterial hypertension, more pronounced sleep disorders, irritability, back pain, rapid fatigue, and higher MDQ scores. After completion of the course of therapy with magnesium citrate and pyridoxine combination, the MDQ scores in patients with DM decreased along with an increase in plasma magnesium concentration. Besides, women's satisfaction with their physical, psychological, social wellbeing and microsocial support increased, and self-perception improved. A decrease in the severity of DM and a significant improvement in QoL according to WHOQOL-26 were demonstrated in patients with CS and surgical menopause after therapy.Conclusion. The profile of patients with CS and surgical menopause, regardless of MHT, is often characterized by DM and decreased QoL. It seems reasonable to include blood magnesium level monitoring and DM correction in the comprehensive rehabilitation program for such patients.

Comparison of clinical and radiographic outcomes in unilateral transforaminal lumbar interbody fusion: a retrospective analysis of three surgical approaches.

The primary objective of this study is to evaluate and compare the clinical and radiographic outcomes of the combined spinous process-splitting approach with a Wiltse (SPSW) approach, the combined conventional approach with a Wiltse (CW) approach, and the conventional open (CO) approach in unilateral transforaminal lumbar interbody fusion (TLIF). The clinical outcomes were assessed, and intraoperative data and complications were collected. Numeric Rating Scale (NRS) scores for low back pain and leg pain, the Japanese Orthopaedic Association Back Pain Evaluation Questionnaire (JOABPEQ) scores for evaluating functions of the lumbar spine and health-related quality of life, and the modified MacNab standard for assessing satisfaction were analyzed. Radiographic outcomes included disc space height, segmental lordosis, interbody fusion assessment, and the rate of muscle atrophy of the multifidus and the erector spinae muscles. Among the three groups, the SPSW group exhibited the shortest operation and drain retention time, lowest intraoperative blood loss, and minimal postoperative blood loss. Notably, the SPSW group displayed the highest level of social life function based on the JOABPEQ, and the highest level of patient satisfaction according to the modified MacNab Criteria, along with the lowest rate of muscle atrophy. All the SPSW, CW, and CO approach TLIF procedures achieved overall satisfactory effects of decompression and fusion for lumbar degenerative diseases. The SPSW approach procedure appears to be associated with the smallest surgical trauma and highest satisfaction because of reducing iatrogenic injury of the paraspinal muscles.

Effectiveness of Interspinous Process Devices in Managing Adjacent Segment Degeneration Following Lumbar Spinal Fusion: A Systematic Review and Meta-Analysis.

Background: Adjacent segment degeneration (ASD) is a significant complication following lumbar spinal fusion, often necessitating further surgical interventions and impairing patient outcomes. Interspinous process devices were introduced as an alternative treatment for spinal stenosis and degenerative spondylolisthesis and can potentially reduce the incidence of ASDd. This systematic review and meta-analysis aims to evaluate the effectiveness of interspinous process devices or IPDs in managing ASD following a previous spinal fusion compared to traditional fusion techniques. Methods: Electronic databases, including PubMed, Embase, and the Cochrane Library, were queried for studies assessing IPDs against traditional lumbar fusion methods for managing ASD after previous lumbar fusion, which had been published between January 2014 and the present. Statistical analysis was conducted using Review Manager 5.4. Results: Seven retrospective cohort studies involving 546 patients met the inclusion criteria. The analysis revealed that IPDs were associated with a statistically significant reduction in the incidence of ASD (OR = 0.28, 95% CI: 0.16 to 0.51, p < 0.0001, and I2 = 0% after excluding outliers). The ODI demonstrated a non-significant trend towards improved outcomes with IPDs at the 2-year follow-up (SMD = -3.94; 95% CI: -11.72 to 3.85). Range of motion (ROM) was better preserved with IPDs compared to fusion (SMD = 0.00, 95% CI: -0.41 to 0.41, p = 1.00, I2 = 60%). The visual analogue scale or VAS lower back pain scores were significantly reduced at the 2-year follow-up (SMD = -0.69, 95% CI: -1.18 to -0.19, p = 0.006, and I2 = 74%). VAS leg pain showed consistent improvements (SMD = -0.29; 95% CI: -0.63 to 0.04). Intraoperative blood loss was significantly lower with IPDs (SMD = -2.07; 95% CI: -3.27 to -0.87, p = 0.0007, and I2 = 95%), and operation times were shorter (SMD = -2.22, 95% CI: -3.31 to -1.12, p < 0.0001, and I2 = 94%). Conclusions: The judicious use of IPDs might benefit a subset of patients, particularly those who are not suitable candidates for major corrective surgery.

Fall Trajectories in Older Men: Trajectories of Change by Age and Predictors for Future Fall Risk.

Very little is known about specific trajectories or patterns of falls over time. Using the well-characterized cohort of the Osteoporotic Fractures in Men Study (MrOS), we classified individuals by fall trajectories across age and identified predictors of group assignment based on characteristics at baseline. Using an analysis sample of 5976 MrOS participants and 15 years of follow-up data on incident falls, we used group-based trajectory models (PROC TRAJ in SAS) to identify trajectories of change. We assessed the association of baseline characteristics with group assignment using one-way analysis of variance (ANOVA) and chi-square tests. Multivariable logistic regression was used to analyze the outcome of the high risk fall trajectory groups compared to the low risk groups. Changes in rates of falls were relatively constant or increasing with five distinct groups identified. Mean posterior probabilities for all five trajectories were similar and consistently above 0.8 indicating reasonable model fit. Among the five fall trajectory groups, two were deemed high risk, those with steeply increasing fall risk and persistently high fall risk. Factors associated with fall risk included body mass index, use of central nervous agents, prior history of diabetes and Parkinson's disease, back pain, grip strength, and physical and mental health scores. Two distinct groups of high fall risk individuals were identified among five trajectory groups, those with steeply increasing fall risk and persistently high fall risk. Statistically significant characteristics for group assignment suggest that future fall risk of older men may be predictable at baseline.

Prospective comparative analysis of three types of decompressive surgery for lumbar central stenosis: conventional, full-endoscopic, and biportal endoscopic laminectomy

Conventional open laminectomy has long been considered one of the important surgical options for lumbar central stenosis owing to its positive outcomes. However, newer approaches have emerged as alternatives, including full-endoscopic and biportal endoscopic laminectomy. Therefore, a comparison of the outcomes that are associated with each of these surgical methods is warranted. This prospective multicenter trial, initiated in February 2019, compared the outcomes of three lumbar central stenosis surgical approaches: open laminectomy (OPEN), uniportal endoscopy (UNIPORT), and biportal endoscopy (BIPORT). Among 115 participants from seven centers, one-year follow-ups assessed laboratory, radiological, and clinical outcomes. Despite all groups showing adequate decompression and clinical improvement, the OPEN group exhibited less improvement in Visual analog scale (VAS) for back pain scores (p < 0.05) and significant postoperative increases in most laboratory markers. Furthermore, the OPEN group experienced a significant decrease in multifidus muscle cross-sectional area compared to endoscopic groups (p < 0.001). Each surgical techniques produced similar clinical outcomes and dural space expansion. However, endoscopic surgery was associated with better muscle preservation and better relief of back pain. Endoscopic surgery is a reasonable alternative to conventional laminectomy for treating lumbar central stenosis.This trial was registered on CRIS (Clinical Research Information Service, KCT0004355).

A Novel Classification of Migrated Lumbar Disk Herniation Based on Magnetic Resonance Imaging and Algorithm Recommendations for Full-Endoscopic Discectomy.

Retrospective clinical study. The purpose of this study was to establish a novel classification of migrated lumbar disk herniation (LDH) based on magnetic resonance imaging and provide appropriate treatment strategies for each type through algorithms. Full-endoscopic lumbar discectomy is a surgical technique that has been developed rapidly in recent years. For migrated LDH, few surgeons currently classify it with multiplanar positioning, and there is no consensus on the choice of treatment strategy. Therefore, we established a new multiplanar classification criteria that can localize the lesions more accurately than previous studies. A total of 263 eligible patients from March 2017 to March 2022 were included. Protrusions for each patient were located based on our classification and the surgical approach was selected according to our algorithms. The clinical symptoms of all patients before surgery, and at 1 day, 1 month, 3 months, 6 months, and 12 months after surgery were collected. Evaluations were performed using visual analogue scale (VAS), Oswestry Disability Index (ODI) and modified MacNab criteria. We used the chi-squared test, one-way analysis of variance (ANOVA), and t-test to compare perioperative results and postoperative 3-month, 6-month, and 12-month follow-up results. VAS (low back pain) scores were reduced from 5.33 ± 2.67 to 0.73 ± 0.77 (p < 0.001), and VAS (leg pain) scores were reduced from 7.44 ± 2.21 to 0.37 ± 0.51 (p < 0.001). ODI scores improved from 58.46 ± 8.04 to 12.57 ± 2.51 (p < 0.001). According to the modified MacNab criteria, the excellent and good rate reached 92.78% at the 12-month follow-up. Twenty-six patients developed complications, all of which improved after treatment. Recurrence occurred in 13 patients, and four of them underwent secondary surgery. This is an innovative classification method using multi-plane positioning, and the algorithm used with it can help surgeons make appropriate choices when using endoscopic technology to treat migrated LDH. Statistical analysis of follow-up data confirmed that this is a safe and effective strategy.

Simultaneous Single-Position Oblique Lumbar Interbody Fusion and Percutaneous Pedicle Screw Fixation under O-Arm Navigation for Modified MISDEF Type II Adult Degenerative Scoliosis: Case Series and Surgical Technique.

Oblique lumbar interbody fusion (OLIF) has become a popular technique for treating adult degenerative scoliosis (ADS), but traditional OLIF technology often requires repositioning for one-stage or staged posterior fixation. The objective of this pilot study was to describe the surgical technique of simultaneous single-position OLIF and percutaneous pedicle screw fixation (OLIF 360) under O-Arm navigation for modified MISDEF type II ADS. Between June 2022 and December 2023, six patients classified as having modified MISDEF type II ADS underwent OLIF 360 assisted by O-Arm navigation at our institution. Intraoperative blood loss, duration of operation, and complications related to the OLIF 360 procedure were recorded. The preoperative and postoperative spinal pelvic parameters were measured using X-rays. The accuracy of pedicel screws was recorded in accordance with the modified Gertzbein-Robbins classification on CT. Postoperative MRI was performed to evaluate the indirect decompressive effect. The Japanese Orthopedic Association score for low back pain was used to evaluate surgical outcomes. Navigated OLIF 360 were performed in six ADS patients with 44 percutaneous pedicel screws and 16 cages placement, including four women and two men. The mean operation time was 160.83 ± 33.23 min, and the mean blood loss was 111.67 ± 39.71 mL. Postoperative spinal pelvic parameters and spinal stenosis degree improved significantly on X-ray and MRI. All screws were clinically acceptable according to the Gertzbein-Robbins classification, with 92.7% grade A and 7.3% grade B. No serious intraoperative and postoperative adverse events were recorded in all patients. The JOA scores for low back pain of all patients were significantly improved at postoperative 1 month and the final follow-up. We report on a case series and describe navigated OLIF 360 in treating modified MISDEF type II ADS patients. Navigation-assisted OLIF 360 has shown encouraging surgical outcomes with good spinal imbalance correction and indirect decompression.

Correlations of spinopelvic parameters with quality of life of patients with adult degenerative scoliosis after posterior correction.

This study aimed to investigate the correlations of spinopelvic parameters with the quality of life of patients with adult degenerative scoliosis (ADS) after posterior correction, and their relationships with efficacy Patients and methods: Ninety patients (40 females, 50 males; mean age: 62.4±3.3 years; range, 47 to 73 years) with adult spinal deformity treated from March 2016 to May 2020 were retrospectively enrolled. The Scoliosis Research Society (SRS)-22 questionnaire was filled in by the patients, and the Oswestry disability index (ODI) and Visual Analog Scale (VAS) for back and lower limb pain were assessed. All the patients underwent posterior correction. Spearman's analysis was conducted for the correlations of the spinopelvic sagittal parameters with quality of life. The risk factors for efficacy were identified using the multivariate logistic regression model to construct a nomogram model for efficacy and risk prediction. After the operation, significant reductions were detected in the sagittal vertical axis (SVA), pelvic tilt (PT), T1 pelvic angle (TPA), pelvic incidence minus lumbar lordosis (PI-LL), and the ODI score (p<0.05). The SVA and LL were significantly negatively correlated with all subitems on the SRS-22 questionnaire but positively correlated with VAS scores for back pain (p<0.05). Thoracic kyphosis was significantly positively correlated with self-image and mental status on the SRS-22 questionnaire (p<0.05), while TPA was negatively correlated with pain and self-image (p<0.05). The PI-LL was significantly negatively correlated with pain (p<0.05). The SVA, LL, PT, and PI-LL were independent predictors of improvement in ODI after operation for ADS. The postoperative changes in spinopelvic parameters affected the clinical outcomes in patients with ADS.

Oblique lumbar interbody fusion combined with anterolateral screw fixation and stress endplate augmentation for treating degenerative lumbar spondylolisthesis with osteoporosis.

To evaluate the outcomes of Oblique lumbar interbody fusion (OLIF)combined with anterolateral screw fixation (AF) and Stress Endplate Augmentation(SEA) versus OLIF-AF in the treatment of degenerative lumbar spondylolisthesis (DLS)with osteoporosis (OP). 30 patients underwent OLIF-AF-SEA (SEA group) were matched with 30 patients received OLIF-AF (control group), in terms of sex, age, body mass index (BMI) and bone mineral density (BMD). Clinical outcomes including visual analog scale (VAS) score of the lower back pain (VAS-LBP), leg pain (VAS-LP), and Oswestry Disability Index (ODI) were evaluated at different postoperative intervals and comparedwith their preoperative counterparts. Radiographic outcomes such as disk height (DH), slip distance (SD), lumbar lordosis (LL), segmental lordosis (SL), cage subsidence (CS) rate and fusion rate were evaluated at different postoperative intervals and compared with their preoperative counterparts. SEA group presented to be better at 3-month and 12-month follow-up, the VAS-LBP, VAS-LP and ODI scores of the SEA group were significantly lower than the control group (3-month SEA vs control: 2.30±0.70 vs 3.30±0.75, 2.03±0.72 vs 2.90±0.76,15.60±2.36 vs 23.23±3.07, respectively, all p<0.05. VAS-LBP and ODI 12-month SEA vs control: 1.27±0.74 vs 1.93±0.58, 12.20±1.88 vs 14.43±1.89,respectively, all p<0.05). At 24-month follow-up, both groups showed no difference in fusion rate (83.33% vs 90.00%, p=0.45), while SEA group showed a lower CS rate (13.33% vs 53.33%, p<0.05). OLIF-AF-SEA was safe with no adverse effects and resulted in lower CS rate and better sagittal balance. OLIF-AF-SEA is a promising surgical method for treating patients with DLS-OP.

Characteristics in patients with very early therapeutic response of condoliase chemonucleolysis for lumbar disc herniation.

Treatment of lumbar disc herniation (LDH) using condoliase chemonucleolysis (CC) requires more time than surgery to demonstrate therapeutic effects. This study aimed to identify patients who show significant improvement in leg pain very early after CC and to determine pretreatment factors that can predict a very early therapeutic response. The study included 52 patients who underwent CC for treatment-resistant LDH. Scores for low back and leg pain measured by a numerical rating scale were assessed at four time points (1day, 1 week, 1 month, and 3 months after CC). Patients who reported subjective pain relief the day after treatment and further exhibited an improved straight leg raising (SLR) angle compared to pretreatment were classified as "very early responders (VER)". Of the 52 patients, 39 (75%) were VER, and 13 (25%) were non-VER. The VER showed earlier improvement in leg pain. The VER had a significantly higher proportion of positive SLR test patients (p = 0.01) and a significantly smaller pretreatment SLR angle compared to the non-VER (VER vs. non-VER: 40.6 ± 19.0 vs. 63.1 ± 16.9, p < 0.001). There were no significant differences in the level, type, and size of LDH and the disc regression rate between the two groups. Patients with a smaller pretreatment SLR angle are more likely to experience very early or early symptomatic relief, with a significant and sustained reduction in leg pain up to 3 months after CC treatment.

Idiopathic pyogenic thoracic and lumbar spondylodiscitis: outcome of long segment fixation

BackgroundSpondylodiscitis is an infection of the vertebral body extending to the intervertebral disc, and possibly the surrounding paraspinal structures.ObjectivesTo evaluate the clinical results of posterior long segment transpedicular screws fixation and decompression of the infected area for management of idiopathic pyogenic spondylodiscitis of the thoracic and lumbar spine.MethodsThis retrospective study included 14 patients with idiopathic active pyogenic spondylodiscitis of the lumber and thoracic spine between January 2017 and December 2021, with follow-up continuing until December 2022. All patients had posterior long-segment rigid fixation with infection decompression.ResultsAll patients after 6-month follow-up had achieved complete fusion. There was no evidence of postoperative wound infection, and no patient had a recurrence of infection at the lesion site during follow-up. Prior to surgery, the mean VAS score for back pain was 7.6 (range 6–9), however, after surgery, it fell to 1.3 (0–3), a statistically significant improvement (P < 0.001) during the last follow-up. According to the Kirkaldy-Willis criteria, the functional prognosis was excellent in 11 individuals, good in two, and fair in one.ConclusionsPosterior long-segment fixation in conjunction with decompression of the affected area effectively resolved bacterial spinal infection and restored neurological impairment.

Ten-Year Follow-up of Posterior Decompression and Fusion Surgery for Thoracic Ossification of the Posterior Longitudinal Ligament.

We evaluated the clinical, functional, and quality of life (QoL) outcomes of surgical treatment of thoracic ossification of the posterior longitudinal ligament (T-OPLL). We retrospectively evaluated 51 patients followed for ≥10 years after posterior decompression and corrective fusion surgery for T-OPLL. The data collected included demographics, comorbidities, and pre- and postoperative symptoms. The Japanese Orthopaedic Association (JOA) score, numerical rating scale (NRS) for back and leg pain, and EuroQol-5 Dimension-5 Level (EQ-5D-5L) were used to assess neurological function, pain, and QoL. Imaging evaluations were conducted to assess changes in kyphotic angles and ossification progression. A significant improvement was observed in the JOA score from preoperatively (3.7) to 2 years postoperatively (7.9) (p < 0.05); the score remained stable thereafter. The mean EQ-5D-5L score improved from 0.53 preoperatively to 0.68 at 10 years postoperatively (p < 0.001). NRS scores for back and leg pain decreased from 5.4 to 3.5 and 4.0 to 3.0, respectively, from preoperatively to 10 years (p < 0.001 for both). Radiographic outcomes showed changes in kyphotic angles and ossification areas, with no significant progression after 2 years. Fourteen (27.5%) of the patients experienced postoperative complications. Of these, 8 (15.7%) required reoperation, 6 (11.8%) in the perioperative period and 2 (3.9%) later. Four (7.8%) of the patients underwent additional surgeries for conditions including lumbar spinal canal stenosis and cervical OPLL. Nonetheless, physical function in all cases with postoperative complications or additional surgery remained stable over the decade. Surgical treatment of T-OPLL is effective in improving neurological function, QoL, and pain management over an extended period. The long-term outcomes of T-OPLL surgery revealed that, although cervical and lumbar spinal lesions led to reoperations, they did not affect QoL, and relative improvement was maintained even after 10 years.

Is orthotic treatment beneficial for fresh osteoporotic vertebral fractures? A propensity score matching study

BACKGROUND CONTEXTOrthotic treatment is a common option for the conservative treatment of osteoporotic vertebral fractures (OVF). However, there is insufficient evidence of its clinical benefit. PURPOSETo investigate the effectiveness of orthotic treatment for OVF. STUDY DESIGN/SETTINGRetrospective cohort study with data from two prospective studies. PATIENT SAMPLEThis study included 160 patients with fresh OVF enrolled in 2012 and 2020 prospective cohort studies. OUTCOME MEASURESThe visual analog scale (VAS) score for low back pain was used for clinical outcomes, and radiographic parameters included the percent height of the vertebra and angular change of the vertebral body. Moreover, the occurrence of secondary vertebral fractures was followed-up over time. METHODSThe patients were divided into brace and no-brace groups and were matched according to propensity score for age, sex, anterior percent height at the initial examination, and presence of old OVFs. Hazard ratio for the cumulative incidence of secondary vertebral fractures with and without bracing were calculated and analyzed using the generalized Wilcoxon test. In addition, the brace group was divided into soft and rigid brace groups and compared with the no-brace group. RESULTSEach group had 61 cases after propensity score matching. There were no significant differences in the VAS improvement for low back pain and the change in percent height of the anterior and posterior walls from initial examination to 6 months after injury (p=.87, p=.39 and p=.14, respectively, mixed-effect models). Meanwhile, the mean angular change of fractured vertebrae was 4.3° / 3.2° initially and 1.2° / 2.5° at 6 months (the brace group / no-brace group, respectively; p=.007, mixed-effect models). A significant difference was also observed between the rigid brace group and the no-brace group (p=.008, mixed effect models). The incidence of secondary vertebral fractures was 1.6% / 11.4% at 1 month, indicating a significant difference (the brace group / no-brace group, respectively; p = .028). The hazard ratio for the cumulative incidence of secondary fractures due to orthotic treatment was 0.47 (95% confidence interval 0.20–1.09, p=.054). CONCLUSIONSAlthough orthotic treatment for fresh OVF did not relieve pain, it might contribute to the stabilization of the fractured vertebra, especially using a rigid brace.

Association Between Spinopelvic Parameters and Clinical Outcomes of Patients Treated With Transforaminal Platelet-Rich Plasma Injections for Lumbar Disc Prolapse.

Introduction Lumbar disc prolapse mainly occurs in the regions involving the L4-L5 and L5-S1 vertebrae. In this context, the significance of spinopelvic parameters becomes notably prominent. Non-invasive management of lumbar disc prolapse encompasses medicinal therapy, physical therapy, exercise, and epidural injections. Because of its autologous blood origin, platelet-rich plasma (PRP) therapy has minimal risks associated with immunogenic reactions and side consequences. We evaluated the extent of pain reduction and improvement of functional outcomes in patients having discogenic low back pain with modified spinopelvic parameters before and after undergoing transforaminal autologous PRP injection interventions. Methodology An observational study was conducted between September 2022 and August 2023 on 100 patients with low back pain for six months.The study populationcomprised patients whodid not respond to conservative treatment; they were recruited from the orthopaedicward of the emergency medicine department and outpatient department at the RLJalappa Hospital and Research Centre affiliated with Sri Devaraj Urs Medical College in Kolar, India. Every patient received a thorough evaluation that comprised an extensive medical history, a clinical examination, and imaging of the lumbosacral spine from both the front and side views. After obtaining the patient's consent and confirming their readiness for surgery, a PRPinjection was administered. The injection technique followed the standardized protocol and was performed by an experienced spine surgeon in collaboration with orthopaedic residents. Pain evaluations utilizing the Visual Analog Scale (VAS) and assessment of functional outcomes using the Oswestry Disability Index (ODI) scale were conducted before and after PRPinjections at the one- and six-month follow-ups. Results The average age of the study participants was 41.82 ± 5.0 years, with 55% of them being male. A total of 39% of study samples exhibited an increased angle in spinopelvic parameters. The independent t-test revealed a statistically significant difference in the mean score of back pain, limb pain, and ODI score between patients with increased and decreased angles of spinopelvic parameters before and after injection (p=0.0001). The severity of back pain, leg pain, and functional disability was significantly reduced in patients with increased angles of spinopelvic parameters following PRP injections at the one-month follow-up (p=0.0001). However, at the six-month follow-up, patients encountered recurring symptoms and worsening back pain, leg pain, and functional disability compared to the one-month follow-up. Conversely, the severity of back pain, leg pain, and functional disability has been markedly reduced in the patients with lower spinopelvic parameter angles following PRP injections at one month (p=0.0001) and six months (p=0.0001) compared to pre-injections. Conclusion During the long-term follow-up, subjects with elevated spinopelvic parameter angles reported a lower level of improvement in functional outcome, leg pain, and back pain. The impact of spinopelvic parameterson back pain severity and functional disability is substantial, significantly affecting the functional outcome of patients with lumbar disc prolapse.

Predictors of Delayed Clinical Benefit Following Surgical Treatment for Low Grade Spondylolisthesis.

Retrospective review of prospectively collected data. To investigate what factors predict delayed improvement after surgical treatment of low grade spondylolisthesis. Lumbar surgery leads to clinical improvement in the majority of patients with low grade spondylolisthesis. Most patients improve rapidly after surgery, but some patients demonstrate a delayed clinical course. The Quality and Outcomes Database (QOD) was queried for grade 1 spondylolisthesis patients who underwent surgery who had patient reported outcome measures (PROMs) collected at baseline, 3-, 6- and 12-months, including back and leg pain numeric rating scale (NRS), Oswestry Disability Index (ODI), and EuroQol-5D (EQ-5D). Patients were stratified as "Early responders" reaching MCID at 3 months and maintaining improvement through 12 months and "Delayed responders" not reaching MCID at 3 months but ultimately reaching MCID at 12 months. These two groups were compared with respect to factors which predicted delayed improvement. Of 608 patients enrolled, 436 (72%) met inclusion criteria for this study. Overall, 317 patients (72.7%) reached MCID for ODI at 12 months following surgery. Of these patients, 249 (78.5%) exhibited a rapid clinical improvement trajectory and had achieved ODI MCID threshold by the 3-month postop follow-up. 68 patients (21.4%) showed a delayed trajectory, and had not achieved ODI MCID threshold at 3 months, but did ultimately reach MCID at 12-month follow-up. Factors associated with delayed improvement included impaired preoperative ambulatory status, better baseline back and leg pain scores, and worse 3-month leg pain scores (P<0.01). The majority of patients undergoing surgery for low grade spondylolisthesis reach ODI MCID threshold rapidly, within the first three months after surgery. Factors associated with a delayed clinical course include impaired preoperative ambulation status, relatively better preoperative back and leg pain, and persistent leg pain at 3 months.

WITHDRAWN: Percutaneous Endoscopic Posterolateral Transforaminal Lumbar Interbody Fusion for the Treatment of Lumbar Degenerative Disease

Percutaneous endoscopic lumbar interbody fusion (PE-LIF) is commonly employed in treating a variety of lumbar degenerative diseases (LDD). This study evaluated the effectiveness and safety of a modified approach known as percutaneous endoscopic posterolateral transforaminal lumbar interbody fusion (PE-PTLIF). We conducted a retrospective review of 46 patients who underwent PE-PTLIF for LDD between November 2020 and July 2021. We analyzed measurements including pre- and postoperative Visual Analogue Scores (VAS) for lower back and leg pain, Oswestry Disability Index (ODI) collected at 3 days, 3 months, 6 months, and the most recent follow-up, and spinal parameters (disc space height, lumbar lordosis angle, and lumbar spondylolisthesis rate) over time. Patients were followed for an average duration of 18.6 months. Significant improvements were observed in VAS scores for lower back pain (latest follow-up: 1.21 ± 0.57) and leg pain (latest follow-up: 1.10 ± 0.72), as well as in ODI scores (latest follow-up: 9.63% ± 4.13) (all P<0.001 compared with preoperative values). Improvements were also noted in vertebral space height and lumbar lordotic angles (P<0.001). Postoperative complications included wound infection (6.5%), cerebrospinal fluid leakage (2.2%), and reduced dorsiflexion muscle strength (2.2%), all of which were successfully managed conservatively. There were no instances of epidural hematoma, internal fixation failure, or lumbar non-fusion/fusion device displacement. Confirmation of osseous fusion was obtained via lumbar X-ray/CT scans at the final follow-up. PE-PTLIF is a promising treatment option for specific LDD including spinal stenosis, lumbar spondylolisthesis, and lumbar instability, with favorable therapeutic outcomes demonstrated.
