Assessment of the prevalence and associated factors of lower back pain (LBP) among three different professionals in Bangladesh: Findings from a face-to-face survey.

OBJECTIVES: This study aims to evaluate the prevalence and associated factors of lower back pain (LBP) among farmers, rickshaw pullers and office workers in Bangladesh, while also investigating potential contributors within these occupational groups. DESIGN: This cross-sectional study aimed to determine the prevalence of LBP, associated factors and management procedures among farmers, rickshaw pullers and office workers in Bangladesh through face-to-face interviews. SETTING: The study was conducted in different parts of the Bogura district in Bangladesh. PARTICIPANTS: A total of 396 participants were included in the final analysis, all the participants were men and adult in age. MAIN OUTCOME MEASUREMENTS: Data were collected using a semi-structured questionnaire based on previous research. Bivariate and multivariable logistic regression analyses were performed to identify significant associations. RESULTS: The prevalence of LBP was found to be 42.7% among the participants. Farmers and rickshaw pullers had approximately four-times and three-times higher odds of experiencing LBP compared with office workers. Other significant factors associated with LBP included living in a nuclear family, having a normal body weight, lacking professional training, having a chronic disease, having a family history of LBP and experiencing numbness in the legs or feet. The majority of respondents sought medical attention and took medication for their LBP. CONCLUSION: The study underscores occupational differences in LBP prevalence, emphasising the necessity for tailored interventions and occupational health policies. Identifying specific risk factors and management practices in these professions can aid in developing effective prevention strategies and enhancing healthcare services.

The global health and economic impact of low-back pain attributable to occupational ergonomic factors in the working-age population by age, sex, geography in 2019.

OBJECTIVE: Occupational ergonomic factors (OEF) include physical exertion, demanding posture, repetitive work, hand-arm vibration, kneeling or squatting, rising, and climbing, which are risk factors for low-back pain (LBP). This study aimed to examine the prevalence, years lived with disability (YLD), healthcare costs, and productivity losses of LBP attributable to OEF by age, sex, World Health Organization region, and country in 2019. METHODS: In this cross-sectional study, prevalence and YLD were extracted from the Global Burden of Diseases, Injuries, and Risk Factors Study 2019. Employment statistics were obtained from the International Labor Organization websites. Health and economic impact was estimated for 192 countries and territories using the population attributable fraction method. RESULTS: Globally, OEF were responsible for 126.1 million prevalent cases of LBP and 15.1 million YLD in the working-age population (aged 15-84 years) in 2019, with the Western Pacific region suffering most. OEF-attributable LBP led to $216.1 billion of economic losses worldwide. Of these, $47.0 billion were paid in healthcare costs, with the public sector serving as the largest contributor (59.2%). High-income countries bore >70% of global economic burden, whereas middle-income countries experienced >70% of global YLD. Generally, more prevalent cases and healthcare costs were found among females, whereas more YLD, productivity losses, and total costs were found among males. CONCLUSIONS: Globally, OEF-attributable LBP presented a heavy burden on health and economic systems. Exercise together with education, active monitoring, evidence-based medical practices, alternative cost-effective solutions, and prioritizing health policies are needed.

Chronic Lower Back Pain in Weight Lifters: Epidemiology, Evaluation, and Management.

¼ Chronic lower back pain (LBP) is common in both nonathletes and weight lifters, but the diagnosis and treatment should be approached differently in these 2 populations based on the unique movement patterns causing the pain.¼ Injury rates of weight lifters are far less than those of contact sports, ranging from 1.0 to 4.4 injuries per 1,000 workout hours. However, the lower back was consistently one of the top 2 injury sites for weight lifters, accounting for anywhere from 23% to 59% of all injuries. LBP was most often associated with the squat or deadlift.¼ Guidelines for evaluating general LBP are applicable to weight lifters, including a thorough history and physical examination. However, the differential diagnosis will change based on the patient's lifting history. Of the many etiologies of back pain, weight lifters are most likely to be diagnosed with muscle strain or ligamentous sprain, degenerative disk disease, disk herniation, spondylolysis, spondylolisthesis, or lumbar facet syndrome.¼ Traditional recommended therapies include nonsteroidal anti-inflammatory drugs, physical therapy, and activity modification, which are often insufficient to resolve pain and prevent injury recurrence. Because most athletes will want to continue to lift weights, lifting-specific behavior modifications focused on improved technique and correcting mobility and muscular imbalances are important aspects of management in this patient population.

Clinical and economic burden of low back pain in low- and middle-income countries: a systematic review.

OBJECTIVES: Low back pain (LBP) is the leading cause of disability and work absenteeism globally, and it poses significant clinical and economic burden to individuals, health systems and the society. This study aimed to synthesise the clinical and economic burden of LBP in low-income and middle-income countries (LMICs). METHODS: A systematic review following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines was performed. PubMed, Medline, CINAHL, PsycINFO, AMED, Embase and Scopus databases were systematically searched for studies that examined the clinical and economic burden of LBP in LMICs, published from inception to 10 December 2021. Only studies with clearly stated methodologies and published in English were eligible for review. RESULTS: Nine studies met the inclusion criteria and were reviewed. Of these, three of them were clinical burden studies. The mean Newcastle-Ottawa Quality Assessment Scale (NOS) score of the included studies was 4, with an average from 3 to 6. The included studies were conducted in Argentina, Brazil, China, Ethiopia, Nigeria and Republic of Serbia. The rates of hospitalisation due to LBP ranged between 13.4% and 18.7%. Due to variation of methodological approaches, the reported cost estimates were inconsistent across the studies. A total cost of US$2.2 billion per population and US$1226.25 per patient were reported annually due to LBP. CONCLUSION: This systematic literature review suggests that LBP is associated with significantly high rates of hospitalisation and costs. As LBP is an important threat to the population, health professionals and policymakers are to put in place appropriate programmes to reduce the clinical and economic burden associated with LBP and improve the health outcomes of individuals with this condition in LMICs.

Comparison of ACGIH lifting threshold limit values to validated low back disorder lifting assessment methods outcomes.

BACKGROUND: Work-related low back pain (LBP) increases the workforce disability and healthcare costs. This study evaluated the LBD risk level associated with handling the ACGIH TLVs in lifting tasks corresponding to various horizontal and vertical zones. OBJECTIVE: The aim of this study was to compare the low-risk ACGIH TLV to risk outcomes from various validated lifting assessment methods, including the OSU LBD Risk Model, NIOSH Lifting Equation, and LiFFT. METHODS: Twenty-four subjects were recruited for this study to perform various lifting conditions. The various ergonomic assessment methods were then used to obtain the risk assessment outcomes. RESULTS: The selected assessment methods showed that the ACGIH-defined TLVs are associated with less than high-risk for LBD for all the assessed tasks. The findings showed a moderate agreement (Kendall's W = 0.477) among the various assessment methods risk outcomes. The highest correlation (ρ= 0.886) was observed between the NIOSH Lifting Equation and LiFFT methods risk assessment outcomes. CONCLUSION: The findings showed that ACGIH-defined TLVs possesses less than high-risk for LBD. The outcomes of the selected ergonomic assessment methods moderately agree to each other.

Efficacy and safety assessment of orthopedic device (LSM-01) for low back pain: A randomized, single-blinded, sham-controlled, parallel-group, pilot clinical trial.

BACKGROUND: Low back pain refers to pain that occurs mainly in lumbosacral spine, and is a clinically common symptom that 70% to 90% of people experience at least once during their lives. OBJECTIVES: We investigated the effect and safety of orthopedic device (LSM-01) for alleviate back pain caused by muscle tension in a randomized, single-blinded, sham-controlled, parallel-group, pilot trial to establish a basis for large-scale clinical trial. METHODS: A total of 30 subjects were randomly assigned to 2 group: treatment group (LSM-01) and control group (sham device) received treatment with each device 2 to 3 times a week for a total of 6 treatment for 2 weeks. Primary outcome was visual analog scale (VAS); Secondary outcomes were pressure pain threshold (PPT), oswestry disability index (ODI), and patient global impression of change (PGIC). Statistical analysis is performed for full analysis set (FAS) population. Analysis of covariance (ANCOVA) for mean difference of VAS change and Mixed models of repeated measurements (MMRM) for the trend of VAS change were conducted to compare the differences between 2 groups before and after participants got treatment with the clinical trial device. RESULTS: One participant dropped out due to personal reason and 29 participants completed the clinical pilot trial. We found that the degree of low back pain (VAS, PPT, PGIC) significantly decreased and after the trial in the treatment group compared to the control group. Also, there were no any side effects. CONCLUSION: LSM-01 can be effective in improving pain of low back pain. A future large-scale main trial will be conducted based on this pilot study results.

Meaning of patient global assessment when joint counts are low in rheumatoid arthritis.

OBJECTIVE: In patients with rheumatoid arthritis (RA) with low 28-joint tender and swollen joint counts but who assessed their disease as active, to evaluate whether activity reflected RA symptoms. METHODS: We carried out a cross-sectional study of patients in BRASS, a cohort of patients with established RA who had 28-joint counts assessed, scored their disease activity, identified their painful joints, and answered questions about other sites of pain and fatigue. Patients and their rheumatologists were asked about the presence of fibromyalgia. We examined whether patients reported pain in joints excluded from the 28-joint joint count (feet, ankles, hips, neck) and pain or symptoms probably unrelated to RA including low back pain, headache and fibromyalgia. Fatigue was not classified. Analyses were descriptive. RESULTS: Of 272 patients, 49 had tender and swollen joint counts <1 and a patient global assessment score of ≥3/10. 48/49 (95%) reported pain in joints excluded from the 28-joint count. Of these 49, 24 (45%) also had other symptoms especially low back pain. Fatigue was present in all patients. No patient had fibromyalgia. CONCLUSION: If joint counts <=1 are scored in 28 joints, patient global assessments of ≥3/10 often occur when there is pain in uncounted joints, joints that may respond to RA treatment.

Responsiveness of the Zurich Claudication Questionnaire, the Oswestry Disability Index, the Japanese Orthopaedic Association Back Pain Evaluation Questionnaire, the 8-Item Short Form Health Survey, and the Euroqol 5 dimensions 5 level in the assessment of patients with lumbar spinal stenosis.

PURPOSE: To assess the responsiveness of the Zurich Claudication Questionnaire (ZCQ), the Oswestry Disability Index, the Japanese Orthopaedic Association Back Pain Evaluation Questionnaire, the visual analog scale (VAS), the 8-Item Short Form Health Survey (SF-8), and the EuroQol 5 dimensions 5 level as methods of assessing outcomes of surgery for lumbar spinal stenosis. METHODS: We analyzed 218 patients who had undergone lumbar surgery for spinal stenosis and completed one year of follow-up. The internal responsiveness of each questionnaire and any domains was assessed by the effect size and standardized response mean. External responsiveness was assessed by the Spearman rank correlation coefficient and the receiver operating characteristics (ROC) curve. RESULTS: The most responsive assessments were "symptom severity" and "physical function" on the ZCQ, "walking ability" on the JOABPEQ, "leg pain" on the VAS, and "social function" on the JOABPEQ. The moderately responsive assessments were the physical component summary on the SF-8, the ODI, the EQ5D-5L, "low back pain" on the JOABPEQ, and "leg numbness" on the VAS. The least responsive assessments were "low back pain" on the VAS, "mental health" and "lumbar function" on the JOABPEQ, and the mental component summary on the SF-8. CONCLUSIONS: Because of its high responsiveness, "symptom severity" on the ZCQ is recommended as a primary tool for assessing outcome when designing prospective studies for lumbar spinal stenosis.

[Occupational low back pain in reports of workers' casualties between 2018 and 2019].

OBJECTIVES: Reports of workers' casualties include occupational low back pain (LBP), accounting for approximately 60% of compensable occupational disease. While LBP has become an important safety and health problem, the occurrence of occupational LBP has not been analyzed recently. This study aimed to evaluate the occurrence of occupational LBP in reports of workers' casualties between 2018 and 2019. METHODS: The study included 10,208 cases of occupational LBP (2018, n = 5,043; 2019, n = 5,165). Data on the location and date of industrial accidents, as well as type and size of business, age, sex, and leave period of the victims were tabulated. RESULTS: The number of occupational LBP cases was the highest in the health and hygiene industry (31.3%), followed by the commercial, manufacturing, and transportation industries. In the health and hygiene industry, social welfare facilities were listed in 24.3% of the total cases, and many caregivers suffered from LBP. Occupational LBP cases were less in cold regions and few during the cold period between November and January. Several occupational LBP cases occurred on Mondays following a holiday, and approximately 40% occurred between 9 a.m. and 12 a.m. Occupational LBP was frequently reported in workplaces with a volume of 10-49 workers, such as social welfare facilities in terms of business type. In terms of work-related accident victims per 100,000 workers, women were slightly more prone to LBP than men, and most of them were in their 20s and 30s. Approximately 60% of the leave period taken by victims was 2 weeks maximum. CONCLUSIONS: Occupational LBP was experienced by most workers in workplaces with at least 10-49 workers, such as social welfare facilities, between 2018 and 2019. In addition, LBP was more common in women than in men. Most workers with LBP take a leave period of 2 weeks. Suitable measures should be taken to prevent occurrences of occupational LBP.

The burden of low back pain, rheumatoid arthritis, osteoarthritis, and gout and their respective attributable risk factors in Brazil: results of the GBD 2017 study.

INTRODUCTION: Musculoskeletal (MSK) disorders are a major cause of disability worldwide. Different modifiable risk factors are associated to these disorders. The objective of this study was to analyze the burden of low back pain (LBP), rheumatoid arthritis (RA), osteoarthritis (OA), and gout, attributable to risk factors, in 2017. METHODS: The burden of LBP, RA, OA, and gout, and attributable risk factors were analyzed using data extracted from the Global Burden of Disease (GBD) Brasil-2017 study. Descriptive analysis was conducted to compare disability-adjusted life years (DALY) rates between sexes and age groups (15-49 and 50-69 years), in 2017. RESULTS: The highest rates of DALY due to LBP were attributed to occupational ergonomic factors in the 15-49-year group, regardless of sex and males aged 50-69 years, whereas smoking was the major contributor in the 50-69-year female group. RA-related DALY rates were attributed to smoking and were higher among women aged 50-69 years. High body mass index (BMI) was the most relevant risk factor for the burden of OA, with higher rates detected in the 50-69-year group, and it was the most significant risk factor for DALY rate attributed to gout, regardless of sex or age group. CONCLUSIONS: Occupational surveillance measures are indicated to prevent LBP. Actions to decrease smoking and overweight, and the surveillance of weight gain are warranted to decrease the burden of LBP, RA and OA, and gout, respectively. These actions will be more effective if age and sex differentials are considered in planning.

Epidemiology, diagnosis and management of Baastrup's disease: a systematic review.

INTRODUCTION: Baastrup's disease (BD) is a common cause of low back pain which is often underdiagnosed. It is characterized by adjacent interspinous processes contact and it can be associated with cystic lesions. The aim of this review was to evaluate the epidemiology, diagnosis, and treatment options of patients with BD. EVIDENCE ACQUISITION: The present study is performed according to PRISMA statement. Medline via PubMed and Embase, Scopus, Cochrane Library database were searched using the keywords: "Baastrup," "kissing spines," "syndrome," "disease." A total of 35 papers met our inclusion criteria. Full texts were reviewed for demographic, clinical data and treatment. EVIDENCE SYNTHESIS: 1308 patients were included in the studies. The mean age of the enrolled patients was 59.6 years. The M:F ratio was 1.3:1. Population-based studies demonstrated a decade on decade increase in the incidence. Standard and dynamic flexion-extension radiographs of the lumbar spine were performed in 213 (16.2%) of cases. MRI was performed in 735 patients (56.2%) whereas FDG PET/CT was used to demonstrate BD in 77 included cases (5.9%). CT scan was performed in 574 cases (43.9%). Twenty-six studies reported the treatment choice for a total of 277 patients. Anti-inflammatory drugs and physical therapy were chosen in 99 cases (35.7%). Percutaneous infiltrations and surgical decompression in 80 (28.9%) and 196 (70.7%) patients respectively. CONCLUSIONS: Baastrup's disease is a common cause of low back pain. Proper diagnosis needs for imaging investigations and dynamic flexion-extension radiographs. Conservative and surgical therapies are available but there is a need for randomized clinical trials.

Clinical assessment and management of Bertolotti Syndrome: a review of the literature.

Bertolotti Syndrome is a diagnosis given to patients experiencing pain caused by the presence of a lumbosacral transitional vertebra (LSTV), which is characterized by enlargement of the L5 transverse process(es), with potential pseudoarticulation or fusion with the sacrum. The Castellvi classification system is commonly utilized to grade LSTVs based on the degree of contact between the L5 transverse process(es) and the sacrum. LSTVs present a diagnostic dilemma to the treating clinician, as they may remain unidentified on plain x-rays and even advanced imaging; additionally, even if the malformation is identified, patients with a LSTV may be asymptomatic or have nonspecific symptoms, such as low back pain with or without radicular symptoms. With low back pain being extremely prevalent in the general population; it can be difficult to implicate the LSTV as the source of this pain. Care should be taken however, to exclude Bertolotti Syndrome in patients under 30 years old presenting with persisting low back pain given its congenital origin. If a LSTV is identified, typically with acquisition of a MRI or CT scan of the lumbosacral spine, and there is an absence of a more compelling or obvious source for the patient's symptoms, a conservative, step-wise management plan is recommended. This may include assessing for improvement in symptoms with injections prior to proceeding with surgical intervention. Additional concerns arise from the biomechanical alterations that a LSTV induces in adjacent spinal levels, predisposing this patient population to a more rapid-onset of adjacent segment disease, raising the question as to the most appropriate surgery (resection of LSTV pseudoarticulation with or without fusion). Postoperative outcome data for patients undergoing surgical treatment is limited in the literature with promising, but variable, results. More large-scale, controlled studies must be performed to gain further insight into the ideal work-up and management of this pathology.

The effectiveness of preoperative assessment using a patient-specific three-dimensional pseudoarticulation model for minimally invasive posterior resection in a patient with Bertolotti's syndrome: a case report.

BACKGROUND: Bertolotti's syndrome is widely known to cause low back pain in young patients and must be considered as a differential diagnosis. Its treatment such as conservative therapy or surgery remains controversial. Surgical procedure is recommended for intractable low back pain. The three-dimensional (3D) lumbosacral transitional vertebrae anatomy should be completely understood for a successful surgery. Using an intraoperative 3D navigation and preoperative preliminary surgical planning with a patient-specific 3D plaster model contribute for safe surgery and good outcome. CASE PRESENTATION: A case of a 22-year-old Japanese male patient with intractable left low back pain due to lumbosacral transitional vertebrae with Bertolotti's syndrome. The symptom resisted the conservative treatment, and anesthetic injection at pseudoarticulation only provided a short-term pain relief. Posterior resection using intraoperative three-dimensional (3D) navigation has been performed through microendoscopic view. Pseudoarticulation was totally and successfully resected in a safe manner. CONCLUSIONS: Preoperative surgical planning and rehearsal using a patient-specific 3D plaster model was greatly useful and effective for surgeons in performing accurate and safe pseudoarticulation resection.

Prevalence and Potential Risk Factors for Occupational Low Back Pain Among Male Military Pilots: A Study Based on Questionnaire and Physical Function Assessment.

Objectives: Low back pain (LBP) has negative implications for the military's combat effectiveness. This study was conducted to determine the prevalence and risk factors of LBP among pilots through a questionnaire and physical function assessments. Methods: Data on the demographic and occupational characteristics, health habits, physical activity, and musculoskeletal injuries of 217 male pilots (114 fighter, 48 helicopter, and 55 transport pilots) were collected using a self-reported questionnaire and physical function assessments. Results: LBP prevalence was 37.8% in the total cohort and 36.0, 45.8, and 34.5% among fighter, helicopter, and transport pilots, respectively. Multivariate regression analysis revealed that the risk factors significantly associated with LBP were neck pain [odds ratio (OR): 3.559, 95% confidence interval (CI): 1.827-6.934], transversus abdominis activation (OR: 0.346, 95% CI: 0.172-0.698), and hip external rotator strength (OR: 0.001, 95% CI: 0.000-0.563) in the total cohort; neck pain (OR: 3.586, 95% CI: 1.365-9.418), transversus abdominis activation (OR: 0.268, 95% CI: 0.094-0.765), hip external rotator strength (OR: 0.000, 95% CI: 0.000-0.949), and weekly flying hours (OR: 3.889, 95% CI: 1.490-10.149) in fighter pilots; irregular strength training (OR: 0.036, 95% CI: 0.003-0.507) and hip external rotator strength (OR: 0.000, 95% CI: 0.000-0.042) in helicopter pilots; and neck pain (OR: 6.417, 95% CI: 1.424-28.909) in transport pilots. Conclusions: High volume flight schedules and weak core muscle functions have significant negative effects on pilots' back health. LBP is commonly associated with high weekly flying hours, worsening neck pain, transversus abdominis insufficient activation, and reduced hip extensor/rotator strength. Risk factors vary among pilots of different aircraft. Thus, specific core muscle training would be especially important for military pilots.

Assessment of disability levels in patients with low back pain based on the type of lumbar spinal disorder.

BACKGROUND: Low back pain (LBP) is a common health condition and the leading cause of activity limitation and absenteeism in most parts of the world. One-fifth of patients with LBP develop chronic pain disability. OBJECTIVE: This study investigated the disability levels in patients with different types of lumbar spinal disorders. METHODS: A total of 528 patients visiting spine clinics between June 2017 and February 2018 were enrolled in this study. A demographic checklist, the patients' medical records, the Oswestry Disability Questionnaire, and the Visual Analog Scale (VAS) were used to collect the data. RESULTS: Non-specific LBP (29.5%) and discopathy (27%) were the most common final diagnoses. The obtained Oswestry Disability Index (ODI) was significantly higher in older patients, those with higher body mass index, more work experience, and smokers. Lower ODI was found in individuals with a history of regular exercise. Most individuals in all diagnostic groups were categorized into the high ODI group (p⩽ 0.001). CONCLUSION: In patients with lumbar spine lesions, ODI is significantly correlated with age, BMI, work experience, smoking, and the type of disorder (discopathy, spondylolysis, and spondylolisthesis). Regular exercise is associated with lower levels of disability.

Analysis of Clinical and Radiological Outcomes of Posterior Dynamic Stabilization for Direct Repair of Bilateral L5 Pars Interarticularis Defect: Dynamic Assessment of Pars Fusion.

AIM: To evaluate the satisfactory clinical and radiological outcomes of posterior dynamic stabilization for the direct repair of bilateral L5 pars interarticularis defects and pars fusion. MATERIAL AND METHODS: This is a retrospective evaluation of postoperative follow-up results of 13 patients with bilateral L5 pars interarticularis defects without spondylolisthesis. The patients underwent dynamic transpedicular stabilization between 2013 and 2018. Our surgical criteria included unilateral or bilateral L5 spondylolysis; excessive low back pain; low back pain accompanied by leg pain without neurological findings; symptoms lasting at least six months despite conservative treatments, age < 50 years; and lack of significant adjacent disc degeneration. RESULTS: There were seven female and six male patients with a mean age of 38.9 years. All patients achieved satisfactory postoperative results during a mean follow-up period of 22 months. Preoperative visual analog scale score and Oswestry Disability Index value were 8.85 ± 0.69 and 54.46 ± 7.62, respectively, which decreased to 1.31 ± 0.48 and 9.85 ± 3.51, respectively, at the postoperative 24th month. In all patients, the bony fusion of the pars interarticularis at the stabilized segment was confirmed on the computed tomography scan at an average of 22 months postoperatively. CONCLUSION: The posterior dynamic system ensures that the spine moves within physiological limits and carries the load by sharing it with the spine. The advantages of direct pars repair using our technique are the restoration of the posterior structures? normal anatomy, protection of the functional mobility segment, and early functional recovery without degeneration in the adjacent segment. Therefore, when there is no significant instability, patients with spondylolysis can be treated with posterior dynamic stabilization techniques with satisfactory clinical and radiological results.

Evaluation of persons with suspected lumbosacral and cervical radiculopathy: Electrodiagnostic assessment and implications for treatment and outcomes (Part I).

Persons with back, neck, and limb symptoms constitute a major referral population to specialists in electrodiagnostic (EDX) medicine. The evaluation of these patients involves consideration of both the common and less common disorders. The EDX examination with needle electromyography (EMG) is the most important means of testing for radiculopathy. This test has modest sensitivity but high specificity and well complements imaging of the spine. Needle EMG in combination with nerve conduction testing is valuable in excluding entrapment neuropathies and polyneuropathy-conditions that frequently mimic radicular symptoms. In this first of a two-part review, the optimal EDX evaluation of persons with suspected radiculopathy is presented. In part two, the implications of EDX findings for diagnosis and clinical management of persons with radiculopathy are reviewed.

One-stage posterior debridement, bone grafting fusion, and mono-segment vs. short-segment fixation for single-segment lumbar spinal tuberculosis: minimum 5-year follow-up outcomes.

BACKGROUND: To compare the clinical and radiological outcomes between posterior mono-segment and short-segment fixation combined with one-stage posterior debridement and bone grafting fusion in treating single-segment lumbar spinal tuberculosis (LSTB). METHODS: Sixty-two patients with single-segment LSTB treated by a posterior-only approach were divided into two groups: short-segment fixation (Group A, n = 32) and mono-segment fixation (Group B, n = 30). The clinical and radiographic outcomes were analyzed and compared between the two groups. RESULTS: The intraoperative bleeding volume, operation time, and hospitalization duration were lower in Group B than in Group A. All patients achieved the bony fusion criteria. The visual analog scale score, Japanese Orthopedic Association score, and Oswestry Disability Index were substantially improved 3 months postoperatively and at the last visit in both groups, with no significant difference between the two groups (P > 0.05). Kirkaldy-Willis functional evaluation at the final follow-up demonstrated that all patients in both groups achieved excellent or good results. The difference in the angle correction rate and correction loss between Groups A and B was not significant (P > 0.05). CONCLUSIONS: One-stage posterior debridement, bone grafting fusion, and mono-segment or short-segment fixation can provide satisfactory clinical and radiological outcomes. Mono-segment fixation is more suitable for the treatment of single-segment LSTB because the lumbar segments with normal motion can be preserved with less trauma, a shorter operation time, shorter hospitalization, and lower costs.

Comparing the short-term cost-effectiveness of epidural steroid injections and medical management alone for discogenic lumbar radiculopathy.

OBJECTIVE: Epidural steroid injections (ESIs) are a commonly used treatment strategy for low back pain and lumbar radiculopathy. However, their cost-effectiveness and ability to mediate long-term quality of life (QOL) improvements is debated. We sought to analyze the cost-effectiveness of lumbar epidural steroid injections (ESIs) compared to medical management alone for patients with lumbar radiculopathy and low back pain. PATIENTS AND METHODS: QOL outcomes were prospectively collected at 3- and 6-months following initial consultation. Metrics included the EuroQol-5 Dimensions (EQ-5D) questionnaire, the Pain Disability Questionnaire (PDQ), the Patient Health Questionnaire (PHQ-9) and the Visual Analogue Scale (VAS). Cost estimations were based on Medicare national payment amounts, median income, and missed workdays. A cost-utility analysis was performed based upon cost estimations and a cost-effectiveness threshold of $100,000/Quality-adjusted life year (QALY). RESULTS: One hundred forty-one patients met our inclusion/exclusion criteria; 89 received ESI and 52 were treated with medical management alone. Both cohorts showed improved EQ-5D scores at 3 months but were similar to one another: ESI (ΔEQ-5D = 0.06; p = 0.03) and medical-alone (ΔEQ-5D = 0.07; p = 0.03). No significant difference was seen between groups for total costs ($2,190 vs. $1,772; p = 0.18) or cost-utility ratios ($38,710/QALY vs. $27,313/QALY; p = 0.73). At both the 3-month and 6-month endpoints, absolute differences in cost-utility was driven by overall costs as opposed to QALY gains. Medical management alone was more cost effective at both points owing to lower expenditures, however these differences were not significant. No benefits were seen in either group on the EQ-5D or any of the patient reported outcomes at the 6-month time point. CONCLUSION: ESIs were not cost-effective at either the 3-month or 6-month follow-up period. At 3 months, ESIs provide similar improvements in QOL outcomes relative to medical management and at similar costs. At 6 months, neither ESIs nor conservative management provide significant improvements in QOL outcomes.

Evaluation criteria for the assessment of occupational diseases of the lumbar spine - how reliable are they?

BACKGROUND: In 2005, the German Association of Occupational Accident Insurance Funds (DGUV) defined radiological evaluation criteria for the assessment of degenerative occupational diseases of the lumbar spine. These include the measurement of intervertebral osteochondrosis and classification of vertebral osteosclerosis, antero-lateral and posterior spondylosis, and spondyloarthritis via plain radiography. The measures currently remain in daily use for determining worker compensation among those with occupational diseases. Here, we aimed to evaluate the inter- and intra-observer reliability of these evaluation criteria. METHODS: We enrolled 100 patients with occupational degenerative diseases of the lumbar spine. Native antero-posterior and lateral radiographs of these patients were evaluated according to DGUV recommendations by 4 observers with different levels of clinical training. Evaluations were again conducted after 2 months to assess the intra-observer reliability. RESULTS: The measurement of intervertebral osteochondrosis showed good inter-observer reliability (ICC: 0.755) and excellent intra-observer reliability (ICC: 0.827). The classification of vertebral osteosclerosis exhibited moderate kappa values for inter-observer reliability (К: 0.426) and intra-observer reliability (К: 0.441); the remaining 3 criteria showed poor inter- and intra-observer reliabilities. CONCLUSION: The measurement of intervertebral osteochondrosis and classification of vertebral osteosclerosis showed adequate inter- and intra-observer reliability in the assessment of occupational diseases of the lumbar spine, whereas the classification of antero-lateral and posterior spondylosis and spondyloarthritis stage exhibited insufficient reliability. Hence, we recommend the revision of the DGUV recommendations for the evaluation of occupational diseases of the lumbar spine.
