Standard posterior cervical fusion is a common surgical technique that utilizes lateral mass screws and rods for fixation. A relatively new, minimally invasive technique involving interfacet decortication and placement of spacers has shown promise in terms of outcomes. We sought to determine fusion rates and complications of this new technique at our institution to bolster current literature. We retrospectively reviewed all patients that underwent a 3-level or less minimally invasive posterior cervical fusions by a single surgeon. Patients were evaluated to determine fusion rates and postoperative complications. Twenty-eight patients underwent minimally invasive posterior cervical fusion. Twenty-seven demonstrated fusion (96%). One patient that underwent the procedure for juxta-fusional disease required additional surgery for pseudoarthrosis. The minimally invasive posterior cervical technique results in favorable fusion rates and has low complication rates. Our study strengthens current literature that this minimally invasive technique is a safe and effective alternative. [ABSTRACT FROM AUTHOR]

Objective Long-term follow-ups of prehabilitation programs for lumbar spine surgery are lacking, and more comprehensive evaluations are needed. In the current study, we evaluated the long-term effects of a prehabilitation program compared with conventional care in relation to lumbar fusion surgery in patients with degenerative disc disease. Methods Patients (n = 118) receiving lumbar fusion surgery were included in a multicenter randomized controlled trial, involving 1 university hospital and 2 spine clinics. The intervention was a person-centered prehabilitation program based on cognitive-behavioral physical therapy that targeted psychological presurgical risk factors, physical activity, and overall health. The control group received conventional preoperative care. Patient-reported outcome measures (PROMs) included assessments at 8 time-points: low back disability (primary outcome), back pain intensity, leg pain intensity, pain catastrophizing, fear of movement, anxiety and depressive mood, health-related quality of life, and patient-specific functioning. Physical activity and physical capacity were assessed at 5 time points. Linear mixed models were used to analyze the effects of the intervention. Results There were no significant differences between groups at the 12- and 24-month follow-ups for any outcome, except for the One Leg Stand test 1 year following surgery, in favor of the control group. There were significant improvements for both groups, from baseline to the 12- and 24-month follow-ups for all physical capacity test and patient-reported outcome measures, except for leg pain and self-efficacy for exercise. Conclusion No long-term effects were found for the prehabilitation program compared to conventional care. Physical activity did not improve over time, despite significantly improved self-reported functioning and physical capacity measurements. Impact These findings have implications for the current understanding of the long-term effects of prehabilitation and suggest that future research should focus on programs promoting physical activity both before and after lumbar spine surgery to decrease the risk of long-term adverse health outcomes.

Diabetes predisposes to spine degenerative diseases often requiring surgical intervention. However, the statistics on the prevalence of spinal fusion success and clinical indications leading to the revision surgery in diabetes are conflicting. The purpose of the presented retrospective observational study was to determine the link between diabetes and lumbar spinal fusion complications using a database of patients (n  = 552, 45% male, age 54 ± 13.7 years) residing in the same community and receiving care at the same health care facility. Outcome measures included clinical indications and calculated risk ratio (RR) for revision surgery in diabetes. Paravertebral tissue recovered from a non-union site of diabetic and nondiabetic patients was analyzed for microstructure of newly formed bone. Diabetes increased the RR for revision surgery due to non-union complications (2.80; 95% CI, 1.12–7.02) and degenerative processes in adjacent spine segments (2.26; 95% CI, 1.45–3.53). In diabetes, a risk of revision surgery exceeded the RR for primary spinal fusion surgery by 44% (2.36 [95% CI, 1.58–3.52] vs 1.64 [95% CI, 1.16–2.31]), which was already 2-fold higher than diabetes prevalence in the studied community. Micro-CT of bony fragments found in the paravertebral tissue harvested during revision surgery revealed structural differences suggesting that newly formed bone in diabetic patients may be of compromised quality, as compared with that in nondiabetic patients. In conclusion, diabetes significantly increases the risk of unsuccessful lumbar spine fusion outcome requiring revision surgery. Diabetes predisposes to the degeneration of adjacent spine segments and pseudoarthrosis at the fusion sites, and affects the structure of newly formed bone needed to stabilize fusion.

Endoscopic spine surgery has evolved exponentially. However, the two-dimensional (2D) view results in lack of stereoscopic vision and depth perception, contributing to the steep learning curve. This case report recounts a world first trial of a three-dimensional (3D) endoscopic system that converts 2D to 3D images and explores its potential role in the surgical management of degenerative lumbar spine diseases. The 3D endoscopic system was used for two patient cases and both 2D and 3D images were displayed side by side and compared. Advantages of the 3D endoscopic system include increased perception of depth, rapid identification of bleeding points, and greater visualization of anatomical details. Field of view and exposure were identical in 2D and 3D views. Limitations include costs and need for additional equipment. Overall, 3D endoscopy improved depth perception, instrument manoeuvrability, and recognition of anatomical details. This case report can guide further research and training in endoscopic spine surgery. [ABSTRACT FROM AUTHOR]

Multiple myeloma is the most common primary malignant disease of the spine, which can lead to pathological fractures with consecutive instability and immobilizing pain, due to osseous destruction of individual vertebral bodies. The different surgical care is challenging, although good stabilization should be achieved if possible. The resulting blocking of micro-movements leads to pain minimization. However, this is a symptomatic therapy and does not address the primary disease. In the following, we report on successful transoral balloon kyphoplasty for the treatment of myeloma-related osteolysis with a pathological fracture of vertebral body C2, which led to a significant clinical improvement.

Background Hematogenous vertebral osteomyelitis (HVOM) is an incompletely understood complication of Staphylococcus aureus bacteremia (SAB). Methods Eligible SAB patients with and without HVOM were prospectively enrolled from 1995 through 2019 at Duke University Health System. HVOM was diagnosed either radiographically or microbiologically. Multivariable logistic regression analysis was performed to identify clinical and microbial factors associated with HVOM risk. All bloodstream S. aureus isolates were genotyped using spa typing. Results Of 3165 cases of SAB, 127 (4.0%) developed HVOM. Patients who experienced HVOM were more likely to have community-acquired SAB (30.7% vs 16.7%, P <.001), have a longer time to diagnosis of SAB (median, 5 days; interquartile range [IQR], 2–10.5 vs median, 2 days; IQR, 0–4; P <.001), and to exhibit persistent bacteremia (48.8% vs 20.6%, P <.001). A significant number of HVOM patients developed infective endocarditis (26% vs 15.2%, P =.002). Overall, 26.2% (n = 33) of SAB patients with HVOM underwent surgical intervention. Methicillin resistance (46.6% vs 41.7%, P =.318) and bacterial genotype were not associated with the development of HVOM. At the 12-month follow-up, 22% of patients with HVOM had died. Of the surviving patients, 20.4% remained on antibiotic therapy, and 29.6% had recurrence of either HVOM or SAB. Conclusions Among patients with SAB, HVOM risk was associated with clinical factors and not bacterial genotype. Despite being a rare complication of SAB, patients with HVOM had high all-cause mortality rates and healthcare resource requirements up to 1 year after their HVOM diagnosis. Close clinical monitoring is indicated in this vulnerable population. [ABSTRACT FROM AUTHOR]

Background and Objectives Globally, older adults are undergoing spine surgery for degenerative spine disease at exponential rates. However, little is known about their experiences of living with and having surgery for this debilitating condition. This study investigated older adults' understanding and experiences of living with and having surgery for degenerative spine disease. Research Design and Methods Qualitative methods, grounded theory, guided the study. Fourteen older adults (≥65 years) were recruited for in-depth interviews at 2 time-points: T1 during hospitalization and T2, 1–3-months postdischarge. A total of 28 interviews were conducted. Consistent with grounded theory, purposive, and theoretical sampling were used. Data analysis included open, axial, and selective coding. Results A conceptual model was developed illustrating the process older adults with degenerative spine disease experience, trying to get their life back. Three key categories were identified (1) Losing Me , (2) Fixing Me , and (3) Recovering Me. Losing Me was described as a prolonged process of losing functional independence and the ability to socialize. Fixing Me consisted of preparing for surgery and recovery. Recovering Me involved monitoring progression and reclaiming their personhood. Conditions, including setbacks and delays, slowed their trajectory. Throughout, participants continually adjusted expectations. Discussion and Implications The conceptual model, based on real patient experiences, details how older adults living with and having surgery for degenerative spine disease engage in recovering who they were prior to the onset of symptoms. Our findings provide a framework for understanding a complex, protracted trajectory that involves transitions from health to illness working toward health again. [ABSTRACT FROM AUTHOR]

Management of patients suffering from low back pain (LBP) is challenging and requires development of diagnostic techniques to identify specific patient subgroups and phenotypes in order to customize treatment and predict clinical outcome. The Back Pain Consortium (BACPAC) Research Program Spine Imaging Working Group has developed standard operating procedures (SOPs) for spinal imaging protocols to be used in all BACPAC studies. These SOPs include procedures to conduct spinal imaging assessments with guidelines for standardizing the collection, reading/grading (using structured reporting with semi-quantitative evaluation using ordinal rating scales), and storage of images. This article presents the approach to image acquisition and evaluation recommended by the BACPAC Spine Imaging Working Group. While the approach is specific to BACPAC studies, it is general enough to be applied at other centers performing magnetic resonance imaging (MRI) acquisitions in patients with LBP. The herein presented SOPs are meant to improve understanding of pain mechanisms and facilitate patient phenotyping by codifying MRI-based methods that provide standardized, non-invasive assessments of spinal pathologies. Finally, these recommended procedures may facilitate the integration of better harmonized MRI data of the lumbar spine across studies and sites within and outside of BACPAC studies.

Background Staphylococcus aureus is a global pathogen that is frequently responsible for healthcare-associated infections, including surgical site infections (SSIs). Current infection prevention and control approaches may be limited, with S. aureus antibiotic resistance remaining problematic. Thus, a vaccine to prevent or reduce S. aureus infection is critically needed. We evaluated the efficacy and safety of an investigational 4-antigen S. aureus vaccine (SA4Ag) in adults undergoing elective open posterior spinal fusion procedures with multilevel instrumentation. Methods In this multicenter, site-level, randomized, double-blind trial, patients aged 18–85 years received a single dose of SA4Ag or placebo 10–60 days before surgery. SA4Ag efficacy in preventing postoperative S. aureus bloodstream infection and/or deep incisional or organ/space SSIs was the primary end point. Safety evaluations included local reactions, systemic events, and adverse events (AEs). Immunogenicity and colonization were assessed. Results Study enrollment was halted when a prespecified interim efficacy analysis met predefined futility criteria. SA4Ag showed no efficacy (0.0%) in preventing postoperative S. aureus infection (14 cases in each group through postoperative day 90), despite inducing robust functional immune responses to each antigen compared with placebo. Colonization rates across groups were similar through postoperative day 180. Local reactions and systemic events were mostly mild or moderate in severity, with AEs reported at similar frequencies across groups. Conclusions In patients undergoing elective spinal fusion surgical procedures, SA4Ag was safe and well tolerated but, despite eliciting substantial antibody responses that blocked key S. aureus virulence mechanisms, was not efficacious in preventing S. aureus infection.

Background The use of so-called "red flags" may be beneficial in identifying patients with metastatic spinal disease. This study examined the utility and efficacy of these red flags in the referral chain of patients surgically treated for spinal metastases. Methods The referral chains from the onset of symptoms until surgical treatment for all patients receiving surgery for spinal metastases between March 2009 and December 2020 were reconstructed. The documentation of red flags, as defined by the Dutch National Guideline on Metastatic Spinal Disease, was assessed for each healthcare provider involved. Results A total of 389 patients were included in the study. On average, 33.3% of red flags were documented as present, 3.6% were documented as absent, and 63.1% were undocumented. A higher rate of red flags documented as present was associated with a longer time to diagnosis, but a shorter time to definitive treatment by a spine surgeon. Moreover, red flags were documented as present more often in patients who developed neurological symptoms at any point during the referral chain than those who remained neurologically intact. Conclusions The association of red flags with developing neurological deficits highlights their significance in clinical assessment. However, the presence of red flags was not found to decrease delays prior to referral to a spine surgeon, indicating that their relevance is currently not sufficiently recognized by healthcare providers. Raising awareness of symptoms indicative of spinal metastases may expedite timely (surgical) treatment and thus improve treatment outcome. [ABSTRACT FROM AUTHOR]

The article presents a case study which detected typical vertebral changes in a 52-year-old woman who had palmoplantar pustulosis, using tomosynthesis. Topics discussed include uniqueness of the spinal involvement of SAPHO syndrome, findings on tomosynthesis, and changes that were almost undetectable in plain radiographs.

Advancements in technology and multidisciplinary management have revolutionized the treatment of spinal metastases. Imaging plays a pivotal role in determining the treatment course for spinal metastases. This article aims to review the relevant imaging findings in spinal metastases from the perspective of the treating clinician, describe the various treatment options, and discuss factors influencing choice for each available treatment option. Cases that once required radical surgical resection or low-dose conventional external beam radiation therapy, or both, are now being managed with separation surgery, spine stereotactic radiosurgery/stereotactic body radiation therapy, or both, with decreased morbidity, improved local control, and more durable pain control. The primary focus in determining treatment choice is now on tumor control outcomes, treatment-related morbidity, and quality of life. [ABSTRACT FROM AUTHOR]

Symptomatic cervical spondylosis is a progressive degenerative condition of the cervical spine commonly resulting in functionally-limiting pain, weakness, and/or limited dexterity. Symptomatic cervical spondylosis is believed to occur at higher rates in military aviators than civilian counterparts and is a disqualifying condition for all Navy and Marine Corps aircrew. This condition is non-waiverable for tactical jet (ejection-seat-based) aviators. Medical attrition of experienced tactical jet aircrew from the military aviation community results in substantial cost to the U.S. Government, reduces fleet combat capability, and adversely impacts career progression and retention. The clinical maturation of cervical total disc replacement (TDR) technology over the last 2 decades has revolutionized the treatment of symptomatic cervical spondylosis and enabled a return to duty for hundreds of military service members in non-aviation fields. TDR studies demonstrate equal or superior functional outcomes, rates of symptom resolution, reduced complication and reoperation rates, and lower long-term cost compared to traditional Anterior Cervical Discectomy and Fusion (ACDF). Although initial computational modeling studies have evaluated cervical arthroplasty performance during rotary-wing crash impacts, safety within the dynamic tactical jet environment has not yet been established. The purpose of this article is to review factors relevant to TDR safety and outcomes and to propose a framework to evaluate the safety of TDR in Navy and Marine Corps tactical jet aircrew, to ultimately inform aeromedical algorithms regarding return to flight after TDR.

Objectives Little is known with certainty about the natural history of spinal disease progression in ankylosing spondylitis (AS). Our objective was to discover if there were distinct patterns of change in vertebral involvement over time and to study associated clinical factors. Methods Data were analysed from the Prospective Study of Outcomes in Ankylosing Spondylitis (PSOAS) observational cohort. All patients met modified New York Criteria for AS and had ≥2 sets of radiographs scored by modified Stoke Ankylosing Spondylitis Spinal Score (mSASSS) by two independent readers between 2002 and 2017. Group-based trajectory modelling (GBTM) was used to classify patients into distinct groups of longitudinal mSASSS considering sociodemographic and clinical covariables. The optimal trajectory model and number of trajectories was selected using Nagin's Bayesian information criterion (BIC). Results A total of 561 patients with 1618 radiographs were analysed. The optimum number of trajectory groups identified was four (BIC −4062). These groups were subsequently categorized as: non-progressors (204 patients), late-progressors (147 patients), early-progressors (107 patients) and rapid-progressors (103 patients). Baseline predictors associated with higher spinal disease burden groups included: baseline mSASSS, male gender, longer disease duration, elevated CRP and smoking history. In addition, time-varying anti-TNF use per year was associated with decreased mSASSS progression only in the rapid-progressor group. Conclusions GBTM identified four distinct patterns of spinal disease progression in the PSOAS cohort. Male gender, longer disease duration, elevated CRP and smoking were associated with higher spinal disease groups. Independent confirmation in other AS cohorts is needed to confirm these radiographic patterns. [ABSTRACT FROM AUTHOR]

Objective: Chronic low back pain (CLBP) is a disabling and costly condition for older adults that is difficult to properly classify and treat. In a cohort study, a subgroup of older adults with CLBP who had elevated hip pain and hip muscle weakness was identified; this subgroup differentiated itself by being at higher risk for future mobility decline. The primary purpose of this clinical trial is to evaluate whether a hip-focused low back pain (LBP) treatment provides better disability and physical performance outcomes for this at-risk group compared with a spine-focused LBP treatment. Methods: This study is a multisite, single-blinded, randomized controlled, parallel arm, Phase II trial conducted across 3 clinical research sites. A total of 180 people aged between 60 and 85 years with CLBP and hip pain are being recruited. Participants undergo a comprehensive baseline assessment and are randomized into 1 of 2 intervention arms: hip-focused or spine-focused. They are treated twice weekly by a licensed physical therapist for 8 weeks and undergo follow-up assessments at 8 weeks and 6 months after randomization. Primary outcome measures include the Quebec Low Back Disability Scale and the 10-Meter Walk Test, which are measures of self-report and performance-based physical function, respectively. Impact: This multicenter, randomized clinical trial will determine whether a hip-focused or spine-focused physical therapist intervention results in improved disability and physical performance for a subgroup of older adults with CLBP and hip pain who are at increased risk of mobility decline. This trial will help further the development of effective interventions for this subgroup of older adults with CLBP. [ABSTRACT FROM AUTHOR]

Objectives PsA is characterized by enthesitis, synovitis and osseous involvement in the peripheral and axial joints. Few studies have examined axial involvement in PsA using imaging techniques. Here we examined axial involvement in PsA patients using MRI. In addition, we determined the efficacy of 24 week adalimumab treatment in improving the MRI findings of spondylitis and sacroiliitis. Methods This was a prospective, open-label, single-arm study in patients with PsA. Adalimumab was administered to patients for a total of 24 weeks. MRI examinations were conducted at baseline and at week 24 of adalimumab treatment. Results Thirty-seven patients with PsA were included in this study. Spondylitis was observed in at least one site of the positive scan in 91% (n  = 31) of patients with PsA. The number of arthritic sites in the cervical, thoracic and lumbar regions of the spine was 48, 67 and 53, respectively. All patients had MRI-determined sacroiliitis of grade ≥1 severity while 28 patients (82%) had grade ≥2 sacroiliitis in at least one sacroiliac region. Sacroiliac arthritis was statistically more severe on the right side than on the left side (P  < 0.05). In 34 patients with PsA, the thoracic spine was the most common site of spondylitis. In addition, 24 week adalimumab treatment led to an improvement in the mean number of spondylitis sites and the mean grade of sacroiliitis. Conclusion Treatment with adalimumab for 24 weeks resulted in improvement in spondylitis and sacroiliitis. [ABSTRACT FROM AUTHOR]

Objective 1) To describe a simplified multidisciplinary grading system for the most clinically relevant lumbar spine degenerative changes. 2) To measure the inter-reader variability among non-radiologist spine experts in their use of the classification system for interpretation of a consecutive series of lumbar spine magnetic resonance imaging (MRI) examinations. Methods ATS multidisciplinary and collaborative standardized grading of spinal stenosis, foraminal stenosis, lateral recess stenosis, and facet arthropathy was developed. Our institution's picture archiving and communication system was searched for 50 consecutive patients who underwent non-contrast MRI of the lumbar spine for chronic back pain, radiculopathy, or symptoms of spinal stenosis. Three fellowship-trained spine subspecialists from neurosurgery, orthopedic surgery, and physiatry interpreted the 50 exams using the classification at the L4–L5 and L5–S1 levels. Inter-reader agreement was assessed with Cohen's kappa coefficient. Results For spinal stenosis, the readers demonstrated substantial agreement (κ  = 0.702). For foraminal stenosis and facet arthropathy, the three readers demonstrated moderate agreement (κ  = 0.544, and 0.557, respectively). For lateral recess stenosis, there was fair agreement (κ  = 0.323). Conclusions A simplified universal grading system of lumbar spine MRI degenerative findings is newly described. Use of this multidisciplinary grading system in the assessment of clinically relevant degenerative changes revealed moderate to substantial agreement among non-radiologist spine physicians. This standardized grading system could serve as a foundation for interdisciplinary communication. [ABSTRACT FROM AUTHOR]

The term 'vacuum phenomenon' (VP), is characterized by gas-like density areas due to a rapid increase in the joint space volume ('acute VP') or represent a chronic gas collection. It can occur within a collapsed vertebral body, the spinal canal, joints but mainly the intervertebral disc. Studies support that VP is originated by a dynamic process involving the balance between tissues' liquid and gaseous components, influenced by the duration and the depth of mechanical and metabolic alterations, by the nature of neighboring tissues and the variability in both pressure and permeability of disc or vertebral or joint structures. Prevalence of VP in the general population is about 2%, reaching 20% in the elderly with disc degeneration. Although it's often a random finding in asymptomatic patients, VP is an eventually painful expression of disc degeneration, or disc or vertebral fracture, or bone lesions. In sporadic cases, intradiscal gas can be expelled (all-in-one or gradually), resulting in a gaseous cyst, causing pain and neurological symptoms. Considering that spontaneous resolution and recurrence after surgery are both possible, most of the authors recommend conservative treatment in patients with intradiscal and intravertebral VP; occasionally percutaneous CT(computed tomography) -guided aspiration or vertebral stabilization.

The article describes the case of a 75-year-old male with degenerative joint disease status-post T12-15 fusion five years ago presented with new-onset left lower extremity weakness. Topics discussed include findings on physical examination, fibrocartilaginous tissue fragments with degenerative changes and deposition of positively birefringent crystals revealed in histopathology, and recommendation for clinicians when radiographic evidence seems to contradict.

Introduction: Cervical disc arthroplasty (CDA), a motion-preserving alternative to anterior cervical discectomy and fusion (ACDF), is used in military patients for the treatment of disorders such as spondylosis. Since 2007, the FDA has approved eight artificial discs. The objective of this study is to compare the biomechanics after ACDF and CDA with two FDA-approved devices of differing designs under head and head supported mass loadings.Materials and Methods: A previously validated osteoligamentous C2-T1 finite element model was used to simulate ACDF and two types of CDA (Bryan and Prodisc C) at the C5-C6 level. The hybrid loading protocol associated with in vivo head and head supported mass was used to apply flexion and extension loading. First, intact spine was subjected to 2 Nm of flexion extension and the range of motion (ROM) was measured. Next, for each surgical option, flexion-extension moments duplicating the same ROM as the intact spine were determined. Under these surgery-specific moments, ROM and facet force were obtained at the index level, and ROM, facet force, and intradiscal pressure at the rostral and caudal adjacent levels.Results: ACDF led to increased motion, force and pressures at the adjacent levels. Prodisc C led to increased motion and facet force at the index level, and decreased motion, facet force, and intradiscal pressure at both adjacent levels. Bryan produced less dramatic biomechanical alterations compared with ACDF and Prodisc C. Numerical results are given in the article.Conclusions: Recognizing that ROM is a clinical measure of spine stability/performance, CDA demonstrates a more physiological biomechanical response than ACDF, although the exact pattern depends on the implant design. Anterior and posterior column load-sharing patterns were different between the two implants and may affect implant selection based on the anatomical and pathological state at the index and adjacent levels.

Metastatic spine disease occurs in more than 10% of all cancer patients. Advances in systemic treatment for cancer has led to improved overall survival for many types of cancer, which has increased the overall incidence of spinal metastases. The most common presenting complaint of patients with spinal metastases is pain. Pain originating from spinal metastases can be oncological, mechanical, and/or neurological in nature. Early recognition of these symptoms is helpful to guide treatment and accurately gauge patient prognosis. Unfortunately, the prevalence of degenerative back pain in the general population can complicate early clinical recognition of patients with metastatic spine disease. Therefore, back pain in any patient with a history of malignancy should prompt clinicians to perform an expedited workup for metastatic disease of the spine. Diagnostic imaging and laboratory studies are part of the initial work up. Obtaining pathology via biopsy to establish tumor histology is essential to determine the appropriate treatment.

Spine tumors may arise within or surrounding the spinal cord and/or vertebral column. Spinal tumors can be benign or malignant. Based on their epicenter, they may be classified as intradural-intramedullary, intradural-extramedullary, or extradural. Of these, extradural lesions are the most common, and are typically metastatic. Primary bone tumors of the spinal column comprise 5% of all primary skeletal tumors. The majority of primary spinal column tumors are benign, with malignant tumors comprising only 20%. Overall, spine metastases are the most common malignant spine tumor, and these usually arise from primaries such as lung, breast, and prostate cancers. The advent of improved systemic therapies leading to improved survival and the frequent use of imaging has positioned metastatic spine disease as the new epidemic in oncology. For spine tumors, establishing the correct diagnosis is heavily reliant on magnetic resonance imaging and histological confirmation. In this review, we will provide an overview of the epidemiology, radiological and histopathological features, and the natural history of key primary (benign and malignant) spinal cord and column tumors and metastatic spine tumors. Treatment principles for primary spinal cord or column tumors are aimed toward curative resection, whereas palliative resection forms the treatment principle for most metastatic tumors.

In the past 2 decades, a deeper understanding of the cancer molecular signature has resulted in longer longevity of cancer patients, hence a greater population, who potentially can develop metastatic disease. Spine metastases (SM) occur in up to 70% of cancer patients. Familiarizing ourselves with the key aspects of initial symptom-directed management is important to provide SM patients with the best patient-specific options. We will review key components of initial symptoms assessment such as pain, neurological symptoms, and spine stability. Radiographic evaluation of SM and its role in management will be reviewed. Nonsurgical treatment options are also presented and discussed, including percutaneous procedures, radiation, radiosurgery, and spine stereotactic body radiotherapy. The efforts of a multidisciplinary team will continue to ensure the best patient care as the landscape of cancer is constantly changing. [ABSTRACT FROM AUTHOR]

Background Cervical medial branch radiofrequency ablation (CMBRFA) is an effective treatment for facetogenic pain in patients selected by Spine Intervention Society (SIS) guidelines of 100% symptom improvement with dual medial branch blocks (MBBs) ± placebo block. Patient selection for CMBRFA using ≥80% symptom improvement after dual concordant MBBs is common; however, this has not been studied. Objective To evaluate the effectiveness of CMBRFA and compare outcomes in individuals selected by 80–99% vs 100% symptom improvement with dual concordant MBBs. Design Cross-sectional cohort study. Methods Medical records of 87 consecutive patients were reviewed; 50 met inclusion criteria. A standardized telephone survey was performed at six or more months post-CMBRFA to query numerical rating scale (NRS) pain and patient global impression of change (PGIC) scores. The primary outcomes were the proportion of patients reporting ≥50% reduction of index pain. Results At a mean follow-up time of 16.9 ± 12.7 months, 54% (95% confidence interval [CI] = 35–73%) and 54% (95% CI = 32–74%) of the 80–99% and 100% MBBs groups, respectively, reported ≥50% pain reduction. Between-group comparison showed a relative risk of 0.99 (95% CI = 0.59–1.66) for meeting the primary outcome. Seventy percent (95% CI = 56–81%) of patients reported a PGIC score consistent with "improved or very much improved" at follow-up. Conclusions CMBRFA is an effective treatment in patients who report ≥80% symptom relief with dual concordant MBBs. The present study demonstrated an overall ≥50% pain reduction rate of 54% and no significant difference between those selected by 80–99% vs 100% symptom relief with dual concordant MBBs.

Objective Chronic pain (CP) may increase the risk for major adverse cardiac and cerebrovascular events (MACCEs); however, this issue is still unclear in the Asian population. We conducted this study to delineate it. Design From the Taiwan National Health Insurance Research Database, we identified 17,614 participants (<65 years) with CP and matched them by age and sex at a 1:2 ratio to participants without CP, who made up the comparison cohort. Several causes of CP and its underlying comorbidities were also analyzed. Outcome Measure A comparison of MACCE occurring in the two cohorts was performed via follow-up until 2015. Results The mean age (SD) was 50.2 (11.5) years and 50.4 (11.7) years in participants with and without CP, respectively. In both cohorts, the percentage of female participants was 55.5%. Common causes of CP were spinal disorders (23.9%), osteoarthritis (12.4%), headaches (11.0%), gout (10.2%), malignancy (6.2%), and osteoporosis (4.5%). After adjusting for hypertension, diabetes, chronic obstructive pulmonary disease, renal diseases, hyperlipidemia, liver diseases, dementia, and depression, participants with CP had a higher risk for MACCE than those without CP (adjusted hazard ratio [AHR] = 1.3, 95% confidence interval [CI] = 1.3 − 1.4). After conducting subgroup analyses, an increased risk was also found for all-cause mortality (AHR = 1.4, 95% CI = 1.1 − 1.8), acute myocardial infarction (AHR = 1.2, 95% CI = 1.0 − 1.4), and stroke (AHR = 1.3, 95% CI = 1.3 − 1.4). Conclusions CP is associated with increased occurrence of MACCE. Early detection and interventions for CP are suggested. [ABSTRACT FROM AUTHOR]

Background Patient-reported outcomes (PROs) have been touted as the ultimate assessment of quality medical care and have been proposed as performance measures after appropriate risk adjustment. Although spine conditions represent the most common orthopedic disorders, the most used PROs for disabilities related to the back and neck—the Modified Low Back Pain Disability Questionnaire (MDQ) and the Neck Disability Index (NDI)—have not been evaluated as performance measures. Objective The objective of this study was to benchmark physical therapists' performance in the management of spine conditions not involving surgery through the use of risk-adjusted MDQ and NDI outcomes. Design This was a retrospective observational study. Methods Data were accessed for patients seeking physical therapy with no history of related surgery for back or neck pain (315,274 treatment episodes) between January 2015 and June 2018. Patients with complete data, including initial and matched final MDQ or NDI, were considered for analysis (182,276 patients; 2799 physical therapists). Linear models controlling for baseline PRO and patient characteristics predicted PRO change for each patient. An aggregated performance ratio of actual PRO change to predicted PRO change was calculated for each physical therapist, and then empirical bootstrapping was used to develop the median performance ratio and its confidence intervals. Physical therapists who met a 40-patient threshold for either cohort (MDQ or NDI) were classified as "outperforming," "meeting expectations," or "underperforming" relative to predicted values using these 95% confidence intervals. Results Performance ratios indicated that 10% and 11% of physical therapists outperformed, 79% and 78% met expectations, and 11% and 11% underperformed relative to the risk-adjusted predicted change in the MDQ (1240 therapists; 97,908 patients) and NDI (461 therapists; 26,123 patients), respectively. To demonstrate the clinical importance of risk adjustment, clinical performance was evaluated in the seemingly homogeneous subset of 208 physical therapists within 0.5 SD of the median baseline MDQ and the median actual change in the MDQ. Following risk adjustment, 2 physical therapists were classified in each of the outperforming and underperforming cohorts. Limitations The secondarily obtained observational data used were not collected for research purposes. Additionally, the analyses were limited by missing baseline information and follow-up PROs. Conclusions The risk-adjusted performance ratios for the MDQ and NDI resulted in disparate conclusions regarding the quality of care compared with the raw, unadjusted change scores. According to the baseline and unadjusted change in the MDQ, even physical therapists in the most homogeneous sample were differentiated following appropriate risk adjustment. Clinically important improvements in actual PROs were observed in the outperforming but not in the underperforming physical therapists. Clinically meaningful differences in the performance ratio are unknown and are a limitation to clinical application and an opportunity for future research. [ABSTRACT FROM AUTHOR]

Bones are the third most common site for cancer metastases, and the axial skeleton is the most frequent skeletal location. In a postmortem study, bone metastases were reported in 70% of breast and prostate cancer patients. Bone metastases from breast, lung, prostate, thyroid, and kidney cancers account for 80% of all bone metastases. Bone lesions exist in 60% of newly diagnosed multiple myeloma patients. With increasing numbers of people who have survived cancer, many patients with cancer and axial skeletal bony metastases will be seen by physical and occupational therapists. Guidelines are lacking on how to perform physical examinations and provide exercise programs for these patients without compromising the diseased spine. In this article, we discuss the available evidence for similar spinal conditions, the biomechanics of spinal load, and changes associated with posture and weight load. We provide recommendations on how to assess a patient's strength, how to strengthen without compromising the diseased spine, and how to teach patients to use correct body mechanics during mobility and activities of daily living.

Background Back pain is a very prevalent complaint, affecting two-thirds of the US population, and it accounts for $100 billion annually in health care expenditures. The occurrence of depression has been reported in existing literature among patients with back pain, but there is limited information regarding health care expenditures among patients with back pain and concurrent depression. Objective To assess excess total and subtypes of health care expenditures among adults with spondylosis, intervertebral disc disorders, and other back problems who reported having depression compared with those without depression in the United States. Methods We utilized a cross-sectional design, pooling Medical Expenditure Panel Survey data from 2010–2012. The eligible study sample included adults (age ≥18 years) who reported positive health care expenditure. Total and subtypes of health care expenditures constituted the dependent variable. Ordinary least squares (OLS) regressions on logged expenditures were performed. Four models were developed to assess influence of demographics, functional ability, and concurrent diagnoses on health care expenditures. Results A total of 6,739 adults with spondylosis, intervertebral disc disorders, and other back problems were assessed, 20.2% (N = 1,316) of whom had concurrent depression. Adults with concurrent depression had significantly higher total health care expenditures ($13,153) compared with the nondepression group ($7,477, P  < 0.001). Outpatient and prescription expenditures showed similar findings. After adjusting for demographics, functional disabilities, and comorbidities, excess cost remained higher in the group reporting concurrent depression (46%). Conclusions This study demonstrates that the presence of depression in adults with spondylosis, intervertebral disc disorders, and other back problems is associated with greater economic burden. These findings remained consistent after adjusting for all independent sets of variables. The study's findings suggest that interventions resulting in better management of depression have the potential to significantly reduce the economic burden in this population. [ABSTRACT FROM AUTHOR]

Objective Lumbar spinal stenosis (LSS) is a degenerative spinal condition affecting nearly 50% of patients presenting with lower back pain. The goal of this review is to present and summarize the current data on how LSS presents in various populations, how it is diagnosed, and current therapeutic strategies. Properly understanding the prevalence, presentation, and treatment options for individuals suffering from LSS is critical to providing patients the best possible care. Results The occurrence of LSS is associated with advanced age. In elderly patients, LSS can be challenging to identify due to the wide variety of presentation subtleties and common comorbidities such as degenerative disc disease. Recent developments in imaging techniques can be useful in accurately identifying the precise location of the spinal compression. Treatment options can range from conservative to surgical, with the latter being reserved for when patients have neurological compromise or conservative measures have failed. Once warranted, there are several surgical techniques at the physician's disposal to best treat each individual case. [ABSTRACT FROM AUTHOR]

Objectives The aim of our study was to ascertain the underlying role of microRNAs (miRNAs) in human intervertebral disc degeneration (IDD). Design Bioinformatic analysis from multiple databases. Methods Studies of the association of miRNAs and IDD were identified in multiple electronic databases. All potential studies were assessed by the same inclusion and exclusion criteria. We recorded whether miRNA expression was commonly increased or suppressed in the intervertebral disc tissues and cells of IDD subjects. We used String to identify biological process and cellular component pathways of differentially expressed genes. Results We included fifty-seven articles from 1,277 records in this study. This report identified 40 different dysregulated miRNAs in 53 studies, including studies examining cell apoptosis (26 studies, 49.06%), cell proliferation (15 studies, 28.3%), extracellular matrix (ECM) degradation (10 studies, 18.86%), and inflammation (five studies, 9.43%) in IDD patients. Three upregulated miRNAs (miR-19b, miR-32, miR-130b) and three downregulated miRNAs (miR-31, miR-124a, miR-127-5p) were considered common miRNAs in IDD tissues. The top three biological process pathways for upregulated miRNAs were positive regulation of biological process, nervous system development, and negative regulation of biological process, and the top three biological process pathways for downregulated miRNAs were negative regulation of gene expression, intracellular signal transduction, and negative regulation of biological process. Conclusions This study revealed that miRNAs could be novel targets for preventing IDD and treating patients with IDD by regulating their target genes. These results provide valuable information for medical professionals, IDD patients, and health care policy makers. [ABSTRACT FROM AUTHOR]

A case study is presented of a 69-year-old man with Adult degenerative scoliosis (ADS), hypertension, and chronic bronchitis presented with chronic progressive lower thoracic and lumbar pain and right anterior thigh pain and paresthesias. It mentions his treatments including oral analgesics, physical therapy, and spinal injections.

Background Prehabilitation programs have led to improved postoperative outcomes in several surgical contexts, but there are presently no guidelines for the prehabilitation phase before lumbar fusion surgery. Objective The objective was to investigate whether a person-centered physical therapy prehabilitation program, based on a cognitive-behavioral approach, is more effective than conventional care in reducing disability and improving functioning after lumbar fusion surgery in patients with degenerative disk disease. Design This study was a randomized controlled trial. Setting The study took place at 2 private spine clinics and 1 university hospital. Patients We prospectively enrolled 118 patients scheduled for lumbar fusion surgery. Intervention The active intervention used a person-centered perspective and focused on promoting physical activity and targeting psychological risk factors before surgery. The control group received conventional preoperative care. Measurements The primary outcome was the Oswestry Disability Index score. Secondary outcomes were back and leg pain intensity, catastrophizing, kinesiophobia, self-efficacy, anxiety, depression, health-related quality of life, and patient-specific functioning, physical activity, and physical capacity. Data were collected on 6 occasions up to 6 months postoperatively. A linear mixed model was used to analyze the change scores of each outcome. Results No statistically significant between-group difference was found on the primary outcome (disability) over time (baseline to 6 months). Among secondary outcome measures, a statistically significant interaction effect ("Group × Time") was seen for the European Quality of Life 5 Dimensions Questionnaire. The largest between-group difference on the European Quality of Life 5 Dimensions Questionnaire index was seen 1 week prior to surgery and favored the active intervention. The largest between-group effect sizes at the 6-month follow-up favored the active intervention, and were seen for physical activity intensity, steps per day, and the One Leg Stand Test. Both groups reached the minimal important change for the primary outcome and, in several secondary outcomes (pain intensity, back and leg; pain catastrophizing; anxiety; health-related quality of life [EQ5D VAS]), already at 8-week follow-up. Limitations The participants' preoperative level of disability was lower than normative values, which suggests selection bias. Conclusions Both interventions led to clinically important changes, but it is not clear what kind of prehabilitation program is the most effective. [ABSTRACT FROM AUTHOR]

Objective Although anti-inflammatory drugs are commonly used in acute discogenic sciatica, data regarding their efficacy are scarce and controversial. We compared the efficacy and safety of intravenous ketoprofen and methylprednisolone with placebo in sciatica. Design Multicenter, double-blinded randomized controlled trial. Subjects Patients with confirmed discogenic acute sciatica, without neurologic deficit, were randomized into three arms. Methods Besides standard-of-care analgesic therapy, they received intravenous injections of methylprednisolone (60 mg/d) or ketoprofen (200 mg/d) or placebo for five days. The primary outcome was leg pain over five days. Secondary outcomes were clinical responses at days 3 and 5, lumbar pain, Straight Leg Raise Test and lumbar flexion index, analgesic consumption, realization of lumbar spine injections, and surgery during the study period. Results Fifty-four patients were randomized, and 50 completed the study. In patients admitted to the hospital for pain control with acute lumbar radicular pain due to intervertebral disc herniation and receiving an oral analgesic protocol including paracetamol, nefopam, tramadol, and morphine, there was no additional analgesic effect seen between groups. There was no significant difference in leg pain between the three groups over the study period. In the methylprednisolone group, however, we observed a higher rate of clinically relevant responses at day 3. No difference was observed on other secondary efficacy outcomes and safety. Conclusion No significant difference in leg pain was observed between groups. However, there was a higher proportion of patients relieved with intravenous methylprednisolone at day 3, compared with ketoprofen or placebo. [ABSTRACT FROM AUTHOR]

Introduction: Back pain related to spinal degenerative disease is one of the most common causes of missed duty days and medical separation for active service members. While the topic of operative versus non-operative treatment of degenerative spine conditions in active military personnel has received more and much needed attention in the last few years, there remains a paucity of data examining the expanded demographics and clinical findings of those undergoing spinal fusion in which validated outcome measures are used to assess post-operative results. The purpose of this study was to define the characteristics and outcomes of spinal fusion surgery at U.S. military medical treatment facilities.Materials and Methods: A cohort of 145 active military personnel undergoing spinal fusion at a single military medical center between 2008 and 2013 were examined in a retrospective fashion using data from primary source documentation recorded prospectively in the military electronic medical records and the image data repository for demographics, clinical/imaging findings and patient reported outcome scores at mean follow-up of 6 mo. Oswestery Disability Index (ODI) scores and the Visual Analog Scale (VAS) were used as patient reported outcome measures. Soldier rank, active duty status, and service-connected disability percentage were also analyzed as military specific outcome measures.Results: The typical solider undergoing spinal fusion was a Caucasian male serving in the U.S. Army. At last follow-up, there were statistically significant improvements in pre-operative to post-operative ODI and VAS scores. Younger age at the time of surgery was a negative predictor for post-operative VAS outcomes (p = 0.047). There were six reoperations in the cohort for neurologic symptoms and hardware migration. The majority of soldiers went on to medical retirement but a considerable number saw an increase in their rank prior to doing so. Those who ended their service in regular retirement and medical retirement went on to see 90.7% and 85% service-connected disability respectively.Discussion: This investigation reports on the largest cohort of active military personnel undergoing spinal fusion. A variety of demographic information are reviewed to clarify the picture of soldiers at risk for needing a spinal fusion. While younger age was an independent risk factors for worsened VAS scores, no independent variable portended a worse ODI score at last follow-up. Despite improvements in objective measures such as VAS, ODI, and increases in rank, soldiers going on to retirement collected a dramatic service-connected disability percentage.Level of Evidence: Level IV, Therapeutic.

Objective To assess the effect depression has on outcomes after cervical epidural steroid injections (CESIs). Design Retrospective review of a prospectively collected database. Setting Single institution tertiary care center. Subjects Fifty-seven patients with cervical spondylosis and cervical radicular pain who were deemed appropriate surgical candidates but elected to undergo CESI first were included. Methods Twenty-one of 57 (37%) patients with depression (defined as Zung Depression Scale >33) were included. Patient-reported outcomes including Neck Disability Index (NDI), numeric rating scale (NRS) for arm pain (AP), NRS for neck pain (NP), and EuroQol-5D (EQ-5D) were collected at baseline and three-month follow-up. Minimal clinically important differences were then calculated to provide dichotomous outcome measures of success. Results Overall, 24 and 28 patients achieved at least 50% improvement in AP and NP, respectively. In terms of disability, 25/57 (43.9%) patients achieved >13.2-point improvement on the NDI overall. In patients with depression, 4/21 (19.0%) and 5/21 (23.8%) achieved at least 50% improvement on the NRS for AP and NP, respectively, compared with 20/36 (55.5%) and 23/36 (63.8%) in patients without depression. This difference was statistically significant for both pain measures (P  < 0.002 AP, P  < 0.006 NP). Statistically fewer patients, 5/21 (24%), with depression achieved ≥13.2-point improvement on the NDI compared with 20/36 (55%) nondepressed patients (P  < 0.01). There was no difference in outcomes between groups on the EQ-5D. Conclusions Patients with cervical spondylosis and comorbid depression who undergo CESI are less likely to achieve successful outcomes in both pain and function compared with nondepressed patients at three months.

We recently reported the potential of Hough transform in delineating spinal cord metabolism by 18F-fluorodeoxyglucose PET/CT scanning in amyotrophic lateral sclerosis. The present study aimed to verify the relationship between spinal cord and brain metabolism in 44 prospectively recruited patients affected by amyotrophic lateral sclerosis submitted to 18F-fluorodeoxyglucose brain and whole-body PET/CT. Patients were studied to highlight the presence of brain hypo- or hypermetabolism with respect to healthy controls, and multiple regression analysis was performed to evaluate the correlation between spinal cord and brain metabolism. Our results confirmed higher 18F-fluorodeoxyglucose uptake in both cervical and dorsal spinal cord in patients with amyotrophic lateral sclerosis with respect to controls. This finding was paralleled by the opposite pattern in the brain cortex that showed a generalized reduction in tracer uptake. This hypometabolism was particularly evident in wide regions of the frontal-dorsolateral cortex while it did not involve the midbrain. Bulbar and spinal disease onset was associated with similar degree of metabolic activation in the spinal cord. However, among spinal onset patients, upper limb presentation was associated with a more pronounced metabolic activation of cervical segment. Obtained data suggest a differential neuro-pathological state or temporal sequence in disease progression. [ABSTRACT FROM AUTHOR]

X-linked adrenoleukodystrophy is caused by ATP-binding cassette transporter D1 (ABCD1) mutations and manifests by default as slowly progressive spinal cord axonopathy with associated demyelination (adrenomyloneuropathy). In 60% of male cases, however, X-linked adrenoleukodystrophy converts to devastating cerebral inflammation and demyelination (cerebral adrenoleukodystrophy) with infiltrating blood-derived monocytes and macrophages and cytotoxic T cells that can only be stopped by allogeneic haematopoietic stem cell transplantation or gene therapy at an early stage of the disease. Recently, we identified monocytes/macrophages but not T cells to be severely affected metabolically by ABCD1 deficiency. Here we found by whole transcriptome analysis that, although monocytes of patients with X-linked adrenoleukodystrophy have normal capacity for macrophage differentiation and phagocytosis, they are pro-inflammatory skewed also in patients with adrenomyloneuropathy in the absence of cerebral inflammation. Following lipopolysaccharide activation, the ingestion of myelin debris, normally triggering anti-inflammatory polarization, did not fully reverse the pro-inflammatory status of X-linked adrenoleukodystrophy macrophages. Immunohistochemistry on post-mortem cerebral adrenoleukodystrophy lesions reflected the activation pattern by prominent presence of enlarged lipid-laden macrophages strongly positive for the pro-inflammatory marker co-stimulatory molecule CD86. Comparative analyses of lesions with matching macrophage density in cases of cerebral adrenoleukodystrophy and acute multiple sclerosis showed a similar extent of pro-inflammatory activation but a striking reduction of anti-inflammatory mannose receptor (CD206) and haemoglobin-haptoglobin receptor (CD163) expression on cerebral adrenoleukodystrophy macrophages. Accordingly, ABCD1-deficiency leads to an impaired plasticity of macrophages that is reflected in incomplete establishment of anti-inflammatory responses, thus possibly contributing to the devastating rapidly progressive demyelination in cerebral adrenoleukodystrophy that only in rare cases arrests spontaneously. These findings emphasize monocytes/macrophages as crucial therapeutic targets for preventing or stopping myelin destruction in patients with X-linked adrenoleukodystrophy. [ABSTRACT FROM AUTHOR]

Objective. Data on the relationship between disc degeneration (DD) and fragility fractures in men are limited. The aim of this study was to prospectively analyse the risk of vertebral and non-vertebral fractures in men with thoracolumbar DD according to the severity of its radiological signs: disc space narrowing (DSN), osteophytes and endplate sclerosis. Methods. Men >50 years of age (n = 765) had lateral spine radiographs and DXA and were monitored prospectively. We analysed the risk of incident vertebral (7.5 years) and non-vertebral fractures (10 years) in men according to the severity of DD. Results. After adjustment for age and weight, BMD increased with increasing total DSN score, endplate sclerosis and osteophytosis. Over 7.5 years, 28 incident vertebral fractures occurred in 27 men. After adjustment for age, BMI, spine BMD, prior fractures and abdominal aortic calcifications, the vertebral fracture risk was 3-fold higher in the upper DSN quartile vs men without DSN. After adjustment for the same confounders, vertebral fracture risk was also nearly 3-fold higher in the upper DSN quartile vs the three lower quartiles combined. Over 10 years, 61 men sustained non-vertebral fragility fractures. After adjustment for age, BMI, hip BMD, abdominal aortic calcifications and prior falls and fractures, the non-vertebral fracture risk decreased with increasing DSN score. The risk of non-vertebral fracture was half as high in men above the median total DSN score vs men below the median. Conclusion. In older men, severe DD is associated with higher BMD. Multilevel severe DSN is associated with higher vertebral fracture risk and lower non-vertebral fracture risk. [ABSTRACT FROM AUTHOR]

Objective. It has been postulated that local anesthetic administration may be the most painful part of interventional spine procedures. Despite this, there is a lack of evidence supporting the commonly used traditional technique of anesthetic delivery as part of these procedures. This study tested three hypotheses: 1) alternative method of local anesthesia injection is superior to the traditional method; 2) using the traditional method of injection is not superior to using no local anesthetic; and 3) treatment needle size, anesthetic injection technique, and sedation are associated with pain experienced during procedures. Design. Prospective, multicenter clinical trial of 127 participants who underwent elective bilateral symmetric interventional spine procedures in outpatient spine clinics. Methods. Primary outcomes were pain scores during and after procedures to examine the influence of anesthetic injection method and treatment needle gauge on pain experience using linear mixed model regression analysis. A post-hoc comparison of estimated marginal mean pain scores was completed on both anesthetic injection method and treatment needle gauge. Conclusions. The alternative method was superior (P< 0.05) to the traditional method on post procedural pain scores. Injecting local anesthetic with the traditional or alternative method was not superior to using no local anesthetic. Treatment needle size, pain at one inch of treatment needle insertion, and baseline pain were all significantly (P< 0.05) associated with overall procedural pain. Further studies are needed optimize and justify local anesthetic injections for these procedures. [ABSTRACT FROM AUTHOR]

Background: The use of magnetic resonance imaging (MRI) as initial imaging for back pain has increased in general practice. However, few data are available on the characteristics of these referred patients. The objective of this study was to describe the baseline characteristics and MRI findings of patients presenting for a lumbar MRI examination as referred by their GP.Methods: Patients presenting for a lumbar MRI examination as referred by their GP were recruited at the MRI Center. The MRI radiology reports were scored for the presence of disc bulging, disc herniation, nerve root compression, spinal stenosis, spondylolisthesis and serious pathologies. Information on patients' characteristics, characteristics of the complaints and red flags were derived from questionnaires. Cross-sectional differences between patients with and without specific MRI findings were analyzed.Results: A total of 683 low back pain (LBP) patients were included; mean age was 49.9 (range 19-80) years and 53% was male. Mean back pain severity score was 6.6 (SD 2.0) and 67% of the patients reported having chronic LBP. In total, 374 patients (55%) reported sciatica complaints for at least 6 weeks. Of all MRI reports, 69% mentioned signs of nerve root compression. Serious pathologies were reported in 3% of the patients. In total, 94% of patients had abnormal MRI findings.Conclusions: Almost all patients presenting for a lumbar MRI examination as referred by their GP had abnormal MRI findings. In total, 55% of the patients reported persistent sciatica in which imaging is recommended according to international guidelines. [ABSTRACT FROM AUTHOR]

As a tertiary referral centre of spinal surgery, the Royal National Orthopaedic Hospital (RNOH) handles hundreds of spinal cases a year, often with complex pathology and complex care needs. Despite this, issues were raised at the RNOH following lack of sufficient documentation of preoperative and postoperative clinical findings in spinal patients undergoing major surgery. This is not in keeping with guidelines provided by the Royal College of Surgeons. The authors believe that a standardised clerking pro forma for surgical spinal patients admitted to RNOH would improve the quality of care provided. Therefore, the use of a standard clerking pro forma for all surgical spinal patients could be a useful tool enabling improvements in patients care and safety in keeping with General Medical Council/National Institute for Health and Care Excellence guidelines. An audit (with closure of loop) looking into the quality of the preoperative and postoperative clinical documentation for surgical spinal patients was carried out at the RNOH in 2016 (retrospective case note audit comparing preintervention and postintervention documentation standards). Our standardised pro forma allows clinicians to best utilise their time and standardises examination to be compared in a temporal manner during the patients admission and care. It is the authors understanding that this work is a unique study looking at the quality of the admission clerking for surgical spinal patients. Evidently, there remains work to be done for the widespread utilisation of the pro forma. Early results suggest that such a pro forma can significantly improve the documentation in admission clerking with improvements in the quality of care for patients. [ABSTRACT FROM AUTHOR]

Background Non-traumatic acquired spinal deformities represent a separate entity within the axial pathologies in children. Their causes are variable (neurological, muscular, infectious, especially Pott's disease, inflammatory or tumoral). The etiological diagnosis can be clinically oriented by pain, medical history, especially rheumatic. The contribution of the CT scan is crucial, as it localizes the lesion, specifies its nature, but above all it helps the histological diagnosis by guided biopsies. Our case illustrates the difficulties in diagnosing the aetiology of spinal acquired deformity in a girl with a multi-evocative context. Observation A 14 years-old girl complains for a few months of a dorso-lumbar spinal pain and a vicious attitude. Her medical history includes femoral thrombophlebitis and psoriasis. She had no trauma or fever. Clinically, the general state is preserved, with no local inflammatory signs, a kyphotic attitude with an analgesic lumbar support was noted. The rest of the locomotor exam was normal. CT scan shows cancellous body geodes with a double mirror. Discussion Acquired spinal deformities are always secondary to general disease. The fever may point to bacterial infections, especially tuberculosis (Pott's disease), but also non-infectious causes such as a rheumatic disease. For our patient, psoriasis argues for the latter possibility. However, the rarity of isolated disco-vertebral involvement and the severity of the lytic lesions are against this diagnosis. The histopathological exam showed an eosinophilic granuloma, confirming the histiocytosis X diagnosis. The cortico-response strengthen the diagnosis. The course was marked by the bone remodeling with the posture correction. Conclusion A clinical, radiological, and histological analysis allow the etiological orientation in front of acquired spinal deformity. [ABSTRACT FROM AUTHOR]

Background: Prior studies found a range of psychological factors related to the perception of pain, maintenance of pain and disability. Purpose: The aim of this study was to investigate the role of pain fear-avoidance and pain acceptance in chronic pain adjustment. The influence of two diathesis variables (resilience and experiential avoidance) was also analyzed. Methods: The sample was composed of 686 patients with chronic spinal pain. Structural equation modelling analyses were used to test the hypothetical model. Results: Experiential avoidance was associated with pain fear-avoidance, and resilience was strongly associated with pain acceptance. Pain acceptance was negatively associated with negative mood, functional impairment and pain intensity. However, pain fear-avoidance was positively and significantly associated with negative mood but had no association with pain intensity. There was a path from functional impairment to pain fear-avoidance. Conclusions: Resilience and experiential avoidance appear as variables which could explain individual differences in pain experience. [ABSTRACT FROM AUTHOR]

BACKGROUND: Lumbar disk degeneration (LDD) has been related to heavy physical loading. However, the quantification of the exposure has been controversial, and the dose-response relationship with the LDD has not been established. OBJECTIVE: The purpose of this study was to investigate the dose-response relationship between lifetime cumulative lifting load and LDD. DESIGN: This was a cross-sectional study. METHODS: Every participant received assessments with a questionnaire, magnetic resonance imaging (MRI) of the lumbar spine, and estimation of lumbar disk compression load. The MRI assessments included assessment of disk dehydration, annulus tear, disk height narrowing, bulging, protrusion, extrusion, sequestration, degenerative and spondylolytic spondylolisthesis, foramina narrowing, and nerve root compression on each lumbar disk level. The compression load was predicted using a biomechanical software system. RESULTS: A total of 553 participants were recruited in this study and categorized into tertiles by cumulative lifting load (ie, <4.0 × 105, 4.0 × 105 to 8.9 × 106, and ≥8.9 × 106 Nh). The risk of LDD increased with cumulative lifting load. The best dose-response relationships were found at the L5-S1 disk level, in which high cumulative lifting load was associated with elevated odds ratios of 2.5 (95% confidence interval [95% CI]=1.5, 4.1) for dehydration and 4.1 (95% CI=1.9, 10.1) for disk height narrowing compared with low lifting load. Participants exposed to intermediate lifting load had an increased odds ratio of 2.1 (95% CI=1.3, 3.3) for bulging compared with low lifting load. The tests for trend were significant. LIMITATIONS: There is no "gold standard" assessment tool for measuring the lumbar compression load. CONCLUSIONS: The results suggest a dose-response relationship between cumulative lifting load and LDD. [ABSTRACT FROM AUTHOR]
