Worldwide, most spine imaging is either “inappropriate” or “probably inappropriate”. The Choosing Wisely recommendation is “Do not perform imaging for lower back pain unless red flags are present.” There is currently no detailed breakdown of lower back pain diagnostic imaging performed in New Brunswick (NB) to inform future directions. A registry of spine imaging performed in NB from 2011-2019 inclusive (n=410,000) was transferred to the secure platform of the NB Institute for Data, Training and Research (NB-IRDT). The pseudonymized data included linkable institute identifiers derived from an obfuscated Medicare number, as well as information on type of imaging, location of imaging, and date of imaging. The transferred data did not include the radiology report or the test requisition. We included all lumbar, thoracic, and complete spine images. We excluded imaging related to the cervical spine, surgical or other procedures, out-of-province patients and imaging of patients under 19 years. We verified categories of X-ray, Computed Tomography (CT), and Magnetic Resonance Imaging (MRI). Red flags were identified by ICD-10 code-related criteria set out by the Canadian Institute for Health Information. We derived annual age- and sex-standardized rates of spine imaging per 100,000 population and examined regional variations in these rates in NB's two Regional Health Authorities (RHA-A and RHA-B). Age- and sex-standardized rates were derived for individuals with/without red flag conditions and by type of imaging. Healthcare utilization trends were reflected in hospital admissions and physician visits 2 years pre- and post-imaging. Rurality and socioeconomic status were derived using patients’ residences and income quintiles, respectively. Overall spine imaging rates in NB decreased between 2012 and 2019 by about 20% to 7,885 images per 100,000 people per year. This value may be higher than the Canadian average. Females had 23% higher average imaging rate than males. RHA-A had a 45% higher imaging rate than RHA-B. Imaging for red flag conditions accounted for about 20% of all imaging. X-rays imaging accounted for 67% and 75% of all imaging for RHA-A and RHA-B respectively. The proportions were 20% and 8% for CT and 13% and 17% for MRI. Two-year hospitalization rates and rates of physician visits were higher post-imaging. Females had higher age-standardized hospitalization and physician-visit rates, but the magnitude of increase was higher for males. Individuals with red flag conditions were associated with increased physician visits, regardless of the actual reason for the visit. Imaging rates were higher for rural than urban patients by about 26%. Individuals in the lowest income quintiles had higher imaging rates than those in the highest income quintiles. Physicians in RHA-A consistently ordered more images than their counterparts at RHA-B. We linked spine imaging data with population demographic data to look for variations in lumbar spine imaging patterns. In NB, as in other jurisdictions, imaging tests of the spine are occurring in large numbers. We determined that patterns of imaging far exceed the numbers expected for ‘red flag’ situations. Our findings will inform a focused approach in groups of interest. Implementing high value care recommendations pre-imaging ought to replace low-value routine imaging

Numerous studies have demonstrated that concomitant lower back pain (LBP) results in worse functional outcomes in patients undergoing surgical treatment for the management of end stage hip and knee arthritis. However, no equivalent studies have analysed the impact of back pain on the outcomes of patients with end stage ankle arthritis. Furthermore, given that two widely accepted surgical options exist in the treatment of ankle arthritis, namely total ankle arthroplasty (TAA) and ankle arthrodesis (AA), it is possible that one surgical technique may be superior in patients with LBP. The aim of this study was to determine the incidence of LBP in people with ankle arthritis, analyse its effect on functional outcomes, and explore whether there was a treatment advantage from either TAA or AA. Prospectively collected data from the Canadian Orthopaedic Foot and Ankle Society (COFAS) database of ankle arthritis was analysed in this study. All patients with ankle arthritis who underwent surgery performed by three fellowship-trained foot and ankle surgeons at a single institution between January 2003 and July 2012 were studied. Patient demographics were collected pre-operatively, including the absence or presence of back pain, and post-operative follow up was performed at 2 and 5 years, evaluating patient-reported functional outcome measures including the Ankle Arthritis Score (AAS) and the 36-item short form survey (SF-36). Using a linear regression model, a multivariate analysis was performed to examine the relationship between back pain, TAAs and AAs. In total, 451 patients were studied. 164 patients (36.4%) presented with concomitant LBP. At presentation, the LBP group had worse AAS scores (54.8 vs 57.8 p. At 2 years postoperatively, the AAS score was the same in both groups (28.9 vs 26.8 p = 0.3), but patients with LBP had worse SF-36 PCS (42.1 vs 36.6 p 0.05) in any of the functional outcome scores at 2 or 5 years post-operatively. The results of this study suggest there is no advantage of TAA over AA in the treatment of ankle arthritis in patients with concomitant lower back pain. Although pre-operative back pain resulted in worse SF-36 outcomes at 2 and 5 years post- operatively, this was not the case for AAS scores

Low back pain in junior Australian Rules footballers has not been investigated, despite findings that adolescent back pain is a strong predictor for adult back pain. The aim of this study was to determine the prevalence, intensity, quality and frequency of low back pain in junior Australian Rules footballers. A cross-sectional survey of male non-elite junior (n = 60) and elite junior players (n = 102) was conducted along with a convenience sample of non-footballers (school children) (n = 100). Subjects completed a self-reported questionnaire on low back pain incorporating the Quadruple Visual Analogue Scale and McGill Pain Questionnaire (short form), along with additional questions adapted from an Australian epidemiological study. For current, average and best low back pain levels, elite junior players had higher pain levels (p < 0.001), with no difference noted between non-elite juniors and controls for average and best low back pain. For low back pain at worst, there were significant differences in the mean pain cores. The difference between elite juniors and non-elite juniors (p = 0.040) and between elite juniors and controls (p < 0.001) was significant, but not between non-elite juniors and controls. The chance of suffering low back pain increases from 45% for controls, through 55% for non-elite juniors to 66.7% for elite juniors. The chance that a pain sufferer experiences chronic pain is 16% for controls and 41% for non-elite junior and elite junior players. Elite junior players experienced low back pain more frequently (p = 0.002), with no difference in frequency noted between non-elite juniors and controls. Over 25% of elite junior and non-elite junior players reported that back pain impacted their performance some of the time or greater. This study demonstrated that when compared with non-elite junior players and non-footballers of a similar age, elite junior players experience back pain more severely and frequently and have higher prevalence and chronicity rates

To determine the number of patients with low back pain who have low serum Vitamin-D levels in our local population and the clinical efficacy of Vitamin-D supplementation on VAS and MODQ scores. This Prospective cohort study was conducted from 20th March 2016 to 19th March 2017. 600 patients were included in the study who met the inclusion criteria, i.e. patients presenting to the Out Patient Department (OPD) with low back pain for a duration of less than six months aged between 15 to 55 years. Venous blood withdrawn and serum levels of Vitamin-D measured. According to serum Vitamin-D levels, categorized as deficient, sufficient or excess. Those having deficient Vitamin-D levels (< 2 0 ng/dL) were given Vitamin-D supplementation as Oral 50,000 IU Vitamin-D3 daily for 05 days, then once weekly for 08 weeks while those having insufficient levels (20–30 ng/dL) given Oral 50,000 IU Vitamin-D3 once weekly for 08 weeks. Vitamin-D levels, Visual Analog Pain Scale (VAS) and Modified Oswestry Disability Questionnaire (MODQ) scoring done at baseline, 02, 03 and 06 months. Data analyzed using SPSS version 23. Mean age of patients included in the study 44.21 ± 11.92 years. Out of the total, 337 (56.17%) were males and 263 (43.83%) females. Out of the total, 20.67%, 26.17% and 28.83% had mild, moderate and severe Vitamin-D deficiency, respectively. Predominantly patients with severe Vitamin-D deficiency presented in winters (October – February) (17.16%) as compared to other seasons. The most pre-dominant risk factor in patients with low Vitamin-D levels was smoking (21.33%). Mean baseline Vitamin-D levels were 13.32 ± 6.10 ng/dL and after supplementation these levels improved to 37.18 ± 11.72 ng/dL. VAS score improved from a mean baseline value to 81 to 36 at 6 months (p < 0 .01). Likewise, MODQ score decreased from a baseline mean of 46 to 25 at 6 months (p < 0 .01). Vitamin D plays a crucial role in the musculoskeletal framework of the body. The deficiency is more prevalent in the youth due to sedentary lifestyle and indoor preference.

Intervertebral discs (IVDs) degeneration is one of the major causes of back pain. Upon degeneration, the IVDs tissue become inflamed, and this inflammatory microenvironment may cause discogenic pain. Cellular senescence is a state of stable cell cycle arrest in response to a variety of cellular stresses including oxidative stress and adverse load. The accumulation of senescent IVDs cells in the tissue suggest a crucial role in the initiation and development of painful IVD degeneration. Senescent cells secrete an array of cytokines, chemokines, growth factors, and proteases known as the senescence-associated secretory phenotype (SASP). The SASP promote matrix catabolism and inflammation in IVDs thereby accelerating the process of degeneration. In this study, we quantified the level of senescence in degenerate and non-degenerate IVDs and we evaluated the potential of two natural compounds to remove senescent cells and promote overall matrix production of the remaining cells. Human IVDs were obtained from organ donors. Pellet or monolayer cultures were prepared from freshly isolated cells and cultured in the presence or absence of two natural compounds: Curcumin and its metabolite vanillin. Monolayer cultures were analyzed after four days and pellets after 21 days for the effect of senolysis. A cytotoxicity study was performed using Alamar blue assay. Following treatment, RNA was extracted, and gene expression of senescence and inflammatory markers was evaluated by real-time q-PCR using the comparative ΔΔCt method. Also, protein expression of p16, Ki-67 and Caspase-3 were evaluated in fixed pellets or monolayer cultures and total number of cells was counted on consecutive sections using DAPI and Hematoxylin. Proteoglycan content was evaluated using SafraninO staining or DMMB assay to measure sulfated glycosaminoglycan (sGAG) and antibodies were used to stain for collagen type II expression. We observed 40% higher level of senescent cells in degenerate compare to the non-degenerate discs form unrelated individuals and a 10% increase when we compare degenerate compare to the non-degenerate discs of the same individual. Using the optimal effective and safe doses, curcumin and vanillin cleared 15% of the senescent cells in monolayer and up to 80% in pellet cultures. Also, they increased the number of proliferating and apoptotic cells in both monolayer and pellets cultures. The increase in apoptotic cell number and caspase-3/7 activity was specific to degenerate cells. Following treatment, mRNA expression levels of SASP factors were decreased by four to 32-fold compared to the untreated groups. Senescent cell clearance decreased, protein expression of MMP-3 and −13 by 15 and 50% and proinflammatory cytokines levels of IL-1, IL-6 and IL-8 by 42, 63 and 58 %. Overall matrix content was increased following treatment as validated by an increase in proteoglycan content in pellet cultures and surrounding culture media. This work identifies novel senolytic drugs for the treatment of IVD degeneration. Senolytic drugs could provide therapeutic interventions that ultimately, decrease pain and provide a better quality of life of patients living with IVDs degeneration and low back pain

Background. In 2009, NICE CG 88 guideline on the management of non-specific low back pain was published. We looked at whether the introduction of these guidelines has had an impact on the management of back pain within primary care. Methods. Patients with non-specific low back pain (> 6 weeks but < 12 months) attending spinal outpatient clinic in UHL between 2008 and 2011 were asked to complete questionnaires. Two groups were studied, the first prior to the publication of NICE guidelines, and the second afterwards. Patients with radicular, stenotic and red flag symptoms were excluded. Key audited treatment standards assessed included manual therapy, acupuncture, focused structured back exercise program, supervised group exercise program and lastly referral to a combined physical and psychological treatment program. Compliance with not using X-ray or MRI and treatment modalities such as injections, laser therapy, ultrasound therapy, lumbar supports, traction and TENS therapy was assessed. Secondary outcomes included VAS (back, leg pain), Oswestry Disability Index, MSP and MZD. Primary outcomes analyzed using 1-sided Fisher's exact test and secondary outcomes using two sample t tests. Results. 46 patients (pre-guidelines) and 34 patients (post-guidelines) were studied. Key findings showed significant deterioration in the institution of manual therapy in the post guidelines group (p value = 0.032) and an increase in use of MRI scan in post guidelines group (p value = 0.005). Deterioration in the mean presenting VAS for leg pain in post guidelines group noted. No significant difference between groups in the mean scores for VAS for back pain, ODI, MSP and MZDI. Conclusion. Our study suggests that the introduction of NICE guidelines on the management of low back pain has not yet influenced management in primary care. This may be due to lack of awareness of its implementation or due to adherence to local guidelines

The study used a qualitative methodology to explore the attitudes and beliefs of military physiotherapists and how these influenced the management of military patients presenting with chronic low back pain. Semi-structured interviews were undertaken with a sample of 16 military physiotherapists; the transcripts were analysed using a method of thematic content analysis. Analysis of semi-structured interviews undertaken resulted in the identification of six themes. These were: military culture, occupational issues, continuing professional development, clinical reasoning, need for cure and labelling the patient. The importance of understanding the occupational demands on their patients was considered highly significant by all of the military physiotherapists interviewed. However, there appeared generally poor knowledge of the biopsychosocial model in the management of low back pain and over-reliance on the medical model. Three-quarters of the military physiotherapists interviewed expressed frustration in their management of patients with low back pain. Similarly, the military physiotherapists displayed a poor awareness of current evidence-based clinical guidelines for the management of low back pain. The themes military culture and occupational issues were significant in influencing the military physiotherapist's clinical management. The highly physical and arduous nature of military occupations resulted in investigative procedures being requested at an earlier stage than is recommended in the current evidence-based guidelines. Justification for early investigations was provided on the basis of the unique occupational factors combined with requirement to optimise the number of military personnel able to deploy operationally. It was concluded that the management of low back pain in military personnel could be improved by increasing awareness of the current evidence-based guidelines. This would benefit both patients and the Armed Services, by reducing the disability caused by low back pain and increasing the number of operationally deployable service personnel

Low back pain is a common complaint and reason for patients to seek medical help. Studies have shown that 80% of people over 60 yrs of age will have suffered from it at one point in their lives. Low back pain, after the common cold, is the 2nd most common reason for patients to visit medical practitioners. Aim. The purpose of this survey was to establish a patient profile, risk factors, previous management and care strategies for patients presenting to the Orthopaedic Out Patient Department at an Academic Hospital with low back pain. Method. We reviewed 257 patients during a 6 month period from July 2010- December 2010.0. Patients were excluded if there were: XR deformities (eg. spondylolistheses, masses, cysts etc); associated neurology, incontinence or constitutional symptoms; previous vertebral column fracture or surgery or current malignancy. Patients referred for first visits were also excluded. Results. There were 206 females and 51 males. The average age of patients was 55 yrs. The average duration of symptoms was 6 months and the average duration of clinical follow-up at the institution was 8 months. The occupational setback due to this affliction was great: 23% were unemployed due to the pain and 21% receiving Disability Grants for it. The average BMI of these patients was 35. A smoking and alcohol history was not conspicuous and very few patients had a history of trauma. The investigative and treatment strategy and implementation in these patients was haphazard

Most people experience low back pain (LBP) at least once in their lifetime. A minority goes on to develop persistent LBP causing significant socioeconomic costs. Aim of this study was to identify factors that influence the progression of acute to persistent LBP at an early stage (Hilfiker et al. 2007). Prospective inception cohort study of patients attending a health practitioner for their first episode of acute LBP or recurrent LBP after a pain free period of at least six months. Patients were assessed at baseline addressing occupational and psychological factors as well as pain, disability, quality of life and physical activity, and followed up over six months. Baseline and follow-up questionnaires were based on the recommendations of the Multinational Musculoskeletal Inception Cohort Study (MMICS) Statement (Pincus et al. 2008). Variables were combined to the three indices ‘working condition’, ‘depression and maladaptive cognitions’ and ‘pain and quality of life’. The index ‘depression and maladaptive cognitions’ comprising of depression, somatisation, a resigned attitude towards the job, fear-avoidance, catastrophizing and negative expectations on return to work was found to be a significant baseline predictor for persistent LBP up to six months (OR 5.1; 95%CI 1.04–25.1). The diagnostic accuracy of the predictor model had a sensitivity of 0.54 and a specificity of 0.90. Positive likelihood ratio was moderate with 5.3, negative likelihood ratio 0.5. Overall predictive accuracy of the model was 81%. The area under the curve in receiver operating characteristic (ROC) analysis of the index was 0.78 (CI95% 0.65–0.92), demonstrating a satisfactory quality of discrimination. Psychological factors in patients with acute LBP in a primary care setting correlated with a progression to persistent LBP up to six months. The benefit of including factors such as ‘depression and maladaptive cognition’ in screening tools is that these factors can be addressed in primary and secondary prevention

Bertolotti first described articulation of the L5 transverse process with the sacrum as a cause of back pain in 1917. Since then little attention has been payed to these atypical articulations despite their high reported incidence. Here we describe our early experience of surgical treatment and propose a validated CT based classification of lumbosacral segment abnormalities (LSSA). 400 lumbosacral CT scans were reviewed (NBT), a classification devised and incidence of abnormalities recorded. 40 patients were selected and 4 independent observers classified each scan. Case notes for all patients (C&V) who received steroid injections into or surgical excision of LSSAs were reviewed. Results as follows:. 5 types of abnormality were identified. Type 0 - normal. Type 1 - asymmetrical shortening of the iliolumbar ligament. Type 2 - transverse process of L5 within 2mm of the sacrum. Type 3 - diarthrodial joint (3A: no evidence of degeneration 3B: degenerative change). Type 4 - transverse process and sacrum have fused. Type 5 - extends to L4. 54.5% of patients had abnormalities. The kappa values for the intra-observer results were 0.69 to 0.88 and the inter-observer ratings gave a combined score of over 0.7 indicating substantial agreement. Our CT classification of LSSAs is both straight forward to use and repeatable. The incidence of these abnormalities is higher in our population of CT scans compared to previous published series using plain radiographs. All patients treated with surgical excision of established articulations (Type 3A or above) reported good or excellent outcomes following excision

Background. There are no published studies investigating predictive values of psychological distress on effectiveness of epidural injection. Aims. To evaluate response to epidural injection (EI) in patients with chronic lower back pain (CLBP) with and without psychological distress. Methods. 96 patients with CLBP were recruited to this prospective cohort study. They had preoperative level of distress measured using Modified Zung Index (MZI) and Modified Somatic Perception Questionnaire (MSPQ); pain with Visual Analogue Score (VAS) and McGill Pain Questionnaire (MPQ); back related disability with Oswestry Disability Index (ODI). Fluoroscopic caudal EI comprising 80 mg methylprednisolone and 8 mg of lignocaine was performed. Scores were repeated at 6, 12, and 26 weeks. Successful outcome was Minimal Clinically Important Change (MCIC) in any given measure. Results. There were 62.5% not-distressed patients, 3.1% somatising, 15.6% depressed and 18.8% with mixed distress. Preoperative VAS was 82.4, MPQ 18.2 and ODI 51.6. Distress was associated with worse MPQ and ODI. Average VAS and MPQ improved significantly at 6 and 26 weeks. Mean change of ODI was significant but less than MCIC. Average magnitude of change of VAS and ODI did not differ between distressed and not-distressed. MPQ improved significantly more in the distressed. MZI was significant predictor of VAS-MCIC at 6 weeks while MZI and MSPQ at 6 months. None could predict this outcome independently. MSPQ was the only individual predictor of MPQ-MCIC at any time; MSPQ≥8 could predict MPQ-MCIC with 53%-sensitivity and 78%-specificity. MZI was significant predictor of ODI-MCIC but not individually.88% patients were satisfied with the treatment at 6 weeks and 63% at 6 months (significantly higher rate if somatising). Conclusions. Early psychological screen was correlated with outcome following epidural injection in CLBP and capable of predicting some response to treatment. Minimal, short-lived improvement of distress was not related to post-treatment CLBP measures

To investigate the effectiveness of surgical fusion for chronic low back pain (CLBP) compared to non-surgical intervention, databases were searched from 1966-2005. The meta-analysis was based on the mean difference in Oswestry Disability Index (ODI) change from baseline to follow-up. Four studies were eligible (634 patients). The pooled mean difference in ODI was 4.13 in favour of surgery (95% CI: -0.82-9.08; p=0.10; I2=44.4%). Surgery was associated with a 16% pooled rate of complication (95% CI: 12-20%, I2=0%). The cumulative evidence does not support surgical fusion for CLBP due to the marginal improvement in ODI which is of minimal clinical importance

Introduction. Numerous studies have been conducted to investigate the kinematics of the lumbar spine, and while many have documented its intricacies, few have analyzed the complex coupled out-of-plane rotations inherent in the low back. Some studies have suggested a possible relationship between patients having low back pain (LBP) or degenerative conditions in the lumbar region and various degrees of restricted, excessive, or poorly-controlled lumbar motion. Conversely, others in the orthopedic community maintain there has been no distinct correlation found between spinal mobility and clinical symptoms. The objective of this study was to evaluate both the in-plane and coupled out-of-plane rotational magnitudes about all three motion axes in both symptomatic and asymptomatic patients. Methods. Ten healthy, 10 LBP, and 10 degenerative patients were CT scanned and evaluated under fluoroscopic surveillance while performing flexion/extension of the lumbar spine. Three-dimensional, patient-specific bone models were created and registered to fluoroscopic images using a 3D-to-2D model fitting algorithm. In vivo kinematics were derived at specified increments and the overall in-plane flexion/extension and coupled out-of-plane rotations were analyzed using two techniques. The first method derived the maximal absolute rotational magnitude (MARM) at each level by subtracting the rotational motion in the increment exhibiting the most negative or least amount of rotation from the increment having the greatest amount of rotation. The second method was designed to isolate the path of rotation (POR) of the vertebrae at each level while performing the prescribed flexion/extension activity. By tracking the rotational path of the cephaled vertebrae as it articulated upon the more caudal vertebrae and summing the absolute rotation between each increment about each axis the POR was calculated over the entire flexion/extension activity. Results. Using both the MARM and POR methods, the average overall in-plane rotations between L1 and L5 were not significantly different among any of the groups, although the degenerative group did exhibit less in-plane range-of-motion compared to the healthy and LBP patients. At the L4–L5 level, patients in the healthy and LBP groups achieved 13.1° and 14.4° of rotation, respectively, compared to only 10.7° in the degenerative group. In addition, both of the symptomatic patient groups experienced less rotation during the extension phase of the activity. The coupled out-of-plane motions in both the LBP and degenerative subjects were significantly greater than those observed in healthy subjects (p=0.0199 and p<0.001, respectively). On average, LBP and degenerative patients achieved 5.5° and 7.1° more out-of plane rotational motion per level, respectively, compared to healthy subjects. Conclusions. These findings correlate with previous studies documenting paradoxical motions in the lumbar spine during an overall gross motion and support the idea of pain being a biological response to tissue injury which may result from excessive kinetic energy introduced into the biological system. Identification of these aberrant motion path magnitudes may aid in recognizing possible causes of pain in patients suffering from non-specific low back problems. Increased magnitudes of out-of-plane rotational paths observed in symptomatic patients may also be an indicator for progressive pathologies requiring surgical intervention in the lumbar spine region

Objectives. Sacroiliac joint dysfunction is a degenerative condition that can result in low back pain and is likely underdiagnosed. Diagnosis is made clinically with the patient experiencing pain in the sacroiliac joint region. Initial management is non-operative with pain management, physiotherapy, injections, and rhizolysis. If these fail then surgical management, by sacroiliac joint fusion, can be considered. The aim of this study was to review the outcomes of all patients who underwent sacroiliac joint fusion by a single surgeon in a large district general hospital between April 2018 and April 2023. Design and Methods. A retrospective review of all patients who underwent sacroiliac joint fusion between April 2018 and April 2023 was conducted. Data was collected from clinical letters, operative notes, and the British Spinal Registry. Oswestry Disability Index (ODI) and Visual Analogue Scale (VAS) for back and leg pain were recorded as well as any post-operative complications. Results. In total 19 patients underwent sacroiliac joint fusion. Mean age was 47 years (range 27 – 69 years). Nine were right sided procedures and ten were left. The mean BMI was 32.3. ODI improved from a mean of 55 pre-operative to 26 at one year and 15 at two years post-operative. VAS for back pain improved from a mean of six pre-operative to three at one year and one at two years post-operative. VAS for leg pain improved from a mean of five pre-operative to four at one year and zero at two years post-operative. There were no surgical site complications. One patient developed trochanteric bursitis post-operatively. Two patients have since undergone sacroiliac joint fusion on the contralateral side with a further patient awaiting contralateral surgery. Conclusion. In patients with sacroiliac joint pain where non-operative measures have failed to control symptoms sacroiliac joint fusion is a reliable and effective surgical option

7% of adolescent idiopathic scoliosis (AIS) patients also present with a pars defect. To date, there are no available data on the results of fusion ending proximal to a spondylolysis in the setting of AIS. The aim of this study was to analyze the outcomes of posterior spinal fusion (PSF) in this patient cohort, to investigate if maintaining the lytic segment unfused represents a safe option. Retrospective review of all patients who received PSF for AIS, presented with a spondylolysis or spondylolisthesis and had a min. 2-years follow-up. Demographic data, instrumented levels and preoperative radiographic data were collected. Mechanical complications, coronal or sagittal parameters, amount of slippage and pain levels were evaluated. Data from 22 patients were available (age 14.4 ± 2.5 years), 18 Lenke 1–2 and four Lenke 3–6. Five patients (24%) had an isthmic spondylolisthesis, all Meyerding I. The mean preoperative Cobb angle of the instrumented curves was 58 ± 13°. For 18 patients the lowest instrumented vertebra (LIV) was the last touched vertebra (LTV); for two LIV was distal to the LTV; for two, LIV was one level proximal to the LTV. The number of segments between the LIV and the lytic vertebra ranged from 1 to 6. At the last follow-up, no complications were observed. The residual curve below the instrumentation measured 8.5 ± 6.4°, the lordosis below the instrumented levels was 51.4 ± 13°. The magnitude of the isthmic spondylolisthesis remained constant for all included patients. Three patients reported minimal occasional low back pain. The LTV can be safely used as LIV when performing PSF for the management of AIS in patients with L5 spondylolysis

Low back pain is the single most common cause for disability in individuals aged 45 years or younger, it carries tremendous weight in socioeconomic considerations. Degenerative aging of the structural components of the spine can be associated with genetic aspects, lifetime of tissue exposure to mechanical stress & loads and environmental factors. Mechanical consequences of the disc degenerative include loss of disc height, segment instability and increase the load on facets joints. All these can lead to degenerative changes and osteophytes that can narrow the spinal canal. Surgery is indicated in patients with spinal stenosis who have intractable pain, altered quality of life, substantially diminished functional capacity, failed non-surgical treatment and are not candidates for non-surgical treatment. The aim was to determine the reasons for refusal of surgery in patients with established degenerative lumber spine pathology eligible for surgery. All patients meeting the study criteria, patients older than 18 years, patients with both clinical and radiological established symptomatic degenerative lumbar spine pathology and patients eligible for surgery but refusing it were recruited. Questionnaire used to investigate reasons why they are refusing surgery. Results 59 were recruited, fifty-one (86.4 %) females and eight (13.6 %) males. Twenty (33.8 %) were between the age of 51 and 60 years, followed by nineteen (32.2 %) between 61 and 70 years, and fourteen (23.7 %) between 71 and 80 years. 43 (72 %) patients had lumber spondylosis complicated by lumber spine stenosis, followed by nine (15.2 %) with lumbar spine spondylolisthesis and four (6.7 %) had adjacent level disease. 28 (47.4 %) were scared of surgery, fifteen (25.4 %) claimed that they are too old for surgery and nine (15.2 %) were not ready. Findings from this study outlined that patients lack information about the spinal surgery. Patients education about spine surgery is needed

Study design. Retrospective study. Objectives. To identify patient outcomes, in particular employment, >5-years following traumatic thoracolumbar fracture. Methods. 235 patients between the ages of 18–65 were identified from the hospital radiology database having sustained a traumatic thoracolumbar fracture on CT or MRI between 01/01/2013 and 31/01/2017. Questionnaires were sent out via post and available emails, with a reminder letter and phone calls. Retrospective data was gathered about employment status pre-fracture and >5-years post injury. Results. 26 patients had died at follow up leaving 209 patients. 108 (52%) were treated surgically and 101 (48%) conservatively. 106 replies were received with 85 (80%) opting in and 21 (20%) opting out. 68 (80%) patients completed the full questionnaire with 17 (20%) filling out a shortened questionnaire via a phone conversation. 52 (61%) patients underwent surgery and 33 (39%) were treated conservatively. The average follow up was 8 years. Prior to injury 66 (78%) were employed and 19 (22%) unemployed (of which 6 were full time students and 8 were retired). 49 (74%) of the previously employed patients returned to work at follow up with 35 (53%) working the same or increased hours. Regarding employment, there was no significant difference between surgically and conservatively treated patients (P=0.355) or the classification of the fracture (P=0.303). 16 (19%) patients reported back pain prior to their injury whilst 69 (81%) did not. There were 58 (68%) cases of new pain at follow up with the most affected area being the lumbar region in 43 (51%) patients. 32 (38%) patients reported neurological deficit post injury: 19 with subjective symptoms, 9 with objective symptoms and 4 suffered paralysis. Conclusion. >5-years following a traumatic thoracolumbar fracture most individuals return to employment. There was no significant difference between the severity of the fracture or how patients are treated on their employment outcomes

Psoas tendinopathy is a potential cause of groin pain after primary total hip arthroplasty (THA). The direct anterior approach (DAA) is becoming increasingly popular as the standard approach for primary THA due to being a muscle preserving technique. It is unclear what the prevalence is for the development of psoas-related pain after DAA THA, how this can influence patient reported outcome, and which risk factors can be identified. This retrospective case control study of prospectively recorded data evaluated 1784 patients who underwent 2087 primary DAA THA procedures between January 2017 and September 2019. Psoas tendinopathy was defined as (1) persistence of groin pain after DAA THA and was triggered by active hip flexion, (2) exclusion of other causes such as dislocation, infection, implant loosening or (occult) fractures, and (3) a positive response to an image-guided injection with xylocaine and steroid into the psoas tendon sheath. Complication-, re-operation rates, and patient-reported outcome measures (PROMs) were measured. Forty-three patients (45 hips; 2.2%) were diagnosed with psoas tendinopathy according to the above-described criteria. The mean age of patients who developed psoas tendinopathy was 50.8±11.7 years, which was significantly lower than the mean age of patients without psoas pain (62.4±12.7y; p<0.001). Patients with primary hip osteoarthritis were significantly less likely to develop psoas tendinopathy (14/1207; 1.2%) in comparison to patients with secondary hip osteoarthritis to dysplasia (18/501; 3.6%) (p<0.001) or FAI (12/305; 3.9%) (p<0.001). Patients with psoas tendinopathy had significantly lower PROM scores at 6 weeks and 1 year follow-up. Psoas tendinopathy was present in 2.2% after DAA THA. Younger age and secondary osteoarthritis due to dysplasia or FAI were risk factors for the development of psoas tendinopathy. Post-operatively, patients with psoas tendinopathy often also presented with low back pain and lateral trochanteric pain. Psoas tendinopathy had an important influence on the evolution of PROM scores

This study aims to 1) determine reported cannabis use among patients waiting for thoracolumbar surgery and to 2) identify demographics and health differences between cannabis-users and non-cannabis users. This observational cohort study is a retrospective national multicenter review data from the Canadian Spine Outcomes and Research Network registry. Patients were dichotomized as cannabis users and non-cannabis users. Variables of interest: age, sex, BMI, smoking status, education, work status, exercise, modified Oswestry Disability Index (mODI), the Numerical Rating Scales (NRS) for leg and back pain, tingling/numbness scale, SF-12 Quality of Life Questionnaire - Mental Health Component (MCS), use of prescription cannabis, recreational cannabis, and narcotic pain medication. Continuous variables were compared using an independent t-test and categorical variables were compared using chi-square analyses. Cannabis-use was reported by 28.4% of pre-operative patients (N=704), 47% of whom used prescription cannabis. Cannabis-use was reported most often by patients in Alberta (43.55%), British Colombia (38.09%) and New Brunswick (33.73%). Patients who reported using cannabis were significantly younger (mean=52.9 versus mean=61.21,). There was a higher percentage of concurrent narcotic-use (51.54 %) and smoking (21.5%) reported in cannabis-users in comparison to non-cannabis users (41.09%,p=0.001; 9.51%, p=0.001, respectively). There were significant differences in cannabis-use based on pathology (p=0.01). Patients who report using cannabis had significantly worse MCS scores (difference=3.93, p=0.001), and PHQ-8 scores (difference=2.51, p=0.001). There was a significant difference in work status (p=0.002) with cannabis-users reporting higher rates (20%) of being employed, but not working compared to non-cannabis users (11.13%). Non-cannabis users were more likely to be retired (45.92%) compared to cannabis-users (31.31%). There were no significant differences based on cannabis use for sex, education, exercise, NRS-back, NRS-Leg, tingling-leg, mODI, or health state. Thoracolumbar spine surgery patients are utilizing cannabis prior to surgery both through recreational use and prescription. Patients who are using cannabis pre-operatively did not differ in regards to reported pain or disability from non-users, though they did in demographic and mental health variables
