Thoracic back pain caused by osteoarthritis of a single costovertebral joint is a poorly recognised condition. We report a series of five patients who were successfully treated by resection arthroplasty of this joint. Each had received a preliminary image-guided injection of local anaesthetic and steroid into the joint to confirm it as the source of pain. The surgical technique is described. There were no complications. The pain improved from a mean of 7.0 (6 to 8) on a visual analogue scale to 2.0 (0 to 4) post-operatively. The final post-operative Oswestry disability index was a mean of 19.4 (9 to 38). Isolated osteoarthritis of a costovertebral joint is a rare but treatable cause of thoracic back pain. It is possible to obtain excellent short- and intermediate-term relief from pain with resection arthroplasty in appropriately selected patients

Purpose and background:. Implementation fidelity (IF) is the extent to which an intervention is implemented as intended by its developers, and increases confidence that changes in study outcomes are due to the effect of the intervention itself and not due to variability in implementation. The aim of this study was to evaluate the IF within a behaviour-change self-management intervention for people with chronic low back pain and/or osteoarthritis, consisting of six weekly sessions (SOLAS ISRCTN49875385). Methods:. In a sample of data, the intervention was delivered by physiotherapists (n=9) in seven sites. IF was assessed using self-report (by physiotherapists) of all sessions (n=60), direct observations (by the research team) of 40% of the sessions (n=24) and audio-recorded observations (by the research team) of all sessions (n=60) using checklists. Data were analysed in SPSSv20 to assess % agreement between methods and fidelity scores. Results:. Agreement between direct observations and audio-recordings was 86.6%, with inter-rater reliability of 84.6% of the audio-recordings. Agreement between the direct observations and self-report was 74.6%. Four sites scored above 80% (‘high’ fidelity) with three scoring between 70 and 80% (‘moderate fidelity’). Four physiotherapists scored between 83–100% with five scoring from 72.5% to 78.8%. There was no significant difference in the fidelity scores across sessions with scores ranging from 74% to 88.8%. Conclusions:. Self-report data may be of limited use for assessing IF, though it may have benefits in terms of enhancing IF. Overall, fidelity levels ranged from moderate to high which will provide valuable information for the interpretation of the trial's clinical effectiveness

Background. Medical Research Council (MRC) guidelines recommend applying theory within interventions to explain how behaviour change occurs. Guidelines endorse self-management of chronic low back pain (CLBP) and osteoarthritis (OA), but evidence for its effectiveness is weak. This literature review aimed to determine the use of behaviour change theory and techniques within group-based self-management randomised controlled trials for chronic musculoskeletal pain, including CLBP and OA. Methods. A two phase search strategy of electronic databases was used to identify systematic reviews and studies relevant to this area. Articles were coded independently for their use of behaviour change theory, and the number of behaviour change techniques (BCTs) was identified using a 93 item taxonomy, Taxonomy (v1). Results. 25 articles of 22 studies met the inclusion criteria, of which only three reported having based their intervention on theory, and all used Social Cognitive Theory. A total of 29 BCTs were coded across all articles with the most commonly identified techniques being ‘instruction on how to perform the behaviour’, ‘demonstration of the behaviour’, ‘behavioural practice’, ‘credible source’, ‘graded tasks’ and ‘body changes’. Conclusion. The findings demonstrate that theoretically driven research within self- management for chronic musculoskeletal pain is lacking, or is poorly reported and may partly explain the weak evidence surrounding its effectiveness, Future research that follows MRC and CONSORT guidelines regarding the use of theory and the importance of its reporting is warranted. Programmes should be theoretically based, and focus on comprehensive reporting of all trial aspects, including the basis of technique and theory selection.

Background. Osteoarthritis (OA) and chronic low back pain (CLBP > 12 weeks duration) are two of the most common and costly chronic musculoskeletal conditions globally. Healthcare service demands mean that group-based multiple condition interventions are of increasing clinical interest and a priority for research, but no reviews have evaluated the effectiveness of group-based physiotherapy-led self-management interventions (GPSMI) for both conditions concurrently. Rapid review methodologies are an increasingly valid means of expediting knowledge dissemination and are particularly useful for addressing focused research questions. Methods. The electronic databases of MEDLINE, EMBASE, CINAHL, Cochrane Database of Systematic Reviews and Cochrane Register of Controlled Trials were searched from the earliest date possible to August 26. th. 2013. Structured group-based interventions that aimed to promote self-management and that were delivered by health-care professionals (including at least one physiotherapist) involving adults with OA and/or CLBP were eligible for inclusion. The screening and selection of studies, data extraction and risk of bias assessment were conducted independently by two reviewers. Results. 22 studies were found (10 OA, 12 CLBP). The most commonly assessed outcomes were pain, disability, quality of life and physical function. No significant difference was found between the effectiveness of GPSMI and individual physiotherapy or usual general practitioner care for any outcome. Conclusion. GPSMI is as clinically effective as individual physiotherapy, but the best methods of measuring clinical effectiveness warrant further investigation. Further research is also needed to determine the cost-effectiveness of GPSMI and its implications. Conflicts of interest: No conflicts of interest.

Background. Implementation fidelity is the extent to which an intervention is delivered as intended by intervention developers, and is extremely important in increasing confidence that changes in study outcomes are due to the effect of the intervention itself and not due to variability in implementation. Growing demands on healthcare services mean that multiple condition interventions involving highly prevalent musculoskeletal pain conditions such as chronic low back pain (CLBP) and/or osteoarthritis (OA) are of increasing clinical interest. This is the first in-depth review of implementation fidelity within self-management interventions for any musculoskeletal pain condition. Methods. Structured self-management interventions delivered by health-care professionals (including at least one physiotherapist) in a group format involving adults with OA of the lumbar spine, hip or knee and/or CLBP were eligible for inclusion. The National Institutes of Health Behaviour Change Consortium Treatment Fidelity checklist was used by two independent reviewers to assess fidelity. Results. In total, 22 studies were found. Fidelity was found to be very low within the included studies with only one study achieving >80% on the framework. The domain of Training of Providers achieved the lowest fidelity rating (10%) across all studies. Conclusion. Overall levels of fidelity are poor in self-management interventions for CLBP and/or OA; however it is unclear whether fidelity is poor within the trials included in this review, or just poorly reported. There is a need for the development of fidelity reporting guidelines and for the refinement of fidelity frameworks upon which to base these guidelines.

Purpose/Background. More than 20 million UK citizens have MSK conditions, and post-pandemic the backlog awaiting access to MSK services has increased. The most prevalent MSK condition is low back pain (LBP), and getUBetter has been recommended by NICE as one of five digital health technologies for helping manage LBP. Purpose: Evaluate impact of getUBetter on a community MSK waiting list. Methods/Results. Mixed methods approach used. All patients on community MSK waiting list sent a postal invite for getUBetter. Number of downloads and frequency of use recorded, and users emailed questionnaire exploring outcomes and satisfaction. Rate users removed themselves from the waiting list compared with non-users. Of 14,500 invitations, 657(4.5%) patients downloaded getUBetter, 395(60.1%) used it once and 138(21%) ≥3 times. Seventeen (7%) of 239 patients canvassed responded to questionnaire, 17% reported improved pain, 21% reported improved confidence and had been helped back to work. Twenty-five percent better understood their condition and 43% needed no other treatment. Seventy-five percent were critical of limited content, with chronic osteoarthritis mentioned. 69.6% of users removed themselves from the waiting list. This was 29.6% above the rate for non-users. Conclusion. Sending postal invites for getUBetter to a MSK waiting list yielded limited uptake. However, despite some criticisms, patients using it reported improved pain, early return to usual activities, and improved confidence in self-management. Some patients recovered without the need for additional support and getUBetter shows some potential for reducing a MSK waiting list. Clearly further work is required to explore methods to increase patient uptake and maximise impact. Conflicts of interest. None. Sources of funding. None

Background. Lateral lumbar spine statistical shape models (SSM) have been used previously to describe associations with osteoarthritis and back pain. However, associations with factors such as osteoporosis, menopause and parity have not been explored. Methods and Results. A 143-point SSM, describing L1 to the top of L5, was applied to lateral spine iDXA scans from UK Biobank. Associations with self-reported osteoporosis, menopause, parity and back pain and the first 10 modes of variation were examined using adjusted binary logistic regression or linear regression (adjusted for age, height, weight and total spine BMD). We report odds ratios with 95% confidence intervals for each standard deviation change in mode. Complete data were available for 2494 women. Mean age was 61.5 (± 7.4) years. 1369 women reported going through menopause, 96 women self-reported osteoporosis and 339 women reported chronic back pain. 80% of women reported at least 1 live birth. Lumbar spine shape was not associated with back pain in this cohort. Two modes were associated with menopause (modes 1 & 2), 1 mode with parity (mode 1) and 2 modes with osteoporosis (modes 3 & 5). Mode 1 (43.6% total variation), describing lumbar curvature was positively associated with both menopause [OR 1.15 95% CI 1.00–1.33, p=0.05] and parity [OR 1.058 95% CI 1.03–1.0, p=0.01]. Mode 3, describing decreased vertebral height was positively associated with osteoporosis [OR 1.40 95% CI 1.14–1.73, p=0.001]. Conclusion. Menopause and parity were associated with a curvier lumbar spine and osteoporosis with decreased vertebral height. Shape was not associated with back pain. No conflicts of interest.  .

Aims

Degenerative cervical spondylosis (DCS) is a common musculoskeletal disease that encompasses a wide range of progressive degenerative changes and affects all components of the cervical spine. DCS imposes very large social and economic burdens. However, its genetic basis remains elusive.

Purpose of study and background. We have previously reported the development of injectable hydrogels for potential disc regeneration (NPgel) or bone formation which could be utilized in spinal fusion (Bgel). As there are multiple sources of mesenchymal stem cells (MSCs), this study investigated the incorporation of patient matched hMSCs derived from adipose tissue (AD) and bone marrow (BM) to determine their ability to differentiate within both hydrogel systems under different culture conditions. Methods and Results. Human fat pad and bone marrow derived MSCs were isolated from femoral heads of patients undergoing hip replacement surgery for osteoarthritis with informed consent. MSCs were encapsulated into either NPgel or Bgel and cultured for up to 6 weeks in 5% (NPgel) or 21% (Bgel) O. 2. Histology and immunohistochemistry was utilized to determine phenotype. Both fat and bone marrow derived MSCs, were able to differentiate into both cell lineages. NPgel culture conditions increased expression of matrix components such as collagen II and aggrecan and NP phenotypic markers FOXF1 and PAX1, whereas Bgel induced expression of collagen I and osteopontin, indicative of osteogenic differentiation. Conclusion. NPgel and Bgel were able to differentiate patient derived MSCs from different sources into both NP and osteogenic lineages, which may give rise to novel treatment strategies for IVD degeneration and spinal fusion, enabling choice for cell source according to patients' circumstances and needs.

Aims

CRP is an acute-phase protein that is used as a biomarker to follow severity and progression in infectious and inflammatory diseases. Its pathophysiological mechanisms of action are still poorly defined. CRP in its pentameric form exhibits weak anti-inflammatory activity. The monomeric isoform (mCRP) exerts potent proinflammatory properties in chondrocytes, endothelial cells, and leucocytes. No data exist regarding mCRP effects in human intervertebral disc (IVD) cells. This work aimed to verify the pathophysiological relevance of mCRP in the aetiology and/or progression of IVD degeneration.

Aims

In this investigation, we administered oxidative stress to nucleus pulposus cells (NPCs), recognized DNA-damage-inducible transcript 4 (DDIT4) as a component in intervertebral disc degeneration (IVDD), and devised a hydrogel capable of conveying small interfering RNA (siRNA) to IVDD.

Background and purpose of the study. Axial Spondyloarthritis (axSpA) is commonly mistaken as chronic mechanical back pain. Delayed diagnosis averages 5- 8 years with impacts on effective and timely management, outcomes and quality of life. NICE Guidance (2017) highlights the importance of the recognition and referral of suspected axial spondyloarthritis. This study investigated the occurrence of physiotherapy care prior to diagnosis of axSpA within physiotherapy outpatient settings. Methods and results. A retrospective review was performed of all patients diagnosed with axSpA who had received physiotherapy care prior to their diagnosis from 1990–2016. Three or more episodes of care prior to diagnosis was taken as unrecognised axSpA. Information was obtained on diagnostic codes, number of episodes of care and contacts per episode from nine outpatient physiotherapy services. Analysis showed that 263 people (17–69 years) diagnosed with axSpAs had received physiotherapy care prior to diagnosis. Within this population, 103 (44%) had received ≥3 episodes of care. Number of contacts within each episode ranged from 3 (47 people) to 58 (1 person) [median=11 contacts-10 people]. Average time from initial physiotherapy episode to date of diagnosis was 6.4 years (range=0.3–12.8 years, median=8.8 years). The most common assigned diagnostic code was back pain (49.6%), followed by shoulder (11.1%), knee (8.5%), neck (7.7%), ankle/foot (4.3%), tendonitis (4.2%), joint pain (3.4%), osteoarthritis (3.4%) and sacroiliac joint (2%). Conclusion. Findings illustrate the extent of unrecognised axial spondyloarthritis referred to and missed in musculoskeletal physiotherapy practice. It is essential to improve screening and recognition of inflammatory back pain and possible axSpA in musculoskeletal assessments, supported by rheumatology referral guidance.

Background. The majority of adults will experience an episode of low back pain during their life. Patients with non-specific low back pain and lumbar disc degeneration (LDD) may experience spinal pain and morning stiffness because of a comparable inflammatory process as in patients with osteoarthritis of the knee and/or hip. Therefore, this study assessed the association between spinal morning stiffness, LDD and systemic inflammation in middle aged and elderly patients with low back pain. Methods. This cross-sectional study used the baseline data of the BACE study, including patients aged ≥55 years visiting a general practitioner with a new episode of back pain. The association between spinal morning stiffness, the radiographic features of lumbar disc degeneration and systemic inflammation measured with serum C-reactive protein was assessed with multivariable logistic regression models. Results. At baseline, a total of 661 back pain patients were included. Mean age was 66 years (SD 8), 416 (63%) reported spinal morning stiffness and 108 (16%) showed signs of systemic inflammation measured with CRP. Both LDD definitions were significantly associated with spinal morning stiffness (osteophytes OR=1.5 95% CI 1.1–2.1, narrowing OR=1.7 95% CI 1.2–2.4) and spinal morning stiffness >30 minutes (osteophytes OR=1.9 95% CI 1.2–3.0, narrowing OR=3.0 95% CI 1.7–5.2) For severity of disc space narrowing we found a clear dose response relationship with spinal morning stiffness. We found no associations between spinal morning stiffness and the features of LDD with systemic inflammation. Conclusions. This study demonstrated an association between the presence and duration of spinal morning stiffness and radiographic LDD features. No conflicts of interest. No funding obtained

Aims

Although lumbosacral transitional vertebrae (LSTV) are well-documented, few large-scale studies have investigated thoracolumbar transitional vertebrae (TLTV) and spinal numerical variants. This study sought to establish the prevalence of numerical variants and to evaluate their relationship with clinical problems.

Purpose and Background. Leg length discrepancy (LLD) occurs commonly and has been associated with osteoarthritis of the knee and the hip joints. However, the possible association between LLD and degenerative changes in the lumbar spine has not been investigated. Here we correlate the degree of LLD with degenerative changes in the hip joints and the lumbar spine. Methods and Results. A modification of Friberg's method was used to measure LLD and a novel method was devised to exclude magnification errors in standing radiographs of the lumbopelvic region. 5mm of LLD was considered significant. 75 sets (36 female and 39 male) of radiographs from adult patients presenting to chiropractic teaching clinics were used. Degenerative changes at hip and L4/5 and L5/S1 disc spaces were graded on a 4-point scale. Hip degeneration in men with significant LLD was [mean, 95% confidence interval] [1.35, 1.05–1.66], as opposed to men with no significant LLD [0.31, 0.1–0.53]. Degenerative changes at the L5/S1 spinal level in the group with significant LLD demonstrated values of [1.04, 0.75–1.33], compared to the group without significant LLD with values of [0.41, 0.22–0.61]. The association between LLD and lumbar degeneration was particularly strong in men and also in women at or above the age of 25. Conclusion. Here we demonstrate that LLD of 5mm or above, as measured by our method, is associated with significant degenerative changes in the hip joint in men and the L5/S1 motion segment in both men and women, but may be more significant in older women.

Aims/background. Current treatment recommendations advocate various exercise modalities for people with chronic Low Back Pain (cLBP). 1. Walking appears to represent an inexpensive and readily accessible activity for a range of individuals, including those who were previously sedentary. However, the effectiveness of such interventions are uncertain in cLBP. Methods. A systematic review was undertaken to examine the effectiveness of walking interventions across a range of chronic musculoskeletal pain conditions, including LBP. Six electronic databases were searched for relevant studies. Data for pain and self reported function were extracted and where appropriate, results were pooled and analysed using RevMan (v.5). Results. Twenty studies with a total of 1852 participants (Mean: 96) were included in the review. Only two provided data for cLBP, Data from one of these was not analysed as only median values were reported. The remaining study found no effect in favour of the walking intervention for pain (mean difference = −0.50 [95% confidence interval = −16.23, 17.23]) with a moderate improvement in function (−22.56 [−40.84, −4.26]). For osteoarthritis, analysis revealed small to moderate differences for both pain (−6.23 [−11.22, −1.24]; n=7) and function (−10.90 [−20.61, −1.19]; n=5). Discussion. Despite the potential benefits associated with walking, results of this systematic review found limited evidence to support the use of such interventions for people with cLBP. Further studies where walking is the predominant component of an overall intervention and which closely monitor any associated adverse events are required

Aims

Inflammatory response plays a pivotal role in the pathophysiological process of intervertebral disc degeneration (IDD). A20 (also known as tumour necrosis factor alpha-induced protein 3 (TNFAIP3)) is a ubiquitin-editing enzyme that restricts nuclear factor-kappa B (NF-κB) signalling. A20 prevents the occurrence of multiple inflammatory diseases. However, the role of A20 in the initiation of IDD has not been elucidated. The aim of the study was to investigate the effect of A20 in senescence of TNF alpha (TNF-α)-induced nucleus pulposus cells (NPCs).

Aims

The aim of this study was to investigate the clinical and radiographic outcomes of microendoscopic laminotomy in patients with lumbar stenosis and concurrent degenerative spondylolisthesis (DS), and to determine the effect of this procedure on spinal stability.

Aims

The aim of this study was to determine if positive Waddell signs were related to patients’ demographics or to perception of their quality of life.

Objectives

The objective of this study was to assess the association between whole body sagittal balance and risk of falls in elderly patients who have sought treatment for back pain. Balanced spinal sagittal alignment is known to be important for the prevention of falls. However, spinal sagittal imbalance can be markedly compensated by the lower extremities, and whole body sagittal balance including the lower extremities should be assessed to evaluate actual imbalances related to falls.
