Purpose. Cognitive Muscular Therapy (CMT) is a new treatment for low back pain which integrates psychological techniques for pain management alongside training to improve postural control. Rather than focus on postural alignment or strength, CMT aims to improve the regulation of postural tone (low-level activity which supports the body against gravity). This is achieved by teaching patients an awareness of compensatory paraspinal activation, which can be triggered by overactivity of the abdominal muscles. The aim of this study was to understand whether CMT could reduce symptoms associated with low back pain and improve paraspinal muscle activation. Methods and results. Fifteen patients with chronic low back pain received seven weekly sessions of CMT from a physiotherapist. Clinical data was captured at baseline and two weeks after the intervention using the Roland-Morris questionnaire and the pain catastrophising scale. Activation of the erector spinae muscle during walking was also measured at baseline and after the final intervention session. Change data were analysed using paired t-tests. There was a 75% reduction (p<0.001) in the Roland-Morris score from a mean (SD) of 9.3(2.9) to 2.3(2.6), along with a 78% reduction in pain catastrophising (p<0.002) from 16.6(13) to 3.7(4.8). Activation of the contralateral erector spinae muscles reduced by 30% (p<0.01) during the contralateral swing phase of walking. Conclusion. In this small sample, CMT delivered large clinical improvements and reduced activation of the low back muscles during walking. Larger randomised trials are now required to confirm whether CMT could outperform existing physiotherapy treatments for chronic back pain. Conflict of interest. No conflicts of interest.

Objectives. Low back pain is strongly associated with degeneration of the intervertebral disc (IVD). During degeneration, altered matrix synthesis and increased matrix degradation, together with accompanied cell loss is seen particularly in the nucleus pulposus (NP). It has been proposed that notochordal (NC) cells, embryonic precursors for the cells within the NP, could be utilized for mediating IVD regeneration. However, injectable biomaterials are likely to be required to support their phenotype and viability within the degenerate IVD. Therefore, viability and phenotype of NC cells were analysed and compared within biomaterial carriers subjected to physiological oxygen conditions over a four-week period were investigated. Methodology. Porcine NC cells were incorporated into three injectable hydrogels: NPgel (a L-pNIPAM-co-DMAc hydrogel), NPgel with decellularized NC-matrix powder (dNCM) and Albugel (an albumin/ hyaluronan hydrogel). The NCs and biomaterials constructs were cultured for up to four weeks under 5% oxygen (n=3 biological repeats). Histological, immunohistochemical and glycosaminoglycans (GAG) analysis were performed to investigate NC viability, phenotype and extracellular matrix synthesis and deposition. Results. Histological analysis revealed that NCs survive in the biomaterials after four weeks and maintained cell clustering in NPgel, Albugel and dNCM/NPgel. NPgel and Albugel maintained NC cell markers and extracellular matrix. NC containing constructs excreted more GAGs over the four weeks than the acellular controls. Conclusion. NC cells maintain their phenotype and characteristic features in vitro when encapsulated into biomaterials. NC cells and biomaterial construct could potentially become a therapy to treat and regenerate the IVD. Conflicts of interest: No conflicts of interest.

Purposes of the study and background. Cognitive Functional Therapy (CFT) is a complex intervention that targets the biopsychosocial nature of low back pain (LBP). The barriers and facilitators to CFT have not previously been researched in the United Kingdom National Health Service (NHS). This study aimed to explore the barriers and facilitators of CFT in the NHS ahead of a future clinical trial. Methods and results. Participants who had completed a CFT intervention for persistent LBP and physiotherapists who had previously attended a CFT training workshop were recruited. Data were collected using one to one semi-structured interviews and were analysed thematically using framework method. Eight people with LBP and ten physiotherapists consented to participate. The key findings were that UK NHS physiotherapists can be trained to deliver CFT, they valued the training and felt confident to deliver CFT successfully to patients in NHS physiotherapy departments. Peer support and mentorship from a CFT practitioner was necessary for the physiotherapists to sustain changes to their clinical practice. Participants with LBP welcomed CFT as they felt it was beneficial and enabled them to self-manage their LBP and they could recognise the difference between CFT and usual care. The barriers, mainly related to the healthcare system, included short appointment times and poor availability of follow-up appointments. Conclusion. This is the first study to establish the barriers and facilitators to the implementation of CFT in the NHS. The findings of this study were used to inform the planning, design and delivery of a feasibility randomised controlled trial. Conflicts of interest: No conflicts of interest.

Purposes of the study and background. Cognitive Functional Therapy (CFT) is a psychologically informed, physiotherapist-led intervention that targets the biopsychosocial complexity of persistent low back pain (LBP). CFT has demonstrated positive outcomes in two randomised controlled trials (RCT) but has not previously been evaluated in the United Kingdom National Health Service (NHS). This study aimed to determine the feasibility of completing a definitive RCT, that will evaluate the clinical and cost-effectiveness of CFT in comparison to usual physiotherapy care (UPC) for people with persistent LBP in the NHS. Methods and results. A two-arm parallel feasibility RCT compared CFT with UPC in participants with persistent LBP. Data concerning study processes, resources, management and patient reported outcome measures (disability, pain intensity, quality of life and psychosocial function) were collected at baseline, three and six-month follow-up, analysed and evaluated in order to establish feasibility. Sixty participants (n=30 CFT and n=30 UPC) were recruited with 71.6% (n=43) retained at six-month follow-up. CFT was delivered to fidelity, relevant and clinically important outcome data were rigorously collected and CFT was tolerated by participants with no safety concerns. The Roland-Morris disability questionnaire was the most suitable primary outcome measure and sample size calculations were completed for a definitive RCT. Intention to treat analysis indicated a signal of effect in favour of CFT with moderate and large between group effect sizes observed across outcome measures at six-month follow-up. Conclusion. It is feasible to conduct a randomised study of CFT in comparison to UPC for NHS patients. A future fully powered clinical and cost effectiveness RCT could be completed. Conflicts of interest: No conflicts of interest. Sources of funding: Chartered Society of Physiotherapy, Physiotherapy Research Foundation


Background and study purpose. A recent systematic review with meta-analysis of eight randomised controlled trials concluded that Cognitive Functional Therapy (CFT) for low back pain might be effective in reducing disability, pain and fear-avoidance beliefs. However, the descriptions of a CFT intervention are not always clear. This study aimed to rate the replicability of the CFT interventions and control groups in the systematic review. Methods. Two reviewers independently extracted data from the study articles, protocols and appendices into Microsoft Excel using the Template for Intervention Description and Replication (TIDieR) checklist. This checklist has 12 items to describe the ‘why’, ‘what’, ‘who’, ‘how’, ‘where’, ‘when and how much’, ‘tailoring’, ‘modifications’, and ‘how well’ for each intervention. We rated the replicability of the CFT interventions and control groups as ‘reported’, ‘partially reported’ and ‘not reported’ and resolved discrepancies by consensus. Results. No studies reported 100% of the TIDieR items; the mean ‘reported’ rating was 54% (range 33–67%) for the CFT interventions and 35% (range 8–67%) for controls. The six most replicable items were the same for both CFT and control groups. These were ‘brief name’ (CFT=100%; control=100%), ‘why’ (CFT=100%; control=50%), ‘how’ (CFT=100%; control=50%), ‘what procedures’ (CFT=88%; control=63%), ‘where’ (CFT=88%; control=75%) and ‘planned adherence’ (CFT=75%; control=38%). Items that were not sufficiently ‘reported’ for either CFT or control groups included ‘when and how much’, ‘tailoring’ and ‘adherence’. Conclusion. Incomplete descriptions of CFT interventions mean that clinicians and patients cannot implement those that have demonstrated effectiveness, and poor descriptions of control groups prevent researchers from replicating them in future studies.

Purpose of the study and background. A 2011 Cochrane review concluded that spinal manipulative therapy (SMT) is no better than other interventions for reducing pain and improving function in chronic low back pain (CLBP). Using individual participant data (IPD) from trials has advantages, among others: a more precise estimate of the effect and the potential to identify moderators. Our objective was to assess the effect of SMT in adults with CLBP and to identify relevant moderators. Methods. All trials from the 2011 Cochrane review were included in this IPD. We updated the search (April 2016) IPD from eligible studies was requested. Primary outcomes were pain intensity (VAS/NRS) and back-specific function (RMDQ). Risk of bias was assessed. For the treatment effect, an one-stage approach (mixed model technique, intention-to-treat principle) was used; a second-stage approach was conducted as confirmation. For the moderator analyses, one-stage approach was conducted for 19 variables. Results. We obtained IPD from 21 RCTs (n= 4638). Most studies were pragmatic comparing the SMT effect to recommended therapies (e.g. exercise). Effects for SMT were slightly, but not clinically better compared to other therapies for primary outcomes. For the moderator analysis, 8 moderators showed a statistical significant effect at a specific time point (e.g. for SMT vs recommended therapy: age, both pain and function at 26 weeks). But for none of the moderators a consistent effect was identified across time points. Conclusion. Findings of the Cochrane review were confirmed. No clinically-relevant moderators were identified for SMT compared to other therapies for pain and function at any follow-up measure. No conflicts of interest.

This review provides a concise outline of the advances made in the care of patients and to the quality of life after a traumatic spinal cord injury (SCI) over the last century. Despite these improvements reversal of the neurological injury is not yet possible. Instead, current treatment is limited to providing symptomatic relief, avoiding secondary insults and preventing additional sequelae. However, with an ever-advancing technology and deeper understanding of the damaged spinal cord, this appears increasingly conceivable. A brief synopsis of the most prominent challenges facing both clinicians and research scientists in developing functional treatments for a progressively complex injury are presented. Moreover, the multiple mechanisms by which damage propagates many months after the original injury requires a multifaceted approach to ameliorate the human spinal cord. We discuss potential methods to protect the spinal cord from damage, and to manipulate the inherent inhibition of the spinal cord to regeneration and repair. Although acute and chronic SCI share common final pathways resulting in cell death and neurological deficits, the underlying putative mechanisms of chronic SCI and the treatments are not covered in this review.

Much debate exists over the value of exercise therapy for treating adolescent idiopathic scoliosis (AIS). This study aims to address the current evidence. An extensive search was carried out using the common medical databases, limiting results to clinical trials in English involving humans with defined outcome measures. 155 papers were identified and after applying strict inclusion criteria 12 papers remained for further analysis. These included 9 prospective cohort trials, 2 retrospective cohort trials and one case series. No randomised controlled trials were identified. Although all of the papers concluded an improvement in scoliotic curve after exercise therapy, not one of the papers had reliable methods or results to validate their conclusions. Identified shortcomings included, poor compliance with outpatient exercise regimes with no clear indication of who assessed for curve improvement, how it was assessed or what experience they had, nor was observer error for Cobb angle measurement taken into account. Additionally only a few of the studies had sound statistical analysis and no study could comment on whether the improvements seen were maintained after the exercise regime. Four previous systematic reviews have been performed finding favourable results for exercise therapy, but these were written by authors involved in the original research, adding significant reviewer bias. This systematic review has revealed only poor and low level evidence supporting the use of exercise therapy for treating AIS. Well designed controlled trials with randomisation are required to validate exercise therapy as an effective treatment option and as an appropriate use of NHS funds

This article reviews the current knowledge of the intervertebral disc (IVD) and its association with low back pain (LBP). The normal IVD is a largely avascular and aneural structure with a high water content, its nutrients mainly diffusing through the end plates. IVD degeneration occurs when its cells die or become dysfunctional, notably in an acidic environment. In the process of degeneration, the IVD becomes dehydrated and vascularised, and there is an ingrowth of nerves. Although not universally the case, the altered physiology of the IVD is believed to precede or be associated with many clinical symptoms or conditions including low back and/or lower limb pain, paraesthesia, spinal stenosis and disc herniation. New treatment options have been developed in recent years. These include biological therapies and novel surgical techniques (such as total disc replacement), although many of these are still in their experimental phase. Central to developing further methods of treatment is the need for effective ways in which to assess patients and measure their outcomes. However, significant difficulties remain and it is therefore an appropriate time to be further investigating the scientific basis of and treatment of LBP


Summary. Each patient received Cognitive Reassurance appropriate for and proportionate to his/her capacity through evidence informed explanation/education to enhance effective self-care and realistic self-management. Background and pathway. Changes to back and neck pain commissioning by our CCG required GPs not to refer to manual therapy until six weeks and upgrade GP care beyond that previous. 100 consecutive patients requesting GP appointment reporting back/neck pain were directed to a pragmatic service provided by an experienced manual therapy practitioner. Cognitive Reassurance reflecting evidenced informed biopsychosocial and salutogenic thinking was given at initial consultation/assessment. Patients were contacted at 10 and 20 days to ascertain their status. One sub-group suggested an opportunity for long-term follow-up. Pilot Objectives. Providing Cognitive Reassurance for achieving greater levels of patient engagement with self-management. Demonstrate full clinical triage by primary care providers is effective/practical.

Purpose of study and background. This systematic review sought to determine the efficacy of such targeted treatment in adults with non-specific low back pain (NSLBP). Many clinicians and researchers believe that tailoring treatment to subgroups of NSLBP positively impacts on patient outcomes. Method and results. MEDLINE, EMBASE, Current Contents, AMED, the Cochrane Central Register of Controlled Trials, reference list searching and citation tracking. Inclusion criteria were randomised controlled trials of targeted manual therapy and/or exercise for NSLPB that used trial designs capable of providing robust information on targeted treatment (treatment effect modification) for the outcomes of activity limitation and pain. Included trials needed to be hypothesis-testing studies published in English, Danish or Norwegian. Method quality was assessed using the Cochrane Back Review Group criteria. Four high-quality trials of targeted manual therapy and/or exercise for NSLBP met the inclusion criteria. One study showed statistically significant effects for short-term outcomes using McKenzie directional preference-based exercise. Other included studies showed effects that might be clinically important in size but were not statistically significant with their samples sizes, as research into subgroups requires much larger sample sizes than traditional two-group trials. Conclusions. The clinical implications of these results are that they provide very cautious evidence supporting the notion that treatment targeted to subgroups of patients with NSLBP may improve patient outcomes. The results were too patchy, inconsistent, and investigated in samples too small for clinical recommendations to be based on these findings. The research implications are that adequately powered controlled trials of treatment effect modification are uncommon

Purpose and Background. Traditional physiotherapy methods utilised in the management of NSCLBP have small effects on pain and disability and this is reflected by data previously collected by the host physiotherapy service. O'Sullivan has validated a novel classification system and matching treatment strategy known as Classification Based–Cognitive Functional Therapy (CB-CFT) for people with NSCLBP. Briefly, CB-CFT is a behavioural and functional management approach to NSCLBP. A recent RCT employing CB-CFT has demonstrated superior outcomes in comparison to traditional physiotherapy methods advocated by clinical practice guidelines. It was unknown if CB-CFT improved outcomes for people with NSCLBP attending an NHS physiotherapy service, therefore an evaluation of practice was proposed. Methods and Results. People referred to physiotherapy with NSCLBP were assessed and treated by a physiotherapist trained in the delivery of CB-CFT. Primary outcomes of interest included the Oswestry Disability Index (ODI) and Numerical Pain Rating Scale (NPRS). A retrospective evaluation was performed for sixty-one people referred to physiotherapy with NSCLBP. Statistically significant improvements in disability (ODI p<0.001) and pain (NPRS p<0.001) were demonstrated. 88% of people achieved minimum clinically important change, defined as >10 points for the ODI and 75% of people achieved minimum clinically important change, defined as >2 on NPRS. Mean improvement of 24.7 points for the ODI and 3.0 for NPRS was observed immediately following CB-CFT, demonstrating large effect sizes of 1.56 and 1.21 respectively. Conclusion. CB-CFT can be successfully implemented into a NHS Physiotherapy Service producing outcomes that are superior to those previously reported for NSCLBP

Background

CB-CFT targeting specific pain provoking posture/movements in NSCLBP patients was shown more beneficial than current best practice. Resources for such interventions are substantial and so modifications for today's NHS are warranted. This study investigated feasibility and effect of CB-CFT delivered in a group setting (CB-CFT/G).

Methods

Twenty three patients referred to Physiotherapy with NSCLBP undertook (i) 6 week CB-CFT/G(n=13) or (ii) current best practice (C)(n=10). Outcomes: Oswestry Disability Questionnaire (ODQ), pain (VAS), fear avoidance (Tampa Scale of Kinaesiophobia;TSK), physical activity (International Physical Activity Questionnaire;IPAQ), distress&risk assessment (DRAM), StarTBack and satisfaction. Unpaired t-tests assessed between-group difference in mean change of each outcome (p<0.05).

Aims. Patients with differentiated thyroid carcinomas (DTCs) have a favourable long-term survival. Spinal metastases (SMs) cause a decline in performance status (PS), directly affecting mortality and indirectly preventing the use of systemic therapies. Metastasectomy is indicated, if feasible, as it yields the best local tumour control. Our study aimed to examine the long-term clinical outcomes of metastasectomy for SMs of thyroid carcinomas. Methods. We collected data on 22 patients with DTC (16 follicular and six papillary carcinomas) and one patient with medullary carcinoma who underwent complete surgical resection of SMs at our institution between July 1992 and July 2017, with a minimum postoperative follow-up of five years. The cancer-specific survival (CSS) from the first spinal metastasectomy to death or the last follow-up was determined using Kaplan-Meier analysis. Potential factors associated with survival were evaluated using the log-rank test. We analyzed the clinical parameters and outcome data, including pre- and postoperative disability (Eastern Cooperative Oncology Group PS 3), lung and non-spinal bone metastases, and history of radioiodine and kinase inhibitor therapies. Results. Lung and other bone metastases at the time of surgery were observed in ten and eight patients, respectively. Three patients experienced local tumour recurrences at the operated site. The five- and ten-year CSS rates in the 22 patients with DTC were 77% and 52%, respectively. Pre- and postoperative disability and operative site tumour recurrence were identified as risk factors for short postoperative survival. Conclusion. Metastasectomy for resectable SM from DTC yielded favourable results and has the potential to improve survival. Cite this article: Bone Joint J 2023;105-B(5):575–582

Aims. To investigate the correlations among cytokines and regulatory T cells (T-regs) in ankylosing spondylitis (AS) patients, and their changes after anti-tumour necrosis factor-α (TNF-α) treatment. Methods. We included 72 AS patients with detailed medical records, disease activity score (Bath Ankylosing Spondylitis Disease Activity Index), functional index (Bath Ankylosing Spondylitis Functional Index), and laboratory data (interleukin (IL)-2, IL-4, IL-10, TNF-α, interferon (IFN)-γ, transforming growth factor (TGF)-β, ESR, and CRP). Their peripheral blood mononuclear cells (PBMCs) were marked with anti-CD4, anti-CD25, and anti-FoxP3 antibodies, and triple positive T cells were gated by flow cytometry as T-regs. Their correlations were calculated and the changes after anti-TNF-α therapy were compared. Results. The frequency of T-regs in PBMCs was positively correlated to ESR and CRP in AS (r = 0.35 and 0.43; p = 0.032 and 0.027, respectively), and there was also a significant correlation between serum level of TNF-α and CRP (p = 0.041). The frequency of T-regs in PBMCs positively correlated to serum levels of TNF-α, IL-10, and TGF-β, while IL-2, IL-4, and IFN-γ showed opposite results. After anti-TNF-α treatment, there were significantly lower serum levels of TNF-α, IL-10, TGF-β, and frequency of T-regs in PBMCs among these AS patients (p = 0.026, 0.032, 0.029, and 0.037, respectively). Conclusion. In AS patients, proinflammatory cytokine may give positive feedback to induce more T-reg production and anti-inflammatory cytokine secretion to suppress this inflammatory status, and they can be reversed by anti-TNF-α therapy. However, the detailed interactions among T-regs and complex cytokine networks in autoinflammatory diseases still need more studies and further functional assay.

Aims. People with severe, persistent low back pain (LBP) may be offered lumbar spine fusion surgery if they have had insufficient benefit from recommended non-surgical treatments. However, National Institute for Health and Care Excellence (NICE) 2016 guidelines recommended not offering spinal fusion surgery for adults with LBP, except as part of a randomized clinical trial. This survey aims to describe UK clinicians’ views about the suitability of patients for such a future trial, along with their views regarding equipoise for randomizing patients in a future clinical trial comparing lumbar spine fusion surgery to best conservative care (BCC; the FORENSIC-UK trial). Methods. An online cross-sectional survey was piloted by the multidisciplinary research team, then shared with clinical professional groups in the UK who are involved in the management of adults with severe, persistent LBP. The survey had seven sections that covered the demographic details of the clinician, five hypothetical case vignettes of patients with varying presentations, a series of questions regarding the preferred management, and whether or not each clinician would be willing to recruit the example patients into future clinical trials. Results. There were 72 respondents, with a response rate of 9.0%. They comprised 39 orthopaedic spine surgeons, 17 neurosurgeons, one pain specialist, and 15 allied health professionals. Most respondents (n = 61,84.7%) chose conservative care as their first-choice management option for all five case vignettes. Over 50% of respondents reported willingness to randomize three of the five cases to either surgery or BCC, indicating a willingness to participate in the future randomized trial. From the respondents, transforaminal interbody fusion was the preferred approach for spinal fusion (n = 19, 36.4%), and the preferred method of BCC was a combined programme of physical and psychological therapy (n = 35, 48.5%). Conclusion. This survey demonstrates that there is uncertainty about the role of lumbar spine fusion surgery and BCC for a range of example patients with severe, persistent LBP in the UK.

Aims. Implant-related postoperative spondylodiscitis (IPOS) is a severe complication in spine surgery and is associated with high morbidity and mortality. With growing knowledge in the field of periprosthetic joint infection (PJI), equivalent investigations towards the management of implant-related infections of the spine are indispensable. To our knowledge, this study provides the largest description of cases of IPOS to date. Methods. Patients treated for IPOS from January 2006 to December 2020 were included. Patient demographics, parameters upon admission and discharge, radiological imaging, and microbiological results were retrieved from medical records. CT and MRI were analyzed for epidural, paravertebral, and intervertebral abscess formation, vertebral destruction, and endplate involvement. Pathogens were identified by CT-guided or intraoperative biopsy, intraoperative tissue sampling, or implant sonication. Results. A total of 32 cases of IPOS with a mean patient age of 68.7 years (37.6 to 84.1) were included. Diabetes, age > 60 years, and history of infection were identified as risk factors. Patient presentation upon admission included a mean body temperature of 36.7°C (36.1 to 38.0), back pain at rest (mean visual analogue scale (VAS) mean 5/10) and when mobile (mean VAS 6/10), as well as elevated levels of CRP (mean 76.8 mg/l (0.4 to 202.9)) and white blood cell count (mean 9.2 units/nl (2.6 to 32.8)). Pathogens were identified by CT-guided or conventional biopsy, intraoperative tissue sampling, or sonication, and Gram-positive cocci presented as the most common among them. Antibiotic therapy was established in all cases with pathogen-specific treatment in 23 (71.9%) subjects. Overall 27 (84.4%) patients received treatment by debridement, decompression, and fusion of the affected segment. Conclusion. Cases of IPOS are rare and share similarities with spontaneous spondylodiscitis. While procedures such as CT-guided biopsy and sonication are valuable tools in the diagnosis of IPOS, MRI and intraoperative tissue sampling remain the gold standard. Research on known principles of PJI such as implant retention versus implant exchange need to be expanded to the field of spine surgery. Cite this article: Bone Jt Open 2023;4(11):832–838

Introduction. Treatment of spinal metastatic disease has evolved with the advent of advanced interventional, surgical and radiation techniques. Spinal Oligometastatic disease is a low volume disease state where en bloc resection of the tumour, based on oncological principles, can achieve maximum local control (MLC). Hybrid therapy incorporating Separation surgery (>2mm clearance of the thecal sac) and Stereotactic Ablative Radiotherapy (SABR) offer an alternative approach to achieving MLC. Hybrid therapy is also a viable option in patients eligible for SBRT who have failed conventional radiation therapy. En-bloc surgery may be a suitable option for those patients who are ineligible for or have failed SBRT. A multidisciplinary approach is particularly important in the decision-making process for these patients. Metal free instrumentation is aiding the optimization of these surgeries. The authors present a supra-regional centre's experience in managing spinal oligometastases. Methods. Retrospective review of oligometastatic spinal disease at a supra-regional centre between 2017 and 2021. Demographics, operative course, complications and Instrument type are examined. Results. Demographics: 24 patients with mean age 53.8y (range 12–77), 44% (40y–59y), 40% (60y–69y); 51% Male. Histology: Breast, Renal and Sarcoma accounted for 16.7% each; Thyroid, Prostate and Chordoma accounted for 8.3% each. Primary disease 7%, Synchronous 15%, Metachronous 78%. Instrumentation: Carbon-fibre (85%), TiAl (11%), Non-Instrumented (3%). Separation Surgery (70%), En-bloc resection/Tomita surgery (30%); SABR/Proton Beam Planned: 70%. Average length of hospital stays 19.1 days; twenty patients required intensive care admission for an average 2.7 days. 30 Day Mortality 8.3% (n=2: COVID-19 during admission and ventriculitis post discharge), 1y Mortality – 16.7%, 3y Mortality – 25%; Synchronous Mortality 75% (n=3) at 3 years. 30 Day infection rate 3%; 1y infection rate 7%. 1 Non-instrumented case developed proximal junctional failure post proton beam therapy and required a vascularised fibular strut graft. 2-year Revision for Local Recurrence 5% (Revision at 23 months). Conclusion. There are very few case series of oligometastatic spinal disease due to the relatively new concept of adjuvant SABR and its limited availability. Solid tumours pre-dominated the histology in our series with metachronous disease being the most commonly operated disease state. 92% of cases were eligible for SABR. The majority (85%) of cases were performed with Carbon-fibre instrumentation and has been shown to be safe with no mechanical failures in this series. Infection rates are in keeping with patients requiring radical radiotherapy with 3% early and 7% late. 30-day mortality was 8.3%, 1y=16.7% and 25% at last follow up. Mortality, as expected, is highest within the synchronous disease group and should be operated on sparingly. With the current management strategy, there was no local recurrence at 1 year and excellent local recurrence rate at 2 years (5%). Although radical en bloc surgery carries significant morbidity, it should be considered in selective cases to achieve MLC. All Oligometastatic cases deserve extra consideration and specialist MDT as not all are suitable for SABR. Multimodal Hybrid therapy, incorporating less invasive surgical techniques and SABR, represents a paradigm shift in achieving MLC in oligometastatic spinal disease

Aims. A variety of surgical methods and strategies have been demonstrated for Andersson lesion (AL) therapy. In 2011, we proposed and identified the feasibility of stabilizing the spine without curettaging the vertebral or discovertebral lesion to cure non-kyphotic AL. Additionally, due to the excellent reunion ability of ankylosing spondylitis, we further came up with minimally invasive spinal surgery (MIS) to avoid the need for both bone graft and lesion curettage in AL surgery. However, there is a paucity of research into the comparison between open spinal fusion (OSF) and early MIS in the treatment of AL. The purpose of this study was to investigate and compare the clinical outcomes and radiological evaluation of our early MIS approach and OSF for AL. Methods. A total of 39 patients diagnosed with AL who underwent surgery from January 2004 to December 2022 were retrospectively screened for eligibility. Patients with AL were divided into an MIS group and an OSF group. The primary outcomes were union of the lesion on radiograph and CT, as well as the visual analogue scale (VAS) and Oswestry Disability Index (ODI) scores immediately after surgery, and at the follow-up (mean 29 months (standard error (SE) 9)). The secondary outcomes were total blood loss during surgery, operating time, and improvement in the radiological parameters: global and local kyphosis, sagittal vertical axis, sagittal alignment, and chin-brow vertical angle immediately after surgery and at the follow-up. Results. Data for 30 patients with AL were evaluated: 14 in the MIS group and 16 in the OSF group. All patients were followed up after surgery; no nonunion complications or instrumentation failures were observed in either group. No significant differences in the VAS and ODI scores were identified between the two groups. Mean ODI improved from 51 (SE 5) to 17 (SE 5) in the MIS group and from 52 (SE 6) to 19 (SE 5) in the OSF group at the follow-up. There were significant improvements in total blood loss (p = 0.025) and operating time (p < 0.001) between the groups. There was also no significant difference in local kyphosis six months postoperatively (p = 0.119). Conclusion. Early MIS is an effective treatment for AL. MIS provides comparable clinical outcomes to those treated with OSF, with less total blood loss and shorter operating time. Our results support and identify the feasibility of solid immobilization achieved by posterior instrumentation without bone graft via MIS for the treatment of AL.
