Degenerative cervical myelopathy resulting in cord compromise is a progressive condition that results in significant quality of life limitations. Surgical treatment options available are anterior and/or posterior decompression of the affected levels. Patients are counselled pre-operatively that the aim of surgical intervention is to help prevent deterioration of neurology. Anecdotal evidence suggested improvements in both EMS and PROMs in this cohort of patients. A 2-year prospective study tested this hypothesis. 67 patients undergoing anterior cervical surgery were followed up to two years. Myelopathic features, radiological cord compression, myelomalacia change and levels of surgery were recorded. Pre/post intervention myelopathy scores/grades, and PROM's were recorded. Paired t-test was performed when comparing pre/post intervention scores and Annova test when comparing results across levels. Our prospective study identified statistically significant improvements in European myelopathy scores and grade and patient reported clinical outcomes in the said population.Purpose of Study and Background
Methodology and Results
Degenerative cervical myelopathy (DCM) is associated with progressive neurological deterioration. Surgical decompression can halt but not reverse this progression. The Modified Japanese Orthopaedic Assessment (MJOA) tool is recommended by international guidelines to grade disease severity into mild, moderate and severe, where moderate and severe are both recommended to undergo surgical intervention. During Covid-19 Nottingham University Hospitals (NUH) NHS Trust, identified DCM patients as high risk for sustaining permanent neurological damage due to surgical delay. The Advanced Spinal Practitioner (ASP) team implemented a surveillance project to evaluate those at risk. A spreadsheet was compiled of all DCM patients known to the service. Patients were telephoned (Oct-Nov 2021) by an ASP. MJOA score was recorded and those describing progressive deterioration were reviewed by the ASP team on a spinal same day emergency assessment unit. Incident forms were completed for clinical deterioration and recorded as severe harm. Acute, progressive neurological deterioration was fast tracked for emergency surgical decompression.Introduction

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. 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.Purposes of the study and background

Scoliosis is described as a lateral spinal curvature exceeding ten degrees on radiograph with vertebral rotation. Approximately 80% of scoliosis presentations are adolescent idiopathic scoliosis (AIS). Current management for AIS in the UK occurs in Surgeon or Paediatrician-led clinics and can be conservative or surgical. The musculoskeletal assessment and triage of AIS appears well-suited to an advanced physiotherapist practitioner (APP) skill set. The aim of this service evaluation was to scope, develop, implement and evaluate a four-month pilot of an APP-led AIS triage pathway. Spinal Consultant deformity and scoliosis clinics were scoped and observed. Clinic inclusion criteria and a patient assessment form was developed. An APP AIS clinic was set up beside a consultant led clinic. All patients assessed were discussed with a spinal surgeon. Consultant and APP agreement (% of total), waiting times, surgical conversion, and patient satisfaction were reviewed. A clinical competency package was developed for training and development of APPs. A total of 49 patients were seen (20 sessions). Waiting list reduced from 10 weeks to 6 weeks. 45%(n=22) of new patients seen were diagnosed with AIS, 27% (n=6) were directly listed for surgery. Consultant/ APP percentage agreement was high for Cobb angle measurement (82%), management plans (90%), and further diagnostic requests (94%). There were no adverse events and high patient satisfaction levels (n=20), (100% Very satisfied or satisfied) were reported.Background

Serious traumatic injury is a leading cause of death and disability globally, with the majority of survivors developing chronic pain. The aims of this study were to describe early predictors of poor long-term outcome for post-trauma pain. We conducted a prospective observational study, recruiting patients admitted to a Major Trauma Centre hospital in England within 14 days of their injuries, and followed them for 12 months. We defined a poor outcome as Chronic Pain Grade ≥ II and measured this at both 6-months and 12-months. A broad range of candidate predictors were used, including surrogates for pain mechanisms, quantitative sensory testing, and psychosocial factors. Univariate models were used to identify the strongest predictors of poor outcome, which were entered into multivariate models.Background

To evaluate the clinical and cost-effectiveness of a physical and psychological group intervention (BOOST programme) compared to physiotherapy assessment and advice (best practice advice [BPA]) for older adults with neurogenic claudication (NC) which is a debilitating spinal condition. A randomised controlled trial of 438 participants. The primary outcome was the Oswestry Disability Index (ODI) at 12 months. Data was also collected at 6 months. Other outcomes included Swiss Spinal Stenosis Questionnaire (symptoms), ODI walking item, 6-minute walk test (6MWT) and falls. The analysis was intention-to-treat. We collected the EQ5D and health and social care use to estimate cost-effectiveness. Participants were, on average, 74.9 years old (SD 6.0). There was no significant difference in ODI scores between groups at 12 months (adjusted mean difference (MD): −1.4 [95% Confidence Intervals (CI) −4.03,1.17]), but, at 6 months, ODI scores favoured the BOOST programme (adjusted MD: −3.7 [95% CI −6.27, −1.06]). Symptoms followed a similar pattern. The BOOST programme resulted in greater improvements in walking capacity (6MWT MD 21.7m [95% CI 5.96, 37.38]) and ODI walking item (MD −0.2 [95% CI −0.45, −0.01]) and reduced falls risk (odds ratio 0.6 [95% CI 0.40, 0.98]) compared to BPA at 12 months. Probability that the BOOST programme is cost-effective ranged from 67%–89% across cost-effectiveness thresholds.Purpose and background

Intervertebral disc degeneration (DD) is a complex age-related condition that constitutes the main risk factor for disabling back pain. DD is assessed using different traits extracted from MR imaging (MRI), normally combined to give summary measures (e.g. Pfirmann score). The aetiology of DD is poorly understood and despite its high heritability (75%), the precise genetic predisposition is yet to be defined. Genome wide association study (GWAS) is used to discover genetic variants associated with a disease or phenotype. It tests variants across the whole genome. It requires large samples to provide adequate but unfortunately there is poor availability of spine imaging data due to the high cost of MRI. We have adopted new methods to examine different MRI traits independently and use the information of those traits to boost GWAS power using specialized statistical software for jointly analyse correlated traits. We examined DD MRI features disc narrowing, disc bulge, disc signal intensity and osteophyte formation in the TwinsUK cohort who had undergone T2-weighted sagittal spine MRI. GWAS were performed on the four traits. MTAG software was used to boost single trait GWAS power using the information in the other trait GWAS. 9 different loci were identified.Background
Methods/Results
Low mood and distress are commonly reported with by people with persistent musculoskeletal pain and may be mislabelled as ‘depression’. In order to understand how pain-related distress is conceptualised and managed in primary care consultations, we explored understanding of pain-related distress and depression from the perspectives of people with persistent musculoskeletal pain and general practitioners (GPs). Semi-structured interviews with 21 GPs and 21 people with persistent musculoskeletal pain were conducted. The majority of people with pain had back pain (15/21). Data were analysed thematically using constant comparison techniques. Participants described challenges distinguishing between distress and depression in the context of persistent pain but described strategies to make this distinction. Some people with pain described how acceptance of their situation was key, involving optimism about the future and creation of a new identity. Some GPs expressed ‘therapeutic nihilism’, with uncertainty about the cause of pain and thus how to manage people with both pain and distress, whilst GPs who could identify and build on optimism with patients described how this could help the patient to move forwards.Background and study purpose

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. 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.Purposes of the study and background

Free From Pain (aka Fear Reduction, Exercise Early with Food from plants, Rest and relaxation, Organisation and Motivation to decrease Pain from Arthritis and Increase Natural Strength) is a functional rehabilitation programme to combat sarcopenia and musculoskeletal pain in seniors. It is also published as a book (ISBN-0995676941). The aim of this audit was to evaluate the safety and suitability of the exercises and the usefulness of the exercise book. Participants were volunteers who paid to attend the Free From Pain Exercise programme. Participants evaluated the exercises using a 5-point Likert scale and the Exercise Book using the Usefulness Scale for Patient Information Material (USE). 30 participants attended the Free From Pain programme. 26 participants completed the questionnaire. This included 20 females and 6 males, with a mean age of 76 years. The mean scores on the 0 to 5 Likert scales were A) Exercises were suitable? 4.69; B) Exercises were safe? 4.58; C) Absence of any injury or medical event whilst exercising? 4.58; D) Covered all body parts? 4.38; E) Easy to do at home? 4.42; F) Encouraged to do more exercise? 4.42; G) Recommend to family and friends? 4.50. The mean scores of the cognitive, emotional, and behavioural sub domains of the USE scale, scored 0 to 30, were 25.23, 23.73 and 23.69, respectively.Background

The purpose of this project was to evaluate whether OHEIs could facilitate student physiotherapy placement training in their educational outpatient clinics. The National Health Service (NHS) is actively promoting Allied Health Professionals (AHPs) to have a greater role in supporting healthcare delivery. There are challenges to increasing AHP numbers and one of these is providing enough student training placements to meet demand.Purpose of the study
Background
We have previously reported an injectable hydrogel (NPgel), which could deliver patients own stem cells, via small bore needles, decreasing damage to the annulus fibrosus. NPgel drives differentiation to NP cells and can inhibit the degenerate niche. However, clinical success of NPgel is dependent on the capacity to inject NPgel into naturally degenerate human discs, restore mechanical function to the IVD, prevent extrusion during loading and induce regeneration. This study assessed injectability of NPgel into human IVD, influence on mechanical properties, regeneration ability in an Cadaveric human discs were used to calculate disc height and to determine Youngs Modulus during simulated walking pre and post injection of NPgel, extrusion testing performed. Whole human IVDs were injected with NPgel +/− human BMPCs and maintained in culture under physiological loading regime for 4 weeks. Pre and post culture MRI imaging and in line biomechanical characteristics determined. Histology and immunochemistry performed for anabolic and catabolic factors.Background
Methodology
Cauda equina syndrome (CES) is a spinal condition requiring emergency spinal surgery once diagnosed. The patient-reported symptoms are often subtle and none have been shown to be sensitive or specific in confirming CES. Magnetic resonance image (MRI) is the diagnostic gold standard, and guidelines recommend MRI access within 24-hours of symptom presentation. Limited sequence MRI scans (sagittal T2 sequences of the whole spine) have been shown to successfully identify patients with scan-positive CES despite reducing the duration of an MRI. The aim of this audit was to examine utilisation of same-day MRI requests by spinal practitioners from a newly operational same-day emergency care spinal unit over the two-year period. Data was routinely collected over the two-year period and retrospectively reviewed. Data extraction occurred for cases of suspected CES with a same-day scan. Data extraction included type of MRI scan (lumbar/ whole spine/ CES protocol); outcome (admission/ discharge); final diagnosis. After clinical examination, only 258 (24% of 1085) suspected CES cases were identified and scanned within 24 hours, 58% (n=149) of which were with CES limited sequence scans. Only 12% (n=30) demonstrated scan- positive CES resulting in surgery within 24-hours. MRI same-day requests increased between 2020 (n=81, 21%) and 2021 (n=177, 26%), although utilisation of limited sequence scans improved (n=39, 48% in 2020; n=109, 62% in 2021).Background

Nucleus replacement surgery has the potential to be an early treatment option for chronic lower back pain. The surgery involves removal (nuclectomy) and replacement of the native degenerated nucleus with a material designed to restore the disc's physiological properties. Multiple techniques have been considered to perform a nuclectomy, however the advantages and disadvantages of each are not well understood. The aim of this study was to quantitatively compare three nuclectomy techniques: automated-shaver, rongeurs, and laser. Fifteen human vertebra-disc-vertebra lumbar specimens were split into three groups. Before and after nuclectomy axial mechanical tests were performed and T2-weighted 9.4T MRIs were acquired for each specimen. Using the automated-shaver and rongeur similar volumes of disc material were removed (2.51±1.10% and 2.76±1.39% of the total disc volume, respectively), whilst considerably less material was removed when using the laser (0.12±0.07%). Using the automated-shaver and rongeur significantly reduced the toe-region stiffness, while the linear region stiffness was significantly reduced only in the rongeur group. From the MRIs, more homogeneous cavities were seen in the center of the disc when using the automated shaver compared to rongeur, whilst laser ablation resulted in small, localized cavities.Introduction

There is a need for non-radiographic, objective outcome measures for children with Adolescent Idiopathic Scoliosis (AIS). Standing balance and stability is altered in children with AIS. The Margin of Stability (MoS) has been used to compare gait stability in clinical populations. Our objective was to compare the MoS in anterior-posterior (MoSAP) and mediolateral (MoSML) directions in girls with AIS to Controls. Girls with AIS and healthy girls walked at three speeds on an instrumented treadmill wearing retroreflective markers, surrounded by motion capture cameras. The MoSAP/ML was calculated at left and right heel strike. Data was processed in Visual 3D. A two-way ANOVA was used to compare MoSAP/ML between group, speed and the interaction between group and speed. Pearson's correlation coefficient was used to compare the MoS to Cobb angle. Statistical significance was accepted when A priori power analysis suggested 12 participants per group. Three Cases and four Controls were recruited. Girls with AIS all had right-sided main thoracic curves (Lenke type 1a, 61.3° ± 10.0°). MoSAP was significantly bigger for Cases compared to Controls on the left ( Girls with Lenke type 1a AIS are more stable in the AP direction and less stable in the ML direction than Controls during treadmill walking. AP stability increases and ML stability decreases with increasing Cobb angle. This research suggests that the MoS could be used as an outcome measure for children with AIS. Continued work is required to increase the power of this study. Further work could consider these changes during walking overground, measuring an MoS or MoS-like measure using a wearable device, and in different curve types.
Children undergoing posterior spinal fusion (PSF) for neuromuscular and syndromic scoliosis were admitted to the paediatric intensive care (PIC) until about 6 years ago, at which time we created a new unit, a hospital floor-based spinal high-dependency unit-plus (SHDU-plus), in response to frequent bed-shortage cancellations. This study compares postoperative management on PIC with HDU-plus for these non-hospital floor suitable children with syndromic and neuromuscular scoliosis undergoing PSF. Retrospective review of 100 consecutive children with syndromic and neuromuscular scoliosis undergoing PSF between June 2016 and January 2022. Inclusion criteria were: 1) diagnosis of syndromic or neuromuscular scoliosis, 2) underwent PSF, 3) not suitable for immediate postoperative hospital floor-based care. Exclusion criteria were children with significant cardio-respiratory co-morbidity requiring PIC postoperatively. 55 patients were managed postoperatively on PIC and 45 on SHDU-plus. No significant difference between groups was found with respect to age, weight, ASA grade, preoperative Cobb angles, operative duration, number of levels fused and estimated blood loss. 4 patients in the PIC group and 1 in the SHDU-plus group were readmitted back to PIC or HDU following step-down to the hospital floor. Average length of stay was 2 days on PIC and 1 day on SHDU-plus. Average total length of hospital stay was 16.5 days in the PIC group and 10.5 days in the HDU-plus group. 19 (35%) patients developed complications in the PIC group, compared to 18 (40%) in SHDU-plus. Mean specialist unit charge per day was less on SHDU-plus compared with PIC. There were no bed-shortage cancellations in the SHDU-plus group, compared to 11 in the PIC group. For children with neuromuscular or syndromic scoliosis undergoing PSF and deemed not suitable for post-operative care on the hospital floor, creation of a SHDU-plus was associated with fewer readmissions back to PIC or HDU, shorter hospital stays, an equivalent complication rate, significant cost-saving and fewer cancellations. Level of Evidence: Therapeutic Level III.
We previously reported that osteoblasts at the curve apex in adolescent idiopathic scoliosis (AIS) exhibit a differential phenotype, compared to non-curve osteoblasts(1). However, the Hueter-Volkmann principle on vertebral body growth in spinal deformities (2) suggests this could be secondary to altered biomechanics. This study examined whether non-curve osteoblasts subjected to mechanical strain resemble the transcriptomic phenotype of curve apex osteoblasts. Facet spinal tissue was collected perioperatively from three sites, (i) the concave and (ii) convex side at the curve apex and (iii) from outside the curve (non-curve) from six AIS female patients (age 13–18 years; NRES 19/WM/0083). Non-curve osteoblasts were subjected to strain using a 4-point bending device. Osteoblast phenotype was determined by RNA sequencing and bioinformatic pathway analysis. RNAseq revealed that curve apex osteoblasts exhibited a differential transcriptome, with 1014 and 1301 differentially expressed genes (DEGs; p<0.05, fold-change >1.5) between convex/non-curve and concave/non-curve sites respectively. Non-curve osteoblasts subjected to strain showed increased protein expression of the mechanoresponsive biomarkers COX2 and C-Fos. Comparing unstimulated vs strain-induced non-curve osteoblasts, 423 DEGs were identified (p<0.05, fold-change >1.5). Of these DEGs, only 5% and 6% were common to the DEGs found at either side of the curve apex, compared to non-curve cells. Bioinformatic analysis of these strain-induced DEGs revealed a different array of canonical signalling pathways and cellular processes, to those significantly affected in cells at the curve apex. Mechanical strain of AIS osteoblasts in vitro did not induce the differential transcriptomic phenotype of AIS osteoblasts at the curve apex.
A Core Outcome Set (COS) for treatment of adolescent idiopathic scoliosis (AIS) is essential to ensure that the most meaningful outcomes are evaluated and used consistently. Measuring the same outcomes ensures evidence from clinical trials and routine clinical practice of different treatments can be more easily compared and combined, therefore increasing the quality of the evidence base. The SPINE-COS-AYA project aims to develop a gold standard COS which can be used internationally in research and routine clinical practice to evaluate the treatment (surgical and bracing) of AIS. In this qualitative study, the views of adolescents and young adults with AIS (10-25 years of age), their family members and healthcare professionals in a UK region were sought, via interviews, on treatment outcomes. Participants were purposively recruited from a variety of sources including NHS outpatient clinics and social media. Semi-structured interviews were analysed using thematic analysis. Key findings will be presented, to include potential core outcome domains identified by the different subgroups. The core outcome domains identified in this research programme will subsequently form part of an international consensus survey to agree a COS. In future, if the COS is used by healthcare staff and researchers, it will be easier for everyone, including patients and their families, to assess which treatment works best.
Thermal sensors have been used in bracing research as self-reported diaries are inaccurate. Little is known about new low-profile sensors, optimal location within a brace, locational thermal micro-climate and effect of brace lining. Our objective is to Determine an optimal temperature threshold for sensor-measured and true wear time agreement. Identify optimal sensor location. Assess all factors to determine the best sensor option for the Bracing AdoleScent Idiopathic Scoliosis (BASIS) multicentre RCT. Seven Orthotimer and five iButton (DS1925L) sensors were synchronised to record temperature at five-minute intervals. Three healthy participants donned a rigid spinal brace, embedded with both sensors across four anatomical locations (abdomen/axilla/lateral-gluteal/sacral). Universal-coordinated-time wear protocols were performed in/out-doors. Intraclass correlation coefficient (ICC) assessed sensor-measured and true wear time agreement at thresholds 15–36oC. Optimal thresholds, determined by largest ICC estimate: Orthotimer: Abdomen=26oC, axilla=27oC, lateral-gluteal=24.5oC, sacral=22.5oC. iButton: Abdomen=26oC, axilla=27oC, lateral-gluteal=23.5oC, sacral=23.5oC. Warm-up time and error at optimal thresholds increased for moulded sensors covered with 6mm lining. Location: anterior abdominal wall. Excellent reliability and higher optimal thresholds, less likely to be exceeded by ambient temperature; not a pressure area. Sensor: iButton, longer battery life and larger memory than Orthotimer; allows recording at 10 min intervals for life of brace. Orthotimer only able to record every 30 mins, increasing error between true and measured wear time; Orthotimer needs 6-monthly data download. Threshold: 26oC is optimal threshold to balance warm-up and cool-down times for accurately measuring wear time. Sensor should not be covered by lining foam as this significantly prolongs warm-up time.
Less invasive single-rod fusion technique may be indicated in the management of NMS to minimise operative time, blood loss and wound-related complications. This retrospective 12-year cohort study (2008–2020) aims to evaluate and compare the outcomes of this technique to the current standard dual rod technique to determine their safety and efficacy. 28 patients in the single rod group (Mean age = 16.4 [SD ±4.0]) and 30 in the double rod group (Mean age = 16.3 [SD±3.5]). Indications included a minimum 2 year follow period, detailed information on the type of implant and a complete pre- and post-operative imaging and medical records. Baseline demographics, comorbidities, and surgical characteristics were collected. Outcomes assessed included the immediate post-op and final follow up angles and general complications. All outcome analysis was performed using a regression approach. Angles at final follow-up: lumbar (Difference ratio (DR)= 2.60 [95% CI 0.37 – 18.4], p=0.25), thoracic (DR= 1.08 [95% CI 0.19 – 6.28], p=0.92), thoracolumbar (major curve angle) (DR 1.35 [95% CI 0.60 – 3.06], p=0.46) and kyphosis (DR = 0.97 [0.66, 1.42] p=0.86). There was no statistically significant difference, between the two groups, for any of the above angle outcomes as well as for length of surgery, blood loss and complication outcomes. Both single and double rod instrumentation achieves satisfactory and safe deformity correction which is maintained at final follow up. A larger scale study is warranted to further assess these techniques while also conducting a cost-benefit analysis between them.
The lordosis distribution index (LDI) describes distribution of lumbar lordosis, measured as the % of lower lumbar lordosis (L4-S1) compared to global lordosis (L1-S1) with normal value 50–50%. Maldistributed LDI is associated with higher revision in short lumbar fusions, 4 vertebrae1. We hypothesise maldistributed LDI is also associated with mechanical failure in longer fusions. Retrospective review of 29 consecutive ASD patients, aged 55+, undergoing long lumbar fusion, 4 levels, with >3-years follow-up. LDI, pelvic incidence (PI) and sagittal vertical axis (SVA) were measured on pre- and post-op whole spine standing X-rays (Fig A and B). Patients were categorized according to their pelvic incidence (PI) and postoperative LDI: Normal (LDI 50 80), Hypolordotic (LDI < 50), or Hyperlordotic (LDI > 80) and assessed for failure rate compared to normal LDI and PI <60. Mean follow-up 4.5 years. 19 patients had mechanical failures including junctional failure and metalware fracture. PI >60o was associated with higher mechanical failure rates (Chi^2 p<0.05). Hypolordotic LDI was associated with 82% mechanical failure (Chi^2 p<0.001), Hyperlordotic 88% mechanical failure (Chi^2 p<0.001) and Normal 8% mechanical failure (Table 1). Maldistributed LDI, whether Hyperlordotic or Hypolordotic, correlated with 10× greater mechanical failure rate compared to Normal LDI in long fusions. LDI is a useful measurement that should be considered, especially in high PI patients.
The aim of this study is to clarify the implication of ciliary pathway on the onset of the spinal curvature that occurs in Adolescent Idiopathic Scoliosis (AIS) patients through functional studies of two genes: POC5 and TTLL11. Since the genetic implication for AIS is accepted, many association and candidate gene analysis revealed the implication of ciliary genes. The characterisation of these two proteins was assessed by qPCR, WB and immunofluorescence in vitro using control cells and cells derived from AIS patients. The impact of genetic modification of these genes on the functionality of the proteins in vitro and in vivo was analysed in zebrafish model created by CRISPR/Cas9 using microCT and histologic analysis. Our study revealed that mutant cells, for both gene, were less ciliated and the primary cilia was significantly shorter compared to control cells. We also observed a default in cilia glutamylation by immunofluorescence and Western Blot. Moreover, we observed in both zebrafish model, a 3D spine curvature similar to the spinal deformation in AIS. Interestingly, our preliminary results of immunohistology showed a retinal defect, especially at the cone cell layer level. This study strongly supports the implication of the ciliary pathway in the onset of AIS and this is the first time that a mechanism is described for AIS. Indeed, we show that shorter cilia could be less sensitive to environmental factors due to lower glutamylation and result in altered signalling pathway. Identifying the biological mechanism involved is crucial for elucidating AIS pathogenesis.
Surgical site infections following spinal surgery profoundly influence continued treatment, significantly impacting psychological and economic dimensions and clinical outcomes. Its reported incidence varies up to 20%, with the highest incidence amongst neuromuscular scoliosis and metastatic cord compression patients. We describe the first reported biphasic osteoconductive scaffold (Cerament G) with a logarithmic elution profile as a cumulative strategic treatment modality for adjacent spinal surgery infections. All patients who developed surgical site infections following instrumented fusion (May 2021-December 2021) had their demographics (age, sex), type and number of procedures, isolated organism, antibiotics given, comorbidities, and WHO performance status analysed. The infected wound was debrided to healthy planes, samples taken, and Cerament g applied. Thirteen patients were treated for deep SSI following spinal instrumentation and fusion procedures with intraoperative Cerament G application. There were four males and nine females with an average age of 40 ranging between 12 and 87. Nine patients underwent initial surgery for spinal deformity, and four were treated for fractures as index procedure. 77% of infections were attributable to MSSA and Cutibacteriousm acnes; others included Klebsiella, Pseudomonas and Streptococcus and targeted with multimodal cumulative therapy. A WHO performance score improved in 11 patients. In addition, there was no wound leak, and infection was eradicated successfully in 12/13 with a single procedure. This series shows the successful eradication of the infection and improved functional outcomes with Cerament G. However, the low numbers of patients in our series are an essential consideration for the broader applicability of this device.
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.
The aim of this study was to assess the ability of morphological spinal parameters to predict the outcome of bracing in patients with adolescent idiopathic scoliosis (AIS) and to establish a novel supine correction index (SCI) for guiding bracing treatment. Patients with AIS to be treated by bracing were prospectively recruited between December 2016 and 2018, and were followed until brace removal. In all, 207 patients with a mean age at recruitment of 12.8 years (SD 1.2) were enrolled. Cobb angles, supine flexibility, and the rate of in-brace correction were measured and used to predict curve progression at the end of follow-up. The SCI was defined as the ratio between correction rate and flexibility. Receiver operating characteristic (ROC) curve analysis was carried out to assess the optimal thresholds for flexibility, correction rate, and SCI in predicting a higher risk of progression, defined by a change in Cobb angle of ≥ 5° or the need for surgery.Aims

MAGnetic Expansion Control (MAGEC) rods are used in the surgical treatment of children with early onset scoliosis. The magnetically controlled lengthening mechanism enables rod distractions without the need for repeated invasive surgery. The CE certification of these devices was suspended in March 2021 due, primarily, to performance evidence gaps in the documents provided by the manufacturer to regulators and notified bodies. MAGEC rods are therefore not permitted for use in countries requiring CE marking. This was a survey of 18 MAGEC rod surgeons in the UK about their perception of the impact of the CE suspension on the clinical management of their patients. Unsurprisingly, virtually all perceived a negative impact, reflecting the complexity of this patient group. Reassuringly, these surgeons are highly experienced in alternative treatment methods.

Psychoeducative prehabilitation to optimize surgical outcomes is relatively novel in spinal fusion surgery and, like most rehabilitation treatments, they are rarely well specified. Spinal fusion patients experience anxieties perioperatively about pain and immobility, which might prolong hospital length of stay (LOS). The aim of this prospective cohort study was to determine if a Preoperative Spinal Education (POSE) programme, specified using the Rehabilitation Treatment Specification System (RTSS) and designed to normalize expectations and reduce anxieties, was safe and reduced LOS. POSE was offered to 150 prospective patients over ten months (December 2018 to November 2019) Some chose to attend (Attend-POSE) and some did not attend (DNA-POSE). A third independent retrospective group of 150 patients (mean age 57.9 years (SD 14.8), 50.6% female) received surgery prior to POSE (pre-POSE). POSE consisted of an in-person 60-minute education with accompanying literature, specified using the RTSS as psychoeducative treatment components designed to optimize cognitive/affective representations of thoughts/feelings, and normalize anxieties about surgery and its aftermath. Across-group age, sex, median LOS, perioperative complications, and readmission rates were assessed using appropriate statistical tests.Aims

Vertebral body tethering (VBT) is a non-fusion technique to correct scoliosis. It allows correction of scoliosis through growth modulation (GM) by tethering the convex side to allow concave unrestricted growth similar to the hemiepiphysiodesis concept. The other modality is anterior scoliosis correction (ASC) where the tether is able to perform most of the correction immediately where limited growth is expected. We conducted a retrospective analysis of clinical and radiological data of 20 patients aged between 9 and 17 years old, (with a 19 female: 1 male ratio) between January 2014 to December 2016 with a mean five-year follow-up (4 to 7).Aims
Methods
To provide normative data that can assess spinal-related disability and the prevalence of back or leg pain among adults with no spinal conditions in the UK using validated questionnaires. A total of 1,000 participants with equal sex distribution were included and categorized in five age groups: 20 to 29, 30 to 39, 40 to 49, 50 to 59, and 60 to 69 years. Individuals with spinal pathologies were excluded. Participants completed the Scoliosis Research Society-22 (SRS-22r), visual analogue scale (VAS) for back/leg pain, and the EuroQol five-dimension index (EQ-5D/VAS) questionnaires, and disclosed their age, sex, and occupation. They were also categorized in five professional groups: doctors, nurses, allied health professionals, office workers, and manual workers.Aims

With resumption of elective spine surgery services in the UK following the first wave of the COVID-19 pandemic, we conducted a multicentre British Association of Spine Surgeons (BASS) collaborative study to examine the complications and deaths due to COVID-19 at the recovery phase of the pandemic. The aim was to analyze the safety of elective spinal surgery during the pandemic. A prospective observational study was conducted from eight spinal centres for the first month of operating following restoration of elective spine surgery in each individual unit. Primary outcome measure was the 30-day postoperative COVID-19 infection rate. Secondary outcomes analyzed were the 30-day mortality rate, surgical adverse events, medical complications, and length of inpatient stay.Aims

Anchorage of pedicle screw rod instrumentation in the elderly spine with poor bone quality remains challenging. Our study aims to evaluate how the screw bone anchorage is affected by screw design, bone quality, loading conditions, and cementing techniques. Micro-finite element (µFE) models were created from micro-CT (μCT) scans of vertebrae implanted with two types of pedicle screws (L: Ennovate and R: S4). Simulations were conducted for a 10 mm radius region of interest (ROI) around each screw and for a full vertebra (FV) where different cementing scenarios were simulated around the screw tips. Stiffness was calculated in pull-out and anterior bending loads.Aims

Although interlaminar endoscopic lumbar discectomy (IELD) is considered to be less invasive than microscopic lumbar discectomy (MLD) in treatment of lumbar herniated nucleus pulposus, the radiologic change of multifidus muscles by each surgery has rarely been reported. The aim of the present study was to compare the quantitative and qualitative changes of multifidus muscles between two surgical approaches and to analyze the correlation between various parameters of multifidus muscles and long term surgical outcome. 21 patients who received MLD and 18 patients who received IELD in a single tertiary hospital were enrolled and their preoperative, postoperative (≤15 days), and follow-up (≥6 months) MRIs were analyzed. The cross-sectional area (CSA) and fatty degeneration rate (FD) were quantitatively estimated at the level of surgery. The correlations among CSA, FD, body mass index, follow-up visual analogue scale(VAS) and Oswestry Disability Index(ODI) were assessed. Mean intervals of postoperative MRI and follow-up MRI from surgery were 3.0±3.7 days and 14.5±10.7 months, respectively. During the follow-up period, VAS was improved from 7.1±1.3 to 2.1±1.8 in MLD and from 8.2±1.4 to 2.2±1.8 in IELD. In cases of MLD, comparing with preoperative MRI, ipsilateral CSA was significantly increased in postoperative MRI (795.6mm2 vs. 906.5mm2, p<0.01), but it was not significantly different in follow-up MRI (795.6mm2 vs. 814.4mm2, p=1.00). However, in case of IELD, the ipsilateral CSAs in preoperative, postoperative, and follow-up periods were 892.0 mm2, 909.3 mm2, and 900.3 mm2, respectively. These changes were not significant over time (p=0.691). The ipsilateral FDs were not significantly changed between preoperative and follow-up periods in both MLD (21.4% vs. 20.9%, p=0.81) and IELD groups (23.5% vs. 21.8%, p=0.19). The increment of ipsilateral CSA had significant correlations with follow-up ODI (r=−0.368, p=0.02). Comparing with IELD, MLD induced more surgical trauma on multifidus muscle in postoperative period, but the muscular damage was recovered in follow-up period. IELD can minimize surgical trauma on multifidus muscle showing similar pain relief as MLD. Favorable surgical outcome in follow-up period may be related to increment of multifidus muscle volume. Figure 1 (A-C) The multifidus muscles in preoperative, postoperative, and follow-up periods, respectively, in patient with MLD. Comparing with preoperative period, the CSA of right multifidus muscle (ipsilateral side) was increased in postoperative period, but recovered in follow-up period. (D-F) The multifidus muscle in preoperative, postoperative, and follow-up periods, respectively, in patient with IELD. The CSA of left multifidus muscles (ipsilateral side) was not significantly changed over time. Comparing preoperative MRIs with follow-up MRIs, the FDs of multifidus muscles were not significantly changed regardless of surgical technique. Figure 2 The CSA was measured by marking region of interest (ROI) and FD was measured by calculating the rate of pixels beyond the threshold in ROI. All measurements were performed using ImageJ software (version 1.52a, National Institutes of Health, Bethesda, Maryland, USA). For any figures or tables, please contact the authors directly.
The British Spinal Registry (BSR) is a web-based database commissioned by the British Association of Spine Surgeons (BASS) in the UK. It allows auditing of spinal surgery outcomes, patient's safety and overall experience. The clinical data include patient's demographics which is entered into the Registry by medical staff, as well as patient-reported outcome measures (PROM) that is submitted to the Registry by the patient themselves at different time periods post-operatively. It has the ability to register Device and Implants as well as co-ordinate multicentre research. This study is to identify both the staff and patient compliance regarding to data submissions to the BSR at St. George's Hospital NHS Trust. Retrospective analysis of the BSR data for all spinal surgeries that was performed at SGH by the three Complex Spinal Surgery Consultants between 1st January 2017 to 31st December 2018. This study period allowed up to 12 months PROM data analysis. Staff and Patient compliance were analysed separately depend on the data they submitted.Introduction

Scoliosis surgery is a life-changing procedure, but not devoid of perioperative complications. Often patients' scoring systems do not cover their real-life needs, including return to pre-surgery activity. Return to school, physical education (PE) is an important indirect marker of recovery. Although anterior spinal fusion (ASF) may have advantages, compared to posterior spinal fusion (PSF), because of motion-saved segments, there is a paucity of literature about post-operative return to school/PE in the compared groups. To determine the recovery time for patients with scoliosis who underwent anterior spinal fusion (ASF) and posterior spinal fusion (PSF)Introduction
Aim
Degenerative spondylosis (DS) represents a challenging condition to diagnose and treat. There are multiple modalities to investigate DS including X-ray, MRI and CT, but symptoms may not be equivocal to DS to support the clinical findings. The investigation of metastases commonly utilises SPECT/CT for identification of areas of increased osteoblastic activity to denote disease. The aim of the study was to analyse the prevalence of asymptomatic DS in a consecutive hospital cohort of oncology patients who had SPECT/CT for investigation of metastases. Oncology patients who underwent SPECT/CT at St. George's Hospital were analysed between 2015–2019. Exclusion criteria: back pain, inflammatory disorders, metastases, trauma, infection. Radiology reports were examined for DS and anatomical distribution of tracer uptake.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. Retrospective review of oligometastatic spinal disease at a supra-regional centre between 2017 and 2021. Demographics, operative course, complications and Instrument type are examined.Introduction

Missile injuries are very serious injuries particularly in the cervical region. They are classified into high and low missile injuries when it involves the cervical spine. In modern guerrilla warfare, one must be aware of ballistic pathology with bullets as well as from explosives. In particular, improvised explosive devices commonly known as IED's play a new and important pathophysiology whether they are suicided vests or roadside bombs. They usually produce severe or lethal injuries and serious neurovascular deficit is frequent. We present the details of 40 patients with local experience on how to handle serious penetrating cervical missile injuries. All cases were collected from the record of Basrah University Hospital, Iraq. Healthy military gentlemen with ages ranging between 20–35 years were included.Introduction

Patients with metastatic spinal cord compression (MSCC) or unstable spinal lesions warrant early surgical consultation. In multiple myeloma, chemotherapy and radiotherapy have the potential to decompress the spinal canal effectively in the presence of epidural lesions. Mechanical stability conferred by bracing may potentiate intraosseous and extraosseous bone formation, thus increasing spinal stability. This study aims to review the role of non-operative management in myeloma patients with a high degree of spinal instability, in a specialist tertiary centre. Retrospective analysis of a prospectively collected database of 83 patients with unstable myelomatous lesions of the spine, defined by a Spinal Instability Neoplastic Score (SINS) of 13–18. Data collected include patient demographics, systemic treatment, neurological status, radiological presence of cord compression, most unstable vertebral level and presence of intraosseous and extraosseous bone formation. Post-treatment scores were calculated based on follow-up imaging which was carried out at 2 weeks for cord compression and 12 weeks for spinal instability. A paired t-test was used to identify any significant difference between pre- and post-treatment SINS and linear regression was used to assess the association between variables and the change in SINS.Introduction

Thoracic wall surgery can cause severe pain and inhibition of coughing with effects. (1) Various local anaesthetic (LA) techniques have been tried successfully to mitigate the use of opioids alone. We believe this is the first time that a serratus plane block using an epidural catheter (SABER)has been studied in anterior spinal fusion (ASF) procedures. Our aim was to ascertain how it would affect ASF compared to gold standard posterior spinal fusion (PSF) surgery. We identified 43 patients from the years 2017 to 2019. 24 had ASF and 19 had PSF. Detailed data were collected on local anaesthetic infusion (LAI) SaBER, mean pain scores(MPS), morphine, chirocaine usage and hospital length of stay (HLOS). We divided the patients into 4 groups: Short PSF (SPSF), Long PSF (LPSF), Thoracic anterior fusion (TA) and Thoracolumbar anterior fusion (TLA) surgery. 4 patients in the SPSF and 4 in the LPSF group had LAI because they had a costoplasty. All patients in the anterior group had SaBER.Introduction

Tomita En-bloc spondylectomy (TES) of L5 is one of the most challenging spinal surgical techniques. A 42-year-old female was referred with low back pain and L5 radiculopathy with background of right shoulder excision of liposarcoma. CT-PET confirmed a solitary L5 oligometastasis. MRI showed thecal sac indentation and therefore was not suitable for stereotactic ablative radiotherapy (SABR) alone. First Stage: Carbon fibre pedicle screws were planned from L2 to S2AI-Pelvis, aligned to her patient-specific rods. Custom 3D-printed navigation guides were used to overcome challenging limitations of carbon instruments. Radiofrequency ablation (RFA) of L5 pedicles prior to osteotomy was performed to prevent sarcoma cell seeding. Microscope-assisted thecal sac-tumour separation and L5 nerve root dissection was performed. Novel surgical navigation of the ultrasonic bone cutter assisted inferior L4 and superior S1 endplate osteotomies. Second stage: We performed a vascular-assisted retroperitoneal approach to L4-S1 with protection of the great vessels. Completion of osteotomies at L4 and S1 to en-bloc L5: (L4 inferior endplate, L4/5 disc, L5 body, L5/S1 disc and S1 superior endplate). Anterior reconstruction used an expandable PEEK cage obviating the need for a third posterior stage. Reinforced with a patient-specific carbon plate L4-S1 promontory. Sacrifice of left L5 nerve root undertaken.Introduction
Planning Methodology
Thoracolumbar injury classification systems are not used or researched extensively in paediatric population yet. This systematic review aims to explore the validity and reliability of the two main thoracolumbar injury classification systems in the paediatric population (age ≤ 18). It also aims to explore the transferability of adult classification systems to paediatrics. The Thoracolumbar Injury Classification System (TLICS) published in 2005 and the AO Spine published in 2013 were assessed in this paper because they both provide guidance for the assessment of the severity of an injury and recommend management strategies. A literature search was conducted on the following databases: Medline, EMBASE, Ovid during the period November 2020 to December 2020 for studies looking at the reliability and validity of the TLICS and AO Spine classification systems in paediatric population. Data on validity (to what extent TLICS/ AO Spine recommended treatment matched the actual treatment) and reliability (inter-rater and intra-rater reliability) was extracted. There is an “almost perfect validity” for TLICS. There is a “strong association” between the validity of TLICS and AO Spine. The intra-rater reliability is “moderate” for TLICS and “substantial” for AO Spine. The intra-rater reliability is “substantial” for TLICS and “almost perfect” for AO Spine. The six studies show a good overall validity and reliability for the application of TLICS and AO Spine in pediatric thoracolumbar fractures. However, implication of treatment and anatomical differences of the growing spine should be explored in detail. Therefore, AO Spine can be used in absence of any other classification system for paediatrics.
The advent of EOS imaging has offered clinicians the opportunity to image the whole skeleton in the anatomical standing position with a smaller radiation dose than standard spine roentgenograms. It is known as the fifth modality of imaging. Current NICE guidelines do not recommend EOS scans over x-rays citing: “The evidence indicated insufficient patient benefit in terms of radiation dose reduction and increased throughput to justify its cost”. We retrospectively reviewed 103 adult and 103 paediatric EOS scans of standing whole spines including shoulders and pelvis for those undergoing investigation for spinal deformity in a tertiary spinal centre in the UK. We matched this against a retrospective control group of 103 adults and 103 children who underwent traditional roentgenograms whole spine imaging at the same centre during the same timeframe. We aimed to compare the average radiation dose of AP and lateral images between the two modalities. We utilised a validated lifetime risk of cancer calculator (Background

Traditionally correction of idiopathic paediatric scoliosis is done by hybrid fixation. This involves a judicious combination of mono-axial and poly-axial screw constructs. This has inherent perceived advantages with better deformity correction and maintaining alignment without loss of correction over time. Single centre retrospective review of prospective collected data on the radiological analysis of idiopathic paediatric scoliosis corrections. The study compared hybrid screw constructs (poly-axial & mono-axial) to all poly-axial screw constructs over 28 months.Introduction

Microdiscectomy is the most commonly performed spine surgery in the world. Due to its technical simplicity and low complication rate, this was the first spine surgical procedure transitioning for one-day surgery. However, the economic assessment of this outpatient transition was never performed and the question on the real impact in the burden of spine care remains. This economic study aims to access the cost-utility of outpatient lumbar microdiscectomy when compared with the inpatient procedure. To do so, a cost-utility study was performed, adopting the hospital perspective. Direct medical costs were retrieved from the assessment of 20 patients undergoing outpatient lumbar microdiscectomy and 20 undergoing inpatient lumbar microdiscectomy, from a in a Portuguese NHS hospital. Utilities were calculated with quality-adjusted life-years were derived from Oswestry Disability Index values (ODI). ODI was assessed prospectively in outpatients in pre and 3- and 6-month post-operative evaluations. Inpatient ODI data were estimated from a meta-analysis. both probabilistic and deterministic sensitivity analyses were performed and incremental cost-effectiveness ratio (ICER) calculated. A willingness to pay (WTP) threshold of €60000/QALY gained with inpatient procedure was defined. Out results showed that inpatient procedure was cost-saving in all models tested. At 3-month assessment ICER ranged from €135753 to €345755/QALY, higher than the predefined WTP. At 6-month costs were lower and utilities were higher in outpatient, overpowering the inpatient procedure. Probabilistic sensitivity analysis showed that in 65% to 73% of simulations outpatient was the better option. The savings with outpatient were about 55% of inpatient values, with similar utility scores. No 30-day readmissions were recorded in either group. The mean admission time in inpatient group was 2.5 days. Since there is an overall agreement among spine surgeons that an uncomplicated inpatient MD would only need a one-day admission, an analysis reducing inpatient admission time for one day was also performed and outpatient remained cost-effective. In conclusion, as the first economic study on cost-utility of outpatient lumbar microdiscectomy, this study showed a significant reduction in costs, with a similar clinical outcome, proving this outpatient transition as cost-effective
Pulmonary Tuberculosis (TB) can be detected by sputum cultures. However, Extra Pulmonary Spinal Tuberculosis (EPSTB), diagnosis is challenging as it relies on retrieving a sample. It is usually discovered in the late stages of presentation due to its slow onset and vague early presentation. Difficulty in detecting Mycobacterium Tuberculosis bacteria from specimens is well documented and therefore often leads to culture negative results. Diagnostic imaging is helpful to initiate empirical therapy, but growing incidence of multidrug resistant TB adds further challenges. A retrospective analysis of cases from the Infectious Disease (ID) database with Extra Pulmonary Tuberculosis (EPTB) between 1st of January 2015 to 31st of January. Two groups were compared 1) Culture Negative TB (CNTB) and 2) Culture Positive TB (CPTB). Audit number wasIntroduction

Partial facetectomies with pedicle screw instrumentation is widespread and a well described technique for achieving posterior correction of scoliosis. Newton et al. first described the use of the UBS in the posterior correction of AIS in 2014. The aim of this study was to compare the effectiveness of the UBSPO in achieving posterior correction in Type1 AIS as compared to the traditional partial facetectomies. Aim of this study was to assess the effectiveness of USBPO in achieving posterior correction in Type 1 AIS as compared to partial facetectomies. A retrospective review of 40 patients with type 1 AIS who had undergone a posterior correction of scoliosis between 2010 and 2016 was performed. Group A (n=20) consisted of consecutive patients that had partial facetectomies while Group B (n=20) consisted of consecutive patients having UBSPO. Both groups were matched for demographic parameters. Pre and post-operative radiographic parameters and operative data in both groups were compared. The Mann-Whitney U test was used for statistical analysis.Background

1312 patients with idiopathic scoliosis completed the ScolioGold Body Image Questionnaire (SBIQ) before and after a course of intensive PSSE treatment. A paired T-test compared the patient's perception of Body image. Mean age was 24.7 with a range of 6 to 83 years old (<18 = 687; >18 = 625), female = 1061, male = 251). Pre-treatment average was 5.3 (SD=2.07), which improved to 2.8 after treatment (SD=1.8). The difference of 2.6 was statistically significant (p<0.005). Pre-treatment, the patients in the children group scored 4.67, which was significantly lower than the adult group score of 6.32. On average, the children improved their scores by 2.48 to 2.19 which was statistically significant (p=0.000). The adults improved their scores by 2.81 to 3.51 which was statistically significant (p=0.000). On average patients with mild (11° to 25° Cobb angles) and moderate (26° to 50° Cobb angles) curvatures achieved a larger improvement compared to patients with severe curvatures (>50° Cobb angles). This difference of 0.35 was statistically significant (n=641, p<0.05). There were significant improvements in the total SBIQ scores before and after treatment in both the child and adult groups with mild to severe curvatures after an intensive course of PSSE treatment. This shows that intensive PSSE treatment can improve scoliotic patients' self-image, therefore addressing aspects of their psychosocial well-being.
The aim of this study was to compare the treatment ouctomes of severe idiopathic scoliosis (IS) (>90 degrees) using the staged surgery with initial limited internal distraction and typical IS treated using segmental pedicle screw instrumentation. We hypothesized that staged surgical treatment of severe scoliosis would improve more HRQoL and pulmonary function (PF) as compared with posterior spinal fusion (PSF) for typical IS curves. It was a retrospective review of a consecutive series of 60 IS, severe group (SG) vs. moderate group (MG) with min. 2 years of follow up (FU). The mean preoperative major curve (MC) was 120° and thoracic kyphosis (TK) was 80° for the SG and 54° and 17° for the MG, respectively (p<0.001). The MC was corrected to 58° and TK to 32° for the SG; the MC to 26° and TK to 14°, for the MG, respectively (p<0.001). The mean preoperative AVT was 8.9 cm and improved to 2.8 cm at the final FU for the SG and from 6.5 cm to 2.2 cm at the final FU for the MG (p<0.001). At baseline, the FVC% & FEV1% values were significant different between the two groups (41.5% vs. 83%, p <0.001) & (41.6% vs. 77%, p <0.001). Compared the baseline for SG vs. the values at 2-year FU the FVC % values were (41.5% vs. 66.5%, p <0.001), and the baseline for MG vs. the values at 2-year FU, the FEV1 values were (77% vs. 81%, NS). At last FU, no complications were reported. Gradual traction with complicity of multilevel Ponte's osteotomies and neuromonitoring followed by staged pedicle screws instrumentation in severe IS proved to be a safe and effective method improving spinal deformity (52% correction), PF (improved percentage of predicted forced vital capacity by 49%), and health-related quality and allows to achieve progressive curve correction with no neurologic complications associated to more aggressive one-stage surgeries.
