Aims. The British Spine Registry (BSR) was introduced in May 2012 to be used as a web-based database for spinal surgeries carried out across the UK. Use of this database has been encouraged but not compulsory, which has led to a variable level of engagement in the UK. In 2019 NHS England and NHS Improvement introduced a new Best Practice Tariff (BPT) to encourage input of spinal surgical data on the BSR. The aim of our study was to assess the impact of the spinal BPT on compliance with the recording of surgical data on the BSR. Methods. A retrospective review of data was performed at a tertiary spinal centre between 2018 to 2020. Data were collated from electronic patient records, theatre operating lists, and trust-specific BSR data. Information from the BSR included operative procedures (mandatory), patient consent, email addresses, and demographic details. We also identified Healthcare Resource Groups (HRGs) which qualified for BPT. Results. A total of 3,587 patients were included in our study. Of these, 1,684 patients were eligible for BPT. Between 2018 and 2019 269/974 (28%) records were complete on the BSR for those that would be eligible for BPT. Following introduction of BPT in 2019, 671/710 (95%) records were complete having filled in the mandatory data (p < 0.001). Patient consent to data collection also improved from 62% to 93%. Email details were present in 43% of patients compared with 68% following BPT introduction. Conclusion. Our study found that following the introduction of a BPT, there was a statistically significant improvement in BSR record completion compliance in our unit. The BPT offers a financial incentive which can help generate further income for trusts. National data input into the BSR is important to assess patient outcome following spinal surgery. The BSR can also aid future research in spinal surgery. Cite this article: Bone Jt Open 2021;2-3:198–201

To assess concordance between hospital coding and clinician coding for patients undergoing spinal instrumentation procedures and determine if our coding systems result in accurate financial reimbursement from the primary care trust (PCT). We conducted a one year retrospective review of 41 patients who underwent spinal instrumentation procedures. Data collected from IT systems included: operation description, clinician procedure code, hospital procedure code, Hospital Health Resource grouping (HRG), clinician HRG, instrumentation costs and PCT reimbursement fees. From this data we compared coding based re-imbursement fees and actual surgical costs, taking into account exact instrumentation prices. In all cases the primary hospital and clinician coding values differed. Using the clinician code would have altered the HRG group in 16 patients. Using solely clinician coding would have generated less financial reimbursement than using hospital coding. In 23 patients undergoing complex spinal procedures, instrumentation costs represented a significant proportion of the final fee obtained from the PCT, thus leaving a small proportion for the associated hospital stay costs. This suggests instrumentation costs are inadequately reimbursed from the PCT. Hospital coding appears more accurate than clinician coding and results in greater financial reimbursement. On the whole, we found there to be insufficient reimbursement from the PCT. The variable and sometimes substantial cost of spinal instrumentation procedures results in inadequate reimbursement for many procedures. We feel the payment by results (PBR) scheme is suboptimal for such procedures and adequate reimbursement can only be achieved by direct billing on an individual case basis

Background. Mesenchymal stem cells (MSCs) are undergoing evaluation as a potential new therapy for immune and inflammatory-mediated conditions such as IVD degeneration (IDD). Both adipose (ASCs) and bone-marrow (BMSCs) derived MSCs have been widely used in this regard. The optimal tissue source and expansion conditions required to exploit the regenerative capacity of these cells are not yet fully elucidated. In addition the phenotypic response of transplanted cells to the disease environment is not well understood. In this study, ASCs and BMSCs were exposed to a combination of hypoxic conditioning and selected inflammatory mediators, conditions that mimic the microenvironment of the degenerate IVD, in an effort to understand their therapeutic potency for in vivo administration. Methods and Results. Donor-matched ASCs and MSCs were pre-conditioned with either IL-1β (10ng/ml) or TNFα (10ng/ml) for 48 hours under hypoxic conditions (5% O. 2. ). Conditioned media was collected and 45 different immunomodulatory proteins were analysed using human magnetic Luminex® assay. Secreted levels of several key cytokines and chemokines, both pro- and anti-inflammatory, were significantly upregulated in ASCs and BMSCs following the conditioning regime. Under all conditions tested, ASCs expressed significantly higher levels of IL-4, IL-6, IL-10, IL-12, TGF-α, and GCSF compared to BMSCs. Pre-conditioning with TNFα resulted in significantly higher levels of IL-10 while preconditioning with IL-1β resulted in higher levels of IL-6, IL-12 and GCSF. Conclusion. These data suggest that pre-conditioned ASCs may have enhanced therapeutic potential in modulating IVD repair through the increased release of trophic factors that play a role in immunomodulation.

Aims

The aim of this study was to compare outcomes after growth-friendly treatment for early-onset scoliosis (EOS) between patients with skeletal dysplasias versus those with other syndromes.

Introduction. Intervertebral disc degeneration (IVDD) associated with low back pain is a major contributor to global disability. Current treatments are poorly efficient in the long-term resulting in medical complications. Therefore, minimally invasive injectable therapies are required to repopulate damaged tissues and aid regeneration. Among injectable biomaterials, self-assembling peptide hydrogels (SAPHs) represent potential candidates as 3D cell carriers. Moreover, the advent of graphene-related materials has opened the route for the fabrication of graphene-containing hydrogel nanocomposites to direct cellular fate. Here, we incorporated graphene oxide (GO) within a SAPH to develop a biocompatible and injectable hydrogel to be used as cell carrier to treat IVDD. Methods and results. Hydrogel morphology and mechanical properties have been investigated showing high mechanical properties (G'=12kPa) comparable with human native nucleus pulposus (NP) tissue (G'=10kPa), along with ease of handling and injectability in dry and body fluid conditions. Hydrogel nanocomposites resulted biocompatible for the encapsulation of bovine NP cells, showing higher viability (>80%) and metabolic activity in 3D cell culture over 7 days, compared to GO-free hydrogels. Moreover, GO has demonstrated to bind TGF-β3 biomolecules with high efficiency, suggesting the use of GO as local reservoir of growth factors within the injected hydrogel to promote extracellular matrix deposition and tissue repair. Conclusions. Our results show that incorporation of GO within the SAPH improves cell viability and metabolic activity. Furthermore, its tissue-mimicking mechanical properties and chemical tunability make it a promising candidate as injectable carrier of NP cells for the treatment of IVDD.

Aims. The aims of this study were to investigate whether 1) multispecialist tertiary intervention for complex spinal pain lead to reductions in spine-related healthcare costs and 2) baseline characteristics are related to health care consuming costs. Patients and methods. A cost study in a natural prospective cohort was carried out to investigate healthcare data of patients admitted to the Groningen Spine Center (GSC) ranging from two years prior to referral until two year after discharge. GSC intervention consisted of a multi-professional and -specialist based diagnosis and treatment. Patients (18 and 80 years) were included, suffering from specific as well as multifactorial spinal pain. Clinical data was merged with Health Care Insurance data and included questionnaires on demographics, work, pain, disability, quality of life and psychosocial functioning. Univariable (paired sample t-tests) and multivariable analyses (pooled OLS Regression and fixed effects models) were carried out. Results. Included were 997 patients (mean age 52 years) filing a total of 700.533 health care declarations. The findings suggest that the intervention had a significant negative effect on spine-related healthcare costs (predominantly on medical specialist and allied care). Reduction in healthcare costs after treatment was predicted by lower age, lower duration, lower BMI, high education, high job satisfaction, low physical workload, high mental health, better coping, lower pain intensity, high EQ-5D score and low financial worries at baseline (all p<0.01). Conclusion. This observational study showed that spine-related healthcare consuming can be effectively reduced after tertiary multi-specialist intervention for patients with complex spinal pain. The results are robust when controlling for background characteristics and are unlikely to be driven by regression to the mean. No conflicts of interest. No funding obtained

Aims

Historically, patients undergoing surgery for adolescent idiopathic scoliosis (AIS) have been nursed postoperatively in a critical care (CC) setting because of the challenges posed by prone positioning, extensive exposures, prolonged operating times, significant blood loss, major intraoperative fluid shifts, cardiopulmonary complications, and difficulty in postoperative pain management. The primary aim of this paper was to determine whether a scoring system, which uses Cobb angle, forced vital capacity (FVC), forced expiratory volume in one second (FEV1), and number of levels to be fused, is a valid method of predicting the need for postoperative critical care in AIS patients who are to undergo scoliosis correction with posterior spinal fusion (PSF).

Aims

The number of patients undergoing surgery for degenerative cervical radiculopathy has increased. In many countries, public hospitals have limited capacity. This has resulted in long waiting times for elective treatment and a need for supplementary private healthcare. It is uncertain whether the management of patients and the outcome of treatment are equivalent in public and private hospitals. The aim of this study was to compare the management and patient-reported outcomes among patients who underwent surgery for degenerative cervical radiculopathy in public and private hospitals in Norway, and to assess whether the effectiveness of the treatment was equivalent.

Aims

The aim of this study was to determine whether early surgical treatment results in better neurological recovery 12 months after injury than late surgical treatment in patients with acute traumatic spinal cord injury (tSCI).

Background. Surgical patients have cost the NHS 1.3 billion GBP from 1995. Spinal pathologies can present diagnostic challenges, and the consequences of delayed diagnosis or surgical complications can be devastating and so creating high indemnity costs. We aim to highlight the spinal associated litigation patterns within the United Kingdom. Method. Data was obtained from the NHS Litigation Authority from 2002 to 2010. Result. From 236 claims, 144 were related to trauma or acute diagnostic issues and 92 from elective surgery. The financial burden to the NHS came to 60.5 million GBP. Of this sum 42.8 million GBP were paid in damages, and the remaining 29% in legal costs. The financial costs were similar for trauma and elective cases. The most frequent cause of successful litigation for trauma were, missed fractures(41.7%), missed cauda equina(23.6%) and spinal infection(11.8%). The emergency department(43.8%), orthopaedic surgery(28.5%) and Medicine(13.9%) bore the brunt of the claims. For elective surgery, Spinal Damage(19.8%), failure in Post-Operative Care(15.4%), Infection(11%) and Wrong Level Surgery, Cauda Equina and Surgical Failure(9.9% each). were likely to result in a successful claim, and the litigation burden was felt by the orthopaedic(60.4%), Neurosurgery(18.7%) and other surgical disciplines(11%). Conclusion. Acute spinal fractures, cord compression and infection should be considered in patients in the emergency department setting, with appropriate examination and investigations for uncertainty. A lack of awareness of at risk cases increases the likelihood of a pay-out and sums involved. For elective spinal surgery, a failure in the consenting process and the technical skill of the surgeon are likely to result in a pay-out. A failure to identify post-operative complications such as infection and thromboembolism are also indefensible. Protecting patients intra-operatively and maintaining high technical expertise and vigilance post-operatively in an adequately consented patient may decrease litigation rates

Background and purpose of the study. Patients with sciatica experience high levels of disability and poor outcomes and treatment has demonstrated, at best, only modest success. To be effective, management strategies must be informed by patients' perceptions about ‘what matters’ about experiencing this condition. The aim of this paper is to explore the lived experience of sciatica and to consider the implications for clinical practice. Methods and results. In this qualitative study, based on the principles of interpretative phenomenological analysis, 14 participants with a clinical presentation of sciatica of likely nerve root origin were purposively recruited from an NHS, Primary Care Musculoskeletal Service in the UK. Individual, semi-structured interviews were used to collect data, which were audio-recorded and transcribed verbatim. Data were managed using a framework approach and analysed thematically. Sciatica was experienced as a protracted journey of acute exacerbations of uncontrolled and incapacitating symptoms that were overwhelming and difficult to make sense of. Adversely affecting almost all aspects of life, participants struggled to maintain their physical, functional and financial independence; their important relationships; social networks and the roles and activities that provided joy and purpose. The impact of sciatica was a ‘life on hold’; an altered sense of self and an uncertain future. For three participants, the experience of sciatica was sufficiently distressing for them to contemplate suicide. Conclusions. This paper reveals the severity and devastating impact of the symptoms and effects of sciatica. Important practice and research implications have been identified regarding managing symptoms and the need to align treatment strategies with patients' complex and multifaceted needs.

Background. Advances in surgical and anesthetic technique have resulted in a reducing length of stay for lumbar decompression, with the first day case procedure published in the literature in 1980. Current evidence suggests day case surgery is associated with improved patient satisfaction, faster recovery, reduced infection rates and financial savings. Following the introduction of a locally agreed day case protocol for lumbar microdiscectomy, we reviewed our 30-day postoperative complication rates. Aims. To review postoperative complication rates for patients who underwent day case primary lumbar microdiscectomy. Methods. We studied all patients that met a locally agreed day case protocol for lumbar microdiscectomy and were operated upon between 1. st. March 2013 and 31. st. December 2015. Results. 134 patients underwent primary day case microdiscectomy (70 males, 64 females). The cohort had a mean age of 41 years (16–82). 96% (n=129) were single level procedures, 93% were unilateral (n=125). 81% (n=109) took place at either L4/L5 or L5/S1. All patients were discharged on the same day as admission and operation. 3% (n=4) of patients re-presented to hospital within 30 days of which 75% (n=3) were reviewed and discharged from the emergency department within 4 hours, following a satisfactory clinical review. One patient required an inpatient stay for a washout of a superficial postoperative infection. Conclusion. This study demonstrates that with adherence to robust listing and discharge protocols, day case lumbar microdiscectomy can be safely performed. Our 30-day postoperative complication rate of under 1% is comparable to that of traditional inpatient primary lumbar microdiscectomy. No conflicts of interest. No funding obtained

Aims

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.

Aims

The aim of this study was to compare the clinical and radiological outcomes of patients with early-onset scoliosis (EOS), who had undergone spinal fusion after distraction-based spinal growth modulation using either traditional growing rods (TGRs) or magnetically controlled growing rods (MCGRs).

Purposes of Study and Background. This study investigates the role of the patient and the therapeutic relationship with their medical practitioner in resolving CLBP (chronic low back pain). Many cases of chronic pain persist due to the stress response. The body is equipped with natural self-healing mechanisms that must be activated by the patient. This needs facilitation by someone trained to engage the patient in this process. Evidence shows that conventional medication; surgery and physical rehabilitation do not always resolve chronic pain. To ensure that the stress response doesn't sabotage biomedical intervention the patient may need to address any problems obstructing a healthy lifestyle. This means supporting healthy relationships, and good health in other areas such as: professional life, financial matters, beliefs and creativity. Summary of Methods used and Results. Recent Case Studies are described where patients presented with severe CLBP. The Roland Morris Low Back Pain Disability Questionnaire was used to measure outcomes. Treatment included education about the ANS (autonomic nervous system); an active health plan in which the patient takes responsibility for their own healing; and movement guidelines to support the parasympathetic NS. The results show a significant pain reduction and increase in mobility. Conclusion. In these cases conventional medical intervention did not resolve CLBP. These and similar cases during the past 12 years illustrate that this treatment procedure can reduce or eliminate CLBP. Recent research about how stress influences chronic pain may explain these results. More research is needed to investigate the relationship between the ANS and chronic pain, and the implications for the therapeutic relationship.

The prevalence of degenerative spondylolisthesis (DS) increases with age. With an ageing population there will be increasing demands for adult deformity surgery, with associated significant financial and complication costs. The prevalence of lytic spondylolisthesis (LS) is 6–8%. Our clinical observation is that it is extremely rare to see LS in the presence of DS and therefore the objective was to formally describe the prevalence of LS in combination with DS to assess the hypothesis that 6–8% of patients with DS should also have LS. If this is not the case it may further our understanding of the pathogenesis of DS, which could aid in future prevention or treatment. A retrospective review of erect lateral lumbar radiographs demonstrating lumbar spondylolisthesis was performed. Radiographs were identified and analysed on the hospital Synapse Picture Archiving and Communication System (PACS). Search criteria were radiographs requested by primary care and patients aged over 60. 101 patients with spondylolisthesis were identified. 89% were requested for back or leg pain. There were 89 patients with DS (69.7% women) and 12 with LS (83% men). The average age of DS and LS patient was 75 and 70 respectively (not significant). There were no cases found with both DS and LS. This was significantly different to the expected amount of 6% (p=0.03). The level of DS was at L3/4 in 11.2% (n=10), L4/5 in 79.8% (n=71) and L5/S1 in 16.9% (n=15). 2 levels were involved in 7 patients. 94.4% (n=84) demonstrated a Meyerding grade 1 slip and 5.6% (n=5) grade 2 slip. For LS the slipped level was at L5/S1 in all cases. 66.7% (n=8) had a grade 1 slip and 33.3% (n=4) a grade 2 slip. We found no cases of lytic spondylolisthesis in the presence of degenerative spondylolisthesis. We hypothesis that the presence of spondylolysis or lytic spondylolisthesis may be protective against development of degenerative spondylolisthesis. More work is needed to explore this further

To describe the development of a system of referral, initial data acquisition and subsequent database recording and outcome reporting for metastatic spinal cord compression. Deficiencies in the literature identified by the NICE GDG for MSCC for research were compared with our original database and modifications made to ensure prospective collection of currently recognised and some proposed relevant factors. In addition modifications were made to ensure that all NICE implementation audit data and “target “ data are recorded and can be seamlessly transferred to necessary destinations. This generates standardised reports of the presentation, management and longitudinal interval outcomes including analogue pain scales, analgesic requirement, neurological function, Karnofsky performance indices, Euroquols, and ODIs. It includes pretreatment prognostic indices (updated 2005 Tokuhashi scores) relevant to treatment selection and scale of surgical intervention. Outcomes can be subclassified by type of intervention relative to clinical status at intervention. In house live assessment has revealed some reducing minor operational flaws and initial external assessment is current. A comprehensive information system and treatment guide for this increasing group has been developed and is evolving. Common adoption would facilitate earlier recognition and optimise treatment to diminish the high human and financial cost of MSCC. Currently networks are setting up NSSGs and for this process to be enhanced and to avoid costly duplication adoption of this system modified following peer review is suggested

A literature review of bone graft substitutes for spinal fusion was undertaken from peer reviewed journals to form a basis for guidelines on their clinical use. A PubMed search of peer reviewed journals between Jan 1960 and Dec 2009 for clinical trials of bone graft substitutes in spinal fusion was performed. Emphasis was placed on RCTs. Small and duplicated RCTs were excluded. If no RCTs were available the next best clinical evidence was assessed. Data were extracted for fusion rates and complications. Of 929 potential spinal fusion studies, 7 RCTs met the inclusion criteria for BMP-2, 3 for BMP-7, 2 for Tricalcium Phosphate and 1 for Tricalcium Phosphate/Hydroxyapatite (TCP/HA). No clinical RCTs were found for Demineralised Bone Matrix (DBM), Calcium Sulphate or Calcium Silicate. There is strong evidence that BMP-2 with TCP/HA achieves similar or higher spinal fusion rates than autograft alone. BMP-7 achieved similar results to autograft. 3 RCTs support the use of TCP or TCP/HA and autograft as a graft extender with similar results to autograft alone. The best clinical evidence to support the use of DBMs are case control studies. The osteoinductive potential of DBM appears to be very low however. There are no clinical studies to support the use of Calcium Silicate. The current literature supports the use of BMP-2 with HA/TCP as a graft substitute. TCP or HA/TCP with Autograft is supported as a graft extender. There is not enough clinical evidence to support other bone graft substitutes. This study did not require ethics approval and no financial support was received

To evaluate the cost-effectiveness IDET relative to circumferential lumbar fusion with femoral ring allograft (FRA). Cost-effectiveness analysis. Patient-level data were available for patients with discogenic low back pain treated with FRA (n=37) in a randomized trial of FRA vs. titanium cage, and for patients recruited to a separate study evaluating the use of IDET (n=85). Patients were followed-up for 24 months. Oswestry Disability Index, visual analogue scale, quality of life (SF-36), radiographic evaluations, and NHS resource use. Cost-effectiveness was measured by the incremental cost per quality-adjusted life year (QALY) gained. Both treatments produced statistically significant improvements in pain, disability and quality of life at the 24-month follow-up. Costs were significantly lower with IDET due to a shorter mean procedure time (377.4 minutes vs. 49.9 minutes) and length of stay (7 days vs. 1.2 days). The mean incremental cost of IDET was -£3,713 per patient; the mean incremental QALY gain was 0.03. At a threshold of £20,000 per QALY the probability that IDET is cost-effective is 1, and the net health benefit is 0.21 QALY per patient treated. Both treatments led to significant improvements in patient outcomes which were sustained for at least 24 months. Costs were lower with IDET, and for appropriate patients IDET is an effective and cost-effective treatment alternative. Ethics approval: Ethics committee COREC. This cost-effectiveness analysis was carried out by the York Health Economics Consortium at the University of York, and was funded by Smith & Nephew. Smith & Nephew had no financial or other involvement in the collection or analysis of the data on which the CEA is based
