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

Aims. Scoliosis is a lateral curvature of the spine with associated rotation, often causing distress due to appearance. For some curves, there is good evidence to support the use of a spinal brace, worn for 20 to 24 hours a day to minimize the curve, making it as straight as possible during growth, preventing progression. Compliance can be poor due to appearance and comfort. A night-time brace, worn for eight to 12 hours, can achieve higher levels of curve correction while patients are supine, and could be preferable for patients, but evidence of efficacy is limited. This is the protocol for a randomized controlled trial of ‘full-time bracing’ versus ‘night-time bracing’ in adolescent idiopathic scoliosis (AIS). Methods. UK paediatric spine clinics will recruit 780 participants aged ten to 15 years-old with AIS, Risser stage 0, 1, or 2, and curve size (Cobb angle) 20° to 40° with apex at or below T7. Patients are randomly allocated 1:1, to either full-time or night-time bracing. A qualitative sub-study will explore communication and experiences of families in terms of bracing and research. Patient and Public Involvement & Engagement informed study design and will assist with aspects of trial delivery and dissemination. Discussion. The primary outcome is ‘treatment failure’ (Cobb angle progression to 50° or more before skeletal maturity); skeletal maturity is at Risser stage 4 in females and 5 in males, or ‘treatment success’ (Cobb angle less than 50° at skeletal maturity). The comparison is on a non-inferiority basis (non-inferiority margin 11%). Participants are followed up every six months while in brace, and at one and two years after skeletal maturity. Secondary outcomes include the Scoliosis Research Society 22 questionnaire and measures of quality of life, psychological effects of bracing, adherence, anxiety and depression, sleep, satisfaction, and educational attainment. All data will be collected through the British Spine Registry. Cite this article: Bone Jt Open 2023;4(11):873–880

Aims. The aim of this study was to identify factors associated with poor outcome following coccygectomy on patients with chronic coccydynia and instability of the coccyx. Methods. From the Danish National Spine Registry, DaneSpine, 134 consecutive patients were identified from a single centre who had coccygectomy from 2011 to 2019. Patient demographic data and patient-reported outcomes, including pain measured on a visual analogue scale (VAS), Oswestry Disability Index (ODI), EuroQol five-dimension five-level questionnaire, and 36-Item Short-Form Health Survey questionnaire (SF-36) were obtained at baseline and at one-year follow-up. Patient satisfaction was obtained at follow-up. Regression analysis, including age, sex, smoking status, BMI, duration of symptoms, work status, welfare payment, preoperative VAS, ODI, and SF-36 was performed to identify factors associated with dissatisfaction with results at one-year follow-up. Results. A minimum of one year follow-up was available in 112 patients (84%). Mean age was 41.9 years (15 to 78) and 97 of the patients were female (87%). Regression showed no statistically significant association between the investigated prognostic factors and a poor outcome following coccygectomy. The satisfied group showed a statistically significant improvement in patient-reported outcomes at one-year follow-up from baseline, whereas the dissatisfied group did not show a significant improvement. Conclusion. We did not identify factors associated with poor outcome following coccygectomy. This suggests that neither of the included parameters should be considered contraindications for coccygectomy in patients with chronic coccydynia and instability of the coccyx.

Aims. The aim of this study was to investigate the efficacy of coccygectomy in patients with persistent coccydynia and coccygeal instability. Methods. The Danish National Spine Registry, DaneSpine, was used to identify 134 consecutive patients who underwent surgery, performed by a single surgeon between 2011 and 2019. Routine demographic data, surgical variables, and patient-reported outcomes, including a visual analogue scale (VAS) (0 to 100) for pain, Oswestry Disability Index (ODI), EuroQol five-dimension questionnaire (EQ-5D), and the Physical Component Score (PCS) and Mental Component Score (MCS) of the 36-Item Short-Form Health Survey questionnaire (SF-36) were collected at baseline and one-year postoperatively. Results. A total of 112 (84%) patients with a minimum follow-up of one year had data available for analysis. Their mean age was 41.9 years, and 15 (13%) were males. At 12 months postoperatively, there were statistically significant improvements (p < 0.001) from baseline for the mean VAS for pain (70.99 to 35.34), EQ-5D (0.52 to 0.75), ODI (31.84 to 18.00), and SF-36 PCS (38.17 to 44.74). A total of 78 patients (70%) were satisfied with the outcome of treatment. Conclusion. Patients with persistent coccydynia and coccygeal instability resistant to nonoperative treatment may benefit from coccygectomy. Cite this article: Bone Joint J 2021;103-B(3):542–546

Background. Depression, anxiety, catastrophising, and fear-avoidance beliefs are some of the so-called “yellow flags” that predict a poor outcome in back patients. Many surgeons have difficulty assessing yellow flags, perhaps due to the complexity of existing instruments and time constraints during consultations. We developed a brief tool to allow the systematic evaluation of core flags. Methods. Data from 4 questionnaires (ZUNG depression (N=399); Hospital Anxiety and Depression Scale (Anxiety-subscale) (N=308); Pain Catastrophising (N=766); Fear Avoidance Beliefs (N=736)) were analysed to identify the respective single item that best represented the full scale score. The 4 items formed the “Core Yellow Flags Index” (CYFI). 1'768 patients completed CYFI and a Core Outcome Measures Index (COMI) preoperatively, and COMI 3 and 12mo later (FU). Results. The individual flag items correlated with their corresponding full-length questionnaires: 0.71 (depression), 0.81 (catastrophising), 0.77 (anxiety), 0.83 (fear avoidance beliefs). Cronbach's α for the 4 items was 0.79. Structural equation modelling revealed that CYFI explained a unique proportion of the variance in COMI at 3 months' FU (β=0.23, p< 0.001) and also at 12 months FU (β=0.20, p< 0.001). Conclusion. The 4-item CYFI proved to be a simple, practicable tool for routinely assessing key psychological attributes in spine surgery patients; it made a relevant contribution in predicting postoperative outcome. CYFI's items were similar to those in the “STarTBack screening-tool”, used in primary care to predict back pain chronicity, further substantiating its validity. Its wider use may help improve the accuracy of predictive models derived using spine registry data. No conflicts of interest. No funding obtained

Background. PROMs have become an integral assessment tool of clinical effectiveness and patient satisfaction. To date, PROMs for lumbar discectomy are not an NHS requirement, although voluntary collection via the British Spine Registry is encouraged. Despite this, PROMs for day case microdiscectomy is scarcely reported. We present PROMs for day case microdiscectomy at Lancashire Teaching Hospitals. Aims. 1). To review PROMs to quantify leg pain, back pain, EQ5D and ODI scores. 2). Evaluate PROMs data collection compliance. Methods. We studied PROMs data, taken prospectively as part of routine clinical care for all patients who underwent single level day case microdiscectomy between January 2013 to December 2015. PROMs included VAS for back and leg pain, EQ5D and ODI scores. Preoperative PROMs were compared to all available postoperative PROMs at 3 months, 6 months, 12 months and 24 months. Paired student T-tests were used to compare preoperative to postoperative scores. Results. Preoperative PROMs were recorded for 132 patients. Postoperative PROMs were recorded for 48 patients at 3 months, 51 patients at 6 months, 37 patients at 12 months and 15 patients at 24 months. Significant postoperative improvements (p<0.05) were found at all time points for back pain, leg pain, EQ5D and ODI, with the exception EQ5D at 24 months (p = 0.10). Conclusion. There was significant improvement in VAS back and leg scores, as well as ODI scores over 24 months. Further work is needed to improve compliance with postoperative PROMs and to optimise the benefit of these health assessment tools. No conflicts of interest. No funding obtained

Aims. Repeated lumbar spine surgery has been associated with inferior clinical outcomes. This study aimed to examine and quantify the impact of this association in a national clinical register cohort. Methods. This is a population-based study from the Norwegian Registry for Spine surgery (NORspine). We included 26,723 consecutive cases operated for lumbar spinal stenosis or lumbar disc herniation from January 2007 to December 2018. The primary outcome was the Oswestry Disability Index (ODI), presented as the proportions reaching a patient-acceptable symptom state (PASS; defined as an ODI raw score ≤ 22) and ODI raw and change scores at 12-month follow-up. Secondary outcomes were the Global Perceived Effect scale, the numerical rating scale for pain, the EuroQoL five-dimensions health questionnaire, occurrence of perioperative complications and wound infections, and working capability. Binary logistic regression analysis was conducted to examine how the number of previous operations influenced the odds of not reaching a PASS. Results. The proportion reaching a PASS decreased from 66.0% (95% confidence interval (CI) 65.4 to 66.7) in cases with no previous operation to 22.0% (95% CI 15.2 to 30.3) in cases with four or more previous operations (p < 0.001). The odds of not reaching a PASS were 2.1 (95% CI 1.9 to 2.2) in cases with one previous operation, 2.6 (95% CI 2.3 to 3.0) in cases with two, 4.4 (95% CI 3.4 to 5.5) in cases with three, and 6.9 (95% CI 4.5 to 10.5) in cases with four or more previous operations. The ODI raw and change scores and the secondary outcomes showed similar trends. Conclusion. We found a dose-response relationship between increasing number of previous operations and inferior outcomes among patients operated for degenerative conditions in the lumbar spine. This information should be considered in the shared decision-making process prior to elective spine surgery. Cite this article: Bone Joint J 2023;105-B(4):422–430

Aims

To identify the incidence and risk factors for five-year same-site recurrent disc herniation (sRDH) after primary single-level lumbar discectomy. Secondary outcome was the incidence and risk factors for five-year sRDH reoperation.

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. Methods. This was a comparative study using prospectively collected data from the Norwegian Registry for Spine Surgery. A total of 4,750 consecutive patients who underwent surgery for degenerative cervical radiculopathy and were followed for 12 months were included. Case-mix adjustment between those managed in public and private hospitals was performed using propensity score matching. The primary outcome measure was the change in the Neck Disability Index (NDI) between baseline and 12 months postoperatively. A mean difference in improvement of the NDI score between public and private hospitals of ≤ 15 points was considered equivalent. Secondary outcome measures were a numerical rating scale for neck and arm pain and the EuroQol five-dimension three-level health questionnaire. The duration of surgery, length of hospital stay, and complications were also recorded. Results. The mean improvement from baseline to 12 months postoperatively of patients who underwent surgery in public and private hospitals was equivalent, both in the unmatched cohort (mean NDI difference between groups 3.9 points (95% confidence interval (CI) 2.2 to 5.6); p < 0.001) and in the matched cohort (4.0 points (95% CI 2.3 to 5.7); p < 0.001). Secondary outcomes showed similar results. The duration of surgery and length of hospital stay were significantly longer in public hospitals. Those treated in private hospitals reported significantly fewer complications in the unmatched cohort, but not in the matched cohort. Conclusion. The clinical effectiveness of surgery for degenerative cervical radiculopathy performed in public and private hospitals was equivalent 12 months after surgery.

To prospectively determine the relationship between the two most commonly used generic spinal outcome measures, the Oswestry Disability Index (ODI) and the Low Back Outcome Score (LBOS). Outcome measures inform audit and research. Few spine surgical specific outcome measures are in general use. Generic measures are used for a variety of spinal disorders it is not known which is best or exactly how they relate for different conditions. Pre-operatively and two years post surgical results were available in 240 patients. There were 125 males, 115 females. Sub groups numbering 82 discetomy, 78 decompression, 26 revision and 19 fusions were analysed. Average age 55 years (range 23-88). The pre op average ODI was 55% and the LBOS was 29. Correlation was -0.73. The overall post operative score at 2 years was 34% ODI and 37 LBOS, the correlation was better at -0.87. The correlation between the two scores post operatively was very good for Discectomy surgery (-0.916) and fusion surgery (-0.907) but not so close pre operatively with Discectomy (-0.786) and fusion correlation poor at (-0.302). Revision surgery and decompression surgery had similar good correlation post operatively. The correlation of both outcome measures to the Modified Zung depression index was poor. The poor pre operative correlation suggests that thresholds for surgery cannot be compared within registries using different measures. The post operative scores and change in scores correlate better. This is important in comparative studies using different outcomes scores within the same spine registry. No conflict of Interest. Registered database and audit of service standard

Aims

The aim of the study was to determine if there was a direct correlation between the pain and disability experienced by patients and size of their disc prolapse, measured by the disc’s cross-sectional area on T2 axial MRI scans.

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.

Background. Previous surgery is known to increase the risk of complications during spine surgery, but few studies have quantified the dose-response effect using multivariate models to account for confounders. We quantified the effect of the number of prior spine surgeries on perioperative complications in patients undergoing surgery for lumbar degenerative disorders. Methods. We included data from 4′940 patients documented in Eurospine's Spine Tango Registry from 2004 to 2015. Medical history and surgical details were documented on the Tango Surgery form, as were surgical and general medical complications arising between admission and discharge. Multiple logistic regression models were built to investigate the relationship between the number of any previous surgeries and the presence of a perioperative complication, controlling for other potential confounders (age, sex, smoking, BMI, comorbidity, number of vertebral levels affected). Results. There were 9.4% surgical complications (most commonly dural tear, neurological sequelae, haematoma, infection) and 6.5 % general complications (most commonly cardiovascular, urinary, pulmonary, liver/GI). In the multivariable models, previous surgery significantly increased the odds of having a surgical complication (OR 1.148, 95%CI 1.051–1.253; p=0.002) and a medical complication (OR 1.185, 95%CI 1.074–1.307; p=0.001) i.e., for each previous surgery, the odds of a complication increased by 15% and 19%, respectively. Conclusion. We demonstrated a significant dose-response effect of previous surgery on the risk of incurring a complication during subsequent spine surgery. The results can be used by the surgeon when assessing the risk/benefit ratio of further surgery, for informing and consenting the patient. No conflicts of interest. No funding obtained

Aims

To report the outcome of spinal deformity correction through anterior spinal fusion in wheelchair-bound patients with myelomeningocele.

Aims

To report the surgical outcome of patients with severe Scheuermann’s kyphosis treated using a consistent technique and perioperative management.

Spinal stenosis and disc herniation are the two most frequent causes of lumbosacral nerve root compression. This can result in muscle weakness and present with or without pain. The difficulty when managing patients with these conditions is knowing when surgery is better than non-operative treatment: the evidence is controversial. Younger patients with a lesser degree of weakness for a shorter period of time have been shown to respond better to surgical treatment than older patients with greater weakness for longer. However, they also constitute a group that fares better without surgery. The main indication for surgical treatment in the management of patients with lumbosacral nerve root compression should be pain rather than weakness.

We investigated the pre-operative and one-year post-operative health-related quality of life (HRQoL) outcome by using a Euroqol (EQ-5D) questionnaire in 230 patients who underwent surgery for lumbar spinal stenosis. Data were obtained from the National Swedish Registry for operations on the lumbar spine between 2001 and 2002. We analysed the pre- and postoperative quality of life data, age, gender, smoking habits, pain and walking ability. The relative differences were compared to a Swedish EQ-5D population survey.

The mean age of the patients was 66 years, and there were 123 females (53%). Before the operation 62 (27%) of the patients could walk more than 500 m. One year after the operation 150 (65%) were able to walk 500 m or more.

The mean EQ-5D score improved from 0.36 to 0.64, and the HRQoL improved in 184 (80%) of the patients. However, they did not reach the level reported by a matched population sample (mean difference 0.18). Women had lower pre- and post-operative EQ-5D scores than men. Severe low back pain was a predictor for a poor outcome.
