This study examined spinal fractures in patients admitted to a Major Trauma Centre via two independent pathways, a major trauma (MT) pathway and a standard unscheduled non-major trauma (NMT) pathway. A total of 134 patients were admitted with a spinal fracture over a period of two years; 50% of patients were MT and the remainder NMT. MT patients were predominantly male, had a mean age of 48.8 years (13 to 95), commonly underwent surgery (62.7%), characteristically had fractures in the cervico-thoracic and thoracic regions and 50% had fractures of more than one vertebrae, which were radiologically unstable in 70%. By contrast, NMT patients showed an equal gender distribution, were older (mean 58.1 years; 12 to 94), required fewer operations (56.7%), characteristically had fractures in the lumbar region and had fewer multiple and unstable fractures. This level of complexity was reflected in the length of stay in hospital; MT patients receiving surgery were in hospital for a mean of three to four days longer than NMT patients. These results show that MT patients differ from their NMT counterparts and have an increasing complexity of spinal injury. Cite this article: Bone Joint J 2015;97-B:235–9

Aims. The purpose of this retrospective study was to investigate the clinical relevance of increased facet joint distraction as a result of anterior cervical decompression and fusion (ACDF) for trauma. Patients and Methods. A total of 155 patients (130 men, 25 women. Mean age 42.7 years; 16 to 87) who had undergone ACDF between 1 January 2001 and 1 January 2016 were included in the study. Outcome measures included the Neck Disability Index (NDI) and visual analogue scale (VAS) for pain. Lateral cervical spine radiographs taken in the immediate postoperative period were reviewed to compare the interfacet distance of the operated segment with those of the facet joints above and below. Results. There was a statistically significant relationship between greater facet distraction and increased NDI and VAS pain scores. This was further confirmed by Spearman correlation, which showed evidence of a moderate correlation between both NDI score and facet joint distraction (Spearman correlation coefficient 0.34; p < 0.001) and VAS score and facet distraction (Spearman correlation coefficient 0.52; p < 0.001). Furthermore, there was a discernible transition point between outcome scores. Significantly worse outcomes, in terms of both NDI scores (17.8 vs 8.2; p < 0.001) and VAS scores (4.5 vs 1.3; p < 0.001), were seen with facet distraction of 3 mm or more. Patients who went on to have a posterior fusion also had increased NDI and VAS scores, independent of facet distraction. Conclusion. After undergoing ACDF for the treatment of cervical spine injury, patients with facet joint distraction of 3 mm or more have worse NDI and VAS pain scores.

Background. Thoracolumbar fractures are the most common spinal injuries resulting from blunt trauma. Missed spinal injuries can have serious consequences. Objective. Our objectives were to determine the utility of trauma series chest and abdomen computed tomographs for detecting clinically unrecognised vertebral fractures and to analyse those missed on clinical examination. The aim was to identify an ‘at-risk’ patient group with negative clinical examination warranting evaluation with CT screening. Material and Methods. We evaluated all computed tomography of the chest and/or abdominal that was undertaken for blunt trauma at our trauma centre from April 2009 to April 2010. Data was gathered from both CT scans and medical notes to capture demographics, mechanism of injury, fracture site and configuration. Key points were the clinical suspicion of vertebral fractures prior to CT request and identifying ‘at-risk’ patient group with factors contributing to difficulty in clinical interpretation. Results. There were a total of 303 patients in the year who underwent CT scan for blunt trauma. 51(16.8%) had a thoracolumbar vertebral fracture. There were 8 women and 43 men a mean age of 45.2 years. There were 29 (56.8%) stable and 22 (43.2%) unstable fractures. Out of the 51 total fracture patients, only 17(33.3%) had been clinically anticipated with a positive clinical examination. In the 22 unstable fractures, only 11 (50%) were expected and had clinically recorded correlating positive examination findings. Conclusion. A combination of both clinical examination and CT screening based on mechanism will likely be required to ensure adequate sensitivity with an acceptable specificity for the diagnosis of clinically significant injuries of the TL spine

Aims. The timing of surgical fixation in spinal fractures is a contentious topic. Existing literature suggests that early stabilization leads to reduced morbidity, improved neurological outcomes, and shorter hospital stay. However, the quality of evidence is low and equivocal with regard to the safety of early fixation in the severely injured patient. This paper compares complication profiles between spinal fractures treated with early fixation and those treated with late fixation. Methods. All patients transferred to a national tertiary spinal referral centre for primary surgical fixation of unstable spinal injuries without preoperative neurological deficit between 1 July 2016 and 20 October 2017 were eligible for inclusion. Data were collected retrospectively. Patients were divided into early and late cohorts based on timing from initial trauma to first spinal operation. Early fixation was defined as within 72 hours, and late fixation beyond 72 hours. Results. In total, 86 patients underwent spinal surgery in this period. Age ranged from 16 to 88 years. Mean Injury Severity Score (ISS) was higher in the early stabilization cohort (p = 0.020). Age was the sole significant independent variable in predicting morbidity on multiple regression analysis (p < 0.003). There was no significant difference in complication rates based on timing of surgical stabilization (p = 0.398) or ISS (p = 0.482). Conclusion. Our results suggest that these patients are suitable for early appropriate care with spinal precautions and delayed definitive surgical stabilization. Earlier surgery conferred no morbidity benefit and had no impact on length of stay. Cite this article: Bone Joint J 2020;102-B(5):627–631

Aims

Traumatic central cord syndrome (CCS) typically follows a hyperextension injury and results in motor impairment affecting the upper limbs more than the lower, with occasional sensory impairment and urinary retention. Current evidence on mortality and long-term outcomes is limited. The primary aim of this study was to assess the five-year mortality of CCS, and to determine any difference in mortality between management groups or age.

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. Serious traumatic injury is a leading cause of death and disability globally, with the majority of survivors developing chronic pain. Methods. 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. Results. 124 eligible participants were recruited. At 6-months, 19 (23.2%) of 82 respondents reported a good outcome, whereas at 12-months 27 (61.4%) of 44 respondents reported a good outcome. The multivariate model for 6-months produced odds ratios for a unit increase in: number of fractures, 3.179 (0.52 to 19.61); average pain intensity, 1.611 (0.96 to 2.7); pain extent, 1.138 (0.92 to 1.41) and post-traumatic stress symptoms, 1.044 (0.10 to 1.10). At 12-months, equivalent values were: number of fractures, 1.653 (0.77 to 3.55); average pain intensity, 0.967 (0.67 to 1.40); pain extent, 1.062 (0.92 to 1.23) and post-traumatic stress symptoms, 1.025 (0.99 to 1.07). Conclusion. A poor long-term pain outcome from musculoskeletal traumatic injuries can be predicted by measures recorded within days of injury. Conflicts of interest: No conflicts of interest.

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 (795.6mm. 2. vs. 906.5mm. 2. , p<0.01), but it was not significantly different in follow-up MRI (795.6mm. 2. vs. 814.4mm. 2. , p=1.00). However, in case of IELD, the ipsilateral CSAs in preoperative, postoperative, and follow-up periods were 892.0 mm. 2. , 909.3 mm. 2. , and 900.3 mm. 2. , 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

Introduction. 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. Methods. 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. Results. A total of 1182 patients had a Whole-Body SPECT CT used for the spinal analysis. After exclusions (age >80 [n=260], non-cancer [n=318], back pain [n=72]), 522 reports with cancer were utilised. Mean age was 65 (4–80). Age and distribution of DS are given in the table. Conclusion. The prevalence of radiological asymptomatic DS is prevalent in large proportions of patients without back pain, and its incidence increases with age. Approximately 60% of 60 year old and 70% of 70 years old patients have asymptomatic DS in the lumbosarcal region. We conclude that SPECT/CT will detect radiographic degenerative spondylosis in an asymptomatic hospital cohort and this prevalence increase with age. Therefore, this modality of imaging must be utilised with caution when investigating potential pain generators. For any figures or tables, please contact the authors directly

Introduction. 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. Methods and Materials. 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. Results. 404 (n) spinal surgeries were performed over this two-year period. Surgical demographics: 39.4% (159/404) males and 56.2% (227/404) females, 4.5% (18/404) declined to be added. Age ranging from 6 to 92, mean age was 47.9. Staff compliance was 89.4% for the registration of patient data. Trauma and tumour patients were excluded as they are not required to complete any pre-operative PROMs. For the remaining patients, 35.8% (116/324) completed their baseline pre-operative PROMs. A steady decrease in patient compliance for post-operative PROMS was observed: 29.8% (2 weeks), 24.9% (6 weeks), 21.2% (6 months), 17.1% (12 months), and 16.6% (24 months). Conclusions. We identified a poor patient compliance in both pre-operative and post-operative PROMS. Patient questionnaire fatigue can occur over time which results in falling compliance to PROMS in 12 months and 24 months. Moreover, patients who do not provide an email address are less likely to fill in their PROMS. Satisfactory compliance for staff regarding to BSR utilisation are shown. Staff should aim to achieve a higher level of compliance as this will help to keep a record of all spinal surgeries that are performed and any complications that are encountered in a particular centre. Over the past three years, the BSR had introduced various schemes to drive up utilisation including a Best Practice Tariff in 2019. Part of the tariff will be withheld when staff failure to enter patients onto the Registry. Further research is needed to determine why there is such fall off especially with patient compliance and to elucidate potential measures to improve their compliance

Aims. The aim of this study was to identify the risk factors for adverse events following the surgical correction of cervical spinal deformities in adults. Methods. We identified adult patients who underwent corrective cervical spinal surgery between 1 January 2007 and 31 December 2015 from the MarketScan database. The baseline comorbidities and characteristics of the operation were recorded. Adverse events were defined as the development of a complication, an unanticipated deleterious postoperative event, or further surgery. Patients aged < 18 years and those with a previous history of tumour or trauma were excluded from the study. Results. A total of 13,549 adults in the database underwent primary corrective surgery for a cervical spinal deformity during the study period. A total of 3,785 (27.9%) had a complication within 90 days of the procedure, and 3,893 (28.7%) required further surgery within two years. In multivariate analysis, male sex (odds ratio (OR) 0.90 (95% confidence interval (CI) 0.8 to 0.9); p = 0.019) and a posterior approach (compared with a combined surgical approach, OR 0.66 (95% CI 0.5 to 0.8); p < 0.001) significantly decreased the risk of complications. Osteoporosis (OR 1.41 (95% CI 1.3 to 1.6); p < 0.001), dyspnoea (OR 1.48 (95% CI 1.3 to 1.6); p < 0.001), cerebrovascular accident (OR 1.81 (95% CI 1.6 to 2.0); p < 0.001), a posterior approach (compared with an anterior approach, OR 1.23 (95% CI 1.1 to 1.4); p < 0.001), and the use of bone morphogenic protein (BMP) (OR 1.22 (95% CI 1.1 to 1.4); p = 0.003) significantly increased the risks of 90-day complications. In multivariate regression analysis, preoperative dyspnoea (OR 1.50 (95% CI 1.3 to 1.7); p < 0.001), a posterior approach (compared with an anterior approach, OR 2.80 (95% CI 2.4 to 3.2; p < 0.001), and postoperative dysphagia (OR 2.50 (95% CI 1.8 to 3.4); p < 0.001) were associated with a significantly increased risk of further surgery two years postoperatively. A posterior approach (compared with a combined approach, OR 0.32 (95% CI 0.3 to 0.4); p < 0.001), the use of BMP (OR 0.48 (95% CI 0.4 to 0.5); p < 0.001) were associated with a significantly decreased risk of further surgery at this time. Conclusion. The surgical approach and intraoperative use of BMP strongly influence the risk of further surgery, whereas the comorbidity burden and the characteristics of the operation influence the rates of early complications in adult patients undergoing corrective cervical spinal surgery. These data may aid surgeons in patient selection and surgical planning. Cite this article: Bone Joint J 2021;103-B(4):734–738

Aims

Patients with cauda equina syndrome (CES) require emergency imaging and surgical decompression. The severity and type of symptoms may influence the timing of imaging and surgery, and help predict the patient’s prognosis. Categories of CES attempt to group patients for management and prognostication purposes. We aimed in this study to assess the inter-rater reliability of dividing patients with CES into categories to assess whether they can be reliably applied in clinical practice and in research.

Aims

The aim of this study was to investigate whether the type of cervical disc herniation influences the severity of symptoms at the time of presentation, and the outcome after surgical treatment.

Aims

This systematic review aims to identify 3D predictors derived from biplanar reconstruction, and to describe current methods for improving curve prediction in patients with mild adolescent idiopathic scoliosis.

Aims

The optimal procedure for the treatment of ossification of the posterior longitudinal ligament (OPLL) remains controversial. The aim of this study was to compare the outcome of anterior cervical ossified posterior longitudinal ligament en bloc resection (ACOE) with posterior laminectomy and fusion with bone graft and internal fixation (PTLF) for the surgical management of patients with this condition.

Aims

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

Aims

This study aimed, through bioinformatics analysis and in vitro experiment validation, to identify the key extracellular proteins of intervertebral disc degeneration (IDD).

Aim. Identifying cervical spine injuries in confused or comatose patients with multiple injuries provides a diagnostic challenge. Our aim was to investigate the protocols which are used for the clearance of the cervical spine in these patients in English hospitals. Patients and Methods. All hospitals in England with an Emergency Department were asked about the protocols which they use for assessing the cervical spine. All 22 Major Trauma Centres (MTCs) and 141 of 156 non-MTCs responded (response rate 91.5%). Results. Written guidelines were used in 138 hospitals (85%). CT scanning was the first-line investigation in 122 (75%). A normal CT scan was sufficient to clear the cervical spine in 73 (45%). However, 40 (25%) would continue precautions until the patient regained full consciousness. MRI was performed in all confused or comatose patients with a possible cervical spinal injury in 15 (9%). There were variations in the grade and speciality of the clinician who had responsibility for deciding when to discontinue precautions. A total of 31 (19%) reported at least one missed cervical spinal injury following discontinuation of spinal precautions within the last five years. Only 93 (57%) had a formal mechanism for reviewing missed injuries. Take home message: There are significant variations in protocols and practices for the clearance of the cervical spine in multiply injured patients in acute hospitals in England. The establishment of trauma networks should be taken as an opportunity to further standardise trauma care. Cite this article: Bone Joint J 2016;98-B:825–8

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.

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.
