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.

Centre Hospitalo-Universitaire de Lille, Service de Neurochirurgie et Chirurgie du Rachis, Lille, France. Assessment of current thoughts regarding spinal fellowships amongst spinal fellows in the United Kingdom and abroad. Qualitative analysis provides rich and contextual detail that cannot be borne out by quantitative research. We undertook detailed interviews amongst fellows who have varying fellowship experience both in the United Kingdom and abroad. Ten fellows, all of whom were approaching their Certificate of Completion of Training (or equivalent) in Trauma and Orthopaedic surgery, or just awarded the certificate. All undertaking/undertaken at least one 12-month fellowship. Qualitative experiences. A large unit provides a breadth of pathology that may is usually not encountered in smaller units. Fellows who worked in such units felt confident that they would recognise a variety of pathologies, but did not necessarily feel confident in their surgical management. Operative exposure to deformity surgery, whilst not necessarily a future part of practice, was felt useful for the added technical skills it provides. Fellows attending a smaller unit, where they may have been the sole ‘spinal fellow’, reported greater satisfaction in operative experience. Interestingly, there was felt to be a ‘saturation point’, where a fellow perceived no further educational benefit from remaining in one particular unit. A fellowship in spinal surgery is useful in preparing for independent practice as a spinal surgeon. Large units provide skills that are applicable to several aspects of spinal surgery. There appears to be a difference in breadth and complexity of pathology versus operative experience

Cochrane systematic review. The following databases were searched with no language limitations: the Cochrane Central Register of Controlled Trials, MEDLINE, EMBASE, CINHAL and reference lists of articles. Extensive hand searching of grey literature was also conducted. RCT's and prospective cohort studies comparing braces with no treatment, other treatment, surgery, and different types of braces were included. Two review authors independently assessed trial quality and extracted data. Two studies were included. There was very low quality evidence from one prospective cohort study including 286 girls. 1. indicating that braces curbed curve progression, at the end of growth, (success rate 74%), better than observation, (34%) and electrical stimulation (33%). Another low quality evidence from one RCT with 43 girls indicated that a rigid brace is more successful than an elastic one (SpineCor) at limiting curve progression when measured in Cobb degrees. 2. No significant differences between the two groups in the subjective perception of daily difficulties associated with brace wearing were found. There is very low quality evidence in favour of using braces, making generalization very difficult. The results from future studies may differ from these results. In the meantime, patients' choices should be informed by multidisciplinary discussion. Future research should focus on short and long-term patient-centred outcomes as well as measures such as Cobb angles. RCTs and prospective cohort studies should follow both the SRS and the Society on Scoliosis Orthopaedic and Rehabilitation Treatment (SOSORT) criteria for bracing studies

Introduction. Studies of the vestibular system in patients with idiopathic scoliosis (IS) have shown abnormalities in the semicircular canals (SCC) and the basicranium. Rousie (2008) revealed a statistically increased incidence of structural anomalies in the SCCs with three-dimensional computer generated modelling. Some of these findings were replicated in a small population by Cheng (2010). The primary goals of this investigation are verification of SCC abnormalities of patients with IS versus controls with use of three-dimensional modelling with subsequent development of a unique phenotypical classification. Our long-term goal is to provide new direction for hypothesis directed identification and characterisation of genes causally related to IS. Methods. 20 patients with IS and 20 controls matched for age and sex will be identified through the clinic with approval from the institutional review board. Power analyses were done to detect the difference in distributions as the proportion of fisher tests with p values less than 0·05. A sample size of 20 per group gives 86–99% power to realise results under conservative assumptions. IS patients and controls undergo vestibular system examination via T2 MRI imaging. Extracted data are evaluated by a team including Dr Rousie, ENT, radiology, and orthopaedic surgery. DNA is extracted with Gentra Puregene kits from Qiagen (Valencia, CA, USA). Developmental genes related to SCC and axial somatogenesis are being identified through a bioinformatics approach, targeting known IS genomic loci. Custom single-nucleotide polymorphism panels, statistical linkage, and association will identify genes of significance for sequencing. Results. To date, 11 patients with IS and four controls have been recruited. Preliminary data are indicative of a significant percentage of abnormalities within the SCC system in children with IS. Analyses of preliminary findings continue according to the protocol. Conclusions. Research into genetic factors predicting IS progression and/or magnitudes of curvature have been inconclusive. Whether these abnormalities are primary or secondary to a larger systemic issue is speculative; however, they demonstrate a potential new phenotypical classification. Our initial findings show evidence of SCC abnormalities in patients with IS in a well defined patient population compared with healthy controls. Ultimately, our goal for this project is to pursue investigations of genes, pseudogenes, and conserved sequences shown to be related to vestibular structural formation during embryogenesis and development. The identification of a subset of individuals with IS and vestibular abnormalities will allow for the study of genes involved concomitantly in the embryological development of both systems, thus providing insight into the inter-relationship of these deformities

Aims

Implant-related postoperative spondylodiscitis (IPOS) is a severe complication in spine surgery and is associated with high morbidity and mortality. With growing knowledge in the field of periprosthetic joint infection (PJI), equivalent investigations towards the management of implant-related infections of the spine are indispensable. To our knowledge, this study provides the largest description of cases of IPOS to date.

Aims

Magnetically controlled growing rods (MCGR) have been gaining popularity in the management of early-onset scoliosis (EOS) over the past decade. We present our experience with the first 44 MCGR consecutive cases treated at our institution.

Aims

Patients seeking cervical spine surgery are thought to be increasing in age, comorbidities and functional debilitation. The changing demographics of this population may significantly impact the outcomes of their care, specifically with regards to complications. In this study, our goals were to determine the rates of functionally dependent patients undergoing elective cervical spine procedures and to assess the effect of functional dependence on 30-day morbidity and mortality using a large, validated national cohort.

Aims

Our aim was to perform a systematic review of the literature to assess the incidence of post-operative epidural haematomas and wound infections after one-, or two-level, non-complex, lumbar surgery for degenerative disease in patients with, or without post-operative wound drainage.

Aims

In a multicentre, randomised study of adolescents undergoing posterior spinal fusion for idiopathic scoliosis, we investigated the effect of adding gelatine matrix with human thrombin to the standard surgical methods of controlling blood loss.

Wrong-level surgery is a unique pitfall in spinal surgery and is part of the wider field of wrong-site surgery. Wrong-site surgery affects both patients and surgeons and has received much media attention. We performed this systematic review to determine the incidence and prevalence of wrong-level procedures in spinal surgery and to identify effective prevention strategies. We retrieved 12 studies reporting the incidence or prevalence of wrong-site surgery and that provided information about prevention strategies. Of these, ten studies were performed on patients undergoing lumbar spine surgery and two on patients undergoing lumbar, thoracic or cervical spine procedures. A higher frequency of wrong-level surgery in lumbar procedures than in cervical procedures was found. Only one study assessed preventative strategies for wrong-site surgery, demonstrating that current site-verification protocols did not prevent about one-third of the cases. The current literature does not provide a definitive estimate of the occurrence of wrong-site spinal surgery, and there is no published evidence to support the effectiveness of site-verification protocols. Further prevention strategies need to be developed to reduce the risk of wrong-site surgery.

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.

We studied 70 consecutive patients with adolescent idiopathic scoliosis who underwent corrective surgery. They were divided into two groups. In the study group of 38 patients one or more modern blood-conservation measures was used peri-operatively. The 32 patients in the control group did not have these measures. Both groups were similar in regard to age, body-weight, the number of levels fused and the type of surgery.

Only two patients in the study group were transfused with homologous blood and these transfusions were ‘off-protocol’. Wastage of autologous pre-donated units was minimal (6 of 83 units). By contrast, all patients in the control group were transfused with homologous blood. In the study group there was a significant decrease (p = 0.005) in the estimated blood loss when all the blood-conservation methods were used.

The use of blood-conservation measures, the lowering of the haemoglobin trigger for transfusion and the education of the entire team involved in the care of the patient can prevent the need for homologous blood transfusion in patients undergoing surgery for adolescent idiopathic scoliosis.

We evaluated the use of surgical stabilisation for atlantoaxial subluxation after a follow-up of 24 years in 50 rheumatoid patients who had some degree of pain but no major neurological deficit.

The mortality of patients treated by atlantoaxial fusion was significantly lower than for those who received conservative treatment. The deaths resulted from infection or comorbid conditions. The significantly high relative risks of mortality from conservative treatment compared with surgical treatment were mutilating disease and susceptible factors on both of the HLA-DRB1 alleles. Relief from pain and neurological and functional recovery were better, and the radiological degree of atlantoaxial translocation was less in those who were surgically treated compared with those who were not. Two patients had superficial local infections after surgery. We conclude that prophylactic atlantoaxial fusion is better than conservative treatment in these patients.

In order to identify the risk factors and the incidence of post-operative spinal epidural haematoma, we analysed the records of 14 932 patients undergoing spinal surgery between 1984 and 2002. Of these, 32 (0.2%) required re-operation within one week of the initial procedure and had an International Classification of Diseases (ICD)-9 code for haematoma complicating a procedure (998.12). As controls, we selected those who had undergone a procedure of equal complexity by the same surgeon but who had not developed this complication. Risks identified before operation were older than 60 years of age, the use of pre-operative non-steroidal anti-inflammatories and Rh-positive blood type. Those during the procedure were involvement of more than five operative levels, a haemoglobin < 10 g/dL, and blood loss > 1 L, and after operation an international normalised ratio > 2.0 within the first 48 hours. All these were identified as significant (p < 0.03). Well-controlled anticoagulation and the use of drains were not associated with an increased risk of post-operative spinal epidural haematoma.
