Emerging Imaging Techniques in Anatomy: For Teaching, Research and Clinical Practice.

Visualisation plays a key role in anatomy, where the depiction of gross anatomical structures is essential in understanding and conceptualising content during research and medical teaching. Technology has allowed us to utilise imaging techniques for the visualisation of anatomical features, pathology and correlating physiological functions in a non-invasive manner which is atypical to traditional forms of anatomical investigation. These imaging methods develop integration between anatomy and clinically oriented medical study as well as biomechanics. The progressive research in anatomy can benefit from the vast field of biomechanics which allows for precise and conclusive results regarding the biomechanical integrity of anatomical structures and allows for intricate planning of procedures. 3D imaging techniques have enhanced the modelling of internal structures which are especially essential when implemented as diagnostic tools. An integration of these modalities into medical training accommodates for a more clinically orientated and immediate visualisation as produced when utilising ultrasound imaging which has the added advantage of 3D modelling and manipulation. Immersive technology has revolutionised teaching and learning particularly during the new age of hybrid education. Visualisation in anatomy has many clinical and educational applications which can optimise research, create interactive learning experiences and aid medical practise.

Sulci 3D mapping from human cranial endocasts: A powerful tool to study hominin brain evolution.

Key questions in paleoneurology concern the timing and emergence of derived cerebral features within the human lineage. Endocasts are replicas of the internal table of the bony braincase that are widely used in paleoneurology as a proxy for reconstructing a timeline for hominin brain evolution in the fossil record. The accurate identification of cerebral sulci imprints in endocasts is critical for assessing the topographic extension and structural organisation of cortical regions in fossil hominins. High-resolution imaging techniques combined with established methods based on population-specific brain atlases offer new opportunities for tracking detailed endocranial characteristics. This study provides the first documentation of sulcal pattern imprints from the superolateral surface of the cerebrum using a population-based atlas technique on extant human endocasts. Human crania from the Pretoria Bone Collection (South Africa) were scanned using micro-CT. Endocasts were virtually extracted, and sulci were automatically detected and manually labelled. A density map method was applied to project all the labels onto an averaged endocast to visualise the mean distribution of each identified sulcal imprint. This method allowed for the visualisation of inter-individual variation of sulcal imprints, for example, frontal lobe sulci, correlating with previous brain-MRI studies and for the first time the extensive overlapping of imprints in historically debated areas of the endocast (e.g. occipital lobe). In providing an innovative, non-invasive, observer-independent method to investigate human endocranial structural organisation, our analytical protocol introduces a promising perspective for future research in paleoneurology and for discussing critical hypotheses on the evolution of cognitive abilities among hominins.

Hello, can you hear me? Orthopaedic clinic telephone consultations in the COVID-19 era- a patient and clinician perspective.

BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic has resulted in seismic changes in healthcare delivery. As a result of this, hospital footfall required to be reduced due to increased risk of transmission of infection. To ensure patients can safely access healthcare, we introduced orthopaedic clinic telephone consultations in our busy district general hospital. AIM: To investigate patients' and clinicians' perspective of telephone consultations during COVID-19, and whether this method of consultation could be a viable option in the post- pandemic future. METHODS: This is a single centre, prospective study conducted in a busy National Health Service district general hospital. In May 2020, 100 non- consecutive adult patients were contacted by independent investigators within 48 h of their orthopaedic clinic telephone consultation to complete a telephone satisfaction questionnaire. The questions assessed satisfaction regarding various aspects of the consultation including overall satisfaction and willingness to use this approach long term. Satisfaction and perspective of 25 clinicians conducting these telephone consultations was also assessed via an online survey tool. RESULTS: 93% of patients were overall satisfied with telephone consultations and 79% were willing to continue this method of consultation post- pandemic. Patients found telephone consultations to reduce personal cost and inconvenience associated with attending a hospital appointment. 72% of clinicians reported overall satisfaction with this service and 80% agreed that telephone consultations should be used in the future. The majority found it less laborious in time and administration in comparison to face to face consultations. Patients and clinicians expressed their desire for video consultations as a method of further improving their experience with remote consultations. CONCLUSION: Our study has shown that telephone consultations are a safe and rapid method of adaptation to the COVID-19 pandemic, achieving the aim of reducing hospital footfall. This method of consultation has resulted in immense clinician and patient satisfaction. Our findings suggest that this tool has benefits in post pandemic healthcare delivery. It has also highlighted that telephone consultations can act as a steppingstone to the introduction of the more complex platform of video consulting.

Fractured Neck of Femur Management at a District General Hospital: Adherence to NICE guidelines CG124 for total hip replacement.

INTRODUCTION: The National Institute for Health and Care Excellence (NICE) in 2011 declared standards in the management of fracture neck of femur (NOF) patients suggesting a total hip replacement (THR) if necessary criteria were met. The Best Practice Tariff (BPT) states all NOF fracture patients should be operated on within 36 h of presentation to Accident & Emergency. We conducted this retrospective study for the years 2016-2018 to evaluate the adherence to these guidelines by Basildon and Thurrock University Hospital and compared the results with national standards. METHODS: Data for the period from 2016 to 2018 was collected from the National Hip Fracture Database (NHFD) retrospectively. The data was analysed to calculate various procedures performed for fracture NOF fixations, the number of THR's for displaced intracapsular fracture NOF, and percentage of patients operated within 36 h and evaluated reasons for the delay. RESULTS: Over the 3 years, the number of THR eligible displaced intracapsular neck of femur fracture patients that underwent THR was above the national average. Across all 3 years, the number of patients who underwent surgery within 36 h was less than the national average. Administrative/logistic reasons for the delay were the major cause for delayed surgery in all 3 years. CONCLUSION: Compliance with the NICE guidelines and achievement of national standards in NOF fracture care is achievable by most district general hospitals. Awareness and implementation of NICE guidelines for THRs need to be enhanced. A sustained, continual team effort and strict vigilance are necessary to prevent delayed surgery.

Infection in neuro-muscular scoliosis deformity correction.

Assess the outcome of a standardised protocol for the treatment of post-operative wound infection in patients undergoing deformity correction for neuro-muscular scoliosis (NMS). Retrospective review of 443 consecutive patients with a minimum 18 months' follow-up, following a primary posterior deformity correction for NMS. In patients who developed a wound complication, the patient demographic and comorbidities, causative pathogen, number of re-operations, length of stay (LOS), rate of cure, and complications were analysed. Forty-four patients (9.9%) developed a wound infection. Marginally more infections were mono-microbial (23) than poly-microbial (21). Coagulase negative staphylococcus and Staphylococcus aureus were the most commonly cultured pathogens. Seventeen patients were treated with antibiotics alone, while 27 patients also required surgical debridement. The average LOS for those treated with antibiotics alone was 12 days (range: 9-15 days), in contrast to those requiring debridement, which was 35 days (range: 35-70 days). All patients were cured from their infection and ultimately achieved fusion. Infection is common in NMS deformity correction. This is marginally more common as a mono-microbial than poly-microbial infection with most pathogens being staphylococcal in origin. Our defined treatment strategy resulted in a cure for all patients and capacity for all patients to achieve fusion.

Swellings of the sternoclavicular joint: review of traumatic and non-traumatic pathologies.

The sternoclavicular joint (SCJ) is an integral part of the shoulder girdle that connects the upper limb to the axial skeleton.Swelling of the SCJ is commonly due to trauma, degeneration, infections and other disease processes that affect synovial joints.This review also focuses on uncommon conditions that could affect the SCJ, including SAPHO (synovitis, acne, pustulosis, hyperostosis, osteitis) syndrome, Friedrich's disease and Tietze syndrome.The scope of this review is limited to the analysis of the current evidence on the various conditions affecting the SCJ and also to provide an algorithm to manage these conditions.

Arthroscopic knotless anterior labral stabilization using labral tape and wide awake anaesthesia-short term results.

BACKGROUND: The shoulder is the least constrained of all joints of the body and is more susceptible to injury including dislocation. The rate of recurrent instability following primary stabilization procedure at 10 years of follow-up ranged from 3.4 to 20%. There is a lack of evidence in the literature regarding use of labral tape and anchors for anterior stabilization despite the growing market for this product. We describe the outcomes of 67 patients who underwent knotless arthroscopic anterior stabilisation under awake anaesthesia using 1.5 mm LabralTape with 2.9 mm Pushlock anchors for primary anterior instability by a single surgeon. METHODS: This was a retrospective analysis of prospectively collected outcome data for adult patients undergoing anterior stabilisation for primary traumatic anterior shoulder instability between 2013 and 2016 at two centres. Patients with > 25% glenoid bone loss, engaging Hill Sach's, and multidirectional instability were excluded. All cases underwent surgery using awake anaesthetic technique. The surgical technique and post-operative physiotherapy was standardized. Outcomes were measured at 6 months and 12 months. RESULTS: Of the 74 patients in our study, 7 were lost to follow up. Outcomes were measured using the Oxford Instability Shoulder Score (OISS) and clinical assessment including the range of motion. The OISS showed statistically significant improvement from a mean score and standard deviation (SD) of 24.72 ± 2.8 pre-surgery to 43.09 ± 3.5 after the procedure at 12 months with good to excellent outcomes in 66 cases (98.5%). The mean abduction was 134.2 ± 6.32 and external rotation was 72.55 ± 5.42 at 60-90 position at 12 months. We report no failures due to knot slippage or anchor pull-out. CONCLUSION: Our case series using the above technique has distinct advantages of combining a small non-absorbable implant with flat, braided, and high-strength polyethylene tape. This technique demonstrates superior medium term results to conventional suture knot techniques for labral stabilization thereby validating its use.

Visualization Within the Ventricles of the Brain: A Micro-Focus X-Ray Study.

Conceptualization of the ventricular system of the brain by macroscopic studies is complicated by the lack of physical structure of these interconnected cavities. Dissection procedures designed to display the structures in the walls of the ventricles are destructive and not conducive for the appreciation of the ventricular system in its entirety. The application of Micro-focus X-ray tomography affords the possibility to appreciate hidden structures in a nondestructive manner. The aim of this study was to explore the possibility of using micro-focus X-ray tomography in the three-dimensional (3D) visualization of the ventricular system as well as the various neuroanatomical structures within its walls for educational purposes. Randomly selected embalmed human cadaver brains were scanned at Necsa (South African Nuclear Energy Corporation) housing the MIXRAD laboratory consisting of a Nikon XTH 225 ST micro-focus X-ray tomography facility. A 3D flythrough video of the ventricular system was reconstructed from these scans using software to view the inner surface of the ventricles. Micro-focus X-ray tomography provides feasible means of delivering high-resolution images in a nondestructive way to design a representation of the ventricular system. In addition, structures in the walls of the ventricular system could be appreciated in a novel way. It is envisaged that this 3D-fly-through video of the ventricular system will be valuable when integrated with standard prosections and atlas pictures in the educational setting. Further studies evaluating the use of this integrative visualization of the ventricular system of the brain for its applicability in the educational setting should be performed.

Barriers to staff reporting adverse incidents in NHS hospitals.

Our study assessed barriers to reporting adverse incidents (AIs). Adverse incident reporting (AIR), although it is a pillar of risk management, has a wide variation in staff perception and usage. A questionnaire was used in five NHS hospitals to assess 267 members of multidisciplinary team (MDT) staff usage of AIR. Thirty-three percent of staff had never reported an adverse incident (AI). Fourty-one percent of staff had missed opportunities to report AIs due to a poor response to previous reports. The group who missed opportunities had a significantly higher proportion of not having received feedback to their previous AI (p=0.03). In the group who had received training, 79% had submitted an AI. This was significantly higher than the group who had not received training (63%, p=0.02). Our study revealed that training and feedback following AIR are two major factors that could improve confidence in and use of AI reporting.
