However, significant gaps in the evaluation of these medical devices and applications hinder their regulatory evaluation. Addressing these gaps is critical to demonstrating the devices' safety and effectiveness.

Subtalar joint middle facet agenesis: a case report and literature review.

Articular facet morphology plays a fundamental role in subtalar joint biomechanics and stability, and likely influences the development of hindfoot osteoarthritis. While multiple anatomical studies have shown wide variation in articular facet configuration, the clinico-radiological findings are rarely presented. We illustrate a case of bilateral subtalar joint middle facet agenesis in a 45-year-old woman, which was missed despite several presentations.

Augmented reality simulator for CT-guided interventions.

Introduction: CT-guided interventions are taught using a mentored approach on real patients. It is well established that simulation is a valuable training tool in medicine. This project assessed the feasibility and acceptance of replicating a CT-guided intervention using a bespoke software application with an augmented reality head-mounted display (ARHMD).

Pictorial review of whole body MRI in myeloma: emphasis on diffusion-weighted imaging.

There have been major advances in myeloma imaging over the past few years with focal lesions on imaging now forming part of the disease defining criteria. Whole body diffusion-weighted MRI (WB-MRI) is considered the most sensitive technique for the detection of focal active lesions. This pictorial review will focus on imaging the spectrum of myelomatous disorders on WB-MRI including diffusion and Dixon sequences.

Remote reporting in the COVID-19 era: from pilot study to practice.

Aim: To assess the benefits and challenges of remote reporting using an intra-departmental teleradiology system.

Materials And Methods: A pilot of an in-hospital Trust radiologist reporting on in-hospital Trust patients via a remote login was undertaken. Reporting output, training impact, and quality improvement were measured.

Ultrasound-guided muscle biopsy: a practical alternative for investigation of myopathy.

Objective: We propose the use of ultrasound-guided muscle biopsy as a viable method of obtaining muscle specimen to aid the diagnosis of myopathy. We retrospectively review the diagnostic accuracy and patient feedback of ultrasound-guided muscle biopsies in our neuromuscular service.

Method: Multidisciplinary team meeting reviewed select patients and agreed on those suitable for ultrasound-guided muscle biopsy.

Missed posterior shoulder fracture dislocations: a new protocol from a London major trauma centre.

Background: A high incidence of missed posterior shoulder dislocations is widely recognised in the literature. Concern was raised by the upper limb multidisciplinary team at a London major trauma centre that these missed injuries were causing serious consequences due to the need for surgical intervention and poor functional outcome.

Objective: To identify factors contributing to missed diagnosis and propose solutions.

Assessment of the young adult hip joint using plain radiographs.

Radiographic examination remains the mainstay of the initial assessment of the young adult hip; however, common parameters are required to assist in the formation of accurate diagnoses and appropriate management plans. This paper aims to summarise the most important aspects of the assessment of plain radiographs performed on the young adult hip joint.

Imaging in myeloma with focus on advanced imaging techniques.

In recent years, there have been major advances in the imaging of myeloma with whole body MRI incorporating diffusion-weighted imaging, emerging as the most sensitive modality. Imaging is now a key component in the work-up of patients with a suspected diagnosis of myeloma. The International Myeloma Working Group now specifies that more than one focal lesion on MRI or lytic lesion on whole body low-dose CT or fludeoxyglucose (FDG) PET/CT fulfil the criteria for bone damage requiring therapy.

Changes in northern hemisphere male international rugby union players' body mass and height between 1955 and 2015.

Objectives: We sought to establish the effects of professionalism, which officially began in 1995, on the body mass and height of northern hemisphere male international rugby union (RU) players. We hypothesised that mass would significantly increase following professionalism. We also investigated the changes in size of players according to their playing position, and we compared changes to rugby league (RL) players and the public.

Through the HoloLens™ looking glass: augmented reality for extremity reconstruction surgery using 3D vascular models with perforating vessels.

Precision and planning are key to reconstructive surgery. Augmented reality (AR) can bring the information within preoperative computed tomography angiography (CTA) imaging to life, allowing the surgeon to 'see through' the patient's skin and appreciate the underlying anatomy without making a single incision. This work has demonstrated that AR can assist the accurate identification, dissection and execution of vascular pedunculated flaps during reconstructive surgery.

A 23-year-old amateur football player presented 9 months after acute onset of severe pain and a lump in the posterior right knee whilst lifting a heavy box. He had been unable to return to playing football or climbing the stairs. Clinically, a Baker's cyst was suspected.

Ring Ring Ring! Characterising Telephone Interruptions During Radiology Reporting and How to Reduce These.

Background: Telephone calls remain one of the most frequent interruptions in radiology reporting rooms, despite modern electronic order communication systems. A call received by a radiology trainee during the hour before completing a report may increase the chance of a discrepancy by 12%.

Aim: To characterise telephone calls to radiology reporting rooms and identify ways to reduce these interruptions.

Autoimmune necrotising myopathy and HMGCR antibodies.

Statins lower serum cholesterol concentrations by inhibiting the enzyme 3-hydroxy-3-methylglutaryl-coenzyme A reductase (HMGCR). Muscle side effects are relatively common and include asymptomatic elevation of serum creatine kinase (CK), myalgia, proximal muscle weakness and rhabdomyolysis. More recently, a subset of cases of immune-mediated necrotising myopathy has been found to have antibodies against HMGCR.

Physes around the shoulder girdle: normal development and injury patterns.

Traumatic injuries involving the scapula and clavicle in skeletally immature patients have unique characteristics that distinguish them from similar injuries in the mature skeleton. Fractures involving unossified cartilage and unfused epiphyses are difficult to appreciate on plain radiographs and computed tomography (CT) imaging. Knowledge of the developmental anatomy and normal radiological appearances during different stages of development of these bones is an essential prerequisite for the radiologist tasked with interpreting the imaging of such injuries in order to avoid potential diagnostic pitfalls.
