The impact of COVID-19 on the future of orthopaedic training in the UK.
We describe the effect COVID-19 has had at all levels of training in the UK within trauma and orthopaedics and evaluate how training might change in the future. We found that the COVID-19 pandemic has significantly impacted trainees within trauma and orthopaedics at all levels of training. It had led to reduced operative exposure, cancellations of examinations and courses, and modifications to speciality recruitment and annual appraisals. This cohort of trainees is witnessing novel methods of delivering orthopaedic services, which will continue to develop and become part of routine practice even once the pandemic has resol...

Does cup position differ between trabecular metal and titanium cups? A radiographic propensity score matched study of 300 hips.
addes M Abstract Background and purpose - The use of trabecular metal cups in primary total hip arthroplasty (THA) is increasing, despite the survival of Continuum cups being slightly inferior compared with other uncemented cups in registries. This difference is mainly explained by a higher rate of dislocation revisions. Cup malpositioning is a risk factor for dislocation and, being made of a highly porous material, Continuum cups might be more difficult to position. We evaluated whether Continuum cups had worse cup positioning compared with other uncemented cups.Patients and methods - Based on power calculation, ...

Physical child abuse demands increased awareness during health and socioeconomic crises like COVID-19.
ölfing JD Abstract Background and purpose - Physical abuse of children, i.e., nonaccidental injury (NAI) including abusive head trauma (AHT) is experienced by up to 20% of children; however, only 0.1% are diagnosed. Healthcare professionals issue less than 20% of all reports suspecting NAI to the responsible authorities. Insufficient knowledge concerning NAI may partly explain this low percentage. The risk of NAI is heightened during health and socioeconomic crises such as COVID-19 and thus demands increased awareness. This review provides an overview and educational material on NAI and its clinical presentat...
