Observational StudyImpact of societal restrictions and lockdown on trauma admissions during the COVID-19 pandemic: a single-centre cross-sectional observational study.
Societal restrictions and lockdown during the coronavirus (COVID-19) pandemic have had a significant impact on the volume and nature of trauma admissions. We assessed the impact of COVID-19 related societal restrictions and lockdown on trauma admissions to single level 1 trauma centre in Westmead, Australia. We hypothesized that the number of trauma admissions would decrease and number of admissions due to self-harm and assault (specifically domestic violence) would increase. ⋯ There was a significant decrease in the overall number of trauma-related admissions during the COVID-19-related period of societal restrictions and lockdown. This was due to a decrease in minor traumas, falls and road traffic collisions. There was no difference in the number of admissions secondary to major traumas, self-harm or assault.

ReviewTargeted muscle reinnervation to improve electromyography signals for advanced myoelectric prosthetic limbs: a series of seven patients.
Upper limb amputation is a devastating injury. Patients may choose to use a passive prosthesis, a traditional body-powered prosthesis or a myoelectric prosthesis driven by electromyography (EMG) signals generated by underlying muscles. Targeted muscle reinnervation (TMR) aims to surgically create strong and reliable signals to permit the intuitive use of a myoelectric prosthesis with the greatest number of movements possible. We review the Alfred Hospital experience of using TMR to improve upper limb prosthesis control. ⋯ The use of TMR to improve and increase the number of EMG signals has been successful in generating more degrees of freedom for upper limb amputees with myoelectric prostheses.
