The UK government declared a national lockdown on 23 March 2020 to reduce transmission of COVID-19. This study aims to identify the effect of lockdown on the rates, types, mechanisms, and mortality of musculoskeletal trauma across Scotland. Data for all musculoskeletal trauma requiring operative treatment were collected prospectively from five key orthopaedic units across Scotland during lockdown (23 March 2020 to 28 May 2020). This was compared with data for the same timeframe in 2019 and 2018. Data collected included all cases requiring surgery, injury type, mechanism of injury, and inpatient mortality.Aims
Methods
Currently, there is no animal model in which
to evaluate the underlying physiological processes leading to the heterotopic
ossification (HO) which forms in most combat-related and blast wounds.
We sought to reproduce the ossification that forms under these circumstances
in a rat by emulating patterns of injury seen in patients with severe
injuries resulting from blasts. We investigated whether exposure
to blast overpressure increased the prevalence of HO after transfemoral
amputation performed within the zone of injury. We exposed rats
to a blast overpressure alone (BOP-CTL), crush injury and femoral
fracture followed by amputation through the zone of injury (AMP-CTL)
or a combination of these (BOP-AMP). The presence of HO was evaluated
using radiographs, micro-CT and histology. HO developed in none
of nine BOP-CTL, six of nine AMP-CTL, and in all 20 BOP-AMP rats.
Exposure to blast overpressure increased the prevalence of HO. This model may thus be used to elucidate cellular and molecular
pathways of HO, the effect of varying intensities of blast overpressure,
and to evaluate new means of prophylaxis and treatment of heterotopic
ossification. Cite this article:
