The effect of COVID-19 lockdowns on paediatric lower limb orthopaedic presentations

As the COVID-19 pandemic was spreading in 2020, the government imposed national lockdowns. We considered the effects these lockdowns had on the paediatric population, with a specific focus on lower limb orthopaedic trauma. We hypothesise that these restrictions will have altered the mechanisms of injury and reduced the number of referrals.

We retrospectively analysed data from 28/08/19 to 01/04/21, considering the variations in referrals and operations during these times, and analysed these data using an online statistical calculator. We examined the rate of referrals, types of fractures referred to the centre, mechanism of injury, volume of operations performed, and average wait times to undergo an operation. The data were compared in pre-lockdown and lockdown times.

67 paediatric patients with lower limb fractures were included in this study. Throughout the lockdown periods, the mean age of children referred was younger (6.9 from 11.1) and they were less likely to be injured as a result of sport (p = 0.0493). They were more likely to fracture their lower leg (p = 0.0016) when compared with other anatomical regions. The average weekly rate of referrals dropped (0.84-0.68), but the rate of operations almost quartered (0.39-0.16). The average wait times for operations dropped significantly, with patients waiting 80% less time from the date of their injury.

This study highlights the impact of the coronavirus pandemic on the prevalence and management of lower limb paediatric trauma. The demographics and mechanisms of injury which presented to the trust over the pandemic and associated national lockdowns were significantly different. There was a drop in the number of referrals and a preference to non-operative management when patients did present.
