Insights
Home confinement during COVID-19 significantly reduced pediatric fractures, particularly in boys. However, younger children, especially those under 4, still experienced fractures, indicating a need for continued vigilance.
Area of Science:
- Pediatric Orthopedics
- Epidemiology
- Public Health
Background:
- The COVID-19 pandemic necessitated widespread home confinement measures.
- Understanding the impact of these measures on pediatric injury patterns is crucial.
Purpose of the Study:
- To evaluate the effect of home confinement on the incidence and characteristics of pediatric fractures.
- To compare fracture data from the COVID-19 lockdown period with previous years.
Main Methods:
- Retrospective review of pediatric trauma admissions.
- Comparison of fracture data (etiology, location, demographics) from January-March 2020 versus 2017-2019.
- Statistical analysis to identify significant differences.
Main Results:
- A significant reduction in pediatric fractures was observed during the home confinement period in 2020.
- Traffic accident-related fractures decreased notably.
- The proportion of male children with fractures decreased, and the average age of affected children slightly lowered.
Conclusions:
- Home confinement effectively reduced overall pediatric fractures, especially those related to traffic accidents.
- A notable proportion of fractures still occurred in young children (under 4), with an increased representation of this age group.
- Continued attention to child safety during home isolation is warranted, particularly for younger age groups.
Objective:
To control the transmission of coronavirus disease 2019 (COVID-19), the Chinese government encouraged people to stay at home. This study aimed to evaluate the effects of home confinement on the occurrence of fractures among children.
Study Design:
We retrospectively reviewed children admitted to Children's Hospital of Chongqing Medical University, for traumatic injury from January 24 to March 10, 2020, and the same time period in 2017, 2018 and 2019. At the same time, children with fracture were screened out and the date for the past 4 years was compared in terms of etiology, location of fracture, sex and age to evaluate the effects of home confinement on the epidemiology of pediatric fractures during the COVID-19 outbreak.
Results:
There were 6066 fractures in5,346 patients in 2017-2019, and 1034 fractures in 862 patients in 2020; the number of patients in all years reached a peak at the age of 2 to 4 years. The patients were slightly younger in 2020 than in 2017-2019 (t = 9.953, 95% CI: 0.846-1.262), and the proportion of boys in 2017-2019 is higher than in 2020 (X2 = 6.944, P = 0.008). Home confinement and traffic restriction resulted in a reduction in traffic accidents-associated fractures among children (X2 = 16.399, P < 0.001).
Conclusion:
Home confinement lead to the significant reduction in the number of pediatric fractures, especially in male children, but the number of patients under 4 years old was still considerable, and the proportion of younger patients even increased. Therefore, the perspective of children should not be relaxed during home isolation.

Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...

Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
Flail Chest-I
Flail chest is a severe and potentially life-threatening condition characterized by the fracture of three or more adjacent ribs in multiple places. It is most commonly caused by direct impacts and trauma, such as motor vehicle accidents or injuries from a steering wheel impact. It can also occur due to falls in elderly individuals with osteoporosis, or assaults involving sharp objects.
Pathophysiology
The pathophysiology of flail chest is complex, involving fractures of...
