Teens on Wheels and Consequences: A Six-Year Population-Based Study of Bicycle and Moped Injuries

On a collision course: fatal motorcycle and bicycle accidents of adolescents in Finland from 2008 to 2019

BACKGROUND

Transport injuries are a major cause of mortality among adolescents. Our aim was to evaluate the circumstances and trauma associated with fatal accidents involving adolescents and two-wheeled vehicles.

METHODS

We analyzed retrospective data from the Finnish Crash Data Institute from 2008 to 2019 involving 10- to 24-year-old victims of fatal traffic accidents who were injured while riding a bicycle, moped or motorcycle. We collected data on patient characteristics, accident circumstances and possible treatment. These fatalities were compared with national mortality rates among the respective age groups.

RESULTS

We identified 147 fatalities over the 12-year period involving 20 bicycle, 50 moped and 77 motorcycle riders. Most accidents involved males (n = 121, 82%). Less than half of vehicles were in good condition (46%); motorized vehicles were often illegally tuned (37%) or had tire problems (31%). Most of the accidents were collisions with another vehicle (n = 99, 67%) or other objects (n = 35, 24%). In 94% of cases, the Injury Severity Score was >25. Head injury was the most common cause of death (62%). Among 15-year-olds, every fifth death was due to accidents on two-wheeled vehicles.

CONCLUSIONS

Fatal transport accidents among adolescents comprise several elements that should be incorporated into driver's education and in case of minors, also communicated to parents. These include the condition of the vehicle, proper helmet use and effects of speed on both control of the vehicle and the consequences of a possible collision.

Incidence of femoral fractures in children and adolescents in Finland and Sweden between 1998 and 2016: A binational population-based study

BACKGROUND AND OBJECTIVE

Femoral fractures in children have significant impact for patients, family, and trauma resources as they usually require hospitalization and surgical treatment. The aim of this study was to determine the incidence and trends of femoral fractures among children and adolescents hospitalized between 1998 and 2016 in Finland and Sweden.

METHODS

All patients younger than 17 years of age in Finland and Sweden with a femoral fracture treated surgically between 1998 and 2016 were included in the study. Data were collected from National Hospital Discharge Registries. Patients were classified by gender and age into four groups. The annual incidences per 100,000 were calculated using annual mid-year population census data obtained from the Official Statistics of Finland and Sweden.

RESULTS

In total, 6410 patients younger than 17 years of age diagnosed with femoral fracture were included in this study. The total incidence per 100,000 femoral fractures was 13.3 in Finland and 11.0 in Sweden. The incidence of femoral fractures decreased during the study period in all age groups, except for teenage Finnish girls. Most of the fractures were located in femoral shaft. Fractures of the upper and distal femur were rare. Male predominance was detected in all age groups older than 1 year.

CONCLUSIONS

The incidence of femoral fractures decreased in all age groups except in teenage Finnish girls. Majority of femoral fractures were located in femoral shaft with male predominance. In children younger than 1 year of age, female predominance was found.
