Long-term consequences of PTW crashes: insights from European in-depth data

Area of Science:

• Road safety research
• Trauma and injury prevention
• Biomechanics of motorcycle accidents

Background:

• Powered-Two-Wheeler (PTW) riders are highly vulnerable in road traffic crashes.
• Crashes often lead to severe injuries and significant long-term health consequences.
• Understanding crash mechanisms is crucial for improving rider safety and quality of life.

Purpose of the Study:

• To investigate typical crash scenarios for PTW riders.
• To analyze injury patterns, influencing factors, and injury mechanisms.
• To identify factors contributing to long-term outcomes and reduced quality of life.

Main Methods:

• Analysis of 4,424 PTW crashes from three European databases (France, Germany, Great Britain).
• Inclusion of variables: collision type, speed, PTW model, protective gear, injury severity (AIS 2015), and predicted functional capacity index (pFCI).
• Focus on compiling a broad sample rather than country-specific comparisons.

Main Results:

• Frontal collisions at junctions were most frequent (57-67%), often involving a car turning across a PTW's path.
• Lower and upper extremities were most frequently injured; tibia, fibula, ulna, radius, and pelvic fractures frequently led to long-term consequences (pFCI ≤ 4).
• Injury causes included PTW handlebars, opponent vehicle structures, and the road; sport/conventional motorcycles and heavier PTWs were associated with higher injury severity.

Conclusions:

• PTW crashes, particularly frontal impacts at intersections, cause injuries with significant long-term consequences, mainly to extremities.
• Head injuries were less severe due to widespread helmet use.
• Injury mechanisms involve direct contact with vehicles and the road; PTW type influences severity, highlighting needs for improved prevention and care.
