Tram-system related cycling injuries (TSRCI) most often occur when bicycle wheels catch in tram tracks, predominantly affecting young to middle-aged adults. These incidents frequently cause upper limb injuries, impact confidence, and lead to significant time off work and cycling.
Area of Science:
- Traumatology
- Public Health
- Biomechanics
Background:
- Tram-system related cycling injuries (TSRCI) are poorly understood.
- Existing literature lacks comprehensive data on injury patterns, patient demographics, and contributing factors.
- This study addresses the need for detailed insights into TSRCI to inform prevention and treatment strategies.
Purpose of the Study:
- To characterize the spectrum of injuries associated with tram-system related incidents.
- To identify demographic and socioeconomic factors of affected cyclists.
- To analyze accident circumstances, impact on cycling confidence, and consequences such as time off work and cycling.
Main Methods:
- Retrospective review of emergency service presentations for tram-related injuries in Edinburgh and West Lothian (May 2009 - April 2016).
- Analysis of medical records and imaging data.
- Telephone contact with patients for detailed questionnaires regarding accident circumstances and outcomes.
Main Results:
- 191 cyclists were identified, with fractures/dislocations in 63 cases, predominantly affecting the upper limb.
- Bicycle wheels caught in tram-tracks (142 cases) were the most common cause, with sliding on tracks more frequent in wet conditions.
- Traffic pressures were reported by 80 patients, and 120 experienced reduced cycling confidence, with 24 not resuming cycling. Fractures/dislocations correlated with longer recovery times.
Conclusions:
- TSRCI predominantly affect young to middle-aged adults with low socioeconomic deprivation, often due to wheels getting caught in tram-tracks.
- Injuries frequently involve the upper limb, and traffic pressures are common contributing factors.
- A significant proportion of cyclists experience diminished confidence and prolonged absence from work and cycling activities post-injury.
