Summary
Exercise bicycle hand injuries in children are often severe avulsions, frequently involving central digits. Awareness and equipment safety are crucial to prevent these preventable injuries.
Area of Science:
- Pediatric Orthopedics
- Trauma Surgery
- Biomedical Engineering
Background:
- Exercise bicycles pose a significant risk of hand injuries in children.
- Previous studies have not fully characterized the specific mechanisms and outcomes of these injuries.
Purpose of the Study:
- To analyze the incidence, mechanisms, injury types, and outcomes of hand injuries caused by exercise bicycles in children.
- To identify factors influencing injury severity and replantation success.
Main Methods:
- A 5-year retrospective review of 34 pediatric patients treated for exercise bicycle-related hand injuries.
- Data collected included patient demographics, injury mechanism, digit involvement, injury severity, and treatment outcomes.
Main Results:
- The mean age of affected children was 3 years and 5 months.
- Common injury mechanisms included chain/sprocket impingement (77%) and wheel spoke injuries (23%), with spoke injuries being more severe.
- Injuries ranged from lacerations (43%) to fractures (19%) and amputations (38%), predominantly affecting central digits (87%).
- Replantation was attempted in 33% of amputated digits, with a 50% survival rate.
Conclusions:
- Exercise bicycle hand injuries are often severe avulsions requiring careful consideration during replantation.
- There is a need for increased community awareness and improved equipment safety features to prevent these injuries.
