Summary
This study examines two severe pronation-eversion ankle fractures sustained during sports. Despite the fracture severity, medial ankle structures remained intact, suggesting a complex injury mechanism.
Area of Science:
- Orthopedic Surgery
- Sports Medicine
- Biomechanics
Background:
- Pronation-eversion fractures are severe ankle injuries often associated with sports.
- Understanding the precise trauma mechanism is crucial for effective treatment and prevention.
Observation:
- Two cases of grade four pronation-eversion ankle fractures sustained during athletic activities are presented.
- In both cases, the medial structures of the ankle joint were found to be intact post-injury.
Findings:
- The exact trauma mechanism for these specific fractures remains unclear.
- A potential explanation involves the ankle and subtalar joints acting as a torsion transmitter, as proposed by Inman (1976).
Implications:
- This case series highlights the complexity of severe ankle fractures in athletes.
- Further biomechanical research may be needed to fully elucidate the mechanisms behind these injuries.
- Consideration of the ankle as a torsion transmitter could inform future injury prevention strategies in sports.
