Overview
Avulsion fracture of the anterior fibula occurs when the strong tendons attaching to the fibula are forcefully pulled, causing a small segment of bone to separate. This injury is common in sports involving sudden forceful movements, particularly in adolescents 1.Diagnosis
Clinical Presentation: Pain, swelling, and inability to bear weight on the affected leg 1.
Imaging: Radiography is typically sufficient for diagnosis, showing a fragment of bone separated from the main shaft 1.
Follow-Up Imaging: MRI or CT may be used to assess healing and rule out other conditions 1.Management
Initial Treatment: Immobilization with a splint or cast for 4-6 weeks to allow initial healing 1.
Rehabilitation: Gradual mobilization and strengthening exercises under physiotherapy guidance post-immobilization 1.
Pain Management: Nonsteroidal anti-inflammatory drugs (NSAIDs) for pain and inflammation control 1.Special Populations
Pediatrics: High incidence in adolescent athletes necessitates careful evaluation to differentiate from more serious conditions 1.
Training and Prevention: Review and modification of training programs and techniques to reduce injury risk in adolescent athletes 1.Key Recommendations
Early Radiological Assessment: Confirm diagnosis with imaging to differentiate from other conditions (Evidence: Moderate 1).
Immobilization Duration: Use immobilization for 4-6 weeks followed by structured rehabilitation (Evidence: Expert opinion 1).
Monitoring for Bilateral Injuries: Consider comprehensive evaluation in cases of bilateral injuries to rule out underlying pathologies (Evidence: Moderate 1).References
