Overview
Metatarsal fractures, particularly those involving the base of the fifth metatarsal, are common foot injuries with an incidence of 6.7 per 100,000 persons annually, accounting for about 30% of metatarsal fractures 1.Diagnosis
Clinical Presentation: Pain, swelling, and tenderness localized to the base of the fifth metatarsal 1.
Imaging: Radiography is essential for diagnosis, often supplemented by MRI for complex fractures 1.
Classification: Fractures are categorized into zones I, II, and III based on location relative to anatomical landmarks 1.Management
Zone I Fractures:
- Functional Therapy: Early mobilization and weight-bearing activities recommended to hasten recovery 1.
- Immobilization: Alternative approach, though associated with longer recovery times 1.
Adjunctive Treatments:
- Pain Management: Nonsteroidal anti-inflammatory drugs (NSAIDs) for pain and inflammation 1.
- Rest and Ice: Initial management to reduce swelling and pain 1.Special Populations
Pediatrics: Specific management guidelines not detailed in provided abstracts 1.
Elderly: Considerations for slower healing and comorbidities not explicitly addressed 1.
Comorbidities: No specific recommendations for patients with comorbidities like diabetes or peripheral vascular disease 1.Key Recommendations
For Zone I fractures of the fifth metatarsal, functional therapy should be prioritized over immobilization to expedite return to work and full function (Evidence: Strong 1).
Radiographic imaging is crucial for accurate diagnosis and classification of metatarsal fractures (Evidence: Moderate 1).
Early use of NSAIDs can aid in managing pain and inflammation associated with metatarsal fractures (Evidence: Moderate 1).References
