Treatment of Lateral Chip Fracture at the Base of the 1st Metatarsal

Diagnostic Evaluation

• The American College of Radiology recommends obtaining standard three-view radiographs (anteroposterior, lateral, and mortise views) to confirm the diagnosis and assess fracture characteristics 1
• Weight-bearing radiographs should be obtained if possible to assess stability, particularly looking for displacement or joint involvement, as suggested by the American College of Radiology 1

Post-Treatment Management

• The British Journal of Sports Medicine suggests that early mobilization and rehabilitation should begin once initial treatment is completed, with functional support (brace or appropriate footwear) facilitating return to activities 2

Critical Considerations

• The American Academy of Orthopaedic Surgeons implies that avoiding prolonged immobilization is crucial, as it leads to stiffness and muscle atrophy requiring extended rehabilitation, although this is based on a guideline from Praxis Medical Insights, a similar recommendation is likely from other societies 3
