Treatment of Nondisplaced Fifth Metatarsal Base Fracture
Diagnosis
- Initial evaluation should include three standard radiographic views (anteroposterior, lateral, and mortise) that include the base of the fifth metatarsal bone, as recommended by the American College of Radiology 1, 2
- Weight-bearing radiographs, if possible, provide important information about fracture stability, according to the American College of Radiology 1
- The Ottawa Ankle Rules should be applied to determine the need for radiographs in patients with ankle trauma, as suggested by the American College of Radiology and the British Journal of Sports Medicine 1, 3
Treatment Algorithm for Nondisplaced Fifth Metatarsal Base Fractures
Conservative Management
- Regular radiographic assessment to ensure proper healing and alignment is necessary, as recommended by Praxis Medical Insights 4
- Progressive weight-bearing as tolerated after initial immobilization period is advised, according to Praxis Medical Insights 4
Rehabilitation Protocol
- Early introduction of physical training and muscle strengthening followed by balance training after immobilization period is recommended, as suggested by Praxis Medical Insights 4
- Avoid prolonged immobilization to prevent stiffness and muscle atrophy, as advised by Praxis Medical Insights 4
Common Pitfalls to Avoid
- Failing to include the base of the fifth metatarsal in ankle radiographs should be avoided, as recommended by the American College of Radiology 1, 2
- Unnecessary ordering of foot radiographs when ankle radiographs already include the fifth metatarsal base should be avoided, according to the American College of Radiology 1
