Episode notes
High Risk of Navicular Stress Fractures
- Navicular stress fractures are high-risk due to avascular necrosis and often cause delayed or nonunion healing.
- Even elite athletes often respond well to initial non-operative treatment with cast immobilization and non-weight bearing for 6-8 weeks.
Navicular Bone Anatomy and Biomechanics
- The navicular bone articulates with cuneiforms, cuboid, calcaneus, and talus.
- It plays a key role in forefoot inversion and eversion biomechanics during motion.
Manage Navicular Stress Fractures Non-Operatively
- Treat navicular stress fractures with 6-8 weeks of cast immobilization and strict non-weight bearing.
- Operative treatment is reserved for non-union, failure of casting, or high-level athletes requiring faster recovery.
