Accessory Navicular
-
Kohler's Disease I:
- Anatomy:
- navicular joins in front w/ medial, intermediate, & lateral cuneiform bones, which articulate anteriorly
w/ first, second, and third metatarsals;
- navicular provides insertion for
tibialis posterior;
- blood supply to the navicular bone is radial and extraarticular & is subject to loss both at
time of injury & at time of surgical rx;
- Fracture:
-
navicular stress frx:
-
cortical avusion fractures:
-
body fractures;
-
longitudinal stress injuries of midtarsal joint:
- dorsal lip frx:
- look for assoc ankle sprain;
- w/ large lip frx or mid tarsal joint injury, then consider SLC;
- fracture dislocation:
- Assoc Injuries:
-
Midfoot/Forefoot Fractures:
-
Midtarsal Injuries:
Displaced intra-articular fractures of the tarsal navicular.
