Navicular fractures
The navicular bone is found in front of the ankle joint and is prone to stress fractures over time and also acute injuries.
These are commonly seen in athletes, especially in distance runners. These fractures have tenuous bloody supply and can sometimes be difficult to heal. Surgery is typically recommended.
A bone graft is typically used in these fractures even in the primary setting because it can aid in healing.
Mr. Talia is always happy to see patients at short notice with foot and ankle injuries and if surgery is required this can typically be organised in a safe manner within recommended timeframes for the best outcome.

0-2 weeks: elevation at home, plaster cast or CAMboot
2-6 weeks: non weight bearing in CAMboot
6-10 weeks onwards: weight bearing in moon boot
>12 weeks: progress to strengthening

Risks of surgery
Swelling, stiffness
Infection and wound breakdown
Blood clots
Scar sensitivity, numbness in the foot
Ongoing pain
Progression to arthritis
Removal of implants
further surgery
A unique complication to navicular fractures is avascular necrosis where the bone dies off due to blood supply damage at the time of injury. this is closely monitored for with X-rays in the post operative period.
