Navicular Stress Fracture
The navicular bone is on top of the heel bone, and a navicular stress fracture is commonly seen in athletes that are involved in sprinting, jumping or hurdling. Sports and activities that require excessive amounts of sudden changes in direction or explosive moments put abnormal pressure on the bone and can cause a stress fracture over time.
Patients usually experience a general ache in the mid-foot just beyond the ankle. The pain increases after activity and dissipates with rest. There may be a small degree of swelling in this area and the fracture can be seen on a bone scan.
This type of fracture calls for a short-leg cast to be worn over six weeks and total immobility of the foot during that time. In some patients, a cast is not sufficient and surgery may be required.
