Symptoms of AVN in the Foot and Ankle
A broken ankle or tibia may cause symptoms of avascular necrosis in the foot or ankle. The symptoms are typical of AVN, including pain, redness and swelling, but the ankle may also become unstable. Instability of the ankle may lead to an inability to walk on it.
Ankle movement is primarily flexion (bending the foot up) and extension (bending the foot down), both movements are essential for walking. Weight-bearing eventually becomes very painful, and the person may become disabled if not treated.
