Ankle and foot arthrodesis is done to relieve disabling ankle or foot pain, or deformity caused by poorly healed fractures, arthritis, damaged cartilage, infections, or developmental defects.
The procedure results in pain relief in most patients.
Complications are rare, but no procedure is completely free of risk. If you are planning to have an arthrodesis, your doctor will review a list of possible complications, which may include:
