Knowing the Causes of Accessory Bone of the Ankle
Accessory bones of the ankle are thought to be caused by abnormal development of the cartilage. This can happen due to genetic factors, trauma, or inflammation.
Accessory bones of the ankle are relatively common congenital anomalies that occur when the foot is developing in the womb. They are believed to develop due to an abnormal fusion of the cartilage that forms the tarsal bones.
They can range in size from very small to several centimeters in length and usually have no associated symptoms.
Understanding Accessory Bone of the Ankle Symptoms
- Pain
- Swelling
- Tenderness
- Difficulty walking
In some cases, there may be a visible bump on the ankle. Other symptoms may include stiffness of the ankle joint, difficulty bending the ankle, and a decrease in the range of motion in the ankle joint.
If left untreated, over time, the condition can cause progressive deterioration of the ankle joint, leading to further pain and disability. It can also result in arthritis and other degenerative joint diseases. It is important to seek medical attention if you suspect you may have an accessory bone of the ankle. At Foot & Ankle Centers of Frisco, Little Elm, & McKinney, we offer same-day appointments for urgent problems like fractures and sprained ankles.
Knowing how Accessory Bone of the Ankle is Diagnosed
