Treatment and Prevention of Kohler's Disease
Kohler's Disease is a condition of the foot that affects the navicular bone. With this disease, the navicular bone develops avascular necrosis. Avascular necrosis can occur when the blood supply to the bones of the foot lessens or becomes constricted. If the bones are deprived of oxygenated blood, they can become brittle and die. The damage to the bone caused by blood depravation is often permanent. The result of Kohler's disease can be a collapse of the bone. This disease often occurs in children when the bone is temporarily deprived of oxygenated blood. This loss of blood supply is usually temporary, but the effect can often be permanent. The navicular bone is located at the heel of the foot.
What are the symptoms of Kohler's Disease?
When children first develop this rare disorder, they may often feel a tenderness in the rear of the foot or may have a pronounced limp when walking. Swelling and irritation will often occur in the area of the disorder. The disease is more common in males than females. The child usually starts experiencing symptoms around the age of 6. The affected individual will express discomfort in the feet on top of the apex of the longitudinal arch. He or she will walk with a limp. They will shift their weight to the other parts of the feet to compensate for the pain on the inside.
The exact cause of Kohler's disease is unknown. Some research has pointed to a strain around the navicular bone. Researchers point to difficulties in the navicular bone's development. The navicular bone may become compressed by other bones that have fully developed before it is fully grown. The child's added weight as a result of growing up may add additional pressures to the bone that has yet to ossify. Compression of the blood vessels carrying oxygen and other nutrients can cause ischemia. Ischemia will cause some of the symptoms of Kohler's Disease. When the condition corrects itself, the blood vessels will once again carry oxygenated blood to all the bones of the foot. The radial arrangement of blood vessels in the foot explains why the condition is able to correct itself.
What are some treatment options of Kohler's Disease?
- Weight loss for an obese son or daughter
- If the child has a very active lifestyle (running around all over the place) try to get them to ease up until the symptoms have subsided.
- Seek medical attention immediately. The condition will not get better on its own.
Medical treatment options may include a full cast for severe pain, a walking cast for moderate levels of pain, or some rest from rigorous physical activity. Non-steroidal anti-inflammatory medications may also reduce swelling in the affected areas.
