Symptoms of Kohler’s Disease

Kohler’s Disease is a condition that affects the Navicular Bone, which is located on the medial arch of the foot. It occurs in children, commonly between the ages of 4-7, but can be found in children as young as 2.

Kohler’s Disease is more common in boys than girls, but it can occur at a younger age in girls. Patients often report pain in the inner aspect of their foot, they may limp when walking, and there is often visible swelling on the foot. There is pain on palpation of the medial arch of the foot, and running or hopping often worsens the pain.

Kohler’s Disease Causes

The exact cause of Kohler’s Disease is unknown, but we know that it is a result of decreased blood flow to the Navicular bone resulting in avascular necrosis of the bone.

The navicular bone is the last tarsal bone to ossify, and while the aetiology of Kohler’s Disease is not fully understood, it is thought to be caused by the compression of the navicular bone by the surrounding ossified Talus and Cuneiform bones.

Diagnosis of Kohler’s Disease

A consultation with a Musculoskeletal Physician or a Paediatric Physical Therapist is recommended if you are suspicious of having Kohler’s Disease. A clinical examination can identify the location of pain, and it should be complemented with an x-ray to achieve a clinical diagnosis.

On plain films, the navicular will have standard avascular necrosis (AVN) characteristics, including sclerosis, fragmentation, and flattening.

Kohler’s Disease: Treatment

A Paediatric Physical Therapist is in an excellent position to offer appropriate treatment for Kohler’s Disease. In severe cases, the patient may be recommended a period in a cast or a walker boot for 4-6 weeks until their pain has subsided.

Upon removal of the walker boot, advice on the most appropriate supportive footwear is recommended. Strengthening exercises for the foot and ankle are recommended for muscular weakness that develops from the time spent in a boot.

For young patients with flat feet, insoles may be recommended alongside strengthening and stretching exercises.

The prognosis for Kohler’s Disease is positive, with cases resolving within 3 months with treatment & self-resolving in most cases in up to 15 months.
