What is arthroereisis?

Arthroereisis is a procedure that uses special implants to help treat flat feet and to prevent the problems flat feet can cause. During treatment, special implanted devices are inserted into the area of the heel and ankle called the subtalar region. These implants help promote normal, comfortable movement by stabilizing the subtalar joint. Arthroereisis is most commonly performed in children whose feet and ankles are still growing, but in some cases, it may also be used in adults.

What are the symptoms of flat feet?

In a normally-shaped foot, the arch portion creates a curve on the bottom of the foot to provide support for the midfoot region. In a person with flat feet, the arch is absent or far less pronounced, making the midfoot more prone to pain, irritation, inflammation and injury. Many people with flat feet also have what is called “excessive pronation” or “overpronation” of the foot, a type of gait that causes the foot to “roll” inward and the heel to “evert” or turn outward.

What are the benefits of arthroereisis?

Arthroereisis offers several benefits for patients with flat feet. First, because it relies on implants, the procedure is easily reversible, and no drilling or bone removal is required. Patients can experience improved gait mechanics and a more normal appearance when walking while also relieving discomfort and fatigue caused by excessive pronation.

How is arthroereisis performed?

During the procedure, a small incision is made in the foot over the subtalar region. A special guide is used to ensure the implant will be placed properly, and the correct size of the implant is determined. The implant is inserted using a special guide wire, and then the incision is closed with sutures. A cast will be worn for a few weeks during the initial stages of healing, and crutches will also be needed. Over time, the body’s tissue will grow around the implant helping to stabilize it.
