What are Midfoot Arthritis, What Causes Midfoot Arthritis, and What is the Treatment for Midfoot Arthritis?
Midfoot arthritis is usually defined with pain in the midfoot foot accompanied with skeletal structural changes. The underlining root causes for both AO and RA are different but the manifestations can be very similar. In both cases the articulating joints of the midfoot are being destroyed due force and movement. It often also leads to skeletal changes that can cause further damage. Many patients experience a dull aching pain under the metatarsal heads or on the top of the foot. Excessive movement and standing can makes the condition worse.
As we age the articular cartilage inside the joint space deteriorated, OA; or in the case of RA the joints are being destroyed chemically by the disease, this causes pain and swelling.
Many people try to alleviate the pain caused by arthritis by placing pads under the metatarsal heads or over fitting their shoes to lessen the pressure on the top of the foot. This will help to some degree. Custom foot orthotic should be used to properly support the trans-metatarsal arch and cushion the metatarsal heads. This is also helpful to relieve the excessive pressure that leads to callus formation. Weight should be redistributed equally with the use of an orthotic. The orthotic should also be a total contact device to control and limit as much motion as possible. The orthotic should be made with materials that absorb shock and shear (friction) forces. A custom foot orthotic is not able to fix the pathology, but can very effectively manage it and the symptoms.
