"You can replace that?" Everyone knows that hips and knees can be replaced but it is not as widely known that ankles and big toe joints can also be replaced. I was surprised during a recent conversation with a primary care physician (PCP) when they didn't know that joint replacements were possible in the foot and ankle. If physicians aren't aware of the options that advancements in technology have allowed, I can only assume that very few patients know of these options. Arthritis can cause pain and limitation of motion at the ankle and great toe joint. These 2 joints are extremely important when it comes to walking and normal gait mechanics. Treatment options for early arthritic changes include pain medications, antiinflammatories, orthotics, joint injections, shoe changes and physical therapy. For advanced arthritis surgical options include joint fusion or replacement. The benefit of replacing a joint is that it helps preserve motion allowing for a more normal step when walking. Only a foot and ankle surgeon can determine if a patient is a candidate for ankle or great toe joint replacement. |

Bunions are not just the nasty bump you saw sticking out of the side of your grandmother’s shoe. They are a progressive foot deformity that can appear as early as the teen years. Over time the great toe moves toward the smaller toes, making the great toe joint prominent on the inside of the foot. Bunions are hereditary and the deformity can be worsened by pointy toed shoes.
In the early stages there is no pain with this deformity. As a bunion progresses shoes become irritating to the bump. Patients will usually start to wear wider shoes to accommodate the bump, and stretching out of the shoe over the bunion can be seen. With the joint out of alignment the cartilage will start to degenerate and become arthritic. Pain changes from an irritation over the bump from shoes to a deeper ache in the joint as the cartilage is destroyed. If a bunion is not treated, compensation can be seen throughout the foot. Hammertoe formation of the second toe is caused by the great toe pushing the second toe out of position. Callouses can be seen across the forefoot and along the great toe as the mechanics of the foot and the way a step is taken changes because of the deformity.
Treatment early on for bunions includes orthotics. An orthotic is a shoe insert that controls the mechanics/function of the foot and its joints. Podiatrist recomment using an orthotic early on to slow down progression of a bunion deformity and ease pain. This is important in juvenile bunions where surgery runs the risk of disrupting the growth plates.
The type of surgery necessary to correct a bunion depends on the severity of the deformity. It is generally an outpatient procedure, where the patient can go home the same day the procedure is performed. The majority of bunion procedures allow the patient to walk in a special shoe or protective boot immediately after surgery. No high impact activity (such as jogging or aerobics) is allowed until the bone heals which generally takes 6-8 weeks. Very severe bunions may require a cast and several weeks on crutches. Physical therapy after surgery helps restore motion to the joint and ensures the patient walks without a limp.
If a bunion is neglected and allowed to progress, the joint becomes arthritic. Treatment options include arthritis medicines to control the pain and stiff soled shoes to limit motion at the joint. Surgical treatments include joint replacement and fusion/arthrodesis. Joint replacement maintains motion at the great toe joint placing a piece of metal to give a smooth surface for the joint to glide. Joint replacement patients can start walking inmmediately after surgery. Joint arthrodesis fuses the great toe to the long bone behind it, eliminating motion and pain. Joint fusion takes 6-8 weeks for the bone to heel and a cast and crutches are used during this time.
Ideally, bunions should be treated before the joint becomes arthiritic. Maintaining alignment of the joint will prevent deterioration of the cartilage and the pain associated with arthritis.
