OverviewHammer toes are usually not a serious condition, but can become painful as the bent joint rubs against the inside of the shoe, causing irritation, corns, or calluses on the top of the middle joint or the tip of the toe. A Hammertoe may also cause occasional shooting pains throughout the toes or elsewhere in the foot. A hammertoe has a kink or contracture in its second joint--called the proximal interphalangeal joint--that causes the toe to bend upward in the middle, giving it a hammer-like appearance. The raised part of the toe often rubs on shoes, leading to the formation of corns or calluses. Usually hammertoe affects the smaller toes, causing pain and interfering with the ability to walk normally.
Causes
Hammer toe most frequently results from wearing poorly fitting shoes that can force the toe into a bent position, such as excessively high heels or shoes that are too short or narrow for the foot. Having the toes bent for long periods of time can cause the muscles in them to shorten, resulting in the hammer toe deformity. This is often found in conjunction with bunions or other foot problem (e.g., a bunion can force the big toe to turn inward and push the other toes). It can also be caused by muscle, nerve, or joint damage resulting from conditions such as osteoarthritis, rheumatoid arthritis, stroke, Charcot-Marie-Tooth disease, complex regional pain syndrome or diabetes. Hammer toe can also be found in Friedreich's ataxia.
Symptoms
Hammertoe and mallet toe feature an abnormal bend in the joints of one or more of your toes. Moving the affected toe may be difficult or painful. Corns and calluses can result from the toe rubbing against the inside of your shoes. See your doctor if you have persistent foot pain that affects your ability to walk properly.
Diagnosis
First push up on the bottom of the metatarsal head associated with the affected toe and see if the toe straightens out. If it does, then an orthotic could correct the problem, usually with a metatarsal pad. If the toe does not straighten out when the metatarsal head is pushed up, then that indicates that contracture in the capsule and ligaments (capsule contracts because the joint was in the wrong position for too long) of the MTP joint has set in and surgery is required. Orthotics are generally required post-surgically.
Non Surgical Treatment
For hammertoes that are still flexible, a podiatrist might recommend padding or taping the toes to relieve pain and orthotic inserts for shoes to minimize pressure and keep the toe properly aligned. Anti-inflammatory drugs or corticosteroid injections can relieve pain and inflammation. For more advanced cases of hammertoe, a podiatrist might recommend a surgical procedure to cut the tendon, allowing the toe to straighten. For hammertoes that have become rigid, a more complicated surgery might be needed, during which the podiatrist removes part of the bone at the deformed joint to allow it to straighten.
Surgical Treatment
Treatment of a severe hammertoe that has become rigid includes surgery. What is done during the surgery depends on how misshapen and inflexible the toe is. The surgeon may make a cut over your toe and release the tendon by cutting the tendon away from the bone. The surgeon may remove a small piece of bone from the toe. The surgeon may realign the tendons to reposition your toe or fasten the bones with pins. Sometimes the surgeon may have to join the bones in the toe. In this case, you will no longer be able to bend the toe, but the toe will be flat.
Prevention
wear sensible shoes. Here are some tips. Most people have one foot that's bigger than the other. Fit your shoes to the bigger foot. Buy your shoes at the end of the day as your feet tend to swell a bit and you will get a better sense of fit. When you buy your shoes, wear the sock that you will be using when wearing that shoe - wear a sports sock when buyingtrainers, for example. As you get older, your feet get bigger. Get your feet measured every time you buy shoes. Don't go by shoe sizes. Shoe sizes vary among manufacturers; a shoe is the right size only when it fits comfortably. The ball of your foot should fit into the widest part of the shoe. A shoe should be sturdy so that it only bends in the ball of the foot, exactly where your big toes bend. Any shoe that can be bent anywhere along the sole or twisted side to side is generally too flimsy. There should be at least 1.5 cm between the tip of your longest toe and the front of the shoe. Never buy shoes that feel tight and expect them to stretch with wearing. If you have prominent areas on your feet such as hammer toes and bunions, avoid shoes with a lot of stitching or multiple pieces of fabric, as these stitched areas tend not to stretch to accommodate various toe deformities. Your shoes shouldn't ride up and down on your heel as you walk. The higher the heel, the less safe the shoe. Check children's shoes regularly.
