A Hammer toes is a deformity of the second, third or fourth toes in which the main toe joint is bent upward like a claw. Initially, hammertoes are flexible and can be corrected with simple measures. Left untreated, they can become fixed and require surgery. Hammertoe results from shoes that don?t fit properly or a muscle imbalance, usually in combination with one or more other factors. Muscles work in pairs to straighten and bend the toes. If the toe is bent and held in one position long enough, the muscles tighten and can?t stretch out.
If a foot is flat (pes planus, pronated), the flexor muscles on the bottom of the foot can overpower the others because a flatfoot is longer than a foot with a normal arch. When the foot flattens and lengthens, greater than normal tension is exerted on the flexor muscles in the toes. The toes are not strong enough to resist this tension and they may be overpowered, resulting in a contracture of the toe, or a bending down of the toe at the first toe joint (the proximal interphalangeal joint) which results in a hammertoe. If a foot has a high arch (pes cavus, supinated), the extensor muscles on the top of the foot can overpower the muscles on the bottom of the foot because the high arch weakens the flexor muscles. This allows the extensor muscles to exert greater than normal tension on the toes. The toes are not strong enough to resist this tension and they may be overpowered, resulting in a contracture of the toe, or a bending down of the toe at the first toe joint (the proximal interphalangeal joint) which results in a hammertoe.
The most common symptoms of hammertoes include. The toe is bent upward at the middle toe joint, so that the top of this joint rubs against the top of the shoe. The remainder of the toe is bent downward. Pain upon pressure at the top of the bent toe from footwear. The formation of corns on the top of the joint. Redness and swelling at the joint contracture. Restricted or painful motion of the toe joint. Pain in the ball of the foot at the base of the affected toe. This occurs because the contracted digit puts pressure on the metatarsal head creating callouse and pressure on the ball of the foot.
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
Conservative treatment is the first choice, often starting with a change of shoes to ones that have soft, larger toe spaces. Toe exercises may be prescribed to stretch and strengthen the toe muscles. Over-the-counter straps, cushions or non-medicated corn pads may be recommended to help relieve your symptoms.
Probably the most frequent procedure performed is one called a Post or an Arthroplasty. In this case a small piece of bone is removed from the joint to straighten the toe. The toe is shortened somewhat, but there is still motion within the toe post-operatively. In other cases, an Arthrodesis is performed. This involves fusing the abnormally-contracted joint. The Taylor procedure fuses only the first joint in the toe, whereas the Lambrinudi procedure fuses both joints within the toe. Toes which have had these procedures are usually perfectly straight, but they take longer to heal and don’t bend afterwards. A Hibbs procedure is a transfer of the toe’s long extensor tendon to the top of the metatarsal bone. The idea of this procedure is to remove the deforming cause of the hammertoes (in this case, extensor substitution), but to preserve the tendon’s function in dorsifexing the foot by reattaching it to the metatarsals. Fortunately, the Gotch (or Gotch and Kreuz) procedure–the removal of the base of the toe where it attaches to the foot, is done less frequently than in years past. The problem with this procedure is that it doesn’t address the problem at the level of the deformity, and it causes the toe to become destabilized, often resulting in a toe that has contracted up and back onto the top of the foot. You can even have an Implant Arthroplasty procedure, where a small, false joint is inserted into place. There are several other procedures, as well.
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.
