hammertoe can occur when feet are crammed into shoes so tight that the front of the toes are pushed against the front of the shoes for prolonged periods of time. One or more toes then remain bent with the middle knuckle pointing up, even when shoes are taken off. If the condition is left untreated and tight footwear is continually worn, these bent toes can become so rigid that they can no longer straighten out on their own. While any shoes that are too tight can lead to this condition, high heels seem to be a big culprit since the elevated ankle causes more weight to push the toes forward. This may explain why the condition affects more women than men.
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 hammertoes toe, or a bending down of the toe at the first toe joint (the proximal interphalangeal joint) which results in a hammertoe.
If the toes remain in the hammertoe position for long periods, the tendons on the top of the foot will tighten over time because they are not stretched to their full length. Eventually, the tendons shorten enough that the toe stays bent, even when shoes are not being worn. The symptoms of hammertoe include a curling toe, pain or discomfort in the toes and ball of the foot or the front of the leg, especially when toes are stretched downward, thickening of the skin above or below the affected toe with the formation of corns or calluses, difficulty finding shoes that fit well. In its early stages, hammertoe is not obvious. Frequently, hammertoe does not cause any symptoms except for the claw-like toe shape.
The exam may reveal a toe in which the near bone of the toe (proximal phalanx) is angled upward and the middle bone of the toe points in the opposite direction (plantar flexed). Toes may appear crooked or rotated. The involved joint may be painful when moved, or stiff. There may be areas of thickened skin (corns or calluses) on top of or between the toes, a callus may also be observed at the tip of the affected toe beneath the toenail. An attempt to passively correct the deformity will help elucidate the best treatment option as the examiner determines whether the toe is still flexible or not. It is advisable to assess palpable pulses, since their presence is associated with a good prognosis for healing after surgery. X-rays will demonstrate the contractures of the involved joints, as well as possible arthritic changes and bone enlargements (exostoses, spurs). X-rays of the involved foot are usually performed in a weight-bearing position.
Non Surgical Treatment
Putting padding between your toes and strapping them in place can help to stop pain caused by the toes rubbing. Custom-made insoles for your shoes will help to take the pressure off any painful areas. Special shoes that are wider and deeper than normal can stop your toes rubbing. However if your pain persists your consultant may recommend an surgery.
There are several surgical techniques used to treat hammertoes. When the problem is less severe, the doctor will remove a small piece of bone at the involved joint and realign the toe joint. More severe hammer toes may need more complicated surgery.
