Hammertoes usually start out as mild deformities and get progressively worse over time. In the earlier stages, hammertoes are flexible and the symptoms can often be managed with changes in shoe styles and foot care products. But if left untreated, hammertoes can become more rigid and painful. Corns are more likely to develop as time goes on-and corns never really go away, even after trimming. In more severe cases of Hammer toes, corn lesions may evolve into severe ulcerations. These lesions frequently occur in patients who have vascular disease or are Diabetic with neuropathy. The ulcerations can extend to the bone and result in infection and possible loss of digit or amputation.
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 hammertoes 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.
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.
Most health care professionals can diagnose hammertoe simply by examining your toes and feet. X-rays of the feet are not needed to diagnose hammertoe, but they may be useful to look for signs of some types of arthritis (such as rheumatoid arthritis) or other disorders that can cause hammertoe.
Non Surgical Treatment
People with a hammer toe benefit from wearing shoes in which the toe box is made of a flexible material and is wide enough and high enough to provide adequate room for the toes. High-heeled shoes should be avoided, because they tend to force the toes into a narrow, flat toe box. A doctor may recommend an insert (orthotic) for the shoe to help reduce friction and pressure on the hammer toe. Wearing properly fitted shoes may reduce pain and inflammation. It may also prevent ulcers from developing and help existing ulcers heal. However, the hammer toe does not disappear.
There are generally two methods surgeons use to correct hammer toes, they are joint resection (arthroplasty) or bone mending (fusion), and the location where this is performed on the toe depends on where the toe is buckled. Its important to recognize that most of the surgical work involved the joints of the toe, not the joint of the ball of the foot. Sometimes a toe relocation procedure is needed when the joint of the ball of the foot is malaligned (subluxed or dislocated).
Custom orthotics paired with a well made shoe can prevent the progression and development of hammertoes. Wearing proper-fitting shoes and custom orthotic devices can provide the support patients need to address muscle/tendon dysfunction. It can also support end stage diseases that result in hammertoe deformities by re-balancing the foot and ankle and controlling the deforming forces.
