Hammer toes is caused when the middle joint (PIP) bends down towards the floor (flexion). To compensate, the joints above and below (MTP, DIP) bend up (hyperextend). The result is that the middle part of the toe lifts up. Hammertoe is the most common deformity of the lesser toes (i.e. not the big toe). It tends to only affect one toe, most commonly the second.
Hammer toes are most frequently caused by a muscle - tendon imbalance in the foot, and are seen both in adults and children. Foot muscles work in pairs to straighten and bend the toes. If your foot has a biomechanical defect, the muscles tighten and the tendons shorten. Eventually, the toe muscles can?t straighten the toe, even when barefoot. Contributing factors are poor choices in footwear, arthritis, or trauma.
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.
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
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.
Surgery may not help how your foot looks. And your toe problems may also come back after surgery. This is more likely if you keep wearing the kinds of shoes that cause toe problems. Your expectations will play a large role in how Hammer toes you feel about the results of surgery. If you are only having surgery to improve the way your foot looks, you may not be happy with how it turns out.
