Hammertoes 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.
Hammertoe is caused when muscles fail to work in a balanced manner and the toe joints bend to form the hammertoe shape. If they remain in this position, the muscles and tendons supporting them tighten and stay that way. Causes of hammertoe can include squeezing into a too-small or ill-fitting shoe or wearing high heels that jam your toes into a tight toe box. An injury such as badly stubbing your toe. Arthritis. Nerve and muscle damage from diseases such as diabetes,
Hammer toes can cause problems with walking and lead to other foot problems, such as blisters, calluses, and sores. Pain is caused by constant friction over the top of the toe?s main joint. It may be difficult to fit into some shoe gear due to the extra space required for the deformed toe. In many cases there will be pain on the ball of the foot over the metatarsals along with callus formation. This is due to the toes not functioning properly, failing to properly touch the ground during the gait cycle. The ball of the foot then takes the brunt of the ground forces, which causes chronic pain.
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
Any forefoot problems that cause pain or discomfort should be given prompt attention. Ignoring the symptoms can aggravate the condition and lead to a breakdown of tissue, or possibly even infection. Conservative treatment of mallet toes begins with accommodating the deformity. The goal is to relieve pressure, reduce friction, and transfer forces from the sensitive areas. Shoes with a high and broad toe box (toe area) are recommended for people suffering from forefoot deformities such as mallet toes. This prevents further irritation in the toe area from developing. Other conservative treatment includes forefoot supports such as gel toe caps, gel toe shields and toe crests. Gel forefoot supports provide immediate comfort and relief from common forefoot disorders without drying the skin.
Surgery is used when other types of treatment fail to relieve symptoms or for advanced cases of hammertoe. There are several types of surgeries to treat hammertoe. A small piece of bone may be removed from the joint (arthroplasty). The toe joint may be fused to straighten it (arthrodesis). Surgical hardware, such as a pin, may be used to hold the bones in place while they heal. Other types of surgery involve removing skin (wedging) or correcting muscles and tendons to balance the joint.
