Hammer toe is a Z-shaped deformity caused by dorsal subluxation at the metatarsophalangeal joint. Diagnosis is clinical. Treatment is modification of footwear and/or orthotics. The usual cause is misalignment of the joint surfaces due to a genetic predisposition toward aberrant foot biomechanics and tendon contractures. RA and neurologic disorders such as Charcot-Marie-Tooth disease are other causes.
People who have a high-arched feet have an increased chance of hammer toes occurring. Also, patients with bunion deformities notice the second toe elevating and becoming hammered to make room for the big toe that is moving toward it. Some patients damage the ligament that holds the toe in place at the bottom of the joint that connects the toe and foot. When this ligament (plantar plate) is disrupted or torn, the toe floats upward at this joint. Hammer toes also occur in women wearing ill-fitting shoes or high heels, and children wearing shoes they have outgrown.
The middle joint of the toe is bent. The end part of the toe bends down into a claw-like deformity. At first, you may be able to move and straighten the toe. Over time, you will no longer be able to move the toe. It will be painful. A corn often forms on the top of the toe. A callus is found on the sole of the foot. Walking or wearing shoes can be painful.
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 Hammer toes Surgical Treatment
There are several treatment options. These are based on how severe the problem has become. The sooner a person seeks treatment, the more options that person may have. Wear properly fitting shoes; this does not necessarily mean expensive shoes. Padding any prominent areas around the bony point of the toe may help to relieve pain. Medication that reduces inflammation can ease the pain and swelling. Sometimes a doctor will use cortisone injections to relieve acute pain. A podiatrist may also custom-make an insert to wear inside your shoe. This can reduce pain and keep the hammer toe from getting worse. Your doctor may recommend foot exercises to help restore muscle balance. Splinting the toe may help in the very early stages.
Several surgical procedures are available to the podiatric physician. For less severe deformities, the surgery will remove the bony prominence and restore normal alignment of the toe joint, thus relieving pain. Severe hammertoes, which are not fully reducible, may require more complex surgical procedures. Recuperation takes time, and some swelling and discomfort are common for several weeks following surgery. Any pain, however, is easily managed with medications prescribed by your podiatric physician.
Some different things you can do to help prevent hammer toes from forming and progressing do exist. You can wear supportive shoes to help prevent deformities. Hammer toes are often times related to poor foot mechanics, particularly foot flattening. You can wear custom orthotics prescribed by a podiatrist; orthotics might prevent or slow the progression of hammer toes. You can also avoid shoes with narrow or pointed toe boxes that can compress your toes.
