The Things That Cause Hammer Toes

Overview

Hammer toes is a secondary problem originating from fallen cross arches. The toes start to curl and get pulled backwards, as the collapsed or pushed out metatarsal bones pull the tendons and ligaments, and causes them to get shorter and tighter. This condition causes the toes have higher pressure and they have limited movement and cannot be straightened fully. This can lead to numbness and pain in the toes as muscles, nerves, joints and little ligaments are involved with this condition. As the top part of the toe can rub against the shoe, it can cause corns and calluses.

Causes

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.

Symptoms

People who have painful hammertoes visit their podiatrist because their affected toe is either rubbing on the end their shoe (signaling a contracted flexor tendon), rubbing on the top of their shoe (signaling a contracted extensor tendon), or rubbing on another toe and causing a painful buildup of thick skin, known as a corn.

Diagnosis

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 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.

Surgical Treatment

Probably the most frequent procedure performed is one called a Post or an Arthroplasty. In this case a small piece of bone is removed from the joint to straighten the toe. The toe is shortened somewhat, but there is still motion within the toe post-operatively. In other cases, an Arthrodesis is performed. This involves fusing the abnormally-contracted joint. The Taylor procedure fuses only the first joint in the toe, whereas the Lambrinudi procedure fuses both joints within the toe. Toes which have had these procedures are usually perfectly straight, but they take longer to heal and don't bend afterwards. A Hibbs procedure is a transfer of the toe's long extensor tendon to the top of the metatarsal bone. The idea of this procedure is to remove the deforming cause of the hammertoes (in this case, extensor substitution), but to preserve the tendon's function in dorsifexing the foot by reattaching it to the metatarsals. Fortunately, the Gotch (or hammertoes Gotch and Kreuz) procedure--the removal of the base of the toe where it attaches to the foot, is done less frequently than in years past. The problem with this procedure is that it doesn't address the problem at the level of the deformity, and it causes the toe to become destabilized, often resulting in a toe that has contracted up and back onto the top of the foot. You can even have an Implant Arthroplasty procedure, where a small, false joint is inserted into place. There are several other procedures, as well.
