What Causes Hammertoe Deformity

Overview

A hammertoes is a contracture of the toes as a result of a muscle imbalance between the tendons on the top and the tendons on the bottom of the toe. They can be flexible or rigid in nature. When they are rigid, it is not possible to straighten the toe out by manipulating it. Frequently, they develop corns on the top of the toe as a result of rubbing on the shoe. They may also cause a bothersome callous on the ball of the foot. This occurs as a result of the toe pressing downward on the bone behind the toe. This area then becomes prominent and the pressure of the bone against the ground causes a callous to form.

Causes

Footwear can contribute significantly to the development of hammertoes. Shoes that are too small force your toes into a curled position. Over time, your toe tendons adjust to this positioning, causing your toe or toes to hold a hammered shape. Athletes may be especially susceptible, because of the increased forces on the toes from shoes that are too small or tight. Heel elevation in footwear is also problematic, as it causes your toes to be pushed into the shoe?s toe box. Heel elevation additionally contributes to muscle imbalance. A common example of this is when your Achilles tendon-the tendon at the back of your leg that attaches your calf muscles to your heel bone-is too tight, causing the tendons on the top of your foot that attach to your toes to work too hard and hold your toes in an unnatural, elevated position.

Symptoms

The most obvious symptoms of this injury will be the the middle toe joint is permanently bent at an angle. In the beginning movement may still be possible but as time passes and the injury worsens the toe will be locked in place and possible require hammer toe correction surgery to fix. Another key indicator of hammer toe is that a lump or corn will form on top of the toe. The toe joint will be painful and walking can cause severe discomfort. Occasionally a callus may form on the sole of the injured foot. If you see any of these symptoms together or have been enduring pain for some time, seeing a podiatrist should be your next step.

Diagnosis

Hammer toes may be easily detected through observation. The malformation of the person’s toes begin as mild distortions, yet may worsen over time – especially if the factors causing the hammer toes are not eased or removed. If the condition is paid attention to early enough, the person’s toes may not be permanently damaged and may be treated without having to receive surgical intervention. If the person’s toes remain untreated for too long, however the muscles within the toes might stiffen even more and will require invasive procedures to correct the deformity.

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 hammertoe 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.

Surgical Treatment

For severe hammer toe, you will need an operation to straighten the joint. The surgery often involves cutting or moving tendons and ligaments. Sometimes the bones on each side of the joint need to be connected (fused) together. Most of the time, you will go home on the same day as the surgery. The toe may still be stiff afterward, and it may be shorter. If the condition is treated early, you can often avoid surgery. Treatment will reduce pain and walking difficulty.

Prevention

Good circulation is essential. When you’re sitting down, put your feet up. If you’ve been sitting for a while, stretch your legs and feet. Give yourself a foot massage or trade foot massages with someone you love. A warm foot bath is also a good idea. Most people have one foot that’s bigger than the other. Fit your shoes to the bigger foot. Buy shoes at the end of the day, as feet tend to swell a bit and you will get a better sense of fit. When buying shoes, wear the socks that you will be using when wearing that shoe. For example, wear an athletic sock when buying athletic shoes and a dress sock when purchasing dress shoes. If the shoe does not feel good at the time of purchase, then it will never feel good.

Contracted Toe Tendon Trauma

Overview

Hammer toe deformities can be painful and unsightly. These toe deformities can be the result of a muscle/tendon imbalance or often the end stage result of some systemic disease such as diabetes or arthritis, especially Rheumatoid arthritis. Hammertoe deformities are progressive and can be prevented.

Causes

Hammer toes can be due to a number of things. Several factors are known to increase the risk of developing hammer toes. Some people are just structurally prone to develop hammer toes (hereditary) tight footwear is an important factor in the cause of hammer toes as well as providing the pressure that causes the symptoms, weaker small muscles in the foot may also play a role.

Symptoms

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.

Diagnosis

Your doctor is very likely to be able to diagnose your hammertoe simply by examining your foot. Even before that, he or she will probably ask about your family and personal medical history and evaluate your gait as you walk and the types of shoes you wear. You’ll be asked about your symptoms, when they started and when they occur. You may also be asked to flex your toe so that your doctor can get an idea of your range of motion. He or she may order x-rays in order to better define your deformity.

Non Surgical Treatment

Hammer toes may be effectively corrected in different ways. Treatments can be non-invasive and involve physical therapy along with the advice that the person not wear any more shoes that restrict appropriate space for their toes. Appropriate shoes for people who want to avoid hammer toes, or for people who already have them, should be at least half an inch longer than the person’s longest toe. High-heeled shoes are something to definitely avoid.

Surgical Treatment

Bone-mending procedures realign the contracted toe by removing the entire deviated small joints of the toe (again, not at the ball of the foot). This allows for the buckled joint to be positioned flat and the bone ends to mend together. Often surgical hardware (fixation) is necessary to keep the bones steady during healing. Hardware options hammertoes can involve a buried implant inside the toe, or a temporary wire that is removed at a later date. Medical terminology for this procedure is called a proximal interphalangeal joint arthrodesis (fusion), or a distal interphalangeal joint arthrodesis (fusion), with the former being performed in a high majority of cases.
