Hammer Toes What Causes Them

Overview

Hammer toe is foot deformity that typically affects second, third or fourth toes. The condition is called hammertoe because of the unnatural position your toes form. Hammertoe causes your toe to bend upward at the middle joint in a way that looks similar to a hammer. While it may not be painful at first, this condition usually worsens with time and it becomes difficult to extend your toes. Sometimes, calluses or corns form in association with hammertoe.

Causes

If a foot is flat (pes planus, pronated), the flexor muscles on the bottom of the foot can overpower the others because a flatfoot is longer than a foot with a normal arch. When the foot flattens and lengthens, greater than normal tension is exerted on the flexor muscles in the toes. The toes are not strong enough to resist this tension and they may be overpowered, resulting in a contracture of the toe, or a bending down of the toe at the first toe joint (the proximal interphalangeal joint) which results in a hammertoe. If a foot has a high arch (pes cavus, supinated), the extensor muscles on the top of the foot can overpower the muscles on the bottom of the foot because the high arch weakens the flexor muscles. This allows the extensor muscles to exert greater than normal tension on the toes. The toes are not strong enough to resist this tension and they may be overpowered, resulting in a contracture of the toe, or a bending down of the toe at the first toe joint (the proximal interphalangeal joint) which results in a hammertoe.

Symptoms

The most common symptoms of hammertoes include. The toe is bent upward at the middle toe joint, so that the top of this hammertoe 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.

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

In the earlier stages of hammer toe, when the toes can still be manually straightened, then conservative treatment is appropriate. This means wearing shoes which are a half size bigger than normal and which are not narrow around the toes. Exercises to stretch the toes out and strengthen the muscles under the foot which balances the tightness of the top tendons are important. Padding or corn plasters can be used to ease the discomfort of any associated corns and calluses.

Surgical Treatment

Joint resection procedures involves removing part of one of the two small joints of the toe directly underneath where the digit is crooked. The purpose is to make room for the toe to be re-positioned flat or straight. Because hammer toes become rigid or fixed with time, removing the joint becomes the only option when the knuckle is stiff. Its important to understand that this procedure does not involve the joint of the ball of the foot, rather the a small joint of the toe. Medical terminology for this procedure is called a proximal interphalangeal joint arthroplasty or a distal interphalangeal joint arthroplasty, with the latter involving the joint closer to the tip of the toe.

Contracted Toe Causes

Overview

hammertoe is the general term used to describe an abnormal contraction or “buckling” of the toe because of a partial or complete dislocation of one of the joints of the toe or the joint where the toe joins with the rest of the foot. As the toe becomes deformed, it rubs against the shoe and the irritation causes the body to build up more and thicker skin to help protect the area. The common name for the thicker skin is a corn.

Causes

A common cause of hammertoe and mallet toe is wearing improper footwear – shoes that are too tight in the toe box, or high-heel shoes. Wearing shoes of either type can push your toes forward, crowding one or Hammer toe more of them into a space that’s not large enough to allow your toes to lie flat. Hammertoe and mallet toe deformities can also be inherited and may occur despite wearing appropriate footwear. The result is a toe that bends upward in the middle and then curls down in a hammer-like or claw-like shape. Your shoes can rub against the raised portion of the toe or toes, causing painful corns or calluses. The bottom of the affected toe can press down, creating the mallet-like appearance of mallet toe. At first, a hammertoe or mallet toe may maintain its flexibility and lie flat when you’re not wearing crowded footwear. But eventually, the tendons of the toe may contract and tighten, causing your toe to become permanently stiff.

Symptoms

Well-developed hammertoes are distinctive due to the abnormal bent shape of the toe. However, there are many other common symptoms. Some symptoms may be present before the toe becomes overly bent or fixed in the contracted position. Often, before the toe becomes permanently contracted, there will be pain or irritation over the top of the toe, particularly over the joint. The symptoms are pronounced while wearing shoes due to the top of the toe rubbing against the upper portion of the shoe. Often, there is a significant amount of friction between the toe and the shoe or between the toe and the toes on either side of it. The corns may be soft or hard, depending on their location and age. The affected toe may also appear red with irritated skin. In more severe cases, blisters or open sores may form. Those with diabetes should take extra care if they develop any of these symptoms, as they could lead to further complications.

Diagnosis

Your healthcare provider will examine your foot, checking for redness, swelling, corns, and calluses. Your provider will also measure the flexibility of your toes and test how much feeling you have in your toes. You may have blood tests to check for arthritis, diabetes, and infection.

Non Surgical Treatment

You can usually use over-the-counter cushions, pads, or medications to treat bunions and corns. However, if they are painful or if they have caused your toes to become deformed, your doctor may opt to surgically remove them. If you have blisters on your toes, do not pop them. Popping blisters can cause pain and infection. Use over-the-counter creams and cushions to relieve pain and keep blisters from rubbing against the inside of your shoes. Gently stretching your toes can also help relieve pain and reposition the affected toe.

Surgical Treatment

Toes can be surgically realigned and made straight again. They can even be made shorter. The good news is that toes can be corrected. Hammer toe surgery is often synonymous with ?toe shortening?, ?toe job? and/or ?toe augmentation?. Depending on the severity and length of the toe, there are several methods to surgically correct a hammer toe. In general, the surgery involves removing a portion of the bone at the contracted joint, to realign the toe.

Prevention

Prevention of a hammer toe can be difficult as symptoms do not usually start until the problem is well established. Wearing shoes that have extra room in the toes may help the problem or slow down its development.

Do Bunions Need Surgical Procedures?

Overview

A bunion is a bony bump that forms on the joint at the base of your big toe. A bunion forms when your big toe pushes against your next toe, forcing the joint of your big toe to get bigger and stick out. The skin over the bunion might be red and sore. Wearing tight, narrow shoes might cause bunions or might make them worse. Bunions can also develop as a result of an inherited structural defect, stress on your foot or a medical condition, such as arthritis. Smaller bunions (bunionettes) also can develop on the joint of your little toes.

Causes
While the precise cause is not known, there seem to be inherited (genetic) factors that lead to abnormal foot function like overpronation that can predispose to the development of bunions. This is especially common when bunions occur in younger individuals. This abnormal biomechanics can lead to instability of the metatarsal phalangeal joint and muscle imbalance resulting in the deformity. Although shoe gear doesn’t directly cause a bunion, it can certainly make the bunion painful and swollen. Other less common causes of bunion deformities include trauma (sprains, fractures, and nerve injuries), neuromuscular disorders (polio or Charcot-Marie-Tooth disease) and limb-length discrepancies (one leg shorter than the other) where the longer leg develops the bunion.
SymptomsA bulging bump on the outside of the base of your big toe. Swelling, redness or soreness around your big toe joint aggravated by footwear. Red, calloused skin along the inside edge of the big toe. Corns or calluses under the ball of the foot or where the first and second toes overlap. Persistent or intermittent pain. Restricted movement of your big toe.

Diagnosis
Generally, observation is adequate to diagnose a bunion, as the bump is obvious on the side of the foot or base of the big toe. However, your physician may order X-rays that will show the extent of the deformity of the foot.

Non Surgical Treatment
Several things can be done to help relive the pain of bunions. These won’t make the bunion go away, but they can make the foot more comfortable. Wearing different shoes. Shoes with a wide toe box rather than a pointed one will help. Shoes with lower heels will also help. (High heels throw more of the body’s weight on the front part of the foot where the toe joints are.) Padding. Pads placed over the bunion may help reduce the pain. These are available from a drug store or may be available from a foot and ankle surgeon. Avoiding activities that make the pain worse. This includes standing for a long time or other activities that make the bunion sore. Non-steroidal anti-inflammatory drugs. These include aspirin or ibuprofen. They relieve pain and swelling. Applying an ice pack to reduce swelling and pain. Corticosteroid injections. These are not often used in bunion treatment. Injecting corticosteroids sometimes helps if the bursa is inflamed. (Bursa is a fluid-filled sac within a joint to cushion the bones). Orthotic devices. These are devices placed inside a shoe that shift the positioning of the foot. Orthotics help compensate for structural issues that cause foot problems.

Surgical Treatment
In cases where joint pain and deformity are severe, joint replacement surgery may be recommended. This may particularly be recommended when arthritis is present in the joint. Surgery may be carried out under a local, regional or general anaesthetic. Most cases are performed as a day stay procedure. However, an overnight stay in hospital may be required if the surgery is more extensive. The type of surgery to be performed, the type of anaesthetic to be used and the expected hospital stay should be discussed with your surgeon prior to surgery.

Prevention
Shop for shoes that possess a removable liner, or insole, and stand on the liner after you have removed it from your shoe. This is an effective method to see if your shoe is wide enough in the forefoot to accommodate your bunion. If your bunion and forefoot are wider than the insole, your shoe will squeeze and constrict your bunion and create the symptoms that define this health problem. The insole should also be wide enough to fully accommodate your big toe when it points outward, away from your other toes.
