Overview
Hammertoe and mallet toe are two foot deformities that occur most often in women who wear high heels or shoes with a narrow toe box. These types of footwear may force your toes against the front of the shoe, causing an unnatural bending. A hammertoe has an abnormal bend in the middle joint of a toe. Mallet toe affects the joint nearest the toenail. Hammertoe and mallet toe are most likely to occur in the toe next to your big toe. Relieving the pain and pressure of hammertoe and mallet toe may involve changing your footwear and wearing shoe inserts. If you have a more severe case of hammertoe or mallet toe, you may need surgery to experience relief.

Causes
Your toe contains two joints that allow it to bend at the middle and bottom. A hammertoe occurs when the middle joint becomes dislocated. Common causes of this joint dislocation include a toe injury, arthritis, a high foot arch, wearing shoes that don?t fit properly, tightened ligaments or tendons in the foot, pressure from a bunion (when your big toe points inward toward your second toe) Spinal cord or peripheral nerve damage may cause all of your toes to curl downward.

Symptoms
People with a hammer toe will often find that a corn or callus will develop on the top of the toe, where it rubs against the top of the footwear. This can be painful when pressure is applied or when anything rubs on it. The affected joint may also be painful and appear swollen.

Diagnosis
Hammertoes are progressive, they don?t go away by themselves and usually they will get worse over time. However, not all cases are alike, some hammertoes progress more rapidly than others. Once your foot and ankle surgeon has evaluated your hammertoes, a treatment plan can be developed that is suited to your needs.

Non Surgical Treatment
Treatment for a hammertoe usually depends on the stage of the hammertoe and the cause of the condition. If your toe is still bendable, your doctor may suggest conservative care-relieving pressure with padding and strapping, or proper shoes that have a deep toe box and are of adequate length and width. Early intervention can often prevent the need for surgery.

Surgical Treatment
If your toe is not bendable, your doctor may recommend surgery. The type of surgery that will be performed will depend on the severity of the condition. You should expect blood and urine studies before the procedure, as well as x-rays of your feet. Your doctor will inject either a local or regional anesthetic. If your toe has some flexibility, the doctor may be able to straighten it by simply making an incision in the toe to release or lengthen the tendon. If the toe is not flexible, your doctor will probably make the same incision to release the tendon, but he or she may also remove some pieces of the bone so that the bone can be straightened. A k-wire is placed in the toe to help hold it straight while it is healing. This is taken out after about four weeks.

Overview
A Hammertoes is a term that is commonly used to describe any type of toe deformity. It is a common problem that may or may not be a problem. What does a hammer toe look like? In a hammertoe the deformity usually exists in one toe (at the proximal inter phalangeal joint) - the base of the toe points upward and the end of the toe points down.

Causes
The cause of hammertoes varies, but causes include genetics, arthritis and injury to the toe. Treatment for hammertoes depends on the severity and can include anti-inflammatory medication, metatarsal pads, foot exercises and better-fitting shoes. If the pain caused by a hammertoe is so severe that wearing a shoe is uncomfortable, surgery may be necessary. Typically this surgery is an outpatient procedure that doesn?t require general anesthesia, though it is an option. Recovery from surgery usually takes a few weeks, and patients are given special shoes to wear.

Symptoms
A hammertoe may be present but not always painful unless irritated by shoes. One may have enlarged toe joints with some thickened skin and no redness or swelling. However, if shoes create pressure on the joint, the pain will usually range from pinching and squeezing to sharp and burning. In long standing conditions, the dislocated joints can cause the pain of arthritis.

Diagnosis
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
Hammertoes that are not painful (asymptomatic) and still flexible may not require treatment. In mild cases, open-toed, low-heeled, or wider shoes and foam or moleskin pads can provide symptomatic relief by reducing pressure. Taping (strapping) the affected toe can help to reduce deformity and pain. Physical therapy to instruct patients in exercises that passively stretch tight structures and strengthen weak foot intrinsic muscles is also helpful with mild cases. Periodic trimming (debridement) of corns (clavi, helomata) by a podiatrist can provide temporary relief. Corticosteroid injections are often very effective in reducing pain.

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 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.

Prevention
You can avoid many foot, heel and ankle problems with shoes that fit properly. Here's what to look for when buying shoes. Adequate toe room. Avoid shoes with pointed toes. Low heels. Avoiding high heels will help you avoid back problems. Adjustability. Laced shoes are roomier and adjustable.

Overview

A bunion is an abnormal, bony bump that forms on the joint at the base of your big toe. Your big toe joint becomes enlarged, forcing the toe to crowd against your other toes. This puts pressure on your big toe joint, pushing it outward beyond the normal profile of your foot, and resulting in pain. Bunions can also occur on the joint of your little toe (bunionette). Bunions can occur for a number of reasons, but a common cause is wearing shoes that fit too tightly. They can also develop as a result of inherited structural defect, injury, stress on your foot or another medical condition.

Causes
Bunions are most often caused by an inherited faulty mechanical structure of the foot. It is not the bunion itself that is inherited, but certain foot types that make a person prone to developing a bunion. Although wearing shoes that crowd the toes won?t actually cause bunions, it sometimes makes the deformity get progressively worse. Symptoms may therefore appear sooner.
SymptomsSymptoms of a bunion include irritated skin, sensitivity to touch, and pain when walking or running. Since the bunion may grow so prominent as to affect the shape of the foot, shoes may no longer fit properly, and blisters may form at the site of friction and pressure. Bunions may grow so large that an individual must wear shoes that are a larger size than they would otherwise wear. If the bunion becomes a severe case, walking may become difficult.

Diagnosis
Before examining your foot, the doctor will ask you about the types of shoes you wear and how often you wear them. He or she also will ask if anyone else in your family has had bunions or if you have had any previous injury to the foot. In most cases, your doctor can diagnose a bunion just by examining your foot. During this exam, you will be asked to move your big toe up and down to see if you can move it as much as you should be able to. The doctor also will look for signs of redness and swelling and ask if the area is painful. Your doctor may want to order X-rays of the foot to check for other causes of pain, to determine whether there is significant arthritis and to see if the bones are aligned properly.

Non Surgical Treatment
This is probably the most important step. Wearing the right footwear can help reduce stress on a minor deformity and reduce the likelihood of it progressing. Recommendations are that the forefoot easily fits within the width of the shoe and there is adequate cushioning and arch support. Soft materials such as smooth leather, suede or fabric will also help to reduce irritation to the area. The podiatrist plays an invaluable role in managing patients with bunions. This is because they can offer a number of options to the patient that can help relieve pain and reduce the severity of the deformity. They can also reduce pressure on skin lesions that develop as a result of the biomechanical changes. Podiatrists can prescribe customised orthotic devices that help reduce the stress on a bunion and control biomechanical factors which cause them. These may be used in conjunction with bunion splints or cushions to further offload the area. Evidence has shown a significant reduction in pain with the use of customized orthotic devices.


Surgical Treatment
There are many different procedures that have been described to correct bunions. The type of operation your foot surgeon recommends to correct your bunion should be dictated by the severity of your bunion deformity and the surgeon?s preference. There are well over 100 different bunion correction procedures described in the orthopaedic literature. However, the broad categories of bunion correction procedures are listed below. Removal of the medial eminence. Distal metatarsal osteotomy (chevron) with great toe soft-tissue tightening (medial capsular tightening and distal soft-tissue repair). Proximal metatarsal osteotomy Ludloff, Cresentic, SCARF, medial opening wedge) with with great toe soft-tissue tightening (medial capsular tightening and distal soft-tissue repair). Lapidus hallux valgus correction (first tarsometatarsal joint fusion) with distal soft tissue procedure. Great Toe Fusion (1st MTP joint arthrodesis). Akin osteotomy (Realignment bone cut at the base of the big toe). Removal of the medial eminence with suture stabilization of the first and second metatarsals. Keller joint arthroplasty (removal of the proximal aspect of the proximal phalanx).

Overview

A bunion is a deformity of the metatarsophalangeal (MTP) joint at the base of the big toe. A bunion develops when the first metatarsal bone of the foot turns outward and the big toe points inward (toward the other toes), causing the joint to jut out. A bunion is most likely to develop when susceptible feet are repeatedly squeezed into narrow, pointed-toe footwear. The big toe pushes against the other toes, sometimes diving over or under them. As a result, the base of the big toe ? the metatarsophalangeal (MTP) joint ? juts or angles out from the foot.

Causes
Bunions are a common problem that can cause foot pain and difficulty wearing shoes. Bunions occur in about 30% of the population of most Western countries. They are seen most commonly in women and become more common as people get older. Patients with bunions generally have one of two problems that can cause pain. As the big toe becomes more and more angled (pointing toward the other toes), the base of the toe becomes more and more prominent, forming the bunion. The bunion forms in part because of the new angle of the toe, and in part due to inflammation over the bunion surface. As the inflammation worsens, people can experience pain with shoe wear and walking. The big toe may eventually come to lie over, or more commonly under, the second toe. This may cause further irritation while wearing shoes and more pain. The second toe of patients who have bunions commonly forms a hammer toe.
SymptomsA bunion, also called a hallux valgus, is a bony prominence on the inside of the big toe, caused by a misalignment of the joint. The overlying skin maybe swollen, red and tender. Bunions are often painful and can limit what shoes you can wear.

Diagnosis
Although bunions are usually obvious from the pain and unusual shape of the toe, further investigation is often advisable. Your doctor will usually send you for X-rays to determine the extent of the deformity. Blood tests may be advised to see if some type of arthritis could be causing the pain. Based on this evaluation, your doctor can determine whether you need orthopaedic shoes, medication, surgery or other treatment.

Non Surgical Treatment
When the deformity is mild, treatment is usually not necessary. However, changing shoes to ones that have little or no heel, and are wider in the toe area (toe box) will be more comfortable and may help to prevent worsening of the bunion deformity. If the bunion starts to become painful, other measures may help. Bunions can cause pain in several different areas. The medial eminence may be painful, the entire first toe joint may hurt, or there may be pain underneath some or all of the forefoot (the ball of the foot). Pain over the medial eminence is the most common problem that affects bunion patients. A ?toe spacer? can be placed between the first and second toes and can provide some pain relief as it straightens out the bunion slightly. Pads placed over the medial eminence itself are hard to keep in place and rarely help to relieve pain. Pain underneath the first toe or lesser toes can be relieved by pads placed in the shoes in precise areas. The pads help to take pressure off the prominent areas on the bottom of the foot. Generalized measures to relieve bunion pain, such as physical therapy or foot stretching exercises, have not been shown to be helpful. Orthotics are often prescribed, but are also rarely helpful in relieving pain over the bunion, but may help with pain felt under the ball of the foot.


Surgical Treatment
Bunion surgery is most often performed as an out-patient, this means you go home that same day. It will likely be done at a hospital or out-patient (ambulatory) surgery center. The anesthetic choices with bunion surgery are local with sedation, spinal or general anesthesia. You wouldn?t expect that a small bunion would be treated exactly the same as a large one. Over the years, surgeons have developed dozens of methods to surgically correct bunions. But don?t worry because only a handful of methods are used today. With most bunion surgeries today, the procedure involves a combination of soft-tissue rebalancing of ligaments and tendons as well as bone work to re-align the foot structure. You may have heard people say they had their ?bunion shaved.? In most cases, the surgery often involves much more than simply shaving the bunion. The shaving part of the procedure is called an ?exostectomy? and often performed in conjunction with other methods.

Prevention
Wear insoles and well-fitting shoes to help slow down the progression of bunions and alleviate discomfort. Cushioning can also help alleviate discomfort. Consider wearing shoes with a wide toe box so they don't crowd your toes. Children can also develop bunions and should wear properly fitting shoes as their feet are still developing.
