Overview
There are two different types of Hammer Toe. Flexible Hammer Toes. These hammer toes are less serious because they can be diagnosed and treated while still in the developmental stage. They are called flexible hammer toes because they are still moveable at the joint. Rigid Hammer Toes. This variety is more developed and more serious than the flexible condition. Rigid hammer toes can be seen in patients with severe arthritis, for example, or in patients who wait too long to seek professional treatment. The tendons in a rigid hammer toe have become tight, and the joint misaligned and immobile, making surgery the usual course of treatment.

Causes
The muscles of each toe work in pairs. When the toe muscles get out of balance, a hammertoe can form. Muscle imbalance puts a lot of pressure on the toe's tendons and joints. This pressure forces the toe into a hammerhead shape. How do the toe muscles get out of balance? There are three main reasons. Genes. you may have inherited a tendency to develop hammertoes because your feet are somewhat unstable, they may be flat or have a high arch. Arthritis. Injury to the toe, ill-fitting shoes are the main culprits. If shoes are too tight, too short, or too pointy, they push the toes out of balance. Pointy, high-heeled shoes put particularly severe pressure on the toes.

Symptoms
Some people never have troubles with hammer toes. In fact, some people don't even know they have them. They can become uncomfortable, especially while wearing shoes. Many people who develop symptoms with hammer toes will develop corns, blisters and pain on the top of the toe, where it rubs against the shoe or between the toes, where it rubs against the adjacent toe. You can also develop calluses on the balls of the feet, as well as cramping, aching and an overall fatigue in the foot and leg.

Diagnosis
The treatment options vary with the type and severity of each hammer toe, although identifying the deformity early in its development is important to avoid surgery. Your podiatric physician will examine and X-ray the affected area and recommend a treatment plan specific to your condition.

Non Surgical Treatment
Your doctor will decide what type of hammertoe you have and rule out other medical conditions. Treatment may range from more appropriate footgear to periodic trimming and padding of the corn. Cortisone injections may be indicated if a bursitis is present. Antibiotics may be utilized in the presence of infection. Removable accommodative pads may be made for you.

Surgical Treatment
There are generally two methods surgeons use to correct hammer toes, they are joint resection (arthroplasty) or bone mending (fusion), and the location where this is performed on the toe depends on where the toe is buckled. Its important to recognize that most of the surgical work involved the joints of the toe, not the joint of the ball of the foot. Sometimes a toe relocation procedure is needed when the joint of the ball of the foot is malaligned (subluxed or dislocated).

Prevention
The best treatment is good prevention! Hammertoe can be prevented by wearing shoes with ample toe room, avoiding high heels, and wearing adjustable shoes to assure a looser fit. When buying shoes, shop at the end of the day when your feet are swollen from daily activity, try both shoes on to confirm they fit properly, and if necessary, visit a shoe repair store to see if they can stretch your shoes for a better fit.

Overview
Hammer toe is defined as a deformity in the toe where part of the toe is permanently bent downward resembling a hammer. Two related conditions are mallet toe and claw toe which effect different toe joints in slightly different ways. The key difference is that Hammer toes tends to effect the middle joint in the toe (note: not the middle toe, the middle toe joint). The disease is usually associated with the second largest toe but can effect the third or fourth toe as well. Mallet toe effects the uppermost toe joint whereas claw toe is caused by the tow being held in a cramped ?claw-like? position.

Causes
Most hammertoes are caused by wearing ill-fitting, tight or high-heeled shoes over a long period of time. Shoes that don't fit well can crowd the toes, putting pressure on the middle toes and causing them to curl downward. The condition may be more likely when the second toe is longer than the first toe or when the arch of the foot is flat. Hammertoe can also be present at birth (congenital). Hammertoe also can be caused by a bunion, which is the knobby bump that sometimes develops at the side of the big toe. A bunion causes the big toe to bend toward the other toes. The big toe can then overlap and crowd the smaller toes. Occasionally, a hammertoe is inherited or caused by arthritis in the toe joint.

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
Although hammertoes are readily apparent, to arrive at a diagnosis the foot and ankle surgeon will obtain a thorough history of your symptoms and examine your foot. During the physical examination, the doctor may attempt to reproduce your symptoms by manipulating your foot and will study the contractures of the toes. In addition, the foot and ankle surgeon may take x-rays to determine the degree of the deformities and assess any changes that may have occurred.

Non Surgical Treatment
Hammer toes usually get progressively worse over time, especially if you avoid seeking care. Not all cases are the same, so it is important to get your podiatrist or foot surgeon to evaluate your condition so that you can get the treatment you need as soon as possible. Your treatment options will vary depending on the severity of your hammer toe. You may not require surgery to treat your hammer toe. Your doctor may suggest one of these less invasive measures. Instead of wearing shoes that are too high or too short, wear comfortable shoes that have plenty of room and are flat or low-heeled. Your doctor can prescribe pads that will prevent your corns or calluses from getting irritated. Avoid over-the-counter medicated pads, as they contain acid that can worsen your condition. An orthotic device can be customized to fit your shoe and foot. It can help control your tendon and muscle imbalance, which in turn may ease your pain. NSAIDS (nonsteroidal anti-inflammatory drugs) such as ibuprofen can reduce inflammation. By relieving swelling in your toe joint, you can alleviate your pain. Splints or small straps can be placed on your toe by a foot surgeon to realign your bent toe. Applying ice packs wrapped in cloth on your hammer toe can reduce inflammation and swelling. Gently massaging your toes can assist in alleviating your pain caused by hammer toes. Try exercises that stretch your feet as these can help restore your muscle balance. A simple exercise that can help is to pick up a cloth or small object from the floor by curling your toes. This action will help your feet and toes by stretching them.

Surgical Treatment
Surgery to straighten the toe may be needed if an ulcer has formed on either the end or the top surface of the toe. Surgery sometimes involves cutting the tendons that support movement in the toe so that the toe can be straightened. Cutting the tendons, however, takes away the ability to bend the very end of the toe. Another type of surgery combines temporary insertion of a pin or rod into the toe and alteration or repair of the tendons, so that the toe is straightened. After surgery, the deformity rarely recurs.

Prevention
Be good to your feet, because they carry you. They are designed to last a lifetime, but that doesn?t mean they don?t need some love and care as well as some basic maintenance. Check your feet regularly for problems. This is especially true if you have diabetes or any other medical condition that causes poor circulation or numbness in your toes. If you do, check your feet every day so problems can be caught early on. 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 ask someone you love for a foot massage. A warm foot bath is also a good idea.

Overview

A bunion, also known as hallux valgus, is a painful deformity that develops at the base of the big toe. Bunions are caused when the big toe pushes and bends inward towards the other toes. This displaces the bones of the joint, causing it to protrude in a way that looks like a large growth. Bunions develop due to a variety of factors. Some people inherit feet that are more susceptible due to their shape and structure, having flat feet for instance. But bunions can be made worse by the wrong shoe, or by carrying extra weight or prolonged periods of standing or walking.

Causes
No single cause or set of causes for bunions has been identified, although gender-women develop them more frequently than men-and heredity play a role. In addition, the foot gradually widens with age as the ligaments that connect the bones in the forefoot become more lax. Contrary to what many people believe, ill-fitting footwear is not the cause of bunions. In fact, bunions are found in populations all over the world, including among those who never wear shoes. Shoes that are too tight can, however, contribute to the progression of the condition. Bunions are often bilateral, that is, appearing in both feet. Although bunions are usually seen in people who are middle-aged or older, there are adolescents who are diagnosed with the condition, usually the result of a congenital problem.
SymptomsNo matter what stage your bunion is in, you can be in pain. Though bunions take years to develop, you can experience pain at any stage. Some people don?t have bunion pain at all. Pain from a bunion can be severe enough to keep you from walking comfortably in normal shoes. The skin and deeper tissue around the bunion also may become swollen or inflamed.

Diagnosis
Orthopaedic surgeons diagnose bunions on the basis of physical examination and weight bearing x-rays. Two angles are assessed, the intermetatarsal angle, that is between the first and second metatarsals (the bones that lead up to the base of the toes). If this angle exceeds 9? (the angle found in the healthy foot) it is abnormal and referred to as metatarsus primus varus. the hallux valgus angle, that is, the angle of the big toe as it drifts toward the small toe. An angle that exceeds 15? is considered to be a sign of pathology.

Non Surgical Treatment
Early treatment of bunions is centered on providing symptomatic relief. Switching to a shoe with a rounder, deeper toe box and made of a softer more pliable leather will often provide immediate relief. The use of pads and cushions to reduce the pressure over the bone can also be helpful for mild bunion deformities. Functional foot orthotics, by controlling abnormal pronation, reduces the deforming forces leading to bunions in the first place. These may help reduce pain in mild bunion deformities and slow the progression of the deformity. When these conservative measures fail to provided adequate relief, surgical correction is indicated.


Surgical Treatment
There is more than one way to surgically treat a bunion. While there are some general guidelines, some procedures work well for some Surgeons and poorly for others. Your Surgeon should consider the severity of your bunion, medical condition, lifestyle, and recuperation time when considering the surgical treatment.

Overview

Your big toe is the hardest working toe. Every time your foot pushes off the ground, this toe supports most of your body's weight. Because the big toe is so critical to movement, any problem with it can make walking or even standing painful. A bunion (excess or misaligned bone in the joint) is one of the most common big-toe problems. In addition to causing pain, a bunion changes the shape of your foot, making it harder to find shoes that fit. But you don't have to hobble for the rest of your life. Bunions can be treated. With your doctor's help, your feet can feel and look better.

Causes
The main cause of bunions is excessive pressure being placed on the front of the foot, and is usually the result of wearing high-heeled shoes with pointed toes. A study by the American Orthopaedic Foot and Ankle Society found that 88 percent of women in the United States wear shoes that are too small and that 55 percent of them have bunions. Overall, bunions are nine times more common in women than men. In some cases, bunions are hereditary; they also may be caused by arthritis or polio.
SymptomsThe most obvious symptoms of a bunion are. Pain in the area of the MTP joint, the joint where your big toe connects to your foot. Bending of the big toe in towards the other toes. An enlarged bump of bone or tissue at the MTP joint. Each symptom can range in degree from small to severe. Sometimes the pain can be sufficient to make it difficult to walk in normal shoes. Other symptoms may include. Swelling and inflammation of the skin around the MTP joint. Thickening of the skin in the area of the joint. Restricted motion in your big toe. Pressure from the inward bending of your big toe can affect your other toes, leading to corns on your smaller toes. Ingrown toenails on the smaller toes. Development of hammertoes in the other toes. Calluses on the bottom of your foot. If you have any of these symptoms, especially pain, displacement of your big toe or development of a bulge, you should consider consulting your physician. Even if you're not significantly bothered by some of these symptoms, bunions tend to continue getting bigger and more serious over time and should be taken care of before they do so.

Diagnosis
Orthopaedic surgeons diagnose bunions on the basis of physical examination and weight bearing x-rays. Two angles are assessed, the intermetatarsal angle, that is between the first and second metatarsals (the bones that lead up to the base of the toes). If this angle exceeds 9? (the angle found in the healthy foot) it is abnormal and referred to as metatarsus primus varus. the hallux valgus angle, that is, the angle of the big toe as it drifts toward the small toe. An angle that exceeds 15? is considered to be a sign of pathology.

Non Surgical Treatment
Getting rid of a Bunion is almost impossible without surgery. Foot and toe exercises can help. Foam pads can reduce the pressure on the joint. Ice packs and anti-inflammatory medication can help reduce swelling. The progress of a Bunion can be slowed or even halted, especially if it is caused by ill-fitting footwear. Of course the best course of action is to not wear pointy-toed high-heel shoes to begin with. But if you have worn improper footwear and now want to stop the progress of Bunions.


Surgical Treatment
If conservative treatment doesn't provide relief, you may need surgery. A number of surgical procedures are performed for bunions, and no particular surgery is best for every problem. Knowing what caused your bunion is essential for choosing the best procedure to ensure correction without recurrence. Most surgical procedures include rmoving the swollen tissue from around your big toe joint Straightening your big toe by removing part of the bone Permanently joining the bones of your affected joint You may be able to walk on your foot immediately after some bunion procedures. With other procedures, it may be a few weeks or longer. To prevent a recurrence, you'll need to wear proper shoes after recovery.

Overview

Achilles tendon rupture are common. Most athletes describe a sudden acute event with an associated popping sensation and pain in the Achilles tendon. They often think that they have been kicked or struck in the calf. It is important to get prompt treatment and to be placed in an equinous cast (a cast with the foot in a pointed position). More definitive treatment options can be discussed after this has occurred.

Causes
Inflammation/strain of the tendon is usually caused by overuse, for example, frequent jumping in volleyball, netball or basketball. It is often also caused by a sudden increase in certain types of training, such as hill sprinting or track running, particularly when running in spikes. Tendinopathy can also be associated with ageing. Our ability to regenerate damaged tissue decreases as we age and the quality of the tendon deteriorates. However, the better news is that sensible training can actually strengthen all our soft tissue (tendons, ligaments and muscle). Tightness in the calf muscles will demand greater flexibility of the tendon, which inevitably results in overuse and injury. Biomechanically, the tightness can reduce the range of dorsiflexion (toe up position) in the ankle, which increases the amount and duration of pronation. This problem is known as overpronation.* This reduces the ability of the foot to become a rigid lever at push off and places more lateral and linear forces through the tendon. This imbalance can translate into altered rotation of the tibia (shin bone) at the knee joint and, in turn, produce compensatory rotation at the hip joint with subsequent injuries to the shin, knee and hip. Pronation is part of the natural movement of the subtalar joint in the foot. It allows ?eversion? (turning the sole outwards), dorsiflexion and abduction (pointing the toes out to the side). Pronation is a normal part of the gait cycle, when walking and running, and it helps to provide shock absorption in the foot. When pronation is excessive, the foot has a tendency to roll inward more than normally acceptable. One sign of overpronation is greater wear on the inside of your running shoes than on the midsole. Lack of stability around the ankle joint can also be a contributory factor, as recurrent ankle sprains appear to be associated with a high incidence of Achilles tendonopathy. Wearing shoes that don?t fit or support the foot properly can be a major contributing cause of Achilles tendon injury.

Symptoms
It is important to know that pain at the back of the heel is not always due to Achilles tendon rupture. It may be due to bursitis (fluid accumulation in the heel due to repeated irritation) and tendonitis (pain along the Achilles tendon due to constant friction and irritation). The above disorders tend to improve with use of pain medications and rest, whereas Achilles tendon rupture requires surgery and/or a cast.

Diagnosis
A staggering 20%-30% of Achilles tendon ruptures are missed. Thompson (calf squeeze) test is 96% sensitive and 93% sensitive. Unfortunately, some health practitioners fail to perform this simple clinical test. Ultrasound examination or an MRI can confirm an Achilles tendon rupture.

Non Surgical Treatment
A physical therapist teaches you exercises to help improve movement and strength, and to decrease pain. Use support devices as directed. You may need crutches or a cane for support when you walk. These devices help decrease stress and pressure on your tendon. Your caregiver will tell you how much weight you can put on your leg. Ask for more information about how to use crutches or a cane correctly. Start activity as directed. Your caregiver will tell you when it is okay to walk and play sports. You may not be able to play sports for 6 months or longer. Ask when you can go back to work or school. Do not drive until your caregiver says it is okay.


Surgical Treatment
Surgery is a common treatment for a complete rupture of the Achilles tendon. The procedure generally involves making an incision in the back of your lower leg and stitching the torn tendon together. Depending on the condition of the torn tissue, the repair may be reinforced with other tendons. Surgical complications can include infection and nerve damage. Infection rates are reduced in surgeries that employ smaller incisions. After treatment, whether surgical or nonsurgical, you'll go through a rehabilitation program involving physical therapy exercises to strengthen your leg muscles and Achilles tendon. Most people return to their former level of activity within four to six months.

Prevention
Prevention centers on appropriate daily Achilles stretching and pre-activity warm-up. Maintain a continuous level of activity in your sport or work up gradually to full participation if you have been out of the sport for a period of time. Good overall muscle conditioning helps maintain a healthy tendon.

Overview
Often considered solely a product of genetics, flatfoot rarely carries with it the stigma of presenting over time. The truth, however, is that flatfoot does not discriminate on the basis of age and can become an issue in the form of adult-acquired flatfoot. Like its congenital cousin, adult-acquired flatfoot deformity is one that, in causing structural damage to the foot (and particularly to the posterior tibial tendon), creates an imbalance that may result in any number of symptoms, including inflammation, pain, stiffness, limited mobility, and even arthritis.


Causes
As the name suggests, adult-acquired flatfoot occurs once musculoskeletal maturity is reached, and it can present for a number of reasons, though one stands out among the others. While fractures, dislocations, tendon lacerations, and other such traumatic events do contribute to adult-acquired flatfoot as a significant lower extremity disorder, as mentioned above, damage to the posterior tibial tendon is most often at the heart of adult-acquired flatfoot. One study further elaborates on the matter by concluding that ?60% of patients [presenting with posterior tibial tendon damage and adult-acquired flatfoot] were obese or had diabetes mellitus, hypertension, previous surgery or trauma to the medial foot, or treatment with steroids?.

Symptoms
Symptoms shift around a bit, depending on what stage of PTTD you?re in. For instance, you?re likely to start off with tendonitis, or inflammation of the posterior tibial tendon. This will make the area around the inside of your ankle and possibly into your arch swollen, reddened, warm to the touch, and painful. Inflammation may actually last throughout the stages of PTTD. The ankle will also begin to roll towards the inside of the foot (pronate), your heel may tilt, and you may experience some pain in your leg (e.g. shin splints). As the condition progresses, the toes and foot begin to turn outward, so that when you look at your foot from the back (or have a friend look for you, because-hey-that can be kind of a difficult
maneuver to pull off) more toes than usual will be visible on the outside (i.e. the side with the pinky toe). At this stage, the foot?s still going to be flexible, although it will likely have flattened somewhat due to the lack of support from the posterior tibial tendon. You may also find it difficult to stand on your toes. Finally, you may reach a stage in which your feet are inflexibly flat. At this point, you may experience pain below your ankle on the outside of your foot, and you might even develop arthritis in the ankle.

Diagnosis
Clinicians need to recognize the early stage of this syndrome which includes pain, swelling, tendonitis and disability. The musculoskeletal portion of the clinical exam can help determine the stage of the disease. It is important to palpate the posterior tibial tendon and test its muscle strength. This is tested by asking patient to plantarflex and invert the foot. Joint range of motion is should be assessed as well. Stiffness of the joints may indicate longstanding disease causing a rigid deformity. A weightbearing examination should be performed as well. A complete absence of the medial longitudinal arch is often seen. In later stages the head of the talus bone projects outward to the point of a large "lump" in the arch. Observing the patient's feet from behind shows a significant valgus rotation of the heel. From behind, the "too many toes" sign may be seen as well. This is when there is abducution of the forefoot in the transverse plane allowing the toes to be seen from behind. Dysfunction of the posterior tibial tendon can be assessed by asking the patient to stand on his/her toes on the affected foot. If they are unable to, this indicates the disease is in a more advanced stage with the tendon possibly completely ruptured.

Non surgical Treatment
A painless flatfoot that does not hinder your ability to walk or wear shoes requires no special treatment or orthotic device. Other treatment options depend on the cause and progression of the flatfoot. Conservative treatment options include making shoe modifications. Using orthotic devices such as arch supports and custom-made orthoses. Taking nonsteroidal anti-inflammatory drugs such as ibuprofen to relieve pain. Using a short-leg walking cast or wearing a brace. Injecting a corticosteroid into the joint to relieve pain. Rest and ice. Physical therapy. In some cases, surgery may be needed to correct the problem. Surgical procedures can help reduce pain and improve bone alignment.


Surgical Treatment
Surgical intervention for adult acquired flatfoot is appropriate when there is pain and swelling, and the patient notices that one foot looks different than the other because the arch is collapsing. As many as three in four adults with flat feet eventually need surgery, and it?s better to have the joint preservation procedure done before your arch totally collapses. In most cases, early and appropriate surgical treatment is successful in stabilizing the condition.
