Hallux abductovalgus (HAV) or bunion, is a commonly seen deformity of the first metatarsophalangeal joint (MPJ) in which the hallux is abducted and everted, frequently overriding the second toe. Although the terms HAV and bunion are often used synonymously (as is done in this paper), it should be noted that a bunion actually refers to the callus and inflamed adventitious bursa overlying the HAV deformity. Even though bunions have been described in the medical literature for several hundred years (the word bunion is believed to be derived from the Latin, bunio, meaning turnip), there continues to be much controversy concerning its etiology. This is most likely because the development of HAV is multifactorial, stemming from a variety of structural and functional aberrancies.
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.
SymptomsJust because you have a bunion does not mean you will necessarily have pain. There are some people with very severe bunions and no pain and people with mild bunions and a lot of pain. Symptoms for a bunion may include pain on the inside of your foot at the big toe joint, swelling on the inside of your foot at the big toe joint, appearance of a "bump" on the inside edge of your foot. The big toe rolling over to one side. Redness on the inside of your foot at the big toe joint. Numbness or burning in the big toe (hallux). Decreased motion at the big toe joint. Painful bursa (fluid-filled sac) on the inside of your foot at the big toe joint. Pain while wearing shoes - especially shoes too narrow or with high heels. Joint pain during activities. Other conditions which may appear with bunions include Corns in between the big toe and second toe. Callous formation on the side or bottom of the big toe or big toe joint. Callous under the second toe joint. Pain in the second toe joint.
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
Apply special pads and dressings to protect the bunion from shoe pressure. Inject steroid and local anesthetic around the bunion to reduce inflammation. This is especially useful if there is an associated bursitis. Recommend commercially available or custom made shoes. Prescribe functional orthotics to correct faulty foot function, and help prevent worsening of the deformity. Recommend bunion surgery to correct the deformity.
There are dozens and dozens of types of surgery designed to address bunion deformities, and each have different indications. But in short, some procedures simply address an enlarged bump. Some simply address a crooked big toe. But in order to slow the return of the bunion deformity, most procedures aim to realign the big toe with the bone behind it, the "first metatarsal." This would also realign the joint surfaces between those two bones. But even if the surgery is designed to realign the big toe, there are still many choices to consider. Some procedures are meant for a short first metatarsal and others for a long first metatarsal. Some are best when the foot is very unstable, others are based on the severity of the arthritis present. In fact, there are many, many factors to consider when designing a procedure to address a particular patient's foot, to the extent that what's involved in a bunion surgery not only varies from patient to patient--the procedures often vary even from a patient's right foot to the left foot.

The common bunion is a localized area of enlargement of the inner portion of the joint at the base of the big toe. The enlargement actually represents a misalignment of the big toe joint (metatarsal phalangeal joint) and, in some cases, additional bone formation. The misalignment causes the big toe to point outward (medically termed hallux valgus deformity) toward the smaller toes. This deformity is progressive and will increase with time. The enlarged joint at the base of the big toe (the first metatarsophalangeal joint, or MTP joint) can become inflamed with redness, tenderness, and pain. A small fluid-filled sac (bursa) adjacent to the joint can also become inflamed (bursitis), leading to additional swelling, redness, and pain. A more deep joint pain may occur as localized arthritis develops in later stages of the deformity. A less common bunion is located at the joint at the base of the smallest (fifth) toe. This bunion is sometimes referred to as a tailor's bunion or bunionette.
Bunions develop when the pressures of bearing and shifting your weight fall unevenly on the joints and tendons in your feet. This imbalance in pressure makes your big toe joint unstable, eventually molding the parts of the joint into a hard knob that juts out beyond the normal shape of your foot. Experts disagree on whether tight, high-heeled or too-narrow shoes cause bunions or whether footwear simply contributes to bunion development. Other causes include inherited foot type, foot injuries, deformities present at birth (congenital). Bunions may be associated with certain types of arthritis, particularly inflammatory types, such as rheumatoid arthritis. An occupation that puts extra stress on your feet or one that requires you to wear pointed shoes also can be a cause.
SymptomsYour bunion may not cause any symptoms. Or you may have pain in your big toe, red or irritated skin over the bunion, and swelling at the base of the big toe. The big toe may point toward the other toes and cause problems in other toes, such as hammer toe . A bunionette can cause similar symptoms at the base of the little toe.
Clinical findings are usually specific. Acute circumferential intense pain, warmth, swelling, and redness suggest gouty arthritis (see Gout) or infectious arthritis (see Acute Infectious Arthritis), sometimes mandating examination of synovial fluid. If multiple joints are affected, gout or another systemic rheumatic disease should be considered. If clinical diagnosis of osteoarthritic synovitis is equivocal, x-rays are taken. Suggestive findings include joint space narrowing and bony spurs extending from the metatarsal head or sometimes from the base of the proximal phalanx. Periarticular erosions (Martel sign) seen on imaging studies suggest gout.
Non Surgical Treatment
Apply a commercial bunion pad around the bony prominence, use only non-medicated pads. Wear shoes with a wide and deep toe box. You should be able to "dimple" the leather over your bunion. Avoid all high heeled shoes. If your bunion becomes painful red, and swollen try elevating your foot and applying ice for about 20 minuets every hour. If symptoms persist, consult your podiatrist or physician.
Procedures can range from shaving off excess bone to restructuring and fusing the big toe. For mild conditions, you may simply need the connective tissues holding your big toe to be tightened so they hold the digit in the correct position. More advanced bunions will need more manipulation and involved remedies. Cuts in the bone tissue can help our specialists realign the toe. You may need to have the damaged portion of the joint removed. In severe cases, the joint may be fused to prevent it from moving out of position again. If your bunion created other foot complications, like hammertoes, our specialists may correct those during the procedure as well.

Flat feet is the most common foot deformity known. In fact, sixty million Americans or 25% of the U.S. population have flat feet. Some of these people may experience problems that limit their activities, while others can run marathons or play in the NBA.
The most common cause of arch pain is plantar fasciitis. Plantar fasciitis is inflammation of the fibrous band of tissue that connects the heel to the toes. Sufferers of plantar fasciitis typically feel pain early in the morning when they first get out of bed. Another common cause of arch pain is fallen arches or flat feet. Fallen arches result in the sole of the foot becoming flat so that the entire sole of the foot touches the ground. Fallen arches can lead to pain in the ankles, knees, feet, and even in the legs. While fallen arches are often inherited, for some it develops as a result of wear and tear on your feet. Wearing shoes without proper metatarsal support, or arch support, can overstretch the tendon that supports the arch causing the arch to flatten out.
The foot of a newborn with congenital vertical talus typically has a convex rocker-bottom shape. This is sometimes combined with an actual fold in the middle of the foot. The rare person who is diagnosed at an older age often has a "peg-leg" gait, poor balance and heavy calluses on the soles where the arch would normally be. If a child with congenital vertical talus has a genetic disorder, additional symptoms often are seen in other parts of the body.
In more difficult cases of plantar fasciitis you should see your foot health professional for a thorough examination. They will find out why your arch or heel pain occurred in the first place and devise a treatment plan to relieve your pain and prevent it from reoccurring. They will evaluate your feet, walking pattern (gait), shoes, activities, exercise methods, and other relevant information and then devise your treatment plan.

Treatment for these injuries varies depending on the severity of the injury. Most strains and sprains can be treated with rest, ice, compression and elevation (RICE). Moderate to severe cases, however, may require some form of immobilization such as a brace or a cast. Certain injuries that don't heal within the expected time frame may require surgery. It is important to seek medical attention as soon as possible for foot and ankle injuries, especially if it is causing you to limp or there is swelling. Prompt and appropriate treatment and rehabilitation ensures the best possible recovery.
There are two types of bone procedure for flat feet, those where bone cuts and bone grafts are used to alter the alignment by avoiding any joint structures, or joint invasive procedures (called fusions or arthrodeses) that remove a joint to reshape the foot. With joint fusion procedures, there are those procedures that involve non-essential joints of the foot versus those that involve essential joints. All bone procedures have their place in flat foot surgery, and Dr. Blitz carefully evaluates each foot to preserve as much motion and function while obtaining proper and adequate alignment. In many cases a flat foot reconstruction involves both soft tissue procedures and bone procedures to rebuild and restore the arch. There are several joints in the arch of the foot that can collapse - and these joints are non-essential joints of the foot. This does not mean that they do not have a purpose, but rather become inefficient is providing a stable platform for function. As such, locking these non-essential non-functioning joints into place is commonly recommended. These joints are fused together with screws and/or plates. A heel bone that is no longer in proper position and pushed outwards away from the foot can be corrected with a bone cut and realignment procedure, so long as the displacement is not too significant. A benefit of this surgery is that it keeps the back portion of the foot mobile, and helps the surrounding tendons work for efficiently in maintaining the arch. In certain flat feet, the foot is deviated outwards and away from the midline of the body. Sometimes, this is due to the outer portion of the foot being shorter than the inner portion. Here bone graft can be added to the outer edge of the foot to lengthen the foot to swing the foot over into a corrected position. This procedure is most commonly performed in children and young adults. A bone graft is inserted into the top part of the arch to realign a component of the flat foot, medically known as forefoot varus or medial column elevatus. The back part of the foot (called the rearfoot complex) can be the cause (or source) of the flat foot or the simply affected by the flat foot foot. In simple terms, the back part of the foot can be made to flatten out due to arch problems - and vica versa for that matter. Dr. Blitz specifically identifies the cause of the flat foot as this will determine the best treatment plan, as each flat foot needs to be evaluated individually. The rearfoot is made up of three joints, and depending on the extent and most importantly the rigidity of these joints, they may require fusion to restore alignment. When all three joints require fusion - this call is a triple arthrodesis. For completeness, isolated fusion of any of the three joints can be performed (such as subtalar joint arthrodesis, talonavicular arthrodesis, and calcaneaocuboid joint arthrodesis). The medical decision making for isolated fusions is beyond the scope this article, but Dr. Blitz tries to avoid any rearfoot fusion for flexible feet because these are joints are essential joints of the foot, especially in younger people. Those in severe cases, it may be advantageous to provide re-alignment.
The best method for preventing plantar fasciitis is stretching. The plantar fascia can be stretched by grabbing the toes, pulling the foot upward and holding for 15 seconds. To stretch the calf muscles, place hands on a wall and drop affected leg back into a lunge step while keeping the heel of the back leg down. Keep the back knee straight for one stretch and then bend the knee slightly to stretch a deeper muscle in the calf. Hold stretch for 15 seconds and repeat three times.
