The term bunion as it is popularly used describes a variety of deformities involving a painful prominence and swelling at the base of the big toe. Orthopaedists use additional terms to describe the different deformities. The condition in which the big toe deviates from the normal position toward the direction of the second toe is referred to as hallux valgus. The word bunion refers specifically to the prominence made of bone and at times an inflamed bursa. This bursa develops on the first metatarsal head at the base of the big toe because of this bony prominence. Although a bunion may develop without hallux valgus, for the purposes of this discussion, the term bunion will include both. Dorsal bunions, are a separate entity, in which the prominence appears on the top of the base of the toe-often the result of an arthritic joint.

Causes
The main cause of bunions is a mechanical imbalance in the feet which is usually inherited. The mechanical imbalance is known as overpronation, where the feet roll in towards the arch and big toe. This added weight and stress transfer towards the big toe, causes instability in the structures of this area and a bunion develops.

Symptoms
With Bunions, a person will have inflammation, swelling, and soreness on the side surface of the big toe. Corns most commonly are tender cone-shaped patches of dry skin on the top or side of the toes. Calluses will appear on high-pressure points of the foot as thick hardened patches of skin.

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
Before treatment of a painful bunion can begin, medical evaluation is needed. There are a number of other causes of pain in the big toe such as osteoarthritis, rheumatoid arthritis, infection and gout. Circulatory problems not only cause pain, but may also cause serious complications if surgery is attempted. Diabetes and cigarette smoking may diminish healing potential and increase the risk of infection.

Surgical Treatment
Conservative bunion treatment methods help to reduce the symptoms but they cannot undo changes in the bone to fully correct the condition. If the pain becomes severe and it starts to affect your daily life, then foot bunion surgery may be the best option to correct a hallux abducto valgus. There are a number of different surgical options, depending on the severity of the bony deformity. The two most common types of surgery are Osteotomy. This is the most common type pf surgery and involves removing part of the bony lump and realigning the toes. It is also known as a bunionectomy or exostectomy. The ligaments around the big toe may also need realigning and this will be done at the same time if necessary. Fusion.This is where the joint at the base of the big toe (metatarsophalangeal joint) is fused together, known as an arthrodesis. This is only indicated in severe cases or if other treatments have failed as it severely limits the movement of the big toe.

Prevention
The best way to reduce your chances of developing bunions is to wear shoes that fit properly. Shoes that are too tight or have high heels can force your toes together. Bunions are rare in populations that don?t wear shoes. Make sure your shoes are the correct size and that there's enough room to move your toes freely. It's best to avoid wearing shoes with high heels or pointy toes. ]]> https://ameblo.jp/latonyaleider/entry-12040332453.html Thu, 18 Jun 2015 14:50:05 +0900 Overview
Even though bunions are a common foot condition, they are probably the one with the most misconceptions. Many people suffer unnecessarily with the pain and/or appearance of bunions for years before seeking treatment out of fear about ?surgery?. The good news is that most bunion pain can be resolved without surgery.

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.

Symptoms
Bunions may cause no pain at first. But as the big toe begins to turn in towards the other toes, people with bunions usually experience redness, pain, swelling, and tenderness in the area around the joint. Pressure inside the joint or from footwear pressing against the bunion may also cause discomfort. As the affected toe curves closer to the other toes on the foot, these toes can become painful as well. Complications of bunions include corns, calluses, hammer toe, and ingrown toenails. Other complications include irritation of the nerves surrounding the bunion area. Excess rubbing of the bunion against the footwear may lead to changes in the skin, resulting in corns or calluses. Hammer toe is a deformity of the toe immediately next to the big toe. A hammer toe is slightly raised and points upwards from the base and downwards at the end of the toe. Ingrown toenails can result from increased pressure from the big toe on the other toes. There may also be a decrease in the amount a person can move the joint affected by the bunion. Irritation of the nerves will feel like burning or decreased sensation.

Diagnosis
The doctor considers a bunion as a possible diagnosis when noting the symptoms described above. The anatomy of the foot, including joint and foot function, is assessed during the examination. Radiographs (X-ray films) of the foot can be helpful to determine the integrity of the joints of the foot and to screen for underlying conditions, such as arthritis or gout. X-ray films are an excellent method of calculating the alignment of the toes when taken in a standing position.

Non Surgical Treatment
Treatment options vary with the type and severity of each bunion, although identifying the deformity early in its development is important in avoiding surgery. The primary goal of most early treatment options is to relieve pressure on the bunion and halt the progression of the joint deformity. A podiatrist may recommend these treatments. Padding and Taping, Often the first step in a treatment plan, padding the bunion minimizes pain and allows the patient to continue a normal, active life. Taping helps keep the foot in a normal position, thus reducing stress and pain. Medication, Anti-inflammatory drugs and cortisone injections are often prescribed to ease the acute pain and inflammation caused by joint deformities. Physical Therapy, Often used to provide relief of the inflammation and bunion pain. Ultrasound therapy is a popular technique for treating bunions and their associated soft tissue involvement. Orthotics, Shoe inserts may be useful in controlling foot function and may reduce symptoms and prevent worsening of the deformity.

Surgical Treatment
Bunion surgery is occasionally required when the bunion deformity is too advanced for conservative treatment to work. Your surgeon will usually cut an angular section from the bone to correct the alignment. In some cases, multiple toes may need to be straighten.

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. ]]> https://ameblo.jp/latonyaleider/entry-12035433385.html Fri, 05 Jun 2015 21:41:56 +0900 Overview
Arch pain is common in people with a typical structural problem known as flat feet. Arch pain may also occur in people with fallen arches (a fallen arch is one that has collapsed due to bearing weight). Flat feet can lead to extreme stress or inflammation of the plantar fascia, possibly causing severe discomfort and leading to other foot problems. Without properly supported arches, simple movement can pull your body out of alignment and cause stress, strain and fatigue to your lower body.

Causes
The causes of high arched feet can vary greatly. They range from neurological disorders, club foot, injury, and often times there may be no known reason. The idea behind surgery to correct this often painful condition is to bring the arch down and thereby, allow the ground pressure of walking to be more evenly distributed across the entire bottom of the foot. Over time high arch feet can cause severe plantar calluses, ulcerations broken metatarsals and even chronically sprained ankles.

Symptoms
Bones and ligaments work together to form joints, and bones are joined together by ligaments. Strains occur in ligaments. In the arch, there are ligaments that are located at the ends of each bone. These ligaments connect the bones to other bones on both ends and on the sides. Point tenderness and looseness of a joint are indicators of a sprain. Fractures are indicated by point tenderness that may be severe over the area of bone that is affected. There may be a distinguishable lump or gap at the site of the fracture. A rotated toe or forefoot may also be a sign of a fracture.

Diagnosis
Magnetic Resonance Imaging (MRI) can show tendon injury and inflammation but cannot be relied on with 100% accuracy and confidence. The technique and skill of the radiologist in properly positioning the foot with the MRI beam are critical in demonstrating the sometimes obscure findings of tendon injury around the ankle. Magnetic Resonance Imaging (MRI) is expensive and is not necessary in most cases to diagnose posterior tibial tendon injury. Ultrasound has also been used in some cases to diagnose tendon injury, but this test again is usually not required to make the initial diagnosis.

Non Surgical Treatment
High arches that are flexible do not require any treatment. In cases where there is pain, shoe modifications such as an arch insert or support insole can help to relieve pain during walking. Custom orthotic devices can be given that fit into the shoe and provide stability and cushioning effect. Your doctor may recommend a brace to help keep the foot and ankle stable. In severe cases, surgery is performed to flatten the foot. Any coexisting nerve disorders are also treated.

Surgical Treatment
If you have pain that has not been responsive to other treatments, there is a new non-surgical treatment that was recently approved by the FDA. ESWT (extracorporeal shockwave therapy) uses strong electrohydraulic acoustic (sound) energy that triggers the body?s natural repair mechanism. This treatment method is safe, effective and requires a very short recovery period compared to older surgical techniques.

Prevention
Drink plenty of water before, during and after your workout. Dehydration is a common cause of muscle cramps, according to MayoClinic.com. If your workouts are long and strenuous, drink a carbohydrate-based electrolyte beverage too. Warm up the muscles of your feet before you work out. A simple exercise is to write the letters of the alphabet with your toes. Perform the warm up with bare feet and exaggerate the movements to challenge your muscles. Wear properly fitted shoes. Visit a sporting goods store and get your feet and arches measured. Ask for help selecting a pair of shoes to fit your workout. For instance, if you play soccer, you need cleats, not running shoes. Take a break. Cramps can be your body's way of telling you you're exercising too much, according to MayoClinic.com. Rest for a few days, then resume exercise and see if you can complete a workout without arch cramps. Stretch. At the end of your workout, perform a few stretching exercises to keep your muscles from tightening and cramping. Sit down, lean over and grasp your toes. Pull the toes toward your body until you feel tension in the arch of your foot. Hold the stretch for 20 to 30 seconds, then repeat on the opposite side. Another easy way to stretch your arch is to put a towel on the floor, curl your toes around it and pull it toward your body.

Stretching Exercises
People with flexible feet who develop fallen arches may benefit from foot strengthening exercises, notes the Nicholas Institute of Sports Medicine and Athletic Trauma. Standing on a towel in bare feet and grasping the material with the toes is an easy foot-strengthening exercise that can be done at home. Standing on one leg while arching and releasing the foot may also prove useful. Doctors may prescribe gentle stretching exercises for the foot and ankle tendons. ]]> https://ameblo.jp/latonyaleider/entry-12034082311.html Tue, 02 Jun 2015 14:00:38 +0900 Overview
There are four stages of posterior tibial tendon dysfunction. In the first stage the posterior tibial tendon is inflamed but has normal strength. There is little to no change in the arch of the foot. In stage two the tendon is partially torn or shows degenerative changes and as a result loses strength. There is considerable flattening of the arch without arthritic changes in the foot. Stage three results when the posterior tibial tendon is torn and not functioning. As a result the arch is completely collapsed with arthritic changes in the foot. Stage four is identical to stage three except that the ankle joint also becomes arthritic.

Causes
The posterior tibial tendon, which connects the bones inside the foot to the calf, is responsible for supporting the foot during movement and holding up the arch. Gradual stretching and tearing of the posterior tibial tendon can cause failure of the ligaments in the arch. Without support, the bones in the feet fall out of normal position, rolling the foot inward. The foot's arch will collapse completely over time, resulting in adult acquired flatfoot. The ligaments and tendons holding up the arch can lose elasticity and strength as a result of aging. Obesity, diabetes, and hypertension can increase the risk of developing this condition. Adult acquired flatfoot is seen more often in women than in men and in those 40 or older.

Symptoms
PTTD begins with a gradual stretching and loss of strength of the posterior tibial tendon which is the most important tendon supporting the arch of the human foot. Left untreated, this tendon will continue to lengthen and eventually rupture, leading to a progressive visible collapse of the arch of the foot. In the early stages, patients with PTTD will notice a pain and swelling along the inner ankle and arch. Many times, they are diagnosed with ?tendonitis? of the inner ankle. If the foot and ankle are not properly supported during this early phase, the posterior tibial tendon can rupture and devastating consequences will occur to the foot and ankle structure. The progressive adult acquired flatfoot deformity will cause the heel to roll inward in a ?valgus? or pronated direction while the forefoot will rotate outward causing a ?duckfooted? walking pattern. Eventually, significant arthritis can occur in the joints of the foot, the ankle and even the knee. Early diagnosis and treatment is critical so if you have noticed that one, or both, of your feet has become flatter in recent times come in and have it checked out.

Diagnosis
The adult acquired flatfoot, secondary to posterior tibial tendon dysfunction, is diagnosed in a number of ways with no single test proven to be totally reliable. The most accurate diagnosis is made by a skilled clinician utilizing observation and hands on evaluation of the foot and ankle. Observation of the foot in a walking examination is most reliable. The affected foot appears more pronated and deformed compared to the unaffected foot. Muscle testing will show a strength deficit. An easy test to perform in the office is the single foot raise. A patient is asked to step with full body weight on the symptomatic foot, keeping the unaffected foot off the ground. The patient is then instructed to "raise up on the tip toes" of the affected foot. If the posterior tibial tendon has been attenuated or ruptured, the patient will be unable to lift the heel off the floor and rise onto the toes. In less severe cases, the patient will be able to rise on the toes, but the heel will not be noted to invert as it normally does when we rise onto the toes. X-rays can be helpful but are not diagnostic of the adult acquired flatfoot. Both feet - the symptomatic and asymptomatic - will demonstrate a flatfoot deformity on x-ray. Careful observation may show a greater severity of deformity on the affected side.

Non surgical Treatment
Conservative (nonoperative) care is advised at first. A simple modification to your shoe may be all that???s needed. Sometimes purchasing shoes with a good arch support is sufficient. For other patients, an off-the-shelf (prefabricated) shoe insert works well. The orthotic is designed specifically to position your foot in good alignment. Like the shoe insert, the orthotic fits inside the shoe. These work well for mild deformity or symptoms. Over-the-counter pain relievers or antiinflammatory drugs such as ibuprofen may be helpful. If symptoms are very severe, a removable boot or cast may be used to rest, support, and stabilize the foot and ankle while still allowing function. Patients with longer duration of symptoms or greater deformity may need a customized brace. The brace provides support and limits ankle motion. After several months, the brace is replaced with a foot orthotic. A physical therapy program of exercise to stretch and strengthen the foot and leg muscles is important. The therapist will also show you how to improve motor control and proprioception (joint sense of position). These added features help prevent and reduce injuries.

Surgical Treatment
In cases where cast immobilization, orthoses and shoe therapy have failed, surgery is the next alternative. The goal of surgery and non-surgical treatment is to eliminate pain, stop progression of the deformity and improve mobility of the patient. Opinions vary as to the best surgical treatment for adult acquired flatfoot. Procedures commonly used to correct the condition include tendon debridement, tendon transfers, osteotomies (cutting and repositioning of bone) and joint fusions. (See surgical correction of adult acquired flatfoot). Patients with adult acquired flatfoot are advised to discuss thoroughly the benefits vs. risks of all surgical options. Most procedures have long-term recovery mandating that the correct procedure be utilized to give the best long-term benefit. Most flatfoot surgical procedures require six to twelve weeks of cast immobilization. Joint fusion procedures require eight weeks of non-weightbearing on the operated foot - meaning you will be on crutches for two months. The bottom line is, Make sure all of your non-surgical options have been covered before considering surgery. Your primary goals with any treatment are to eliminate pain and improve mobility. In many cases, with the properly designed foot orthosis or ankle brace, these goals can be achieved without surgical intervention. ]]> https://ameblo.jp/latonyaleider/entry-12018300434.html Fri, 24 Apr 2015 17:43:50 +0900
