Acquired Flat Foot Tibialis Posterior

posted on 16 Apr 2015 13:51 by tanbudget8504
Overview
Adult acquired flatfoot deformity (AAFD), embraces a wide spectrum of deformities. AAFD is a complex pathology consisting both of posterior tibial tendon insufficiency and failure of the capsular and ligamentous structures of the foot. Each patient presents with characteristic deformities across the involved joints, requiring individualized treatment. Early stages may respond well to aggressive conservative management, yet more severe AAFD necessitates prompt surgical therapy to halt the progression of the disease to stages requiring more complex procedures. We present the most current diagnostic and therapeutic approaches to AAFD, based on the most pertinent literature and our own experience and investigations. Acquired Flat Feet

Causes
As discussed above, many health conditions can create a painful flatfoot. Damage to the posterior tibial tendon is the most common cause of AAFD. The posterior tibial tendon is one of the most important tendons of the leg. It starts at a muscle in the calf, travels down the inside of the lower leg and attaches to the bones on the inside of the foot. The main function of this tendon is to hold up the arch and support your foot when you walk. If the tendon becomes inflamed or torn, the arch will slowly collapse. Women and people over 40 are more likely to develop problems with the posterior tibial tendon. Other risk factors include obesity, diabetes, and hypertension. Having flat feet since childhood increases the risk of developing a tear in the posterior tibial tendon. In addition, people who are involved in high impact sports, such as basketball, tennis, or soccer, may have tears of the tendon from repetitive use. Inflammatory arthritis, such as rheumatoid arthritis, can cause a painful flatfoot. This type of arthritis attacks not only the cartilage in the joints, but also the ligaments that support the foot. Inflammatory arthritis not only causes pain, but also causes the foot to change shape and become flat. The arthritis can affect the back of the foot or the middle of foot, both of which can result in a fallen arch.

Symptoms
Patients often experience pain and/or deformity at the ankle or hindfoot. When the posterior tibial tendon does not work properly, a number of changes can occur to the foot and ankle. In the earlier stages, symptoms often include pain and tenderness along the posterior tibial tendon behind the inside of the ankle. As the tendon progressively fails, deformity of the foot and ankle may occur. This deformity can include progressive flattening of the arch, shifting of the heel so that it no longer is aligned underneath the rest of the leg, rotation and deformity of the forefoot, tightening of the heel cord, development of arthritis, and deformity of the ankle joint. At certain stages of this disorder, pain may shift from the inside to the outside aspect of the ankle as the heel shifts outward and structures are pinched laterally.

Diagnosis
Diagnostic testing is often used to diagnose the condition and help determine the stage of the disease. The most common test done in the office setting are weightbearing X-rays of the foot and ankle. These assess joint alignment and osteoarthritis. If tendon tearing or rupture is suspected, the gold standard test would be MRI. The MRI is used to check the tendon, surrounding ligament structures and the midfoot and hindfoot joints. An MRI is essential if surgery is being considered.

Non surgical Treatment
The adult acquired flatfoot is best treated early. Accurate assessment by your doctor will determine which treatment is suitable for you. Reduce your level of activity and follow the RICE regime. R - rest as often as you are able. Refrain from activity that will worsen your condition, such as sports and walking. I - ice, apply to the affected area, ensure you protect the area from frostbite by applying a towel over the foot before using the ice pack. C - compression, a Tubigrip or elasticated support bandage may be applied to relieve symptoms and ease pain and discomfort. E - elevate the affected foot to reduce painful swelling. You will be prescribed pain relief in the form of non-steroidal antiinflammatory medications (if you do not suffer with allergies or are asthmatic). Immobilisation of your affected foot - this will involve you having a below the knee cast for four to eight weeks. In certain circumstances it is possible for you to have a removable boot instead of a cast. A member of the foot and ankle team will advise as to whether this option is suitable for you. Footwear is important - it is advisable to wear flat sturdy lace-up shoes, for example, trainers or boots. This will not only support your foot, but will also accommodate orthoses (shoe inserts). Flat Feet

Surgical Treatment
Surgical correction is dependent on the severity of symptoms and the stage of deformity. The goals of surgery are to create a more functional and stable foot. There are multiple procedures available to the surgeon and it may take several to correct a flatfoot deformity. Usually surgical treatment begins with removal of inflammatory tissue and repair of the posterior tibial tendon. A tendon transfer is performed if the posterior tibial muscle is weak or the tendon is badly damaged. The most commonly used tendon is the flexor digitorum longus tendon. This tendon flexes or moves the lesser toes downward. The flexor digitorum longus tendon is utilized due to its close proximity to the posterior tibial tendon and because there are minimal side effects with its loss. The remainder of the tendon is sutured to the flexor hallucis longus tendon that flexes the big toe so that little function is loss.

Managing Fallen Arches

posted on 03 Apr 2015 12:01 by tanbudget8504
Overview

Flat Feet

Flat feet and fallen arches refer to the same thing. It's a downward sagging of the inside edge of the foot during standing or walking. The front-to-back arches (called the longitudinal arches) are natural curves along the bottoms of both feet that are supported by muscles and ligaments. When these muscles and ligaments give way, the arches sag with each step. When the arches sag, your weight is shifted toward your big toes.




Causes

Fallen arches may be caused by a number of causes, including increased elastin during pregnancy, arthritis, injury, excessive stress on the foot, fused bones in the foot, or an extra bone. They may cause not only foot pain, but also pain in the legs, knees, and back and a loss of mobility. The condition is most often treated with orthotics, structures placed in the shoes to support the feet, but this may not be enough for severe cases. Exercises to strengthen and rebuild the arches can also be helpful. Surgery is sometimes the best method of treatment, as it can completely rebuild the arches and has lasting results, but it is quite expensive and considered a last resort.




Symptoms

Fallen arches may induce pain in the heel, the inside of the arch, the ankle, and may even extend up the body into the leg (shin splints), knee, lower back and hip. You may also experience inflammation (swelling, redness, heat and pain) along the inside of the ankle (along the posterior tibial tendon). Additionally, you may notice some changes in the way your foot looks. Your ankle may begin to turn inward (pronate), causing the bottom of your heel to tilt outward. Other secondary symptoms may also show up as the condition progresses, such as hammertoes or bunions. You may also want to check your footprint after you step out of the shower. (It helps if you pretend you?re in a mystery novel, and you?re leaving wet, footprinty clues that will help crack the case.) Normally, you can see a clear imprint of the front of your foot (the ball and the toes) the heel, and the outside edge of your foot. There should be a gap (i.e. no footprinting) along the inside where your arches are. If your foot is flat, it?ll probably leave an imprint of the full bottom of your foot-no gap to be had. Your shoes may also be affected: because the ankle tilts somewhat with this condition, the heel of your shoes may become more worn on one side than another.




Diagnosis

There are a few simple ways to assess your foot type, and most include making an imprint of your footprint. The classic way is to stand on a hard floor surface with wet feet to make a wet foot print. Look at the narrowest part of your footprint, which should be between your heel and ball of your foot. If the print of your foot in this part is less than 10% of the width of the widest part then you are likely to have high arches. more than 10% but less than 25% then your foot profile is probably normal, more than 25% or even the widest part, then you have flat feet.




Non Surgical Treatment

Treatment of flat feet may be appropriate if there is associated foot or lower leg pain, or if the condition affects the knees or the lower back. Treatment may include using Orthoses such as an arch support, foot gymnastics or other exercises as recommended by a podiatrist/orthotist or physical therapist. In cases of severe flat feet, orthoses should be used through a gradual process to lessen discomfort. Over several weeks, slightly more material is added to the orthosis to raise the arch. These small changes allow the foot structure to adjust gradually, as well as giving the patient time to acclimatise to the sensation of wearing orthoses. Once prescribed, orthoses are generally worn for the rest of the patient's life. In some cases, surgery can provide lasting relief, and even create an arch where none existed before; it should be considered a last resort, as it is usually very time consuming and costly.




Surgical Treatment

Adult Acquired Flat Foot

Surgical correction is dependent on the severity of symptoms and the stage of deformity. The goals of surgery are to create a more functional and stable foot. There are multiple procedures available to the surgeon and it may take several to correct a flatfoot deformity. Stage one deformities usually respond to conservative or non-surgical therapy such as anti-inflammatory medication, casting, functional orthotics or a foot ankle orthosis called a Richie Brace. If these modalities are unsuccessful surgery is warranted. Usually surgical treatment begins with removal of inflammatory tissue and repair of the posterior tibial tendon. A tendon transfer is performed if the posterior tibial muscle is weak or the tendon is badly damaged. The most commonly used tendon is the flexor digitorum longus tendon. This tendon flexes or moves the lesser toes downward. The flexor digitorum longus tendon is utilized due to its close proximity to the posterior tibial tendon and because there are minimal side effects with its loss. The remainder of the tendon is sutured to the flexor hallucis longus tendon that flexes the big toe so that little function is loss. Stage two deformities are less responsive to conservative therapies that can be effective in mild deformities. Bone procedures are necessary at this stage in order to recreate the arch and stabilize the foot. These procedures include isolated fusion procedures, bone grafts, and/or the repositioning of bones through cuts called osteotomies. The realigned bones are generally held in place with screws, pins, plates, or staples while the bone heals. A tendon transfer may or may not be utilized depending on the condition of the posterior tibial tendon. Stage three deformities are better treated with surgical correction, in healthy patients. Patients that are unable to tolerate surgery or the prolonged healing period are better served with either arch supports known as orthotics or bracing such as the Richie Brace. Surgical correction at this stage usually requires fusion procedures such as a triple or double arthrodesis. This involves fusing the two or three major bones in the back of the foot together with screws or pins. The most common joints fused together are the subtalar joint, talonavicular joint, and the calcaneocuboid joint. By fusing the bones together the surgeon is able to correct structural deformity and alleviate arthritic pain. Tendon transfer procedures are usually not beneficial at this stage. Stage four deformities are treated similarly but with the addition of fusing the ankle joint.




After Care

Patients may go home the day of surgery or they may require an overnight hospital stay. The leg will be placed in a splint or cast and should be kept elevated for the first two weeks. At that point, sutures are removed. A new cast or a removable boot is then placed. It is important that patients do not put any weight on the corrected foot for six to eight weeks following the operation. Patients may begin bearing weight at eight weeks and usually progress to full weightbearing by 10 to 12 weeks. For some patients, weightbearing requires additional time. After 12 weeks, patients commonly can transition to wearing a shoe. Inserts and ankle braces are often used. Physical therapy may be recommended. There are complications that relate to surgery in general. These include the risks associated with anesthesia, infection, damage to nerves and blood vessels, and bleeding or blood clots. Complications following flatfoot surgery may include wound breakdown or nonunion (incomplete healing of the bones). These complications often can be prevented with proper wound care and rehabilitation. Occasionally, patients may notice some discomfort due to prominent hardware. Removal of hardware can be done at a later time if this is an issue. The overall complication rates for flatfoot surgery are low.

What Can Cause Bunion Pain?

posted on 29 Mar 2015 07:54 by tanbudget8504
Overview

Bunions Hard Skin

A bunion or hallux abducto valgus occurs when your big toe points toward your second toe. The big toe will touch the second or causes the second toe to overlap the big toe. This causes a boney bump to appear on the outside edge of your big toe. Bunions are more common in women and can sometimes run in families. Hallux abducto valgus can develop as a result of an inherited structural defect or stress on your foot or due to a medical condition such as arthritis. If there is an underlying structural defect in your foot this can lead to compensations causing stresses and pressures to be applied unevenly on the joints and tendons in your feet. This imbalance in pressure and stress makes your big toe joint unstable. Over time this causes the medial side of the 1st metatarsal head to develop excess bone that protrudes out beyond the normal shape of your foot. The size of the bunion can get larger over time which causes further crowding your other toes and causing pain. Pain from a bunion can be severe enough to keep you from walking comfortably in normal shoes. The condition may become painful as the bump gets worse, and extra bone and a fluid-filled sac (bursa) grow at the base of the big toe. By pushing your big toe inward, a bunion can squeeze your other toes into abnormal positions. This crowding can cause the four smaller toes to become bent or a claw-like in shape. These bent toes are known as hammertoes. Smaller bunions called ?bunionettes? can also develop on the joint of your 5th toe.

Causes

The causes of bunions are "multifactorial". In other words generally many things contribute to their occurence. Shoewear per se is a contributory factor but it isn't possible to say that the type of shoewear is necessairily relevant. Often there is a hereditary component with other family members also suffering with the same condition.

Symptoms

In addition to the typical bump, signs of bunions can include red, calloused skin along the foot at the base of the big toe. With bunions, you may also develop calluses on the big toe, sores between the toes, ingrown toenail, and restricted motion of the toe. Some bunions are small and painless and some are large and extremely painful. Pressure from shoes worsens the problem.

Diagnosis

Most patients are diagnosed to have bunions from clinical history and examination. However, in some cases, X-rays will be performed to determine the extent of damage to the joint. Furthermore, it will enable the treating doctor to decide on the best course of management of the patient.

Non Surgical Treatment

Wide shoes with plenty of space for the toes are the first place to start. Along these lines, a shoe can be focally stretched directly over the painful bunion using a device known as a ?ball and ring? shoe stretcher. Additionally, numerous commercial bunion braces and splints are available to help keep the big toe in better alignment.

Bunion Pain

Surgical Treatment

Bunion surgery is both an art and a science, and it should always be performed by a healthcare professional who understands the multifaceted mechanics of your first MTP and its surrounding structures. Bunion surgery involves more than just removing the bump at the base of your big toe, and it is best followed up with supportive therapies to prevent a recurrence of your health problem.

Prevention

Make better shoe choices. If you?re a woman, avoid high-heeled footwear whenever possible (at the very least, choose shoes with heels lower than two inches), and make sure all your footwear has a wide, deep toe box. Whether man or woman, if you?re trying on shoes and your toes feel ?squished? or crowded by a particular shoe, reject that style and try another, or go for a larger size. You don?t need to invite trouble. In general, shoes that come to a point at the toe are bad news, as they tend to push the toes together into an overlapping pattern. Shoes with rocker soles will unload pressure on the bunion area. Examine your feet regularly. Note any redness, swelling or discoloration. Flex your toes and check for any stiffness. If there is any, think back to what you?ve worn or done in the past few days. If the condition persists more than a few days, or worsens, a visit to the podiatric physician is in order.
