Over-pronation, or flat feet, is a common biomechanical problem that occurs in the walking process when a person?s arch collapses upon weight bearing. This motion can cause extreme stress or inflammation on the plantar fascia, possibly causing severe discomfort and leading to other foot problems.
Flat feet don't automatically mean you have a problem. The problem can be divided into a flexible flat foot or rigid flat foot. The rigid flat foot is one that does not change shape when the foot becomes weight bearing. i.e. it does not go through the excessive motion of pronation. Generally speaking this foot does not provide too many problems. The flexible flat foot is the type that when it becomes weight bearing the foot and ankle tends to roll in (pronates) too far. This type of person will often say I have great arches but when I stand up much of this arch disappears as the foot excessively pronates When the foot is excessively pronating and causing problems like sore ankles, feet or knees when standing or exercising then arch support is extremely important to restore the foot structure.
Overpronation can lead to injuries and pain in the foot, ankle, knee, or hip. Overpronation puts extra stress on all the bones in the feet. The repeated stress on the knees, shins, thighs, and pelvis puts additional stress on the muscles, tendons, and ligaments of the lower leg. This can put the knee, hip, and back out of alignment, and it can become very painful.
You can test for pronation by looking at the leg and foot from the back. Normally you can see the Achilles Tendon run straight down the leg into the heel. If the foot is pronated, the tendon will run straight down the leg, but when it lies on the heel it will twist outward. This makes the inner ankle bone much more prominent than the outer ankle bone.
Non Surgical Treatment
Adequate footwear can often help with conditions related to flat feet and high arches. Certified Pedorthists recommend selecting shoes featuring heel counters that make the heel of the shoe stronger to help resist or reduce excessive rearfoot motions. The heel counter is the hard piece in the back of the shoe that controls the foot?s motion from side-to-side. You can quickly test the effectiveness of a shoe?s heel counter by placing the shoe in the palm of your hand and putting your thumb in the mid-portion of the heel, trying to bend the back of the shoe. A heel counter that does not bend very much will provide superior motion control. Appropriate midsole density, the firmer the density, the more it will resist motion (important for a foot that overpronates or is pes planus), and the softer the density, the more it will shock absorb (important for a cavus foot with poor shock absorption) Wide base of support through the midfoot, to provide more support under a foot that is overpronated or the middle of the foot is collapsed inward.
Depending on the severity of your condition, your surgeon may recommend one or more treatment options. Ultimately, however, it's YOUR decision as to which makes the most sense to you. There are many resources available online and elsewhere for you to research the various options and make an informed decision.
It is important to know that foot pain is not only limited to grown-ups. Often active, healthy children will complain of pain in one or both heels shortly after walking, running, engaging or playing sports. The pain is usually felt at the back of, or under the heel. The cause of heel pain in children is usually a condition called calcaneal apophysitis or Sever's Disease, normally reported by 8 to 14 year olds.
During the growth spurt of early puberty, the heel bone (also called the calcaneus) sometimes grows faster than the leg muscles and tendons. This can cause the muscles and tendons to become very tight and overstretched, making the heel less flexible and putting pressure on the growth plate. The Achilles tendon (also called the heel cord) is the strongest tendon that attaches to the growth plate in the heel. Over time, repeated stress (force or pressure) on the already tight Achilles tendon damages the growth plate, causing the swelling, tenderness, and pain of Sever's disease. Such stress commonly results from physical activities and sports that involve running and jumping, especially those that take place on hard surfaces, such as track, basketball, soccer, and gymnastics.
Pain is usually related to activity levels. In most cases the posterior aspect of the calcaneus will be tender. Checking both the medial and lateral aspects of the posterior portion of the growth plate will often show tenderness. Occasionally, the plantar aspect may be tender or both of these locations may be found to be tender. Frequently the Achilles tendon is tight and there may have been a recent increase in activity. The factors contributing to this disorder are similar to those causing plantar fasciitis, but a tight Achilles tendon appears to be a greater contributor than pronation.
Sever?s disease can be diagnosed based on your history and symptoms. Clinically, your physiotherapist will perform a "squeeze test" and some other tests to confirm the diagnosis. Some children suffer Sever?s disease even though they do less exercise than other. This indicates that it is not just training volume that is at play. Foot and leg biomechanics are a predisposing factor. The main factors thought to predispose a child to Sever?s disease include a decrease in ankle dorsiflexion, abnormal hind foot motion eg overpronation or supination, tight calf muscles, excessive weight-bearing activities eg running.
Non Surgical Treatment
Treatment depends on the severity of the condition, but may include relative rest and modified activity, a physiotherapist can help work out what, and how much, activity to undertake. Cold packs, apply ice or cold packs to the back of the heels for around 15 minutes after any physical activity, including walking. Shoe inserts, small heel inserts worn inside the shoes can take some of the traction pressure off the Achilles tendons. This will only be required in the short term. Medication, pain-relieving medication may help in extreme cases, but should always be combined with other treatment and following consultation with your doctor). Anti-inflammatory creams are also an effective management tool. Splinting or casting, in severe cases, it may be necessary to immobilise the lower leg using a splint or cast, but this is rare. Time, generally the pain will ease in one to two weeks, although there may be flare-ups from time to time. Correction of any biomechanical issues, a physiotherapist can identify and discuss any biomechanical issues that may cause or worsen the condition. Education on how to self-manage the symptoms and flare-ups of Sever?s disease is an essential part of the treatment.
Pain or strain in your foot arches is a common sports injury and often linked to inflammation of the plantar fascia, the shock absorption ligament along the bottom of each foot. The pain can also highlight underlying issues to do with the structure of your arches. Arch pain or arch strain, refers to an inflammation and/or burning sensation at the arch of the foot. It is caused by an inflammation which can be brought about by excessive stretching of the plantar fascia, usually due to over-pronation. Left untreated, strain on the longitudinal arch continues and spurs may develop.
Spending a lot of time on your feet. Especially when you are not used to doing so. For example you may have started a new job such as waiting tables where you are on your feet all day and wake up the next day with sore feet. This is a sign of damage and over time could lead to plantar fasciitis. Being Over-Weight. Never an easy topic to discuss but in simple terms, the heavier you are, the greater the burden on your feet. There are times when you're walking when your entire body weight is borne on one leg and therefore one foot, placing great strain on the plantar fascia. Wearing shoes with poor arch support or cushioning. A tight Achilles tendon. This is the big tendon at the bottom of your calf muscles above your heel. If this is excessively tight this can affect your ability to flex your ankle and make you more likely to damage your plantar fascia. Suddenly changing your exercise routine. Using running as an example if you suddenly run many more miles than your are used to or change to a new running surface e.g. grass to tarmac - these factors can put excessive strain on the plantar fascia and lead to plantar fasciitis. All of these risk factors ultimately lead to a specific change in foot structure. The term given is over-pronation and this basically describes rolling in of the foot and lowering of the arches. It is this change that excessively elongates the plantar fascia which can lead to plantar fasciitis.
The primary symptom is pain or aching in the arch area. This can be accompanied by inflammation and tenderness. If the pain is caused by the plantar fascia, it is likely to be considerably more severe in the mornings due to the muscles being unused.
The doctor will examine your feet for foot flexibility and range of motion and feel for any tenderness or bony abnormalities. Depending on the results of this physical examination, foot X-rays may be recommended. X-rays are always performed in a young child with rigid flatfeet and in an adult with acquired flatfeet due to trauma.
Non Surgical Treatment
There is considerable debate about the best treatment option for plantar fasciitis. Some authors suggest all of the 'mainstream' methods of treatment don't actually help at all and can actually make the symptoms worse. However, on the whole, there are several of the most commonly cited treatment options for plantar fasciitis and these are generally accepted throughout the medical community. I would recommend giving these options a try if you haven't already. Rest. This is mainly applicable to the sports people as rest is possible treatment. (For those who cannot rest e.g. people who work on their feet - skip to the other treatment options below). Rest until it is not painful. This is made more difficult as people need to use their feet to perform daily activities but certainly stop sporting activities that are likely to be putting the fascia under excessive stress. Perform Self Micro-Massage (you can watch this video by clicking the link or scrolling further down the page as it's embedded on this lens!) This massage technique is used to break down fibrous tissue and also to stimulate blood flow to the area, both of which encourage healing and reduce pain. There is also a potentially soothing effect on nerve endings which will contribute to pain relief. Ice/Cold Therapy. Particularly useful after spending periods on your feet to reduce the inflammation. Wrap some ice or a bag of frozen peas in a towel and hold against the foot for up to 10 minutes. Repeat until symptoms have resolved. Heat Therapy. Heat therapy can be used (not after activity) to improve blood flow to the area to encourage healing. A heat pack of hot water bottle can be used. 10 minutes is ideal. Careful not to burn yourself. A good taping technique. By taping the foot in a certain way you can limit the movement in the foot and prevent the fascia from over-stretching and gives it a chance to rest and heal. Click on the link for more information on taping techniques. Weight Management. If you are over-weight, any weight you can loose will help to ease the burden on your sore feet and plantar fascia. Orthotic devices (often mis-spelled orthodic) are special insoles that can be used to limit over-pronation (discussed earlier) and control foot function. By preventing the arches flattening excessively, the plantar fascia is not over-stretched to the same extent and this should help with the symptoms and encourage healing. Stretching the calf muscles (again, click this link or scroll to the bottom of the page to watch the embedded video) can help to lengthen these muscles and the Achilles tendon - a risk factor for plantar fasciitis. Stretching of the plantar fascia itself is also encouraged, particularly before getting up the morning (night splints can be used for this effect) and after periods of rest. This can be achieved by placing a towel or band under the ball of the foot and gently pulling upwards until a stretch is felt. Hold for about 15-20 seconds then rest briefly. Repeat 2-3 times. As you can see there are many different treatment options available. Try incorporating some of these in to your daily routine and see what works for you. Regardless of the method the main aim is to prevent the fascia from over-stretching. Medical professionals such as a Podiatrist may decide to make custom orthotics or try ultra-sound therapy. It is likely that anti-inflammatory medications will also be recommended. If you have tried the treatment options and your symptoms persist I'd recommend going to see a medical professional for further advice.
Tendon transfers: Too much pull of certain muscles and tendons is often the cause of the deformity related with a cavus foot. Moving one of these muscles or tendons may help the foot work better. In addition, patients with a cavus foot may have weakness in moving the foot up, which is sometimes called a foot drop. In these cases, a tendon from the back of the ankle may be moved to the top of the foot to help improve strength. Correcting the deformity of the foot may not be possible with soft tissue procedures alone. In these instances, one or more bone cuts (osteotomies) may be needed. Instead of a bone cut, a fusion (arthrodesis) procedure may be used. A fusion removes the joint between two bones so they grow together over time. During a fusion the bones may be held in place with plates or screws. Calcaneal osteotomy: This procedure is performed to bring the heel bone back under the leg. This is needed if correction of the deformity in the front of the foot does not also correct the back of the foot or ankle. A calcaneal osteotomy can be performed several ways and is often held in place with one or more screws. Sometimes patients have a deformity that has caused damage to the joints. In these cases, soft tissue procedures or bone cuts may not be enough, and it may be necessary to eliminate the joint. Clawed toes are a common problem with cavus foot deformity. This can be treated with tendon surgery, fusion or removal of part of the toe bones. Following surgery the toes are often temporarily held in place with pins.
Stretch and strengthen important muscles in your feet, ankles and legs in order to guard against future strain. Make sure to acquire suitable arch supports and inserts if necessary, and that your shoes are shock absorbent and in good condition. Wearing tattered shoes provides no protection, and runners should replace their footwear before exceeding 500 miles of usage. Athletes new to arch supports should gradually build their training routine, allowing their feet to become accustomed to a new stance.
You may start exercising the muscles of your foot right away by gently stretching and strengthening them. Frozen can roll. Roll your bare injured foot back and forth from your heel to your mid-arch over a frozen juice can. Repeat for 3 to 5 minutes. This exercise is particularly helpful if it is done first thing in the morning. Towel stretch. Sit on a hard surface with your injured leg stretched out in front of you. Loop a towel around your toes and the ball of your foot and pull the towel toward your body keeping your leg straight. Hold this position for 15 to 30 seconds and then relax. Repeat 3 times. Standing calf stretch. Stand facing a wall with your hands on the wall at about eye level. Keep your injured leg back with your heel on the floor. Keep the other leg forward with the knee bent. Turn your back foot slightly inward (as if you were pigeon-toed). Slowly lean into the wall until you feel a stretch in the back of your calf. Hold the stretch for 15 to 30 seconds. Return to the starting position. Repeat 3 times. Do this exercise several times each day. Seated plantar fascia stretch. Sit in a chair and cross the injured foot over the knee of your other leg. Place your fingers over the base of your toes and pull them back toward your shin until you feel a comfortable stretch in the arch of your foot. Hold 15 seconds and repeat 3 times. Plantar fascia massage. Sit in a chair and cross the injured foot over the knee of your other leg. Place your fingers over the base of the toes of your injured foot and pull your toes toward your shin until you feel a stretch in the arch of your foot. With your other hand, massage the bottom of your foot, moving from the heel toward your toes. Do this for 3 to 5 minutes. Start gently. Press harder on the bottom of your foot as you become able to tolerate more pressure.
Overview The Achilles tendon is a conjoined tendon composed of the gastrocnemius and soleus muscles with occasional contribution from the plantaris muscle, and it inserts on the calcaneal tuberosity. The plantaris muscle is absent in 6% to 8% of individuals. The Achilles tendon is approximately 15-cm long and is the largest and strongest tendon in the human body. The tendon spirals approximately 90 from its origin to its insertion and this twisting produces an area of stress approximately 2- to 5-cm proximal to its insertion. The tendon has no true synovial sheath; instead it is wrapped in a paratenon. The Achilles tendon experiences the highest loads of any tendon in the body, and bears tensile loads up to 10 times body weight during athletic activities. The tendon most commonly ruptures in a region 2- to 6-cm proximal to its insertion. Causes Factors that may increase your risk of Achilles tendon rupture include Age. The peak age for Achilles tendon rupture is 30 to 40. Your sex. Achilles tendon rupture is up to five times more likely to occur in men than in women. Playing recreational sports. Achilles tendon injuries occur more often in sports that involve running, jumping and sudden starts and stops - such as soccer, basketball and tennis. Steroid injections. Doctors sometimes inject steroids into an ankle joint to reduce pain and inflammation. However, this medication can weaken nearby tendons and has been associated with Achilles tendon ruptures. Certain antibiotics. Fluoroquinolone antibiotics, such as ciprofloxacin (Cipro) or levofloxacin (Levaquin), increase the risk of Achilles tendon rupture. Symptoms Whereas calf strains and tendonitis may cause tightness or pain in the leg, Achilles tendon ruptures are typically accompanied by a popping sensation and noise at the time of the injury. In fact, some patients joke that the popping sound was loud enough to make them think theyd been shot. Seeing a board-certified orthopedic surgeon is the best way to determine whether you have suffered an Achilles tendon tear. Diagnosis If an Achilles tendon rupture is suspected, it is important to consult a doctor straight away so that an accurate diagnosis can be made and appropriate treatment recommended. Until a doctor can be consulted it is important to let the foot hang down with the toes pointed to the ground. This prevents the ends of the ruptured tendon pulling any farther apart. The doctor will take a full medical history, including any previous Achilles tendon injuries and what activity was being undertaken at the time the present injury occurred. The doctor will also conduct a physical examination and will check for swelling, tenderness and range of movement in the lower leg and foot. A noticeable gap may be able to be felt in the tendon at the site of the rupture. This is most obvious just after the rupture has occurred and swelling will eventually make this gap difficult to feel. One test commonly used to confirm an Achilles tendon rupture is the Thomson test. For this test the patient lies face down on an examination table. The doctor then squeezes the calf muscles; an action that would normally cause the foot to point like a ballerina (plantar flexion). When a partial rupture has occurred the foot's ability to point may be decreased. When a complete rupture has occurred, the foot may not point at all. Ultrasound scanning of the Achilles tendon may also be recommended in order to assist with the diagnosis. Non Surgical Treatment Treatment for a ruptured Achilles tendon often depends on your age, activity level and the severity of your injury. In general, younger and more active people often choose surgery to repair a completely ruptured Achilles tendon, while older people are more likely to opt for nonsurgical treatment. Recent studies, however, have shown fairly equal effectiveness of both operative and nonoperative management. Nonsurgical treatment. This approach typically involves wearing a cast or walking boot with wedges to elevate your heel, which allows your torn tendon to heal. This method avoids the risks associated with surgery, such as infection. However, the likelihood of re-rupture may be higher with a nonsurgical approach, and recovery can take longer. If re-rupture occurs, surgical repair may be more difficult. Surgical Treatment The surgical repair of an acute or chronic rupture of the Achilles tendon typically occurs in an outpatient setting. This means the patient has surgery and goes home the same day. Numbing medicine is often placed into the leg around the nerves to help decrease pain after surgery. This is called a nerve block. Patients are then put to sleep and placed in a position that allows the surgeon access to the ruptured tendon. Repair of an acute rupture often takes somewhere between 30 minutes and one hour. Repair of a chronic rupture can take longer depending on the steps needed to fix the tendon. Prevention Here are some suggestions to help to prevent this injury. Corticosteroid medication such as prednisolone, should be used carefully and the dose should be reduced if possible. But note that there are many conditions where corticosteroid medication is important or lifesaving. Quinolone antibiotics should be used carefully in people aged over 60 or who are taking steroids.
