Overview
Fallen arches is one way of describing a flat or pronated foot. This can sometimes be implicated in ongoing problems such as lower back pain, knee pain, ankle pain, shin pain etc. The reason for the pronated foot is often due to the alignment of the bones within the foot, but can be increased by such things as ligament laxity, high body weight and a number of other specific conditions. One of these is posterior tibial dysfunction. This is a progressive disorder which allows the foot to pronate or lower on the inside section and can, if left untreated, result in quite debilitating effects. Causes As children grow, their legs will experience developmental changes that can result in excess flattening of the arches with weight bearing. One example is genu valgum, or knock-knees, a usually normal, temporary condition in children at different stages of growth. A tight calf muscle or Achilles tendon can also contribute to a flat foot. Many children will experience tight calf muscles as they go through growth spurts. Conditions that are present at birth and are often diagnosed early include: metatarsus adductus, calcaneovalgus and congenital vertical talus. Tarsal coalitions are congenitally fused foot bones that cause a rigid flat foot often associated with painful muscle spasms. This type of flat foot is usually diagnosed later in childhood or in adulthood. Any condition that causes loose ligaments can result in a flat foot or lower-than-normal arch. Ligaments are bands of tissue that connect bones to each other and have an important role in giving form to foot arches. An example of a condition that causes loosening of ligaments is pregnancy, where normal hormonal changes relax the ligaments. Diseases that cause loose ligaments include Ehlers-Danlos syndrome, Marfan's syndrome and rheumatoid arthritis. If one leg is longer than the other, one foot may be flat in relation to the other to compensate. Usually the foot on the longer limb will have a flatter arch in an effort to shorten that limb, balancing-out the unevenness. Leg length inequality can be caused by spinal abnormalities such as scoliosis. It can also be due to an actual difference in length of one leg bone compared to the other. Symptoms Having flat feet can be painless and is actually normal in some people. But others with flat feet experience pain in the heel or arch area, difficulty standing on tiptoe, or have swelling along the inside of the ankle. They may also experience pain after standing for long periods of time or playing sports. Some back problems can also be attributed to flat feet. Diagnosis An examination of the foot is enough for the health care provider to diagnose flat foot. However, the cause must be determined. If an arch develops when the patient stands on his or her toes, the flat foot is called flexible and no treatment or further work-up is necessary. If there is pain associated with the foot or if the arch does not develop with toe-standing, x-rays are necessary. If a tarsal coalition is suspected, a CT scan is often ordered. If a posterior tibial tendon injury is suspected, your health care provider may recommend an MRI. What causes pes planus? Non Surgical Treatment Most flexible flat feet are asymptomatic, and do not cause pain. In these cases, there is usually no cause for concern, and the condition may be considered a normal human variant. Flat feet were formerly a physical-health reason for service-rejection in many militaries. However, three military studies on asymptomatic adults (see section below), suggest that persons with asymptomatic flat feet are at least as tolerant of foot stress as the population with various grades of arch. Asymptomatic flat feet are no longer a service disqualification in the U.S. military. Surgical Treatment Surgery for flat feet is separated into three kinds: soft tissue procedures, bone cuts, and bone fusions. Depending on the severity of the flat foot, a person?s age, and whether or not the foot is stiff determines just how the foot can be fixed. In most cases a combination of procedures are performed. With flexible flat feet, surgery is geared at maintaining the motion of the foot and recreating the arch. Commonly this may involve tendon repairs along the inside of the foot to reinforce the main tendon that lifts the arch. When the bone collapse is significant, bone procedures are included to physically rebuild the arch, and realign the heel. The presence of bunions with flat feet is often contributing to the collapse and in most situations requires correction. With rigid flat feet, surgery is focused on restoring the shape of the foot through procedures that eliminate motion. In this case, motion does not exist pre-operatively, so realigning the foot is of utmost importance. The exception, are rigid flat feet due to tarsal coalition (fused segment of bone) in the back of the foot where freeing the blockage can restore function. Overview
Every time you take a step, one of your heels has to support the whole weight of your body. As you move, the load is equal to 20 times your own body weight. The load is softened by a pillow of fat under the heel and a large sinew or ligament (the fibrous tissue that joins muscle and bone together) under the sole of the foot. This sinew is called the plantar fascia and it pulls the heel bone forward (in opposition to the Achilles tendon, which pulls it backwards). If an athlete does not warm up properly or a person with a sedentary job exercises heavily during the weekends, they might overload the muscles of the calf or strain the Achilles tendon, which joins these muscles to the heel bone. When overloaded the tendon becomes tight and painfully inflamed, which places extra strain on the plantar fascia and muscles in the soles of the foot. The strained plantar fascia becomes inflamed and may even develop tiny cracks. This is known as plantar fasciitis. Every time you sit down, sleep or otherwise rest your legs, the muscles of the sole of the foot will contract in an attempt to protect the damaged sinew. The pain in the heel will then no longer be felt. But when you get up again and put weight on the foot, the foot and ankle may feel stiff (because of the inflammation) and the pain will return either at the back of the heel or on the soles of the feet. When you start to move, the plantar fascia may crack even more causing a vicious cycle of damage and pain. Inflammation at the point where the Achilles tendon (at the back of the heel) or the plantar fascia (under the heel) join the heel bone (a bone known as the Calcaneum) stimulates cells that form bone to deposit bone in this area, eventually leading to the build up of a bony prominence on the heel bone called a calcaneal spur. But it's not the spur itself that causes the pain. The spur is a sign of chronic inflammation in the connective tissues, which is the result of a prolonged overload. It should also be pointed out that heel spurs can occur on their own, without plantar fasciitis or pain, or may be linked to some types of arthritis (inflammation of the joints). And plantar fasciitis or Achilles tendonitis don't necessarily lead to spur formation. Causes If it hurts under your heel, you may have one or more conditions that inflame the tissues on the bottom of your foot. When you step on a hard object such as a rock or stone, you can bruise the fat pad on the underside of your heel. It may or may not look discolored. The pain goes away gradually with rest. Doing too much running or jumping can inflame the tissue band (fascia) connecting the heel bone to the base of the toes. The pain is centered under your heel and may be mild at first but flares up when you take your first steps after resting overnight. You may need to do special exercises, take medication to reduce swelling and wear a heel pad in your shoe. When plantar fasciitis continues for a long time, a heel spur (calcium deposit) may form where the fascia tissue band connects to your heel bone. Your doctor may take an X-ray to see the bony protrusion. Treatment is usually the same as for plantar fasciitis: rest until the pain subsides, do special stretching exercises and wear heel pad shoe inserts. Having a heel spur may not cause pain and should not be operated on unless symptoms become chronic. Symptoms Initially, this pain may only be present when first standing up after sleeping or sitting. As you walk around, the muscle and tendon loosen and the pain goes away. As this problem progresses, the pain can be present with all standing and walking. You may notice a knot or bump on the back of the heel. Swelling may develop. In some cases, pressure from the back of the shoe causes pain. Diagnosis A biomechanical exam by your podiatrist will help reveal these abnormalities and in turn resolve the cause of plantar fasciitis. By addressing this cause, the patient can be offered a podiatric long-term solution to his problem. Non Surgical Treatment Home care, in cases that are not severe, home care is probably enough to get rid of heel pain. Rest, avoid running or standing for long periods, or walking on hard surfaces. Avoid activities that may stress the heels. Ice, place an ice-pack on the affected area for about 15 minutes. Do not place bare ice directly onto skin. Footwear. proper-fitting shoes that provide good support are crucial. Athletes should be particularly fussy about the shoes they use when practicing or competing - sports shoes need to be replaced at specific intervals (ask your trainer). Foot supports, wedges and heel cups can help relieve symptoms. Surgical Treatment At most 95% of heel pain can be treated without surgery. A very low percentage of people really need to have surgery on the heel. It is a biomechanical problem and it?s very imperative that you not only get evaluated, but receive care immediately. Having heel pain is like having a problem with your eyes; as you would get glasses to correct your eyes, you should look into orthotics to correct your foot. Orthotics are sort of like glasses for the feet. They correct and realign the foot to put them into neutral or normal position to really prevent heel pain, and many other foot issues. Whether it be bunions, hammertoes, neuromas, or even ankle instability, a custom orthotic is something worth considering. heelsncleavage Prevention You can try to avoid the things that cause heel pain to start avoid becoming overweight, where your job allows, minimise the shock to your feet from constant pounding on hard surfaces, reduce the shocks on your heel by choosing footwear with some padding or shock-absorbing material in the heel, if you have high-arched feet or flat feet a moulded insole in your shoe may reduce the stresses on your feet, if you have an injury to your ankle or foot, make sure you exercise afterwards to get back as much movement as possible to reduce the stresses on your foot and your heel in particular, If you start to get heel pain, doing the above things may enable the natural healing process to get underway and the pain to improve. |
