If you take a close look an adult foot (from the inside) you will notice an inward/upward curve at the center. This curve is known as an arch, and it?s formed by tendons in the foot and lower leg attached at the heel and foot bones. When these tendons pull and attach normally, the foot forms a normal arch. When the tendons don?t pull together properly, they don?t form any arch. This results in flat feet popularly known as fallen arches.
Flat feet are a common condition. In infants and toddlers, the arch is not developed and flat feet are normal. The arch develops in childhood. By adulthood, most people have developed normal arches. When flat feet persist, most are considered variations of normal. Most feet are flexible and an arch appears when the person stands on his or her toes. Stiff, inflexible, or painful flat feet may be associated with other conditions and require attention. Painful flat feet in children may be caused by a condition called tarsal coalition. In tarsal coalition, two or more of the bones in the foot fuse together. This limits motion and often leads to a flat foot. Most flat feet do not cause pain or other problems. Flat feet may be associated with pronation, in which the ankle bones lean inward toward the center line. When the shoes of children who pronate are placed side by side, they will lean toward each other (after they have been worn long enough for the foot position to remodel their sole). Foot pain, ankle pain, or lower leg pain (especially in children) may be a result of flat feet and should be evaluated by a health care provider. Adults can develop a flat foot when they are 60 - 70 years old. This type of flat foot is usually on one side.
Some people have fallen arches, and they aren?t even aware of it, fallen arches are sometimes asymptomatic and do not always cause pain. However, for others, the following symptoms may be present. Foot pain, particularly in the arches or heels, leg or back pain, feet feel tired quickly, swelling in the feet and difficulty moving the feet.
Your doctor examines your feet to determine two things, whether you have flat feet and the cause or causes. An exam may include the following steps, Checking your health history for evidence of illnesses or injuries that could be linked to flat feet or fallen arches, Looking at the soles of your shoes for unusual wear patterns, Observing the feet and legs as you stand and do simple movements, such as raising up on your toes, Testing the strength of muscles and tendons, including other tendons in the feet and legs, such as the Achilles tendon or the posterior tibial tendon, Taking X-rays or an MRI of your feet.
arch support for flat feet
Non Surgical Treatment
Some patients with flat feet may automatically align their limbs in such a way that unpleasant symptoms never develop. In such cases treatment is not usually required. Pain in the foot that is caused by flat feet may be alleviated if the patient wears supportive well-fitted shoes. Some patients say that symptoms improve with extra-wide fitting shoes. Fitted insoles or orthotics (custom-designed arch supports) may relieve pressure from the arch and reduce pain if the patient's feet roll or over-pronate. The benefits of an orthotic only exist while it is being worn. Patients with tendonitis of the posterior tibial tendon may benefit if a wedge is inserted along the inside edge of the orthotic - this takes some of the load off the tendon tissue. Wearing an ankle brace may help patients with posterior tibial tendinitis, until the inflammation comes down. Rest, doctors may advise some patients to rest and avoid activities which may make the foot (feet) feel worse, until the foot (feet) feels better. A combination of an insole and some kind of painkiller may help patients with a ruptured tendon, as well as those with arthritis. Patients with a ruptured tendon or arthritis who find insoles with painkillers ineffective may require surgical intervention. Patients, usually children, whose bones did not or are not developing properly, resulting in flat feet from birth, may require surgical intervention to separate fused bones (rare). Bodyweight management, if the patient is obese the doctor may advise him/her to lose weight. A significant number of obese patients with flat feet who successfully lose weight experience considerable improvement of symptoms.
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.
Going barefoot, particularly over terrain such as a beach where muscles are given a good workout, is good for all but the most extremely flatfooted, or those with certain related conditions such as plantar fasciitis. Ligament laxity is also among the factors known to be associated with flat feet. One medical study in India with a large sample size of children who had grown up wearing shoes and others going barefoot found that the longitudinal arches of the bare footers were generally strongest and highest as a group, and that flat feet were less common in children who had grown up wearing sandals or slippers than among those who had worn closed-toe shoes. Focusing on the influence of footwear on the prevalence of pes planus, the cross-sectional study performed on children noted that wearing shoes throughout early childhood can be detrimental to the development of a normal or a high medial longitudinal arch. The vulnerability for flat foot among shoe-wearing children increases if the child has an associated ligament laxity condition. The results of the study suggest that children be encouraged to play barefooted on various surfaces of terrain and that slippers and sandals are less harmful compared to closed-toe shoes. It appeared that closed-toe shoes greatly inhibited the development of the arch of the foot more so than slippers or sandals. This conclusion may be a result of the notion that intrinsic muscle activity of the arch is required to prevent slippers and sandals from falling off the child?s foot.
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.
