Flexible flatfeet are considered normal in young children because babies are not born with a normal arch. The arch may not form fully until sometime between ages 7 and 10. Even in adulthood, 15% to 25% of people have flexible flatfeet. Most of these people never develop symptoms. In many adults who have had flexible flatfeet since childhood, the missing arch is an inherited condition related to a general looseness of ligaments. These people usually have extremely flexible, very mobile joints throughout the body, not only in the feet. Flatfeet also can develop during adulthood. Causes include joint disease, such as rheumatoid arthritis, and disorders of nerve function (neuropathy). Unlike a flexible flatfoot, a rigid flatfoot is often the result of a significant problem affecting the structure or alignment of the bones that make up the foot's arch. Some common causes of rigid flatfeet include. Congenital vertical talus. In this condition, there is no arch because the foot bones are not aligned properly. In some cases, there is a reverse curve (rocker-bottom foot, in which the shape is like the bottom rails of a rocking chair) in place of the normal arch. Congenital vertical talus is a rare condition present at birth. It often is associated with a genetic disorder, such as Down syndrome, or other congenital disorders. The cause is unknown in up to half of cases. Tarsal coalition (peroneal spastic flatfoot). In this inherited condition, two or more of the foot bones are fused together, interfering with the flexibility of the foot and eliminating the normal arch. A rare condition, it often affects several generations of the same family. Lateral subtalar dislocation. Sometimes called an acquired flatfoot, it occurs in someone who originally had a normal foot arch. In a lateral subtalar dislocation, there is a dislocation of the talus bone, located within the arch of the foot. The dislocated talus bone slips out of place, drops downward and sideways and collapses the arch. It usually occurs suddenly because of a high-impact injury related to a fall from a height, a motor vehicle accident or participation in sports, and it may be associated with fractures or other injuries.
Flat feet are often a congenital problem which has no specific cause. They can however occur after an injury, especially conditions such as Tibialis Posterior Syndrome or more traumatic injuries such as fractures or mid-tarsal joint sprains. The other thing to look out for is Overpronation. Often this is confused with having flat feet (or a fallen arch) although it is not technically the same thing. If an individual does not have flat feet but does overpronate then the arch of their foot appears to be normal when standing. However, when they walk the arch collapses and the foot rolls in excessively. This is more difficult to spot than flat feet. It is estimated that between 60 and 80% of the population overpronate!
Pain along the inside of the foot and ankle, where the tendon lies. This may or may not be associated with swelling in the area. Pain that is worse with activity. High-intensity or high-impact activities, such as running, can be very difficult. Some patients can have trouble walking or standing for a long time. Pain on the outside of the ankle. When the foot collapses, the heel bone may shift to a new position outwards. This can put pressure on the outside ankle bone. The same type of pain is found in arthritis in the back of the foot. The symptoms of PTTD may include pain, swelling, a flattening of the arch, and an inward rolling of the ankle. As the condition progresses, the symptoms will change. For example, when PTTD initially develops, there is pain on the inside of the foot and ankle (along the course of the tendon). In addition, the area may be red, warm, and swollen. Later, as the arch begins to flatten, there may still be pain on the inside of the foot and ankle. But at this point, the foot and toes begin to turn outward and the ankle rolls inward. As PTTD becomes more advanced, the arch flattens even more and the pain often shifts to the outside of the foot, below the ankle. The tendon has deteriorated considerably and arthritis often develops in the foot. In more severe cases, arthritis may also develop in the ankle.
If your child has flatfeet, his or her doctor will ask about any family history of flatfeet or inherited foot problems. In a person of any age, the doctor will ask about occupational and recreational activities, previous foot trauma or foot surgery and the type of shoes worn. The doctor will examine your shoes to check for signs of excessive wear. Worn shoes often provide valuable clues to gait problems and poor bone alignment. The doctor will ask you to walk barefoot to evaluate the arches of the feet, to check for out-toeing and to look for other signs of poor foot mechanics. 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.
What does it mean when you have flat feet?
Non Surgical Treatment
If you have fallen arches, but you are not experiencing any symptoms, then you probably do not need to seek treatment. If you are experiencing discomfort due to fallen arches, there are several treatment options. These treatment options include elevating the feet and applying ice to ease discomfort and reduce swelling, rest, exercises to stretch the feet, physical therapy, medication, such as anti-inflammatories, steroid injections and orthotic devices or customised arch supportsto wear in the shoes. If you have fallen arches and periodically experience pain related to that condition, it is a good idea to get orthotic devicesor custom arch supports, to wear in your shoes. The other treatment options, like medication and ice, will help to ease pain from fallen arches after you have already begun to experience pain. However, orthotic devices or(custom arch supports)can help to prevent pain from occurring at all. This preventative measure helps many people with fallen arches to avoid pain and prevent worsening of their condition. In severe cases of fallen arches, surgery may be required to correct the problem. You can also help to prevent pain and exacerbation of fallen arches by reducing your risk factors. If you are overweight, try to lose weight. Even a small weight loss can reduce the pressure on your feet significantly. If you are diabetic, manage your blood sugar as best as possible. Losing weight often also improves the condition of diabetics. You should also avoid high-impact activities, like running on the road, tennis, and sports that involve jumping. Try a gentler form of exercise, like swimming, instead. If you have fallen arches, orthotic devices or(custom arch supports)are an important component of your treatment and can help to prevent pain.
Rarely does the physician use surgery to correct a foot that is congenitally flat, which typically does not cause pain. If the patient has a fallen arch that is painful, though, the foot and ankle physicians at Midwest Orthopaedics at Rush may perform surgery to reconstruct the tendon and "lift up" the fallen arch. This requires a combination of tendon re-routing procedures, ligament repairs, and bone cutting or fusion procedures.
