Flat feet- or fallen arches- refers to a condition of the foot in which the arch of the foot collapses while standing (or in some extreme cases, even when no weight is applied to the feet), causing the sole of the foot to become flat.
Most commonly fallen arches in adulthood can arise due to Posterior Tibial Tendon Dysfunction (PTTD). The posterior tibial tendon plays a pivotal role in holding up the arch of the foot, damage to this tendon results in the arch collapsing. Another cause of acquired flat feet in adulthood may be due to Rheumatoid arthritis as this disease attacks the bone, cartilage and ligaments in the foot causing it to change shape and flatten. Injury to the ligament, fracture and/or dislocation of the bones in the mid foot can all lead to a flat foot deformity. Adult acquired flat fleet can also arise in people who have diabetes or a neurological condition which limits normal feeling in the foot, the muscles in feet switch off, the tendons and ligaments weaken, and the arch eventually collapses.
The primary symptom of fallen arches is painful or achy feet in the area in which the foot arches or on the heel. This area may become swollen and painful to stand still on. This causes the patient to improperly balance on their feet which in turn will cause other biomechanical injuries such as back, leg and knee pain.
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.
How do you get an arch in your foot?
Non Surgical Treatment
Treatment for flat feet and fallen arches depends on the severity and cause of the problem. If flat feet cause no pain or other difficulties, then treatment is probably not needed. In other cases, your doctor may suggest one or more of these treatments. Rest and ice to relieve pain and reduce swelling, stretching exercises, pain relief medications, such as nonsteroidal anti-inflammatories, physical therapy, orthotic devices, shoe modifications, braces, or casts, injected medications to reduce inflammation, such as corticosteroids. If pain or foot damage is severe, your doctor may recommend surgery.
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.
