The collapse of the arch, which many refer to as “flat feet”, is a common condition seen in patients of all ages. Flat feet are easily noticed by yourself or a family member – who is possibly also affected, as the condition is hereditary in nature. There are also numerous other causes. Consequences of flat feet include pain in the feet, ankles, legs, knees, hips and lower back in particular. The development of bunions can also be an indication of hyperpronation (excessive inward motion of the feet) of the feet. During loading (standing) and walking, the collapsed arch increases the stress and inflammation of various musculoskeletal structures of the lower limbs. Ligamentous hyperlaxity, pregnancy, obesity, heredity, unequal leg length and other causes can lead to the appearance of flat feet. This type of foot condition does not necessarily present any symptoms, but it’s not uncommon to see several pathologies develop, such as: plantar fasciitis, Lenoir’s heel spur syndrome, Achilles tendonitis (inflammation of the Achilles tendon), posterior tibial tendon dysfunction (a muscle in the leg extending to the foot), metatarsalgia, sesamoiditis, knee pain and back pain.
