![]() ![]() The patients concerned often have trouble finding appropriate shoes that offer enough space for their deformed feet. Consequently, the second and the third metatarso-phalangeal bone have to carry a bigger load, and painful calluses occur on the sole of the foot. This results in a malposition of the metatarso-phalangeal joints (claw foot, hammer toe,) and corns may form. The flattening of the forefoot and the foot's falling arch often leads to bunions (hallux valgus), and at the same time the little toe starts to point inwards. Most commonly, pain in splay feet occurs when they are overstrained, in particular whilst walking or standing, and disappears when in a resting position. Although mostly caused by a congenital malposition, injuries, paralysis, weak ligaments and bone diseases may also be a cause. As such, the disease often occurs in the second half of life, though even children can be affected. In the case of extra weight, feet have to carry a load that is beyond their capacities, which may result in the condition of splay feet. Two of the main causes of splay feet are being overweight or wearing unsuitable footwear. Women are more commonly affected by splay feet than men. As a result, certain parts of the foot do not carry weight anymore, which cause very painful and highly unsightly calluses and pressure sores to appear. The transverse bulge of the foot disappears and the forefoot is broadened. Splay feet are the most common foot deformity. Because of the pain, the normal rolling mechanism of the foot is disturbed and the patients instinctively malposition their foot causing the shoe to become crooked and bend outwardly. Often this is accompanied by a painful callused protrusion that is tender under pressure. The forefoot is broadened and the metatarsal bones splay fan-shaped. With a splay foot, the transverse bulge of the forefoot disappears, causing, according to the degree of severity, the foot to be strained in places not used to pressure. The footprint widens and the load on the forefoot changes. Thomas Schneider The metatarsals are fanned out in splayfoot instead of pointing straight ahead. ![]()
