Flatfoot (pes planus) is a condition that occurs when the arch or instep of the foot collapses or touches the standing surface. It is also known as fallen arches or pronation of the feet. The human foot is made up of 26 bones, 33 joints, and over 100 muscles, tendons and ligaments. The arch of the foot is created by tightening of the muscles and various ligaments that support the bones of the arch as well as ligaments that run from the heel to the ball of the foot. The arches distribute weight evenly across the feet and up the legs, and can affect walking. A well-developed arch is balanced between rigidity (for stability) and flexibility (for adapting to surfaces).
Genetic predisposition. Faulty foot mechanics, e.g. excessive pronation. Abnormal bony architecture. Laxity of ligaments. Neuro-muscular disease. Trauma to the leg muscles or major tendons. Inflammatory diseases of the joints e.g. Rheumatoid arthritis. Surgical procedures on the leg and ankle. Limb length inequality. Tight Achilles tendon.
Depending on the cause of the flatfoot, a patient may experience one or more of the different symptoms below. Pain along the course of the posterior tibial tendon which lies on the inside of the foot and ankle. This can be associated with swelling on the inside of the ankle. Pain that is worse with activity. High intensity or impact activities, such as running, can be very difficult. Some patients can have difficulty walking or even standing for long periods of time. When the foot collapses, the heel bone may shift position and put pressure on the outside ankle bone (fibula). This can cause pain on the outside of the ankle. Arthritis in the heel also causes this same type of pain. Patients with an old injury or arthritis in the middle of the foot can have painful, bony bumps on the top and inside of the foot. These make shoewear very difficult. Occasionally, the bony spurs are so large that they pinch the nerves which can result in numbness and tingling on the top of the foot and into the toes. Diabetics may only notice swelling or a large bump on the bottom of the foot. Because their sensation is affected, people with diabetes may not have any pain. The large bump can cause skin problems and an ulcer (a sore that does not heal) may develop if proper diabetic shoewear is not used.
Your doctor will ask about your symptoms and medical history. A physical and foot exam will be done. Flat feet can be diagnosed by appearance. To determine if the foot is rigid, you may be asked to do some simple tasks.
Non Surgical Treatment
Most cases of fallen arches are not painful and need no form of treatment. However, common symptoms of fallen arches can include pain in your feet (particularly in the area of your heel or arch), pain in your feet that persists after long bouts of physical activity or standing up, achy feet, or arch pain when standing on the tips of your toes. Most cases of fallen arches are not preventable. Treatments for fallen arches include, rest, ice, compression, medication to relieve pain, orthotics, or in some cases surgery.
A combination of surgical procedures can be used to reconstruct the flatfoot. Generally, these procedures can be separated into those that correct deformities of the bones and those that repair ligaments and tendons. Your orthopaedic surgeon will choose the proper combination of procedures for your foot. Surgery of the foot can be performed under regional anesthesia, which is numbing the foot and ankle with a nerve or spinal block, or general anesthesia, which may require a breathing tube. A nerve block is often placed behind the knee to reduce pain after surgery.
Flat feet or Fallen Arches cannot be prevented due to congenital of nature or from underlying disease process; however, painful symptoms and future pathology from Flat Feet or Fallen Arches may be prevented by the following. Continue to wear your orthotics for work and exercise to provide stability and maintain function of your feet. Footwear. Continue to wear supportive shoes to maximise the function of your orthotic and prevent excessive movement of the joints in your feet.
