Overview
Pes planus is the scientific term that describes low arch or "flat" feet. As podiatric physicians, we are very interested not only in structure but also in function of the feet. While very few people have 20-20 vision, it is also true that very few people have perfect arch structure. High and low arch feet are just the two ends of the spectrum of foot structure. The more deviation from what is considered perfect, the worse the function becomes. We describe deviation from "the ideal" as imbalance in structure. It is the imbalance in structure that leads to abnormal function. Abnormal function causes pain and/or deformity. Deformity can manifest itself in a variety of foot problems such as bunions or hammertoes. Likewise, pain can manifest itself in a variety of ways such as heel pain ( plantar fasciitis or heel spur), corns or calluses, metatarsalgia or pain in the ball of the foot ( neuromas, stress fractures, or tendonitis), or even in pediatric problems. Invariably, we can treat most foot imbalance or biomechanical insufficiencies with orthotic therapy.
Causes
There are a variety of causes of flat feet. Flat feet can be genetic, acquired and develop over time. Young children and teens can have no arches. Injury can lead to flat feet. Tendon problems, and arthritis can lead to flat feet. Rigid flat feet may occur from a condition called tarsal coalition, where the bones in the back of the foot are genetically fused or locked together.
Symptoms
Bones and ligaments work together to form joints, and bones are joined together by ligaments. Strains occur in ligaments. In the arch, there are ligaments that are located at the ends of each bone. These ligaments connect the bones to other bones on both ends and on the sides. Point tenderness and looseness of a joint are indicators of a sprain. Fractures are indicated by point tenderness that may be severe over the area of bone that is affected. There may be a distinguishable lump or gap at the site of the fracture. A rotated toe or forefoot may also be a sign of a fracture.
Diagnosis
Magnetic Resonance Imaging (MRI) can show tendon injury and inflammation but cannot be relied on with 100% accuracy and confidence. The technique and skill of the radiologist in properly positioning the foot with the MRI beam are critical in demonstrating the sometimes obscure findings of tendon injury around the ankle. Magnetic Resonance Imaging (MRI) is expensive and is not necessary in most cases to diagnose posterior tibial tendon injury. Ultrasound has also been used in some cases to diagnose tendon injury, but this test again is usually not required to make the initial diagnosis.
Non Surgical Treatment
The treatment is to put an arch support under the foot immediately to prevent the arch from collapsing and the plantar fascia from stretching. Also, put an arch support in your slippers and wear them as soon as you rise. Even a few steps barefoot without support can stretch the plantar fascia. Arch supports usually relieve pain within a few days. To head off arch pain, begin an exercise routine slowly, take off any excess weight and wear arch supports in your athletic shoes. Arch pain commonly smolders for months because people do not take the proper precautions. Continuing to do weight-bearing exercises will perpetuate the pain. While the foot is recovering, swim or do water workouts. Or work the upper body only. Some people are able to use a stationary bicycle by placing only the front part of the foot on the pedals.
Surgical Treatment
Foot surgery is difficult, especially when large amounts of deformity correction are needed. The ability to bring the foot into a new position may not be lasting, even if everything looks perfect in the operating room. The goal is to provide improved position and function of the foot and ankle. In some patients with very severe deformity, the goal is a foot that functions well in a brace. There are complications that relate to surgery in general. These include the risks associated with anesthesia, infection, damage to nerves and blood vessels, and bleeding or blood clots. Particular complications associated with cavus foot surgery include incomplete correction of deformity, return of deformity and incomplete fusion.
Stretching Exercises
Try these simple stretches to assist with relieving pain in your arches. (Note: Stretch slowly and gently. You should feel a moderate pull on the muscle and tendon but no pain. If these stretches are painful, stop and seek further advice from a health professional). STRETCH ONE. Stand at arm?s length from a wall with one foot in front of the other, forward knee bent. Keeping your back leg straight and back heel on the floor, lean into the wall until you feel a stretch in your calf. STRETCH TWO. This time, bend your back leg slightly, and lean into the wall. You should feel a stretch in the lower part of your calf. Hold each stretch for 20 seconds and repeat on each leg, a few times daily.
