You arch is the curved, raised area made up of your tarsal and metatarsal bones. It helps distribute some of your body weight off of your heel. It is shaped slightly different for everyone-some have lower or ?flatter? arches than others. This doesn?t always cause pain, but when it does, it can make walking and standing unpleasant and difficult. Generally the muscles and other tissues along the arch and even in the heel ache. The inside of the foot and ankle can also swell uncomfortably. Sometimes arches ?fall? inward from an injury or weakness, flattening out an otherwise normal foot.
At the other end of the spectrum, yet within the same category of congenital flat foot, exist several rare, more severe forms of flat foot. These severe conditions include Vertical Talus, Congenital Calcaneal Valgus, and Tarsal Coalitions - all of which are more rigid (no arch with or without weight on the foot) and definitely symptomatic. Luckily, these are much less common, but can usually be identified by specialists at the time of presentation and treated appropriately. The second category, acquired flat foot, develops over time, rather than at birth. Many different factors can contribute to the development of flat feet. These include the types of shoes a child wears, a child's sitting or sleeping positions, compensation for other abnormalities further up the leg, or more severe factors such as rupture of ligaments or tendons in the foot. Very commonly, the reason for flat feet is that the foot is compensating for a tight Achilles tendon. If the Achilles tendon is tight, then it causes the foot to point down, or to plantarflex (as occurs when stepping on the accelerator of your car). Even minimal amounts of plantarflexion can simulate a longer leg on that particular side, assuming that the other foot is in the normal position. The body therefore tries to compensate by pronating, or flattening out the arch, thereby making up for the perceived extra length on the affected side.
The foot of a newborn with congenital vertical talus typically has a convex rocker-bottom shape. This is sometimes combined with an actual fold in the middle of the foot. The rare person who is diagnosed at an older age often has a "peg-leg" gait, poor balance and heavy calluses on the soles where the arch would normally be. If a child with congenital vertical talus has a genetic disorder, additional symptoms often are seen in other parts of the body.
A professional therapist may use tinels test to diagnose tarsal tunnel syndrome. This involves tapping the nerve just behind the medial malleolus or bony bit of the ankle with a rubber hammer. Pain indicates a positive test. Sometimes it is initially mistaken for plantar fasciitis which also causes pain from the inside heel and throughout the arch of the foot. Neural symptoms (such as tingling or numbness) as well as the location of tenderness when touching the area should help to easily distinguish between the conditions.
Non Surgical Treatment
Cortisone, a type of steroid, is a powerful anti-inflammatory medication. It can be injected into the plantar fascia to reduce inflammation and pain. Your doctor may limit your injections. Multiple steroid injections can cause the plantar fascia to rupture (tear), which can lead to a flat foot and chronic pain. Supportive shoes and orthotics. Shoes with thick soles and extra cushioning can reduce pain with standing and walking. As you step and your heel strikes the ground, a significant amount of tension is placed on the fascia, which causes microtrauma (tiny tears in the tissue). A cushioned shoe or insert reduces this tension and the microtrauma that occurs with every step. Soft silicone heel pads are inexpensive and work by elevating and cushioning your heel. Pre-made or custom orthotics (shoe inserts) are also helpful. Most people sleep with their feet pointed down. This relaxes the plantar fascia and is one of the reasons for morning heel pain. A night splint stretches the plantar fascia while you sleep. Although it can be difficult to sleep with, a night splint is very effective and does not have to be used once the pain is gone. Your doctor may suggest that you work with a physical therapist on an exercise program that focuses on stretching your calf muscles and plantar fascia. In addition to exercises like the ones mentioned above, a physical therapy program may involve specialized ice treatments, massage, and medication to decrease inflammation around the plantar fascia. Extracorporeal shockwave therapy (ESWT). During this procedure, high-energy shockwave impulses stimulate the healing process in damaged plantar fascia tissue. ESWT has not shown consistent results and, therefore, is not commonly performed. ESWT is noninvasive-it does not require a surgical incision. Because of the minimal risk involved, ESWT is sometimes tried before surgery is considered.
As with most surgeries, patients and physicians should consider the surgery only after other, less invasive treatments have proven unproductive. Indications for surgery include Pain. Inability to function. Failure to improve after a six-month course of specific, directed physical therapy. Failure to improve after using arch supports, orthotics, or ankle and foot bracing. Once patients are at that point, the good news is that the procedure has considerably better outcomes than more traditional flat foot surgery. In the past, surgeons would realign and fuse the three hind joints, which would cause patients to lose motion, leaving them with a significantly stiff hind foot, With these newer procedures, if the foot is still flexible, surgeons can realign it and usually restore a close-to-normal or functional range of motion in the joints.
Early in the treatment of arch pain, consideration needs to be given to the cause and strategies put in place to prevent it happening again. Advice should be sought on the adequacy of footwear. Stretching exercises should be continued long after the symptoms are gone. Foot orthoses should be used if structural imbalances are present. Activity levels and types of activities (occupational and sporting) need to be considered and modified accordingly.
