Are Fallen Arches Flat Feet?

Overview



Flat Feet and Fallen Arches are terms used to describe feet that have a low or no arch when weight bearing. There are two types of Flat Feet. Rigid Flat Foot. This type of foot is structurally flat, therefore, it has the same appearance when weight bearing and non weight bearing. Flexible Flat Foot. This is where the arch is present when non-weight bearing; however, when weight bearing it falls or collapses to a flat foot. This foot type is commonly referred to as Fallen Arches. Both of these foot types may be asymptomatic; however, they are characterised by excessive pronation of the joints of the foot (commonly the subtalar joint). The forces associated with this excessive pronation commonly results in pathological conditions, such as plantar fasciitis and tibialis posterior dysfunction which may cause pain in the feet.




Causes

The direct cause of being flat footed is linked to a muscular imbalance in the intrinsic muscles of the foot and ankle. When your main arch-supporting tendon, the posterior tibial tendon, decreases in strength due to muscle decay or injury, the foot begins to flatten and can cause pain during normal activities. Weakness in the tendon can be present at birth due to genetics or can develop from early walking patterns. However, in most people who experience fallen arches, it comes from strain due to aging or placed on the feet from standing or walking in heels for long periods of time. Improper footwear that doesn?t support the arch of the foot, diabetes and obesity can increase your risk of developing fallen arches.




Symptoms

Many people have flat feet and notice no problems and require no treatment. But others may experience the following symptoms, Feet tire easily, painful or achy feet, especially in the areas of the arches and heels, the inside bottom of your feet become swollen, foot movement, such as standing on your toes, is difficult, back and leg pain, If you notice any of these symptoms, it's time for a trip to the doctor.




Diagnosis

Flat feet are easy to identify while standing or walking. When someone with flat feet stands, their inner foot or arch flattens and their foot may roll over to the inner side. This is known as overpronation. To see whether your foot overpronates, stand on tiptoes or push your big toe back as far as possible. If the arch of your foot doesn't appear, your foot is likely to overpronate when you walk or run. It can be difficult to tell whether a child has flat feet because their arches may not fully develop until they're 10 years of age.




Non Surgical Treatment

The simplest form of treatment is the use of custom fitted orthotics. For this, it is best to see a podiatrist, who is a trained medical professional that assesses feet and gives you a prescription for the orthotic. If the orthotics do not work - or if the deformity is very severe - then surgical management may be needed. There is a very wide range of procedures available, with varying downtimes and complexity. The simplest procedure of all is a simple calf release. This can be done at the back of the knee or the calf, and has a very quick recovery. It is a day-surgery procedure, and the patient can walk immediately after the surgery without the need for a cast. Recovery back to jogging can be as early as three weeks. The calf release stops the deforming force but obviously does not correct the arch itself. It is usually done in combination with some of the other procedures mentioned below. Done by itself, the patient will probably still require orthotics but by releasing the calf, it allows the orthotics to be much more effective. The other end of the spectrum is a complete reconstruction of the arch with bone work and screws to fuse joints.




Surgical Treatment



Surgery is typically offered as a last resort in people with significant pain that is resistant to other therapies. The treatment of a rigid flatfoot depends on its cause. Congenital vertical talus. Your doctor may suggest a trial of serial casting. The foot is placed in a cast and the cast is changed frequently to reposition the foot gradually. However, this generally has a low success rate. Most people ultimately need surgery to correct the problem. Tarsal coalition. Treatment depends on your age, extent of bone fusion and severity of symptoms. For milder cases, your doctor may recommend nonsurgical treatment with shoe inserts, wrapping of the foot with supportive straps or temporarily immobilizing the foot in a cast. For more severe cases, surgery is necessary to relieve pain and improve the flexibility of the foot. Lateral subtalar dislocation. The goal is to move the dislocated bone back into place as soon as possible. If there is no open wound, the doctor may push the bone back into proper alignment without making an incision. Anesthesia is usually given before this treatment. Once this is accomplished, a short leg cast must be worn for about four weeks to help stabilize the joint permanently. About 15% to 20% of people with lateral subtalar dislocation must be treated with surgery to reposition the dislocated bone.




After Care

Time off work depends on the type of work as well as the surgical procedures performed. . A patient will be required to be non-weight bearing in a cast or splint and use crutches for four to twelve weeks. Usually a patient can return to work in one to two weeks if they are able to work while seated. If a person's job requires standing and walking, return to work may take several weeks. Complete recovery may take six months to a full year. Complications can occur as with all surgeries, but are minimized by strictly following your surgeon's post-operative instructions. The main complications include infection, bone that is slow to heal or does not heal, progression or reoccurrence of deformity, a stiff foot, and the need for further surgery. Many of the above complications can be avoided by only putting weight on the operative foot when allowed by your surgeon.
