When sitting, an over-pronating foot appears quite normal, i.e. showing a normal arch with room under the underside of the foot. The moment you get up and put weight on your feet the situation changes: the arches lower and the ankle slightly turns inwards. When you walk or run more weight is placed on the feet compared to standing and over-pronation will become more evident. When walking barefoot on tiles or timber floors over-pronation is more visible, compared to walking on carpet or grass.
Just as there are many different causes of flat feet, there are also many different treatment options. The most important aspect of treatment is determining the exact type or underlying cause of flat feet that you have. Foot and ankle specialists can determine this through thorough clinical examination and special imaging studies (e.g., x-rays, computed tomography, and/or magnetic resonance imaging). Conservative treatment is effective in the vast majority of flat foot cases, and consists of things such as insoles, splints, manipulation, or casting. Surgery is required much less frequently, and is reserved only for some of the severe types of flat foot that do not respond to conservative therapy. You may have noticed that one common element in the conservative treatment of all types of flat feet is orthoses. Many companies now manufacture semi-custom orthotic devices that not only improve comfort, but also seek to control abnormal motion of the foot. These over-the-counter inserts, in the $25 to $50 range, are an economical treatment that may help a majority of people. Unfortunately, these semi-custom devices will not fit everyone perfectly, and those of us who differ too much from the average may respond better to custom orthotic devices. Custom inserts are prescribed by your foot and ankle specialist and are made individually from either a physical or computerized impression of your feet. The only drawback of custom orthoses is their cost, ranging anywhere from $300 to $500. Many physicians recommend trying over-the-counter inserts first (and even keep them in stock) as they may save their patients large sums of money.
Pain and stiffness of the medial arch or anywhere along the mid-portion of the foot. Associated discomfort within and near the ankle joint. The knees, hips, and lower back may be the primary source of discomfort. Feet may often feel tired and achy. Painful shin splints may develop with activity. Gait may be awkward.
Podiatrists are trained in expertly assessing flat feet and identifying different risk factors and the causes for it. Initial assessment will begin with a detailed history attempting to find out if any underlying illness has resulted in this. A detailed clinical examination normally follows. The patient may be asked to perform certain movements such as walking or standing on their toes to assess the function of the foot. Footwear will also be analysed to see if there has been excessive wear or if they are contributing to the pronation of the foot. To assess the structure of the foot further, the podiatrist may perform certain x-rays to get a detailed idea of the way the bones are arranged and how the muscle tissues may be affecting them. It also helps assess any potential birth defects in a bit more detail.
Non Surgical Treatment
What we want to do is support the arch and maintain it in that curved position. So what you want is to bring the foot into a position where you hold and support the arch so you can get that correct heel-midfoot-big toe contact. You would achieve that with a level of arch support. People will take different levels of support, if you?re somebody who has movement in your arch, a strong level of support will hold and maintain you whereas if you?re someone whose arch has collapsed it could need more support and a level of correction built into the support to realign you. If you think of it, when your arch drops, it affects your foot but it also has a biomechanical effect on the rest of the body. But nothing that can?t be solved.
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.
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.
