Posterior tibial tendon dysfunction is one of the most common problems of the foot and ankle. It occurs when the posterior tibial tendon becomes inflamed or torn. As a result, the tendon may not be able to provide stability and support for the arch of the foot, resulting in flatfoot. The posterior tibial tendon is one of the most important tendons of the leg. A tendon attaches muscles to bones, and the posterior tibial tendon attaches the calf muscle to the bones on the inside of the foot. The main function of the tendon is to hold up the arch and support the foot when walking. The posterior tibial tendon serves as one of the major supporting structures of the foot, helping it to function while walking. Posterior tibial tendon dysfunction (PTTD) is a condition caused by changes in the tendon, impairing its ability to support the arch. This results in flattening of the foot. PTTD is often called "adult acquired flatfoot" because it is the most common type of flatfoot developed during adulthood. Although this condition typically occurs in only one foot, some people may develop it in both feet. PTTD is usually progressive, which means it will keep getting worse, especially if it isn't treated early.
A fallen arch occurs because one of the main structures that support the arch has broken or torn. Usually it occurs without trauma, although a small injury associated with the onset of the pain is often recalled, it is sometimes difficult to determine whether the injury was clearly big enough to permanently injure the leg. I suspect that even before the symptoms that the structure that broke was weakening and the injury was simply the ?needle that broke the camels back?. The structure that is most commonly torn is the posterior tibial tendon. This tendon is attached to a muscle on the inside of the back of the ankle, and runs along the medial malleolus, the bony prominence on the inside of the ankle, to attach to a bone in the arch called the navicular bone. It usually begins to weaken and stretch along the back of the medial malleolus. It often begins as a swelling and the arch flattens over the next several weeks to months. As the arch flattens, other structures that support the arch begin to stretch and tear. The bones along the outside of the ankle begin to crush together, causing pain and swelling in this are, and the toes may tilt to the outside as the arch collapses. It is not known why this process begins. It is often associated with diabetes and rheumatoid arthritis and other inflammatory diseases. It also is more common as a person enters the fifty to seventy year age range. ?Fallen arches? are much more common in people who are already flat footed.
A symptom is something the patient feels and reports, while a sign is something other people, including the doctor may detect. An example of a symptom may be pain in the ankle, while a sign may be a swelling. Symptoms may vary and generally depend on the severity of the condition. Some have an uneven distribution of bodyweight and find that the heel of their shoes wears out more rapidly and more on one side than the other. The most common signs or symptoms of flat feet are pain in the ankle (inner side), there may also be swelling of the foot in general, swelling in the arch of the foot, the calf, knee, the hip, the back, the general lower leg area. People with flat feet may also experience stiffness in one or both feet. One or both feet may be flat on the ground (either no arch, or very slight arch). Shoes may wear unevenly.
Diagnosis of flat feet or fallen arches can be made by your health practitioner and is based on the following. Clinical assessment involving visual gait assessment, as well as biomechanical assessment. A detailed family and medical history. A pain history assessment determining the location of painful symptoms. Physical palpation of the feet and painful areas. Imaging such as MRI or x-ray can be used by your practitioner to assist in the diagnosis.

Non Surgical Treatment
If you have flat feet you may not necessarily need treatment -- sometimes a child or even an adult will have low arches and have no problems. It's normal for a baby's or young child's feet to appear flat until the structure of their feet is more fully developed. If flat feet are contributing to secondary problems, especially leg or foot pain, treatment may be necessary. Flat feet can sometimes cause difficulty walking or running and interfere with athletic activities. A visit to a podiatrist will involve an evaluation of foot structure and function. Besides a foot exam, a visit may include foot X-rays and an analysis of your feet while walking. Your podiatrist may prescribe arch supports or orthotics to control the pronation. While orthotics and arch supports don't permanently correct the shape of the arch, they do help control excess pronation that may be causing wear-and-tear on your muscles and joints. Sneakers with a design called motion control are also helpful for overpronators. This style of sneaker has a design that creates more stability by limiting movement in the heel and arch area of the shoe. Additionally, physical therapy and stretching exercises may be in order, especially if tendonitis (tendon inflammation) is present. Flat feet that are the result of congenital or developmental abnormalities may require further intervention, such as bracing, casting or surgical correction. A brace incorporates an arch support into a device that attaches to the lower leg, giving extra support and flat-foot control. Bracing or foot surgery may also be warranted in cases when flat feet are caused by neurological diseases or are aggravated by posterior tibial tendonitis, which can be a long-term complication of flat feet. Casting is a method used for children whose flat feet are caused by bone positional abnormalities, such as metatarsus adductus. It involves using a series of casts to assist in re-aligning leg and foot bones to their proper anatomical position.
Procedures may include the following. Fusing foot or ankle bones together (arthrodesis). Removing bones or bony growths, also called spurs (excision). Cutting or changing the shape of the bone (osteotomy). Cleaning the tendons' protective coverings (synovectomy). Adding tendon from other parts of your body to tendons in your foot to help balance the "pull" of the tendons and form an arch (tendon transfer). Grafting bone to your foot to make the arch rise more naturally (lateral column lengthening).
Strap the arches into the anatomically correct positions with athletic tape and leave them like this for some time. If the fallen arches are an issue with the muscular structure, this may give the muscles an opportunity to strengthen. This is definitely not a fallen arches cure all the time but it can help prevent it more times than not. Ask a doctor or physical therapists to show you how to do this taping. Find shoes that fit. This may require that you get your foot measured and molded to ensure that the shoe will fit. Shoes that are too big, too tight or too short, may not directly cause the fallen arches, but they can assist with the damage to the area. These shoes should have thick cushioning inside and have plenty of room for your toes. Walk without shoes as much as possible. Shoes directly assist with weakening and distorting the arches of the feet so going without shoes can actually help strengthen your arches and prevent fallen arches. Walking on hard and bumpy surfaces barefooted makes the muscles in your feet strengthen in order to prevent injury. It is a coping mechanism by your body. Insert heel cups or insoles into the shoes that you wear the most. Many people wear uncomfortable shoes to work and these are the same shoes that cause their arches the most problems. Inserting the heel cups and insoles into these shoes can prevent fallen arches from occurring. Many people place these inserts into all their shoes to ensure support. Ask a medical professional, either your doctor or a physical therapist, about daily foot exercises that may keep the arches stronger than normal. Many times, you can find exercises and stretches on the Internet on various websites. Curling your toes tightly and rotating your feet will help strengthen your longitudinal arches. Relax your feet and shake them for a minute or so before you do any arch exercises. This will loosen the muscles in your feet that stay tight due to normal daily activities. Wear rigid soled sandals whenever possible to provide a strong support for your arches. Wooden soled sandals are the best ones if available. Walk or jog on concrete as much as you can. This will create a sturdy support for your arches. Running or walking in sandy areas or even on a treadmill, does not give rigid support. Instead, these surfaces absorb the step, offering no support for arches.
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.
