What'S Adult Aquired FlatFoot ?

Overview
Noticed that your foot is getting flatter and more painful? Do you have difficulty walking or performing exercise activity without leg and arch pain? Have you heard the term "fallen arches"? All of these things refer to a condition known as posterior tibial tendon dysfunction. This is an inflammation and overuse syndrome of one of the long tendons that pass from the leg around the inside of the ankle and attaches to the inside arch of the foot. The posterior tibial tendon?s job is to help support the arch and allow for more efficient gait. Adult Acquired Flat Feet

Causes
The posterior tibial tendon, which connects the bones inside the foot to the calf, is responsible for supporting the foot during movement and holding up the arch. Gradual stretching and tearing of the posterior tibial tendon can cause failure of the ligaments in the arch. Without support, the bones in the feet fall out of normal position, rolling the foot inward. The foot's arch will collapse completely over time, resulting in adult acquired flatfoot. The ligaments and tendons holding up the arch can lose elasticity and strength as a result of aging. Obesity, diabetes, and hypertension can increase the risk of developing this condition. Adult acquired flatfoot is seen more often in women than in men and in those 40 or older.

Symptoms
Pain along the inside of the foot and ankle, where the tendon lies. This may or may not be associated with swelling in the area. Pain that is worse with activity. High-intensity or high-impact activities, such as running, can be very difficult. Some patients can have trouble walking or standing for a long time. Pain on the outside of the ankle. When the foot collapses, the heel bone may shift to a new position outwards. This can put pressure on the outside ankle bone. The same type of pain is found in arthritis in the back of the foot. Asymmetrical collapsing of the medial arch on the affected side.

Diagnosis
Diagnostic testing is often used to diagnose the condition and help determine the stage of the disease. The most common test done in the office setting are weightbearing X-rays of the foot and ankle. These assess joint alignment and osteoarthritis. If tendon tearing or rupture is suspected, the gold standard test would be MRI. The MRI is used to check the tendon, surrounding ligament structures and the midfoot and hindfoot joints. An MRI is essential if surgery is being considered.

Non surgical Treatment
The adult acquired flatfoot is best treated early. Accurate assessment by your doctor will determine which treatment is suitable for you. Reduce your level of activity and follow the RICE regime. R - rest as often as you are able. Refrain from activity that will worsen your condition, such as sports and walking. I - ice, apply to the affected area, ensure you protect the area from frostbite by applying a towel over the foot before using the ice pack. C - compression, a Tubigrip or elasticated support bandage may be applied to relieve symptoms and ease pain and discomfort. E - elevate the affected foot to reduce painful swelling. You will be prescribed pain relief in the form of non-steroidal antiinflammatory medications (if you do not suffer with allergies or are asthmatic). Immobilisation of your affected foot - this will involve you having a below the knee cast for four to eight weeks. In certain circumstances it is possible for you to have a removable boot instead of a cast. A member of the foot and ankle team will advise as to whether this option is suitable for you. Footwear is important - it is advisable to wear flat sturdy lace-up shoes, for example, trainers or boots. This will not only support your foot, but will also accommodate orthoses (shoe inserts).

Surgical Treatment
Surgery is usually performed when non-surgical measures have failed. The goal of surgery is to eliminate pain, stop progression of the deformity and improve a patient?s mobility. More than one technique may be used, and surgery tends to include one or more of the following. The tendon is reconstructed or replaced using another tendon in the foot or ankle The name of the technique depends on the tendon used. Flexor digitorum longus (FDL) transfer. Flexor hallucis longus (FHL) transfer. Tibialis anterior transfer (Cobb procedure). Calcaneal osteotomy - the heel bone may be shifted to bring your heel back under your leg and the position fixed with a screw. Lengthening of the Achilles tendon if it is particularly tight. Repair one of the ligaments under your foot. If you smoke, your surgeon may refuse to operate unless you can refrain from smoking before and during the healing phase of your procedure. Research has proven that smoking delays bone healing significantly.
