Overview
Adult acquired flat foot was first described in the late 1960s as something that occurred after trauma, as a result of a tear to the tibial posterior tendon. However, by 1969 two doctors called Kettlekamp and Alexander described cases in which no trauma had taken place. They referred to the condition as "tibial posterior tendon dysfunction" and this became known as the most common type of adult acquired flat foot.
Causes
There are numerous causes of acquired Adult Flatfoot, including, trauma, fracture, dislocation, tendon rupture/partial rupture or inflammation of the tendons, tarsal coalition, arthritis, neuroarthropathy and neurologic weakness. The most common cause of acquired Adult Flatfoot is due to overuse of a tendon on the inside of the ankle called the posterior tibial tendon. This is classed as - posterior tibial tendon dysfunction. What are the causes of Adult Acquired flat foot? Trauma, Fracture or dislocation. Tendon rupture, partial tear or inflammation. Tarsal Coalition. Arthritis. Neuroarthropathy. Neurological weakness.
Symptoms
The first stage represents inflammation and symptoms originating from an irritated posterior tibial tendon, which is still functional. Stage two is characterized by a change in the alignment of the foot noted on observation while standing (see above photos). The deformity is supple meaning the foot is freely movable and a ?normal? position can be restored by the examiner. Stage two is also associated with the inability to perform a single-leg heel rise. The third stage is dysfunction of the posterior tibial tendon is a flatfoot deformity that becomes stiff because of arthritis. Prolonged deformity causes irritation to the involved joints resulting in arthritis. The fourth phase is a flatfoot deformity either supple (stage two) or stiff (stage 3) with involvement of the ankle joint. This occurs when the deltoid ligament, the major supporting structure on the inside of the ankle, fails to provide support. The ankle becomes unstable and will demonstrate a tilted appearance on X-ray. Failure of the deltoid ligament results from an inward displacement of the weight bearing forces. When prolonged, this change can lead to ankle arthritis. The vast majority of patients with acquired adult flatfoot deformity are stage 2 by the time they seek treatment from a physician.
Diagnosis
Although you can do the "wet test" at home, a thorough examination by a doctor will be needed to identify why the flatfoot developed. Possible causes include a congenital abnormality, a bone fracture or dislocation, a torn or stretched tendon, arthritis or neurologic weakness. For example, an inability to rise up on your toes while standing on the affected foot may indicate damage to the posterior tibial tendon (PTT), which supports the heel and forms the arch. If "too many toes" show on the outside of your foot when the doctor views you from the rear, your shinbone (tibia) may be sliding off the anklebone (talus), another indicator of damage to the PTT. Be sure to wear your regular shoes to the examination. An irregular wear pattern on the bottom of the shoe is another indicator of acquired adult flatfoot. Your physician may request X-rays to see how the bones of your feet are aligned. Muscle and tendon strength are tested by asking you to move the foot while the doctor holds it.
Non surgical Treatment
Treating PTTD is almost always easier the earlier you catch it. So, the first step in treatment is to see your doctor as soon as you begin experiencing painful symptoms. However, once your condition has been diagnosed, your podiatrist will likely try to give the upset tendon a bit of a break so it?ll calm down and stop being so painful. This can often be accomplished by immobilizing the foot using tape and padding, braces, or casts, depending on what your podiatrist believes will work best for you, and depending on the severity of your condition. You may also be instructed to reduce inflammation by applying ice to the area (usually 40 minutes on and 20 minutes off, with a thin towel between you and the ice). Or, you might take anti-inflammatory medications like ibuprofen (steroidal anti-inflammatory meds are actually likely to make this problem worse, and are not usually recommended in treating PTTD), or use ultrasound therapy. Once the inflammation has gone down a bit, your podiatrist may recommend using orthotics (prescription shoe inserts) to support your damaged arch. Ankle braces can also be helpful.
Surgical Treatment
If conservative treatment fails to provide relief of pain and disability then surgery is considered. Numerous factors determine whether a patient is a surgical candidate. They include age, obesity, diabetes, vascular status, and the ability to be compliant with post-operative care. Surgery usually requires a prolonged period of nonweightbearing immobilization. Total recovery ranges from 3 months to one year. Clinical, x-ray, and MRI examination are all used to select the appropriate surgical procedure.
