Adult Acquired Flatfoot occurs when the arch of your foot collapses after your skeleton has stopped growing, usually resulting in the foot ?falling? inward with the toes pointing out. This allows
your entire sole to touch the ground when you stand, instead of just the outside area. Arches fall for many reasons, including arthritis, injury to the supporting tendons or bones, nerve problems,
diabetic collapse, pregnancy, aging, and obesity. A fallen arch doesn?t have to be painful-though as it develops and worsens, it can lead to strain and weakness in the feet that could allow for more
uncomfortable foot problems later. Diabetics can develop serious complications from their fallen arches, and need to have their condition evaluated and treated.
Overuse of the posterior tibial tendon is often the cause of PTTD. In fact, the symptoms usually occur after activities that involve the tendon, such as running, walking, hiking, or climbing
Some symptoms of adult acquired flat foot are pain along the inside of the foot and ankle, pain that increases with activity, and difficulty walking for long periods of time. You may experience
difficulty standing, pain on the outside of the ankle, and bony bumps on the top of the foot and inside the foot. You may also have numbness and tingling of the feet and toes (may result from large
bone spurs putting pressure on nerves), swelling, a large bump on the sole of the foot and/or an ulcer (in diabetic patients). Diabetic patients should wear a properly fitting diabetic shoe wear to
prevent these complications from happening.
The diagnosis of posterior tibial tendon dysfunction and AAFD is usually made from a combination of symptoms, physical exam and x-ray imaging. The location of pain, shape of the foot, flexibility of
the hindfoot joints and gait all may help your physician make the diagnosis and also assess how advanced the problem is.
Non surgical Treatment
Because of the progressive nature of PTTD, early treatment is critical. If treated soon enough, symptoms may resolve without the need for surgery and progression of the condition can be stopped. If
left untreated, PTTD may create an extremely flat foot, painful arthritis in the foot and ankle, and will limit your ability to walk, run, and other activities. Your podiatrist may recommend one or
more of these non-surgical treatments to manage your PTTD. Orthotic devices or bracing. To give your arch the support it needs, your foot and ankle surgeon may recommend an ankle brace or a custom
orthotic device that fits into your shoe to support the arch. Immobilization. A short-leg cast or boot may be worn to immobilize the foot and allow the tendon to heal. Physical therapy. Ultrasound
therapy and stretching exercises may help rehabilitate the tendon and muscle following immobilization. Medications. Nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen, help reduce the
pain and inflammation. Shoe modifications. Your foot and ankle surgeon may recommend changes in your footwear.
Good to excellent results for more than 80% of patients have been reported at five years' follow up for the surgical interventions recommended below. However, the postoperative recovery is a lengthy
process, and most surgical procedures require patients to wear a plaster cast for two to three months. Although many patients report that their function is well improved by six months, in our
experience a year is required to recover truly and gain full functional improvement after the surgery. Clearly, some patients are not candidates for such major reconstructive surgery.
