Treatments And CausesOverview
For many adults, years of wear and tear on the feet can lead to a gradual and potentially debilitating collapse of the arch. However, a new treatment approach based on early surgical intervention is achieving a high rate of longterm success. Based on results of clinical studies of adults with flat feet, we now believe that reconstructive surgery in the early stages of the condition can prevent complications later on. Left untreated, the arch eventually will collapse, causing debilitating arthritis in the foot and ankle. At this end stage, surgical fusions are often required to stabilize the foot.
Women are affected by Adult Acquired Flatfoot four times more frequently than men. Adult Flatfoot generally occurs in middle to older age people. Most people who acquire the condition already have flat feet. One arch begins to flatten more, then pain and swelling develop on the inside of the ankle. This condition generally affects only one foot. It is unclear why women are affected more often than men. But factors that may increase your risk of Adult Flatfoot include diabetes, hypertension, and obesity.
Pain and swelling around the inside aspect of the ankle initially. Later, the arch of the foot may fall (foot becomes flat), this change leads to walking to become difficult and painful, as well as standing for long periods. As the flat foot becomes established, pain may progress to the outer part of the ankle. Eventually, arthritis may develop.
In the early stages of dysfunction of the posterior tibial tendon, most of the discomfort is located medially along the course of the tendon and the patient reports fatigue and aching on the plantar-medial aspect of the foot and ankle. Swelling is common if the dysfunction is associated with tenosynovitis. As dysfunction of the tendon progresses, maximum pain occurs laterally in the sinus tarsi because of impingement of the fibula against the calcaneus. With increasing deformity, patients report that the shape of the foot changes and that it becomes increasingly difficult to wear shoes. Many patients no longer report pain in the medial part of the foot and ankle after a complete rupture of the posterior tibial tendon has occurred; instead, the pain is located laterally. If a fixed deformity has not occurred, the patient may report that standing or walking with the hindfoot slightly inverted alleviates the lateral impingement and relieves the pain in the lateral part of the foot.
Non surgical Treatment
Treatment of Adult Acquired Flatfoot Deformity depends on the stage of progression, as mentioned above paragraphs. Below we will outline a variety of different treatment options available. Orthotics or bracing. To give your foot the arch the support it needs, your podiatrist or foot specialist may provide you with over the counter brace or a custom orthotic device that fits your shoe. Casting. In some cases, a cast or boot is worn to stabilize the foot and to give the tendon time to heal. Physiotherapy. Ultrasound treatments and exercises may help rehab the tendon and muscles. Medications. Over-the-counter (NSAIDS) such as ibuprofen can help reduce pain, inflammation and swelling associated with AAFD. Shoe Gear. Your podiatrist may suggest changes with your shoes you are wearing and inserts you need in your shoe to help support your arch.
If initial conservative therapy of posterior tibial tendon insufficiency fails, surgical treatment is considered. Operative treatment of stage 1 disease involves release of the tendon sheath, tenosynovectomy, debridement of the tendon with excision of flap tears, and repair of longitudinal tears. A short-leg walking cast is worn for 3 weeks postoperatively. Teasdall and Johnson reported complete relief of pain in 74% of 14 patients undergoing this treatment regimen for stage 1 disease. Surgical debridement of tenosynovitis in early stages is believed to possibly prevent progression of disease to later stages of dysfunction.
