ABSTRACT

The insufficiency of the posterior tibial tendon is the most common acquired cause of pain related to valgus flatfoot deformity in adults. The acquired flatfoot adult is a very painful symptomatic deformity resulting from a gradual stretching (attenuation) of the posterior tibial tendon and ligaments that support the arch of the foot. The progressive pain acquired flatfoot adult affects four times more women than men. Some factors that contribute to increased risk of acquired flatfoot in adults, are diabetes, hypertension and obesity. It is thought that the combination of the following events is the cause of acquired flatfoot adult. Johnson Strom classification modified by Mayerson evaluates in 4 stages. This study was divided into 3 stages: Stage 1: Dissection and three-dimensional analysis of the tendon, Step 2: Application of tools bioengineering to determine the causes of rupture of the tibial tendon: Stage 3: Evaluation of 24 patients with flatfoot disease valgus for describe the deformity.


Key words: Flat foot disease, tibial posterior insufficiency, numeric simulation, tridimensional, cadaveric.
