Patomechanics of the digital deformity and distribution of the pressures in stance phase

Abstract

There are three patomechanics models of digital deformity. Flexor stabilization model, flexor replacement model and extensor replacement model. Each is produced in a given phase of the process of the march. Plantar pressures are burdens which receives the foot when in contact with the ground. Materials and methods: 25 participants, 15 are of flexor stabilization studing 30 feet, 9 by extensor replacement estudiandose 18 feet and 1 for flexor replacement studing 1 foot. Plantar pressures were measured in supporting medium with a platform of pressure. Results: In the flexor stabilization model the pressure of 2º and 3ºmetatarsals are greater than rest of metatarsals, and there were no significant differences between 2º and 3º, and 1º and 4º metatarsals. The same model succeeded in extensor replacement. The model replacement flexora not perform any evidence because the sample was not representative. Conclusion: metatarsal what else are receiving pressure have relation with toes affected with digital deformity.
