Relationship between digital deformities and the pathophysiologic of the digital deformity

Abstract

Introduction: There are three patomechanics models of digital deformity. Flexor stabilization model,flexor rlepacement 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: 23 participants, 14 are of flexor stabilization studing 22 feet, 8 by extensor replacement estudiandose 13 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 y 3º, y 1º y 4º metatarsals. The same model succeeded in extensor replacement and there were no significant differences between 2º and 3º, and 1º and 4º metatarsals. 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.
