Definitions

  • the osteosynthesis plate 5 consists of a thermoplastic material which can be deformed at a temperature slightly above body temperature, but which is dimensionally stable at body temperature.
  • a material can be, for example, a modified methacrylate, in particular a polyethyl methacrylate, which can be deformed at a temperature of approximately 50 ° C.
  • Reinforcing fibers 9 are embedded in the plastic mass, for example continuous carbon fibers, which on the one hand reinforce the osteosynthesis.

Abstract

Ce procédé d'adaptation de la forme de plaques d'ostéosynthèse (5) en matière synthétique thermoplastique, où sont noyées des fibres de renforcement (9), consiste à chauffer la matière synthétique thermoplastique pour pouvoir l'ajuster même à l'intérieur du corps et sans modifier la plaque d'ostéosynthèse (5). A cet effet, on soumet la plaque d'ostéosynthèse (5) à un rayonnement électromagnétique et l'on réchauffe la matière synthétique entourant les fibres (9) à l'aide de ce rayonnement transformé en chaleur dans les fibres de renforcement (9), jusqu'à ce que cette matière puisse être déformée.
