POLYMER CEMENTS USED FOR FIXING PROSTHESES, FOR BONE REPAIR AND FOR VERTEBROPLASTY, AND OBTAINED FROM LIQUID SINGLE-PHASE FORMULATIONS

摘要

The invention relates to a process for preparing cements used for reparative or reconstructive bone surgery, in particular for fixing prostheses, for bone repair and for vertebroplasty, and obtained from liquid single-phase formulations. It also relates to the cements prepared from these single-phase formulations and to a device for injecting them.

1. Method for preparing polymer cements for reparative surgery or for bone reconstruction, comprising bringing a liquid single-phase formulation, said formulation comprising a liquid phase containing at least one polymer or copolymer in solution or in suspension in at least one monomer, and at least one activator of polymerization, into contact with an initiator of radical polymerization deposited in the form of a thin layer or film on a support.
