Development of Point Contact Fixator

Abstract

Abstract:

In the field of fracture treatment, the Point Contact Fixator (PC-Fix) is a novel internal fixation method that has attracted much attention, completely overturning the concept and approach of traditional fracture internal fixation methods. PC-Fix was designed and developed by Professor Perren and his team as early as the 1990s, and its main features are point contact and locked fixation, with the aim of protecting the blood supply in the fracture area. PC-Fix solves the problems of blood supply damage caused by traditional compression plates in contact with bone and stress shielding, and the fixation method has changed from "compression fixation" to "locked fixation", which is the prototype of locked plates. Moreover, PC-Fix has been verified to have excellent performance in protecting blood supply and fracture fixation stability in both animal experiments and clinical research. This review retrospectively examines the development history of PC-Fix, summarizes its design features, and aims to provide ideas and references for the design of future internal fixation systems.
