摘要
在骨折治疗领域,点接触固定器(PC-Fix)是一种备受关注的新型内固定方法,它的出现彻底颠覆了传统骨折内固定方法的理念和方式。PC-Fix是早在20世纪90年代被Perren教授及其团队设计研发,其主要特点有点接触和锁定固定两个方面,其目的主要是为了保护骨折区域血运。PC-Fix解决了传统加压钢板与骨接触所造成的血运损伤以及应力遮挡问题,固定方式也由“加压固定”改为“锁定固定”,是锁定钢板的雏形。并且PC-Fix在保护血运和骨折固定稳定性方面的优异性,在动物实验和临床研究中也都得到了验证。本篇综述回顾PC-Fix的研发历史,总结PC-Fix的设计特点,以期为未来内固定系统的设计提供思路与借鉴。
In the field of fracture treatment,the Point Contact Fixator(PC-Fix)is a novel internal fix-ation method that has attracted much attention,completely overturning the concept and approach of tradition-al 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"com-pression 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 fixa-tion systems.
