THE TREATMENT OF INFECTED NON UNION OF LONG BONES USING THE TWO STAGED MASQUELET TECHNIQUE
Journal Title: INTERNATIONAL JOURNAL OF ADVANCES IN ORTHOPAEDICS - Year 2018, Vol 1, Issue 3
Abstract
INTRODUCTION: A non-union exists when repair is not complete within the period expected for aspecic fracture and when cellular activity at the fracture site ceases and there isno visible progressive signs of healing for 3 consecutive months.[1,2] According to American Food and Drug Administration, a non-union is established when a minimum of 9 months has elapsed since injury and the fracture shows no visible progressive signs of healing for three months.[3] Delayed union, nonunion and pseudoarthrosis represent part of the spectrum of bone repair. [3,4] The incidence and prevalence of non-union vary signicantly based on the anatomic region and the criteria used to dene non-union. It has been estimated that 100,000 fractures go on to non-union each year in the USA.[5,6] Weber introduced a classication system based on biological activity at the fracture site which also facilitates treatment decisions.[7] The Paley classication specically addresses tibial nonunion. It considers bone loss, fracture site mobility, angular deformities and overall tibial length.[8] The Calori Non-union Scoring System (NUSS)[9] has recently been developed to assist surgeons with the complex analysis of non-union surgery. It uses the 'Diamond Concept' where multiple elements are considered in non-unionmanagement, including the cellular environment, the growth factors, the bonematrix and the mechanical stability.
