Evaluating the results of long tubular bone distraction with an advanced rod monolateral external fixator for achondroplasia

Abstract The work aimed to evaluate the effectiveness of the developed distraction system based on the rod external monolateral fixation mechanisms by comparing it with the classical technique of long tubular bones distraction based on the circular multi-axial system. The study included patients wit...
