Cast index in predicting outcome of pediatric forearm fractures

Abstract

Introduction: Prediction of Re-displacement of pediatric forearm fractures would be a boon for orthopaedic surgeons treating them conservatively. Cast index (CI), described by Chess et al. is calculated by measuring the internal antero-posterior (AP) diameter of the cast (excluding padding) at the level of the fracture and dividing it by the internal lateral diameter of the cast (excluding padding) which could be used as a tool to predict the re-displacement of fracture if it is maintao 0.8 were more likely toget re-displaced than with
