Abstract
A thoracic index is a formula used to qualify or quantify a thoracic deformity and in some cases, to define strategies within treatment. It is also a diagnostic tool used historically to assess the severity of the defect. There is no definition, classification, or consensus in the literature on which thoracic index is the gold standard. There are also no guidelines regarding cut-off values. This chapter is an effort to put all this together, starting by defining thoracic indexes, proposing a classification and describing them in detail for the first time. The main objective is to find out which are the most commonly indexes used by chest wall malformation experts worldwide, and why. For this reason the present chapter includes a web-based survey made to the aforementioned experts in order to review this issue in detail. Since there is currently no thoracic index without limitations, perhaps the perfect index is a mathematical combination of several different indexes. Perhaps it is one single index still to be discovered. This is the first step to search for a universal thoracic index for surgical – decision making.
