Introduction to Deformity Analysis and Planning
Deformity can be simply described as deviation from normal anatomy. This can be in the form of angulation, translation, rotation or length. The purpose of analysis is to report the magnitude and direction of a deformity or combination of deformities in a patient. To achieve this goal, we should have the standard values of the normal anatomy and a standard radiologic survey to work on. This chapter covers the description and basic components of a deformity and principles to obtain appropriate radiologic imaging for analysis. Details of each deformity component and methods for their correction will be discussed in the following chapters.
