Principles of Deformity Correction is a comprehensive text on the analysis, planning, and treatment of lower limb deformities in an accessible and instructive format. It teaches the analysis, planning, and methods of deformity correction. A foundation of understanding normal alignment is presented, using new nomenclature that is easy to remember and can even be derived without memorization. The work offers detailed information on deformities and malalignment, radiographic assessment, mechanical and anatomic axis planning, osteotomies, and hardware considerations. The book is extensively illustrated to avoid confusion and to leave little to the imagination. The planning is further facilitated via an exercise workbook and an animated CD-ROM which are available separately. The methods taught are simple and intuitive and require little memorization. This book is of equal interest to pediatric and adult orthopaedic surgeons.
