In this very direction, the Kurgan surgeon GA Ilizarov introduced his technique for tackling various problems and one of them has been for the correction of fixed deformity. The principle behind the Ilizarov technique has great depth. However, against the speed with which the Ilizarov technique was accepted all over the world, its decline unfortunately is also being palpably observed. There can be several reasons but its overuse, uncalculated use, misuse, and underuse have a definite role to play for its decline. And nonetheless, the improper passing of K-wire, injudicious selection of point of entry of wires, and improper placement of rings have a definite role to play in bringing disrepute to the Ilizarov technique. Let us not blame the young enthusiastic surgeons who want to master any technology in minimum time and effort. We feel that there is hardly any monograph detailing the basics of the Ilizarov technique, which includes acquaintance with the hardware, proper selection of patient, pinpointing the placement of the K-wires and the direction of the wire advancement. Another disadvantage is the steep learning curve, so that in most situations successful management of complex deformities can be achieved only after years of experience. The biomechanics itself is a tough subject and we want to avoid intricacies of the biomechanics in our practical life. However, the understanding of the basic kinematics, anatomical localization of the suitable points, and basic physiology of execution of function are mandatory before attempting to master any technique. We have tried to tackle the above problems in a lucid and descriptive manner, so that this manual may be useful even to the Preface beginners, who want to know, learn, execute, and get effective result after the use of the Ilizarov technique. We all want to put our best to make this monograph acceptable by all; however, there may be many shortcomings for which apology is solicited. In preparing this monograph, we have consulted many books and journals, derived in ideas and inspiration, and have been educated through different sources. However, we are particularly indebted to the books given in bibliography, which we have consulted several times. We have no hesitation in giving full credit to these sources.
