Medical science is an ever evolving science. Human body remains same, but our understanding of it changes, and hence our methods of treating patients. Technology has played a vital role in development of orthopaedics in particular. What most important is that over the years these new technologies and methods have percolated down to the remotest areas of the developing world. It is with this perspective that updating even a basic book such as this one has become necessary. Our mission is aspiring to serve Humanity: "We can throw stones, complain about them, stumble on them, or climb over them and build with them".
