Medical science is an ever evolving science. Human body remains the same, but our understanding of it changes and hence our methods of treating patients. Technology has played a vital role in the 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 such a basic book as this one has become necessary. Our mission is aspiring to serve Humanity: "We can throw stones, complain out them, stumble on them or climb over them and build with them".
