This textbook offers new insights into the use of computer assisted surgery and minimally invasive surgery in orthopaedic surgery. A comprehensive presentation of scientific work and clinical experience is included encompassing areas of spine, trauma, sports and reconstructive surgery. We have added sections that discuss minimally invasive surgery, as we believe CAS will be an enabling technology for these more challenging approaches by providing a virtual digital "surgical exposure". Finally, we have explored areas of new endeavor that may not have current applications. We believe that this textbook will be attractive to those new to this area as well as providing an update for existing users.
