Novel combination of reverse engineering and vapid prototyping in medicine

The technologies of reverse engineering and rapid prototyping are emerging as useful new tools in medicine. One application is of particular interest in orthopaedic, dental and reconstructive surgery. It involves the imaging, modelling and replication las a physical model) of a patient's bone struct ure. The models can be viewed and physically handled before surgery, which is of great benefit in evaluation of the procedure and implant fit in diffi cult cases. The technology promises lessened risk to the patient and reduce d cost through saving in theatre time. A case study is presented, involving hip replacement in a patient who had experienced severe bone loss through osteoporosis. Such applications are a further step towards the development of a new generation of customized bone implants.
