The Laser OrthoScope is designed for the automated precision removal of residual polymethylmethacrylate (PMMA) bone cement encountered during revision arthroplasty. The existing technology for the removal of PMMA consists of manual tools and high-speed drills that are associated with complex, protracted surgical operations and high patient morbidity.The purpose of this project is to develop the Laser OrthoScope and to demonstrate its efficacy for the removal of PMMA in a realistic model. This system is designed to be cost effective, easy to operate, and efficient. By incorporating an intraoperative computer-automated laser guidance system, state-of-the-art video imaging, and a closed surgical field cooled by nitrogen gas, the Laser OrthoScope system will offer the reconstructive orthopedic surgeon the next generation of revision arthroplasty equipment.
Anticipated Results:Over 400,000 total hip arthroplasties are performed per year worldwide. The projected number of revision arthroplasties in the United States is 20,000 to 30,000 annually. It has been projected that a 16.8 percent growth will occur per year in the joint prosthetic industry. The Laser OrthoScope could supplant present instrumentation used in revision arthroplasty.National Institute of Arthritis And Musculoskeletal And Skin Diseases
