DESIGN AND FABRICATION OF AN OPERATING ROOM COMPUTER ASSISTED ORTHOPAEDIC HIP SURGERY ARTIFACT

摘要

Hundreds of thousands of joint arthroplasty operations are performed throughout the world every year, providing life saving relief from pain and return of mobility to the majority of the individuals who have this treatment. Clinical studies have shown that improper position and orientation of the joint implants can result in accelerated rates of failure, less than satisfactory mobility and even joint dislocation or impingement. Computer Assisted Surgery (CAS) systems have been developed in order to advise the surgeon inside the operating room on the proper positioning and orientation of tools and implants during such operations. The objective of the work described in this paper was to develop a simple, lightweight, easy to use operating room high precision artifact (phantom), which can be used at the beginning of orthopaedic hip operations for a quick performance test of most CAS systems.
