Computer-guided total hip arthroplasty

Abstract

Computer-assisted surgery in total hip replacement has proven to be better technology for achieving precision for implant placement. Variables that may be improved include leg length determination, appropriate anatomical offset, pelvic tilt, and appropriate version of the implants. This guidance is valuable for use in robotic applications and with minimally invasive operations. Recent meta-analysis studies have demonstrated these improvements over conventional methods relying on conventional instrumentation. Newer technologies include the use of accelerometers and intraoperative computed tomography for automated registration, which reduce drawbacks of inconvenience and complexity of the technology.
