Computer-Assisted Planning and Patient-Specific Instrumentation (PSI) in Shoulder Arthroplasty

  • Dragomir Mijic

Accurate glenoid component insertion has been one of the more challenging aspects of shoulder arthroplasty. Computer-assisted virtual planning and patient-specific instrumentation (PSI) can aid surgeons in overcoming this challenge. Recent advances in imaging techniques now allow surgeons to accurately assess 3D anatomy of the glenoid and scapula, while sophisticated 3D software allows simulated implantation of glenoid components as a part of preoperative planning. Numerous studies have demonstrated that the use of patient-specific instrumentation allowed for accurate replication of preoperative plan and significantly improved accuracy of glenoid component position when compared to standard instrumentation. Continued innovation in shoulder arthroplasty will lead to 3D software and PSI better designed to predict and control many intraoperative variables. Decreasing costs and increasing speed of PSI manufacturing will lead to increased availability and utilization that will hopefully translate to improved accuracy of glenoid component implantation and ultimately improved clinical outcomes of shoulder arthroplasty.
