Glenoid Component Placement Assisted by Augmented Reality Through a Head-Mounted Display During Reverse Shoulder...

Area of Science:

• Orthopedic surgery
• Surgical technology
• Medical imaging

Background:

• Accurate component positioning is crucial for successful reverse shoulder arthroplasty outcomes.
• Challenges in glenoid component placement arise in cases of severe scapular deformity or limited visualization.
• Preoperative planning is essential but difficult to translate into surgical practice.

Purpose of the Study:

• To detail the step-by-step utilization of a navigated augmented reality (AR) system for glenoid component placement.
• To demonstrate how AR technology can overcome challenges in achieving precise component positioning.
• To provide a guide for implementing AR in reverse shoulder arthroplasty procedures.

Main Methods:

• Utilized a navigated AR system with a head-mounted display (HMD) for real-time surgical guidance.
• Integrated virtual information of instrument and component position directly into the surgeon's view of the operative field.
• Validated the AR system's efficacy in phantom and cadaveric models for shoulder arthroplasty.

Main Results:

• Navigated AR systems provide real-time virtual information overlaid onto the real world.
• Head-mounted displays (HMDs) enable direct visualization of this guidance during surgery.
• The system aids in overcoming challenges associated with glenoid component positioning, particularly in complex cases.

Conclusions:

• Navigated AR systems offer a viable solution for improving glenoid component positioning in reverse shoulder arthroplasty.
• This technology enhances the translation of preoperative plans into surgical reality.
• AR-assisted surgery holds promise for improving functional outcomes and reducing complications in shoulder arthroplasty.
