“…Hierbei wurden die genauesten Ergebnisse der Positionierung mittels einer Kombination aus einer präoperativen 3-D-Planung und einem an die jeweilige Planung angepassten PSI erreicht [61]. Während diese Daten von der Mehrheit vergleichbarer Studien aus den vergangenen Jahren bestätigt wurden [62,63,64], konnten erste retrospektive klinische Studien keinen Einfluss auf das kurzzeitige klinische Outcome trotz verbesserter Glenoidpositionierung aufzeigen [65,66].…”

“…Malpositioning of the glenoid can further be prevented with patient-specific instrumentation (PSI) guides, which have been shown to improve the radiological outcomes compared to standard instrumentation with 3D preoperative planning [11]. However, PSI guides, which are individually 3D-printed templates for the central K-wire application of the glenoid, did not impact clinical outcomes compared to 3D planning alone [12,13]. Furthermore, the implementation of new techniques like augmented reality can help to access these three-dimensional plans intraoperatively at any time using virtual reality goggles or displays and, therefore, increase intraoperative accuracy.…”

Background: Reversed total shoulder arthroplasty (RTSA) is an established surgery for many pathologies of the shoulder and the demand continues to rise with an aging population. Preoperative planning is mandatory to support the surgeon’s understanding of the patient’s individual anatomy and, therefore, is crucial for the patient’s outcome. Methods: In this observational study, we identified 30 patients who underwent RTSA with two- and three-dimensional preoperative planning. Each patient underwent new two-dimensional planning from a medical student and an orthopedic resident as well as through a mid-volume and high-volume shoulder surgeon, which was repeated after a minimum of 4 weeks. The intra- and interobserver reliability was then analyzed and compared to the 3D planning and the implanted prosthesis. The evaluated parameters were the size of the pegged glenoid baseplate, glenosphere, and humeral short stem. Results: The inter-rater reliability showed higher deviations in all four raters compared to the 3D planning of the base plate, glenosphere, and shaft. The intra-rater reliability showed a better correlation in more experienced raters, especially in the planning of the shaft. Conclusions: Our study shows that 3D planning is more accurate than traditional planning on plain X-rays, despite experienced shoulder surgeons showing better results in 2D planning than inexperienced ones.

“…Both groups showed similar improvements in patient-reported outcomes. While the SG group demonstrated better improvements in certain range of motion measures, the PSI group exhibited greater abduction and external rotation strength ( 49 ). Additionally, the use of PSI is notably beneficial in cases with glenoid bone loss.…”

Accurate component placement in shoulder arthroplasty is crucial for avoiding complications, achieving superior biomechanical performance and optimizing functional outcomes. Shoulder and elbow surgeons have explored various methods to improve surgical understanding and precise execution including preoperative planning with 3D computed tomography (CT), patient-specific instrumentation (PSI), intraoperative navigation, and mixed reality (MR). 3D preoperative planning facilitated by CT scans and advanced software, enhances surgical precision, influences decision-making for implant types and approaches, reduces errors in guide pin placement, and contributes to cost-effectiveness. Navigation demonstrates benefits in reducing malpositioning, optimizing baseplate stability, improving humeral cut, and potentially conserving bone stock, although challenges such as varied operating times and costs warrant further investigation. The personalized patient care and enhanced operational efficiency associated with PSI are not only attractive for achieving desired component positions but also hold promise for improved outcomes in complex cases involving glenoid bone loss. Augmented reality (AR) and virtual reality (VR) technologies play a pivotal role in reshaping shoulder arthroplasty. They offer benefits in preoperative planning, intraoperative guidance, and interactive surgery. Studies demonstrate their effectiveness in AR-guided guidewire placement, providing real-time surgical advice during reverse total shoulder arthroplasty (RTSA). Additionally, these technologies show promise in orthopedic training, delivering superior realism and accelerating learning compared to conventional methods.
