“…A current clinical application of Nashikkar in 60 subjects also shows the superiority of NAV. The deviation from the planning in the navigation group was 0.2° ± 4.8° and 1.4° ± 2.8° for version and inclination, respectively [ 19 ].…”

Background Accurate glenoid positioning in reverse total shoulder arthroplasty (RSA) is important to achieve satisfying functional outcome and prosthesis longevity. Optimal component placement can be challenging, especially in severe glenoid deformities. The use of patient-specific instruments (PSI) and 3D computer-assisted optical tracking navigation (NAV) are already established methods to improve surgical precision. Augmented reality technology (AR) promises similar results at low cost and ease of use. With AR, the planned component placement can be superimposed to the surgical situs and shown directly in the operating field using a head mounted display. We introduce a new navigation technique using AR via head mounted display for surgical navigation in this feasibility study, aiming to improve and enhance the surgical planning. Methods 3D surface models of ten human scapulae were printed from computed tomography (CT) data of cadaver scapulae. Guidewire positioning of the central back of the glenoid baseplate was planned with a dedicated computer software. A hologram of the planned guidewire with dynamic navigation was then projected onto the 3D-created models of the cadaver shoulders. The registration of the plan to the anatomy was realized by digitizing the glenoid surface and the base of the coracoid with optical tracking using a fiducial marker. After navigated placement of the central guidewires, another CT imaging was recorded, and the 3D model was superimposed with the preoperative planning to analyze the deviation from the planned and executed central guides trajectory and entry point. Results The mean deviation of the ten placed guidewires from the planned trajectory was 2.7° ± 1.3° (95% CI 1.9°; 3.6°). The mean deviation to the planned entry point of the ten placed guidewires measured 2.3 mm ± 1.1 mm (95% CI 1.5 mm; 3.1 mm). Conclusion AR may be a promising new technology for highly precise surgical execution of 3D preoperative planning in RSA.

“…However, prior studies have validated the accuracy of this guided technology, and thus, our findings are expected to appropriately predict final implant position. 25 Finally, this study did not evaluate subjective or objective clinical outcomes; therefore, we remain unable to fully assess the clinical benefit of intraoperative guidance on either patient-reported outcomes or implant survival.…”

“… 17 Regardless of glenoid morphology, routine use of computer navigation may improve component positioning; Nashikkar et al found that postoperative alignment of glenoid components for patients undergoing aTSA and rTSA with computer navigation was within 5° of the plan for 82% of cases for version and 76% of cases for inclination. 25 The use of computer navigation or patient-specific guides in addition to preoperative planning may substantially improve the surgeons' accuracy when placing the glenoid component, especially in patients with severe posterior glenoid bone loss undergoing rTSA.…”

“… 9 Recent computer-assisted surgical techniques such as 3-dimensional planning software, patient-specific guides, and navigation systems have been developed for shoulder arthroplasty. 8 , 11 , 13 , 23 Previous studies have shown that the use of a navigation system reduces the average deviation of postoperative glenoid component positioning. 11 , 13 Similarly, our treatment of this patient involved accurate component placement using the navigation system as planned preoperatively.…”
