“…Jones et al [ 28 ] evaluated accuracy and precision in glenoid positioning with a cadaveric study comparing preoperative plan and postoperative TC. They reported an average error from the preoperative plan of 1.9 ± 1.9° for version and 2.4 ± 2.4° for inclination of glenoid component.…”

Introduction One of the main causes of RSA failure is attributable to the malpositioning of the glenoid component. Initial experiences with computer-assisted surgery have shown promising results in increasing the accuracy and repeatability of placement of the glenoid component and screws. The aim of this study was to evaluate the functional clinical results, in terms of joint mobility and pain, by correlating them with intraoperative data regarding the positioning of the glenoid component. The hypothesis was that the lateralization more than 25 mm of the glenosphere can led to better stability of the prosthesis but should pay in term of a reduced range of movement and increased pain. Materials and methods 50 patients were enrolled between October 2018 and May 2022; they underwent RSA implantation assisted by GPS navigation system. Active ROM, ASES score and VAS pain scale were recorded before surgery. Preoperative data about glenoid inclination and version were collected by pre-op X-Rays an CT. Intraoperative data—inclination, version, medialization and lateralization of the glenoid component—were recorded using computer-assisted surgery. 46 patients had been further clinically and radiographically re-evaluated at 3-months, 6-months, 1-year, and 2-years follow-up. Results We found a statistically significant correlation between anteposition and glenosphere lateralization value (DM − 6.057 mm; p = 0.043). Furthermore a statistically significant correlation has been shown between abduction movement and the lateralization value (DM − 7.723 mm; p = 0.015). No other statistically significant associations were found when comparing the values of glenoid inclination and version with the range of motion achieved by the patients after reverse shoulder arthroplasty. Conclusion We observed that the patients with the best anteposition and abduction results had a glenosphere lateralization between 18 and 22 mm. When increasing the lateralization above 22 mm or reducing it below 18 mm, on the other hand, both movements considered decreased their range.

“…Preoperative planning software used with computer navigation or patient-specific guides provides more accurate and reproducible positioning and orientation of the glenoid component in aTSA and rTSA. 7 , 19 , 33 The results of our study demonstrate that glenoids with posterior wear reduce surgeons' ability to reproduce their preoperative plan when not using patient-specific guides or navigation during rTSA, but not aTSA. This is in agreement with some prior studies; glenoid morphology has been shown to have no significant influence on the accuracy of patient-specific guides during aTSA.…”

“…Most patients were female—62.67 and 63.07% for the NAV and CON groups, respectively. Although 70% of the studies 30,32,34,35,37-39 reported the preoperative glenoid morphology according to the Walch original or modified classification 40,41 , no study correlated any reported outcome of interest in reference to the Walch classification.

“…Increased surgical times have been more commonly associated with NAV assistance 14,21,61,62 . However, some authors have shown that following a short learning curve, NAV does not significantly increase surgical time compared with CON methods 32,35 . This is important because longer operative times are known to increase major local complications and the rate of surgical site infection 63 .…”

Background: Glenoid baseplate malpositioning during reverse total shoulder arthroplasty can contribute to perimeter impingement, dislocation, and loosening. Despite advances in preoperative planning, conventional instrumentation may lead to considerable inaccuracy in implant positioning unless patient-specific guides are used. Optical navigation has the potential to improve accuracy and precision when implanting a reverse shoulder arthroplasty baseplate. This systematic review aimed to analyze the most recent evidence on the accuracy and precision of glenoid baseplate positioning using intraoperative navigation and its potential impact on component selection and surgical time. Methods: We conducted a systematic review following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses criteria. The PubMed, Scopus, and EMBASE databases were queried in July 2022 to identify all studies that compared navigation vs. conventional instrumentation for reverse shoulder arthroplasty. Data of deviation from the planned baseplate version and inclination, the use of standard or augmented glenoid components, and surgical time were extracted. Quantitative analysis from the included publications was performed using the inverse-variance approach and Mantel-Haenszel method. Results: Of the 2,048 records identified in the initial query, only 10 articles met the inclusion and exclusion criteria, comprising 667 shoulders that underwent reverse total shoulder arthroplasty. The pooled mean difference (MD) of the deviation from the planned baseplate position for the clinical studies was −0.44 (95% confidence interval [CI], −3.26; p = 0.76; I2 = 36%) for version and −8.75 (95% CI, −16.83 to −0.68; p = 0.02; I2 = 83%) for inclination, both in favor of navigation. The odds ratio of selecting an augmented glenoid component after preoperative planning and navigation-assisted surgery was 8.09 (95% CI, 3.82-17.14; p < 0.00001; I2 = 60%). The average surgical time was 12 minutes longer in the navigation group (MD 12.46, 95% CI, 5.20-19.72; p = 0.0008; I2 = 71%). Conclusions: Preoperative planning integrated with computer-assisted navigation surgery seems to increase the accuracy and precision of glenoid baseplate inclination compared with the preoperatively planned placement during reverse total shoulder arthroplasty. The surgical time and proportion of augmented glenoid components significantly increase when using navigation. However, the clinical impact of these findings on improving prosthesis longevity, complications, and patient functional outcomes is still unknown.
