AI Article Synopsis
- The study aimed to assess how a software update affected measurements of glenoid inclination, version, and humeral head subluxation using a 3D planning program for shoulder surgeries.
- The analysis involved 76 CT scans from patients who had shoulder replacements, comparing results from the 2018 version of the software to the updated 2020 version.
- The results showed a significant change in glenoid inclination measurements after the update, suggesting surgeons need to critically evaluate data from automated software due to its potential variability.
Article Abstract
Background: The purpose of this study was to evaluate the impact of software updating on measurements of the glenoid inclination and version, along with humeral head subluxation performed by an automated 3D planning program. The hypothesis was that the software update could significantly modify the values of the glenoid inclination and version, as well as of the humeral head subluxation.
Methods: A comprehensive pool of 76 shoulder computed tomography (CT) scans of patients who underwent total shoulder arthroplasty (TSA) or reverse total shoulder arthroplasty (RTSA) were analyzed with the automated program Blueprint in 2018 and again in 2020 after a software update.
Results: A statistically significant difference of 8.1 ± 8.2 and 5.4 ± 7.8 (mean difference of -2.8 ± 5.0, < 0.001) was indeed reached when comparing the mean glenoid inclination achieved with Blueprint 2018 and Blueprint 2020, respectively. The glenoid version, as well as the humeral head subluxation evaluations, were not significantly different between the two software versions, with mean values being -9.4 ± 8.9 and -9.0 ± 7.4 and 60.1 ± 12.6 and 61.8 ± 12.0, respectively ( = 0.708 and = 0.115, respectively). In 22% of CT scans, the software update determined a variation of the glenoid inclination of more than 5° or 10°.
Conclusion: The present study shows the software update of an automated preoperative planning program may significantly modify the values of glenoid inclination. Even though without a significant difference, variations were also found for the glenoid version and humeral head subluxation. Accordingly, these results should further advise surgeons to carefully and critically evaluate data acquired with automated software.

Does Scapular and Thoracic Morphology Affect Latarjet Alpha Angle?

This study aimed to determine the relationship between alpha angle (the angle between the screws and the glenoid) and thoracic diameters in patients undergoing the Latarjet procedure. Defining the relationship between thoracic morphology and alpha angle is aimed at filling the gap in the literature and improving surgical outcomes. This retrospective study analyzed 74 patients who underwent the Latarjet procedure for recurrent anterior shoulder instability between 2022 and 2024.

Scapular morphological attributes show promise as prognostic indicators of retear following rotator cuff repair. Current evaluation techniques using single-slice magnetic-resonance imaging (MRI) are, however, prone to error, while more accurate computed tomography (CT)-based three-dimensional techniques, are limited by cost and radiation exposure. In this study we propose deep learning-based methods that enable automatic scapular morphological analysis from diagnostic MRI despite the anisotropic resolution and reduced field of view, compared to CT.

- The optimal treatment for B2 glenoid morphology in young, active osteoarthritis patients is debated, with various options like hemiarthroplasty, total shoulder arthroplasty (TSA), and reverse TSA available, each having pros and cons.
- Eccentric glenoid reaming can be effective but risks damaging the bone structure, potentially complicating future surgeries, while bone grafting, though beneficial for some, comes with high complication rates.
- Reverse TSA offers a more stable alternative when correcting version and inclination proves difficult, as it adapts better to glenoid deformities and maintains functionality with reduced bone stock.

Objective: To investigate the effect of glenohumeral bone structure on anterior shoulder instability by three-dimensional CT reconstruction.
Methods: The clinical data of 48 patients with unilateral anterior shoulder dislocation (instability group) and 46 patients without shoulder joint disease (control group) admitted between February 2012 and January 2024 were retrospectively analyzed. There was no significant difference in gender and side between the two groups ( >0.

Introduction The aim of this study was to investigate whether the morphology of the acromion and the inclination of the glenoid are associated with the risk of supraspinatus (SSP) tendon ruptures. Materials and methods A total of 106 patients were enrolled in this study between August 2012 and February 2014, including 55 symptomatic patients with an SSP tendon rupture (ruptured group) and 51 patients with an intact SSP (control group). MRI of the shoulder was performed for all patients in both groups.
