Arthrex Total Shoulder Arthroplasty (TSA) IOT Practice Test

The statement regarding the comparison between standard glenoid components and the vault lock that is accurate concerns the differences in the radius of curvature (ROC). In the case of the vault lock, it is designed with a specific anatomical consideration that differs from the standard glenoid components, providing unique benefits in terms of articulation and fitting. This difference is essential because it directly impacts how the components work together, promoting a more favorable outcome for shoulder function and stability after total shoulder arthroplasty.

The other statements do not hold true in the same way. For instance, while radio markers can be found in various components, the specifics about their location and application might differ between standard glenoid and vault lock components. Furthermore, the trial components are not the same for both types; each has been specially designed to align with its respective system and functionality. These distinctions play a crucial role in the surgical process and the overall effectiveness of the implant.
