Arthrex Total Shoulder Arthroplasty (TSA) IOT Practice Test

One key feature of the Univers II and Apex Total Shoulder Arthroplasty systems is their inclination variability, which ranges from 125 to 140 degrees. This feature is significant as it allows surgeons to customize the implant placement according to the unique anatomical needs of the patient, thereby optimizing joint stability and range of motion post-surgery. Having variability in inclination can help address varying degrees of glenoid retroversion and facilitate the alignment of the components in relation to the patient's shoulder anatomy. This adaptability contributes to improved clinical outcomes and can enhance the overall durability and function of the shoulder joint after the procedure. The other features, while possibly important in other contexts or systems, do not offer the same level of customization with respect to the positioning of the humeral component, which is crucial in achieving the desired outcomes in shoulder arthroplasty.
