Arthrex Total Shoulder Arthroplasty (TSA) IOT Practice Test

The glenoid component orientation is critical in total shoulder arthroplasty (TSA) because it directly influences the functionality of the shoulder joint post-surgery. Proper placement of the glenoid component optimizes its angle and position, which is essential for achieving a stable and well-functioning joint. An accurate orientation helps in maintaining the correct alignment, minimizing the risk of dislocation, and ensuring that the mechanics of the shoulder joint are preserved, facilitating a more natural range of motion during activities.

When the glenoid component is correctly oriented, it can better accommodate the forces exerted during shoulder movement, leading to improved joint kinematics. This not only enhances the patient's ability to perform daily activities but also contributes to overall satisfaction with the surgical outcome. Thus, the emphasis on optimizing function through the proper orientation of the glenoid component is paramount in TSA procedures.
