What is the primary goal of the TSA stem?

The primary goal of the TSA stem is to provide anatomic humeral head replacement. This is essential in total shoulder arthroplasty, as the procedure aims to restore the natural biomechanics of the shoulder joint. The anatomic design of the stem allows for proper alignment and positioning of the humeral head, which is critical for optimal function and range of motion post-surgery. Achieving an anatomic fit helps to ensure better joint stability and enhances the overall outcomes of the procedure, allowing patients to regain shoulder function effectively.

Other considerations, such as facilitating easier surgeries, reducing the weight of the implant, and improving skin closure techniques, are certainly important in the overall surgical process or implant design. However, they do not encapsulate the primary intent of the TSA stem, which is centered around replicating the native anatomy to promote better functional restoration of the shoulder joint.
