What must be considered to avoid a mismatch when using TSA glenoses?

The consideration of the recommended humeral head and glenoid sizes is crucial in avoiding a mismatch when using TSA glenoses. This is because the compatibility of the glenoid with the humeral component directly influences the functionality and overall success of the shoulder replacement. If the sizes of the humeral head and glenoid do not correspond properly, it can lead to joint instability, improper range of motion, and possibly premature wear on the implant components. Ensuring that the selected sizes are appropriate helps maintain biomechanical balance, optimize joint performance, and reduce the likelihood of complications post-surgery.

While aspects like the length of the stems, the patient's age and activity level, or the type of anesthesia might impact the surgical procedure and the patient's recovery, they are not directly related to the compatibility of the glenoid and humeral components, which is fundamental in avoiding a mismatch. Thus, focusing on the correct sizing of the components is essential to achieving a successful outcome in total shoulder arthroplasty.
