What is the head height adjustment range for Univers FX stems?

The head height adjustment range for Univers FX stems is indeed 7.5cm inferior (INF) or 7.5cm superior (SUP). This range is significant because it allows for precise customization of the stem's positioning in relation to the patient's anatomy.

Adjusting the head height within this range can help achieve optimal joint mechanics and, consequently, better functional outcomes in shoulder arthroplasty. By allowing adjustments both inferiorly and superiorly, surgeons can tailor the implant to fit various patient anatomies, enhancing stability and range of motion while minimizing the risk of complications such as impingement or dislocation.

Other ranges provided in the choices do not offer the flexibility necessary for accommodating the diverse anatomical variations encountered in patients undergoing total shoulder arthroplasty, which further highlights why 7.5cm INF or 7.5cm SUP is crucial for achieving individualized and effective implant positioning.
