Arthrex Total Shoulder Arthroplasty (TSA) IOT Practice Exam – Prep & Study Guide

The Univers FX stems are notably constructed from titanium, which is a significant design feature due to the material's favorable properties. Titanium is well-regarded in orthopedic implants for its excellent strength-to-weight ratio, biocompatibility, and resistance to corrosion. These characteristics promote healthy integration with the bone and minimize adverse reactions within the body, leading to improved outcomes for patients undergoing shoulder arthroplasty. Moreover, the use of titanium allows for longer implant life and durability, which is crucial for the longevity of the shoulder replacement.

The other options do not correctly reflect the prominent design aspects of the Univers FX stems. For instance, while there are cemented and uncemented options available, the design is not limited to just cemented models. Additionally, biodegradable materials are not suitable for permanent implants such as those used in TSA as they must provide long-lasting support. Lastly, while adjustable neck angles can be a feature in some shoulder systems, the Univers FX specifically highlights its titanium construction as a key advantage.
