What is the neck-shaft angle range for Univers II and Apex?

In the context of total shoulder arthroplasty, the neck-shaft angle is a crucial measurement that influences the biomechanics of the shoulder joint and the overall outcome of the surgery. For the Univers II and Apex implant systems, the neck-shaft angle range is specifically designed to optimize glenohumeral mechanics and accommodate the anatomical variations of the humeral head.

The correct range of 125-140 degrees for these systems reflects an angle that supports optimal range of motion, stability, and load distribution across the shoulder joint. This range also promotes greater compatibility with the natural shoulder anatomy, which is essential for restoring normal function post-surgery.

Understanding this neck-shaft angle range is key for orthopedic surgeons when planning and executing a total shoulder arthroplasty, as it directly affects implant positioning and patient outcomes. It is important to choose solutions within this specific range to ensure effective stabilization and movement capabilities in patients undergoing shoulder reconstruction.
