Univers™ Apex Total Shoulder System
The Univers Apex system represents the evolution of Arthrex total shoulder arthroplasty systems. While maintaining all of the in situ variable adjustment capabilities of the Univers II total shoulder system (inclination, version, head offset), the Apex introduces advanced features important in the treatment of all total shoulder patients. The reduced diaphyseal stem length, rectangular stem body, and removable trunnion optimize stem removal and therefore revisability. In addition, strategically incorporated suture holes allow for unique subscapularis repair options. The system is compatible with Univers VaultLock®, pegged, and keeled glenoid systems, the Univeral Glenoid™ convertible baseplate with polyethelene inlays as well as with the Univers II humeral head options. In keeping with the Arthrex focus on intraoperative adaptability, the Apex restores normal patient glenohumeral anatomy in a stable, press-fit solution while allowing for bone-conserving stem revision.
Univers™ II Total Shoulder System
The Univers II humeral component was designed to account for commonly encountered anatomical variations of the proximal humerus. Variable adjustment with respect to the inclination angle, version, and head offset is critical to reconstruction of the proximal humerus. The simplified design of the Univers II humeral component enables for adapting the humeral stem and articular surface to the position that best represents the patient’s normal anatomy. Implant adjustments can be made intraoperatively within the humeral canal. This unique feature allows more accurate recreation of the normal anatomical relationships of the shoulder joint. With anatomic restoration of the humerus and glenoid, soft-tissue balancing of the rotator cuff is more accurate, allowing for improved functional outcome.1
Univers™ Fracture Stems and Hemi Systems
Reconstruction of proximal humerus fractures is often complicated by the loss of anatomic orientation features and the inability to adequately reduce and securely fix the displaced tuberosity fragments. With its uniquely designed implant and instrumentation, the Univers Shoulder Fracture System addresses issues relating to stabilizing the humeral prosthesis and accurately positioning the humeral head. Accurately reduce and fix the tuberosities with this system's straightforward, reproducible protocol.
Univers VaultLock® Glenoid System
Univers VaultLock® glenoids are compatible with Eclipse™, Univers™ II, and Apex shoulder systems. These glenoids feature a fluted central peg for immediate fixation and bony ingrowth, variable backside radius of curvature for conserving subchondral bone, and streamlined instrumentation for inline preparation. Univers VaultLock glenoids are available in four sizes and augmented options of 15° and 25°.
