Eclipse™ Total Shoulder 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°.

With anatomic restoration of the humerus and glenoid, soft-tissue balancing of the rotator cuff is more accurate, allowing for improved functional outcome. Therefore, the Univers Apex OptiFit humeral component was designed to account for common anatomical variations of the proximal humerus and allow the surgeon to adapt the humeral stem and articular surface to the position that best represents the patient’s normal anatomy. Variable adjustments with respect to the inclination angle, version, and head offset can be made intraoperatively with the implant in the humeral canal.&nbsp;
The midrange stem length in combination with the titanium plasma spray optimizes stability and bone preservation1, while the rectangular stem body and removable trunnion optimize revisability. In addition, strategically incorporated suture holes allow for unique subscapularis repair options.

Univers Apex OptiFit™ 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™ II 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™ Apex Total Shoulder System

Stemmed Techniques

The Univers cuff arthropathy humeral head system is intended for hemiarthroplasty applications when treating end-stage rotator cuff arthropathy for which reverse shoulder arthroplasty is not indicated. The implants are designed to articulate with the native glenoid and acromion, allowing for smooth range of motion. The CA humeral heads and instrumentation are compatible with the Univers Apex, Univers II, and Univers fracture humeral implants.

Univers™ Cuff Arthropathy Hemiarthroplasty Technique

Univers™ Cuff Arthropathy Hemiarthroplasty Technique

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.
The system includes:
<ul>
 <li>An intraoperative adjustable humeral head prosthesis for secondary correction of the implant head height in situ.</li>
 <li>A preoperative and intraoperative measure guide to accurately set the humeral head height without need for technically demanding and complicated fracture jigs.</li>
 <li>Lateral fin positions with suture eyelets for anatomic reconstruction of the tuberosities.</li>
 <li>Multiple suture eyelets on the trunnion to prevent secondary displacement of the tuberosities.</li>
 <li>Smooth chamfered dimples in the medial aspect of the humeral stem to allow suture fixation of the tuberosity fragments without causing suture fraying and breakage.</li>
 <li>Variable eccentric adjustment of the humeral head for anatomic reconstruction.</li>
</ul>
