Univers^™ Fracture Technique

The Univers fracture prosthesis is used to treat comminuted fractures of the proximal humerus, humeral head fractures, displaced 3- or 4-part proximal humerus fractures, avascular necrosis of the humeral head, and fractures of the anatomic neck. This prosthesis is designed for cemented or cementless use. The unique design of the implant and instrumentation, in combination with a straightforward, reproducible protocol for accurately reducing and repairing the tuberosity, helps address issues relating to stabilization of the humeral prosthesis and accurate positioning of the humeral head.

Features and Benefits

• Suture fixation: Multiple suture eyelets on the trunnion and lateral fin for anatomic reconstruction of the tuberosity
• Head height guides: A preoperative and intraoperative measuring guide for accurately setting the humeral head height, without technically demanding and complicated fracture jigs
• Intraoperative adjustable humeral head prosthesis for secondary correction of the implant head height in situ
• Lateral fin positions with suture eyelets for anatomic reconstruction of the tuberosities
• Multiple suture eyelets on the trunion to prevent secondary displacement of the tuberosities
• Smooth, chamfered dimples in the medial aspect of the humeral stem allow suture fixation of the tuberosity fragments without causing suture fraying and breakage
• Variable eccentric adjustment of the humeral head for anatomic reconstruction
