Zimmer Biomet has announced plans for the broad commercial launch of the Z1 Femoral Hip System (Z1 System) for total hip arthroplasty at the 2024 annual meeting of the American Association of Hip and Knee Surgeons (AAHKS). The Z1 Femoral Hip System is a triple-taper femoral system that pairs with the company’s G7 Acetabular System to provide surgeons with a versatile, streamlined, and efficient total hip arthroplasty solution. 

The Z1 System is tapered in three planes and is designed to provide initial axial and rotational stability and long-term stability across a range of femoral anatomies. It is offered with a single streamlined instrument tray. The Z1 System minimizes the instrument footprint and reduces the processing and sterilization burden. The system includes collared and collarless options for cementless applications and offers three distinct neck options to manage a variety of patient anatomies.

“We are excited to share our robust hip portfolio, anchored by our new triple-taper femoral stem, Z1, and our well-established G7 Acetabular System,” said Ivan Tornos, President and Chief Executive Officer of Zimmer Biomet. “Through a series of strategic acquisitions and in-house innovations, we’ve curated a diversified portfolio of hip implant solutions and innovative enabling technologies that provide surgeons with a wide array of options designed to address efficiency, accuracy, and customization with a goal to improve overall surgical outcomes for patients.”

“Building on the success of our G7 Acetabular System, we delivered the Z1 System to address demand for a versatile and adaptable triple-taper femoral stem that allows surgeons to customize care for a broad range of hip arthroplasty patients,” said Louis Galrao, President, Hips at Zimmer Biomet. “The Z1 and G7 systems are enhanced by our curated suite of enabling technologies, which are designed to complement a variety of surgical approaches and workflows to make AI-, robotic- and mixed reality-powered surgical navigation and guidance accessible and approachable for more surgeons and care teams.”

Dr. Jesse Otero of OrthoCarolina, and Dr. Jonathan Yerasimides of Louisville Hip & Knee Institute, performed the first patient cases using the Z1 System

At the AAHKS meeting, Zimmer Biomet will present positive data on the safety and durability of the G7 Acetabular System during the poster sessions.
