NON-SCREW Based Expandable Technology
Surgeons and Patients Can Count On
Expanding Innovations, Inc. (EI)
Expanding Innovations™ is an emerging medical device leader in expandable implant technology for spine surgery. Committed to solving the most formidable clinical problems faced by today’s spine surgeons, EI recognized the need to develop a next-generation expandable interbody cage platform that would mitigate the incidence of post-op cage collapse and vertebral body subsidence. Rising to the challenge, EI developed a revolutionary, NON-SCREW-based expandable cage that surgeons and patients can count on.
X-PAC® Expandable Cages replace the traditional inner implant drive screw with a powerful, continuous lifting mechanism. This patented lifting mechanism provides exceptional tactile feedback to the surgeon throughout implant expansion and robust locking of the implant upon completion of expansion. With over 14,000 cages implanted, surgeon adoption and trust in X-PAC Expandable Cage technologies continues to grow across the United States. Expanding Innovations continues to innovate with significant technology advancements and planned expansion of its X-PAC Portfolio in 2026.
Our Mission
Expanding Innovations is an emerging leader in the expandable interbody cage sector of the spine industry, dedicated to facilitating better patient care by solving the most pressing clinical challenges faced by spine surgeons. Their innovative solution, X-PAC Expandable Cage Technology, was designed to address challenges associated with the aging spine. X-PAC offers a breakthrough solution that prioritizes patient bone quality while mitigating the risk of subsidence and early torque out. The heart of the X-PAC design is the relocation of the lifting screw from the cage to the inserter instrument enhancing lifting power and versatility, facilitating optimal expansion tailored to individual patient bone quality. X-PAC ’s design enhances tactile feedback and creates an open architecture for post packability.
