This critical addition to our line of lumbar fixation products will provide another way for surgeons to evolve and innovate their care.

Balanced spinal solutions provider Amendia Inc. is pleased to announce the commercial launch of its innovative Spondylolisthesis reduction system:, the Syzygy™ Stabilization System. Configured to provide immobilization and stabilization of spinal segments as an adjunct to fusion, Syzygy is ideal for use in the treatment of specific acute and chronic instabilities or deformities of the thoracic, lumbar, or sacral spine; and conditions such as fracture, dislocation, scoliosis, kyphosis, spinal tumor, or failed previous fusion.

Made of implant-grade titanium alloy, the Syzygy system features cannulated and non-cannulated screws, with self-tapping “grip quick” threads for maximum cortical bone purchase. Extended threads allow increased adjustability and control in 5mm increments for accurate reduction of spondylolisthesis. With available medial and cranial couplers, Syzygy facilitates up to 35mm of reduction with ±10° of cranial-caudal adjustment.

Dr. Hewatt M. Sims, MD, fellowship-trained orthopedic spine surgeon at Orthopedic Spine Center and Tift Regional Medical Center in Tifton, GA, performed recent spine surgeries with Syzygy. “Syzygy is a unique spinal system, providing quick, precise, and consistent reduction of the spondylolisthesis deformity,” Dr. Sims said.

The Syzygy system’s advanced design features, such as extended threads on each MAC Pin enable precise corrections and dual scales enhance optimal sagittal alignment.

"In working hand in hand with the medical community and spinal device marketplace, we know how important it is to provide patients and surgeons with a pedicle screw-based solution that consistently and accurately realigns the spine,” said Lawrence Boyd, Amendia’s Executive Vice President of Research & Development. “With surgeons providing care for a large number of patients who engage in athletics and rigorous physical activity, combined with a growing aging population, this critical addition to our line of lumbar fixation products will provide another way for surgeons to evolve and innovate their care.”

The Syzygy Stabilization system is part of Amendia’s growing list of products for balanced solutions for lumbar fixation systems. To learn more about Syzygy, including features and benefits and 510(k) information, please visit us at
