A minimally invasive anterior lumbar interbody fusion (ALIF) system uses autogenous bone grafts to stabilize patients with degenerative disc disease (DDD).

The Camber Spine (Wayne, PA, USA) ENZA-A Titanium ALIF system consists of a three-dimensional (3D) printed titanium body with multiple openings to allow a large volume of autogenous bone graft to be easily packed into the implant, and roughened cranial and caudal surfaces that encourage bone growth onto the surface of the device. The surfaces are deliberately designed with pores that average 500 microns in diameter, the optimal environment for bone growth that fully incorporates the implant with the vertebral bodies.

The ENZA-A features two sharpened anchor plates housed within the 3D-printed body until they are deployed into the adjacent vertebrae for fixation. Surgery time is reduced thanks to the single, inline instrumentation used to insert the device, deploy the anchor plates, and lock it in place. Patient safety is increased by minimizing the size of the incision and retraction required for implantation. The ENZA-A has been approved by the U.S. Food and Drug Administration (FDA) for use at one or two contiguous levels from L2 to S1 using supplementary fixation systems.

“With ergonomic instrumentation, this system is easy to use and makes implantation more streamlined,” said Seth Anderson, executive VP of new business development and surgeon relations at Camber Spine. “The ENZA-A is the second device in the ENZA-line of implants; this interbody, coupled with additional product launches expected later this year in the cervical and lateral markets, will continue to grow Camber Spine's presence as a market leader and innovator in minimally invasive spine surgery technology advancements.”

Interbody devices are designed to replace the intervertebral disc of the spine, enhancing stability in the region while the spine fuses. Over time, the packed bone graft material is gradually replaced by natural bone forming a solid piece. Fusion procedures typically use a posterior fixation device to the associated level, since the surgeons will implant interbody devices from an anterior approach and flip the patient over to implant a posterior pedicle screw device. This combination increases fusion success.
