Interbody Fusion Implant Fully Integrates with Vertebral Bodies

A new minimally invasive anterior lumbar interbody fusion (ALIF) device provides support and integrated fixation.

The Camber Spine Technologies (Wayne, PA, USA) ENZA-A Titanium ALIF system is an interbody fusion device indicated for use with autogenous bone graft in patients suffering from degenerative disc disease (DDD) at one or two contiguous levels from L2 to S1. The implants may be placed via a laparoscopic or an open anterior approach, and feature two anchor plates—housed within the three-dimensional (3D) printed titanium body—that are deployed into adjacent vertebrae to provide fixation. The use of supplementary fixation systems is also recommended.

ENZA-A Titanium ALIF has a roughened surface texture designed to encourage bone growth onto the cranial and caudal surfaces of the device. The upper and lower facets are deliberately designed with pores that average a large 500 microns in diameter, the optimal environment for bone ingrowth. In addition, the implant has multiple openings that allow large volumes of autogenous bone graft to be easily packed inside, further facilitating fusion. Proprietary inline instrumentation is used to insert the device, deploy the anchor plates, and lock it in place.

“ENZA-A leverages two of Camber Spine's highly innovative platform technologies,” said Daniel Pontecorvo, CEO of Camber Spine Technologies. “The vast interest and success of our first generation ENZA with Duo Presa anchor technology and our line of SPIRA products with Surface By Design inspired us to combine their defining attributes to create this next generation ENZA-A Titanium ALIF.”

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. Fusion procedures also 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.
