Hedron IA 3D printed ALIF spacer used in vertebral body fixation procedure


Globus Medical has announced the first procedure using the Hedron IA implant, a 3D printed integrated ALIF spacer that leverages anchors or screws for vertebral body fixation. The minimally invasive outpatient procedure was performed at Englewood Health (Englewood, New Jersey, USA) by Joshua S Rovner.

Hedron IA integrated lumbar spacers are integrated lumbar interbody fusion devices intended for use in patients with degenerative disc disease (DDD) at one or two contiguous levels of the lumbosacral spine (L2-S1).

“Offering my patients the benefits of smaller incisions and less exposure to potential complications is why I specialise in minimally invasive surgery,” said Rovner. “For the ALIF procedure, I require an implant that’s easy to insert yet provides a sturdy construct. Hedron delivered with the additional benefit of endplate-to-endplate porosity to promote fusion.”

Hedron spacers feature a biomimetic porous scaffold designed to promote bone formation onto and through the implant. Unlike first generation 3D printed implants, Globus Medical said in a press release announcing the procedure, Hedron strikes the optimal balance of strength and porosity through a sturdy frame and a pore size distribution similar to trabecular bone.

“The launch of Hedron demonstrates our commitment to improving patient outcomes by commercialising innovative musculoskeletal solutions that advance our market leading position,” said Mark Adams, VP of Product Development. “Hedron IA is the second in a full line of 3D printed interbody fusion spacers with an internal architecture that demonstrates significantly more bone ingrowth in an animal model at six weeks post-op compared to PEEK and titanium implants.”
