Nexxt Spine has announced the first implantation of its NEXXT MATRIXX SA Cervical Turn-Lock system. The system is based around an intentionally engineered 3D laser printed titanium implant with varying pore sizes including 300μ, 500μ, and 700μ.
Each printed interbody offers architecturally significant geometry, including a 75% porous lattice to encourage osteointegration and radiographic visualisation. This is just one implant in the NEXXT MATRIXX line of products.
According to Nexxt Spine, this product was designed to eliminate the need for traditional plate and screw fixation, while providing a zero-profle constriction in anterior cervical fusion procedures. Furthermore, the company states that the 90 degree one step turn-lock for the mitigation of screw back out, and self-guided instrumentation are designed to increase surgeon confidence and procedural accuracy.
John Klekamp, Williamson Medical Center, Tennessee, USA, performed this initial implantation, he commented, “On behalf of my patient and myself we are both grateful and honored to have been the first recipient and surgeon to have benefited from Nexxt Spine’s latest technological advancement for the treatment of cervical spinal disorders. The release of NEXXT MATRIXX SA Cervical Turn-Lock System came at a most opportune time for us, as my patient had undergone a previous four level anterior cervical fusion from C3 to C7 four years ago. Over the course of time, he developed adjacent disc disease at the C7/T1 disc space, with severe bilateral neural foraminal stenosis and debilitating C8 radiculopathy. We faced the decision as to either perform an anterior plate removal and subsequent C7/T1 Anterior Discectomy and fusion and plate in a patient with challenging anatomy, or a posterior decompression with cervicothoracic instrumentation and fusion. The NEXXT MATRIXX SA.”
He continued, “Cervical Turn-Lock System allowed for C7/T1 anterior decompression and stabilization adjacent to the previous fusion without the need for plate removal and associated larger surgical exposure. The patient’s anatomy provided a challenging approach above the sternal notch, but once the discectomy was completed the implant placement provided additional distraction and indirect decompression of the bilateral neural foramen. The design of the interbody device incorporating the Matrixx lattice allowed for generous biologic material placement, and lattice for bony ingrowth. The specialized instruments for screw placement were critical for obtaining the necessary angles for screw hole preparation and placement into the C7 and T1 vertebral bodies. The locking mechanism was easily engaged, and secure.”
Since this initial implantation, over 50 surgeries have been performed using this device across the USA, according to Nexxt Spine’s press release. Klekamp noted, “My patient is now months from surgery and doing extremely well with complete resolution of his preoperative symptoms.”
