FDA cleared the CORUS Posterior Cervical Stabilization System 3D-T on a 510(k). Providence Medical Technology announced it October 13 from San Antonio. The implant is indicated as an adjunct to posterior cervical fusion, to immobilize and stabilize spinal segments in patients with cervical degenerative disc disease.
The 3D-T is a printed porous titanium version of the original machined CORUS implant. Providence says the lattice carries about 1.5 times the surface area and eight times the surface roughness of the earlier part, and that it holds packed bone graft. Surgeons place it bilaterally through a posterior approach, and it ships as a sterile, single-use instrument set.
The company rests the platform on a Level 1 randomized trial of the original CORUS, NCT04229017, with interim results published in Spine in May 2025. That trial reported higher fusion rates at 12 and 24 months and a lower two-year revision rate when posterior instrumentation was added to multilevel anterior fusion. Clearing a printed geometry off a machined predicate normally turns on mechanical testing and a surface characterization package rather than new clinical data.
Providence showed the device for the first time at the NASS annual meeting in San Antonio, October 14 to 17.
