ENABLING TOTAL SEGMENTAL FUSION. ENGINEERED FOR OSSEOINTEGRATION.

New porous titanium architecture.

The Next Dimension in Posterior Fixation

CORUS™ PCSS 3D–T features a pore structure consistent with those shown in published literature to promote vascularization and osseointegration.¹⁻⁴

SIMILAR TO CANCELLOUS BONE ⁵˒⁶˒⁷

Interconnected lattice provides a scaffold for bony ingrowth

Overall porosity 73–75%
Pore size range ~400–800 μm
Average pore size 609 μm

INCREASED SURFACE AREA AND ROUGHNESS

1.5X greater surface area vs machined PCSS⁸
8X surface roughness vs machined PCSS⁹

Supports Multilevel Fusion

Circumferential cervical fusion is associated with greater biomechanical stability and higher fusion rates in multilevel cervical fusion. Tissue-sparing posterior techniques allow surgeons to add supplemental posterior fixation and fusion without increasing hospital length of stay.¹⁰

Proprietary Porous Lattice

Designed for isotropic load distribution (absorbing force equally from all directions) while providing open pathways for vascularization and bony ingrowth.

Enhanced Anatomical Fit

Optimized geometry to address variable patient anatomy.

Designed for Perioperative Efficiency

Sterile-packaged & single-use
Numbered instruments
Tissue-sparing technique*

* CORUS PCSS 3D-T supports tissue-sparing portal-based, mini-open, fluoroscopic, and navigated techniques as well as open procedures based on surgeon preference and patient anatomy.

As with all medical devices, there are risks and considerations to device use. Please refer to the device labeling for a full discussion of potential risks, contraindications, warnings, precautions, and instructions for use. Rx only.

Treatment may not be appropriate for all patients and all patients may not benefit. Results vary.

Indications for Use

Indications for Use, CORUS™ PCSS 3D-T

CORUS™ Posterior Cervical Stabilization System 3D-T (CORUS PCSS 3D-T) is posterior spinal instrumentation with integrated screw fixation intended to provide immobilization and stabilization of spinal segments. CORUS PCSS 3D-T is placed through a posterior surgical approach in up to 3 consecutive levels of the cervical spine (C3–C7) and achieves bilateral facet fixation by spanning the facet interspace at each level with points of fixation at each end of the construct.

CORUS PCSS 3D-T is intended as an adjunct to posterior cervical fusion (PCF) and is only intended to be used in combination with an FDA cleared/approved spine stabilization hardware for anterior cervical fusion at the same level(s).

CORUS PCSS 3D-T is indicated for skeletally mature patients with degenerative disc disease (DDD). DDD is defined as radiculopathy and/or myelopathy, neck and/or arm pain of discogenic origin as confirmed by radiographic studies. CORUS PCSS 3D is to be used with autogenous bone and/or allogenic bone graft.

Indications for Use, CORUS™ Spinal System

CORUS™ Spinal System is a set of instruments indicated to be used to perform posterior cervical fusion in patients with cervical degenerative disc disease.
