Optimizing Lumbar Fusion
Where It Matters Most

For patients where traditional hardware isn't enough.

CORUS-LX offers a facet-based approach to achieving 360° stability-especially for high-risk and revision patients.

Spans the Facet with points of fixation designed for increased stability & fusion
Dedicated Bone Preparation Instruments (inner and outer decorticator)
Tissue-sparing technique for joint access, decortication, and bone graft delivery
Implant with Self-Locking Screw serves as a reservoir for bone graft material

Facets Matter

Superior Surface & Density

Greater surface area for fusion when combined with interbody lumbar fusion
Higher bone density in the facet region vs vertebral body

Facet Region has Higher Bone Mineral Density vs Vertebral Body.¹

Anatomical Region	Mean BMD Total(mgCa²⁺HA/mL)	Percent Cortical Bone(% by Volume)
Inferior articular process	392.4 ± 98.4	51 ± 18.3
Pedicle	305.5 ± 77.0	36 ± 11.6
Superior articular process	306.8 ± 79.2	34 ± 13.9
Vertebral body	147.2 ± 26.9	10.9 ± 5.2

Abbreviations: BMD, bone mineral density; Ca²⁺HA, calcium hydroxyapatite

Sterile-packaged Navigation-ready For Perioperative Efficiency

CORUS-LX simplifies MIS procedures,
reduces tissue disruption, while offering:

Effortless facet joint access when paired with the CORUS™ Navigation Access System.
Sterile instrumentation designed to minimize cost for re-sterilization process.
Includes a portal system for mini-open procedures not larger than 16mm.

CORUS-LX offers a facet-based approach to achieving 360° stability-especially for high-risk and revision patients.

Powerful Facet Stabilization

Significant reductions in the range of motion across all measurements.
Comparable ROM reduction to traditional pedicle screw construct (PSR).(3)
A viable alternative for increasing spinal stability in LLIF procedures.

About Providence Medical Technology

Our Mission is to establish Circumferential Cervical Fusion (CCF) as the standard of care for high-risk patients.

Indications for Use, CORUS™-LX LevelOne

A. CORUS SPINAL SYSTEM-LX:

The CORUS Spinal System-LX is a set of instruments indicated to be used to perform posterior lumbar fusion in patients with lumbar degenerative disc disease.

B. CORUS-LX IMPLANT:

CORUS-LX Implant is posterior spinal instrumentation with integrated screw fixation intended to provide immobilization and stabilization of spinal segments. CORUS-LX is placed bilaterally through a posterior surgical approach and spans the facet interspace with points of fixation at each end of the construct.

CORUS-LX is intended to provide temporary stabilization as an adjunct to a 1 or 2 level interbody lumbar fusion with autogenous and/or allogenic bone graft and must be accompanied with an FDA cleared intervertebral body fusion device implanted at the same spinal level(s), and may be used with a pedicle screw and rod system implanted at the same spinal level(s).

CORUS-LX is indicated for the treatment of patients with lumbar degenerative disc disease (DOD) from L4 to S1 in skeletally mature patients who have failed conservative care.
