Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
This single centered study will enroll up to 70 subjects (n = 35 per group), with subjects followed for 24 months post-surgery. All subjects enrolled in the study will be recruited from a pool of subjects eligible for combined interbody/posterolateral lumbar fusion surgery.
Subjects will be randomized in the trial to receive either the Nexxt Spine Nexxt MatrixxTM 3D-printed titanium cage or the HonourTM PEEK cage supplemented with a pedicle screw system and milled local autograft bone. Subject randomization will be stratified according to smoking status. Subjects will be blinded to their group status for the duration of the study assessments and procedures (24 months post-operatively). Subject study data will be collected preoperatively, intra-operatively and postoperatively at 3, 6, 12, and 24 months.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
3D-printed titanium cage
Subjects enrolled in this arm will have the Nexxt Spine Nexxt MatrixxTM 3D-printed titanium cage (interbody cage) implanted at each level of 1 or 2-level lumbar arthrodesis procedures. All constructs will be supplemented with a pedicle screw system (Depuy Synthes Expedium) cleared for lumbar spinal fusion.
Interbody cage (titanium)
Subject will be implanted with a 3D-printed titanium cage during their lumbar interbody fusion surgery.
Poly-ether-ether-ketone (PEEK) cage
Subjects enrolled in this arm will have the HonourTM poly-ether-ether-ketone (PEEK) cage (interbody cage) implanted at each level of 1 or 2-level lumbar arthrodesis procedures. All constructs will be supplemented with a pedicle screw system (Depuy Synthes Expedium) cleared for lumbar spinal fusion.
Interbody cage (PEEK)
Subject will be implanted with a poly-ether-ether-ketone (PEEK) cage during their lumbar interbody fusion surgery.

Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
* Subject must be over the age of 18 years old.
* Subject has been unresponsive to conservative care for a minimum of 6 months.
* The subject must in the investigator's opinion, be psychosocially, mentally, and physically able to fully comply with this protocol including the required follow-up visits, the filling out of required forms, and have the ability to understand and give written informed consent.
Exclusion Criteria
* Subjects requiring additional bone grafting materials other than local autograft bone.
* Subject has inadequate tissue coverage over the operative site.
* Subject has an open wound local to the operative area, or rapid joint disease, bone absorption, or osteoporosis.
* Subject has a condition requiring medications that may interfere with bone or soft tissue healing (i.e., oral or parenteral glucocorticoids, immunosuppressives, methotrexate, etc.).
* Subject has an active local or systemic infection.
* Subject has a metal sensitivity/foreign body sensitivity.
* Subject is morbidly obese, defined as a body mass index (BMI) greater than 40.
* Subject has any medical condition or extenuating circumstance that, in the opinion of the investigator, would preclude participation in the study.
* Subject is currently involved in another investigational drug or device study that could confound study data.
* Subject has a history (present or past) of substance abuse (recreational drugs, prescription drugs or alcohol) that in the investigator's opinion may interfere with protocol assessments and/or with the subject's ability to complete the protocol required follow-up.
* Subjects who are pregnant or plan to become pregnant in the next 12 months or who are lactating.
* Subject is involved in or planning to engage in litigation or receiving Worker's Compensation related to neck or back pain.
* Subject is a prisoner.
