Brief Summary
The goal of this clinical trial is to assess the safety and effectiveness of the study device, CORUS-LX, as an adjunct to lumbar interbody fusion, when used in combination with pedicle screw and rod c...
Detailed Description
The study device is designed to provide surgeons a tissue-sparing solution for both preparing a fusion bed around the facet space in addition to stabilizing the joint in sync with percutaneous pedicle...
Eligibility Criteria
Inclusion
- Age 18-80 years (Skeletally Mature)
- Indicated for lumbar interbody fusion for treatment of degenerative lumbosacral disease at two contiguous disc levels between L4-S1 as determined by the following:
- a) Diagnosis of radiculopathy of the lumbar spine, with pain, including at least one of the following: i) Leg and/or buttock pain, weakness, numbness, or paresthesia ii) Low back pain iii) Neurogenic claudication b) Radiographically determined pathology (CT, MRI, X-rays) at the levels to be treated correlating to primary symptoms including at least one of the following: i) Decreased disc height in comparison to a normal adjacent disc. ii) Degenerative instability ≤ grade 1 spondylolisthesis (\<25% slip). iii) Recurrent disc herniation. iv) Central and/or foraminal stenosis.
- Oswestry Disability Index Score of \> 40/100 (Severe Disability).
- Unresponsive to non-operative, conservative treatment (rest, heat, electrotherapy, physical therapy, chiropractic care and/or analgesics) for:
- At least six weeks from symptom onset; or
- Have the presence of progressive symptoms or signs of nerve root/ spinal cord compression despite continued non-operative conservative treatment.
- Reported to be medically cleared for surgery.
- Physically and mentally able and willing to comply with the Protocol, including the ability to read and complete required forms
- Willing and able to adhere to the scheduled follow-up visits and requirements of the Protocol.
- Written informed consent provided by subject.
Exclusion
- Any disease or condition that, in the investigator's opinion, would preclude accurate radiographic evaluation of any treated vertebrae (e.g. morbid obesity).
- Any anatomy or condition that makes posterior fusion treatment infeasible (e.g. fused facets).
- Has, in the Investigator's opinion, any disease or condition that would preclude accurate clinical evaluation (e.g. neuromuscular disorders).
- Active systemic infection or infection at the operative site.
- Anticipated treatment for active systemic infection, including HIV or Hepatitis C.
- Previous trauma to any of the L3 to S1 levels resulting in significant bony or disco-ligamentous lumbar spine injury that may prevent device placements.
- Prior instrumented surgery or pseudoarthrosis at the operative or adjacent levels.
- Indicated for or history of laminectomy at any of the index or adjacent levels
- Fixed or permanent neurologic deficit related to the target treatment levels that cannot be improved with surgery
- Leg, buttocks, or back pain in the absence of other symptoms of radiculopathy or myeloradiculopathy justifying the need for surgical intervention.
- Symptomatic disc degeneration requiring surgical intervention at more or less than two levels.
- Diagnosis of spondylolisthesis, grade \>1.
- Diagnosis of lytic spondylolisthesis
- Diagnosis of iatrogenic, traumatic, or dysplastic spondylolisthesis
- Congenital bony and/or spinal cord abnormalities affecting spinal stability.
- Diagnosis of Paget's disease, osteomalacia or any other metabolic bone disease other than osteopenia.
- Diagnosis of osteoporosis, defined as a previous DEXA bone density T-score of ≤-2.5.
- Active malignancy or a history of any invasive malignancy (except non-melanoma skin cancer), unless treated with curative intent and without clinical signs or symptoms of the malignancy for at least five years.
- Has an uncontrolled seizure disorder.
- Cauda equina syndrome or neurogenic bowel/bladder dysfunction;
- Use of epidural steroids within 14 days prior to surgery.
- A concomitant condition requiring daily, high-dose oral steroids.
- High dose steroid use is defined as:
- Daily, chronic use of oral steroids of 5 mg/day or greater (steroid inhalers are not exclusionary).
- Use of short-term (less than 10 days) oral steroids at a daily dose greater than 40 mg within one month of the study procedure.
- Long-term use (\>6 months) of opioids \>120 mg morphine equivalents.
- Known allergy to titanium (Ti)
- A current or recent history (≤1 year prior to screening) of substance abuse that required medical treatment.
- Is pregnant, nursing, or interested in becoming pregnant within the next 3 years from the time of screening.
- Participation as a subject in any other clinical studies involving medical devices or drugs in the last 30 days prior to surgery
- A pending personal litigation relating to spinal injury (worker's compensation is not exclusionary).
- Anticipated or potential relocation greater than 50 miles that may interfere with completion of follow-up examinations.
- A mental illness or belongs to a vulnerable population, as determined by the investigator (e.g., prisoner or developmentally disabled), that would compromise ability to provide informed consent or compliance with follow-up requirements.
