Detailed Description

A multi-center (up to 20 investigational sites), prospective, non-blinded investigation of the MOTUS Total Joint Replacement (TJR) device. These data will be compared to a lumbar interbody fusion (tra...

Eligibility Criteria

Inclusion

  • Male or female, age 21-80 (inclusive) with at least 3 years of life expectancy
  • The subject has a primary diagnosis of symptomatic lumbar degeneration with or without foraminal or recess stenosis of the lumbar spine at a single level from L1/L2 to L5/S1 confirmed by subject history and radiographic imaging (CT, MRI, X- rays) with no more than a Grade 1 (\<25% translation) spondylolisthesis. Symptomatic lumbar degeneration that may be associated with a co-morbid condition such as:
  • Herniated nucleus pulposus
  • Scarring/thickening of the ligamentum flavum, annulus fibrosus, or facet joint capsule
  • Facet joint degeneration/osteophyte formation
  • Spondylosis (defined by the presence of osteophytes)
  • Disc degeneration and/or annular degeneration; and/or
  • Lumbar stenosis defined by spinal cord or nerve root compression
  • Exhausted conservative treatment (e.g. bed rest, physical therapy, medications, TENS (transcutaneous electrical nerve stimulation), manipulation, and/or spinal injections) for at least 3 months or has a neurologic emergency
  • Preoperative Oswestry Disability Index score ≥ 40/100 at baseline
  • Psychosocially, mentally, and physically able and willing to fully comply with this protocol including adhering to follow-up schedule and requirements and filling out forms
  • Signed informed consent.

Exclusion

  • More than one vertebral level requiring treatment
  • Previous instrumented surgery (i.e.: anterior disc replacement, spinal fusion, interspinous device, etc.) at the index lumbar level or an adjacent level
  • Degenerative or lytic spondylolisthesis greater than Grade 1 (25% translation)
  • Rotatory scoliosis at the index level
  • Congenital bony and/or spinal cord abnormalities at the index level
  • Subcaudal defect, disrupting the integrity of the pedicle
  • Clinically compromised vertebral bodies at the index level due to current or past trauma, e.g., by the radiographic appearance of the fracture callus, malunion or nonunion
  • Disrupted anterior longitudinal ligament at the index level
  • Overlying thoracolumbar kyphosis (greater than or equal to 15 degrees) within one level (includes target and adjacent level) of the level to be treated
  • Back pain of unknown etiology without leg pain
  • Severe spondylosis at the level to be treated as characterized by any of the following:
  • Autofusion (solid arthrodesis) determined radiographically (CT)
  • Totally collapsed disc, or
  • Vertebral body that cannot be mobilized
  • Known allergy to cobalt, chromium, molybdenum, nickel, polyethylene, titanium, or vitamin E
  • Unable to undergo an MRI scan, CT scan or other radiograph assessments
  • Osteopenia: The SCORE/MORES will be utilized for all females age \<50 and males age \<55 to screen if a DEXA scan is indicated. If SCORE/MORES value ≥ 6, then a DEXA scan is required. A DEXA scan is indicated for all females age ≥50 and all males age ≥55. If DEXA is required, exclusion will be defined as a DEXA bone density measured T score ≤ -1. An existing DEXA is allowed if completed within 6 months of subject screening;
  • Has history of any endocrine or metabolic disorder known to affect osteogenesis (e.g.: Paget's disease, renal osteodystrophy, Ehler-Danlos syndrome, or osteogenesis imperfecta)
  • Insulin-dependent diabetes mellitus
  • Lactating, pregnant or interested in becoming pregnant in the next 3 years
  • Active infection - systemic or local
  • Any medical condition requiring treatment with any drug known to potentially interfere with bone/soft tissue healing or receiving radiation therapy that is expected to continue for the duration of the study
  • Body Mass Index \> 40
  • Recurrent history of deep vein thrombosis, symptoms of arterial insufficiency, or thromboembolic disease
  • Systemic disease including Lupus disease, Reiter's disease, Rheumatoid disease, AIDS, HIV, hepatitis or autoimmune disease that requires immunosuppressive therapy, including biologics, for systemic inflammation
  • Spinal tumor
  • Active malignancy: A patient with a history of any invasive malignancy (except non-melanoma skin cancer), unless he/she has been treated with curative intent and there have been no clinical signs or symptoms of the malignancy for at least 5 years
  • Any degenerative muscular or neurological condition that would interfere with evaluation of outcomes, including but not limited to Parkinson's disease, amyotrophic lateral sclerosis (ALS), or multiple sclerosis
  • Has chronic or acute renal and/or hepatic impairment and/or failure or prior history of renal and/or hepatic parenchymal disease
  • Has a Waddell Signs of Inorganic Behavior score of 3 or greater
  • In the opinion of the investigator, the subject has a behavioral, cognitive, social or medical problem that may interfere with the assessment of the safety or effectiveness of the device
  • Current or recent history of chemical/alcohol abuse or dependency using standard medical definition of DSM-5 (Diagnostic and Statistical Manual) code
  • Currently smoking or using tobacco products, including e-cigarette products (e.g., vaping) (Use within 30 days of surgery date is considered 'current')
  • Currently pursuing or in active spinal litigation for medical negligence, or trauma, or workers compensation
  • Is a prisoner, incarcerated, or has been coerced to participate in the study that could impact the validity of results
  • Is currently participating in an investigational therapy (device and/or pharmaceutical) within 30 days prior to entering the study or such treatment is planned during the 24 months following enrollment into the study.
