Brief Summary:
This is a prospective, multi-center controlled observational clinical study. All subjects will receive Titan Endoskeleton TT/TO acid etched titanium implant for the planned procedure. Each site will have a predetermined bonegraft extender to be used in all enrolled subjects at that site.

Layout table for eligibility information
Ages Eligible for Study:   18 Years to 75 Years   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Sampling Method:   Probability Sample
Study Population
One hundred and fifty (150) subjects will participate in the study at a max of 15 clinical sites. All subjects will have been diagnosed with lumbar spine disease at one or two levels of the lumbar spine that requires lumbar interbody fusion procedure as per the opinion of the treating surgeon.Subjects will be offered the opportunity to participate in the trial if he/she is determined to be a candidate for TLIF fusion surgery. The population will be drawn from an existing patient population per participating site.

Inclusion Criteria:

  1. Be 18-75 years of age, and skeletally mature
  2. Have clinical and radiological evidence of degenerative disc disease at one or two levels of the lumbar spine between L2-S1. May also have spondylosis, spinal stenosis, or spondylolisthesis at these levels.
  3. In the opinion of the treating surgeon, must already be a qualified candidate for lumbar fusion surgery including 6 months of conservative care prior to surgical intervention.
  4. Psychosocially, mentally and physically able to comply with protocol, post-operative management and follow-up schedule.
  5. Subject must understand and sign the written Informed Consent.

Exclusion Criteria:

  1. Previous history of fusion surgery at the index level(s).
  2. Clinical, laboratory and/or radiological evidence of back pain secondary to acute or chronic infection, malignancy, other space occupying lesions and metabolic bone demineralization diseases (e.g. osteomalacia, gout, Paget's disease etc.)
  3. Osteoporosis defined as a DEXA bone density measurement T score ≤ 2.5 (Necessity for DEXA scan will be determined by investigator's standard of care)
  4. Any terminal or autoimmune disease including but not limited to HIV infection, rheumatoid arthritis or lupus.
  5. Any other concurrent medical disease that might impair normal healing process.
  6. Morbid obesity (BMI ≥ 40 kg/m2).
  7. Investigational drug or device use within 30 days.
  8. Currently a prisoner.
  9. Currently experiencing a major mental illness (psychosis, schizophrenia, major affective disorder) which may indicate that the symptoms are psychological rather than of physical origin.
