Study Arms (2)

XL TDR

EXPERIMENTAL

The XL TDR is indicated for reconstruction of the disc following discectomy in skeletally mature subjects with symptomatic degenerative disc disease (DDD) of the lumbar spine at one level from L1-L5. DDD is defined as discogenic back pain with degeneration of the disc confirmed by patient history radiographic studies.

Device: XL TDROther: Lumbar fusion surgery

Outcomes from lumbar fusion study

OTHER
Other: Lumbar fusion surgery

Interventions

XL TDRDEVICE

This will be a lateral approach discectomy and reconstruction with the insertion of the XL TDR device.

Also known as: Total disc replacement

Eligibility Criteria

Age18 Years - 70 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • years of age (inclusive and skeletally mature) at the time of surgery
  • Diagnosis of image-confirmed symptomatic DDD at one of the following levels: L1/L2, L2/L3, L3/L4, or L4/L5
  • DDD diagnosed using patient history and image-confirmation such as (but not limited to), MRI, CT, or CT Myelogram with one or more of the following factors: contained herniated nucleus pulposus, facet joint degeneration/changes, decreased disc height \>2mm, and/or scarring/thickening of ligamentum flavum, annulus fibrosis, or facet joint capsule
  • Preoperative ODI ≥ 30 points
  • Unresponsive to conservative treatment for ≥ 6 months

You may not qualify if:

  • Symptomatic multilevel lumbar degeneration
  • Chronic back or leg pain of unknown etiology
  • Non-contained or extruded herniated nucleus pulpous
  • Previous or other lumbar surgery at any level except prior discectomy, laminotomy, or nucleolysis at the same level
  • Involved vertebral endplates dimensionally smaller than 45mm in the medial-lateral and/or 20mm in the anterior/posterior directions
  • Idiopathic scoliosis
  • Defect in the pars interarticularis
  • Radiographic signs of significant instability at operative level
  • Lytic spondylolisthesis or degenerative spondylolisthesis \> than grade 1
  • Bony lumbar spinal stenosis
  • Radiographic confirmation of significant facet joint disease or degeneration
  • Another lumbar device implanted
  • Clinically compromised vertebral bodies at the affected level due to trauma
  • Presence of metastases or active spinal tumor malignancy
  • Osteopenia, osteoporosis, or metabolic bone disease
  • +15 more criteria
