Overview

Brief Summary

A multicenter, prospective, historically controlled study to evaluate the safety and effectiveness of the Triadyme-C device in comparison to other approved TDRs in the treatment of symptomatic cervical disc disease (SCDD) in subjects who are symptomatic at only a single level from C3 to C7 that are unresponsive to conservative management.

Inclusion Criteria

  • Male or female subject, age ≥
  • Diagnosis of radiculopathy or myeloradiculopathy of the cervical spine, with pain, paresthesia or paralysis in a specific nerve root distribution C3 through C7, including at least one of the following:
  • Neck and/or arm pain (at least 30 mm on the 100 mm visual analogue scale \[VAS\] scale).
  • Decreased muscle strength of at least one level on the clinical evaluation 0 to 5 scale.
  • Abnormal sensation including hyperesthesia or hypoesthesia; and/or
  • Abnormal reflexes.
  • Symptomatic at a single level from C3 to C
  • Radiographically determined pathology at the level to be treated correlating to primary symptoms including at least one of the following:
  • Decreased disc height on radiography, computed tomography (CT), or magnetic resonance imaging (MRI) in comparison to a normal adjacent disc.
  • Degenerative spondylosis on CT or MRI.

Exclusion Criteria

  • Have an active systemic infection or infection at the operative site.
  • Have a history of or anticipated treatment for active systemic infection, including HIV or Hepatitis C.
  • Have more than one immobile vertebral level between C1 to C7 from any cause including but not limited to congenital abnormalities and osteoarthritic "spontaneous" fusions.
  • Have previous trauma to the C3 to C7 levels resulting in significant bony or disco-ligamentous cervical spine injury.
  • Prior attempted or completed cervical spine surgery at any cervical level, except (1) a minimally invasive decompression that did not de-stabilize the segment upon flexion/extension or (2) a successful single-level anterior cervical fusion at non-index level (greater than 6 months prior to scheduled surgical treatment).
  • Have axial neck pain in the absence of other symptoms of radiculopathy or myeloradiculopathy justifying the need for surgical intervention.
  • Have disc height less than 3 mm as measured from the center of the disc in a neutral position.
  • Evidence of symptomatic moderate to severe facet joint degeneration or disease where the investigator feels this is a major contributor to the subject's pain as diagnosed by injection and imaging.
  • Have osteoporosis or is an increased risk of osteoporosis/osteopenia defined as a T-score less than -1.5 (i.e., -1.6, -1.7, etc.).
  • The SCORE/MORES will be used to screen if a dual energy X-ray absorptiometry (DEXA) scan is required. If SCORE/MORES value ≥ 6, then a DEXA is required.
