Outcome Measures

Primary Outcomes (1)

  • Improvement in patient pain and ability to function

    The self-administered Neck Disability Index patient questionnaire is used to assess patient pain and ability to function. A successful outcome will be declared if: Postoperative Score - Postoperative Score is ≥ 15.

    24 months

Study Arms (2)

Anterior Cervical Discectomy Fusion

ACTIVE COMPARATOR
Device: ATLANTIS™ Cervical Plate System and allograft

BRYAN Cervical Disc Prosthesis

EXPERIMENTAL

BRYAN Cervical Disc Prosthesis is a cervical intervertebral disc prosthesis designed to provide for motion like the normal cervical functional spinal unit.

Device: BRYAN Cervical Disc Prosthesis

Interventions

Control treatment is commercially available allograft (without bone matrix paste) used in conjunction with the Medtronic Safamor Danek ATLANTIS™ Cervical Plate System.

Also known as: cervical plate, plate, fusion, cervical fusion
Anterior Cervical Discectomy Fusion

The intent is to treat stable degenerative disc disease by implanting the BRYAN Cervical Disc Prosthesis to provide motion like the normal cervical functional spinal unit.

Also known as: disc, cervical disc, artificial disc, BRYAN
BRYAN Cervical Disc Prosthesis

Eligibility Criteria

Age21 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • The indication studied was degenerative disc disease (DDD) at a single level between C3 and C7 for any combination of disc herniation with radiculopathy, spondylotic radiculopathy, disc herniation with myelopathy, or spondylotic myelopathy.
  • At least 6 weeks unsuccessful conservative treatment, except in cases of myelopathy requiring immediate treatment (e.g., acute onset of clinically significant signs);
  • Requirement for surgical treatment demonstrated by CT, myelography and CT, and/or MRI;
  • Skeletally mature (≥ 21 years of age);
  • Preoperative Neck Disability Index score of ≥ 30 and at least one clinical sign associated with level to be treated;
  • Willing to sign informed consent and comply with protocol.

You may not qualify if:

  • Subjects were excluded if they had any of the following:
  • Any of the following at the treated level:
  • Significant cervical anatomical deformity; e.g., ankylosing spondylitis, rheumatoid arthritis, etc.
  • Moderate to advanced spondylosis. Patients who demonstrate advanced degenerative changes. Such advanced changes are characterized by any one or combination of the following: bridging osteophytes, marked reduction or absence of motion, collapse of the intervertebral disc space of greater than 50% of its normal height;
  • Radiographic signs of subluxation greater than 3.5 mm;
  • Angulation of the disc space more than 11 degrees greater than adjacent segments;
  • Significant kyphotic deformity or significant reversal of lordosis;
  • Axial neck pain as the solitary symptom;
  • Previous cervical spine surgery;
  • Metabolic bone disease, such as osteoporosis, defined as a BMD T-score equal to or worse than 2.5. If significant radiolucence is detected, a BMD scan in the spine, wrist, and femoral neck must be obtained.
  • Active systemic infection or infection at the operative site;
  • Known allergy or to titanium, polyurethane, or ethylene oxide residuals;
  • Concomitant conditions requiring steroid treatment;
  • Diabetes mellitus requiring daily insulin management;
  • Extreme obesity, as defined by NIH Clinical Guidelines Body Mass Index;
  • +5 more criteria
