Outcome Measures

Primary Outcomes (1)

  • Overall Patient Success

    Overall success was a composite endpoint determined by the following clinical outcome measures: 1. Neck Disability Index ≥ 15-point improvement from baseline to 12 months post-operative, 2. No new clinically significant permanent abnormalities in neurological function (i.e. motor strength, nerve root tension signs, sensory and reflex signs) from baseline to 12 months post-operative, 3. No subsequent secondary surgical interventions (SSI) at the index level, and 4. No device-related serious events (dSAE) from intra-operative through 12-months post-operative. Please note that these time periods were intended to be from baseline to 24 months post-operative, but since the study was terminated early the 12 month time periods were utilized.

    12 months

Secondary Outcomes (15)

  • Change in Visual Analogue Scale (VAS) Neck Pain From Pre-treatment to 12 Months

    12 months

  • Change in Visual Analogue Scale (VAS) Left Arm Pain From Pre-treatment to 12 Months.

    12 Months

  • Change in Visual Analogue Scale (VAS) Right Arm Pain From Pre-treatment to 12 Months.

    12 Months

  • Change in Visual Analogue Scale (VAS) Right Shoulder Pain From Pre-treatment to 12 Months.

Eligibility Criteria

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

You may qualify if:

  • Male or female subjects, aged between 18 and 65 years inclusive.
  • Subjects who are able to give voluntary, written informed consent to participate in this clinical investigation and from whom consent has been obtained.
  • Subjects who, in the opinion of the Clinical Investigator, are able to understand this clinical investigation, co-operate with the investigational procedures and are willing to return to the hospital for all the required post-operative follow-ups.
  • Objective evidence of cervical disc disease in one vertebral level between C3-C7 defined as one or more of the following:
  • Shoulder and/or arm pain in a radicular distribution resulting from herniated disc or bony osteophytes (Consistent w diagnostic imaging including Axial CT, CT Myelogram, MRI and/or plain films)
  • Subjects with myeloradiculopathy resulting from mild spinal cord compression and nerve root impingement
  • Unresponsive to documented non-surgical management for ≥ 6 weeks and/or presents with progressive symptoms of nerve root or spinal cord compression in the face of continued non-surgical management (e.g., physical therapy, medication therapy, corticosteroid injections, etc.)
  • Minimum Neck Disability Index score of ≥30 % (15/50 points)

You may not qualify if:

  • Subjects who, in the opinion of the Clinical Investigator, have an existing condition that would compromise their participation and follow-up in this clinical investigation.
  • Subjects who are pregnant, lactating or wishes to become pregnant within the duration of the study.
  • Subjects who are known drug or alcohol abusers or with psychological disorders that could affect follow-up care or treatment outcomes.
  • Subjects who have participated in a clinical investigation with an investigational product in the last 30 days.
  • Subjects who are currently involved in any injury litigation claims.
  • Subjects with significant degeneration at more than one cervical level (e.g. DISH, ankylosing spondylitis, congenital abnormality, rheumatoid arthritis)
  • Subjects who have had any prior surgery at the level to be treated (subjects with a prior Laminotomy at the level to be treated may be included in the study)
  • Subjects who have marked cervical instability on lateral or flexion/extension x-rays defined as translation ≥3mm and/or ≥11 degrees of rotational difference to either adjacent level
  • Subjects who have presence of systemic infection or infection at the site of surgery
  • Subjects who have been diagnosed with malignancy
  • Subjects who have been diagnosed with a condition or require postoperative medication(s) that may interfere with bony/soft tissue healing
  • Subjects who have been diagnosed with Osteoporosis, Osteopenia, other metabolic bone disease or endocrine disorder known to affect osteogenesis.
  • Subjects with pre-existing neurological abnormalities other than deficits produced from the spinal lesion (e.g., MS, Parkinson's, CVA, diabetic neuropathy, peripheral neuropathy).
  • Subjects with morbid obesity defined as a BMI of ≥40, or more than 100 lbs (45.4kg) over ideal weight.
  • Subjects with any known allergy to titanium metal, polyethylene, metal alloy or carbon fibre reinforced polymer
  • +5 more criteria
