Official Title: Freedom® Cervical Disc Use In The Treatment of Cervical Degenerative Disc Disease

Further study details as provided by AxioMed Spine Corporation:

Primary Outcome Measures:
  • Safety of FCD [ Time Frame: 6 months ] [ Designated as safety issue: Yes ]
    Monitor the safety (operative and post-operative adverse events through 6-months) of the FCD.

  • Performance of FCD [ Time Frame: 6 months ] [ Designated as safety issue: No ]
    Monitor the performance (radiographic evaluation of segmental non-fusion and device function) of the FCD through 6-months post-operative period.

Secondary Outcome Measures:
  • Incidence of AEs [ Time Frame: 2 year ] [ Designated as safety issue: Yes ]
    Examine the incidence of adverse events including device revision, removal or supplemental fixation through the 2-years post-operative period.

  • Neck/Arm Pain [ Time Frame: 2 years ] [ Designated as safety issue: No ]
    Examine changes in neck and arm pain throughout the 2-years post-operative period.

  • Neurological function [ Time Frame: 2 years ] [ Designated as safety issue: No ]
    Examine changes in subject neurological function throughout the 2-years post-operative period.

  • Subject Function [ Time Frame: 2 years ] [ Designated as safety issue: No ]
    Examine changes in subject function throughout the 2-years post-operative period.

  • Radiographic Measurements [ Time Frame: 2 years ] [ Designated as safety issue: No ]
    Examine changes in radiographic measurements of the target, adjacent and cervical segment levels from discharge through the 2-years.

  • Examine AEs [ Time Frame: 2 years ] [ Designated as safety issue: Yes ]
    Examine all adverse events throughout the 2-years post-operative period

Arms Assigned Interventions
Experimental: Freedom Cervical Disc Device: Freedom Cervical Disc


Ages Eligible for Study:   21 Years to 65 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Skeletally mature males or females, aged 21 to 65 years old, inclusive.
  • Single, or adjacent, 2-level degenerative disc disease at C3-C7, inclusive.
  • Subject is a surgical candidate for an anterior approach to the cervical spine.
  • Minimum of 6 weeks of unsuccessful conservative treatment.
  • Subject with at least moderate preoperative pain and functional impairment
  • Subject is mentally and physically able to comply with protocol, postoperative compliance instructions, and follow-up schedule through 2-years.
  • Subject must understand and sign the written Informed Consent form.

Exclusion Criteria:

  • Subject with axial neck pain only who does not demonstrate concurrent arm pain or progressive neurological deterioration (specifically numbness or muscle weakness in the arm).
  • An active infection at the operative site or active systemic infection at the time of surgery.
  • Known or suspected allergy to titanium, polyurethane, cobalt, chromium, molybdenum or silicone.
  • Previous spinal fusion at the involved, or adjacent, cervical level(s).
  • Congenital or acquired structural defect at the operative levels (s) or their immediately adjacent level(s).
  • Significant osteoporosis in the cervical spine.
  • The investigator should assess if the subject has any of the following conditions at the index or adjacent level(s) which excludes the subject from study participation:
  • Cervical facet degeneration of the involved C3-C7 levels.
  • Previous trauma to, or fusion in, the C3-C7 levels.
  • Cervical instability at the index level(s) on neutral lateral or flexion/extension x-rays.
  • Radiographic findings of a fused or total collapsed disc.
  • Significant global cervical kyphosis (≥15º on Cobb angle measurement) or significant reversal of lordosis.
  • Female of childbearing potential, pregnant, breast feeding, or interested in becoming pregnant in the next two years
