  • Device Related or Device Procedure Related Adverse Events

    Absence of major device related adverse events defined as radiographic failure, neurologic failure or failure by adverse event

    12 months

Secondary Outcomes (5)

  • Neck and Arm Pain Measurement

    pre-operative, 6 week, 3 month, 6 month, 12 month, 24 month

  • Patient Satisfaction

    6 week, 3 month, 6 month, 12 month, 24 month

  • Motor and Sensory Function in the Arm

Study Arms (2)

Prospective

All patients for whom the decision has been made to have the Synergy Disc system implanted and give informed consent will be enrolled in this study, following country-specific requirements.

Device: Synergy Cervical Disc system

Retrospective

Patients who have previously received the Synergy Disc system in the last ten years are eligible for inclusion in the retrospective data collection; a waiver of consent, or an informed consent, for the retrospective data collection from the medical records of the implanting surgeon will be sought per country-specific regulations.

Study Population

Patients should have had (retrospective cohort) or be scheduled to have the Synergy Disc cervical disc replacement. Patients will be followed per standard of care (SOC) for the physician as part of this study.

You may qualify if:

  • Age 21 or above at the time of the surgery. Have had (retrospective cohort) or the decision has been made to have (prospective cohort) the Synergy Disc implanted Skeletally mature patients for reconstruction of the disc from C3-C7 following a single or multiple level discectomy for intractable radiculopathy
  • Intractable radiculopathy and/or myelopathy with at least one of the following producing symptomatic nerve root and/or spinal cord compression:
  • herniated disc and/or osteophyte formation Symptomatic nerve root and/or spinal cord compression documented by patient history (arm or neck pain and/or neurologic deficit) and imaging (CT, MRI, x-rays, etc.) Failed a minimum of 6 weeks conservative treatment Written informed consent given by subject.

You may not qualify if:

  • Moderate to advanced spondylosis Diagnosis of osteoporosis Active systemic infection or infection at the operative site Pregnancy Marked cervical instability on lateral, coronal, or flexion/extension radiographs Cervical spine condition other than symptomatic cervical disc disease requiring surgical treatment at the involved level Severe pathology of the facet joints of the involved vertebral bodies Previous diagnosis of osteopenia or osteomalacia More than one immobile vertebral level between C1 and T1 from any cause Morbid obesity Vulnerable person (pregnant patients, emergency cases, children, prisoners and people without mental capacity)-
