  • Patient who had two diagnostic medial branch blocks with significant (>50%) improvement on both injections.

Exclusion criteria

  • No patient related outcome measures available in hospital's patient charts

Treatment and study plan

Radiofrequency denervation of the cervical facet joint

Procedure

Radiofrequency denervation of the medial branch of the dorsal ramus of the cervical facet joint with a three-tined expandable needle.

Primary outcomes

  1. Pain measurement by numeric rating score

    Time frame: 2 months after injection in comparison to baseline

    The primary outcome of this study is pain measured with the numeric rating score (NRS): 11-point NRS ranging from 0 (no pain at all) to 10 (the worst imaginable pain). A score of zero (0) will indicate that the patient is pain free, while a score of ten (10) will indicate that they are experiencing the worst pain imaginable.

Secondary outcomes

  1. Patient Global Impression of Change (PGIC)

    Time frame: 2 months after injection

    The PGIC rating is increasingly being used for determining clinically important change in measures such as ratings of pain. This scale is designed to quantify patient's improvement or deterioration over time, usually either to determine the effect of an intervention or to chart the clinical course of a condition. The scales ask that a person assess his or her current pain, recall that status at a previous time-point, and then calculate the difference between the two.

    • very much improved
    • much improved
    • minimally improved
    • no change
    • minimally worse
    • much worse
    • very much worse

  2. Use of analgesics

    Time frame: 2 months after injection

    The quantity of analgesics that the patient assumes for the pain:

    • All stopped
    • Decreased
    • Equal
    • Increased

  3. Sleep

    Time frame: 2 months after injection

    Question: 'your sleep quality is:

    • Improved
    • Equal
    • Worsened'

  4. Walking ability

    Time frame: 2 months after injection

    Question: 'after the treatment, you can walk:

    • More than before
    • Same as before
    • Less than before'

  5. Patient satisfaction

    Time frame: 2 months after injection

    Question: are you satisfied with the result: YES/NO
