C7-T1 Epidural Steroid Injections Versus Targeted Injection for Treatment of Cervical Radicular Pain

Cervical radicular pain is a common, disabling problem, occurs in 83:100,000 individuals per year. Symptoms are most often caused by intervertebral disc herniation (21.9%) or central or foraminal stenosis from spondylosis (68.4%). Patients complain of pain in the head, neck, scapula or arm. The diagnosis of radicular pain is made clinically by history and physical examination, supported by imaging studies and electrodiagnostic tests. No study has compared the differences in pain, medication utilization, functional outcomes, or patient satisfaction between interlaminar and targeted epidural injections in the cervical spine. In theory, the technique of targeted epidural steroid delivery with a catheter has a lower risk of accidental vascular trespass or disc penetration during the procedure, and far less risk of dural penetration or spinal cord injury at rostral levels of the cervical spinal cord as compared with the interlaminar technique. The investigators hypothesize that this technique results in superior pain control, decreased medication use, improved function and fewer repeat injections. This data could improve patient safety and affect the evolving treatment guidelines for cervical epidural injections.

About this study

Cervical radicular pain is a common, painful, disabling problem, often treated by epidural steroid injection (ESI). Two techniques of steroid delivery into the cervical epidural space include the transforaminal and interlaminar approaches. We aimed to determine if the CIESI with versus without a catheter is associated with superior clinical outcomes at follow-up. We hypothesized that the use of a targeted epidural catheter technique would result in superior pain control, function, decreased analgesic use, and lower surgical incidence as compared to standard CIESI at C7-T1.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • All patients ages 18-75 with C2-6 unilateral radicular pain who are scheduled to undergo cervical epidural steroid injection treatment.
  • Pain lasting greater than 2 weeks.
  • Pain resistant to a trial of conservative therapy (i.e. oral steroids,nonsteroidal anti-inflammatory drugs, opioids, muscle relaxants, physical therapy or chiropractic care)

Exclusion criteria

  • Patient refusal.
  • Lack of consent.
  • Systemic infection or local infection over planned injection site in posterior cervical spine.
  • Bleeding disorder, current use of anticoagulants or anti-platelet medications.
  • Intrinsic spinal cord lesions in the cervical region.
  • History of central neurologic, cerebrovascular, demyelinating or muscular disease.
  • Concomitant use of oral or injected steroids.
  • Allergy to medications being used for injection procedures.
  • Inability to communicate with staff or to participate in follow up.
  • Pregnancy.
  • Inability to perform handgrip or arm strength testing.
  • Cognitive deficit or motor neuron disease.
  • Daily opiate use that preceded the onset of cervical radicular symptoms or daily opiate use exceeding 3 months prior to study inclusion

Treatment and study plan

Triamcinolone 80mg

Drug

C7-T1 Cervical interlaminar epidural steroid injection with Triamcinolone 80mg and 1 mL 1% lidocaine. Total volume is 2 cc.

Other names: Kenalog

Primary outcomes

  1. Percentage of Participants With ≥50% Pain Reduction on the Numeric Rating Score (NRS) for Pain

    Time frame: 1 month

    The percentage of participants who reported ≥50% pain reduction on the numeric rating score for pain at the 1 month follow-up assessment period.

    Numeric Rating Scale (NRS) for pain consists of a range where 0 (is no pain) and 10 (is extreme pain).

    Percentage of participants with pain reduction = 100% (number of participants with pain reduction/all participants)

Secondary outcomes

  1. Decrease of > 6.8 Point Reduction in Medication Quntification Scale (MQS-III)

    Time frame: 1 month

    The Medication Quantification Scale was designed as a method of quantifying different drug regimens (Harden et al, Journal of Pain, 2005). The detriment weights derived from the healthcare survey for each of the 22 medication classes are the critical values that when multiplied by a dosage score it gives a patient MQS score. It computes a single numeric value for a patient's pain medication profile. We recorded the names and doses of each medication being used then quantified the total burden of each subject's medication using the MQS-III. which assigns a measurement to each drug based on both the dose taken and its burdensomeness (derived from expert consensus).

  2. Patient Global Impression of Change Score (PGIC) Less Than 3

    Time frame: 1 month

    PGIC is a 7 point scale depicting a patient's rating of overall improvement. Patients rate their change as:

    1=Very Much Improved, 2=Much Improved, 3=Minimally Improved, 4=No Change, 5=Minimally Worse, 6=Much Worse, 7=Very Much Worse.

    A PGIC score less than 3 means the patient reported "much improved" to "very much improved."

  3. Greater Than or Equal to a 30% Reduction in Oswestry Neck Disability Index Score

    Time frame: 1 month

    This questionnaire has been designed to give us information to how neck pain has affected the ability to manage in everyday life. There are ten sections, 0 to 5 rating scale, in which zero means 'No pain' and 5 means 'Worst imaginable pain'. All the points can be summed to a total score. The maximum points scored is 50. The reported score divided by 50 is then transformed to a percentage score by multiplying by 100. The Minimum dectectable change (90 % confidence) is 5 points or 10 percent.
