First received: September 7, 2006
Last updated: May 7, 2008
Last verified: May 2008
In order to determine whether L4 and L5 primary dorsal rami and S1-3 lateral branch radiofrequency denervation is effective for sacroiliac (SI) joint pain, we are conducting a randomized, controlled study.

Condition Intervention
Low Back Pain Procedure: radiofrequency denervation

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Crossover Assignment
Masking: Single
Primary Purpose: Treatment

Further study details as provided by Johns Hopkins University:

Primary Outcome Measures:
  • visual analogue scale pain score, Oswestry Disability Index [ Time Frame: 1, 3 and 6 months postprocedure ]

Secondary Outcome Measures:
  • Medication reduction, global perceived effect, work status

Estimated Enrollment: 30
Study Start Date: November 2005
Study Completion Date: August 2007
Primary Completion Date: August 2007 (Final data collection date for primary outcome measure)
Detailed Description:
30 subjects with SI joint pain confirmed by SI joint injections will be randomized to receive either L4 and L5 primary dorsal rami and S1-3 lateral branch radiofrequency denervation or sham denervation. To facilitate patient blinding, in both groups 1 ml of lidocaine will be injected before true (or sham) denervation so patients cannot feel heating. The stimulation will be the same for both groups and blinding assessed after the procedure. Follow-up visits will be at 1,3 and 6-months postprocedure.
