Brief Summary

In the past decade, spine surgery rates have dramatically increased in parallel to those of other procedural interventions. Persistent pain is a common occurrence after spine surgery, with the most commonly quoted prevalence rates ranging from 10% to 40%. This pain can be classified into failure to alleviate baseline pain, pain resulting from complications (e.g., arachnoiditis and epidural adhesions), and pain that ensues several years later as a sequele to alterations in spinal architecture and biomechanics (e.g., adjacent segment discogenic or facetogenic pain) which is called failed back surgery syndrome ( FBSS )

Outcome Measures

Primary Outcomes (1)

  • numerical rating scale

    The VAS score was used that has 0-10 points. The 0 point represents the painless state and a score from 1 to 3 points represents mild pain, from 4 to 6 points represents moderate pain and from 7 to 10 points represents severe pain.

    12 months

Secondary Outcomes (2)

  • Oswestry Disability Index (ODI)

    12 month

  • pregabalin consumption

    12 month

Eligibility Criteria

Age18 Years+

Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Patients with history of lumbar surgery of at least 6 months duration in the past.
  • Patients over the 18 years of age.
  • History of persistent function-limiting lower extremity pain aggravated by "dural tug" (observed when the patient, sitting on the exam table with legs stretched out, bends forward, bringing on the back pain) with or without low back pain of at least 6 months duration after failure of conventional conservative management in most patients including NSAIDS, muscle relaxants (tizanidine, magnesium sulphate) and pregabalin.
