NCT01204008

Brief Summary

Summary: This is a prospective randomize study to compare conservative and aggressive discectomy for treatment of disc herniation with radiculopathy. Study hypothesis: The investigators believe that conservative discectomy could preserve a higher disc space and has a better long-term outcomes.

Eligibility Criteria

Age18 Years - 40 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64)

You may qualify if:

  • Duration of symptoms: 6 or more weeks.
  • Treatments tried: Non-steroidal anti-inflammatory medical therapy and physical therapy.
  • Surgical screening: Persistent radicular pain provoked by moderate exercise, sitting, increased abdominal pressure, decreased mobility, list (scoliosis), straight leg raising.
  • Tests: MRI to confirm diagnosis and level(s).

You may not qualify if:

  • Previous lumbar spine surgery.
  • Not a surgical candidate for any of these reasons: Overall health which makes spinal surgery too life-threatening to be an appropriate alternative, dramatic improvement with conservative care, or inability (for any reason) to undergo surgery within 6 months.
  • Possible pregnancy.
  • Active malignancy: A patient with a history of any invasive malignancy (except non-melanoma skin cancer) is ineligible unless he or she has been treated with a curative intent AND there has been no clinical signs or symptoms of the malignancy for at least 5 years.
  • Current fracture, infection, and/or deformity (greater than 15 degrees of lumbar scoliosis, using Cobb measure technique) of the spine.
  • Age less than 18 years.
  • Cauda Equina syndrome or progressive neurological deficit (usually requiring urgent surgery).
  • Unavailability for follow-up (planning to move, no telephone, etc.) or inability to complete data surveys.
  • Symptoms less than 6 weeks.
  • Patient currently enrolled in any experimental "spine related" study.
