Conservative Versus Aggressive Discectomy for Primary Disc Herniation With Radiculopathy - Full Text View

Purpose

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.

Estimated Study Completion Date:	December 2015
Estimated Primary Completion Date:	December 2012 (Final data collection date for primary outcome measure)

Arms	Assigned Interventions
Experimental: CS conservative discectomy	Procedure: conservative discectomy a smaller incision with removal of the disc fragment with little invasion of the disc
Active Comparator: AS	Procedure: aggressive discectomy a large open incision with aggressive removal of the disc fragments and curettage of the disc space

Detailed Description:

objectives:to compare the effect of two type surgery(conservative discectomy and aggressive discectomy)on disc herniation with radiculopathy after long-term follow-up.

methods:the patients who were confirmed suffer from disc herniation with radiculopathy and failed to nonsurgical treatment will be divided into two groups, and will be follow up 3~6 years for seeking the effect on disc space preservation and recurrent.

outcome measures:the rate of pain release and patients satisfaction were measured by SF-36,ODI,VAS,score post-OP. the height of disc was measured on X-ray film by the end point.

Eligibility


Ages Eligible for Study:	18 Years to 40 Years
Genders Eligible for Study:	Both
Accepts Healthy Volunteers:	No

Criteria

Inclusion Criteria:

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).

Exclusion Criteria:

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.
