The purpose of the study is to learn which of two commonly prescribed treatments (surgery and non-surgical therapy) works better for specific types of low back pain.\n\nIn this part of the study, people with lumbar intervertebral disc herniation (damage to the tissue between the bones of the lower spine, or backbone) will receive either discectomy (surgical removal of herniated disc material) or non-surgical treatment. This study does not cover the cost of treatment.", "DetailedDescription"=>"Low back pain is considered one of the most widely experienced health problems in the United States and the world. This condition is the second most frequent condition, after the common cold, for which people see a physician or lose days from work. Estimated costs to those who are severely disabled from low back pain range from $30-70 billion annually. Rates of spinal surgery in the U.S. have increased sharply over time, and researchers have documented 15-fold geographic variation in rates of these surgeries. In many cases, where one lives and who one sees for the problem appear to determine the rates of surgery. Despite these trends, there is little evidence proving the effectiveness of these therapies over non-surgical management.\n\nOverall, the SPORT study is a multicenter, randomized, controlled trial for the three most common diagnostic groups for which spine surgery is performed: lumbar intervertebral disc herniation (IDH), spinal stenosis (SpS) and spinal stenosis secondary to degenerative spondylolisthesis (DS). This arm of the trial will deal with patients from the first diagnostic group. The study will compare the most commonly used standard surgical treatments to the most commonly used standard non-surgical treatments. We will conduct the study at 12 sites throughout the United States.\n\nThe primary endpoint of the study will be changes in health-related quality of life as measured by the SF-36 health status questionnaire. Secondary endpoints will include patient satisfaction with treatment, utility for current health in order to estimate quality-adjusted life years (QALYS) as the measure for cost-effectiveness, resource use, and cost.\n\nWe will follow patients at 6 weeks and 3, 6, 12, and 24 months to determine their health status, function, satisfaction, and use of health care. In this arm of the trial, we anticipate enrolling and randomly allocating a total of 500 participants. We will track an additional observational cohort to assess health and resource outcomes (1000 participants). Enrollment in the Observational cohort has been completed as of February 2003.\n\nWe will integrate data from the trial and observational cohorts to formally estimate the cost-effectiveness of surgical versus non-surgical interventions for IDH, SpS, and DS. On the basis of the results of this trial we will, for the first time, have scientific evidence as to the relative effectiveness of surgical versus non-surgical treatment for these three most commonly diagnosed lumbar spine conditions."}, "EligibilityModule"=>{"Gender"=>"All", "MinimumAge"=>"18 years", "StdAgeList"=>{"StdAge"=>["Adult", "Older Adult"]}, "HealthyVolunteers"=>"No", "EligibilityCriteria"=>"Inclusion Criteria:\n\nDuration of symptoms: 6 or more weeks.\nTreatments tried: Non-steroidal anti-inflammatory medical therapy and physical therapy.\nSurgical screening: Persistent radicular pain provoked by moderate exercise, sitting, increased abdominal pressure, decreased mobility, list (scoliosis), straight leg raising.\nTests: MRI to confirm diagnosis and level(s).\n\nExclusion Criteria:\n\nPrevious lumbar spine surgery.\nNot 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.\nPossible pregnancy.\nActive 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.\nCurrent fracture, infection, and/or deformity (greater than 15 degrees of lumbar scoliosis, using Cobb measure technique) of the spine.\nAge less than 18 years.\nCauda Equina syndrome or progressive neurological deficit (usually requiring urgent surgery).\nUnavailability for follow-up (planning to move, no telephone, etc.) or inability to complete data surveys.\nSymptoms less than 6 weeks.\nPatient currently enrolled in any experimental \"spine related\" study."}, "IdentificationModule"=>{"NCTId"=>"NCT00000410", "Acronym"=>"SPORT", "BriefTitle"=>"Spine Patient Outcomes Research Trial (SPORT) - Intervertebral Disc Herniation", "Organization"=>{"OrgClass"=>"OTHER", "OrgFullName"=>"Dartmouth-Hitchcock Medical Center"}, "OfficialTitle"=>"Spine Patient Outcomes Research Trial (SPORT): A Multicenter Randomized Trial for Intervertebral Disc Herniation (IDH)", "OrgStudyIdInfo"=>{"OrgStudyId"=>"U01 AR45444 NIAMS-004C"}, "SecondaryIdInfoList"=>{"SecondaryIdInfo"=>[{"SecondaryId"=>"U01AR045444", "SecondaryIdLink"=>"https://reporter.nih.gov/quickSearch/U01AR045444", "SecondaryIdType"=>"U.S. NIH Grant/Contract"}]}}, "ArmsInterventionsModule"=>{"ArmGroupList"=>{"ArmGroup"=>[{"ArmGroupType"=>"Active Comparator", "ArmGroupLabel"=>"Surgery", "ArmGroupDescription"=>"Diskectomy", "ArmGroupInterventionList"=>{"ArmGroupInterventionName"=>["Procedure: Diskectomy", "Procedure: Non-surgical treatments"]}}, {"ArmGroupType"=>"Active Comparator", "ArmGroupLabel"=>"Non-surgical intervention", "ArmGroupDescription"=>"Non-surgical treatments", "ArmGroupInterventionList"=>{"ArmGroupInterventionName"=>["Procedure: Non-surgical treatments"]}}]}, "InterventionList"=>{"Intervention"=>[{"InterventionName"=>"Diskectomy", "InterventionType"=>"Procedure", "InterventionDescription"=>"The surgeon will leave the nerve root freely mobile and undamaged following the procedure.
