Primary Outcome Measures:
  • SF-36 version 1 [ Time Frame: 1-Year ]
    Health-realted quality of life outcome measure

  • Site and Physician Compliance [ Time Frame: 1 Year ]
    Goal = 80% compliance in enrolling 20 patients over 1 year with completed outcomes instruments

Secondary Outcome Measures:
  • Oswestry Disability Index (ODI) [ Time Frame: 1 Year ]
    Validated lumbar spine disease-specific outcomes instrument

  • Visual Analog Pain Score [ Time Frame: 1 Year ]
    Patient-reported pain intensity scored 1-10

  • Return to Work [ Time Frame: 1 Year ]
    Return to work assessments will be performed at 1,3,6, and 12 months post-operatively

  • 30 day complications [ Time Frame: 30 days ]
    death, myocardial infarction (MI), pulmonary embolism (PE), readmission, wound infection, new neurological deficit, re-operation

  • Delayed Surgical Complications [ Time Frame: 1 year ]
    re-operation, fusion complication, problems with hardware, deformity

Enrollment: 198
Study Start Date: September 2010
Study Completion Date: September 2012
Primary Completion Date: September 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Lumbar Microdiscectomy
Patients aged 18-80 with symptomatic lumbar disc herniation resulting in single nerve root compression recalcitrant to non-invasive therapies for at least 6 weeks
Procedure: Lumbar Discectomy
Microsurgical removal of disc that is compressing a nerve root
Experimental: Single-Level Lumbar Fusion
Patients aged 18-80 with symptomatic grade I degenerative or isthmic spondylolisthesis with mechanical back pain with or without radiculopathy recalcitrant to non-invasive therapies for at least 3 months
Procedure: Single-level lumbar fusion
pedicle screws with arthrodesis as directed by surgeon. Fusion can be posterolateral, interbody, or both.
