Outcome Measures

Primary Outcomes (6)

  • Fat degeneration of muscles

    Fat degeneration of musculus erector spinae and multifidus muscles evaluated by comparing the pre-operative current MRI of the lumbosacral spine using the 2-point Dixon Technique and Goutallier classification in each group

    12 months after procedure

  • Fat degeneration of muscles

    Fat degeneration of musculus erector spinae and multifidus muscles evaluated by comparing the pre-operative current MRI of the lumbosacral spine using the 2-point Dixon Technique and Goutallier classification in each group

    24 months after procedure

  • Oswestry disability index (ODI)

    ODI is based on a questionnaire, which includes 10 items, each one has 6 possible answers. Each item is rated from 0 to 5 and the sum of all answers is evaluated on a scale from 0-100, with higher scores meaning more serious symptoms.

    12 months and 24 months after procedure

  • Oswestry disability index (ODI)

    ODI is based on a questionnaire, which includes 10 items, each one has 6 possible answers. Each item is rated from 0 to 5 and the sum of all answers is evaluated on a scale from 0-100, with higher scores meaning more serious symptoms.

    24 months after procedure

  • EQ-5D-5L

    EQ-5D is a standardized questionnaire tool developed by the EuroQol group as a measure of the quality of life linked to health, that can be used in a wide spectrum of health conditions and their treatment. The system has 5 dimensions: mobility, being able to take care of oneself, every-day activities, pain/discomfort and anxiety/depression. Each system can be graded from 1-5, where 1 means no problems in the area and 5 meaning extreme problems. T Changes in the visual analogue scale (VAS) of lower limb pain evaluated on a scale of 0 to 10
