NCT07002918

Brief Summary

The goal of this observational study is to learn about the role of pre-operative paraspinal muscle atrophy in outcomes of lumbar spine fusion surgeries in patients with degenerative lumbar spine diseases. The main question it aims to answer is: Does paraspinal muscle atrophy worsen lumbar spine fusion surgeries outcomes? Participants undergoing lumbar spine fusion surgeries as part of their treatment for degenerative lumbar spine diseases will answer survey questions about their low back pain and daily activities for 1 year.

Outcome Measures

Primary Outcomes (1)

  • Oswerty disability index Arabic version (ODI)

    The Oswestry Disability Index (ODI) translates low back pain disability into a numerical score for better understanding and communication. It's a questionnaire used to assess the impact of low back pain on a person's daily life, work, and ability to perform specific tasks. The ODI translates into a score from 0-100, with higher scores indicating greater disability. This score helps clinicians and researchers quantify the functional disability caused by low back pain.

    Baseline, 2 weeks postoperative, 6 weeks postoperative, 3 months postoperative, 6 months postoperative and 1 year postoperative.

Secondary Outcomes (4)

  • Visual analogue scale (VAS)

    Baseline, 2 weeks postoperative, 6 weeks postoperative, 3 months postoperative, 6 months postoperative and 1 year postoperative.

  • Local kyphotic angle

    Baseline, 1 day postoperative, 6 months postoperative and 1 year postoperative.

  • Lumbar lordosis

    Baseline, 1 day postoperative, 6 months postoperative and 1 year postoperative.

  • EuroQol-5-dimension 5-level Arabic version (EQ-5D-5L)

    Baseline, 2 weeks postoperative, 6 weeks postoperative, 3 months postoperative, 6 months postoperative and 1 year postoperative.
