Objectives: The objectives of our work were to determine disability and study MRI findings of occupational-related lumbar disc degeneration and also to show the relationship between MRI grading of nerve root compromise with surgical grading.Participants and methods: The study included 103 workers with lumbar disc prolapse. Nerve roots were assessed on MRI and during surgery for the degree of compromise. Oswestry Disability Index and Visual Analogue Scale were used for assessment of disability and pain intensity pre- and post-operative respectively.Results: The majority of workers was less than 40 years and suffered from moderate to severe disability. 73.8% had grade IV disc degeneration mostly at the level of L4/L5. Nerve root compromise was found in 86.4% of workers. 48% of nerve roots were deviated and 32% were compressed, with significant correlation between MR grading of nerve root compromise and surgical grading (r = 0.89, P < 0.0001).Conclusion: Disability of occupational-related lumbar disc degeneration is a grave health problem between construction workers. MR imaging is a reliable tool for grading nerve root compromise in disc degeneration. Nerve root compromise is a significant factor to explain pain than the morphologic extension of disc material outside the intervertebral space
