Resumen

Introduction: Lumbociatic pain is a major cause of disability and absenteeism from work. Its pathophysiological substrate, mainly, is radiculopathy due to lumbar spondylosis or herniated discs. The objective of this study is to describe the alterations in the complementary tests (MRI and EMG), in patients with lumbociatalgia, with clinical suspicion of lumbosacral radiculopathy, in the context of herniated disc or spondylosis. Materials and methods: Retrospective study of 217 patients in which age and sex were analyzed; by MRI protrusions and herniated discs, discoosteophyte complexes, arthropathy, spondylolisthesis, canal stenosis, hypertrophy of the yellow ligament, sagittal vertebral alignment; neurogenic findings in muscles dependent on the spinal nerves from L3 to S1 have been analyzed by electrodiagnosis. Results: The mean age was 57.54 ± 12.31 years. The mean number of protrusions and herniated discs per spine was 1.26 ± 1.99. The number of patients with elements of spondylosis was: osteophytes n = 75, listhesis n = 40, canal stenosis n = 35, arthropathy n = 133, hypertrophy of the yellow ligament n = 72. Higher incidence of protrusions and herniated discs in L4-L5 (n = 144), of discoosteophytic complexes in L5-S1 (n = 42) and of neurogenic findings in the L5 spinal nerve (n = 169). The most characteristic vertebral alignment was preserved lordosis (n = 151). The elements of spondylosis increased with age significantly. Motor radiculopathies and discopathies increased with age in a non-significant way. Arthropathy, osteophytes, and L4 and L5 motor radiculopathies were more frequent in men. Conclusion: The poor anatomical correlation between the neurogenic findings in the muscles of a specific spinal nerve and the space-occupying lesions at the level of the homonymous intervertebral foramen, suggests that the rootlets of the cauda equina are damaged within the vertebral canal, due to occupying lesions of the cauda equina space, cranial to the expected intervertebral foramen.
