    Summary

    Degenerative spondylolisthesis is more common in older females and Black individuals, often affecting the L4-L5 vertebrae due to joint degeneration. Surgical intervention may relieve severe pain when conservative methods fail.

    Area of Science:

    • Orthopedics
    • Radiology
    • Epidemiology

    Background:

    • Degenerative spondylolisthesis (DS) is a common condition, particularly in older adults.
    • Understanding its demographic and anatomical prevalence is crucial for diagnosis and treatment.

    Purpose of the Study:

    • To investigate the epidemiological characteristics of degenerative spondylolisthesis.
    • To identify predisposing factors and the typical progression of vertebral slippage.

    Main Methods:

    • Analysis of twenty skeletons and two hundred patients diagnosed with degenerative spondylolisthesis.
    • Evaluation of demographic data, vertebral levels affected, and co-existing conditions.

    Main Results:

    • DS occurred four times more frequently in females and three times more in Black individuals compared to whites.
    • The L4-L5 interspace was most commonly affected, with a higher incidence in cases of sacralization of the fifth lumbar vertebra.
    • Slippage, resulting from articular process degeneration, did not exceed 30% and was not observed before the fifth decade or with spina bifida/isthmic spondylolisthesis.

    Conclusions:

    • A straight, stable lumbosacral joint predisposes individuals to DS by increasing stress on the L4-L5 intervertebral joint.
    • Conservative treatment is effective for most, but decompression laminectomy offers pain relief for severe, unrelieved symptoms.
