[Equal pelvic crest or horizontal upper sacral line? (author's transl)]

P Edelmann

    Zeitschrift Fur Orthopadie Und Ihre Grenzgebiete
    |February 1, 1981
    PubMed
    Summary

    The primary goal in treating leg length differences is a horizontal sacrum. Pelvic crest height is an unreliable indicator; sacrum inclination and lumbar scoliosis relate to leg length discrepancies and pelvic asymmetry.

    Area of Science:

    • Orthopedics
    • Physiotherapy
    • Biomechanical analysis

    Context:

    • Leg length discrepancies are common musculoskeletal issues.
    • Pelvic asymmetry and lumbar spine curvature often accompany leg length differences.
    • Current diagnostic methods for pelvic alignment can be unreliable.

    Purpose:

    • To emphasize the importance of sacral horizontalization in managing leg length differences.
    • To clarify the relationship between leg length discrepancies, pelvic asymmetry, and lumbar scoliosis.
    • To differentiate between causal treatment of leg length differences and symptomatic management of sacral rotation.

    Summary:

    • The upper sacrum's horizontal position is the key treatment objective for leg length differences.
    • Pelvic crest height is an unreliable indicator of proper pelvic alignment.
    • Sacral inclination and lumbar spine side bending are influenced by leg length discrepancies and pelvic asymmetries.
    • Paradox lumbar scoliosis arises from sacral rotation and incongruent leg length differences.
    • Leg length differences allow for causal treatment, while sacral rotation requires symptomatic therapy.

    Impact:

    • Provides a clearer understanding of sacral positioning in relation to leg length differences.
    • Highlights the limitations of using pelvic crest height for assessing pelvic alignment.
    • Offers insights into the etiology of paradox lumbar scoliosis.
    • Guides clinicians towards appropriate treatment strategies for leg length discrepancies and associated spinal conditions.
