Femoral neck anteversion in perspective

J A Sullivan, J J Vanhoutte, B Remondino

    Clinical Orthopaedics and Related Research
    |March 1, 1982
    PubMed
    Summary

    Biplanar radiography for evaluating femoral anteversion is unreliable. Instead, focus on the femoral head-acetabulum relationship, which can be assessed with computed tomography, though its use in children should be limited due to radiation exposure.

    Area of Science:

    • Orthopedic surgery
    • Radiology
    • Pediatric orthopedics

    Background:

    • Routine evaluation of anteversion using biplanar radiography is common but lacks reliability and reproducibility.
    • Isolated measurement of femoral neck anteversion is considered outdated and clinically less relevant.

    Purpose of the Study:

    • To evaluate the clinical utility of biplanar radiography for assessing femoral anteversion.
    • To highlight the importance of the femoral head-acetabulum relationship over isolated anteversion measurements.
    • To discuss the role of computed tomography in evaluating hip joint morphology.

    Main Methods:

    • Review of current literature on anteversion measurement techniques.
    • Comparison of biplanar radiography and computed tomography (CT) for assessing femoral anteversion and hip joint relationships.
    • Discussion of radiation dose implications for pediatric patients undergoing CT scans.

    Main Results:

    • Biplanar radiography for anteversion measurement is deemed unreliable and poorly reproducible.
    • The relationship between the femoral head and acetabulum is clinically more significant than isolated femoral anteversion.
    • Computed tomography offers a comprehensive assessment of both anteversion and hip joint congruency.

    Conclusions:

    • Routine biplanar radiographic evaluation of anteversion is unnecessary and unreliable.
    • Assessing the femoral head-acetabulum relationship is crucial for hip joint evaluation.
    • Computed tomography is a valuable tool, but its use in children should be judicious due to radiation exposure.
