  1. Hip osteoarthritis prevalence estimates by three radiographic scoring systems.

    Article - En anglais


    To estimate and compare the age-and sex-specific prevalence of radiographic hip osteoarthritis (RHOA) in a population-based study of the Pima Indians, using 3 atlas-based methods for assessing features of RHOA.


    Pelvic radiographs from 755 Pima Indians age =45 years enrolled in a population-based study were read using the Kellgren/Lawrence (K/L) grading scale (grade 0-4) and 2 validated individual-radiographic-features (IRF) scales (grades 0-3 for narrowing and osteophytes).


    The age-and sex-specific prevalence of RHOA among Pima Indians assessed using the K/L scale was<10% in all age and sex groups.

    The prevalence of grade =2 osteophytes assessed using the 2 IRF scales were similar to each other in all age and sex groups.

    However, differences between the 2 IRF scoring systems were found for the prevalence of grade =2 joint space narrowing.


    Pima Indians have an age-and sex-specific prevalence of RHOA similar to that found in the US population.

    Our finding of different joint space narrowing prevalence by the 2 IRF grading scales supports the use of the same atlas-based case definitions for determining disease prevalence for comparative studies.
