    Summary
    This summary is machine-generated.

    Early phases of this disease show articular cartilage overgrowth and bony infarction, leading to varied clinical presentations. Treatment focuses on maintaining femoral head mobility to prevent deformity, as infarction degree cannot be altered.

    Area of Science:

    • Orthopedics
    • Pediatric Orthopedics
    • Rheumatology

    Background:

    • Early and active phases of the disease are characterized by articular cartilage overgrowth.
    • Variable degrees of infarction occur within the bony epiphysis, contributing to clinical variability.

    Purpose of the Study:

    • To describe the key pathological changes in the early and active phases of the disease.
    • To elucidate the relationship between pathological changes and clinical presentation.
    • To outline the principles of treatment for managing growth disturbances and preventing deformities.

    Main Methods:

    • Pathological examination of affected joints.
    • Clinical observation and assessment of disease progression.
    • Evaluation of treatment outcomes focused on joint mobility and deformity prevention.

    Main Results:

    • Significant overgrowth of articular cartilage is a hallmark of the early disease phases.
    • The degree of bony infarction is variable and influences the clinical course.
    • Femoral head deformity is linked to adduction contracture, a preventable complication.

    Conclusions:

    • The observed pathological changes, particularly cartilage overgrowth and infarction, explain the variable clinical manifestations.
    • Treatment strategies should prioritize maintaining femoral head mobility to mitigate the risk of serious deformity.
    • Current treatments cannot reverse existing bony infarction but can manage secondary growth disturbances.
