    Summary
    This summary is machine-generated.

    Minimal changes in Perthes' disease, affecting 24 children, showed good outcomes regardless of treatment. Early recognition of distinct radiographic patterns is key to avoiding unnecessary interventions.

    Area of Science:

    • Pediatric Orthopedics
    • Pediatric Radiology

    Background:

    • Perthes' disease involves the femoral head in children.
    • Minimal changes can occur in Perthes' disease.
    • Classifications like Catterall's Group 1 exist.

    Purpose of the Study:

    • To analyze cases of Perthes' disease with minimal changes.
    • To identify distinct radiographic patterns within these cases.
    • To explore potential correlations with femoral head blood supply.

    Main Methods:

    • Retrospective review of 193 children with Perthes' disease.
    • Grouping cases based on the affected area of the femoral head.
    • Assessment of hip height using the epiphysial index and outcomes via Mose criteria.

    Main Results:

    • 24 of 193 children had minimal changes.
    • Cases were categorized by lesion location: anterior (10), posteromedial (7), lateral (3), central (4).
    • Most hips showed reduced height, but all achieved good Mose criteria outcomes irrespective of treatment.

    Conclusions:

    • Identified distinct radiographic patterns in minimal Perthes' disease cases.
    • These patterns appear to have a benign natural history.
    • Early identification of these patterns can prevent unnecessary treatments and may relate to femoral head blood supply.
