    Summary
    This summary is machine-generated.

    Long-distance running is linked to sesamoid bone disorders like chondromalacia and stress fractures. Many patients also exhibit anatomical variations in the foot

    Area of Science:

    • Orthopedics
    • Sports Medicine
    • Podiatry

    Background:

    • Sesamoid bones in the foot are crucial for biomechanics.
    • Disorders of the sesamoid bones can significantly impact foot function and athletic performance.
    • Previous research suggests a connection between overuse and sesamoid pathologies.

    Purpose of the Study:

    • To investigate the association between long-distance running and sesamoid bone disorders.
    • To identify common anatomical variations present in patients with sesamoid pathologies.
    • To enhance understanding of the etiology of sesamoid bone injuries in runners.

    Main Methods:

    • Retrospective review of 26 patients diagnosed with disorders of the foot's sesamoid bones.
    • Analysis of patient history, focusing on athletic activity, particularly long-distance running.

  • Radiographic assessment to identify anatomical variations at the metatarsophalangeal articulation.

    • Main Results:

    • A high association was found between long-distance running and sesamoid chondromalacia or stress fractures.
    • Thirty-eight percent of the reviewed patients presented with anatomical variations.
    • Identified variations included sesamoid size asymmetry, symmetrical enlargement, metatarsal condylar hypoplasia, and metatarsal rotational abnormalities.

    Conclusions:

    • Long-distance running is a significant risk factor for developing sesamoid bone disorders.
    • Anatomical variations may predispose individuals to sesamoid pathologies, especially in runners.
    • Further research into the biomechanical interplay between running, anatomy, and sesamoid health is warranted.
