    Summary

    A new weightbearing X-ray technique for the forefoot is described. This simple, reproducible method better reflects clinical situations and reveals a link between foot arch height and forefoot pain or calluses.

    Area of Science:

    • Orthopedics
    • Radiology
    • Podiatry

    Background:

    • Current radiological techniques for forefoot assessment can distort anatomical relationships.
    • Weightbearing conditions are crucial for accurately assessing foot biomechanics and clinical presentation.

    Purpose of the Study:

    • To introduce a novel axial weightbearing radiological technique for the forefoot.
    • To evaluate the technique's simplicity, reproducibility, and clinical relevance.
    • To explore correlations between forefoot structure, arch height, and symptomatic conditions.

    Main Methods:

    • A new axial weightbearing radiological technique was developed and applied to 50 subjects.
    • Subjects with neuromuscular or malalignment issues were excluded.
    • Forefeet were categorized based on pain, calluses, and arch definition.

    Main Results:

    • The described technique is simple, inexpensive, and reproducible, avoiding forefoot distortion.
    • Weightbearing imaging provides results closer to real-world clinical scenarios.
    • A correlation was found between a well-defined forefoot arch and pain-free, callous-free feet, versus a depressed arch in symptomatic feet.
    • Statistical significance was noted in the relative heights of the tibial and fibular sesamoids.

    Conclusions:

    • The new axial weightbearing technique offers a more accurate and clinically relevant assessment of the forefoot.
    • Forefoot pain and calluses are associated with a depressed arch, while healthy feet exhibit a well-defined arch.
    • The technique may aid in developing a new classification for hallux valgus.
