    Area of Science:

    • Anatomy
    • Orthopedics
    • Surgical Anatomy

    Background:

    • Anatomical variations of the hand can affect clinical presentations.
    • Understanding rare muscle origins is crucial for accurate diagnosis.

    Observation:

    • A patient presented with a tender dorsal hand mass.
    • The mass was identified as a rare extensor indicis brevis variant.

    Findings:

    • The extensor indicis brevis originated from the scaphoid ligament.
    • This variant represents a "short" index extensor muscle.

    Implications:

    • Knowledge of this variant is vital for diagnosing dorsal hand masses.
    • Awareness aids in planning tendon transfer surgeries.
  • Important for orthopedic surgeons and anatomists.
