The "antenna" procedure for the "hook-nail" deformity.

E Atasoy, A Godfrey, M Kalisman

    The Journal of Hand Surgery
    |January 1, 1983
    PubMed
    Summary

    The hook-nail deformity, common after fingertip amputations, can be corrected with surgery. This procedure removes the curved nail and reshapes the fingertip, restoring normal contour and function.

    Area of Science:

    • Hand surgery
    • Reconstructive surgery
    • Orthopedics

    Background:

    • Hook-nail deformity is a frequent complication following fingertip amputations.
    • This condition, often overlooked, can lead to significant functional impairment.

    Observation:

    • The deformity involves an abnormal curvature of the nail plate and altered fingertip contour.
    • Surgical intervention is necessary for correction.

    Findings:

    • The surgical technique involves removing the majority of the curved nail plate.
    • The pulp is carefully reflected and reshaped to achieve a normal contour.
    • The nail bed is elevated and straightened using small Kirschner pins.
    • A cross-finger flap is utilized to cover the resulting defect.

    Implications:

    • This surgical approach effectively corrects the hook-nail deformity.
    • Restoration of normal nail and fingertip anatomy improves function and aesthetics.
    • Addresses a disabling complication often neglected after fingertip injuries.
