Osteotomy for "delta-phalanx" deformity

R J Smith

    Clinical Orthopaedics and Related Research
    |March 1, 1977
    PubMed
    Summary

    A delta phalanx, a complex syndactyly, can be trapezoidal and occur without extra digits. Surgical correction involves osteotomy and skin grafting for finger deformities.

    Area of Science:

    • Orthopedic surgery
    • Pediatric orthopedics
    • Hand surgery

    Background:

    • Delta phalanx is a congenital anomaly affecting finger development.
    • It is a complex form of syndactyly, often presenting with unique anatomical variations.

    Observation:

    • The typical triangular shape of a delta phalanx is not always observed; it can be trapezoidal.
    • A delta phalanx can exist independently, without the presence of a supernumerary digit.

    Findings:

    • Surgical correction is achieved through open wedge osteotomy.
    • Excised bone fragments from the osteotomy are utilized as grafts.
    • Z-plasty of the skin on the ulnar side of the finger is employed for closure.

    Implications:

    • This surgical technique addresses the complex deformities associated with delta phalanx.
    • It offers a method for correcting the anomaly, potentially improving finger function and aesthetics.
    • Understanding the varied presentations of delta phalanx is crucial for effective surgical planning.
