    Area of Science:

    • Hand surgery
    • Orthopedic surgery
    • Reconstructive surgery

    Background:

    • Traumatic amputation and congenital hypoplasia often result in digit loss.
    • Useless or malformed digits (middle or ring finger) may require surgical intervention.
    • Restoring hand function and aesthetics after digit loss is a significant clinical challenge.

    Purpose of the Study:

    • To describe the surgical technique and outcomes of ray transposition for hand reconstruction.
    • To evaluate the effectiveness of transposing the second or fifth ray in cases of central digit loss.
    • To improve the functional and aesthetic results following severe hand trauma or congenital anomalies.

    Main Methods:

    • Performed ray transposition (second or fifth ray) in fourteen cases.

    Related Experiment Videos

  • Utilized osteotomies at the metacarpal base for internal fixation of the transposed ray.
  • Adjusted the division level of the fifth ray to achieve a more normal digit length.

    • Main Results:

    • Successfully reconstructed digits in fourteen patients using ray transposition.
    • The technique addressed traumatic amputations and congenital hypoplasia of central digits.
    • Transposition of the fifth ray was modified to enhance the appearance of digit length.

    Conclusions:

    • Ray transposition is a viable surgical option for reconstructing central hand digits.
    • The described technique offers a method to restore both form and function after digit loss.
    • Metacarpal osteotomy and internal fixation provide stable reconstruction for transposed rays.
