Neurovascular flaps to the hand.

B Strauch, B Greenstein

    Hand Clinics
    |May 1, 1985
    PubMed
    Summary

    Free flaps enable sensory restoration in injured upper extremities, offering a single-stage solution for complex reconstructions. While protective sensation is achievable, fine two-point discrimination is limited, setting a high standard for reconstructive surgery.

    Area of Science:

    • Reconstructive Surgery
    • Microsurgery
    • Sensory Restoration

    Background:

    • Restoring sensation in injured upper extremities is a key goal in reconstructive surgery.
    • Free flaps offer a viable option for reconstruction when sensory end organs are destroyed.
    • Composite tissue transfer provides a single-stage solution, unlike multi-stage tissue transfers.

    Purpose of the Study:

    • To evaluate the effectiveness of free flaps in achieving sensory recovery in the upper extremity.
    • To compare the outcomes of different free flap techniques for sensory reconstruction.
    • To assess the potential for achieving protective sensation and fine two-point discrimination.

    Main Methods:

    • Review of free flap techniques used for upper extremity reconstruction.
    • Analysis of sensory outcomes, including protective sensation and two-point discrimination.
    • Comparison of flap types and donor site morbidity.

    Main Results:

    • Free flaps facilitate one-stage reconstructions by providing direct blood supply to scarred areas.
    • Protective sensibility has been reported with various flaps, but fine two-point discrimination is mainly documented with the first web space flap.
    • Donor site morbidity and skin-matching issues persist with larger flaps.

    Conclusions:

    • Free flaps are valuable for sensory reconstruction in the upper extremity, enabling single-stage procedures.
    • Achieving near-normal sensibility, particularly fine two-point discrimination, remains a challenge and a benchmark for flap evaluation.
    • Further research is needed to optimize flap selection and techniques for superior sensory outcomes.
