Digital replantation and amputation--comparison of function

J M Jones, R R Schenck, R B Chesney

    The Journal of Hand Surgery
    |March 1, 1982
    PubMed
    Summary

    Replanting thumbs and multiple digits significantly improves function. Replantation of a single finger offers limited functional benefit, suggesting careful consideration for such cases.

    Area of Science:

    • Orthopedic surgery
    • Hand surgery
    • Reconstructive surgery

    Background:

    • Determining optimal indications for digit replantation is crucial for patient outcomes.
    • Comparative functional analysis between amputated and replanted digits is needed.

    Purpose of the Study:

    • To compare the functional capabilities of patients with amputated digits versus replanted digits.
    • To establish clearer guidelines for digit replantation based on functional outcomes.

    Main Methods:

    • A comparative study design was employed.
    • Patient function was assessed using 10 daily activity tests.
    • Grip strength was measured and compared to the contralateral normal hand.

    Main Results:

    • Replanted thumbs and multiple digits demonstrated significantly greater grip strength.
    • Replanted single digits showed less pronounced functional improvement compared to multiple digits.
    • Functional analysis indicated limited necessity for single finger replantation.

    Conclusions:

    • Digit replantation, particularly for thumbs and multiple digits, is functionally beneficial.
    • Replantation of a single finger may not offer substantial functional gains.
    • The presence of opposing digits is key for prehension, influencing the value of multiple digital replantation.
