The below-the-knee amputation for vascular disease.

V Mooney, W Wagner, J Waddell

    The Journal of Bone and Joint Surgery. American Volume
    |April 11, 1976
    PubMed
    Summary

    This study found that a specific amputation technique using a long posterior flap for below-the-knee amputations in vascular disease patients leads to successful prosthesis use and better healing rates. The method did not negatively impact wound healing or functional outcomes.

    Area of Science:

    • Vascular Surgery
    • Prosthetics
    • Diabetic Foot Care

    Background:

    • Below-the-knee amputation is common for diabetic and arteriosclerotic vascular disease.
    • Optimizing prosthetic fitting and functional outcomes post-amputation is crucial.
    • Evaluating surgical techniques for improved healing and reduced revision rates is essential.

    Purpose of the Study:

    • To assess the efficacy of a specific below-the-knee amputation technique.
    • To evaluate the impact of rigid plaster dressing and delayed casting on wound healing and functional outcomes.
    • To compare the healing rate of the long posterior flap with other surgical techniques.

    Main Methods:

    • Retrospective analysis of 190 patients undergoing below-the-knee amputation.
    • Application of rigid plaster dressing followed by delayed plaster cast and pylon.

  • Assessment of surgical failure, revision rates, and time to prosthesis use.
  • Comparison of long posterior flap healing rates with previous data.

    • Main Results:

    • 167 out of 190 patients were successfully fitted with and utilized a prosthesis.
    • Surgical failure rate was 4.2%, with only eight patients requiring higher-level amputation.
    • The rigid plaster dressing technique did not impede wound healing or functional recovery.
    • The long posterior flap demonstrated a significant advantage in healing rate compared to other flaps.

    Conclusions:

    • The described amputation technique is effective for below-the-knee amputations in vascular disease patients.
    • Rigid plaster dressing and delayed casting are safe and do not compromise outcomes.
    • The long posterior flap is a superior surgical choice for improved wound healing in these patients.
