    This study reports on 312 lower-extremity amputations for ischemia over eight years. Key findings include 75% primary healing rates and 6% mortality, emphasizing limb preservation strategies.

    Area of Science:

    • Vascular Surgery
    • Orthopedic Surgery
    • Rehabilitation Medicine

    Background:

    • Lower-extremity amputations are frequently performed due to ischemia.
    • Optimizing amputation level and healing is crucial for patient outcomes and prosthesis use.
    • Evaluating new amputation techniques requires comprehensive institutional data.

    Purpose of the Study:

    • To report the comprehensive eight-year experience with 312 lower-extremity amputations for ischemia.
    • To identify factors contributing to successful amputation healing and limb preservation.
    • To advocate for reporting total institutional amputation data for accurate evaluation.

    Main Methods:

    • Retrospective review of 312 lower-extremity amputations performed over eight years.
    • Analysis of amputation healing rates, need for prosthesis, knee joint preservation, and mortality.

  • Identification of factors such as prior arterial reconstruction and wound care.

    • Main Results:

    • Overall primary amputation healing rate was 75%.
    • Knee joint preservation was achieved in 72% of cases.
    • Amputation requiring no prosthesis was achieved in 31% of patients, with a 6% mortality rate.

    Conclusions:

    • Prior arterial reconstruction, meticulous wound care, and accepting trial amputation nonhealing are vital for distal healing.
    • Comprehensive reporting of all institutional amputation cases is necessary for accurate assessment of new methods.
    • The study highlights the importance of a holistic approach to lower-extremity amputation for improved patient function and reduced morbidity.
