Can Early Post-Operative Scoring of Non-Traumatic Amputees Decrease Rates of Revision Surgery?

Area of Science:

• Medical Registries
• Surgical Outcomes
• Amputation Management

Background:

• Revision surgery rates after non-traumatic amputations are high, impacting patient rehabilitation.
• Existing risk scores for revision surgery after non-traumatic lower limb amputation are lacking.
• Medical registries are evolving into decision-making tools for patient care.

Purpose of the Study:

• To create an amputation registry for identifying risk factors for revision surgery.
• To develop a risk score for early detection of patients at risk for revision surgery.
• To aid in therapeutic decision-making for non-traumatic lower limb amputations and revision surgeries.

Main Methods:

• Retrospective analysis of 164 patients with major lower limb amputations over four years.
• Analysis of demographics, comorbidities, and amputation-related factors.
• Correlation analysis to identify parameters predicting revision surgery.

Main Results:

• 27% of non-traumatic amputations required revision surgery.
• Key risk factors identified include peripheral vascular disease, diabetes, delayed wound healing, prolonged hospital stay, and below-knee amputation (BKA).
• A novel scoring system was developed incorporating these risk factors.

Conclusions:

• Novel scoring systems for risk assessment in non-traumatic amputations and revision surgery have been described.
• The developed score can serve as an early-warning system for amputated limbs at risk of revision.
• Further prospective evaluation is recommended for clinical implementation.
