Understanding Functional and Hemodynamic Outcomes Across Lower Extremity Amputation Levels

Area of Science:

• Orthopedics
• Vascular Surgery
• Rehabilitation Medicine

Background:

• Lower extremity amputations (LEAs) significantly impact long-term functional capacity and cardiovascular health.
• Outcomes are highly variable depending on the level of amputation, affecting mobility, independence, and quality of life.

Purpose of the Study:

• To review current literature analyzing functional and cardiovascular outcomes across various lower extremity amputation levels.
• To elucidate outcome variations and suggest future research and clinical management directions.

Main Methods:

• Systematic literature review of outcomes across multiple LEA levels (hemipelvectomy to toe disarticulation).
• Analysis of factors influencing functional and cardiovascular adaptations post-amputation.

Main Results:

• Functional and cardiovascular outcomes correlate with retained body mechanics, joint function, and energy expenditure.
• Amputation increases risks for cardiovascular diseases (myocardial infarction, hypertension, aneurysm, PAD) and complications (infection, phantom limb pain, DVT).
• Higher amputation levels correlate with increased morbidity and mortality due to surgical complexity and complications.

Conclusions:

• Recognizing the impact of each LEA level is crucial for optimizing rehabilitation strategies.
• Tailored patient support and management based on amputation level are essential for improving quality of life.
