BACKGROUND: Lower extremity amputations (LEAs) significantly alter an individual's long-term functional capabilities and cardiovascular health. These outcomes vary significantly across LEA levels, affecting mobility, independence, and overall quality of life.
METHODS: This article reviews current literature to analyze these outcomes across different LEA levels including hemipelvectomy, hip disarticulation, above-knee amputation, knee disarticulation, below-knee amputation, Syme amputation, Chopart amputation, Lisfranc amputation, and toe disarticulation to elucidate outcomes, understand variations, and suggest directions for future research and informed clinical management.
RESULTS: Although mechanical and hemodynamic systems undergo significant adaptations following all levels of LEA, improved functional and cardiovascular outcomes are a direct result of retained body mechanics, preservation of joint function, and the degree of energy expenditure. Surgical severing of blood vessels and increased effort to effectively supply oxygenated blood throughout the body substantially raise the risk of developing diseases such as myocardial infarction, hypertension, aortic aneurysm, and peripheral arterial disease. Patient comorbidities not only necessitate amputation but also remain factors impacting wound complications, morbidity, mortality, and reamputation rates. Morbidity and mortality rates are notably high for higher level amputations due to the complexity of the surgery and the associated risk of complications. Complications such as infection, phantom limb pain, and deep vein thrombosis vary greatly by level of amputation and often present alongside markers of hemodynamic instability and shock.
CONCLUSIONS: Recognizing the effects of each LEA level on patient quality and function of life is crucial for optimizing rehabilitation strategies and providing comprehensive patient support.
