In severe distal tibia, ankle, and foot trauma, decisions between limb salvage and amputation are governed primarily by systemic physiology, injury burden, and patient capacity to tolerate reconstruction, rather than limb anatomy alone. Advances in orthoplastic and microsurgical techniques have expanded salvage options, but critical illness, microcirculatory dysfunction, sepsis, and vasopressor dependence impose firm limits on reconstructive success. Traditional mangled extremity scoring systems lack sufficient sensitivity in contemporary practice and should function as adjuncts to clinical judgment rather than definitive decision tools. Large prospective cohorts demonstrate comparable long-term functional, quality of life, and psychological outcomes between salvage and transtibial amputation, with mortality driven by associated injuries rather than limb management strategy. Optimal outcomes depend on multidisciplinary coordination, judicious use of time-limited salvage trials, and shared decision-making that transparently weighs operative burden, rehabilitation trajectory, costs, access to care, and patient priorities.
