Assessment follows a structured approach evaluating bone injury severity, soft tissue damage, vascular status, nerve function, and patient factors. Scoring systems (MESS, LEAP criteria) provide guidance but do not dictate the decision. The assessment includes: vascular status — is there blood flow to the foot/hand? Nerve function — is the tibial/posterior interosseous nerve intact? Soft tissue — can adequate coverage be achieved? Bone — can the skeleton be reconstructed? Patient factors — age, comorbidities, smoking, occupation, patient wishes. The decision is made by a senior multidisciplinary team including orthopaedic, vascular, and plastic surgeons.
Formal assessment is required for all Gustilo type IIIB and IIIC open fractures, crush injuries with prolonged ischaemia, blast injuries, and any limb where viability is in question. The decision between salvage and amputation profoundly affects the patient's life and must be made carefully.
This is a decision-making process, not a procedure. The outcome is either limb salvage (with extensive reconstruction) or amputation.
Emergency assessment. Vascular status is the most time-critical factor — warm ischaemia beyond six hours dramatically reduces salvage success. Photography of the injury. Senior review.
A well-informed decision that gives the patient the best functional outcome. Evidence from the LEAP study shows that functional outcomes two years after salvage versus amputation of severe lower limb injuries are similar — the quality of the decision and the rehabilitation are more important than the decision itself.
UncertaintyExpected
The decision is often not clear-cut. Multiple factors must be weighed.
Emotional burdenExpected
The decision profoundly affects the patient and their family.
Salvage may failUncommon
Attempted salvage may ultimately fail, requiring secondary amputation — which has worse outcomes than primary amputation.
Secondary amputationUncommon
If salvage fails after prolonged treatment. Poorer outcomes than primary amputation.
Chronic painCommon
Both salvage and amputation carry risk of chronic pain.
Psychological morbidityCommon
Depression, PTSD, and adjustment disorder are common after major limb trauma.
Assessment is clinical. Surgical intervention (salvage or amputation) requires general anaesthesia.
Recovery depends entirely on the chosen pathway. Salvage: multiple operations over months, prolonged rehabilitation, twelve to twenty-four months to maximum improvement. Amputation: prosthetic fitting at six to eight weeks, gait training, maximum improvement at twelve to eighteen months. Both pathways require intensive physiotherapy and psychological support.
Intensive multidisciplinary follow-up for both pathways. Psychological support. Regular assessment of function and quality of life.
Is amputation always worse than salvage?
No. The LEAP study showed that functional outcomes at two years are similar for salvage and amputation of severe lower limb injuries. A well-functioning amputation with a modern prosthesis can be superior to a chronically painful, stiff salvaged limb. The best outcome depends on individual circumstances.
Who makes the decision?
The decision is made collaboratively by the patient (when conscious and able) and a senior multidisciplinary team. The patient's wishes, occupation, activity level, and overall health are central to the discussion.
What is the MESS score?
The Mangled Extremity Severity Score (MESS) considers skeletal/soft tissue injury, limb ischaemia, shock, and patient age. A score of 7 or above has historically been considered predictive of amputation, but it has significant limitations and should not be used in isolation.
