The mangled extremity: assessment, decision making and outcomes

The management of the mangled extremity continues to pose a significant challenge for orthopaedic trauma surgeons. This article provides a comprehensive, up-to-date literature review on the assessment of complex limb injuries, and the variables that affect decision-making and outcomes in both limb salvage and amputation. Initial assessment involves using a systematic approach, saving life before limb, with early involvement of the relevant surgical specialities and multidisciplinary team. The decision to attempt limb salvage or perform amputation can be extremely difficult. Scoring systems can be used as a guide but should not be wholly relied upon; instead more emphasis should be placed on the surgeon's experience, extent of soft tissue damage, and patient factors and wishes. Outcomes following amputation versus limb salvage are comparable, with some studies suggesting amputation may be favourable. It is important to advise patients and families on what treatment is in their best interest so they can make an informed decision, and this must utilise a multidisciplinary approach.
