Most traumatic lower limb amputees ambulate using a prosthetic limb. Comfort, appearance of the missing limb and function are confirmed as being important during rehabilitation post-amputation. Emerging evidence suggests that impaired tissue viability of the stump affects rehabilitation and thus clinical ability to provide optimum care. The primary objective of this systematic review was to identify key factors relating to tissue viability of the residual limb in lower extremity traumatic amputees. A secondary objective was to identify factors that affect rehabilitation post-amputation. In total, 218 studies were assessed; 37 met pre-determined criteria. Studies were classified according to the WHO ICF framework and the NHMRC level of evidence. Five key themes emerged; Prosthetic Fit; The Residuum; Quality of Life; Amputee Care and Prosthetic Use. The evidence indicates that high frequencies of skin problems affecting tissue viability within this population are inherently linked to intolerance of the prosthesis. Stump integrity, amputee care regimen and pain were also identified as impacting on quality of life, affecting rehabilitation and the ability to become independently mobile. Levels of evidence within all studies were low and indicative of the majority being non-randomised cohort studies or case-control studies. As there are a limited number of interventional studies, further development of robust outcome measures, clinical trials and prospective studies are of utmost importance to unravel the links between tissue viability and the other key factors. This will inform clinical management strategies and help develop targeted therapies and care pathways.
