Clinical algorithm for NU-FlexSIV Socket. Regarding liner selection, almost all transfemoral limb shapes can be made more cylindrical by fitting an off-the-shelf transtibial liner; custom liners are only required when the limb is heavily scarred or bulbous. The manner in which the liner is customized should ensure that the liner clad limb shape is cylindrical. “Gradated reductions” refer to the reduction of circumferences more proximally than distally. For example, for 6%–4% reductions, the circumferences in the proximal third of the limb are reduced by 6%, the circumferences in the middle third of the limb are reduced by 5%, and the circumferences in the lower third of the limb are reduced by 4%.
