A Structured 3-Chart Clinical Reference Set. This three-chart set integrates anatomical amputation levels with prosthetic pressure distribution principles into one coherent visual system. The central chart presents clearly defined upper and lower limb amputation levels, ranging from partial foot to forequarter disarticulation. Flanking charts map pressure-sensitive and pressure-tolerant areas of the residual limb, providing essential context for prosthetic socket design and load management.
