Lower extremity prosthesis fit results from a complex biomechanical interaction at the interface between the residuum and socket. The quality of fit determines subject comfort, acceptance, and potential for ambulation. In situ static 3D determination of residual limb soft tissue changes due to the prosthesis socket by a new volumetric image-based mapping method was developed to aid in prosthesis design and evaluation. Volumetric imaging based on x-ray spiral CT was used for visualization of static in situ lower limb soft tissue changes without and with the prosthesis, including axial loading. The image volumes were registered using the tibial remnant from the below-knee residua so the paired volumes were superimposable. From the baseline and in situ prosthesis image volume data sets, limb remnant shape and prosthesis fit were visualized by 3D graphical display including cylindrically unwrapped depth shaded maps of the residual limb. Measurements, visualizations, and maps were obtained from spiral x-ray CT images to determine the soft tissue geometrical characteristics associated with prosthesis off and in situ, static axial loading, including a good and a poor fitting prosthesis. The feasibility of making quantitative measurements, visualizations, and maps from volumetric spiral x-ray CT data for use in fit evaluation was demonstrated.
