A clinical comparison of a digital versus conventional design methodology for transtibial prosthetic interfaces.

ABSTRACT: A transtibial prosthetic interface typically comprises a compliant liner and an outer rigid socket. The preponderance of today's conventional liners are mass produced in standard sizes, and conventional socket design is labor-intensive and artisanal, lacking clear scientific rationale. This work tests the clinical efficacy of a novel, physics-based digital design framework to create custom prosthetic liner-socket interfaces. In this investigation, we hypothesize that the novel digital approach will improve comfort outcomes compared to a conventional method of liner-socket design. The digital design framework generates custom transtibial prosthetic interfaces starting from MRI or CT image scans of the residual limb. The interface design employs FEA to simulate limb deformation under load. I
