Background and aim: Traditional and advanced development methods of prosthetic sockets for limb amputations has been well investigated in the literature but some issues still remain with these procedures: previous experience of the prosthetist, large amount of waste material and hardware and software costs. The aim of the technical note was to propose a low-cost method for digitizing the residual limb and generate its corresponded prosthetic socket; and where the physical presence of the amputee is not a requirement. Technique: Three photographs are required as input to generate 2D profiles of the contour of the residual limb, which define its geometric shape, a 3D model is generated using standard CAD operations; and then, the prosthetic socket is generated using a sculpting software. Discussion: Experimental tests validated the prosthetic socket fit in a real case application; the generated prosthetic socket was comparable with the prosthetic socket currently used by the patient. The proposed method presents a virtual prosthetic socket design procedure that use open-source software and CNC low-cost hardware that facilitates its manufacturing; it also opens the possibility to generate prosthetic socket remotely.
