Socket Geometry and Clinical Outcomes of Manual vs Digital Sockets for Lower-limb Amputees

During the shape-capturing in-patient appointment, participants will be measured for the prosthetic device through (1) manual casting using Plaster of Paris bandages and (2) scanning using a 3D scanner. The clinician will manually modify the positive plaster cast and digitally modify the scanned impression using OMEGA software. The manually-modified positive cast will be digitized by scanning the cast, then 3D-printed. The digitally-modified socket file will also be 3D printed. The research investigator will make a de-identified mark on each socket to differentiate between the two sockets after 3D printing, and will record the order in which the sockets are fit to the patient.
