The Effect of Different Measurement-manufacturing Techniques on Load Distribution in Amputees

Marmara University30 enrolled

Overview

Alignment of the prosthesis with the stump is performed through the socket. Good socket stump fit provides near-normal posture and weight-transfer pattern. It also ensures that the walk is painless and low-energy. Recently, studies have been carried out to use 3D printers in socket production. 3D method is accepted as an effective and reliable method in prosthetic socket production. The purpose of this study is to compare the pressures distrubution in the sockets produced by conventional and 3D scanners and printers in the transtibial amputee.
