The analysis results showed that hydrostatic socket did exhibit more uniform pressure profiles than that of PTB socket. Three-dimensional models of both sockets were developed using MIMICS software. Both sockets' pressure profiles are studied and compared using finite element analysis (FEA) software. Thus, the hydrostatic socket which demands relatively lower level of fabricating skill is proposed to replace the PTB socket in order to produce the equivalent, if not better, quality of support to the amputee patients.

Lack of chartered and experienced prosthetist has often led to painful experience of wearing prosthesis and this will in turn deter the patients to wear the prosthesis, which will further aggravate stump shrinkage. However, this method would provide a viable 3D digital socket reproduction that is accessible and low-cost, after processing in prosthetic CAD software.Ĭonventionally, patellar tendon-bearing (PTB) sockets, which need high dexterity of prosthetist, are widely used. Discussion: 3D reconstruction accuracy averaged 2.6 ± 2.0 mm and 0.086 ± 0.078 L, which was less accurate than models obtained by high quality 3D scanners. Linear measurements were comparing between sockets and the related 3D models.

A 3D model is generated using cloud-based software. Technique: 15 two-dimensional images of the socket’s interior are captured using a smartphone camera. A low-cost and accessible photogrammetry method for socket interior digitization is proposed, using a smartphone camera and cloud-based photogrammetry services. While dedicated scanners exist, they are expensive and the cost may be prohibitive for a limited number of scans per year.

Background and Aim: Prosthetic CAD/CAM systems require accurate 3D limb models however, difficulties arise when working from the person’s socket since current 3D scanners have difficulties scanning socket interiors.
