Comparing the Ultimate Strength of 3D Printed and Laminated Sockets

Noah Rosenblatt, PhD

3D printing is a robust tool for fabricating complicated objects in a cost-effective and timely manner. Limited information on strength of 3D printed sockets (3DS) may curtail their adoption as definitive sockets in the US. Systematic review results conducted by our group found that failure forces of 3DS trended towards those observed in laminated sockets. We performed ultimate failure testing of 3DS using some of the latest filaments available and compared results to those of a standard laminated composite socket.

Comparative Observational Study - Blind Test Hydrostatic Casting vs. Other Residual Limb Impression Methods

Jeffrey A. Denune CP/L, CP/L

Hydrostatic casting while bearing full body weight is an alternative to traditional casting impression methods in providing for trans-femoral and trans-tibial amputees. Previous research related to the new method have shown positive results in regard to the patient's acceptance, the limited number of necessary modifications and the high amount of successfully produced sockets. For this pilot study, the application and fit of the sockets in relation to, proprioception, the mastering of a distance and the length of distance, as well as the patient's subjective perception were examined and the results were compared to other residual limb impression methods.

Preliminary Findings from a Clinical Trial of Adjustable Volume Transfemoral Sockets

Deanna H. Gates, PhD

This presentation will discuss preliminary findings from a clinical trial of assessing three different styles of adjustable-volume prosthetic sockets in individuals with transfemoral amputation. We will present findings on patient comfort, activity in daily life and performance during functional assessments.
