C5 - Prosthetic Free Papers - Foundations of Care: Sockets and Osseointegration

This session contains the following Free Papers

(C5A) Comparative Observational Study – Blind Test Hydrostatic Casting vs. Other Residual Limb Impression Methods
Presenter: Jeffrey A. Denune, CP, LP – Clinical Director of Prosthetic Research
This Pilot research will look at three shape-capture techniques to evaluate ADLs, Limb health, and comfort for Trans-Tibial amputees.

(C5B) Moisture Mitigation Using Perforated Liner and Socket System for Individuals with Trans-femoral Amputation
Presenter: Surya C. Gnyawali, MPhil, PhD – Assistant Professor, University of Pittsburgh, UPMC
The perforated socket-liner system mitigates the humidity hence the better prosthetic fit promoting better amputee life. Sweat build-up causes suboptimal socket fit and affects limb health and mobility.

(C5C) Limb Health and Socket Pressure in Response to Powered Ankle Prostheses
Presenter: Sashwati Roy, PhD – Professor of Surgery and Director of Clinical Research, Comprehensive Wound Center, University of Pittsburgh
This research seeks to understand and quantify the effects of powered transtibial prostheses on socket loading and direct measures of residual limb health.

(C5D) Socket Comfort Score: Comparing Current Transtibial Socket with Custom Direct Fit Socket
Presenter: Pamela Hale, CPO
A case study comparing a conventional transtibial carbon fiber socket to a custom direct-fit socket indicates that Socket Comfort Score and time to delivery are greatly improved with a direct-fit socket. With improved processes of fabrication, prosthetists can deliver a complete socket within 2 hours and eliminate multiple visits to the clinic for fittings.

(C5E) Osseointegration Outcomes Following Amputation
Presenter: Atiya Oomatia, BEng, MCT
This is the first study to directly address the outcomes, and management of osseointegration prosthesis following a limb lengthening procedure for individuals unable to use traditional socket prosthesis due to short stump.

(C5F) Individuals with Osseointegrated Prostheses Use an Intact Limb Reliance Strategy During Locomotion
Presenter: Jenna Burnett, MS, PhD – Post-doctoral Researcher, University of Utah
Individuals with lower limb amputation who use an osseointegrated prosthesis are expected to have improvements in their biomechanical performance due to the rigid connection between the prosthesis and the body. However, evidence suggests that individuals with a transfemoral amputa¬tion who use an osseointegrated prosthesis may use an intact limb reliance strategy during walking. This reliance on the intact limb may be due to muscle weaknesses, prosthesis component limitations, or behaviors previously adopted when using a socket.
