Scientific studies have been conducted to quantify attributes that may be important in the creation of more functional and comfortable lower-limb prostheses. The prosthesis socket, a human-machine interface, has to be designed properly to achieve satisfactory load transmission, stability, and efficient control for mobility. The biomechanical understanding of the interaction between prosthetic s...

Finite element method has been identified as a useful tool to understand the load transfer mechanics between a residual limb and its prosthetic socket. This paper proposed a new practical approach in modeling the contact interface with consideration of the friction/slip conditions and pre-stresses applied on the limb within a rectified socket. The residual limb and socket were modeled as two se...

Little research describes which transfemoral socket design features are important for coronal plane stability, socket comfort, and gait. Our study objectives were to (1) relate socket comfort during gait to a rank order of changes in ischial containment (IC) and tissue loading and (2) compare socket comfort during gait when tissue loading and IC were systematically manipulated. Six randomly ass...

PURPOSE The purpose of this study was to obtain anatomical information for installing four zygomatic implants, by measurements of maxillae and zygomata. MATERIALS AND METHODS Linear and angular measurements were obtained from the maxillae and zygomata of 40 dry skulls. RESULTS Based on mean and standard deviation values, the installation angle of the additional implant in the four zygoma te...

This paper describes a socket design and manufacturing technique for through-knee stumps, based on 14 years experience with 290 prostheses. The bulbous shape of the stump and its full end-bearing quality requires a socket which has very little resemblance to above-knee sockets. The requirements of the through-knee socket are listed and the manufacturing technique is described and illustrated in...

Prosthetics soft tissue trauma is attacked with a combination of theoretical and experimental tools . A novel socket design results, accentuating flesh stress relief at the socket brim . Currently, the novel socket has been fitted to two subjects with long histories of stump trauma ; field test results are not yet available.

In the ball type fracturing sliding sleeve, contact surface between socket and is most vulnerable part to failure. Once fails, sealing of sleeve will fail, fluid leak, finally fail. The condition mainly determined by cone angle socket. order improve as much possible, extend service life based on erosion finite element structural analysis, this paper has carried out analysis sleeve. Firstly, sea...

The distribution of interface stresses between the residual limb and prosthetic socket of a transtibial amputee has been considered as a direct indicator of the socket quality fit and comfort. Therefore, researchers have been very interested in quantifying these interface stresses in order to evaluate the extent of any potential damage caused by the socket to the residual limb tissues. During t...

We propose \MobileSocket", a new simple userlevel enhanced socket library written in pure-Java. MobileSocket provides Java applications with application layer mobility and connection continuity in order to support their continuous operation. Existing Java applications can attain socket-level mobility and connection continuity without any modi cation to their source code merely by replacing Java...
