This book was released on 2015 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The most important part of a trans-femoral prosthesis is the socket. It has to transfer the load generated during gait from the ground to the stump in a comfortable way. Several socket designs for trans-femoral amputees have appeared over the past half century, which have addressed many factors such as comfort, function and suspension. However, a totally satisfactory socket is still to be achieved. The present designs that are mostly used are the quadrilateral and ischial containment. Recently, a new transfemoral socket design has been proposed. It has been called the "High Fidelity" socket. According to the developers, this socket is claimed to provide a better connection with the femur, better suspension and comfort than current sockets. The aim of this research project was to assess the function of the high Fidelity trans-femoral socket relative to the ischial containment socket. This was done by measuring and comparing the pressure distribution at the stump/socket interface of the two socket designs, and recording the subjective views of the subject. Gait parameters (kinetic and kinematic) and the pressure distribution were measured simultaneously using the CAREN system (Computer Aided Rehabilitation Environment) technology and the Tekscan system in the gait analysis laboratory. A literature review of socket design and philosophies for trans-femoral amputation level prostheses was undertaken. It was found that the pressure distribution of the High Fidelity socket is more uniform than that of the ischial containment socket. The results captured were from one subject only because of the time limitation. The subject found that both sockets were comfortable. The acclimatization period for the High Fidelity socket was short.

This book was released on 2007 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two trans-tibial socket concepts are in regular use in prosthetic clinics. These may be categorised as the "hands-on" (hand casting) concept and "hands-off' (pressure casting) concept which, in addition to the distinctive casting methods, require different liner materials and components to create the desired loading distribution. Amputees have stated that quality of fit of the prosthetic socket is of highest importance, but, although pressure distribution has long been regarded as important, there is no general consensus regarding socket fit criteria. Furthermore, the casting process is carried out with the limb stationary. During walking the pressure distribution will change constantly throughout the gait cycle. The quality of fit of the prosthesis remains very subjective with little quantitative information regarding the pressure distribution within the socket. The aim of this study was to investigate and to compare the dynamic interface pressure distribution of the two socket concepts for a trans-tibial amputee population. In addition, the impact of the two socket concepts on their daily living activities was assessed. The objective was to relate measured pressure distribution to activity level and patient acceptance and thus increase understanding of what constitutes a good socket fit. The dynamic interface pressure distribution inside the socket of 48 patient's own prosthesis was recorded, using a validated pressure measurement system. The dynamic pressures recorded between the residual limb and the prosthetic socket showed similar distributions between the different casting concepts, although overall the hands-off sockets showed higher pressures than the hands-on group. The results from the questionnaire indicated that the quality of fit of the prosthetic socket had a strong correlation with user satisfaction. Results of this study have shown that the impacts of the two distinct prosthetic socket concepts have on the life of the amputee are very similar. Most of the participants used their prosthetic device regularly, and responded in similar ways regardless of the type of socket worn.

Available in PDF, EPUB and Kindle. Book excerpt: Foreword from a Clinical Biomechanist, Applied Physiologist and Prosthetist teaching graduate students in Prosthetics & Orthotics. While there are many books on Biomechanics, arguably the quintessential science of limb prosthetics, none addresses the fundamental principles in sufficient detail and depth to be practically useful to the prosthetist, rehabilitation specialist or researcher. Dr. Pitkin’s monograph is an exemplary collection of theoretical principles from his research and o- ers, presented in its clinical and applied biomechanics form. The textbook provides an excellent overview of the many facets of lower limb prosthetic design and engineering for the ardent clinician researcher and student. The book delves into many of the basic concepts that are required knowledge for the clinician and the scientist to have as the foundation for their work. Dr. Pitkin has an e- quent manner in which he reflects on the history and literature to tell the storied evolution of prosthetic design . He takes the reader on a journey to consider his theories, which have substantive foundations to contemplate. By the end of chapter one, we have the basic h- tory and an appreciation for the rationale behind the “rolling joint ankle” with evidence to support his theoretical views.

This book was released on 2018-02-08 with total page 87 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scientific Study from the year 2017 in the subject Medicine - Other, , language: English, abstract: This study presents analyses for below knee prosthetic socket of a human. Socket stress distribution is performed on three types of socket, polypropylene (5mm), polypropylene (3mm) and a standard laminate (3mm) sockets to determine the stresses path through the prosthetic socket during the gait cycle. It is found that heel strike phase is the critical phase. The stresses increase at the socket base while the maximum deflection is maximum at the patellar region of the socket. This work is achieved by finite element program, ANSYS. The development of design specifications of a below the knee prosthetic socket is presented in this study for successful ambulation and comfort. Seven different design models are created by changing the socket wall thickness and the material. Polypropylene socket gives the best results with regard to the allowable deflection for the regions of the pressure relief areas of the stump. The effect of varying the modulus of elasticity on the polypropylene socket is considered in this study. Three models are analyzed with different tensile creep moduli during different periods. It is found that the polypropylene socket will enlarge in size with time. An experimental study is conducted to compare the strength of five prosthetic sockets made of different materials. Compression, three-point flexural and tensile tests are implemented by the Testometric machine. The laminate sockets have larger compressive stiffness than polypropylene while polypropylene has larger flexural stiffness than the tested laminates except for socket No.5.
