“…The optimized material-model combination enhanced the functional capabilities and consequently, was expected to reduce the need for resection among younger patients (Kumar and Sarkar, 2018). In addition, researches on various model designs are also available in different types of research (Minnoye and Plettenburg, 2009; Vertullo et al , 2018). This study has attempted to create the ideal knee prosthesis design geometry.…”

Purpose This study aims to design a femoral component with minimum volume and maximum safety coefficient. Total knee prosthesis is a well-established therapy in arthroplasty applications. And in particular, with respect to damaged or weakened cartilage, new prostheses are being manufactured from bio-materials which are compatible with the human body to replace these damages. A new universal method (design method requiring optimum volume and safety [DMROVAS]) was propounded to find the optimum design parameters of tibial component. Design/methodology/approach The design montage was analyzed via the finite element method (FEM). To ensure the stability of the prosthesis, the maximum stress angle and magnitude of the force on the knee were taken into consideration. In the analysis process, results revealed two different maximum stress areas which were supported by case reports in the literature. Variations of maximum stress, safety factor and weight were revealed by FEM analysis, and ANOVA was used to determine the F force percentage for each of the design parameters. Findings Optimal design parameter levels were chosen for the individual’s minimum weight. Stress maps were constructed to optimize design choices that enabled further enhancement of the design models. The safety factor variation (SFV) of 5.73 was obtained for the volume of 39,219 mL for a region which had maximum stress. At the same time, for a maximum SFV and at the same time an average weight, values of 37,308 mL and 5.8 for volume and SFV were attained, respectively, using statistical methods. Originality/value This proposed optimal design development method is new and one that can be used for many biomechanical products and universal industrial designs.

“…Snowboarding, due to the particular position of the snowboarder's legs, requires a greater degree of movement in the ankle than skiing. 28 Because of this, a specially designed ankle unit that allows plantar flexion and dorsiflexion as well as inversion and eversion has been shown to be more useful than regular prosthetic ankles for snowboarding. 28…”

Background:Sport prostheses are used by both upper- and lower-limb amputees while participating in sports and other physical activities. Although the number of these devices has increased over the past decade, no overview of the peer reviewed literature describing them has been published previously. Such an overview will allow specialists to choose appropriate prostheses based on available scientific evidence rather than on personal experience or preference.Objective:To provide an overview of the sport prostheses as they are described by the papers published in peer reviewed literature.Study Design:Literature review.Methods:Four electronic databases were searched using free text and Medical Subject Headings (MESH) terms. Papers were included if they concerned a prosthesis or a prosthetic adaptation used in sports. Papers were excluded if they did not originate from peer reviewed sources, if they concerned prostheses for body parts other than the upper or lower limbs, if they concerned amputations distal to the wrist or ankle, or if they were written in a language other than English.Results:Twenty-four papers were included in this study. The vast majority contained descriptive data and consisted of expert opinions and technical notes.Conclusion:Data concerning the energy efficiency, technical characteristics and special mechanical properties of prostheses or prosthetic adaptations for sports, other than running, are scarce.Clinical relevanceAn overview of the peer reviewed literature will enable rehabilitation specialists working with amputees to choose a prosthesis that best suits their patients’ expectations on the available scientific evidence. Identifying the information gaps present in the peer reviewed literature will stimulate new research and eventually broaden the base of scientific knowledge.

“…It can also be a good alternative to metal when filled with glass fibre [22]. It can also be used in medicine, including in limb prosthesis processes for various types of prostheses: cosmetic [23] and functional [24][25][26], including kinetic, myoelectric and bionic prostheses. The currently produced functional prostheses are always heavier than cosmetic prostheses, which require a disabled person to change the habits acquired during the use of cosmetic prostheses.…”

Mechanical Reinforcement of Polyamide 6 by Cold Hydrostatic Extrusion

et al. 2021

This paper presents the effect of severe plastic deformation obtained using the cold hydrostatic extrusion (HE) method on the mechanical and structural properties of polyamide 6 (PA6). As a result of the plastic strain, a significant increase in ultimate tensile strength and tensile modulus were observed. Tensile strength rose by almost 500%, up to the level of 508 MPa, whereas the tensile modulus rose by about 65%. Flexural modulus increase was also observed to 3230 MPa, i.e., by approx. 160%. As a result of high plastic deformation, the structure of the polyamide 6 changed significantly, as evidenced by its fibrous nature as presented in the results of the scanning electron microscopy inspection (SEM). The surface quality of products investigated was tested using profilometry.
