Composite hip prosthesis design. I. Analysis

Journal of Biomedical Materials Research, 1998
An investigation was performed to study the mechanical performance of fiber-reinforced composite hip prostheses in a femur. The main objective of the study was to evaluate the effect of fiber orientation of a composite femoral implant on the response of the surrounding femoral bone.

Composite hip prosthesis design. II. Simulation

Journal of Biomedical Materials Research, 1998
An investigation was performed to study the mechanical performance of fiber-reinforced composite hip prostheses. In Part I of the study, a three-dimensional finite element code was developed for analyzing a composite hip prosthesis in a femur. The material properties of the composite were treated as anisotropic and inhomogeneous while the properties of

Design of a total wrist prosthesis

Annals of Biomedical Engineering, 1984
Diseased wrist joints, in such cases as rheumatoid arthritis, are often required to be replaced by a prosthesis to relieve pain and to recover the wrist function. In designing this replacement, it is essential to understand the behavior of a normal wrist joint in its kinematic and kinetic aspects.

Socket modelling assistant for prosthesis design

International Journal of Computer Aided Engineering and Technology, 2013
In this paper, we propose a knowledge-based approach to design lower limb prostheses; in particular, we focus on the 3D modelling of the socket, the most critical component. First, the architecture of a dedicated design framework is described, detailing features of the main design steps.

Hip prosthesis: biomechanics and design

2022
Total hip arthroplasty is currently one of the most successful and frequently performed surgical procedures. The hip replacement operation is required if the joint is affected by severe osteoarthritis, which is known to lead to pain and limitations in the joint functions, especially when the patient is not responding to conservative treatments ...

Knee prosthesis: biomechanics and design

2022
Total knee arthroplasty (TKA) or total knee replacement (TKR) is, along with total hip arthroplasty, the most common prosthesis implanted by orthopedic surgeons; suffice it to say that both cover nearly 90% of orthopedic implants used. Nowadays, the global demand for TKA is increasing at an impressive rate due to the increasing prevalence of knee ...

Controllable Passive Transtibial Prosthesis - Design

2021
In medicine, a prosthesis or prosthetic implant is an artificial device that replaces a missing part of the body, which can be lost through trauma, disease, or illness present at birth. To help these amputated people, transtibial prostheses have been developed that have the role of increasing the motor abilities of the person in question.

An alternative design of extension prosthesis

Prosthetics & Orthotics International, 1987
Some patients with a congenitally shortened lower limb can be fitted with a total contact socket of one piece construction, dispensing with the need for removable panels or split socket construction. This gives advantages in weight, strength and cosmesis. The technique is described and compared with those conventionally used.

Design Optimization and Prosthesis Classification

2015
The evolution of reverse total shoulder arthroplasty (rTSA) is presented from a prosthesis design perspective along with the results of a design optimization analysis in which 32 different geometric iterations of the Grammont reverse shoulder were evaluated to identify parameters that minimize scapular impingement while maximizing range of motion and ...

Optimizing Ossicular Prosthesis Design and Placement

2018
Middle ear hearing reconstruction is unpredictable. Difficulties arise because of host factors, such as ventilation or scarring, surgical technique factors, such as prosthesis placement and stabilization, and design and mechanical factors influencing the properties of the prosthesis.
