Hip prosthesis: biomechanics and design
2022Total 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 ...

Design of an Intervertebral Disc Prosthesis
Spine, 1991This article presents criteria for the design of a lumbar intervertebral disc prosthesis that take into consideration issues of endurance, materials behavior, geometry, kinetics, motion constraints, fixation to bone, and safety. The criteria and design philosophies discussed are generally applicable in the synthesis of any new implant system ...

Design and Control of a Powered Transfemoral Prosthesis [PDF]
International Journal of Robotics Research, 2008 The paper describes the design and control of a transfemoral prosthesis with powered knee and ankle joints. The initial prototype is a pneumatically actuated powered-tethered device, which is intended to serve as a laboratory test bed for a subsequent self-powered version. The prosthesis design is described, including its kinematic optimization and the

Design of a total wrist prosthesis
Annals of Biomedical Engineering, 1984Diseased 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.

Design of an underactuated prosthesis arm
2016 6th IEEE International Conference on Biomedical Robotics and Biomechatronics (BioRob), 2016In motion design of a prosthesis arm, number of actuators is considered the most crucial part. The higher number of actuator allows us to have many degree of freedom while results in the heavy weight of the device. In the past, motors and pneumatic systems are commonly used as actuators for prosthesis devices.

Socket modelling assistant for prosthesis design
International Journal of Computer Aided Engineering and Technology, 2013In 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.

Topological optimization in hip prosthesis design
Biomechanics and Modeling in Mechanobiology, 2009With particular interest on total hip arthroplasty (THA), optimization of orthopedic prostheses is employed in this work to minimize the probability of implant failure or maximize prosthesis reliability. This goal is often identified with the reduction of stress concentrations at the interface between bone and these devices.

An alternative design of extension prosthesis
Prosthetics & Orthotics International, 1987Some 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.

A digital patient for computer-aided prosthesis design [PDF]
Interface Focus, 2013 This article concerns the design of lower limb prosthesis, both below and above knee. It describes a new computer-based design framework and a digital model of the patient around which the prosthesis is designed and tested in a completely virtual environment.
