Probabilistic Design of a Newly Designed Cemented Hip Prosthesis Using Finite Element Method

Materials & Design, 2008
The finite element method is an important tool used in the design of orthopedic prosthesis. One of the important orthopedic applications is hip prosthesis replacement. This operation is so complex that it requires close co-operation between engineers and

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 ...

Design of an Intervertebral Disc Prosthesis

Spine, 1991
This 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 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.

Design of an underactuated prosthesis arm

2016 6th IEEE International Conference on Biomedical Robotics and Biomechatronics (BioRob), 2016
In 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, 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.

Topological optimization in hip prosthesis design

Biomechanics and Modeling in Mechanobiology, 2009
With 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, 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 and characterization of a powered elbow prosthesis

2015 37th Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC), 2015
This paper describes the design of a powered elbow prosthesis, which incorporates a belt and cable drive transmission with a brushless DC motor to achieve an output torque of approximately 18.4 Nm, a backdrive torque of 1.5 Nm, and a speed of up to 360 deg/s while remaining within the anthropomorphic envelope with regard to mass and size.
