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.

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.

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 ...

Knee prosthesis: biomechanics and design
2022Total 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
2021In 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, 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.

Design Optimization and Prosthesis Classification
2015The 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
2018Middle 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.

Total modular wrist prosthesis: a new design
Scandinavian Journal of Plastic and Reconstructive Surgery and Hand Surgery, 2004The common modes of failure of total wrist arthroplasty have been fracturing, loosening, pain on pronation and supination, and muscle soft-tissue imbalance. To overcome some of these problems a total modular wrist prosthesis has been designed for use both as a primary prosthesis and for revision surgery.

Biomechanical Design of the Total Ankle Prosthesis
Engineering in Medicine, 1983The load bearing joints of the human body and particularly the ankle are often seriously damaged because of different pathological events. During the last 10 years a lot of total ankle prostheses have been studied and implanted, in consequence of the inadequate results obtained by arthrodesis (i.e. the fusion of the joint).
