Finite element modelling of shock-induced damages on ceramic hip prostheses [PDF]

open access: yesISRN Materials Science (2011) ID 121486, 2012
The aim of this work was to simulate the behaviour of hip prostheses under mechanical shocks. When hip joint is replaced by prosthesis, during the swing phase of the leg, a microseparation between the prosthetic head and the cup could occur. Two different sizes of femoral heads were studied: 28 and 32 mm diameter, made, respectively, in alumina and ...

The Needs of Current Implant Technology in Orthopaedic Prosthesis Biomaterials Application to Reduce Prosthesis Failure Rate

open access: yes, 2016
Today, orthopaedics is still in search for the most reliable biomaterial for prosthesis. The biomaterial needs to have good longevity and other supporting properties in order to maintain low implant failure.

Automatic Identification of Failure in Hip Replacement: An Artificial Intelligence Approach

open access: yesBioengineering, 2022
Background: Total hip arthroplasty (THA) follow-up is conventionally conducted with serial X-ray imaging in order to ensure the early identification of implant failure.

Finite element analysis of porously punched prosthetic short stem virtually designed for simulative uncemented hip arthroplasty [PDF]

open access: yes, 2017
Background: There is no universal hip implant suitably fills all femoral types, whether prostheses of porous short-stem suitable for Hip Arthroplasty is to be measured scientifically.

Penile Prosthesis in Transgender Men after Phalloplasty

open access: yesIndian Journal of Plastic Surgery, 2022
A penile prosthesis can be successfully implanted after phalloplasty in transgender men to permit sexual intercourse. A prosthesis can be categorized as malleable or inflatable.

Haptic Shared Control Improves Neural Efficiency During Myoelectric Prosthesis Use [PDF]

open access: yes, 2022
Clinical myoelectric prostheses lack the sensory feedback and sufficient dexterity required to complete activities of daily living efficiently and accurately. Providing haptic feedback of relevant environmental cues to the user or imbuing the prosthesis with autonomous control authority have been separately shown to improve prosthesis utility.

Aseptic loosening of total hip replacement. Macrophage expression of inducible nitric oxide synthase and cyclo-oxygenase-2, together with peroxynitrite formation, as a possible mechanism for early prosthesis failure.

open access: yesJournal of Bone and Joint Surgery-british Volume, 1997
Aseptic loosening is a major cause of failure of total hip arthroplasty. The adverse tissue response to prosthetic wear particles, with activation of cytokine and prostanoid production, contributes to bone loss around the implants.

Multi-energy spectral photon-counting computed tomography (MARS) for detection of arthroplasty implant failure

open access: yesScientific Reports, 2021
To determine whether state-of-the-art multi-energy spectral photon-counting computed tomography (MARS) can detect knee arthroplasty implant failure not detected by standard pre-operative imaging techniques.
