A New Cemented Hip Prosthesis Concept [PDF]

Journal of Medical Devices, 2011
The orthopedic market offers more than 200 hundred different femoral stems, some with scientific published results. The influence of stem geometry relatively to stress distribution on the cement mantle has been addressed by some authors. Stem geometry influences the fatigue mechanism process at the stem-cement interface and may cause aseptic loosening.

Higher surgeon volume reduces early failure in first time revision of non‐infected total knee arthroplasty: An analysis using data from the United Kingdom National Joint Registry

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Revision total knee replacement (RevKR) is an increasingly common procedure. It is hypothesised that higher surgical volume is linked to lower levels of adverse outcomes. The aim was to estimate the association of surgical volume on patient outcomes following first single‐stage RevKR for non‐infected indications.

Influence of cementless hip stems on femoral cortical strain pattern depending on their extent of porous coating [PDF]

, 2012
The extent of porous coating of cementless total hip stems is held responsible for radiological periprosthetic changes, the rate of thigh pain, and even its long-term success.

Hip arthroscopy and periacetabular osteotomy generally improve sexual function in patients, but have a risk of iatrogenic pudendal nerve injury that can temporarily worsen sexual function: A systematic review

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
ABSTRACT Purpose To summarise how orthopaedic hip sports medicine procedures affect patients' sexual function so that surgeons can better counsel their patients on this topic. Methods Three databases (MEDLINE, EMBASE and PubMed) were searched on 27 April 2024 with search terms relating to sexual activity and orthopaedic procedures.

A Phase Variable Approach for Improved Rhythmic and Non-Rhythmic Control of a Powered Knee-Ankle Prosthesis [PDF]

arXiv, 2018
Although there has been recent progress in control of multi-joint prosthetic legs for rhythmic tasks such as walking, control of these systems for non-rhythmic motions and general real-world maneuvers is still an open problem. In this article, we develop a new controller that is capable of both rhythmic (constant-speed) walking, transitions between ...

Advancements in Magnesium Applications, Biocompatible Implants to Nanoparticles in Medicine and Biomedical Innovations

MetalMat, EarlyView.
Magnesium (Mg) and its alloys are identified as prospective materials for orthopedic and cardiovascular applications because of their bio‐corrosiveness and ability to stimulate tissue reparative processes. Although compared with traditional metals, Mg is biocompatible; however, it has various problems that stem from its biodegradation nature, for ...

A novel concept for the manufacture of individual sapphire-metallic hip joint endoprostheses. [PDF]

, 2006
At the present time, artificial joints made with metallic, ceramic, metal-polymeric or ceramicpolymeric friction pairs substituting for the natural biomechanic articulations "head of the hip joint-acetabulum" are widely used for endoprosthetic ...

Viscoelasticity Estimation of Sports Prosthesis by Energy-minimizing Inverse Kinematics and Its Validation by Forward Dynamics [PDF]

Advanced Robotics, 2024, 1-13
In this study, we present a method for estimating the viscoelasticity of a leaf-spring sports prosthesis using advanced energy minimizing inverse kinematics based on the Piece-wise Constant Strain (PCS) model to reconstruct the three-dimensional dynamic behavior.
