Accurate pre-clinical evaluation of the initial stability of new cementless hip stems using in vitro micromotion measurements is an important step in the design process to assess the new stem's potential. Several measuring systems, linear variable displacement transducer-based and other, require assuming bone or implant to be rigid to obtain micromotion values or to calculate derived quantities such as relative implant tilting.

Name: Clinical biomechanics (Bristol, Avon)
This study aimed to correlate micromotion and gap measurements at the implant-abutment interface.
Although significant progress has been made in the development of total hip replacement, behaviour of the femoral component of an endoprosthesis in relation to the type of its fixation in the bone is ...
The purpose of the study was to observe changes in the skeletal system of rats with subclinical hypothyroidism (SCH) and to determine whether L-thyroxine (L-T4) administration suppresses those changes...
The purpose of this study is to investigate whether 1. the type of fixation at the shaft (hybrid vs. locking), 2. the position of the plate (offset vs. contact) and 3. the implant material has a signi...
Total hip arthroplasty is one of the most performed procedures in orthopaedic surgery. Implantation of a prosthesis determines changes in the distribution of loads on the host bone, and this phenomeno...
The primary focus of this study is to investigate whether increased bone density of the graft in revision arthroplasty of the hip can cause a decreased micromotion of the implant relative ...
The goal of this study is to compare the fixed bearing (FB) Triathlon knee (Stryker, USA) and the mobile bearing (MB) Triathlon knee (Stryker, USA) and study the effect of implant design o...
To document practices in Canadian ICD implant centres around defibrillation therapy efficacy testing.
Total knee arthroplasty is a frequent surgery in France. It currently represents 70,000 interventions per year. The total knee prosthesis is also called tri-compartmental because it allows...
Introduction: Kinetic, kinematic and electromyographic activity of the lower limb have been shown to be influenced by various footwear-generated biomechanical manipulations (e.g. soles. In...
Testing erythrocytes to determine presence or absence of blood-group antigens, testing of serum to determine the presence or absence of antibodies to these antigens, and selecting biocompatible blood by crossmatching samples from the donor against samples from the recipient. Crossmatching is performed prior to transfusion.
The detection of genetic variability (e.g., PHARMACOGENOMIC VARIANTS) relevant to PHARMACOGENETICS and PRECISION MEDICINE. The purpose of such genetic testing is to help determine the most effective treatment options and their optimum dosages with least potential risks for DRUG-RELATED SIDE EFFECTS AND ADVERSE REACTIONS.
Insertion of an implant into the bone of the mandible or maxilla. The implant has an exposed head which protrudes through the mucosa and is a prosthodontic abutment.
The constricted portion of the thigh bone between the femur head and the trochanters.
A quantitative form of intradermal testing for the relative allergenicity of a substance. It is used to determine the amount of an allergen that will be tolerated in ALLERGEN IMMUNOTHERAPY.
A joint is where two or more bones come together, like the knee, hip, elbow, or shoulder. Joints can be damaged by many types of injuries or diseases, including Arthritis - inflammation of a joint causes pain, stiffness, and swelling with ...
Osteoporosis is a disease in which the bones become extremely porous, are subject to fracture, and heal slowly, occurring especially in women following menopause and often leading to curvature of the spine from vertebral collapse. Follow and track&n...
