Joint replacement surgery—most commonly performed on hips and knees—has transformed the lives of millions by relieving pain, restoring movement, and improving quality of life. As technology advances, surgeons now have choices in how they fixate the prosthesis to the bone. The two primary techniques are cemented fixation and cementless fixation (also called uncemented fixation). ...
Medical rings, often referred to as marker bands, play a vital role in the field of medical devices. These small yet essential components are usually crafted from metals such as gold, platinum, or their alloys, providing radiopaque properties that allow them to be seen in X-ray imaging. This visibility is crucial in many minimally invasive surgical procedures, including angioplasty, where ...
Hip fractures are common, especially in older adults, and require timely medical and surgical intervention. These injuries can significantly impact a patient’s mobility, quality of life, and overall health. Hip fractures are a medical emergency, and delayed treatment can lead to severe consequences. Elderly patients are particularly vulnerable to complications from prolonged immobility, ...
Depending on the severity, osteoarthritis (OA) can be a seriously debilitating condition. This is particularly true when it takes effect on an individual’s hips or knees, joints that are essential for basic mobility. 2017 data published in the Annals of the Rheumatic Diseases by Saeid Safiri, PhD, of Tabriz University of Medical Sciences, and his colleagues, shows a consistent and ...
Plastic has been on the receiving end of a lot of bad publicity. A fair percentage of this is justified. There are, however, some environments where the benefits of plastics, even single-use plastics, far outweigh the disadvantages. The medical industry is one of them. Here are just some of the benefits of plastics in the medical industry.HygieneProbably the single, biggest benefit of plastics ...
We are celebrating a milestone of 2,000 cases, completed by Dr Kreuzer, with Intellijoint's navigation system.Intellijoint CEO, Armen Bakirtzian, sits down with Dr Kreuzer to discuss the benefits of navigation with the talented Orthopaedic surgeon. Armen Bakirtzian (AB): So, Dr. Kreuzer, 2,000 cases with Intellijoint. Firstly, a heartfelt congratulations and thank you from our entire team at ...
Are you considering hip replacement surgery? If you’re experiencing any signs that you might need a hip replacement, here are a few potential benefits of hip replacement surgery that you might want to discuss with your doctor. ...

Medical experts and sports scientists are becoming increasingly reliant on engineers as their disciplines become more and more technical. Mark Ingham looks at some of the projects his company, Sensor Technology, has helped behind the scenes. Like most rugby players I took my knees for granted until the day a twisting fall resulted in a torn anterior cruciate ligament. Fortunately these days it ...
In this study, it was shown that the concept of autonomic healing of a neat polymeric material, which was introduced by White et al. (2001) could be applied to poly methyl methacrylate (PMMA) bone cement. The bone cement brand used – Surgical Simplex®P – is one that is widely used in cemented arthroplasties; the healing agent used was 2.0 wt.% dicyclopentadiene (DCPD), encapsulated in poly ...
One of the primary reasons for joint replacement failure is fracture of the bone cement mantle. The objective of this study was to determine the effects of improving the dispersion of montmorillonite nanoclay in acrylic bone cement (by using coating technology) on the mechanical properties of the cured nanocomposite bone cement. Statistically significant improvements were found in the fracture ...
The principal mode of loosening of joint replacements is bone cement mantle failure, which is made worse with formation of microcracks under mechanical load. In this in vitro study the effect of incorporating montmorillonite nanoclay on the mechanical properties and morphology of bone cement was investigated. This study was conducted using a Design of Experiments (DOE) approach, which facilitated ...
