21. Mechanical optimization of orthopaedic bone screw constructs
Abstract : Orthopaedic screw implants are crucial in surgical procedures for bone structures, with a longstanding issue being screw loosening. Improving screw stability requires an enhanced understanding of the bone-implant interactions and associated failure mechanisms. This knowledge can be used to optimize screw designs. READ MORE

22. Development of titanium-copper alloys for dental applications
Abstract : Titanium alloys find wide application in the medical implants industry, which includes areas of orthopaedic and dental implants. The reason for the popularity of the material is high mechanical strength, low density, and reported growth of bone onto the material, as well as corrosion resistance. READ MORE

23. Degradation Mechanism and Effects of Vitamin E addition in UHMWPE Hip Implants
Abstract : Wear of the UHMWPE component is one of the major concerns in joint replacement surgery, triggering prosthetic loosening leading to revision. The understanding of the mechanisms of material degradation, especially in regard to oxidation, is one of the keys to significantly improve the mechanical properties. READ MORE

24. Functional properties of silicon nitride based materials for joint applications
Abstract : Total hip and total knee replacements are generally successful procedures for patients suffering with pain due to bone fracture or diseases affecting the joints. However, the materials that are commonly used still have limitations. In particular, corrosion products and wear debris may give rise to negative body reactions. READ MORE

25. A clinical study of uncemented hip arthroplasty : radiological findings of host-bone reaction to the stem
Abstract : In total hip arthroplasty (THA), the main reason for failure leading to revision is aseptic loosening. Both mechanical and biological effects act in the loosening process, the factors may be implant design, fixation mode or technique, as well as biological factors unique to the individual. READ MORE
