In the case of medical implants, foreign materials are preferential sites for bacterial adhesion and microbial contamination, which can lead to the development of prosthetic infections. Commercially biomedical TiNi shape memory alloys are the most commonly used materials for permanent implants in contact with bone and dental, and the prevention of infections of TiNi biomedical shape memory alloys in clinical cases is therefore a crucial challenge for orthopaedic and dental surgeons. In the present study, copper has been chosen as the alloying element for design and development novel ternary biomedical Ti‒Ni‒Cu shape memory alloys with antibacterial properties...

Orthopaedic device-related infections are closely linked to biofilm formation on the surfaces of these devices. Several modified titanium (Ti-6Al-4V) surfaces doped with fluorine were studied in order to evaluate the influence of these modifications on biofilm formation by Gram-positive and Gram-negative bacteria as well as a yeast. The biofilm studies were performed according to the standard test method approved by ASTM (Designation: E2196-12) using the Rotating Disk Reactor. Four types of Ti-6Al-4V samples were tested; chemically polished (CP), two types of nanostructures containing fluorine, nanoporous (NP) and nanotubular (NT), and non-nanostructured fluorine containing samples (fluoride barrier layers, FBL)...

BACKGROUND: Biologic agents have contributed significantly to the management of patients with in rheumatoid arthritis (RA). A significant proportion of patients with RA still require arthroplasty procedures however. It is unclear whether these agents increase the risk of post operative infection after lower limb arthroplasty . The aim of this review is to review the contemporary literature about this topic along with the recommendations from specialist societies. METHOD: A literature search was performed for articles published over the last 10 years in the English language examining the association between anti-tumour necrosis factor inhibitors and the incidence of post operative infection in patients with RA undergoing hip and knee arthroplasty procedures...

Prevention of infection and enhanced osseointegration are closely related, and required for a successful orthopaedic implant, which necessitate implant designs to consider both criteria in tandem. A multi-material coating containing 1:1 ratio of silicon-substituted hydroxyapatite and silver-substituted hydroxyapatite as the top functional layer, and hydroxyapatite as the base layer, was produced via the drop-on-demand micro-dispensing technique, as a strategic approach in the fight against infection along with the promotion of bone tissue regeneration...

In the current health care environment, cost containment is more important than ever. Most physicians currently are unaware of the cost of operating room supplies. A large amount of waste occurs secondary to lack of knowledge and absence of physician incentives for cost saving. Many of the decisions for supply use can be based on good scientific evidence, which supports specific cost saving measures. Careful attention to blood utilization and use of tranexamic acid has the potential to save millions in the hip fracture treatment and arthroplasty treatments...
