Zn and Zn-based alloys have been recognized as highly promising biodegradable materials for orthopedic implants and cardiovascular stents, due to their proved biocompatibility and, more importantly, lower corrosion rates compared to Mg alloys. However, pure Zn has poor mechanical properties. In this study, Ag is used as a promising alloying element to improve the mechanical properties of the Zn matrix as well as its biocompatibility and antibacterial properties. Accordingly, we design three ZnAg alloys with Ag content ranging from 2...

Rheumatoid arthritis (RA) is a chronic, systemic autoimmune disorder known to cause progressive joint destruction. Over time, untreated RA can lead to pain and increasing disability, making orthopedic intervention necessary. The treatment of RA revolves around a variety of medications that blunt the overall immune response. However, this may increase the risk of infection and impair wound healing. Given the nature of this disease, orthopedists frequently encounter patients with RA in the operative setting. To optimize surgical outcomes, orthopedists must carefully manage and pay special attention to the adverse side effects of the complicated medication regimens of these patients perioperatively...

REVIEW
Andrew N Fleischman, Matthew S Austin
Surgical site infection (SSI) is one of the most common complications after orthopaedic surgery, leading to significant morbidity and its associated costs. Surgical guidelines strongly recommend the use of systemic antibiotic prophylaxis to reduce the risk for developing SSI. Locally administered powdered antibiotics have the potential to provide remarkably high intra-wound concentrations without risk for systemic toxicity. However, a paucity of high quality evidence in the orthopaedic literature has prevented widespread adoption of this technique...
