Cyanoacrylate Microbial Sealant May Reduce the Prevalence of Positive Cultures in Revision Shoulder Arthroplasty
Cyanoacrylate-based, microbial sealant is an adhesive skin barrier designed to prevent bacterial contamination in surgical wounds. This type of adhesive barrier could have use in decreasing the incidence of positive cultures and subsequent infection in shoulder arthroplasty.
Local delivery is required to achieve the high antimicrobial concentrations needed to treat biofilm-forming infections. The delivery site is commonly either in the intramedullary canal or at the periosteal surface. It is unknown whether locally delivered antimicrobials are transported transcortically between the endosteal and periosteal surfaces when the infection involves the opposite surface.
Infection about a megaprosthesis is a dreaded complication. Treatment options vary from débridement alone to staged revisions, arthrodesis, and amputation. Indications for how to treat this complication are unclear.
Hospital-acquired infections caused by methicillin-resistant(MRSA) are a source of morbidity and mortality.is the most common pathogen in prosthetic joint infections and the incidence of MRSA is increasing.
It is common practice in many centers to avoid performing a clean case in a room in which an infected procedure has just taken place. No studies of which we are aware speak to the necessity of this precaution.
Methicillin-resistant Staphylococcus aureus infections are a well-documented risk of surgery and are becoming increasingly difficult to treat owing to continued acquired resistance. A new antibiotic for treatment of Staphylococcus aureus is telavancin.
Previous studies have found fewer clinical infections in wounds closed with monofilament suture compared with braided suture. Recently, barbed monofilament sutures have shown improved strength and increased timesavings over interrupted braided sutures. However, the adherence of bacteria to barbed monofilament sutures and other commonly used suture materials is unclear.
The role of the synovial biopsy in the preoperative diagnosis of a periprosthetic joint infection (PJI) of the hip has not been clearly defined.
Sonication and scraping of infected prostheses usually are used to improve diagnosis of prosthetic infections, reducing false negatives. Chemical methods that reduce biofilms also may allow higher levels of detection.
Enterococcal periprosthetic joint infections (PJIs) are rare after joint arthroplasty. These cases are usually reported in series of PJIs caused by other pathogens. Because few studies have focused only on enterococcal PJIs, management and control of infection of these cases have not yet been well defined.
