Kenneth A. Kearns MD, Dan Witmer BS, Junaid Makda MD, Javad Parvizi MD, FRCS, Donald Jungkind PhD

Bacteria shed by operating room personnel is a source of wound contamination and postoperative infections. The personal protection system (PPS) was designed to decrease airborne bacteria and intraoperative contamination in total joint arthroplasty.

Molecular Techniques to Detect Biofilm Bacteria in Long Bone Nonunion: A Case Report

Michael Palmer MD, William Costerton PhD, Jeffrey Sewecke DO, Daniel Altman MD

Biofilms cause chronic infections including those associated with orthopaedic hardware. The only methods that are Food and Drug Administration-approved for detecting and identifying bacterial infections are cultures and selected DNA-based polymerase chain reaction methods that detect only specific pathogens (eg, methicillin-resistant Staphylococcus aureus). New DNA-based technologies enable the detection and identification of all bacteria present in a sample and to determine the antibiotic sensitivities of the organisms.
