Prevention Of Surgical Site Infection: A Ten-Step Approach, Saad Tarabichi, Javad Parvizi

Rothman Institute Faculty Papers

Surgical site infection (SSI) is a common cause of morbidity and mortality in patients undergoing surgery. Similarly, periprosthetic joint infection (PJI), is a major cause of failure after total joint arthroplasty (TJA). As the annual volume of TJA procedures is projected to rise, so will the rate of subsequent SSI and PJI. Currently, prevention has been identified as the single most important strategy for combating SSI/PJI. Hence, the present article will serve as a summary of an evidence-based ten-step approach for SSI/PJI prevention that may help orthopedic surgeons with their infection prevention strategies.

Open Posterior Reduction And Stabilization Of Ao Spine C3 Sacral Fractures, Philipp Kobbe, Gregory D. Schroeder, Klaus J. Schnake, Lorin M. Benneker, Mark Lambrechts, Frank Hildebrand, Richard M. Sellei

Rothman Institute Faculty Papers

AO Spine C3 sacral fractures are defined by separation of the spine including S1 from the pelvic ring and are usually result of a high-energy injury. Besides their high biomechanical instability and high rate of associated neurological impairment, these fractures are often extremely difficult to reduce due to severe bony impaction and dislocation. Additional difficulties in management of these fractures arise from only a thin-layer of soft-tissue coverage overlying the injured area.
