Conference Coverage: American Academy of Orthopaedic Surgeons 2012

The 2012 annual meeting of the American Academy of Orthopaedic Surgeons was held from February 7-11 in San Francisco. The features below highlight just some of the studies that emerged from the meeting. >> Analyzing Deep SSIs in Total Hip Arthroplasty >> Pain Following TKA Tied to Osteoarthritis >> Are Antibiotics Necessary for Clean Soft Tissue Hand Surgery? >> Defensive Medicine Costly in Orthopaedic Surgery >> Trending Lumbar Spinal Stenosis Surgery Analyzing Deep SSIs in Total Hip Arthroplasty The Particulars: Deep surgical site infections (SSIs) are severe complications that may occur in total hip arthroplasty (THA). Few studies have explored patient- and surgical-related risk factors for SSIs associated with THA. Data Breakdown: A prospective cohort study of 30,491 THA procedures found an incidence rate of 0.51% for deep SSIs. Patient factors associated with deep SSI were female gender, BMI of 30 kg/m2 or higher, and American Society of Anesthesiologist risk score of 3 or greater. Patient factors not associated with an increased risk of SSIs were age, arthritis diagnosis, diabetes, and race. Bilateral THA procedures were associated with a 5.32-times increased risk of SSIs when compared with unilateral THA procedures. Surgeon and hospital case volumes, use of antibiotic cement, fixation method, laminar flow, surgical approach, and fellowship training were not associated with SSIs. Take Home Pearl: Female gender, obesity, chronic medical conditions, and bilateral THA procedures appear to be associated with deep SSIs. Pain Following TKA Tied to Osteoarthritis The Particulars: Little is known regarding the association between objective ratings of preoperative osteoarthritis (OA) and pain and dissatisfaction following total knee arthroplasty (TKA). Data Breakdown: In a study, investigators...
