Factores de riesgo e infección del sitio quirúrgico en procedimientos de cirugía ortopédica con prótesis

Risk factors related to surgical site infection in orthopedic prosthesis surgery Objective: to identify the risk factors for surgical site infections (SSI) in patients with surgical management fractures with internal fi xation or prosthetic material. Materials and Methods: a cross-sectional study was conducted in a tertiary institution in Armenia-Colombia in 2008 and 2009 in 223 patients. Results: The superfi cial incisional infection frequency was 9,4% (n: 21), and deep incisional infection was 7,6% (n: 17); there were no organ/space SSI.; the highest rates of infection were observed in patella fractures (50%), acromio-clavicular joint (25%), and femur (23,7%). The infections were caused by: S. aureus, Enterobacter gergoviae y Enterobacter aerogenes. There was an association with clean-contaminated wounds compared to clean wounds (OR 2,2), comminuted fractures (OR 2,1) multiple fractures (OR 2,9) and patella surgery (OR 3,1). Conclusions: the severity of the fracture and the degree of contamination were predisposing factors to infection.
