Extended-Spectrum Beta-Lactamase Infections in Orthopedic-Related Devices and Prosthetic Joints.

Extended-spectrum beta-lactamase-producing Enterobacteriaceae have increasingly become a public health issue in a variety of infections, including urinary tract infections and postoperative infections. The complications that occur due to these organisms in bone, joint, and prosthetic joints have not been well defined. This study reviewed the clinical characteristics, risk factors, and outcomes of patients with extended-spectrum beta-lactamase-producing Enterobacteriaceae infections of prosthetic joints or orthopedic-related hardware. Six infections met the inclusion criteria that resulted in a 100% failure rate when the hardware or prosthetic joint was not replaced initially. However, when the hardware or prosthetic joint was replaced, all of the patients did well. The use of carbapenems remains effective in these cases. [Orthopedics. 2016; 39(4):e668-e673.].
