C-reactive protein kinetics and its predictive value in orthopedic (trauma) surgery: A systematic review.

In Orthopedic Trauma Surgery (OTS), C-reactive- protein (CRP) is a widely used marker for the diagnosis of postoperative wound infections (POWI's) and other complications. The aim of this systematic review was to describe specific CRP kinetics and to evaluate the diagnostic value of CRP for te detection of post-operative complications in OTS. The same pattern is reported consistently, where the highest levels of CRP are found at post-operative-day two or three, returning to normal in three weeks. Amplitude varies per procedure. Persistently high CRP levels or secondary increases may indicate complications. A low CRP may be used to rule out complications.
