PERIOPERATIVE WOUND-INFECTION IN ELECTIVE ORTHOPEDIC-SURGERY

Between 1981 and 1987, 1207 consecutive open elective orthopaedic procedures were performed. The in-patient infection rate was 1·43%. There was a significantly greater risk of infection in revision total knee replacement (15·3%), ankle fusion (9·3%), subtalar fusion (5·8%), primary total knee replacement (5·7%), spinal fusion (5·7%) and revision total hip replacement (4·5%). Revision surgery carried approximately a threefold greater risk than primary procedures. Staphylococci were present in 83% of positive wound cultures. Infection rates varied among surgeons but when number and type of procedure were taken into account only two surgeons differed significantly from that expected. Patients undergoing spinal and hindfoot fusion suffered considerable morbidity as a consequence of wound infection. Antibiotic prophylaxis may be helpful in these procedures. © 1990.
