Abstract
Staphylococcus lugdunensis is a virulent coagulase-negative staphylococcus that behaves as S. aureus. S. lugdunensisosteoarticular infection were rarely reported.We report a series of the 119 cases of S. lugdunensisosteoarticular infection managed in 9 hospital centers and 3 private clinics in the South and the Southeastern of France. The median age of patients was 61 years with male-to-female sex ratio at 2.4. We have identified 94 cases (79%) of osteoarticular infectionassociated with orthopedic device including 2 cases of infection after anterior cruciate ligament reconstruction, 62 cases of prosthetic joint infections, 32 cases of internal orthopedic device infection and 3 cases of vertebral orthopedic device infection. Nine-percent of orthopedic device infection were occurred before the1st month afterthe implantation, 15% of cases between 1st-6th months and 52% of cases after the 6thmonths.We have identified 25 cases (21%) of bone and joint infection without orthopedic device including 4 cases of arthritis, 19 cases of osteitis and 2 cases of vertebral osteomyelitis without orthopedic device.Seventy-six percent of cases were treated by surgery including 39% of cases by lavage and debridement, 24% by orthopedic device removal and 17% prosthesis removal. Amputation has been observed in 8% of cases. The remission was observed in 67% of cases; whereas the relapses were observed in 14% of cases. S. lugdunensisosteoarticular infectionis an underestimated hospital-acquired infection which are often associated with orthopedic devices. The orthopedic devices must be removed to control infections embedded in biofilm.
