Emerging strain of Stapylococcus aureus (S. aureus) producer of the Panton-Valentine Leukocidine (PVL+) are becoming a new issue in public health. Those bacteria are accountable for serious cutaneous infection with a necrotic evolution, necrotizing pneumonia and severe osteoarticular infection. These last infections can be life-threatening and are at high risk of complications. Therefore, a multidisciplinary approach is necessary, in addition with an aggressive chirurgical treatment. We are here reporting 3 cases of osteoarticular infections by S. aureus PVL+ sensitive to methicilline, which illustrate the difficulties encountered in the management and treatment, as well as the potential for serious orthopedics complications.
