ABSTRACT
Meticulous details conceming a case of recurrent osteomyelitis were published by Rosner.35 A patient with osteomyelitis of the femur responded well when treated with methicillin followed by oxacillin. Twenty-six months after his operation, the patient again experienced pain in the area of previous infection and exhibited a low-grade fever. Antibiotics were withheld until after surgical exploration. A sinus from the surface of the old lesion contained thickened exudate. Cultures of this material were positive only on hypertonic medium, yielding growth which reverted to Staphy lococcus aureus of the same phage type originally infecting the patient, type 80-8 1 . Direct smears obtained at his second hospitalization showed that exudate from the draining sinus and abscess contained occasional large, poorly staining, pleomorphic bodies , but no recognizable staphylococci.
