title: Calcaneus osteomyelitis secondary to Guthrie test: case report.
abstract: Calcaneus osteomyelitis is a rare infection in newborns. Invasive procedures, prematurity and low birth wight are some causative factors. The clinical signs may be mild. We report a neonate with calcaneous osteomyelitis which was secondary to a Guthrie test sample. She was admitted to hospital with swelling, redness and increased temperature on her heel. Superficial tissue ultrasound showed fluid collection with heavy content was observed on the posterior of the right foot. Puncture and drainage was performed and methicillin-susceptible Staphylococcus aureus was isolated from the drainage culture. Extremity magnetic resonance imaging showed tissue defect in right foot, edema-inflammation and contrast enhancement. Intravenous sulbactam-ampicillin and oral amoxicillin and clavulanic acid were given for 6 weeks. In follow-up, clinical symptoms recovered without curettage. In conclusion; calcaneous osteomyelitis should be considered in the differential diagnosis of swelling on heel in neonates who have been applied to invasive procedures as Guthrie test sample.
