BACKGROUND: The study of bone mineralization in the neonatal period and of bone disease is receiving increasing interest. Osteosonography is a new method for measuring bone mineralization without exposing the patient to radiation. OBJECTIVE: To determine the speed of ultrasound in healthy newborns, the possible variations in preterm infants, and their relationship with gestational age and anthropometry. METHODS: One-hundred newborns (53 term infants [26 males, 27 females] and 47 preterm infants [27 males and 20 females]) were studied. The variables measured were gestational age, length, weight, circumferences (head and thoracic) and amplitude-dependent speed of sound (Ad-SOS). A prior study was carried out to select the area of measurement with ultrasound between both femora and humeri. RESULTS: No significant differences in Ad-SOS were found between the right and left femora or humeri, but there were significant differences between femora and humeri (p 0.001). The mean Ad-SOS in the population was 1706.6 36.3 m/s. Ad-SOS was 1726 26.2 m/s in term infants and 1679 36.7 m/s in preterm infants; this difference was statistically significant. Correlations were also found between Ad-SOS and gestational age and anthropometric variables. CONCLUSIONS: Ad-SOS is an effective method for bone mineralization screening in newborns and for detecting postnatal changes.
