We tested the best anatomic site, reliability, and reproducibility of single-photon absorptiometric bone density measurements in premature and term newborns. Humerus and radius measurements were compared using a commercially available densitometer. The humerus was a more reliable site of measurement, particularly in the very-low-birth-weight infant. Normal ranges of humerus bone mineral content (BMC) were defined for infants of 24 to 42 weeks' gestational age at birth. Humerus BMC correlated with gestational age and birth weight of patients. We conclude that bone densitometer measurements can be successfully performed, even in very-low-birth-weight infants, when the humerus is used as the measurements site. We define normal humerus BMC values for use in diagnosis and evaluation of efficacy of treatment in infants who are at higher risk for osteopenia of prematurity.
我们测试了单光子吸收法测量早产和足月新生儿骨密度时的最佳解剖部位、可靠性及可重复性。使用市售密度计比较了肱骨和桡骨的测量结果。肱骨是更可靠的测量部位，尤其是在极低出生体重儿中。为出生时孕龄24至42周的婴儿定义了肱骨骨矿物质含量（BMC）的正常范围。肱骨BMC与患者的孕龄和出生体重相关。我们得出结论，当将肱骨作为测量部位时，即使是极低出生体重儿也能成功进行骨密度计测量。我们定义了正常肱骨BMC值，用于诊断和评估早产性骨质减少高危婴儿的治疗效果。
