Determinations of serum calcium (Ca), phosphorus (P), calcitonin (CT), and parathyroid hormone (PTH) were carried out in 36 full-term newborn infants with fracture of the clavicle (CF) and in 46 normal neonates (N). At the 6th hour of life the CF neonates demonstrated lower serum Ca and higher serum CT in comparison with normal infants. In the hours following, no significant differences between the two groups for the Ca levels were found, whereas serum CT remained significantly higher in the CF newborns at the 24th, 48th, and 72nd hour of life. Significant differences between normal and CF infants in the PTH serum levels were detected only at the 48th hour, when PTH was lower in the CF newborns. The results of this investigation indicate that the fracture of the clavicle is a significant and peculiar factor in stimulating CT secretion. Serum Ca level appeared to be controlled by CT rather than auto-regulating the secretion of the hormone.
对36例患有锁骨骨折（CF）的足月儿和46例正常新生儿（N）进行了血清钙（Ca）、磷（P）、降钙素（CT）和甲状旁腺激素（PTH）测定。与正常婴儿相比，CF新生儿在出生后第6小时血清Ca水平较低，血清CT水平较高。在随后的几个小时里，两组之间的Ca水平没有显著差异，而在出生后第24、48和72小时，CF新生儿的血清CT水平仍显著较高。仅在出生后第48小时检测到正常婴儿和CF婴儿的PTH血清水平存在显著差异，此时CF新生儿的PTH较低。本研究结果表明，锁骨骨折是刺激CT分泌的一个重要且特殊的因素。血清Ca水平似乎受CT控制，而非激素分泌的自我调节。
