Spalding's sign
Spalding's sign is a sign used in obstetrics.[1] It is named for Alfred Baker Spalding.[2][3]
It is an indicator of
fetal death.[4] When fetal death has occurred loss of alignment and overriding of the bones of cranial vault occur due to shrinkage of cerebrum,[5] abdominal sonar examination may reveal an overriding of the fetal cranial bones.[6]
Most
estimates place the precise time of fetal death at about 4–7 days before overlapping and separation of the fetal
skull bones appear.[7]
