Abstract:

Objective：To investigate the clinical value of prenatal ultrasound diagnosis of fetal skeletal malformations in the limbs.
Methods：Retrospective analysis of ultrasonographic features in 32 cases of fetal skeletal malformations of the limbs was conducted，the results were compared to the X-ray examination results and autopsy results postpartum or after induced abortion. Results：Prenatal ultrasound diagnosis of 32 cases of fetal limb skeletal system malformations matched the results of X-ray examination and the results from autopsy postpartum or after induced abortion. Among the 32 cases, there were 6 cases of dwarf lethal deformity, 4 cases of short limbs deformity, 2 cases of limb flexion deformity, 1 case of bilateral absence of upper limb deformity of radius and ulna, 1 case of absence of one side of the upper radial deformity, 2 cases of absence of upper limb deformity, 3 cases of absence of lower limb deformity, 2 cases of hand-foot multi-finger（toe）deformity, 1 case of foot missing（toe）malformation, 9 cases of clubfoot deformity,
and 1 case of sequence of human fish levy. Conclusion: Being accurate, safe, non-invasive, non-radiative and repeatable, prenatal ultrasound diagnosis of fetal limb skeletal system was an effective way.

Key words: fetal limb skeletal system malformations, ultrasonography, prenatal diagnosis
