Hypoechogenicity of fetal long bones: a new ultrasound marker for arthrogryposis.
OBJECTIVE
To demonstrate osteopenia associated with arthrogryposis.


RESULTS
We describe 3 cases of fetal arthrogryposis seen prenatally with the sonographic feature of severe hypoechogenicity of the long bones. This manifestation of presumed osteopenia is thought to represent osteoporosis secondary with absent fetal movement.


CONCLUSIONS
We describe hypoechogenicity of the fetal bones as a new sonographic feature of arthrogryposis.
