shortened fetal humerus

Shortened fetal humerus is a morphological description and is usually defined when the humeral length falls below the 5 percentile or less than 0.9 as predicted by the biparietal diameter (BPD). It can occur in isolation or in association with a number of other anomalies.

The humeral length is not a typical fetal biometric parameter.
