Shortened fetal humerus

Last revised by Dr Jeremy Jones on 20 Sep 2021

A shortened fetal humerus is a morphological description and is usually defined when the humeral length falls below the 5th 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.
