Femur Length

Specialty:

Objective:

ICD-10:

Description:

Femur length correlates with fetal length and in turn fetal age. The femur length measured by ultrasound is the linear distance between the proximal and distal diaphyseal plates, which can be measured fairly accurately. Since the epiphyseal portions are cartilagenous, they cannot be as readily visualized. It is can be used at 12 weeks of gestation and later (second and third trimesters).
