This study created a new fetal clavicle length (CL) nomogram using high-resolution ultrasound. The new nomogram, based on 623 fetuses, differs significantly from older data and offers improved accuracy for gestational age assessment.

Area of Science:

  • Obstetrics and Gynecology
  • Fetal Medicine
  • Diagnostic Ultrasound

Background:

  • Accurate fetal biometry is crucial for monitoring pregnancy progression and detecting potential abnormalities.
  • Existing nomograms for fetal clavicle length (CL) may not reflect current sonographic capabilities or population data.

Purpose of the Study:

  • To develop an updated nomogram for fetal clavicle length (CL) across a wide range of gestational ages (14-42 weeks).
  • To compare new CL data with historical nomograms and assess the accuracy of common rules of thumb for gestational dating.

Main Methods:

  • A cross-sectional study involving 623 singleton, non-anomalous fetuses with well-established gestational dating.
  • Sonographic measurements included biparietal diameter, head circumference, abdominal circumference, femur length, humerus length, and sonographically estimated fetal weight.

  • Fetal clavicle length (CL) was measured, and the 5th, 50th, and 95th centiles were determined using least squares regression.

    • Main Results:

    • Fetal clavicle length (CL) was successfully measured in 620 out of 623 fetuses.
    • A strong correlation was observed between CL and other standard fetal biometric parameters (BPD, HC, AC, HL, FL, SEFW).
    • The newly generated nomogram showed significantly larger CL measurements compared to a 1985 nomogram for most gestational ages.

    Conclusions:

    • A new, comprehensive nomogram for fetal clavicle length (CL) is proposed, reflecting advancements in ultrasound technology.
    • The updated nomogram should supersede previous data due to its larger sample size and modern methodology.
    • The '1 mm = 1 week' rule of thumb for gestational dating based on CL is deemed unreliable and potentially erroneous.
