At 32 weeks of pregnancy, the average biparietal diameter is 8.17 ± 0.65, and the average femur length is 6.43 ± 0.49. According to the provided data (biparietal diameter: 79mm, femur: 49mm), the baby’s legs appear shorter than the normal average. In this case, it is not ruled out that there may be a deformation.
