    Fetal weight was estimated sonographically within 3 days of delivery in 103 cases. A stepwise regression analysis was performed to evaluate fetal sex, biparietal diameter, head circumference, abdominal circumference, and femur length as factors in estimation of fetal weight. A new formula for calculating fetal weight was derived. Fetal sex did not affect the results obtained. Incorporation of femur length improved the reliability of the weight estimate. Because of intrapopulation and interpopulation differences, institutions using obstetric ultrasound examination techniques should establish their own formulas for estimating fetal weight.

    The femur is the body's longest and strongest bone spanning the thigh region. Its head articulates with the acetabulum of the hip bone to form the hip joint. A minor indentation on the medial side of the femoral head, called the fovea capitis, serves as the site of attachment for the ligament of the head of the femur. This weak ligament spans the femur and acetabulum and supports the hip joint. The narrowed region below the head is the neck of the femur. The inclination angle between the neck...
