What is fetal femur length?
Fetal femur length (FL) is one of the basic biometric parameters used to assess fetal size. Femur length together with biparietal diameter, head circumference, and abdominal circumference are computed to produce an estimate of fetal weight.
How is femur length measured?
Femur Length Measurement Measured from the blunt end of the bone to the shaft, the femur length is generally measured in millimeters. A short femur length finding on ultrasound may indicate the need for further testing to rule out certain conditions.
What is the normal fl at 28 weeks?
Calculating estimated fetal weight (EFW)
| Gestational Age (Weeks) | BPD | Femur Length |
|---|---|---|
| 27 weeks | 69 | 52 |
| 28 weeks | 72 | 54 |
| 29 weeks | 74 | 56 |
| 30 weeks | 77 | 59 |
What is the normal fl at 22 weeks?
Track your pregnancy
| Weeks | BPD (mm) | FL (mm) |

| 20.5 | 48.1 | 34.1 |
| 21 | 49.7 | 35.6 |
| 21.5 | 51.4 | 37.0 |

What is the average length of a femur?
The average adult femur is anywhere from about 16 inches to 19 inches in length, depending on the height of the individual.
How tall is the femur?
The mean of femur length and height was 41.18cm ± 0.03 and 164.47cm ± 0.65 respectively for the sample population in the male, the female length and height was 41.79cm ± 0.16 and 167.50cm ± 0.78 respectively, while in the female population the femur length was 40.82cm ± 0.26 and the height in 161.90cm ± 0.95.
What is FL in 32 weeks of pregnancy?
Femur length (FL) Measures the longest bone in the body and reflects the longitudinal growth of the fetus. Its usefulness is similar to the BPD. It increases from about 1.5 cm at 14 weeks to about 7.8 cm at term.
How long is a femur for a 6ft man?
tall person, the femur might be 19.5 in. long.
How long is femur bone in cm?
The whole length of the femur is about 42 and 45 cm for female and male human subjects, respectively [10, 16] .
What is the maximum length of the femur?
Right femur: The maximum length of right male femur varied from 395mm to 506mm (Mean: 451.81 & S.D.: 23.94) and of right female femur varied from 376mm to 473mm (Mean: 417.48 & S.D.: 19.74). Mean value of maximum length was higher in male as compared to female.
Can FL determine gender?
These prenatal sex-related differences are established by as early as 16 weeks of gestation and tend to increase with advancing gestational age. In the case of discrepancy finding between head (HC, BPD) and femur lenght (FL) measurements the fetal gender should be taken into account.

How is femoral diaphysis length measured?
The femoral diaphysis length (FL) is a linear structure and is measured along its ossified shaft (diaphysis) from one end to the other, disregarding the epiphyseal cartilages ( Fig. 12-9 ). The normal diaphysis has a straight lateral and curved medial border.
Is menstrual age related to femur and humerus diaphysis length?
The relationship between menstrual age and both femur and humerus diaphysis length was determined, and percentile values for each menstrual week were provided.
How is the length of the femur measured during pregnancy?
Femur length is used in conjunction with the head measurement to establish gestational age. The femoral diaphysis length (FL) is a linear structure and is measured along its ossified shaft (diaphysis) from one end to the other, disregarding the epiphyseal cartilages ( Fig. 12-9 ).
How stable are diaphyseal femur fractures?
In most diaphyseal femur fractures, this translates into a both locations. Pattern, location, and degree of comminution contribute to overall fracture stability. For example, short oblique fracture Winquist-Hansen type II ( Fig. 20.1) ( 18 ). fractures are not stable under axial loading.
