What is the anatomy of the femur?
The femur is your thigh bone. It’s the longest, strongest bone in your body. It’s a critical part of your ability to stand and move. Your femur also supports lots of important muscles, tendons, ligaments and parts of your circulatory system.
What are the 3 parts of the femur?
The femur acts as the site of origin and attachment of many muscles and ligaments, and can be divided into three parts; proximal, shaft and distal. Proximal Femur consists of: femoral head – pointed in a medial, superior, and slightly anterior direction.
What is unique about the femur?
The femur is the longest bone in the body. In fact, it’s the longest of all the long bones (which also include the tibia, fibula, metatarsals, and phalanges in the lower limb and the humerus, radius, ulna, metacarpals, and phalanges in the upper limb).
How long is a normal femur?
The average adult femur is anywhere from about 16 inches to 19 inches in length, depending on the height of the individual.
Where are the femur?
Below the lesser trochanter is the gluteal tuberosity, which is where the gluteus maximus is attached. The main shaft of the femur is known as the body. The distal end of the femur (the end furthest from the heart) is where it connects with the patella (knee cap) and the bones of the lower leg (the tibia and fibula).
What is the head of the femur called?
The femoral head is the most proximal portion of the femur and is supported by the femoral neck. It articulates with the acetabulum of the pelvis. The femoral head is nearly spherical (two-thirds) but has a medial depression known as the fovea capitis femoris that serves as an attachment point for the ligamentum teres.
How thick is the femur?
Much of the femoral cortex is less than 3mm thick, appearing so blurred in clinical CT that its actual density is not apparent in the data, and neither thresholding nor full-width half-maximum techniques are capable of determining its width.
What is the femur length chart?
| A | I | |
|---|---|---|
| 1 | Gestational Age (Weeks) | Femur Length (mm) by Percentile |
| 2 | 95 | |
| 3 | 14 | 16 |
| 4 | 15 | 19 |
Is the femur a long bone?
The thigh bone (femur) is a long bone. A long bone has a shaft and two ends. Some bones in the fingers are classified as long bones, even though they are short in length. This is due to the shape of the bones, not their size.
What is a normal projection on the surface of a bone?
opening in a bone through which blood vessels, nerves and ligaments pass. process. normal projection on the surface of a bone that serves as an attachment for muscles and tendons. suture. immovable joint.
What is the normal femur length at 38 weeks?
Calculating estimated fetal weight (EFW)
| Gestational Age (Weeks) | BPD | Femur Length |
|---|---|---|
| 36 weeks | 90 | 70 |
| 37 weeks | 92 | 72 |
| 38 weeks | 94 | 73 |
| 39 weeks | 95 | 75 |
What is the femur length of baby Boy?
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.
What is the structure and function of the femur?
The femur is the largest and strongest bone in the human body. 1It is commonly known as the thigh bone (femur is Latin for thigh) and reaches from the hip to the knee. This article discusses the function and structure of the thigh bone, as well as information about conditions that can affect it.
Femur anatomy is so unique that it makes the bone suitable for supporting the numerous muscular and ligamentous attachments within this region, in addition to maximally extending the limb during ambulation. Proximally, the femur articulates with the pelvic bone. Distally, it interacts with the patella and the proximal aspect of the tibia.
Does the distal end of the femur have a high blood supply?
The distal end of the femur has a rich blood supply arising from the popliteal vessels and the deep perforators. These vessels are not as vulnerable as those at the neck of the femur. Therefore the risk of avascular necrosis is negligible in this area.
What is the blood supply to the proximal femur?
Blood supply The blood supply of the proximal femur is of particular medical interest because of its susceptibility to damage. The so-called trochanteric anastomosis includes the medial and lateral circumflex femoral arteries (branches of the femoral artery) along with branches of the superior and inferior gluteal arteries.
What is the shape of the femoral shaft?
The femoral shaft is a cylindrical structure with significant variability from one individual to another. The shaft is relatively wide at the proximal end but becomes progressively narrow toward the middle. It is bowed anteriorly, which contributes to the weight bearing capacity of the bone.
