Thigh bone (femur)

Synonyms

Femoral neck, hip joint, knee joint, femoral condyle, trochlea, head femoris, femoral head, femoral head

English: femur, thigh bone

anatomy

The femur (Femur) is the largest bone in the human body. Like the tibia and fibula, it is a tubular bone. That means it consists of a hard coat (Compakta) and a soft cavity filled with blood cells (Cancellous bone).

With his femoral head (femoral head = Head femoris) it forms the hip joint with the hip socket of the pelvis. This is a so-called ball joint.

The femoral head is critically supplied with blood.The blood flow takes place in a kind of one-way street from the femoral neck back to the femoral head. Circulatory disorders in this area are therefore more common.

The femoral head is directly connected to the femoral neck. The Femoral neck stands in an adult at approx. 127 ° to the thigh shaft (Femoral shaft).

At the tip of the thigh shaft you can find the on the outside Greater trochanter (large rolling mound) and on the inside the Lesser trochanter (small rolling mound). Both are starting points (Apophyses) for big Muscle groups (Hip flexors and splitters)

The thighbone ends at the knee joint with its two thigh rollers (medial and lateral femoral condyle). These two thigh rolls form with the shin (Tibia) the Knee joint.

function

The head of the femur and the socket of the pelvis form the hip joint.

With the condyles of the thigh bone, it forms the knee joint with the shin bone.

As the only bone in the thigh, it transfers all of the force from the body (pelvis) to the lower leg (shin / tibia).

Thigh bone diseases

Gonarthrosis and coxarthrosis

The most common disease of the thigh bone is osteoarthritis of the knee joint (Osteoarthritis of the knee). This is followed by osteoarthritis of the hip joint (Coxarthrosis).

Femoral neck fracture

With increasing age and decreasing bone quality, the fracture of the femoral neck increases (Femoral neck fracture) to. This leads to a break between the femoral neck and femoral head. In most cases, a femoral neck fracture has to be treated surgically.

Artificial Knee Joint / Artificial Hip Joint

A femoral shaft fracture is rare and more likely to occur when great force is used, such as in a traffic accident or a artificial knee joint or artificial hip joint in front.

Fractures above the joint rollers, a so-called one supracondylar femoral fracture also occurs in old age and almost always has to be treated surgically.

Appointment with ?

I would be happy to advise you!

Who am I?
My name is dr. Nicolas Gumpert. I am a specialist in orthopedics and the founder of and work as an orthopedist at Lumedis.
Various television programs and print media report regularly about my work. On HR television you can see me live every 6 weeks on "Hallo Hessen".
But now enough is indicated ;-)

In order to be able to treat successfully in orthopedics, a thorough examination, diagnosis and a medical history are required.
In our very economic world in particular, there is not enough time to thoroughly grasp the complex diseases of orthopedics and thus initiate targeted treatment.
I don't want to join the ranks of "quick knife pullers".
The aim of all treatment is treatment without surgery.

Which therapy achieves the best results in the long term can only be determined after looking at all of the information (Examination, X-ray, ultrasound, MRI, etc.) be assessed.

You will find me:

• Lumedis - orthopedic surgeons
  Kaiserstrasse 14
  60311 Frankfurt am Main

You can make an appointment here.
Unfortunately, it is currently only possible to make an appointment with private health insurers. I hope for your understanding!
