Nov 13, 2020 · The shaft of the femur descends in a slight medial direction. This brings the knees closer to the body’s centre of gravity, increasing stability. A cross section of the shaft in the middle is circular but flattened posteriorly at the proximal and distal aspects.

Sep 11, 2023 · Proximally, the femur articulates with the pelvic bone. Distally, it interacts with the patella and the proximal aspect of the tibia. The femur begins to develop between the 5th to 6th gestational week by way of endochondral ossification (where a bone is formed using a cartilage-based foundation).

Nov 8, 2021 · The femur is a long bone with two ends: proximal and distal. The end, which lies on the side of the hip, is called the proximal femur, and another on the side of the knee is referred to as the distal femur. The region between these two ends is called the shaft.

Even though it’s one long bone, your femur is made up of several parts. These include: The upper (proximal) end of your femur connects to your hip joint. The proximal end (aspect) contains the: Head. Neck. Greater trochanter. Lesser trochanter. Intertrochanteric line and crest.

May 15, 2024 · On the femur’s upper end (proximal aspect) are the femoral head and neck. The hip joint connects the head of the femur and the pelvis like a ball and socket.

3 days ago · Location. The femur is located in the thigh region, extending from the hip to the knee. [4] Proximally, it articulates with the hip bone at the acetabulum, ... Proximal End Head of the Femur. Shape and Position: Spherical in shape and forms the proximal-most part of the femur.

Aug 11, 2024 · The only bone in the upper leg, the femur is divided into three parts: proximal, shaft, and distal. Proximal end: This part of the femur includes the femoral head, the ball part of the ball-and-socket hip joint, the neck, and the greater trochanter.

The femoral head of the proximal femur articulates with the acetabulum of the pelvis in which the femoral head acts at the ball and the acetabulum as the socket. Allows for movement at the hip in three planes : flexion and extension in the sagittal plane, abduction and adduction in the frontal plane, and internal and external rotation in the ...

Nov 17, 2023 · At the proximal end, the pyramid-shaped neck attaches the spherical head at the apex and the cylindrical shaft at the base. There are also two prominent bony protrusions, the greater and lesser trochanter, that attach to muscles that move the hip and knee.

Jun 9, 2024 · Overview of Femur Anatomy. The femur, or thigh bone, is the main bone in your thigh. It connects your hip to your knee and is your body’s largest and strongest bone. In animals with four legs, it is the upper bone in the back leg. The femur anatomy has several parts: the shaft, head, neck, and more.
