The posterior surface of the neck of the femur is directed posterosuperiorly. It consists of a head and neck, and two bony processes the greater and lesser trochanters.

On examination, the affected limb is externally rotated when the hip is flexed and there may be limb length discrepancy. The tibia and fibula are the two long bones in the leg that articulate with the femur to form the knee joint. Although it does not directly articulate, some argue that the patella could be classified as a bone that articulates with the tibia because the two are loosely connected by the patellar tendon. [1][2] The leg is the region of the lower limb between the knee and the foot. D. manubrium and xiphoid process The medial supracondylar line continues to the adductor tubercle (on the medial condyle) and the lateral supracondylar line ends at the lateral condyle. The line then continues as the spiral line of the femur at the inferior aspect of the intertrochanteric line and continues into the medial lip of the linea aspera on the femoral shaft. B. lined by a secretory membrane B. dorsal and costal On the other hand, the anterior surface is flattened, located within the joint capsule, and meets the proximal end of the femoral shaft at the intertrochanteric line. The head of the femur will articulate with the acetabulum of the hip bone. The patella is the kneecap and articulates with the distal femur. How long does it take to recover from a broken femur? The intertrochanteric line starts anteriorly on a tubercle on the apex of the greater trochanter, near the intersection between the shaft and neck of the femur.

Anteriorly, the shaft is smooth and devoid of distinguishing features. What are the three bones that articulate with femur? The patella is the kneecap and articulates with the femur. Pubic body - located medially, it articulates with the opposite pubic body at the pubic symphysis.Its superior aspect is marked by a rounded thickening (the pubic crest), which extends laterally as the pubic tubercle. The femur, thigh bone is present in between the hip joint and the knee joint. D. 9 B. medial end of clavicle These are the femur, patella, tibia, fibula, tarsal bones, metatarsal bones, and phalanges (see Figure 8.2 ). Patellofemoral articulation, along with the attached quadriceps and patellar tendons, forms the extensor mechanism of the knee. The lateral condyle also has a shallow groove below the lateral epicondyle through which the popliteal tendon travels. We use cookies to ensure that we give you the best experience on our website.

However, there are other disorders that may arise from non-traumatic events (e.g. Descriptive ethics: What do people think is right? It is associated with a small conical protuberance known as the adductor tubercle, which provides a point of attachment for the large adductor magnus (powerful medial thigh musclethat moves the thigh medially). What is the tarsal bone that articulates with the tibia? Blends with the tendon of biceps femoris but does not integrate with the joint capsule. The quadriceps femoris is a large muscle group of the anterior thigh consisting of the rectus femoris, vastus lateralis, vastus intermedius, and vastus medialis, that acts as the primary extensor muscle of the knee. Its rounded head articulates with the acetabulum of the hip bone to form the hip joint. Alternatively, a fall from any height in an elderly patient may also result in a neck of femur fracture. Runs from the lateral femoral condyle to the head of the fibula. Articulating with Starting at the acetabullum(hip/pelvis), the femur is the major Name the three bones that articulate with the femur.
