While most cases only affect one side (the left more often than the right), it is not uncommon to see bilateral pathology. In addition, the fibula is not a weight-bearing structure (the tibia is the weight-bearing bone of the lower leg). The inferior margin is more oblique in orientation and projects posteroinferiorly and laterally toward the lesser trochanter. It is mandatory to procure user consent prior to running these cookies on your website. Over time, the recurrent wear and tear result in damage to the cartilaginous covering, leading to osteoarthritis. (b) The minimum safe value of \phi would decrease. The lower limb contains 30 bones. The lateral border becomes thegluteal tuberosity,where the gluteus maximus attaches. A. loss of annulus fibrosis elasticity A. first class A. scapula The distal femur articulates with the superiortibia, which is the larger of the bones in the lower leg. All three bones that form the hip bone contribute to creating the acetabulum. It articulates proximally with the trochlea of the humerus and with the head of the radius. Not only is the distal femur the widest part of the bone, but it also interacts with both the proximal tibiaand the patella. This information is intended for medical education, and does not create any doctor-patient relationship, and should not be used as a substitute for professional diagnosis and treatment. However, extreme variation of the angle of inclination could change this relationship and increase the amount of stress across the neck of the femur. These vessels are not as vulnerable as those at the neck of the femur. Fig 3 Posterior surface of the right femoral shaft. Is the femur the strongest bone in the body? The patella joins with the patellar surface of the femur. The femoral condyles rest on very shallow, complementary depressions on the proximal tibial plateau known as facets. The head of the fibula forms the proximal end and articulates with the underside of the lateral condyle of the tibia. Our experts can answer your tough homework and study questions. The pelvic girdle is formed by a single hip bone. Descriptive ethics: What do people think is right? D. protrusion of the nucleus pulposus It is the site of attachment for iliopsoas (forceful contraction of which can cause an avulsion fracture of the lesser trochanter). There is a posterolateral surface which is limited anteriorly by the lateral border and posteriorly by the linea aspera. Required fields are marked *. B. symphysis Below the ankle is the foot. The tibia is the larger, weight-bearing bone located on the side of the leg, and the fibula is the thin bone of the lateral leg beside the tibia. As the name implies, an articulation is where two bone surfaces come together (articulus = "joint"). The hip bones articulate with the sacrum at the sacroiliac joint. On the other hand, if there is an overgrowth of the acetabulum such that it hits the head of the femur during movement, then it is known as a pincer deformity. B. glenoid cavity and scapular spine What are the six bones found in all tetrapod legs? It lies deep to the iliotibial tract(fibrous continuation of the tensor fasciae latae), which also inserts on the lateral femoral condyle. Ethical claims are evaluative or normative.

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. The femur articulates proximally with the acetabulum of the pelvis to form the hip joint, and distally with the tibia and patella to form the knee joint. The extracapsular fractures are also called basicervical fractures, while intracapsular fractures are transcervical and subcapital. The distal fragment is typically pulled upwards and rotated laterally. They can often occur as aspiralfracture, which causes legshortening. The pelvis features two cup-shaded depressions called the acetabulum, one on either side of the body. It consists of a head and neck, and two bony processes - the greater and lesser trochanters. It then travels inferomedially to a tubercle at the lower point of the lesser trochanter. The head of the femur bone is spherical in shape and fits into the socket of the hip bone, forming the ball and socket joint of the hip.

Neoplastic disorders associated with the femur are excluded from this discussion. 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. A NORMATIVE claim, on the other hand, is a claim that asserts that such-and-such OUGHT to be the case. Ans. It is a pronounced ridge on the posterior surface of the femur, which begins at the intersection of the shaft and neck of the femur. Which of the following constitutes the pectoral girdle? The fibula bone is a long slender bone present with the tibia in the lower part of the leg, below the knee joint. At the superior (proximal) end of the tibia, a pair of flattened condyles articulate with the rounded condyles at the distal end of the femur to form the knee joint or tibiofemoral joint.

Normative ethics involves arriving at moral standards that regulate right and wrong conduct. While the apex and anterior aspect of the lesser trochanter are course to touch, the bony projection is smooth elsewhere. B. depressor labii The femoral head forms the ball in the ball and socket joint of the hip. They also form some kinds of white blood cells. The femur articulates with the tibia. On the other hand, the intertrochanteric crest is more pronounced than the intertrochanteric line. The patella is the kneecap and articulates with the distal femur.

At the knee, a superior (proximal) tibiofibular joint is formed by the . The loss of leg length is due the bony fragments overriding, pulled by their attached muscles. The neck of the bone extends outwards and slightly downwards thus forming an elongated structure. It is associated with a crescent-shaped, rough, depression known as the trochanteric fossa, found on the medial surface of the apophysis. This problem has been solved!

School Korea University; Course Title BIO LIBS151; Uploaded By premsbycelliciah44. The thigh bone is called a femur and not only is it the strongest bone in the body, it is also the longest. Of the two condyles, the lateral condyle is larger and more prominent than the medial condyle. There are two lines that connect the greater and lesser trochanters on the anterior and posterior aspect of the proximal femur. What bones does the sphenoid bone articulate with? Runs from the lateral femoral condyle to the head of the fibula. The femur bone is the long bone in the human skeletal system which arti . This intricate combination of bones is further reinforced by numerous ligaments to enhance its stability. Both femurs naturally converge towards the knee. This groove is limited anteriorly by the patellar surface and posteriorly by the intercondylar line. C. vertebra B. slippage of the fibrocartilage dic In general, we think of the hip joint as the place where the femur of the thigh articulates with the pelvis, one bone connected to the other.

C. risorius The flat popliteal surface lies between them. In younger patients they tend to occur as a result of high energy accidents. The femur is the single bone of the thigh. The concern is that reducing the epiphysis to its original state may disrupt the delicate arterial anastomosis, leading to avascular necrosis of the femoral head. The role of these two bones is to provide stability and support to the rest of the body, and through articulations . These bones are the femur, patella, tibia, fibula, tarsal bones, metatarsal bones, and phalanges.

The femur ( os femoris) extends from the hip to the knee and is the longest and strongest bone in the body. The acetabulum is a deep, cup-shaped cavity in the hip bone, where the head of the thigh bone (femur) fits, forming the hip joint.
