On its proximal finish, the leg bone forms a swish, spherical method referred to as the top of the leg bone. the top of the leg bone forms the ball-and-socket articulatio coxae with the cupulate cotyloid cavity of the coxal (hip) bone.
The rounded form of the top permits the leg bone to maneuver in nearly any direction at the hip, as well as motion still as rotation around its axis. simply distal from the top, the leg bone narrows significantly to create the neck of the leg bone. The neck of the leg bone extends laterally and distally from the top to produce further area for the leg to maneuver at the articulatio coxae, however, the thinness of the neck provides a section that’s liable to fractures.
What is thigh bone?
The spheroid joint may be a massive ball and socket diarthrosis between the top of the leg bone and also the cotyloid cavity of the pelvis. it’s structured in such some way that allows movement of all told axes, whereas bearing each our summer and winter body mass and providing stability for the body throughout the movement.
The spheroid joint is strengthened by a capsule and powerful ligaments; the annulate ligament of the hip, thwartwise concave, iliofemoral, pubofemoral, and ischiofemoral ligaments.
The leg bone is that the bone of the proximal part of the limb, or thigh. the pinnacle of the leg bone could be a subfigure surface that matches into the cotyloid cavity of the innominate. the pinnacle is supported by the neck, which comes obliquely from the proximal finish of the leg bone. Lateral to the pinnacle is that the chapped, proximally protrusive larger appendage, that serves for attachments of the hip muscle system. The deep depression posteriorly between the appendage and head is that the trochanteric fossa.
On the posterior surface of the shaft, simply distal to the pinnacle, is that the lesser appendage. The intertrochanteric line connects the 2 trochanters, however is very outlined on the posterior fringe of the larger appendage. the foremost distinguished muscular insertion website on the os longum is that the linea aspera, the chapped ridge that extends diagonally on the posterior surface of the leg bone.
Anatomy of Femur
The leg bone is that the massive bone within the higher part of your leg. completely different types of trauma will injury this bone, inflicting it to fracture into a pair of or additional items. This may happen to the part of the leg bone close to your knee, close to the center of the leg bone, or within the part of the leg bone that forms part of your coxa. Inbound sorts of leg bone fractures, your leg bone has broken, however, its items still line up properly.
If you fracture your leg bone, you always would like ORIF to bring your bones into place and facilitate their healing. throughout associate degree open reduction, orthopedical surgeons reposition your bone items throughout surgery, so they’re back in their correct alignment.
At the tip of the neck, the leg bone turns regarding forty-five degrees and continues distally and slightly medially toward the knee because of the body of the leg bone. At the highest of the body of the leg bone on the lateral and posterior facet could be a massive, rough bony projection referred to as the bigger appendage. simply medial and distal to the bigger appendage could be a smaller projection referred to as the lesser appendage. The bigger and lesser trochanters function a muscle attachment sites for the tendons of the many powerful muscles of the hip and groin like the iliopsoas cluster, glute, and skeletal muscle longus.
On its distal finish, the leg bone forms the hinge joint with the shinbone of the lower leg. The distal finish of the body of the leg bone widens considerably higher than the knee to create the rounded, swish medial and lateral condyles. The medial and lateral condyles of the leg bone meet with the medial and lateral condyles of the shinbone to create the articulary surfaces of the hinge joint. Between the condyles could be a depression referred to as the intercondylar fossa that gives area for the anterior symmetrical ligament (ACL) and posterior symmetrical ligament (PCL), that stabilize the knee on its anterior/posterior axis.
Femur in Human Body
Although the condyle is smaller than the condyle, it’s additional without delay palpable. It conjointly accounts for the characteristic inward bulging at the knees. it’s related to a little conic protuberance called the skeletal muscle tubercle, which provides a degree of attachment for the massive skeletal muscle Magnus (powerful medial thigh muscle that moves the thigh medially).
The medial process is set below and anterior to the skeletal muscle tubercle. It conjointly provides attachment for the connective tissue of skeletal muscle Magnus muscle yet because of the leg bone collateral ligament (supporting structure connecting the shin to the femur). The tendons of musculus sartorius and gracilis muscles conjointly skip (but haven’t any attachments) to the condyle of the thighbone.
Of the 2 condyles, the condyle is larger and additional outstanding than the condyle. Like its counterpart, it’s conjointly related to an epicondyle, that functions as a degree of attachment for the lateral collateral ligament. The condyle conjointly features a shallow groove below the epicondyle through that the ginglymus connective tissue travels.
