Superior (Proximal) End Its proximal end is characterized by Head Neck, Two large projections (the greater and lesser trochanters) on the upper part of the shaft. The knee joins the thigh bone (femur) to the shin bone (tibia). The femur, the longest and strongest bone in the skeleton, is almost perfectly cylindrical in the greater part of its extent.In the erect posture it is not vertical, being separated above from its fellow by a considerable interval, which corresponds to the breadth of the pelvis, but inclining gradually downward and medialward, so as to approach its fellow toward its lower part, for the purpose of bringing the … The femur is joined to several muscles via attachment sites. Distally, it cooperates with the patella and the proximal prospect of the tibia. The cup and the stem may be pressed into place or fixed with bone "cement". Femur (2) Tibia (2) Fibula (2) Patella (2) Tarsals (14) Metatarsals (10) Phalanges (28) Total number of bones=60. The femur figure is so exclusive that it makes the bone satisfactory for bolstering the numerous muscular and ligamentous connections within this zone, in addition to maximally stretching the limb during ambulation. The femur belongs to long bones, and it has three parts: a proximal extremity, a shaft in the middle of the bone, and a distal extremity. There are three main parts to the femur: The other two are the semimembranosus muscle…, The main adductors of the hip are the adductor magnus muscle, the adductor longus muscle, and the adductor brevis muscle. (©2003 www.clipart.com) The Big Picture. You may have needed surgery to repair the bone. Tibia and Fibula Bones Quiz – Anterior Markings. Our website services, content, and products are for informational purposes only. It is both the longest and the strongest bone in the human body, extending from the hip to the knee. The femoral shaft is a cylindrical structure with significant variability from one individual to another. The Femur Is Considered The Longest, Largest, And Strongest Bone In The Human Body. Start Quiz. It Is Difficult For Anyone To Walk With A Broken Femur. Death Can Occur Following A Femur Fracture From Complications Such As Blood Clots, Pneumonia, Or Infection. The shaft of the femur is gradually convex anteriorly with maximum convexity in the middle third where the shaft is narrowest. It occurs when the top part of the femur (leg bone) is broken, just below the ball and socket joint. Orthopedic surgeons perform this operation to realign it and restore a more normal appearance. In this surgery, your surgeon will make a cut to the skin to align your broken bone. It is the location of the connection for the iliofemoral ligament (the strongest ligament of the hip joint). Femur bone anatomy. Vastus lateralis is the lateral-most head. These types of fractures are called intra-articular. on the sides of each condyle. These exercises can be utilized to divert sensations of pain and regulate proper circulation of blood to different parts of the body, including the affected parts around the femur. Two large prominences, or condyles, on either side of the lower end of the femur form the upper half of the knee joint, which is completed below by the tibia (shin) and patella (kneecap). 3. The proximal prospect of the femur links with the acetabulum of the pelvis to form the hip joint. It subsists of a head and neck, and two bony processes – the greater and lesser trochanters. Figure 5.1The many parts of a typical long bone. Broken femur. A big long bone. A leg is made up of three bones. When the femur and hip bone connect, they form one of the most important joints in the Human body: the hip joint. The ventral and dorsal aspect of the distal part of the right thigh bone. The end of the bone is covered with a smooth surface called articular cartilage. The distribution of the weight of the organism is important in order to prevent trauma to supporting structures. Beside above, how does the femur articulate with the tibia? Inability To Move Your Hip Or Knee On The Affected Side. The linea aspera then diverges toward the distal third of the femur where the medial and lateral lips become continuous with their respective ipsilateral supracondylar line (medial and lateral supracondylar lines). 6. Firstly, the neck of the femur is angled superomedially in order to fit into the acetabulum. There are also two bony ridges linking the two trochanters; the intertrochanteric line anteriorly and the trochanteric crest posteriorly. It serves as the attachment site for several muscles of the hip and leg, allowing it to withhold pressure from multiple angles. The caudal aspect of the surface forms part of the floor of the popliteal fossa. Psoas major muscle Insert into the lesser trochanter. Legs . of the lower limb, between the hip and knee joints. It is both the longest and the strongest bone in the human body, extending from the hip to the knee. intercondylar fossa. Humans are bipedal organisms–meaning that they are able to walk on two legs. The head of the femur articulates with the acetabulum in the pelvic bone forming the hip joint, while the distal part of the femur articulates with the tibia and kneecap forming the knee joint. The distal end of the femur is one of the four boney parts of the knee. While several ossification places (points of bone development) emerge went through intrauterine life, the bone continues to advance through childhood and early boyhood. The hip bones also form the socket portion of the hip joint. Enter your email address to subscribe to this blog and receive notifications of new posts by email. It is not dissimilar in architecture overall to the humerus and at its distal joint also to the finger and toe bones. It originates at the greater trochanter and the linea aspera of the femur. linea aspera. The femur is a very large, strong bone that is difficult to break. The Femur Thigh bone Dr M Idris Siddiqui 2. The others are tibia, patella, and indirectly (by being a ligament handle) the fibula. Related Articles. little bone poking out under the head. Digitized model was first modeled as Shell and cloud points, i.e. The femur 1. Retake Quiz. This article will analyze the gross anatomy of the femur. It is bordered medially and laterally by the corresponding supracondylar lines, and inferiorly by the superior border of the fibrous capsule of the knee. The example shown here is a femur. To treat a child’s broken femur, the pieces of bone are realigned and held in place for healing. The shaft then undergoes marked re-expansion towards the distal end. The long, straight part of the femur is called the femoral shaft. This type of broken leg almost always requires surgery to heal.
