What is trabecular system of femur?
What is trabecular system of femur?
Structure. Trabecular bone, also called cancellous bone, is porous bone composed of trabeculated bone tissue. It can be found at the ends of long bones like the femur, where the bone is actually not solid but is full of holes connected by thin rods and plates of bone tissue.
What are the two major trabecular system in the femur?
The medial trabecular system forms in response to the joint re action force on the femoral head; the epiphyseal plates are perpendi- cular to the medial trabecular system. The lateral trabecular system resists the compressive force on the femoral head resulting from contraction of the ab- ductor muscles.
Where is trabecular bone typically found?
ends of long bones
Trabecular or cancellous bone is found predominantly at the ends of long bones and inner parts of flat bones and is composed of interconnecting plates and bars within which lies the bone marrow.
What is trabecular bone fracture?
The porous space between the trabeculae is filled with bone marrow, providing the bone with a rich vascular environment. In trabecular bone fractures the trabeculae collapse, break, or are crushed, reducing the strength of the structure (Hayes and Carter, 1976).
What are trabeculae and their function?
What is the function of trabecular bone? Trabecular bone is found inside spongy or cancellous bone. The trabeculae act like a network of supporting beams to provide strength and support to the bones.
What are the major features of the proximal portion of the femur?
Answer and Explanation: Th major features of the proximal femur are the head, greater trochanter, and lesser trochanter.
Where is the proximal femur?
Proximal femur includes the femoral head, neck and the region 5-cm distal to the lesser trochanter. There is a 125°–130° inclination angle between the head and neck and the femoral body. Further, there is a 15° anteversion angle between the plane passing through the condyles of the femoral head and the femur neck.
What is found throughout trabecular bone?
Cancellous bone also contains a lot of red bone marrow that fills up the spaces between trabeculae. This bone marrow is really important because it is where all the blood cells in your body are made.
How is trabecular bone formed?
The inter-trabecular healing process after trauma starts with a hematoma, which is followed by inflammation (Kon et al. 2001). Inflammation is followed by mesenchymal cell condensations forming osteoid, which becomes woven bone (Figure 2). This is then remodeled into lamellar bone (Charnley and Baker 1952, Chen et al.
