Unlabelled:
In a biomechanical study we evaluated the stability of human femurs. In order to document the inter- and intraindividual differences in bending stability, we tested 200 bone samples, harvested from the femurs of 5 multiorgan donors. The bending tests were performed on a material testing machine (ZWICK) under standardized conditions. Our results revealed significant differences in the stability of the femurs of the 5 multiorgan donors. Furthermore, there was a significant difference in breaking strength at different levels of the same bone.
Clinical Relevance:
In studies aimed at evaluating the primary bony stability of alloimplants after different preservation or sterilization procedures, the above-mentioned results should be taken into consideration.

Bone as Supporting Connective Tissue
Bone Matrix
Bone, or osseous tissue, is a connective tissue that has a large amount of two different types of matrix material. The organic matrix is similar to the matrix material found in other connective tissues, including some amount of collagen and elastic fibers. This gives strength and flexibility to the tissue. The inorganic matrix consists of mineral salts— mostly calcium salts— that give the...
Compact Bone
Compact bone, also called cortical bone, is the denser, stronger of the two types of bone tissue. It is found under the periosteum and in the diaphyses of long bones, where it provides support and protection. The microscopic structural unit of compact bone is called an osteon, or haversian system. Each osteon is composed of concentric rings of calcified...
Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Components of the Skeletal System
Bone, or osseous tissue, is a hard connective tissue that forms an internal support structure for the human body. Bones shield vulnerable organs and soft tissue from external forces. For example, the vertebral bones protect and support the spinal cord.
