Summary
The periosteum, a bone-covering sheath, changes with age and has distinct layers and vascular systems. Radiologists should understand its varied reactions to bone insults, especially in children.
Area of Science:
- Orthopedics
- Radiology
- Cell Biology
Background:
- The periosteum is a vital fibrous sheath covering external bone surfaces, excluding articular areas.
- It comprises an outer fibrous layer and an inner proliferative layer containing osteoprogenitor cells.
- Its structure and elasticity change significantly with aging.
Purpose of the Study:
- To detail the anatomical and physiological characteristics of the periosteum.
- To elucidate the periosteum's vascular supply systems.
- To highlight the periosteum's role in bone response to various pathologies and its radiological implications.
Main Methods:
- Review of anatomical and histological literature on periosteal structure.
- Analysis of vascular systems supplying the periosteum.
- Correlation of periosteal reactions with radiological findings in different age groups and conditions.
Main Results:
- The periosteum has two layers: fibrous and proliferative, with age-related changes in elasticity.
- Four vascular systems (intrinsic, periocortical, musculoperiosteal, fascioperiosteal) supply the periosteum.
- Periosteal reactions vary based on age (more exuberant in children) and insult type (tumors, infections, trauma).
Conclusions:
- Understanding periosteal anatomy, vascularity, and age-related changes is crucial for interpreting radiological signs of bone disease.
- Radiologists must recognize the diverse periosteal responses to various insults for accurate diagnosis.
- The study aims to provide essential knowledge for radiologists regarding periosteal imaging.

The two main features of a long bone are the diaphysis and the epiphysis.
The diaphysis is the tubular shaft that runs between the proximal and distal ends of the bone. The walls of the diaphysis are composed of dense and hard compact bone made of numerous osteons — the functional unit of the compact bone. The hollow region in the diaphysis is called the medullary cavity, which harbors the bone marrow. In infants and children, this marrow cavity is filled with red marrow, whereas in...

Most bones contain compact and spongy osseous tissue, but their distribution and concentration vary based on the bone's overall function.
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...

Ultrasonography is an imaging technique that uses high-frequency sound waves to visualize the body's internal structures. It is a non-invasive and safe procedure that does not involve the use of ionizing radiation, making it widely used in various medical fields. Ultrasonography is used to study heart function, blood flow in the neck or extremities, certain conditions such as gallbladder disease, and fetal growth and development.

Within the skeletal system, the structure of a bone, or osseous tissue, can be exemplified in a long bone, like the femur, where there are two types of osseous tissue: cortical and cancellous.

01:09Spongy Bone
7.1K
All bones comprise an outer layer of compact bone, and an interior made up of spongy bone tissue, also called cancellous or trabecular bone. In long bones, spongy bone tissue is mainly found in the interior of the epiphyses (broad ends of the bone).
Spongy bone is more porous, and less dense compared to compact bone. It is composed of concentric lamellae that are arranged irregularly to form the trabecular network. In some bones, the spaces between trabeculae contain red marrow, where...

German physicist Wilhelm Röntgen (1845–1923) was experimenting with electrical current when he discovered that a mysterious and invisible "ray" would pass through his flesh but leave an outline of his bones on a screen coated with a metal compound. In 1895, Röntgen made the first durable record of the internal parts of a living human: an "X-ray" image (as it came to be called) of his wife’s hand. Scientists worldwide quickly began their own experiments with...
