The periosteum, a bone covering, forms new bone in response to various conditions. Its reaction patterns, from solid to spiculated, help diagnose bone lesions and assess their aggressiveness.
Area of Science:
- Orthopedics
- Radiology
- Pathology
Background:
- The periosteum is a dynamic membrane crucial for bone modeling and remodeling.
- It possesses osteogenic potential, producing new bone in response to stimuli like infections and tumors.
Purpose of the Study:
- To detail the anatomy, histology, and physiology of the periosteum.
- To review diverse periosteal reaction patterns and their correlation with radiological and histopathological findings.
Main Methods:
- Review of periosteal anatomy, histology, and physiology.
- Analysis of radiological and histopathological features of periosteal reactions.
- Correlation with clinical and laboratory data.
Main Results:
- Periosteal reactions vary in configuration based on the pace and modality of bone production.
- Solid reactions indicate benign, slow-growing lesions; lamellar reactions suggest intermediate aggressiveness.
- Spiculated, interrupted, or complex reactions are associated with aggressive, fast-growing diseases.
Conclusions:
- Evaluating periosteal reactions aids in diagnosing bone lesions and determining their aggressiveness.
- Combined radiological, histopathological, and clinical data optimize etiological diagnosis and patient management.

Gross Anatomy of Bone
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...

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...
