subperiostale

Subperiosteal refers to a location or layer situated beneath the periosteum. The periosteum is a tough, fibrous membrane that covers the outer surface of all bones, except for the articular surfaces of joints. This membrane is crucial for bone growth, repair, and nutrition.

When a condition or procedure is described as subperiosteal, it means it occurs in the space between the bone tissue and the periosteum. For example, a subperiosteal hematoma is a collection of blood that forms between the periosteum and the bone. This can happen as a result of trauma, such as a direct blow to the bone, or in certain medical conditions.

Subperiosteal abscesses are another example, representing a collection of pus that forms in the subperiosteal space. These are typically caused by bacterial infections that spread to the bone. Surgical interventions may sometimes involve accessing or manipulating the subperiosteal space. Understanding the subperiosteal layer is important in various medical specialties, including orthopedics, oral surgery, and radiology, for diagnosing and treating conditions affecting the skeletal system.
