What does a periosteal reaction mean?

Periosteal reaction is a nonspecific radiographic finding that indicates new bone formation in reaction to the abnormal stimulants. Periosteal reactions may be broadly characterized as benign or aggressive, or more specifically categorized by pattern.

What causes periosteal reaction?

Periosteal reaction results when cortical bone reacts to one of many possible insults. Tumor, infection, trauma, certain drugs, and some arthritic conditions can elevate the periosteum from the cortex and form various patterns of periosteal reaction (Fig.

How is periosteal reaction treated?

Take a break from high-impact activities, such as running or jumping. Try going with more low-impact exercises, such as biking or swimming. Applying ice can bring down swelling and reduce inflammation. Taking an anti-inflammatory medication, such as ibuprofen (Advil), may also help.

What causes periosteal new bone formation?

A periosteal reaction can result from a large number of causes, including injury and chronic irritation due to a medical condition such as hypertrophic osteopathy, bone healing in response to fracture, chronic stress injuries, subperiosteal hematomas, osteomyelitis, and cancer of the bone.

Is periosteal reaction normal?

What is a reactive bone lesion?

Reactive lesions of bone and soft tissue can appear alarming on histologic examination because they are often cellular and have atypical (activated) cytologic features, such as distinct nucleoli and mild hyperchromasia, and mitotic activity.

What causes periosteal thickening?

The causes of periosteal reaction are broad, including trauma, infection, arthritis, tumors, and drug-induced and vascular entities. When periosteal reaction occurs in a bilateral distribution, a systemic disease process should be considered.

Can a bone lesion be benign?

Bone lesions are areas of bone that are changed or damaged. Causes of bone lesions include infections, fractures, or tumors. When cells within the bone start to divide uncontrollably, they are sometimes called bone tumors. Most bone lesions are benign, meaning they are not cancerous.

Are lesions on bones always cancerous?

Most bone lesions are benign, meaning they are not cancerous. Some bone lesions are cancerous, however, and these are known as malignant bone tumors.

Can Covid cause bone lesions?

Simultaneously, this virus can affect the development of bone metabolism to a certain degree. We should attach attention to SARS-CoV-2 infection-related bone destruction in the setting of this pandemic and beware of the clinical management of COVID-19 patients in orthopedics.

How does COVID-19 affect the muscular and skeletal system?

COVID-19 induced proinflammatory state may lead to inflammatory reactive arthritis, muscle fibrosis, increased bone fragility, tendinopathy, and muscle weakness. Arthralgia and myalgia commonly present early in COVID-19 patients, even in the absence of pulmonary symptoms, with myalgia occurring more commonly.

Can COVID cause arthritis to flair up?

There are sporadic reports suggesting that some people with COVID-19 developed inflammatory arthritis as a complication of the infection. While COVID-19 survivors have reported muscle and joint pain, there have not been any studies showing that these individuals demonstrated markers of inflammatory arthritis.
