Periostitis, also known as periostalgia, is a medical condition caused by inflammation of the periosteum, a layer of connective tissue that surrounds bone. [1] The condition is generally chronic and is marked by tenderness and swelling of the bone and pain.
The periosteum is a membrane that covers the outer surface of all bones, [1] except at the articular surfaces (i.e. the parts within a joint space) of long bones. (At the joints of long bones the bone's outer surface is lined with "articular cartilage", a type of hyaline cartilage .)
Examples of periosteal reactive bone in selected specimens of Triceratops. 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.
Joint pain is a common symptom we all experience at some point or another. Painful joints can have a significant impact on quality of life and the ability to do daily activities.
The septa are formed from the fascia which is made up of a strong type of connective tissue. The fascia also separates the skeletal muscles from the subcutaneous tissue. [2] Due to the great pressure placed on the leg, from the column of blood from the heart to the feet, the fascia is very thick in order to support the leg muscles. [3]
The deep fascia of leg or crural fascia forms a complete investment to the muscles, and is fused with the periosteum over the subcutaneous surfaces of the bones.. The deep fascia of the leg is continuous above with the fascia lata (deep fascia of the thigh), and is attached around the knee to the patella, the patellar ligament, the tuberosity and condyles of the tibia, and the head of the fibula.
Some of the most common symptoms are a hard immobile painless palpable mass, adjacent muscle soreness, and pressure or irritation with heavy exercising. [5] Major symptoms arise when complications such as fractures, bone deformity or mechanical joint problems occur. If the occurrence of an osteochondroma is near a nerve or a blood vessel, the ...
PGE 2 can mimic the activity of osteoblasts and osteoclasts (respectively building and breaking down bone tissue). This is why acroosteolysis and periosteal bone formation can be explained by the action of PGE 2. [10] Furthermore, PGE 2 has vasodilatory effects, which is consistent with prolonged local vasodilation in digital clubbing. [10]
