Quick Answer: What Is The Medical Term For Inflammation Of The Periosteum?

What is tibial Periostitis?

A common injury for runners and people practicing certain sports (football, basketball, soccer, or dance), periostitis, also known as medial tibial stress syndrome or ‘shin splints’, is an inflammation of the periosteum, a membrane covering the tibia bone..

Is periosteal reaction Bad?

In this reaction, the periosteum has been lifted from the cortex and new bone is filling the space in a uniform manner. This reaction may be thick or thin, straight or undulating, variable in opacity, and have distinct or indistinct margins. These reactions are generally benign and usually signify benign disease.

How does the periosteum initiate healing of a fracture?

During the fracture healing, cells from the periosteum contribute significantly to callus formation. Cells from other sources, such as stem cells from muscle and adipose tissue, and pericytes from the surrounding blood vessels, are involved in callus …

What is the medical term for periosteum?

Periosteum: A dense membrane composed of fibrous connective tissue that closely wraps all bone except that of the articulating surfaces in joints, which is covered by a synovial membrane.

What is Periostitis?

Periostitis is a condition that many runners are familiar with. It is caused by inflammation of the periosteum, a layer of connective tissue that surrounds bone. The condition is generally chronic and needs to be differentiated from stress fracture or shin splints.

How long does medial tibial stress syndrome take to heal?

If symptoms recur, two additional weeks of rest are recommended and should be followed by a “downgraded” training regimen. Patients can often achieve a return to full, unrestricted activity in three to six weeks. However, a delayed return is not uncommon for this often refractory condition.

What part of bone is not covered by the periosteum?

The periosteum covers the entire outer surface except where the epiphyses meet other bones to form joints (Figure 6.3.

What are haversian systems?

Haversian canals are a series of tubes around narrow channels formed by lamellae. The Haversian canals surround blood vessels and nerve fibers throughout the bone and communicate with osteocytes. The canals and the surrounding lamellae are called a Haversian system (or an osteon).

How is periosteum formed?

Following an injury such as a fracture, the periosteal vessels bleed around the traumatized area, and a clot forms around the fragments of bone. Within two days the osteoblasts multiply, and the cambium expands to become many cell layers thick.

What is the periosteum and what does it do?

The periosteum is a complex structure composed of an outer fibrous layer that lends structural integrity and an inner cambium layer that possesses osteogenic potential. During growth and development it contributes to bone elongation and modeling, and when the bone is injured, participates in its recovery.

How is Periostitis treated?

Treatment for acute periostitis Healthcare providers use antibiotics to treat the underlying infection caused by acute periostitis. If the infection produces pus and fluid, your healthcare provider may need to drain it surgically. They may also have to remove any bone tissue that becomes necrotic from infection.

What causes periosteal reaction?

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.

What does it mean when your tibia hurts?

Shin pain generally occurs from overuse. This problem can come from irritation of the muscles or other tissues in the lower leg or from a stress fracture. This injury is most common in runners who increase their mileage or the intensity of their running, or who change the surface on which they are running.

Why is the periosteum important to bone healing?

During fracture repair, the periosteum participates in, and provides cells for, both the intramembranous ossification that bridges and stabilizes the fracture, as well as the process of endochondral ossification and remodeling that eventually reestablishes the bone’s load bearing properties.

How long does Periostitis last?

Average recovery time is 2-4 weeks for periostitis, 6-8 weeks for stress fracture and several months for compartment syndrome.

What is a Greenstick fracture?

A greenstick fracture occurs when a bone bends and cracks, instead of breaking completely into separate pieces. The fracture looks similar to what happens when you try to break a small, “green” branch on a tree. Most greenstick fractures occur in children younger than 10 years of age.

What does osteomyelitis mean?

Osteomyelitis is an infection in a bone. Infections can reach a bone by traveling through the bloodstream or spreading from nearby tissue. Infections can also begin in the bone itself if an injury exposes the bone to germs.

What causes pain in the tibial region?

Medial tibial stress syndrome (MTSS) is an overuse injury or repetitive-stress injury of the shin area. Various stress reactions of the tibia and surrounding musculature occur when the body is unable to heal properly in response to repetitive muscle contractions and tibial strain.

Does periosteum regenerate?

Purpose: The presence of a functional periosteum accelerates healing in bone defects by providing a source of progenitor cells that aid in repair. … Results: Calcium phosphate pellets wrapped in BMSC sheets regenerated a bone-like tissue, but pellets lacking the cell sheet wrap did not.

What does the periosteum cover?

The periosteum is a membranous tissue that covers the surfaces of your bones. The only areas it doesn’t cover are those surrounded by cartilage and where tendons and ligaments attach to bone. The periosteum is made up of two distinct layers and is very important for both repairing and growing bones.

What is a periosteal reaction?

Periosteal reaction, also known as periostitis or periosteitis, is a nonspecific radiographic finding that indicates periosteal irritation. Periosteal reactions may be broadly characterized as benign or aggressive, or more specifically categorized by pattern.
