Medullization of Bones

Bone medullization: what is it and how does it happen?

Bone medullization is the process of replacing bone substance with bone marrow. Bone marrow consists of hematopoietic tissue cells that produce blood. It has a liquid consistency and is found inside the bones.

When bone medullization occurs, hard bone substance is replaced by soft bone marrow. This process can occur naturally or as a result of injury or disease.

Natural medullization of bone occurs throughout a person’s life. In newborn babies, bone marrow is found in most of the bones, but as they grow older, many of the bones are replaced by hard bone material. However, some bones, such as the pelvis, sternum and ribs, retain their soft marrow throughout life.

Bone medullization can also occur as a result of injury or disease. For example, when bones are fractured, the bone marrow may be damaged and replaced with hard bone material. Bone cancer can also lead to medullization of the bone because the tumor can replace bone marrow.

Bone medullization can lead to impaired bone function because bone marrow is an important source of hematopoietic tissue. When bone marrow is replaced with hard bone matter, the process of blood formation may be disrupted, which can lead to anemia and other blood diseases.

In general, bone medullization is the natural process of replacing bone matter with soft bone marrow. However, with injury or disease, this process can be disrupted, which can affect the functioning of bones and the hematopoietic system.

Bone medullization (synonym - osteomyelization; from the Latin Medulla “bone marrow, environment for cell growth and development”) is a pathological replacement of normal bone elements of tubular bone tissue with cystic tumor-like growths with a predominance of carious skeleton. The disease occurs in 2-7% of all patients with osteoporosis and is the basis of the disease “periostoostosis”.

In children as a complication of chronic hidradenitis. Characteristic is bilateral damage to tubular bones without damage to flat bones. Several clinical forms of the disease have been described: marbled, cystic and tubular medlisates. The marble form is characterized by the absence of pain; X-rays reveal a sharp decrease in the density and delineation of the bone pattern in the affected hand. In the racemose form, single or multiple tight-elastic cysts that can be felt under the skin appear. The cyst enlarges slightly; on the radiograph, the bone tumor deforms the normally developed cortical parts of the bone. The tubular form is characterized by the formation of identical cysts that penetrate the bone, sometimes forming cracks or necrotic changes (sclerosis). Diagnosis is made using a plain radiograph. Radiation treatment.

The symptoms of osteomyelitis determine primarily its clinical form. Septi

Meduplysation of bone tissue

Meduplysasia (medullation) is a pathological process that leads to the growth of spongy bone in any part of the skeleton. This phenomenon can be observed in the process of post-traumatic osteogenesis. As a rule, medulation develops with closed fractures of long bones, when the integrity of only the periosteum is broken or it is completely lost. It should be noted that the pathology can be either an isolated case or one of the signs of secondary osteomyelitis caused by a bacterial infection. However, it should be noted that this is one of the few traumatic complications that often persists for a long period of time. To confirm the diagnosis, the following studies are performed:

* X-ray of the pathological focus; * MRI; * contrast myelography.

Thanks to drug support, positive dynamics can be achieved, but subsequently the affected areas can form new bones.
