OSTEONABROSIS Meaning and
Definition
-
Osteonabrosis is a medical condition characterized by the decreased or inadequate blood supply to the bone, resulting in the death or necrosis of bone tissue. It is a term that is primarily used in orthopedics and refers to the pathological condition commonly known as avascular necrosis.
In osteonabrosis, the impaired blood circulation to the bone prevents the delivery of oxygen and essential nutrients to the affected areas. Consequently, the lack of blood flow leads to the death of bone cells, causing progressive damage to the bone structure. This condition most commonly occurs in large weight-bearing joints such as the hip, knee, and shoulder.
Osteonabrosis may arise due to various underlying causes, including trauma, excessive steroid use, alcohol abuse, certain medical conditions (such as sickle cell anemia or systemic lupus erythematosus), and the use of certain medications. Symptoms of osteonabrosis often include persistent joint pain, limited range of motion, swelling, and stiffness.
The diagnosis of osteonabrosis typically involves a combination of physical examination, medical history review, imaging tests (such as X-rays, magnetic resonance imaging (MRI) scans, or bone scans), and sometimes a small sample of the affected bone may be taken (biopsy) for laboratory analysis.
Treatment for osteonabrosis often depends on the stage and location of the disease. Conservative approaches such as pain management, anti-inflammatory medications, and physical therapy may be beneficial in the early stages. However, more advanced cases may require surgical intervention, which can range from bone grafts, replacement of the affected joint, or removal of the dead bone tissue.

Etymology of OSTEONABROSIS
The word "Osteonabrosis" is a medical term that combines the roots "osteo-" and "necrosis".
The root "osteo-" comes from the Greek word "osteon", which means "bone". In medical terms, "osteo-" is commonly used to indicate something related to bone.
The term "necrosis" comes from the Greek word "nekrosis", which means "death". It is used in medical terminology to refer to the death of cells or tissues.
So "Osteonabrosis" can be understood as a condition involving the death or decay of bone tissue.
