What is Osteonecrosis? What are its causes and symptoms? Can it be diagnosed and treated? Answers to these questions and more in the following article.

Introduction :

osteoporosis , Bones consist of living cells that need blood nourishment to stay healthy, and lack of blood supply leads to the death of bone tissue, and this condition is known as osteonecrosis, and the following is the most important information about this case:

Today, through the Pharma C website, we show you , Osteoporosis .

Osteonecrosis: definition?

Osteonecrosis is the death of bone tissue due to reduced blood flow to part of the bone resulting in micro-fractures of the bone and the collapse of the joint.

Osteonecrosis can affect people at any age, but it is more common in people in their thirties and forties, and it can occur in any type of bone, but it is often at the ends of long bones, such as: the thigh bone, shoulder bone, and in a few Sometimes it can occur in the bones of the elbows, ankles, feet, wrists, and hands.

What are the types of osteochondrosis?

Types of osteochondrosis include the following:

  1. Traumatic osteonecrosis: It occurs when the bone breaks into two or more parts without the bones fused identically in their correct place, which leads to the prevention of blood flow to the bones, and this type of osteonecrosis can occur as a result of joint dislocation.
  2. Nontraumatic osteonecrosis: It is caused by a medical condition that blocks blood flow to the bones, and most often affects the bones on both sides of the body.

Osteonecrosis: symptoms

There are no symptoms of osteonecrosis in its early stages, but the following symptoms may appear as the problem worsens:

  • Joint pain that increases with time.
  • Pain occurs even when at rest.
  • Limited range of motion.
  • Pain in the area between the abdomen and thigh (Grion) if the hip joint is affected.
  • Lameness if the leg bones are affected.
  • Difficulty moving the upper body if the shoulder joint is affected.

Osteonecrosis: causes

Osteonecrosis occurs as a result of interruption or reduced blood flow to the bones. Among the reasons that lead to reduced blood flow to the bones are the following:

  • An injury to a bone or a joint, such as a joint dislocation, can damage nearby blood vessels and cut off or reduce blood flow.
  • Fat deposition in small blood vessels can reduce the flow of blood that nourishes the bone.
  • Having a disease, such as: sickle cell anemia and Gaucher disease, can cause reduced blood flow to the bones.

Osteonecrosis: risk factors

Risk factors for osteoporosis include:

  • Injuries, such as: a dislocated joint or a broken bone.
  • Steroids are taken in high doses and for long periods.
  • Taking high doses of bisphosphonates for long periods of time.
  • Cancer treatment with radiation .
  • Organ transplantation, such as a kidney transplant.
  • Having one of the following diseases or medical conditions: pancreatitis, diabetes, Gaucher disease, AIDS, systemic lupus erythematosus, sickle cell anemia, decompression sickness that affects divers.
  • High consumption of alcohol and smoking.

Osteonecrosis: diagnosis

The doctor evaluates the patient’s symptoms and conducts a physical examination. One or more of the following examination methods can help detect osteonecrosis:

  • Blood tests to check for a disease or condition that could be a risk factor for osteonecrosis.
  • X-ray imaging.
  • MRI can help in early detection of osteonecrosis.
  • Bone scan.
  • Computed tomography.

It should be noted that it is necessary to inform the doctor about the medications or any nutritional supplements or vitamins that the patient is taking, as this can help in revealing the possible causes of osteoporosis.

Osteonecrosis: treatment

Once the main cause of osteochondrosis is known, part of the treatment is directed to treating the underlying problem. The next step in treatment depends on the following factors:

  • Affected bones.
  • Early or late stage of disease detection.
  • The extent of bone damage.
  • The underlying cause of the problem.
  • Age.

If the disease is detected at an early stage and affects a small area that does not carry much weight, the condition can improve with rest and physical therapy , and some analgesics, such as nonsteroidal anti-inflammatory drugs – NSAIDs, can help reduce pain and inflammation .

While these non-surgical treatments slow the progression of the disease to the worst, most people require surgical intervention that includes the following options:

  • Removing part of the inside of the bone to relieve pressure and allow new blood vessels to form.
  • Bone grafting by taking healthy bone from another part of the body and transplanting it to replace the bone affected by necrosis.
  • Cut the bone and change its place to align the other part of the broken bone to relieve pressure on the bone or on the joint.
  • Replacing the entire joint with an artificial joint.
