Clinical Description of Osteonecrosis

Definition

Osteonecrosis, also known as avascular necrosis, occurs when blood flow to a bone is disrupted, leading to the death of bone cells. This condition can affect any bone but is most commonly seen in the hip, knee, and shoulder joints. When it specifically involves the right foot, it can impact various structures, including the metatarsals, phalanges, and tarsal bones.

Etiology

The causes of osteonecrosis can vary widely and may include:
- Trauma: Fractures or dislocations that damage blood vessels.
- Chronic steroid use: Long-term use of corticosteroids can interfere with blood supply.
- Alcoholism: Excessive alcohol consumption can lead to fatty deposits in blood vessels, reducing blood flow.
- Medical conditions: Conditions such as sickle cell disease, lupus, and certain infections can also contribute to the development of osteonecrosis.

Symptoms

Patients with osteonecrosis of the right foot may experience:
- Pain: Often a deep, aching pain that worsens with weight-bearing activities.
