What is Necrosis?

Understanding and Managing Tissue Death

When you hear the term necrosis, it might sound like something out of a medical thriller. But for many, it’s a reality that needs understanding and management. In simple terms, necrosis refers to the death of body tissue or cells due to a lack of blood supply. But what does this mean for those affected, and how can one manage or recover from necrosis? The medical professionals at Northeast Knee & Joint Institute can help with wound care and wound healing.

What is Necrosis?

Necrosis is characterized by the irreversible death of cells and tissues, often marked by distinct changes in color, odor, and texture. Necrotic tissue can appear brown, gray, or black, and is typically associated with a strong, unpleasant smell. The texture is usually flimsy, lacking the ability to granulate or bleed, which differentiates necrotic tissue from healthy tissue.

Types of Necrosis

There are two primary types of necrotic tissue found in wounds—eschar and slough.

• Eschar is dry, thick, and leathery, often presenting in shades of tan, brown, or black.
• Slough, on the other hand, appears moist, loose, and stringy, ranging in color from yellow to green.

Causes of Necrosis

Necrosis can result from various factors that impede blood flow and oxygen to tissues. Some common causes include:

1. Trauma: Injuries from accidents or surgeries can damage blood vessels, limiting blood flow to tissues.
2. Infections: Bacteria, viruses, fungi, and parasites can invade and destroy healthy tissue.
3. Hypoxia: Oxygen deprivation, known as hypoxia, often leads to necrosis.
4. Environmental Factors: Exposure to extreme heat, cold, radiation, or ultraviolet light can inflict damage.
5. Medications and Alcohol: Prolonged use of corticosteroids or excessive alcohol consumption is linked to necrosis.
6. Diseases: Conditions like sickle cell anemia or Gaucher’s disease interfere with blood supply to tissues.
7. Cancer Treatments: Radiation therapy can weaken bones and disrupt blood vessels, leading to tissue death.
8. Fatty Deposits: These can block small blood vessels, reducing blood flow to bones and surrounding tissue.

Symptoms

Recognizing necrosis early can be crucial for effective treatment. Symptoms often include:

• Discoloration of the skin
• A foul-smelling odor from the affected area
• Pain or tenderness in the region
• Swelling or redness
• A loss of sensation or numbness

Prompt attention to these symptoms can prevent further complications.

Diagnosis

Diagnosing necrosis involves a thorough medical examination. Doctors may use imaging tests like MRI or CT scans to assess the extent of tissue damage. Lab tests may also be conducted to identify any infections causing or exacerbating necrosis.

Overview of Necrosis Treatments

Treatment for necrosis is multifaceted. It first aims to remove dead tissue, restore blood supply, and manage pain. The approach depends on the necrosis type, its location, and severity.

Surgical and Non-Surgical Interventions

1. Surgical Debridement: This procedure involves removing dead tissue to prevent infection spread and promote healing.
2. Antibiotics: Used to treat any underlying infections that may have led to or resulted from necrosis.
3. Hyperbaric Oxygen Therapy: Patients breathe 100% oxygen in a pressurized chamber, enhancing wound healing.
4. Vaccines: The tetanus vaccine may be administered to prevent further infections.
5. Core Decompression: A surgical technique where holes are drilled into the bone to improve blood flow.
6. Bone Graft: Transplanting healthy bone from another body part can strengthen affected areas.
7. Bone Reshaping (Osteotomy): Removing a wedge of bone helps redistribute weight away from the damaged area.
8. Joint Replacement: Severe cases might require replacing the damaged joint with an artificial one.
9. Bone Marrow Aspirate and Concentration: Stem cells from bone marrow are injected into dead hipbone areas to promote recovery.

Early intervention is crucial in managing necrosis, as it prevents the spread of tissue death and minimizes complications. Patients should not attempt home treatments but seek professional medical assistance to ensure comprehensive care.
