Avascular necrosis (AVN) is a condition that occurs when the blood supply to a bone becomes disrupted. Bones are living tissues that depend on a steady flow of blood to remain healthy and strong. When this blood supply is reduced or blocked, the bone tissue can begin to die. This process is known as osteonecrosis, which literally means “bone death.”

Most tissues in the body receive blood from multiple sources. If one vessel becomes damaged, others may still supply enough blood to keep the tissue alive. However, some joints have a limited blood supply. One of these is the hip joint. Because the hip relies on only a few blood vessels, damage to these vessels can lead to avascular necrosis of the hip, often resulting in hip pain, stiffness, and reduced mobility.

Anatomy

The hip joint is a classic ball-and-socket joint that allows a wide range of movement while supporting body weight. The socket portion of the joint is called the acetabulum. It forms a deep cup that holds the rounded top of the thigh bone.

The thigh bone is known as the femur. The rounded upper end of this bone is called the femoral head. This ball-shaped structure fits inside the acetabulum to form the hip joint. Thick muscles surrounding the joint, including the buttock muscles at the back and the strong thigh muscles at the front, provide stability and support.

Both the femoral head and the inside of the acetabulum are covered with articular cartilage. This smooth and durable material allows the joint surfaces to glide against each other with minimal friction.

The blood supply to the femoral head enters primarily through the femoral neck, which is the narrower section of bone connecting the head to the shaft of the femur. If these blood vessels become damaged, there is very little alternative circulation to compensate.

When blood flow stops, the bone cells in the femoral head begin to die. Healthy bone normally repairs itself constantly through a natural cycle of breakdown and rebuilding. Without blood supply, this process stops. Over time the bone weakens and may collapse under body weight.

When collapse occurs, the round shape of the femoral head becomes flattened. As a result, the joint no longer fits together properly. The abnormal contact between the ball and socket leads to joint damage and often progresses to osteoarthritis of the hip.

Causes

Many factors can interfere with the blood supply to the hip and lead to avascular necrosis.

Direct injury to the hip joint is one of the most common causes. A fracture of the femoral neck can damage the small blood vessels that supply the femoral head. A hip dislocation can also tear or compress these vessels. In many cases, AVN develops months after the original injury and sometimes appears up to two years later.

Certain medications are also associated with avascular necrosis. Corticosteroid medications such as prednisone or methylprednisolone are the most frequently linked drugs. These medications are often prescribed to treat severe inflammation, autoimmune disease, or to prevent rejection after organ transplantation.

In some cases, AVN develops in patients who must take corticosteroids for extended periods. Research has also shown that individuals who use corticosteroids together with cholesterol-lowering medications known as statins may have a higher risk of developing femoral head osteonecrosis.

Lifestyle factors may also contribute. Smoking can narrow blood vessels and reduce circulation to areas that already have a limited blood supply, such as the hip joint. Excessive alcohol use can also damage blood vessels and interfere with normal blood flow to the bone.

Certain occupations carry increased risk. Divers and miners who work under high atmospheric pressure may develop tiny gas bubbles in the bloodstream. These bubbles can block small blood vessels and reduce blood flow to the hip.

A number of medical conditions are also linked to avascular necrosis. These include blood disorders such as leukemia and sickle cell disease, infections such as HIV, and metabolic conditions like Gaucher disease or hyperuricemia, which is commonly known as gout. Caisson disease, which is related to decompression illness, may also affect blood circulation to the bones.

Symptoms

Pain is usually the earliest symptom of avascular necrosis of the hip. The discomfort often appears when weight is placed on the affected hip during standing or walking.

Many people feel the pain deep in the groin area. It may also spread to the buttock or travel down the front of the thigh. As the condition progresses, walking may become more difficult and a limp can develop.

Stiffness in the hip joint gradually increases as the bone damage worsens. Over time the pain may occur even when resting and can eventually interfere with sleep.

Diagnosis

Diagnosis begins with a detailed medical history and physical examination. The physician may ask questions about your work activities, previous injuries, medications, and lifestyle factors such as alcohol consumption.

During the examination the doctor will assess hip movement, joint stiffness, and walking patterns. A limp or reduced range of motion may indicate joint involvement.

Imaging tests are usually required to confirm the diagnosis. X-rays are typically the first test performed. In later stages of avascular necrosis, X-rays may reveal collapse of the femoral head or signs of arthritis within the joint.

However, AVN may not appear on X-rays during the early stages even when symptoms are present. In such cases additional imaging tests may be recommended.

A bone scan can sometimes be used to detect areas of reduced blood supply. This test involves injecting a small tracer into the bloodstream and using a specialized camera to visualize bone activity.

Today, magnetic resonance imaging (MRI) is the most commonly used method for detecting early avascular necrosis. MRI scans provide highly detailed images of bone tissue and can identify small areas of reduced blood flow shortly after they develop.

These imaging studies allow physicians to determine the extent of bone damage and classify the condition as mild, moderate, or severe. This classification helps guide the treatment plan.

Treatment

Treatment decisions depend on several factors, including the stage of the condition, the severity of symptoms, age, activity level, and overall health.

In some cases, especially when other serious medical conditions are present, treatment may focus on reducing symptoms rather than performing surgery. Pain medications and anti-inflammatory drugs can help relieve discomfort, but they cannot restore the blood supply to the bone.

Nonsurgical Treatment

When avascular necrosis is diagnosed early, conservative treatment may help slow the progression of the condition.

Reducing weight-bearing on the affected hip can be beneficial. Patients may use crutches or a walker to limit pressure on the joint during standing and walking. This approach aims to protect the weakened bone and reduce further damage.

Gentle stretching exercises may be recommended to help maintain mobility and prevent stiffness in the hip joint.

Anti-inflammatory medications are often used to relieve pain. Certain medications known as bisphosphonates may also be prescribed in some cases. One example is Fosamax, which is commonly used to treat osteoporosis. Research suggests that this medication may help reduce the risk of femoral head collapse in some patients with avascular necrosis.

In certain situations, physicians may recommend additional therapies such as electrical stimulation or shock wave therapy to support bone healing. These approaches may delay the progression of the condition, although they rarely reverse the damage completely.

Physical therapy may also play a role in conservative care. A therapist can guide you through safe movements and exercises designed to maintain joint flexibility and improve function. Learning how to move and walk safely while protecting the hip joint is an important part of the recovery process.
