Understanding Core Decompression for AVN

Core decompression is a surgical procedure used to treat certain stages of Avascular Necrosis (AVN), particularly when the femoral head has not yet collapsed. The procedure involves creating channels within the affected bone to reduce pressure and support blood flow and bone healing. Core decompression is not automatically the only treatment option for every person diagnosed with AVN. The appropriate treatment depends on the stage of AVN, location and extent of bone involvement, symptoms, femoral head integrity, imaging findings, age, activity level and overall health. A detailed evaluation helps determine whether a non-surgical regenerative orthopedic approach can be considered for preserving the natural hip joint and managing the condition.

What Can Cause Avascular Necrosis?
AVN occurs when the blood supply to bone tissue becomes compromised. Common contributing factors include:

Long-term corticosteroid use

Excessive alcohol consumption

Previous hip trauma

Hip fractures

Hip dislocation

Certain medical conditions

Blood clotting disorders

Radiation exposure

Certain medications

Previous surgery

In some cases, no specific cause is identified

Common Symptoms of AVN

Deep hip pain
Groin pain
Pain while walking
Pain during exercise
Hip stiffness
Reduced range of motion
Limping
Pain while standing
Difficulty climbing stairs
Difficulty performing daily activities

When Should You See an AVN Specialist?

Seek specialist evaluation if you experience:
Persistent hip or groin pain
Pain while walking
Increasing hip stiffness
Difficulty putting weight on the affected leg
Reduced hip movement
Limping
Pain following a hip injury
MRI findings suggesting AVN
Persistent symptoms despite conservative treatment
Difficulty continuing work, exercise or sports
Early diagnosis is important because treatment options depend significantly on whether the femoral head has maintained its shape or has already developed structural collapse.

Stages and Conditions Associated With Core Decompression for AVN

Early-Stage AVN

Symptoms

  • Mild or moderate hip pain
  • Groin discomfort
  • Pain during activity
  • Occasional stiffness
  • Reduced exercise tolerance

Causes

Early-stage AVN develops when the blood supply to the femoral head is compromised and bone tissue begins to deteriorate.

Diagnosis

MRI is highly sensitive for detecting early AVN and can identify areas of bone involvement before significant structural changes appear on X-rays.

Non-Surgical Treatment

For appropriate early-stage cases, regenerative orthopedic treatments such as Bone Marrow Concentrate (BMAC), High-Concentrated PRP and other image-guided treatments can be considered alongside activity modification and rehabilitation.

Symptoms

  • Persistent hip pain
  • Groin pain
  • Pain with weight-bearing
  • Reduced hip movement
  • Difficulty exercising
  • Increasing functional limitations

Causes

Pre-collapse AVN involves structural changes within the femoral head while the overall shape of the femoral head remains preserved.

Diagnosis

MRI helps identify the location and extent of the affected bone. X-rays are used to evaluate the overall structure of the femoral head.

Non-Surgical Treatment

A regenerative orthopedic approach can be considered for appropriate pre-collapse AVN. Treatment can include BMAC, PRP, Platelet Lysate and rehabilitation based on the stage and characteristics of the condition.

Symptoms

  • Significant hip pain
  • Severe stiffness
  • Difficulty walking
  • Limping
  • Reduced range of motion
  • Pain during daily activities
  • Difficulty exercising

Causes

Progressive AVN can weaken the femoral head and eventually cause structural collapse.

Diagnosis

X-rays and MRI help determine whether collapse has occurred and assess the extent of joint damage.

Non-Surgical Treatment

Once significant femoral head collapse and advanced joint degeneration are present, non-surgical treatment options become more limited. A specialist evaluation is necessary to determine whether joint-preserving treatment is appropriate or whether surgical treatment should be considered.

Symptoms

  • Pain in both hips
  • Difficulty walking
  • Bilateral stiffness
  • Reduced activity tolerance
  • Difficulty exercising
  • Progressive mobility limitations

Causes

AVN can affect both hips, particularly when an underlying systemic factor contributes to reduced blood supply to the bone.

Diagnosis

MRI of both hips can identify early changes that might not yet be visible on standard X-rays.

Non-Surgical Treatment

Treatment depends on the stage of AVN in each hip. Regenerative orthopedic treatments, activity modification and rehabilitation can be considered for appropriate pre-collapse disease.

Signs You Shouldn't Ignore

Persistent hip pain should not be ignored, especially when AVN is suspected. Early-stage AVN can present with relatively mild symptoms while structural changes are already developing within the femoral head.
Watch for:
  • Persistent groin pain
  • Deep hip pain
  • Pain while walking
  • Pain during weight-bearing
  • Increasing hip stiffness
  • Reduced hip range of motion
  • Limping
  • Difficulty climbing stairs
  • Pain during exercise
  • Difficulty putting on shoes or socks
  • Hip pain following trauma
  • MRI findings showing bone changes
A specialist evaluation helps determine the stage of AVN and whether a joint-preserving approach is appropriate.

How We Diagnose AVN Before Considering Core Decompression

Accurate staging is essential before deciding whether core decompression or another treatment approach is appropriate. At RegenOrthoSport, the hip is evaluated comprehensively to determine the extent of bone involvement and the condition of the femoral head.

Medical History

The evaluation includes the onset of symptoms, previous hip injuries, corticosteroid exposure, alcohol use, medical conditions, medications, previous treatments and activity level.

Physical Examination

The hip is assessed for range of motion, strength, gait, tenderness and pain during specific movements.

X-rays

X-rays help evaluate the shape of the femoral head, joint space, bone structure and evidence of collapse.

MRI

MRI is particularly important for AVN because it can identify early bone changes, determine the location and extent of necrosis and evaluate whether femoral head collapse has occurred.

AVN Staging

The imaging findings are used alongside the clinical examination to determine the stage of AVN and identify appropriate treatment options.

Functional Assessment

Walking, hip mobility, strength and functional limitations are assessed to understand how AVN affects work, daily activities, exercise and sports.

Frequently asked
questions

What are the symptoms of AVN of the hip?

Common symptoms include pain in the hip or groin, stiffness, reduced range of motion and difficulty with activities such as walking, climbing stairs or standing for prolonged periods. Some people have few symptoms during the early stages.

AVN-related pain is commonly felt in the groin or hip. It can also extend toward the thigh, buttock or knee. The location and severity of pain can vary depending on the extent of femoral head involvement.

Yes. Hip problems can sometimes cause referred pain that is felt around the knee. When knee pain occurs along with hip symptoms, evaluating the hip can help determine whether the pain is originating from the hip joint.

Yes. AVN can affect both hips. When AVN is diagnosed in one hip, the other hip may also be evaluated, particularly when there are risk factors associated with bilateral disease.

Femoral head collapse occurs when weakened bone within the femoral head loses its structural integrity and the normally rounded shape of the femoral head becomes altered. This can lead to progressive joint damage and worsening hip symptoms.

AVN results from impaired blood supply to the bone, leading to bone damage within the femoral head. Hip osteoarthritis primarily involves progressive degeneration of the joint surfaces and surrounding structures. Advanced AVN can eventually lead to secondary osteoarthritis.

AVN can cause progressive damage to the femoral head if the condition advances. Loss of structural integrity and femoral head collapse can result in permanent changes to the hip joint.

Yes. Pain, stiffness, reduced hip movement and progression of femoral head damage can make walking difficult. The degree of walking difficulty varies with the stage and extent of AVN.

Yes. Early AVN can sometimes produce few or no noticeable symptoms. AVN may also be identified incidentally during imaging performed for another reason.

AVN staging is based on clinical assessment and imaging findings, particularly MRI and X-rays. The evaluation considers the location and extent of bone involvement and whether structural changes or femoral head collapse are present.

Pre-collapse AVN means that the affected portion of the femoral head has not yet undergone significant structural collapse. Identifying AVN before collapse is important when considering joint-preserving treatment approaches.

Post-collapse AVN refers to AVN in which the femoral head has developed structural collapse or deformity. Treatment options at this stage are influenced by the extent of collapse and the condition of the hip joint.

Yes. Prolonged or high-dose corticosteroid exposure is an established risk factor for AVN. The risk varies according to factors such as dosage, duration and individual susceptibility.

Excessive alcohol consumption is associated with an increased risk of AVN. Alcohol-related AVN is thought to involve changes that affect bone health and blood supply to the femoral head.

Yes. Trauma such as a hip fracture or dislocation can damage the blood vessels supplying the femoral head and increase the risk of AVN.

The course of AVN varies, but progressive disease can lead to weakening and collapse of the femoral head. Once collapse occurs, damage to the hip joint can become more extensive.

Follow-up frequency depends on the stage of AVN, symptoms, imaging findings and treatment plan. Your specialist can determine when repeat clinical assessment or imaging is appropriate.

Yes. Depending on its severity, AVN can interfere with walking, standing, climbing stairs, sitting for prolonged periods and other daily activities involving the hip.

Weight-bearing places mechanical stress on the femoral head. In some cases, activity and weight-bearing may need to be modified to reduce stress on the affected hip, particularly when the bone is structurally compromised.

AVN can progress or develop in another area of the hip or the opposite hip depending on the underlying cause and individual risk factors. Ongoing clinical and imaging follow-up can help monitor the condition.
