What is Ficat and Arlet classification?

The Ficat and Arlet classification uses a combination of plain radiographs, MRI, and clinical features to stage avascular necrosis of the femoral head.

What is Ficat stage2?

2. Ficat described a four stage (I through IV) classification system, which is based on standard radiographs. 6. In Stage I the radiographs are normal. In Stage II the contour of the femoral head is normal but the radiographs show evidence of bone remodeling including cystic and sclerotic areas.

What are the stages of AVN?

What is the Steinberg Classification System for femoral head avascular necrosis (AVN)?

• Stage I – Normal radiographs; abnormal MRI or bone scan.
• Stage II – Abnormal lucency or sclerotic site in femoral head.
• Stage III – Subchondral collapse (ie, crescent sign) without flattening of femoral head.

What is Ficat stage3?

Ficat Classification of Osteonecrosis of the Hip 4 Stage I = normal radiographic appearance. Stage II = transition phase. Stage III = sequestrum with subchondral collapse. Stage IV = decreased joint space and collapse of the femoral head.

Is core decompression successful?

Core decompression is typically successful for 50-90% of patients. Its success depends on the amount and location of bone death in a joint, how much weight the joint tends to bear and other factors.

What is necrosis of the hip?

Osteonecrosis of the hip is a painful condition that occurs when the blood supply to the head of the femur (thighbone) is disrupted. Because bone cells need a steady supply of blood to stay healthy, osteonecrosis can ultimately lead to destruction of the hip joint and severe arthritis.

What does AVN pain feel like?

Avascular Necrosis (AVN), or also called osteonecrosis, can affect the hip by reducing blood flow to the femoral head in the leg. Hip pain is the first sign and it can get worse. A dull, throbbing pain can be felt in the hip and radiate to the groin or buttock.

What is 4th AVN?

Stage 4: This stage is characterized by a wide collapse of the subchondral bone and destruction of the underlying trabecular pattern. This can lead to secondary arthritis. Stage 5: The final stage where both articular surfaces are affected, which leads to a dysfunctional joint.

Is AVN curable without surgery?

The use of stem cells in treating AVN is a promising minimally-invasive, non-surgical treatment option to halt the progression of the disease and heal the dead tissue. Stem cell therapy for avascular necrosis helps to avoid total hip arthroplasty surgery.

Can AVN be treated without surgery?

How many days rest after core decompression?

What to Expect After Core Decompression. Typically, procedures that involve core decompression—which may or may not also include a bone graft or injection of organic materials—take 6 to 12 months to heal fully. You may or may not need to stay overnight in the hospital.

Can dead bone regenerate?

Bone needs circulating blood to regenerate and repair itself so you can have pain free, healthy joint motion.
