Stages of Avascular Necrosis (AVN) of the Hip: A Guide for Early Intervention

Avascular Necrosis (AVN) of the hip, also known as osteonecrosis, disrupts blood flow to the hip joint, leading to bone degeneration and potential collapse. This can cause significant pain and limit mobility. Understanding the different stages of AVN is crucial for seeking timely intervention and achieving the best possible outcomes. Dr. Vatsal at the Khetan Knee Shoulder Clinic explains the stages of AVN of the hip and what each signifies.

Stage 0: Preclinical Phase

Why It’s Important: This stage represents the early development of AVN before symptoms become apparent.

What You Need to Know: Diagnostic tests like X-rays might appear normal at this stage. However, if you have risk factors for AVN (discussed in a previous blog), close monitoring by a healthcare professional is recommended.

Stage I: Early AVN

Why It’s Important: Identifying early signs of AVN allows for prompt intervention and potentially better treatment outcomes.

What You Need to Know: Imaging tests like MRI scans may reveal initial abnormalities in the bone, but the hip joint itself remains intact. If you experience any hip pain, especially after an injury or with a known risk factor, consulting Dr. Vatsal for evaluation is crucial.

Stage II: Moderate AVN

Why It’s Important: The disease has begun to compromise the bone’s integrity, necessitating immediate action.

What You Need to Know: X-rays typically show signs of bone softening at this stage. Early surgical intervention, such as core decompression, may be beneficial to preserve the joint.

Stage III: Advanced AVN

Why It’s Important: The condition has progressed significantly, with the joint beginning to collapse.

What You Need to Know: Surgical options like bone grafting or osteotomies might be explored to attempt to salvage the joint, depending on the severity. Dr. Vatsal can discuss these options with you in detail.

Stage IV: End-Stage AVN

Why It’s Important: At this advanced stage, the disease has severely affected the bone and surrounding cartilage.

What You Need to Know: Total hip replacement surgery is often the most effective treatment option to restore pain-free mobility and function at this stage. Dr. Vatsal is a highly skilled hip replacement surgeon and can guide you through the process.

Early diagnosis and treatment are critical for managing AVN of the hip. If you experience persistent hip pain, especially with a risk factor for AVN, consult Dr. Vatsal at the Khetan Knee Shoulder Clinic.
