What is Avascular Necrosis (AVN)?
Avascular Necrosis (AVN), also known as osteonecrosis, is a painful and progressive medical condition that occurs when the blood supply to a bone is disrupted. Without adequate blood flow, bone tissue begins to die, leading to the weakening and eventual collapse of the affected bone. Although AVN can occur in any bone, it most commonly affects the hip joint, particularly the head of the femur.
At YKOrthopaedics, under the expert guidance of Dr. Yugal Karkhur, patients receive advanced diagnostic evaluations and personalized care plans for managing AVN effectively. Recognized for offering comprehensive AVN Treatment in Delhi NCR, the clinic ensures that patients understand their condition and receive the most suitable treatment options.
Causes of Avascular Necrosis
AVN can occur due to several factors. The most common causes include:
-
Trauma: A severe injury or fracture can damage the blood vessels supplying the bone.
-
Prolonged Steroid Use: Long-term or high-dose corticosteroids can interfere with the body’s ability to maintain healthy bone tissue.
-
Excessive Alcohol Intake: Alcohol can lead to fatty deposits in blood vessels, restricting blood flow.
-
Medical Conditions: Disorders such as lupus, sickle cell disease, and pancreatitis may increase the risk of AVN.
-
Idiopathic Causes: In some cases, AVN develops without an identifiable cause.
Symptoms of AVN
In the early stages, AVN may not show any symptoms. However, as the condition progresses, patients may experience:
-
Persistent pain in the hip, knee, shoulder, or other affected joints
-
Increased pain during movement or weight-bearing activities
-
Limited range of motion
-
A feeling of instability in the joint
Because symptoms often worsen with time, early diagnosis is crucial for preventing long-term damage. Consulting an experienced specialist like Dr. Yugal Karkhur, often regarded as one of the Best Orthopaedic Surgeons in Delhi NCR, can help ensure timely intervention.
How is AVN Diagnosed?
Diagnosis typically involves a detailed clinical evaluation, followed by imaging tests such as:
-
X-rays to detect structural changes
-
MRI scans, which can identify AVN in its earliest stages
-
CT scans for a more detailed view of bone integrity
Early detection often allows patients to avoid more invasive treatments later.
Treatment Options for AVN
The right treatment depends on the stage of AVN, the damage already caused, and the patient’s age and overall health. At YKOrthopaedics, the treatment plan may include:
-
Medications for pain management and bone protection
-
Physiotherapy to maintain mobility and reduce stress on affected joints
-
Core Decompression, a surgical procedure that relieves pressure and improves blood flow
-
Bone Grafting, where healthy bone tissue is transplanted to support regeneration
-
Joint Replacement Surgery, recommended for advanced AVN where the joint structure has collapsed
With advancements in orthopaedic care, many patients can return to normal activities with the right combination of therapies.
