This article provides an in-depth look at Avascular Necrosis (AVN), focusing on the treatment options available in Delhi. It is designed for patients seeking reliable information about AVN and its management — particularly those considering surgical interventions like hip replacement.
What is Avascular Necrosis (AVN)?
Avascular Necrosis (AVN) is a condition where the blood supply to a bone is disrupted, leading to bone damage. Most of the time, it happens in the hip joint — our hip is a ball-and-socket joint, and in AVN the blood supply to the ball (the femoral head) is cut off. This causes the bone to become weak and eventually collapse, leading to pain, mobility issues, and ultimately arthritis of the joint.
AVN can occur in younger age groups and often makes daily activities challenging, impacting both personal and professional aspects of life.
Symptoms and Signs
Common signs that may indicate AVN of the hip include:
- Pain in the hip region
- Difficulty in walking and taking long steps
- Limited range of motion in the legs
- Challenges in performing daily activities like climbing stairs or driving
- Visible changes in gait, such as taking small steps
Causes and Risk Factors
AVN occurs when the blood supply to a bone is interrupted, weakening it from within. In about 90% of cases the precise trigger remains unknown, but several risk factors are well established. Most scientists believe a confluence of circumstances acting together — rather than any single cause — produces the disease.
The most commonly identified contributors are:
- Long-term steroid (glucocorticoid) use — used to treat a wide range of illnesses, steroids can hinder blood flow to the femoral head in certain individuals, leading to bone deterioration.
- Excessive alcohol consumption — thought to alter stress levels, increase fat, and slow blood flow.
- Smoking.
- Osteoporosis — reduced bone density over time can exacerbate the impact of AVN.
AVN can affect both adults and children, and may also be brought on by certain other drugs, illnesses, or circumstances.
Why Hip Replacement is the Definitive Treatment
According to Dr. Ashwani Maichand, hip replacement is the definitive treatment for AVN, especially in advanced stages. There is no scientific evidence supporting the cure of AVN through medications or alternative therapies such as Ayurveda or homeopathy — many young patients lose valuable time and money pursuing stem cells, drilling, or other unproven options. Surgical intervention remains the most effective treatment.
Modern hip replacement aims to restore mobility, alleviate pain, and significantly improve the patient’s quality of life. It is especially beneficial for younger patients who wish to maintain an active lifestyle. Available techniques include:
- Bikini Incision hip replacement — the preferred MIS approach at Minomax Orthopaedics for AVN cases.
- MIS hip replacement — the broader minimally invasive principle.
- Direct Anterior Approach (DAA)
- SuperPATH
- Robotic-assisted hip replacement
How Hip Replacement is Performed
Hip replacement surgery for AVN involves replacing the damaged hip joint with a prosthetic implant. At Minomax Orthopaedics, Dr. Ashwani Maichand employs the MIS (Minimally Invasive Surgery) technique using a Bikini Incision approach, which minimises tissue damage and promotes faster recovery. The procedure may involve non-cemented implants, which are designed to integrate with the bone naturally.
Recovery and What to Expect
Post-surgery, patients can expect significant improvements in mobility and a marked reduction in pain. Initial recovery allows for independent movement — such as walking and climbing stairs — within a few days. Full recovery and a return to normal activities, including driving and light exercises, can be anticipated over several months.
Why Choose Minomax Orthopaedics
At Minomax Orthopaedics, Dr. Ashwani Maichand specialises in using advanced surgical techniques like the MIS approach for hip replacement, ensuring minimal recovery time and optimal outcomes for patients with AVN.
