Avascular necrosis can be particularly concerning because it may affect the hip before a patient expects to develop serious joint disease. The condition occurs when the blood supply to an area of bone is compromised, potentially leading to weakening and eventual collapse of the femoral head.
In selected early-stage cases, Core Decompression Surgery may be considered as a joint-preserving treatment.
For patients in Rohini Sector 11, Delhi, early diagnosis can be important because treatment options may change significantly once structural collapse progresses.
What Happens in Avascular Necrosis?
The upper end of the thigh bone forms the ball of the hip joint. If blood flow to part of this bone becomes inadequate, bone tissue can become damaged.
The condition is also known as osteonecrosis.
Possible risk factors can include previous trauma, prolonged or substantial corticosteroid exposure and certain medical conditions, although an obvious cause is not always identified.
Symptoms may begin as discomfort in the groin, thigh or buttock.
Pain may initially occur with weight bearing and become more persistent as the condition progresses.
Why Stage Matters
Early avascular necrosis may not be obvious on a standard X-ray.
MRI can be particularly useful when the condition is suspected but early structural changes are not clearly visible on radiographs.
As disease progresses, the femoral head may lose its normal shape. Once significant collapse and secondary arthritis have developed, joint-preserving procedures may become less suitable.
This makes staging an important part of treatment planning.
What Is Core Decompression?
During Core Decompression Surgery, one or more channels are created within the affected bone with the aim of reducing pressure and supporting the biological environment of the area.
Different surgical strategies may be used in selected circumstances.
The procedure is not appropriate for every stage of avascular necrosis, and it does not guarantee that future hip replacement will never be necessary.
Its potential role is greatest in appropriately selected patients before advanced collapse.
How Is Suitability Determined?
An orthopaedic surgeon may consider:
- Stage of avascular necrosis
- Size and location of the affected area
- Degree of femoral-head collapse
- Patient age
- Symptoms
- Function
- Condition of the joint surface
- Underlying risk factors
The decision requires more than confirming AVN on an MRI report.
What Happens After Surgery?
Postoperative weight-bearing restrictions may be recommended while the hip recovers.
Follow-up assessment helps monitor symptoms and structural progression. Rehabilitation may then be adjusted according to the procedure and individual recovery.
At UR Orthopaedic Clinic, patients with hip pain or a diagnosis of avascular necrosis can have their imaging and clinical findings reviewed. For patients from Rohini Sector 11, such evaluation can help clarify the stage of disease and whether joint-preserving management deserves consideration.
Patients diagnosed with AVN should avoid assuming that hip replacement is immediately inevitable. At the same time, delaying assessment until substantial collapse has occurred may narrow the available treatment options.
The most useful next step is accurate staging followed by a discussion of conservative management, joint-preservation procedures and replacement options where clinically appropriate.
