What is avascular necrosis of the hip?
Avascular necrosis (AVN) — also called osteonecrosis — occurs when the blood supply to the head of the femur (the ball of the hip joint) is interrupted. Without adequate blood flow, bone cells begin to die. Over time, the weakened femoral head may collapse, destroying the hip joint surface.
AVN of the hip disproportionately affects people in their 20s, 30s and 40s — a much younger age group than typical hip arthritis. It is not wear-and-tear; it is a vascular problem, and identifying the cause matters for management.
India carries a disproportionate share of this disease. According to a 2022 comparative analysis in the Journal of Orthopaedics, avascular necrosis is the leading indication for total hip replacement in India — whereas in a US database of more than 225,000 hip replacements it ranked third, at about 6% of cases. US reviews estimate 20,000–30,000 new AVN cases each year there; India lacks a comparable registry, but the published comparison points to a heavier relative burden here.
Common causes
- Corticosteroid use — the most common non-traumatic cause. Prolonged or high-dose steroid use (for lupus, kidney transplant, inflammatory bowel disease, asthma or other conditions) significantly raises the risk of AVN.
- Alcohol — chronic heavy alcohol use is independently associated with AVN, likely through fat metabolism changes that affect small blood vessels in bone.
- Trauma — a hip fracture or dislocation can directly disrupt the vessels supplying the femoral head, causing post-traumatic AVN.
- Sickle cell disease — abnormally shaped red blood cells can block small vessels in the femoral head, leading to AVN. A meaningful proportion of patients with sickle cell disease develop hip AVN.
- Idiopathic — in some cases no clear cause is found. A thorough assessment is needed to rule out the above before concluding the cause is unknown.
Because AVN often strikes younger adults who are working, active and may not expect a hip problem, there is sometimes a delay in diagnosis — particularly when early symptoms are vague and an X-ray appears normal. This delay has consequences for treatment options (see below).
Staging matters — and why early MRI is critical
AVN of the hip is classified by stage, most commonly using the Ficat or ARCO classification. Stage determines which treatment options remain available — and waiting too long can close the window for joint preservation.
Ficat / ARCO stages at a glance
- Stage 1 — MRI shows early changes (bone marrow oedema, early necrotic lesion). The femoral head shape is normal. X-ray is typically normal at this stage.
- Stage 2 — MRI and sometimes X-ray show a sclerotic or cystic lesion in the femoral head, but the head remains round — no collapse yet. Joint-preserving intervention is still possible.
- Stage 3 — the femoral head begins to collapse (crescent sign on X-ray). The joint surface is compromised. Joint-preserving options become limited and replacement is more often considered.
- Stage 4 — the acetabulum (socket) is also affected. Secondary osteoarthritis has set in. Hip replacement is the typical recommendation at this stage.
Why X-ray misses early AVN
X-rays show bone changes only after significant structural loss has already occurred. In stages 1–2, the femoral head is still intact and X-ray appears normal — but MRI shows the lesion clearly. A patient who presents with groin pain and a normal X-ray should not automatically be reassured. If AVN is suspected — particularly with a history of steroid use, alcohol use, trauma, or sickle cell — an MRI of the hip is the appropriate investigation.
This matters because stage 1 and stage 2 AVN, caught early, may be managed with joint-preserving procedures. The same patient presenting at stage 3–4 with a collapsed femoral head has fewer options.
Treatment by stage — joint preservation vs hip replacement
Joint-preserving options
When the femoral head has not yet collapsed, the goal is to preserve the joint. Options that may be considered include:
- Joint-preserving approaches — early-stage AVN may be managed with joint-preserving approaches before femoral head collapse. The right option is decided after MRI staging and a clinical assessment of lesion size and location.
- Osteotomy — repositioning the femoral head so the necrotic zone is moved out of the load-bearing area. May be appropriate in selected younger patients with a favourable lesion location.
- Protected weight-bearing — reducing load on the hip while the bone is vulnerable. The role of this as a standalone measure is limited; it is usually part of a broader plan.
The suitability of each approach depends on the lesion size, location and overall stage. Not every early-stage case is a candidate for every procedure — a careful assessment is needed.
When hip replacement becomes necessary
Once significant collapse of the femoral head has occurred, the joint surface is permanently damaged and joint-preserving procedures are unlikely to restore meaningful function. At stages 3–4, total hip replacement (THR) is the typical recommendation.
- Removes the collapsed femoral head and lines the socket with an implant
- Replaces painful bone-on-bone contact with smooth implant surfaces
- Aims to restore pain-free walking and function
In younger patients undergoing THR for AVN, the longevity of the implant and the possibility of future revision surgery are discussed explicitly as part of the consent process. See also: Hip Replacement in Surat.
A common question from younger patients: "I'm 32 and I have AVN — do I need hip replacement?" The honest answer is: it depends entirely on the stage at diagnosis and the size and location of the lesion. An MRI, clinical assessment and a frank discussion of options is the starting point — not an assumption that replacement is inevitable.
Choosing a surgeon for AVN hip in Surat
AVN of the hip is not the same as routine hip arthritis. It is a vascular problem that often affects younger patients, and the treatment decision — whether to attempt joint preservation or proceed to replacement — requires familiarity with the full range of hip procedures, not just replacement.
Dr. Aman Khanna holds an M.S. in Orthopaedics from Government Medical College, Surat and has been in orthopaedic practice since 2016. His fellowship in Sports Medicine, Hip & Knee at Lyon Croix-Rousse University Hospital, France (2021) provided specific exposure to hip preservation and reconstruction techniques in a high-volume European centre. His IOA Clinical Fellowship in Arthroscopy (2024) further broadens the joint-level assessment he brings to complex hip cases. He is a member of ISAKOS and the Indian Orthopaedic Association.
When a patient presents with suspected AVN, the evaluation includes a full history (steroid use, alcohol, trauma, haematological conditions), appropriate imaging — including MRI if not already done — and staging before any treatment recommendation is made. Joint-preserving options are discussed where the stage permits them, not bypassed in favour of replacement.

Frequently asked questions — AVN of the hip in Surat
I'm in my 30s and was told I have AVN of the hip — do I definitely need hip replacement?
Not necessarily. Whether hip replacement is needed depends on the stage of AVN at the time of diagnosis. In early stages (Ficat/ARCO 1–2) before the femoral head has collapsed, joint-preserving options such as core decompression or osteotomy may be appropriate. Stages 3–4 with significant collapse are more likely to require replacement. An MRI and clinical assessment are needed to determine which stage applies and which options are realistic.
What causes avascular necrosis of the hip in young adults?
AVN of the hip in young adults is commonly linked to prolonged or high-dose corticosteroid use (for conditions such as lupus, kidney transplant, asthma or inflammatory disease), heavy alcohol use, trauma to the hip, and conditions such as sickle cell disease. In some cases no clear cause is identified. The underlying mechanism is disruption of the blood supply to the femoral head, leading to bone death and eventual collapse if untreated.
Why is MRI important for AVN of the hip — can't X-ray detect it?
X-rays are often normal in early AVN (Ficat/ARCO stages 1–2) because bone changes at that point are not visible on plain films. MRI can detect early AVN before any collapse occurs — which is clinically important, because early-stage AVN is when joint-preserving interventions are most likely to be beneficial. By the time X-ray changes are apparent, collapse may already be present.
What are the treatment options for AVN of the hip?
Early-stage AVN may be managed with joint-preserving approaches, while advanced stages usually need hip replacement — the right option is decided after MRI staging. The appropriate treatment depends on the stage of AVN, lesion size, and individual clinical factors assessed at consultation.

When does AVN of the hip require total hip replacement?
Hip replacement is typically considered when AVN has progressed to Ficat/ARCO stage 3 or 4 — meaning significant collapse of the femoral head has occurred and the joint surface is damaged. At this stage, joint-preserving procedures are unlikely to restore a functional joint. Replacement removes the collapsed femoral head and damaged socket and replaces them with an implant. The decision is made based on imaging, symptom severity and the patient's overall health and activity demands.
