Condition Overview

AVN Shoulder:
What Avascular Necrosis Means and How Physiotherapy Helps at Every Stage

Avascular necrosis (AVN) of the humeral head — also called osteonecrosis — is a condition in which the bone tissue forming the ball of the shoulder joint loses its blood supply and progressively dies. As the bone cells die and the structural integrity of the humeral head deteriorates, the bone becomes increasingly vulnerable to collapse under normal joint loading — leading to deformity of the joint surface, damage to the overlying articular cartilage, and eventually severe shoulder dysfunction if the condition progresses unchecked.

AVN shoulder is not a rare condition in India. The most common cause in the Indian population is prolonged or high-dose corticosteroid use — prescribed for tuberculosis, autoimmune diseases, nephrotic syndrome, rheumatoid arthritis, asthma, and various other conditions. Steroids disrupt fat metabolism within bone, causing fat emboli that block the small arteries supplying the humeral head, leading to ischaemia and bone death. Other significant causes include excessive alcohol consumption, sickle cell disease, previous shoulder fracture or dislocation that disrupted the humeral head blood supply, decompression sickness, and certain chemotherapy agents. Patients from across Noida and Greater Noida West — where the prevalence of steroid-managed conditions is significant — form a notable proportion of AVN shoulder presentations at our clinic.

AVN shoulder passes through progressive radiological stages, from early marrow oedema detectable only on MRI, through subchondral bone changes and the characteristic "crescent sign" of early collapse, to advanced humeral head deformity and joint surface destruction. The stage at which the condition is diagnosed and management begins is the most important determinant of outcome. Early-stage AVN managed conservatively with structured physiotherapy — combined with addressing the underlying cause — can preserve shoulder function and delay or prevent humeral head collapse for years. Advanced-stage AVN with significant structural compromise typically requires surgical intervention, followed by structured post-operative physiotherapy rehabilitation.

At 360 Neck Shoulder Advanced Rehabilitation Centre, Sector 73 Noida — serving patients from Noida and Greater Noida West — our AVN shoulder protocol is stage-specific and medically coordinated: precisely calibrated to what is appropriate and protective at the patient's current AVN stage, and always aligned with the orthopaedic and medical teams managing the underlying condition.

Causes & Risk Factors

What Causes AVN Shoulder:
Steroids, Alcohol, Fracture, and Why India Has High Prevalence

Understanding the cause of AVN shoulder in each individual patient matters because addressing or modifying that cause is as important as the rehabilitation itself.

  • Corticosteroid Use — The Most Common Cause in India: Prolonged or high-dose steroid use — whether for tuberculosis treatment, autoimmune disease management, or other medical conditions — disrupts the normal fat metabolism within bone marrow, producing fat microemboli that occlude the small arteries supplying the humeral head. The risk is dose-dependent and duration-dependent, and is significantly higher with oral than with inhaled or topical steroids. Any patient receiving long-term steroid treatment who develops shoulder pain should be assessed promptly for AVN. Patients from across Noida, Greater Noida West, and broader NCR with steroid-managed conditions are particularly advised to seek early assessment at our physiotherapy clinic in Sector 73.
  • Excessive Alcohol Consumption: Alcohol-induced AVN is the second most common cause, operating through a similar fat metabolism disruption mechanism to steroids. The risk increases with cumulative alcohol intake over years. Reducing or eliminating alcohol consumption after an AVN diagnosis is a medically important component of conservative management alongside physiotherapy.
  • Previous Humeral Head Fracture or Shoulder Dislocation: Displaced fractures of the humeral head — particularly those involving the anatomical neck — and severe shoulder dislocations can directly disrupt the terminal branches of the anterior humeral circumflex artery that supply the humeral head, producing post-traumatic AVN. This form of AVN typically presents weeks to months after the original injury, when the expected recovery plateau is not reached or when previously improving pain begins to worsen.
  • Sickle Cell Disease and Haematological Conditions: Sickle cell disease causes vaso-occlusion in the small vessels supplying bone, producing AVN across multiple sites — the humeral head, femoral head, and distal femur are most commonly affected. AVN management in sickle cell patients requires close coordination with haematology to manage the underlying haematological condition alongside shoulder rehabilitation.

TECAR Periarticular Therapy — Soft Tissue Support for AVN Shoulder

In AVN shoulder, TECAR therapy is applied to the periarticular soft tissues — the rotator cuff, surrounding capsule, and shoulder girdle musculature — rather than to the avascular bone itself. Reducing periarticular inflammation, maintaining rotator cuff health, and preserving the muscle support system around a structurally compromised humeral head significantly reduces the functional impact of the bone pathology and protects the joint from the compressive overloading that accelerates humeral head collapse.

Our Protect–Preserve–Prepare
Stage-Matched AVN Shoulder Physiotherapy Protocol

AVN shoulder physiotherapy at 360 Neck Shoulder — serving patients from Noida and Greater Noida West at Sector 73 — is always matched precisely to the current AVN stage and coordinated with the patient's orthopaedic and medical management teams.

Stage 1 — Protect: Early AVN Conservative Management (Stages 1–2)

In early AVN where humeral head structural integrity is maintained, the physiotherapy priority is protecting the vulnerable bone from compressive overload while maintaining full shoulder function. Joint offloading education — guiding which activities and positions increase humeral head compression and must be avoided or modified — is central. Gentle, non-compressive range of motion exercises maintain full shoulder mobility. Progressive shoulder girdle strengthening — particularly the rotator cuff and scapular stabilizers — builds the muscular support system that distributes joint loading and reduces the direct compressive burden on the avascular humeral head. TECAR therapy maintains the health of the periarticular soft tissues and reduces the secondary inflammation that compounds pain in the arthritic environment around the necrotic bone. Most patients from our physiotherapy clinic in Noida maintain excellent functional shoulder use for significantly longer than without structured rehabilitation.

Stage 2 — Preserve: Functional Optimisation During Structural Progression (Stages 2–3)

As AVN progresses to early subchondral collapse, the rehabilitation focus shifts to maximising and preserving functional shoulder capacity for as long as possible. Movement rehabilitation keeps the shoulder as mobile as possible despite increasing structural compromise. Strengthening maintains the muscular support that protects the collapsing joint surface. Pain management — through TECAR periarticular therapy, activity modification, and analgesic guidance in coordination with the treating physician — keeps the patient as functional and active as possible. Close monitoring of symptoms and regular orthopaedic imaging review determines when conservative management remains appropriate and when surgical discussion should begin. Our physiotherapists at 360 Neck Shoulder Noida maintain communication with the patient's orthopaedic team throughout this phase.

Stage 3 — Prepare and Rehabilitate: Pre- and Post-Surgical Management (Stages 3–5)

For patients progressing to surgical management — core decompression in earlier stages or total shoulder arthroplasty in advanced collapse — physiotherapy plays a dual role. Pre-surgical physiotherapy ("prehabilitation") maximises the shoulder's muscular support and range of motion before surgery, directly improving post-surgical outcomes. Post-surgical rehabilitation follows the specific surgical protocol — progressively restoring range of motion, rebuilding rotator cuff and scapular strength, and advancing to full functional recovery. For patients from Greater Noida West, Gaur City, Noida Extension, and Crossings Republik who have undergone shoulder replacement for AVN at hospitals across NCR, we provide comprehensive post-operative rehabilitation coordinated with their surgical team.

Patient Questions

Frequently Asked
Questions on AVN Shoulder

AVN shoulder is death of bone tissue in the humeral head due to disrupted blood supply, leading to progressive bone weakness and collapse. The most common cause in India is prolonged corticosteroid use — for tuberculosis, autoimmune diseases, and nephrotic syndrome. Other causes include excessive alcohol, previous shoulder fracture or dislocation, sickle cell disease, and certain chemotherapy agents. Any patient on long-term steroids who develops shoulder pain should seek physiotherapy assessment at 360 Neck Shoulder Noida promptly to rule out early AVN.
Stage 1 (MRI changes only): physiotherapy maintains mobility and builds muscular support to protect the bone. Stage 2 (X-ray sclerosis): same approach with greater emphasis on joint offloading. Stage 3 (crescent sign — early collapse): physiotherapy continues with orthopaedic monitoring. Stages 4–5 (progressive collapse): physiotherapy optimises function before surgery and provides comprehensive post-surgical rehabilitation at 360 Neck Shoulder Noida. The earlier physiotherapy begins, the more function is preserved.
Early-stage AVN (Stages 1–2) can be effectively managed without surgery through structured physiotherapy, addressing the underlying cause, and protecting the humeral head from compressive overload. The goal is to preserve shoulder function and delay or prevent collapse for as long as possible. Advanced-stage AVN with significant humeral head collapse typically requires surgical management — core decompression or shoulder replacement — followed by structured physiotherapy rehabilitation at our Noida clinic.
Corticosteroids are widely used in India for tuberculosis, autoimmune diseases, nephrotic syndrome, and other conditions — and in some communities are taken without medical supervision. Prolonged or high-dose steroid use disrupts fat metabolism in bone, producing fat emboli that block the arteries supplying the humeral head. India's high burden of TB and autoimmune conditions makes steroid-induced AVN significantly more prevalent than in many other countries. Patients on prolonged steroid treatment across Noida and Greater Noida West should seek prompt assessment if shoulder pain develops.
Activities placing high compressive or impact loads through the humeral head should be avoided or modified — particularly heavy overhead lifting, contact sports, and activities involving fall risk to the shoulder. Specific restrictions depend on your AVN stage and degree of structural compromise on imaging. Your physiotherapist at 360 Neck Shoulder Noida will provide precise activity modification guidance based on your current stage, keeping you as active as possible while protecting the compromised humeral head.
For early-stage AVN managed conservatively, physiotherapy in Noida is typically ongoing — with intensive phases of three to six months followed by maintenance programmes as long as conservative management remains appropriate. Post-surgical rehabilitation after shoulder arthroplasty typically involves four to six months of structured physiotherapy. Our physiotherapists at 360 Neck Shoulder Noida coordinate with the patient's orthopaedic and medical teams throughout — serving patients from Noida and Greater Noida West at every stage.
