The osteonecrosis was idiopathic in 6 shoulders, was a result of corticotherapy in 10, occurred after radiation in 2, and occurred after Gaucher's disease in 1. A total shoulder arthroplasty was performed in 5 cases and a hemiarthroplasty in 14. [ncbi.nlm.nih.gov]

’s disease, alcoholism Pathophysiology: initially necrosis of epiphysis, with variable necrosis of adjacent cartilage; dead bone is resorped by “creeping substitution” over months/years; new bone is soft, may flatten and cause degenerative joint disease [pathologyoutlines.com]

The radiographic appearance is that of a soft tissue mass associated with bone destruction at a site of previous bone infarction. [emedicine.medscape.com]

Patients with AVN, when compared with controls, had a significantly higher incidence of neurological disease (39% vs 14%; P 0.001) and Cushingoid body habitus after steroid treatment (79% vs 53%; P 0.004). [ncbi.nlm.nih.gov]

Oral ulcer, pleuritis, Raynaud's phenomenon, cutaneous vasculitis, lymphadenopathy, autoimmune thyroiditis, peripheral neuropathy and Sjögren's syndrome were higher incidence in SLE patients with AVN. [ncbi.nlm.nih.gov]

Necrotic area in cross section is yellow, opaque, chalky with hyperemic fibrous tissue at margin Adjacent bone may be thickened Late changes are breaks in smooth contour of femoral head, destruction of articular cartilage, loose bodies and marginal osteophytes [pathologyoutlines.com]

In stage IV there is progressive loss of articular cartilage and the development of acetabular osteophytes. The radiographic picture is that of osteoarthritis superimposed on a deformed femoral head. [doi.org]

Unlike other bone disorders, this happens most often in men between age 40 and 50. Untreated injuries and diseases can cause AVN. Other causes include: Injury, such as a major impact from an accident or during sports. [upmc.com]
