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]

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]
