Self-help group list-serv, designed to be an open forum for those having experience with the chronic disorder of osteonecrosis, also known as avascular necrosis (AVN or ON). This is a primary or secondary disease that can result from a variety of things, from "the bends" (scuba diving variety), to corticosteroid usage, lipid storage diseases, pregnancy, alcohol consumption, post fracture or trauma to a bone, sickle cell disease, among other causes. All are welcome to join in and share their success and frustrations in getting to diagnosis and treatment. Members are encouraged to share discussion on how to cope with change in life given an ON diagnosis. This entails both acute and chronic phases of the ON disease. THIS IS A MODERATED GROUP.

No solicitation of any kind can be submitted for posting. Please refrain from using long signature blocks (i.e. blog links [no more then 1 please], academic credentials, work place, social network links, etc).
