Study Groups: Where Information and Networking Mix
ACR study groups provide an excellent forum for networking at the ACR/ARHP Annual Scientific Meeting and are among the most highly sought-after sessions each year. Although study groups are not eligible for CME credits, they provide an opportunity for the exchange of new ideas and in-depth presentations of information. These groups give attendees the opportunity to discuss cases and share experiences with colleagues who share a common interest in one disease, a group of related disorders, or a specialized field of study.
Osteonecrosis
Osteonecrosis, also called avascular necrosis or aseptic necrosis, is a condition in which the death of bone cells (due to decreased blood flow) can lead to pain and collapse of areas of bone. This collapse of bone, in turn, can lead to degenerative arthritis of nearby joints, most commonly the hips and knees. Less frequently affected are the shoulders, hands, and feet. In rare instances, osteonecrosis can occur in the jaw— resulting in pain and mouth ulceration. Osteonecrosis is not fatal, but can lead to pain, arthritis, problems with physical activity, and even the need for joint replacement. Most of the 10,000 to 20,000 Americans developing osteonecrosis annually are between age 20 and 50. These individuals usually have a history of serious trauma, corticosteroid use, excess alcohol intake, or other conditions including systemic lupus erythematosus, dysbarism (“the bends” that occur with scuba diving), blood disorders, HIV infection, and radiation therapy.

Joint Surgery
Modern joint replacement surgery involves removal of worn cartilage from both sides of the joint, followed by resurfacing of the joint with a metal and plastic replacement implant that looks and functions much like a normal joint. Although nearly every joint in the body can be replaced, most replacement surgeries involve the hip or knee. Joint replacement surgery is typically recommended for patients who have tried non-surgical treatment but still have joint pain. While this is an extremely effective surgical treatment, total joint replacement should be considered as the last (rather than the first) treatment option for patients with advanced arthritis of the hip, knee, or shoulder.
