He winces with compression of his pelvis. Current imaging is shown in Figures A and B. The concept of steroid arthropathy is largely based on studies in subprimate animal models, and it is an unusual occurrence in humans if the number of injections is limited to three to four per year in weight-bearing joints. Family physicians wanting to perform arthrocentesis on deep joints, such as the hip or vertebral joints, should obtain extensive training in these higher risk procedures.
