Multifocal osteonecrosis in a patient with anamnestic ulcerative colitis. Is there a relationship with the disease and the use of glucocorticoids twenty years before? A brief review of the literature.

In 2013 a 40 year old man came to visit in our Rheumatology Unit because of a recent bilateral shoulder and hip pain. He had been treated from 1990 to 2000 with Cyclosporin A and Sulfasalazyn because of an ulcerative colitis which was completely in remission from 2000 . Glucocorticoids at the mean daily dose of 50 mg were administered only in the first period (1990-92). X-plain rays showed a suspicious multifocal osteonecrosis of both femoral and humeral heads. Magnetic Resonance confirmed the diagnosis (stage III and IV following Ficat and Arlet's criteria). The patient was treated with a cycle of hyperbaric oxygen therapy, with two cycles of intravenous clodronate and with a 2-month cycle of teriparatide. The treatment was able to save a sufficient function for both shoulders, while for both hips arthroplasty the surgery was required. The risks of osteonecrosis linked to inflammatory bowel diseases or to its therapy are discussed.
