Abstract

|
Avascular necrosis of the talus has frequently been reported following trauma because talus has no muscle insertions, sixty percent of the surface of the talus is covered by hyaline cartilage, takes only a small area for entrance of a blood supply. Osteonecrosis is also associated with a variety of nontraumatic disorders. There are many indications for steroid usage, patient with rheumatoid arthritis, systemic lupus erythematosus, chronic obstructive pulmonary disease, and status-post renal or cardiac transplantation may be on long-term steroid usage. Osteonerosis may develop. Avascular necrosis of the talus secondary to chronic steroid usage is an unusual case. Delay in detection of osteoncerosis may lead to fragmentation and collapse of the talar body. When pain on range of motion is present and conservative treatment have been exhausted, surgical treatment is indicated, that is, fusion of the ankle joint. However it is important that conservative treatment may prevent its various sequelae with early diagnosis because steroid-treated patients have a more operative risk and increased risk for postoperative infection. We report a rare case of corticosteroid induced avascular necrosis of talus after cardiac transplantation.
