Trabecular oedema

Trabecular oedema, also called trabecular edema or bone marrow edema, is the traditional name for interstitial fluid collecting in the trabecular bone marrow. The term was first used in 1988 for inflammatory changes in the marrow. Later studies suggested that inflammatory responses, not fluid influx, explain the finding, so it was renamed bone marrow lesion, although radiologists still use both terms interchangeably. It mostly affects the musculoskeletal system, commonly in the feet, ankles, knees and hips, with pain, joint swelling and limited joint function. Primary cases have no obvious cause and secondary cases follow another condition. Diagnosis rests on magnetic resonance imaging, and minor cases are treated with rest and anti-inflammatory drugs.
