Abstract

MENA, Karen et al. Do not let the Bone Die: Interiorizing with the avascular Bone Processes. Rev. argent. radiol. [online]. 2020, vol.84, n.3, pp.93-106. ISSN 1852-9992.  http://dx.doi.org/10.1055/s-0040-1716383.

The aim of this article is to review the locations, causes and specific radiological findings of avascular bone processes. Bone ischemia is defined as the alterations caused by irrigation deficit, leading into the bone destruction. However, there are differences between ischemic necrosis and bone infarction, based on the bone site of involvement. The most frequent etiology is traumatic and is usually unilateral. The most frequent sites of presentation are: femoral and humeral head, knee, and lunate. Magnetic resonance imaging (MRI) is considered the most sensitive and specific imaging modality for early diagnosis, staging and control. The knowledge of the causes, radiological findings and their different phases avoid the erroneous diagnosis of other lesions, such as primary or infectious, facilitating a correct therapeutic algorithm.

Keywords : osteonecrosis; bone disease; femur head necrosis.
