In 232 patients the osteonecrosis, referred to as "idiopathic,” had occurred in the absence of a subcapital fracture. The present paper describes the pathology of the necrotic lesions in these 232 patients. The use of undecalcified sections and microradiography provides evidence of bone marrow calcification which, at the margin of the lesion, is sufficient to influence the radiographic features of the lesion significantly. Although a subchondral fracture is an almost constant feature of osteonecrosis when it occurs in a femoral head with a normal articular cartilage, no such fracture was found in cases in which osteonecrosis had occurred in an osteoarthritic joint International Skeletal Society, 1992 Osteonecrosis nationallicence Bone infarct nationallicence Rheumatoid arthritis nationallicence Sissons Hubert Department of Pathology and Laboratory Medicine, Hospital for Joint Diseases Orthopaedic Institute, New York, USA aut Nuovo Margaret Department of Pathology and Laboratory Medicine, Hospital for Joint Diseases Orthopaedic Institute, New York, USA aut Steiner German Department of Pathology and Laboratory Medicine, Hospital for Joint Diseases Orthopaedic Institute, New York, USA aut Skeletal Radiology Springer-Verlag 21/4(1992-05-01), 229-238 0364-2348 21:4<229 1992 21 256 https://doi.org/10.1007/BF00243063 text/html Onlinezugriff via DOI 1 research-article jats NATIONALLICENCE 856 40 https://doi.org/10.1007/BF00243063 text/html Onlinezugriff via DOI NATIONALLICENCE 700 1- Sissons Hubert Department of Pathology and Laboratory Medicine, Hospital for Joint Diseases Orthopaedic Institute, New York, USA aut NATIONALLICENCE 700 1- Nuovo Margaret Department of Pathology and Laboratory Medicine, Hospital for Joint Diseases Orthopaedic Institute, New York, USA aut NATIONALLICENCE 700 1- Steiner German Department of Pathology and Laboratory Medicine, Hospital for Joint Diseases Orthopaedic Institute, New York, USA aut NATIONALLICENCE 773 0- Skeletal Radiology Springer-Verlag 21/4(1992-05-01), 229-238 0364-2348 21:4<229 1992 21 256 Metadata rights reserved Springer special CC-BY-NC licence nationallicence BK010053 XK010053 XK010000 NATIONALLICENCE NATIONALLICENCE NL-springer
