Thirty-two femoral heads from autopsy material with arthrotic changes and 12 surgical specimens of femoral heads with different diseases have been examined with respect to their ability to form a 'double contour'. An additional bony plate within the cartilage, giving rise to the double contour, occurred only in the non-pressure zone of the articular cartilage. There were no major differences between autopsy and surgical material and these changes could also not be found in normal femoral heads. The origin of a double contour could be traced to tissue elements penetrating the subchondral bone from the bone marrow, and was the result of a gradual transformation with chondroid tissue as the starting material. We observed a similar transformation leading to lamellar bone in association with pannus.
对32个有关节病变的尸检股骨头材料以及12个患有不同疾病的手术切除股骨头标本进行了检查，以研究它们形成“双轮廓”的能力。软骨内额外的骨板形成双轮廓，仅出现在关节软骨的非压力区。尸检材料和手术材料之间没有重大差异，正常股骨头中也未发现这些变化。双轮廓的起源可追溯到从骨髓穿透软骨下骨的组织成分，是以软骨样组织为起始材料逐渐转化的结果。我们观察到与血管翳相关的导致板层骨形成的类似转化。
