肘関節軟骨の摩耗状態についての解剖学的研究

抄録

We dissected 88 elbow joints of human cadavers. The mean age of these cadavers was 68.5 years. The presence of degeneration of the articular cartilage, osteophyte or free body was observed macroscopically. At first stage, articular degeneration develops at the posterior part of the crest which separates the capitulum from the trochlea and the medial ridge of the radial head. Following this, the cartilage of the capitulum and center of the radius head is degenerated and finally, the cartilage of the trochlea and trochlea groove is degenerated.
These suggest that the humeroradial joint takes more mechanical stress than the humeroulnar joint.
