Bilateral osteochondritis dissecans of the carpal scaphoid. A radiological and anatomical study of one case.
The results of an anatomical and radiological study of one unusual case of bilateral osteochondritis dissecans of the carpal scaphoid are reported. On both sides, histological examination of the excised surgical specimen showed previous remodelling of the bone and marrow which had been followed by further aseptic necrosis. On the painful left side the sequestrum itself was fractured and appeared to be involved in a localised cystic remodelling reaction. The observations are discussed as an example of the histological changes in aseptic bone necrosis as well as an unusual type of pathology affecting the carpal scaphoid.
