title: Physical and chemical investigation of free bodies in articular osteochondromatosis.
abstract: Physical and chemical analysis of the newly formed calcified bodies in articular osteochondromatosis was carried out. X-ray diffraction showed that these bodies consisted of carbonate apatite from the group Francolite-Dahllite. Infrared spectroscopy, and chemical and differential thermal investigations supported the data gained from the X-ray diffraction analysis.
