EXISTENCE AND INCIDENCE OF OSTEOID IN OSTEOARTHRITIC FEMORAL HEADS

Abstract
1. Specimens are described in which osteoid was seen in undecalcified bone sections prepared from a number of osteoarthritic femoral heads. 2. It was localised mostly in the pressure segments. 3. The reason for the presence of this osteoid is not well understood and the possibilities of local histochemical changes and/or cellular metaplasia are discussed.
