Histomorphometric changes in the trabecular structure of the principal compressive stress region in the femur in @entity1 with @entity571 and @entity174 of the femoral neck are described. Femoral heads were obtained from @entity1 who had surgery for the treatment of @entity2249 or total hip replacement for advanced @entity571 . Blocks from the principal compressive region of a coronal slice were sampled systematically to prepare 10 microns sections for automated analysis. There was no significant difference in the mineral bone content of the osteoarthritic (OA) and @entity2249 ( @entity2249 ) cases or between males and females for each group. The regression of mineralized bone on age was significant for OA data, showing a decrease in mineralized bone volume with age, whereas there was no significant relationship for the @entity2249 data. Surface density was significantly lower in the OA group than in the @entity2249 group despite the fact there is no difference in the mineralized bone. The regression of surface density on age was not statistically significant in both groups, although regression of surface density on the mineralized bone was significant for both groups and demonstrated that OA cases generated less surface than @entity2249 cases for the same amount of mineralized bone volume. The trabeculae in OA were significantly thicker than in @entity2249 , and spacing in OA was significantly greater than in @entity2249 . The regression of trabecular thickness and spacing on age was not significant for either OA or @entity2249 . For OA, thickness and spacing showed a significant regression on the mineralized bone volume, positive and negative, respectively.(ABSTRACT TRUNCATED AT 250 WORDS)
