Summary
Histomorphometric analysis of bone biopsy specimens in humans is a reliable techniqu
e which provides information on bone status and turnover. A techniqu e of sternal
biopsy has been recently developed in “standin g horses” . The purpose of the present
study was to demonstrate that the histomorphometric analysis of sternal cancellous
bone was representative of other skeletal sites in horses.
Post-mortem cancellous bone samples were obtained from the sternum, 12th rib, ilium,
1st lumbar vertebra and the tibia, of seven adult horses and embedded in methylmethacrylate.
Sections, 7 μm thick, were cut and were stained with Goldner’s green trichrome. Histomorphometric
parameters were measured by a semi-automated method. Sections from the sternum were
qualitativel y similar to those from the rib, ilium and vertebra. Histomorphometric
measurements were easily performed on the sternal, ilium, rib and vertebral sections.
The tibial sections were not suitable for evaluation. The sternal histomorphometric
parameters of bone formation and resorption were overall representative of those from
other skeletal sites.
The present study demonstrated that sternal cancellous bone is acceptable for bone
histomorphometry in horses as it reflects overall skeletal osseous activity.
This study compares qualitatively and quantitatively cancellous bone from the sternum,
12th rib, ilium, first lumbar vertebra and the tibia of seven adult horses. Sternal
cancellous bone is acceptable for bone histomorphometry and reflects overall skeletal
osseous activity.
