Three dimensional modeling and analysis of Haversian systems in compact bone tissue

Abstract

This study provides a qualitative as well as quantitative characterization of the geometry and architecture of the Haversian systems at a microscopic level. A procedure was developed and employed to generate a three dimensional computer model from serial sections of equine bone. From the reconstruction, quantitative calculations were made. including porosity. surface areas. cross sectional areas, anci cross sectional shapes. Also the porosity due to Volkmann canals was estimated. Other more qualitative calculations included the nature of branching. termination. taper'n-and-general osteon movement. Any chance in the specimen size or shape during, the entire processing-was carefully documented and corrected for where possible. One of the goals of the research was to assess and evaluate the procedures developed and identify ways to further improve accuracy. With a computerized three dimensional imag-e of the bone microstructure. detailed calculations can be made and insig-ht cained more accurately than with two dimensional models or past three dimensional models.
