Explanation of 3D morphometric parameters analyzed within two volumes of interest (VOI): the cartilage and cortical region and the trabecular region.

Bone mineral density (g/cm3) BMD Volumetric density of bone within a mixed bone-soft tissue VOI
Percent bone volume (%) BV/TV Proportion of VOI occupied by binarised solid objects (e.g., bone)
Intersection surface (mm2) i.S. Surface of VOI intersected by bone, useful for evaluating bone growth at a defined boundary
Bone specific surface (mm−1) BS/BV Ratio of bone surface to bone volume within the VOI, useful for characterizing the relative complexity of structures
Object number Obj.N. Total number of discreet binarised objects within the VOI, where a discreet object is a connected cluster of solid (white) voxels fully surrounded by space (black) voxels
