A bone biopsy arrangement especially suited for use in obtaining axial skeleton trephine samples from the spinal vertebra centrum of a living test specimen in a safe and rapid manner. The disclosed arrangement uses radiographic mapping, precise mechanical control of the trephine with an apparatus disclosed in detail, conventional trephine energizing and a test speciment such as a rhesus monkey. Improved quality plural samples from a single test subject that were heretofore considered too inaccessible and dangerous for practicality are achieved.

An axial skeleton bone remodeling study method comprising the steps of: mapping radiographically the spinal lumbar vertebral region of a living test subject using a plurality of angularly segregated radial radiographic views; computing from said mapping the trigonometric accessing dimensions of a spinal process free spinal centrum diagonal path radial of a selected vertebra centrum within said lumbar region; extracting from said process free centrum diagonal path a first mechanically guided full transverse trephine sample; subjecting said test subject to a determined regimen of bone structure influencing test environment; excising from a second process free spinal vertebra centrum diagonal path a second mechanically guided full transverse trephine sample; and comparing said first and second full transverse trephine samples.
