Abstract

Whole segments of canine femoral shaft, each containing two porous coated, rod-like titanium implants, were evaluated for the effects of micromotion on bony ingrowth. The specimens were processed for nondecalcified histologic study. Precise cross-section orientation of the cortico-implant surface had to be established and maintained throughout the sectioning process. This paper reports on an embedding system that meets the intended goals by utilizing a modified Spurr embedding medium polymerized in custom-made Plexiglas molds. Thepolymerlmold compositeis sectioned as aunit andground to the desired thickness for histologic evaluation. (The J Histotechnol 16:145, 1993)
