From: In vivo evaluation of porous nanohydroxyapatite/polyamide 66 struts in a goat cervical fusion model
Lateral view scans of the goat C3/C4 motion segment in each group with the different implants. (Aa) The porous strut group at 12 weeks post-implantation; (Ab) The dense strut group at 12 weeks post-implantation; (Ba) The porous strut group at 24 weeks; (Bb) The dense strut group at 24 weeks. A radiolucent gap was observed at the conjunction site (red arrows).
