FIG. 3.

Anteroposterior micro-computed tomography (μCT) image assessment for bone bridging in the neutral position. Representative coronal μCT images of L4 and L5 vertebrae and transverse processes from a Sham animal (A) and Isograft animals with bilateral bone bridging (B), unilateral bone bridging (Isograft#01, C), and no bone bridging (Isograft#03, D). Thick arrows show continuous bone bridging and thin arrows indicate the presence of a gap in the fusion mass. Scale bar=1 mm. Color images available online at www.liebertpub.com/tec
