Representative renderings of μCT images. Autograft hip (a, left), allograft hip (b, center), and allograft femur (c, right) grafting groups. Bone formation in the intertransverse space was seen in each experimental group (yellow dashes surrounding only the newly formed bone located in the area between transverse processes). Although allograft hip (b) yielded higher fusion mass volumes, this difference was not statistically significant. Hip-derived fusions tended to appear as single intertransverse masses, while femoral allografts exhibited bone formation with a scattered pattern
