Micro-CT evaluation of interbody fusion at 4 and 8 weeks postoperatively. (a) Representative µCT images of the L4–L5 segment, including sagittal CT slices, 3D reconstructed coronal views, 3D reconstructions of the cage region (gray indicates the PTa cage), and binarized images illustrating bone ingrowth within the cage. (b) Quantitative analysis of trabecular bone microarchitectural parameters, including BV/TV, BS/TV, Tb.Th, Tb.N, Tb.Sp, and BMD, in each group at 4 and 8 weeks postoperatively. (n = 6; data are presented as mean ± standard deviation. Intergroup comparisons (PTa vs. CGF-PTa) and intragroup comparisons between different time points (4 W vs. 8 W) were both analyzed using independent-samples t-tests, as all data were normally distributed and based on independent samples. p < 0.05 was considered statistically significant.* indicates intergroup comparisons: *p < 0.05, **p < 0.01, ***p < 0.001; # indicates intragroup comparisons between time points: #p < 0.05, ##p < 0.01, ###p < 0.001).
