A. Radiographic changes of spine after the TPU-A implantation: (a) X-ray images and (b) measurements of DHI% changes. B. (a) MRI images and (b) IDD grading score (modified pfirrmann grading) at different time points after surgery. C. (a) 3D reconstructions of μCT scans of the rabbit lumbar spines and the representative cross-sections 8 weeks after implantation, (b) Quantification of osteophyte bone volumes after different treatment. Error bars represent S.D., and significant differences were assessed with Student's t-test; *P < 0.05, **P < 0.01.
