Table 2.

Three-point-bending stiffness and elastic modulus of rabbit radii after 5, 10, and 15 weeks of surgery to repair a 10 mm defect using poly (octanediol citrate) click – hydroxyapatite (POC-Click-HA) single phase scaffolds, POC-Click-HA biphasic scaffolds, negative control (empty defect), and autologous bone. The results are expressed as the mean ± SD.
