Figure 2.. Representative femoral radiographs. From left, implanted with β-TCP with PLA-DX-PEG and rhBMP-2, β-TCP with PLA-DX-PEG without rhBMP-2, and critical size bone defect without implantation (sham surgery). Sequential radiographs show bone repair at 2, 4, and 8 weeks after implantation in the experimental group. Reproduced from Yoneda et al.47 with permission from Elsevier. DX: p-dioxanone; PEG: poly(ethylene glycol); PLA: poly(lactic acid); rhBMP-2: recombinant bone morphogenetic protein 2; β-TCP: β-tricalcium phosphate.
