The evaluation of bioceramics and vascularized fibula.
A: SPECT (Coronal position) showed the fibula flaps were survived.
B: CT (Axial position), the orange arrow orange indicated the vascularized fibula; the green arrow indicated the β-TCP bioceramic granules.
C: SPECT/CT (Axial position), showing high metabolic activities in the vascularized fibula and the surrounding β-TCP bioceramic granucles.
D: X-ray: one week after operation, the initial position of the vascularized fibula (the blue arrow), bioceramic granules (the red arrow) and allograft fibula (the yellow arrow).
E: X-ray: 21 months after operation, ‘umbrella like’ bone formation was observed at the end of the vascularized fibula (the blue arrow); bioceramic granules were degraded for new bone formation (red arrow); the allograft fibula and the remaining bone were linked together (red arrow).
