Micro-CT images. Micro-CT images of femoral segmental bone defects treated with BMP-2 gene activated muscle grafts (A – F) and autologous bone grafts (G – L) and longitudinal, medial sections of micro-CT images of femoral segmental bone defects treated with BMP-2 gene activated muscle grafts (M – R) and autologous bone grafts (S – X) 8 weeks after surgery. All images of the femora treated with BMP-2 gene activated muscle grafts (A – F and M – R) displayed complete bridging and regeneration of cortical bone and cancellous bone formation in the medullary cavity. The micro-CT-images of the autologous bone graft group (G – L and S – X) revealed incomplete bridging of several defects (U, V and W).
