Long-term follow-up of the vascularized iliac bone graft

Abstract:
We retrospectively studied four patients who were treated with vascularized iliac bone graft for reconstruction of the tibia. The average length of the graft was 9.8 cm. The follow-up period was 11-18 years (average, 14.8 years). Although two of them were osteomyelitis, no recurrence occurred. We also studied four patients who were treated with nonvascularized iliac bone graft for anterior spinal interbody fusion (average, 10.8 years). Cosmetic problem slightly exists because the vascularized iliac bone still showed the original shape, which was prominent from the tibial contour. The vascularized iliac bone marrow showed iso intensity in both T1 and T2 image of the MRI. However, nonvascularized iliac bone graft on the spine showed high intensity in both T1 and T2 imaging. Since the vascularized iliac bone graft does not present fatty degeneration, it shows strong resistance against infection.
