Introduction:The anterior column of the spine is often destroyed by trauma, infection or tumours. It is reconstructed by using an autograft, allograft or synthetic cages. The fibular autograft provides good strength, incorporates quickly and has less risk of disease transmission, which is a big advantage in communities with a high incidence of HIV.Various authors cite that its major drawback is the size of its footprint because of the possibility of subsidence. We could not, however, find any literature that measures its size.
