“…They concluded that best results are achieved in the group treated with anterior resection, debridement and fusion using autogenous bone grafts (Hong Kong procedure) [20,30]. Anterior debridement and arthrodesis allow reaching the focal point of the disease directly, effective debridement of the focal point, rapid bony union with the grafts and prevent progressive collapse and kyphosis [12,20,21,30,32]. However, it has been reported that such successful outcomes are not observed regarding progressive collapse and kyphosis, particularly in the case of two or more levels of involvement, risks of graft insufficiency and increased kyphotic deformity [1,3,9,11,15,23,25].…”
