52) Although the reasons for AGF failure are not entirely clear, possible theories for decreased efficacy include; poor concentrating techniques; platelet clumping; platelet gel fibrinolysis; and an inadequate platelet gel carrier for posterolateral arthrodesis
Pedicle screws and rods from T12 to L2 were placed, and posterior and posterolateral arthrodesis
from T12 to L2 was achieved using morcellized cortical cancellous bone, which was locally harvested autograft, and allograft bone.
Reduction was completed by means of pedicle instrumentation and posterolateral arthrodesis
from L2 to L5.
