A novel unidirectional porous β-tricalcium phosphate grafting for vertebralfracture in the elderly: preliminary case series

摘要

To treat vertebral fractures with posterior wall injury in theelderly, vertebral bone grafting is generally performed through a posterior transpedicularapproach, combined with pedicle screw fixation. An autologous bone is ideal to treat thisdisorder. However, harvesting autologous bones from the elderly with osteoporosis islimited by the amount and quality of available autologous bone. Thus, we developed abone-grafting substitute. The newly developed unidirectional porous β-tricalciumphosphate, with a porosity of 57% (UDPTCP; Affinos , Kuraray Co., Ltd., Tokyo,Japan), is used in the bone-grafting procedure. This is the first report of UDPTCP used asan artificial bone graft in patients with an acute vertebral burst fracture.
