About
The aim of this study was to investigate the simply use of three-dimensional (3D) printed individualized porous implants in the absence of autogenous/allogeneic bone graft or any osteoinductive agents to treat the large bone defects caused by varies of pathogenesis and systematically study its long-term therapeutic effect and osseointegration characteristics.
Full description
A selection of fifty-eight patients with large bone defects caused by tumor, infection or trauma received the individualized porous implants treatment, and two typical cases were chosen for detailed study. Further, the large segmental femur defect model of sheep was utilized to study the osseointegration characteristics of the individualized porous implants in 1, 3, 6 months after implantation.
