Article Title: A 3D-printed load sharing implant achieved union of a 9-cm femoral segmental bone defect within three months using a hybrid Masquelet induction membrane technique. A case-report

Figure Lengend Snippet: A. The 3D-printed load sharing implant to cover a 9-cm femoral bone defect. The 3D-printed custom-made load cage was manufactured by Implantcast® GmbH as a load sharing bone scaffold and a bone graft container. The new manufacturing method of EBM® (Electron Beam Melting) is a process invested and used by Implantcast GmbH which offers a rapid, flexible and cost-effective implant directly from patients' 3D electronic data. Τhe 3D-printed cage is an EPORE® (EPORE® isa registered trademark of Implantcast GmbH) highly porous structure made of titanium alloy (Ti6AlV4). Titanium alloy is an excellent material for use as a porous ingrowth structure as it is biologically inert, ductile, corrosion resistant and has a high fatigue strength. Implantcast GmbH EPORE® design is characterized by high porosity and a low modulus of elasticity, supporting biological ingrowth. The EPORE® structure is specified by rods of 330–390 μm thickness which are arrayed in a way that mimics cancellous bone structures. B. The micro-architecture of the 3D-printed implant. The image shows the EPORE® 3D-printed implant (solid material in double helix form) from above and inside, appropriate for bone ingrowth and fluid exchange. EPORE® is designed to match natural cancellous bone structure that improves the osseous- integration process of the new prosthesis.
