Unfold new spaces for fusion
Inspired by human anatomy, empowered by science – our cages fuse technological advancements with clinical values. The result is a major leap in anterior and posterior stabilization.
Structan®
You think this is an ordinary cage lattice? Well, get impressed by the science behind Structan®. Decades of experience, combined with modern technology, have led to the creation of it – a structure designed for improved clinical outcomes and advanced biomechanical performance.
Surface area is magnified by

modular spinal platform that adapts precisely to your needs.
The finely balanced surface roughness has a positive influence on the adhesion of osteoblasts. The porosity aligns with the human anatomy. This creates a solid basis for bony on-growth and thus fusion with Structan®.[5-8]
Substantial osteoblastic differentiation and improved osseointegration – based on scientific evidence, our AESCULAP® 3D Cages reflect the biological attributes of the trabecular structure, empowering bony in-growth.[9-15]
Smart designed graft window to support osseointegration between bone and implant – with or without autograft or allograft.
The harmonized interface provides a firm connection to instruments and high precision during handling. Feel all of this with our articulating inserter in TLIF procedures – because confidence delivers peace of mind.
AESCULAP® 3D interbody fusion devices
As with the creation of all of our spine solutions, the design of the AESCULAP® 3D interbody fusion devices is based on our core values of creating advanced biomechanical performance, intra-operative flexibility and improved clinical outcomes.

[17] Usability-Test, Usability Validation of AESCULAP® CeSPACE® 3D Cages, Tübingen, 2019.The usability of the AESCULAP® 3D Cage System CeSPACE® 3D was tested in April 2019, in a cadaver workshop with six independent test persons as intended users (surgeons specialized in spinal surgery or comparable fields). Parameters such as implant visibility under x-ray control, mechanical stability of the implant/instrument interface andimplant surface evaluation in terms of tissue injury risk were tested among others. Acceptance criteria were fulfilled for all the above-mentioned parameters. All test users confirmed the absence of critical features that must be improved prior to clinical use. During the test, the x-ray visibility of the cages was particularly positively assessed.
[18] Rehnitz, Christoph, PD Dr. med. Radiological image evaluation of AESCULAP® interbody fusion devices, Heidelberg, 2019. CT and X-ray visualization of different AESCULAP® interbody fusion cages (full titanium, porous Ti6Al4V and PLASMAPOREXP® cages) was tested in a cadaver setup. A radiologist evaluated the implant visibility and the presence of artefacts that may limit the visualization of adjacent structures. Visualization and assessment of implant position was achieved in X-ray and CT for all tested cages. Minor artefacts were visible in CT reconstructions in the surrounding of porous Ti6Al4V and full titanium implants. Porous Ti6Al4V implants showed slightly fewer artefacts in CT in comparison to full titanium implants. The minor artefacts observed did not limit the assessment of the surrounding anatomical structures.
