Patient-specific acetabular implants designed to break the revision cycle.
Augment the predictability, trust the outcome.
Up to 27% of hip revisions are re-revisions due to a suboptimal fixation and suboptimal biomechanical reconstruction of the joint1 when combining standard components. What’s even worse, hip re-revisions are 3 times more likely to fail compared to a primary acetabular revision2. Fortunately, you can break this downward spiral. Meet Materialise aMace, the personalized one-piece solution with a 98% implant survival3 and 100% patient satisfaction rate4.

Example of a Personalized 3D-Printed Hip Arthroplasty
This video demonstrates how Dr. Van Hellemondt and Dr. Spruit (Sint-Maartenskliniek Nijmegen, The Netherlands) performed a total hip arthroplasty to reconstruct a large acetabular defect, more specifically a Paprosky 3B defect, by implementing the Materialise aMace hip solution.
“The aMace implant was preferred over other solutions because it offers a complete solution, much more patient-specific than any other commercially available implant, through calculations – scientifically validated by peer-reviewed research - of the optimal implant thickness and strength, best position of screws according to bone quality and analysis of the impact on biomechanical functioning of a specific patient. This solution offers the possibility to regain full quality of life for patients with complex acetabular defects, lowers the risk of re-revisions, immobility and permanent care.”
“Does what it says on the tin. Interfacing with the engineers is straightforward and first rate, leaving you with a sense of confidence, which is an important part of a surgeon’s pre-operative approach to these challenging cases. The preoperative planning allows you to have the flexibility of thinking on beforehand. It was a game-changing procedure for me and takes the stress out of it. It speeds everything up.”
“The major benefit is the preoperative planning and defect analysis that really prepares one for surgery. No surprises during surgery is great! The difference to off-the-shelf products is that Materialise aMace is customized to the defect instead of customizing a defect to the implant. My first case has 6 years follow-up and he is still doing great!”
“I was confident that the aMace implant was the right choice for my patient because of the attention for the biomechanical aspect in the design of the implant. Materialise showed me my patient’s bone quality, designed the implant and positioned the screws accordingly. This smooth cooperation with the Materialise team resulted in a swift operation and a faster recovery for my patient.”
“To me, reducing your surgical time is an important advantage of these custom-made implants. I’m very well prepared before I go into an operation. It’s like having a manual: I know what to do, I know the bone quality, I know the good and the bad parts of the pelvis. On top of that, I hold accurate models of the hemi-pelvis in my hands. They’re extremely handy as I can look at them while simultaneously looking down into the wounds. Additionally, the drill guides give me confidence about the positioning of the screws, which helps saving time as well. And the implant is patient-specific, so I don’t have to bend flanges or anything. Having the anatomic reconstruction planned before the operation means you need less instrumentation and fewer trials because you already know which implant you’re going to use. Less work for the nurses!”
Frequently asked questions

If I have an interesting case, to whom should I reach out to ask for more information on the process and pricing?
Please contact email@example.com and our team will make sure that your request is followed up.
Can I plan my own clinical cases in a hospital and ask Materialise to provide guides and/or implants?
No, we do not provide unique printing services as we consider the planning and design an integral part of the quality assurance of our products.
Is Materialise able to support research projects or clinical projects?
We are involved in research and clinical projects, but evaluate such projects on a case-by-case basis.
What are the advantages of a trabecular structure in an implant?
Osseointegration (the potential for bone in-growth) is the most important advantage, but there are more reasons to opt for a porous structure. The material properties of the porous structure better match the mechanical properties of the bone. In addition, given the potential large size of the defect-filling implants, porous structures allow to reduce the total weight of the implant.
What is the link between Materialise and J&J /DePuy Synthes?
Where can I find the sterilization procedures that are recommended for guides, models and implants?
You can find all procedures in the instructions for use of the respective products. Contact your account manager to request a copy.
