IPS Implants®

The right "customized" choice for every patient

Patient-specific implants, planning aids, and anatomical models are made from various materials using state-of-the-art fabrication technologies. Thanks to computer-based planning and functionalized patient-specific implants, preoperative planning can be implemented in surgery with unprecedented precision.

Based on the potential planning in our IPS CaseDesigner® software and subsequent case treatment and communication in the IPS Gate®, you will then receive an IPS® implant fabricated to your wishes. As a result, the IPS® product range offers a versatile service in terms of patient-specific implants.

What our users say

Dr. med. Stephan F. Schindele, Schulthess Clinic, Zurich, Switzerland: "The 3-dimensional reconstruction of fractures of the forearm that have healed in a deformed position has meanwhile proven its worth at various centers and good results have been reported in the literature for this still young technique to this day. This technique increases the precision of the correction on the one hand and shortens the duration of the operation on the other hand. Especially in complex reconstructions with rotational malpositions the use of this technique is indispensable. The fixation of the correction with an individual implant also in many cases does justice to the individual anatomy in each case."

Dr. Jan-Ragnar Haugstvedt, Østfold Hospital, Moss, Norway: "After many years as a hand surgeon, one of the most challenging procedures to perform is correction of malunited forearm fractures that the patient suffered from in childhood. Using 3D reconstruction of the contralateral (non-injured) arm, and patient-specific guides and plates, the correction has been made “easy” with good results and happy patients."

Dr. med. Philip Grieve, Blackrock Clinic, Dublin, Ireland: "With regards to the case in question, I simply wouldn’t have been able to treat this complex intra-articular malunion effectively without a patient specific implant and the 3D planning involved. On the day of surgery the support KLS Martin provided was top class and ensured the surgery was performed to the highest standard possible. I’m looking forward to my next case already."

Dr. med. Niels Schep, Maasstad Ziekenhuis Rotterdam, Netherlands: "IPS® provides me with the tools to plan and execute complex extra-articular malunions of the distal radius. Moreover, recently we also successfully completed intra-articular corrections with the help of patient-specific 3D-printed guides and titanium plates."

MUDr. Radek Kebrle, Vysoke nad Jizerou Hospital, Czech Republic: "3D planning and customized 3D printing in reconstructive surgery start to be inevitable solution for certain pathologies. Their use during reconstruction of intraarticular malunions of distal radius gives us a chance to reconstruct more complex cases that would be otherwise indicated for salvage."

Generative manufacturing process,
additive manufacturing

Selective Lasermelting

Selective laser melting (SLM) is a 3D printing process in the context of a generative manufacturing process.
Titanium powder is fed from a high pressure chamber into a working chamber via a scraper or roller. A laser beam is reflected into the working chamber with a mirror where it falls on the titanium powder. The impact of the laser beam melts the powder (hence the term laser melting) and compresses it. Once the laser has processed one working plane, the working platform (table) is lowered and a new layer of titanium powder is applied. Thus the workpiece is manufactured layer after layer. As the performance density of the laser is extremely high, this leads to highly compressed three-dimensional workpieces.
This manufacturing process allows the fabrication of patient-specific implants from additive manufactured titanium.
 

Selective laser sintering and stereolithography

Selective laser sintering and stereolithography also count as generative manufacturing processes. Selective laser sintering (SLS) follows the same functional principle as selective laser melting, the difference being that the starting materials used are all materials with thermoplastic properties. Resin powder (e.g. polyamide (PA)) is a frequently used material. Drill and marking guides or anatomical models are manufactured using this method.

In stereolithography (SLA), the workpiece is positioned in a photopolymer liquid bath (e.g. epoxy resin) in which it is slowly immersed deeper and deeper. During each step a laser passes over the starting material to harden it in thin layers in order to create the desired shape.

The stereolithography process is the 3D printing process which has so far been in use the longest, so that a considerable amount of experience has been gained. In general this method is used for fabricating anatomical models.

Materials of the IPS Implants®

Additive manufacturing titanium

Completely free surfaces can be generated without tools and devices. This allows for hitherto unprecedented options in surface design.
Correction processes are no longer required.

Material: Ti-alloy Ti6Al4V
Specified according to: ASTM F136 -02a (ELI Grade 23)
Sterilization: steam sterilization at 132 °C
EN 285 / ANSIA / AAMI / ISO 11134 – 1993

Benefits:

  • Complete freedom of design of the material and its surface
  • Exact precision fit
  • High stability
  • Open structures are possible
  • Fast

Limitations: 

  • If necessary, revision procedures are only possible with considerable effort
  • Intraoperative trimming is virtually impossible

The easy way to IPS Implants®

To start the patient-specific planning the patient data and other case-related information is uploaded onto the IPS Gate® as a first step. IPS Gate® is a platform that reliably and efficiently guides users through the process of requesting, planning including possible corrections and finishing patient-specific products. The intuitive concept offers users maximum mobility, flexibility and functionality. 

IPS® developers then check the quality of the data and prepare the case planning with the information and requirements of the users provided in advance. The integrated chat function enables direct contact and direct communication between the persons involved. Via chat communication and web meetings, case plannings and product designs are discussed, adapted and if necessary revised together.

If the design meets the user's requirements, he or she can digitally release the design for production directly via the IPS Gate®. Simultaneously, the users receive the economic offer and confirm this by sending the official order.

As soon as the users have given their approval, production of the IPS Implants® starts. The products are then shipped to the users as quickly as possible and can be used during surgery.

Legal basis for IPS Implants®

According to the regulations of the MPG (Medical Device Act) §3 Sentence 8, a custom-made product is a medical device manufactured on prescription according to specific design specifications and which is intended for the exclusive use for a named patient. For this reason a separate inquiry is necessary in every case.

The written prescription is a release for the technical offer (design of the products). This is to be submitted in writing by the user at the same time as the required order for the economic offer if he/she agrees with the desired case planning.

Shipment is not permissible as a matter of principle without this mandatory regulatory document.
