All IPS® data uploads takes place via IPS® Gate, our proprietary cloud-based case management system.

Following data validation, a planning session commences where the distraction device, distance, and vectors are defined. Bone thickness may also be analyzed for confirmation that screws are being placed in adequate locations.

Our guides are designed with predictive screw locations and carefully planned osteotomies for improved precision. Crafted from durable materials like Polyamide or Titanium, our guides provide lasting support and accuracy.

The fixation plates are based on the patient's individual CT scan and are validated against patient anatomy to confirm a precise fit. Our IPS® distractors are available in 4 different body styles, allowing for a high degree of individuality.

The IPS® Distractors are based on our standard portfolio. The standard distractors serve not only as a reference for planning but also for the indications of the respective IPS® Distractor. Our IPS® Distractors have the same geometries and technical properties as the standard IPS®, hence, all standard accessories such as activation arms and instruments can be used without difficulty.

1. IPS® planning

The first step of IPS® planning is to upload patient information into IPS® Gate.

IPS® Gate, a cloud-based case management system for patient-specific cases, allows users to access patient information and archived cases.

Through an integrated chat function and web meetings, users communicate directly with an IPS® engineer. During the IPS® planning session, the IPS® engineer and the surgeon discuss the osteotomy, screw locations, and product preferences.

2. Insertion of the guides and performing the osteotomy

In addition to providing predictive screw locations, IPS® Distraction guides incorporate fixation holes. These holes allow the user to fixate the guide while pre-drilling the predictive screw locations.

The first step of performing the osteotomy involves exposing the bone that needs to be distracted.

Next, the distractor is adapted to the bone in the required distraction vector. To mark the position accurately, at least two screw holes are pre-drilled on each side of the osteotomy line.

The guide is removed once the marking is complete and the osteotomy is performed. It is highly recommended to ensure complete separation of the bone during this step.

3. Fixation of the distractors

The final step involves securing the distractor firmly using appropriate screws. Additionally, an intraoperative test is performed to assess the activation of the distractor. During this stage, it is crucial to thoroughly inspect the entire osteotomy and ensure that the device activation process occurs smoothly without encountering any resistance.

4. Latency period

Prior to distracting, the user must determine the appropriate latency period. Generally, this is around 1-7 days, depending on the patient's age.

5. Distraction period

About 1mm of distraction is then performed per day using the screwdriver corresponding to the device. An arrow on the driver indicates the correct direction. 

6. Consolidation period

During the consolidation period, which comes after the distraction period, it is important to note that the activation arm may be removed.

A period predetermined by the surgeon is generally allotted for post-distraction bony consolidation. 

7. Removal of the distractor

Following consolidation, the distractor may be explanted.
