HipStudio Simulation Service is an online image analysis service indicated for skeletally mature individuals that are suspected of suffering from symptomatic or asymptomatic hip conditions including but not limited to developmental dysplasia of the hip (DDH) and femoroacetabular impingement (FAI). It enables clinicians to obtain 3D motion simulation reports based on CT image data. The service can be used by uploading CT image data of hip joints. The image data is processed by Replasia to create 3D anatomy models. These 3D models are then used to perform 3D motion simulations of the hip joint for different treatment approaches and to calculate bone-to-bone contact points where impingement occurs. The HipStudio Simulation Service also calculates several morphological shape parameters for each of the 3D anatomy models. The software generates a report as output. Clinicians do not interact with the image analysis software directly. The image analysis software is only operated by Replasia operators who have been specifically trained for this purpose. End users of the generated HipStudio Simulation Service reports are trained medical professionals, including radiologists and orthopedic surgeons.

HipStudio Simulation Service
- perform detailed analyses and kinematic simulations of the patient's anatomy, generating clinically relevant data for assessing hip conditions.
- simulate treatment approaches for various hip conditions, including surgical procedures like the removal of bone parts for FAI. It also supports non-surgical treatments.
The service workflow consists of three steps:
1. Case creation and incoming data inspection
2. Image segmentation and 3D model generation
3. HipStudio analysis and treatment assessment
Case creation and incoming data inspection
The HipStudio Simulation Service uses the LiquidFiles software application for communication and data exchange with the treating physician. Clinical cases are initiated by the treating physician through the secure file transfer portal, which supports end-to-end encryption and full audit logging. Upon upload, imaging data (i.e. CT scan data) are transmitted via encrypted channels and stored in a controlled-access environment.
Authorized, trained Replasia personnel access the data to perform an initial technical quality check to confirm suitability for the intended analysis.
Immediately thereafter, all datasets undergo a structured pseudonymization process using Mimics software from Materialise [K073468], in which direct identifiers are removed or replaced. Following successful pseudonymization, the original identifiable files are permanently deleted in accordance with data minimization policies.
All processing steps are conducted under strict access controls and user authentication to ensure compliance with applicable data protection and medical data security requirements.
Image segmentation and 3D model generation
The pseudonymized CT images are processed by Replasia using Mimics software from Materialise [K073468]. During this step, the anatomical structures of the hip are delineated in the grayscale images, based on Hounsfield units, texture and shape. Next, three-dimensional representations (i.e. 3D models) of said structures are calculated by the software. These serve as input for the third and final step.
HipStudio analysis and treatment assessment
In this step, proprietary Replasia software, HipStudio is used by trained Replasia personnel to analyze the joint's morphology, perform kinematic simulations and virtually simulate (surgical and/or non-surgical) hip preservation treatments using the previously generated three-dimensional representations of the hip anatomy. Clinicians do not interact with the analysis software directly.
HipStudio generates a comprehensive digital report based on the performed analyses. The report is shared with the treating physician through the LiquidFiles platform. If necessary, a separate online session is organized to discuss the results of the analysis with the surgeon.

## 7. Non-Clinical Performance Data.
The non-clinical performance of the HipStudio Simulation Service was evaluated through a comprehensive V&V program conducted in accordance with applicable FDA guidance for quantitative imaging devices, recognized consensus standards, and Replasia's quality management system.
The HipStudio Simulation Service incorporates three software applications within its workflow: LiquidFiles, Mimics, and HipStudio. LiquidFiles is a commercially available secure file transfer application used for encrypted communication between Replasia and the treating physician. Mimics (Materialise NV; FDA-cleared under K073468) is a commercially available medical image processing software application used for pseudonymization, image segmentation, and generation of patient-specific three-dimensional anatomical models from CT and/or MR image data. HipStudio is proprietary software developed by Replasia and is used by trained Replasia personnel to perform anatomical measurements, kinematic simulations, impingement analyses, and generation of the HipStudio Simulation Service report.
The HipStudio software was developed in accordance with IEC 62304:2006+A1:2015 and has been classified as Moderate Level of Concern software consistent with applicable FDA guidance. Software verification and validation activities were performed for the commercial release version (v1.4) and included functional verification, verification of generated report outputs, and cybersecurity verification.
Technical performance testing included evaluation of segmentation accuracy, algorithmic accuracy, repeatability, reproducibility, statistical shape model validation, report output verification, usability validation, clinical association validation, and predicate output equivalence.
Segmentation accuracy was supported by published validation studies demonstrating submillimeter accuracy of the upstream segmentation process performed using Mimics. Algorithmic accuracy testing using a Digital Reference Object demonstrated exact agreement between software-generated measurements and predefined ground truth values. Repeatability and reproducibility testing demonstrated acceptable precision and consistency for evaluated quantitative measurements and simulation outputs.
Clinical association was established through a structured literature-based clinical association matrix that mapped each reported parameter and simulation output to established clinical concepts used in the assessment and treatment planning of hip disorders. The clinical association matrix was independently reviewed by six experienced orthopedic hip surgeons, all of whom confirmed that the reported parameters are clinically recognized, relevant to hip morphology assessment and treatment planning, and presented in a clinically interpretable manner.
Usability testing demonstrated that intended users could correctly interpret the information presented in the generated reports. Predicate output equivalence testing demonstrated comparable report content, quantitative measurements, and clinical information between the

Part 1 — Search, results, and everyday workflows 16 min
Part 2 — Embeddings: the galaxy map 3 min
1. Search: exact and fuzzy
Type a phrase like "coronary artery calcification" into the search box. You get two kinds of results. Exact results match the literal phrase — prefix searches work ("coronary artery calcificati") but suffix searches do not. Fuzzy results match on the meaning and intent of your phrase rather than the exact words, and are sorted by relevance score. Hover over the Exact or Fuzzy badge on any row to see exactly why it matched.
Use the checkboxes above the results to narrow: SaMD keeps only Software as a Medical Device, AI / ML keeps only devices with AI.
Exact vs. fuzzy search: what's the difference?
Exact matches on the literal phrase (prefix search works, suffix does not). Fuzzy matches on the meaning and intent of the phrase rather than the exact words. Hover over the badge on any row to see why it matched.
You search "coronary artery calcification" and want only software devices with AI. What two filters do you apply?
Narrow by SaMD (Software as a Medical Device), then narrow by AI/ML (devices with AI).
2. The results table
Scroll right in the results table. The intended use is extracted for you — no need to open the PDF. The device story gives a high-level snapshot of what the device does and how it's used. The AI Performance sub-table shows each output name, acceptance criteria, observed values, and development/test dataset descriptions — the same format Innolitics uses for regulatory strategy outputs, and the fastest high-level fingerprint of an AI device. It is AI-generated but has been very reliable in practice.
Where do you find a device's intended use without opening the PDF?
Scroll right in the search results table. The intended use column is extracted for you; no need to dig into the 510(k) summary PDF.
What does the AI Performance sub-table show, and why is it useful?
Output name, acceptance criteria, observed values, development dataset description, and test dataset description. It's the same format we use for regulatory strategy output and Fast 510(k) input, and the fastest high-level fingerprint of an AI device. AI-generated but reliable in practice.
3. Judging fuzzy relevance
Fuzzy results trail off in relevance as you scroll. Use three signals to decide how far down to go: the fuzzy badge explanations, the intended use column, and whether your target output (e.g., Cobb angle) still appears in the AI Performance sub-table. Once it stops appearing, you're past the relevant zone. A top hit with a low score (~0.4) and a stretched explanation is a hint the closest predicates are far away — the project may be headed for De Novo. Note the fuzzy search is a pattern match: it doesn't handle negation ("not") well, and hardware devices can appear — filter by SaMD/AI ML to cut them.
How do you judge how far down fuzzy search results to go?
Use the relevancy signals: the fuzzy badge explanations, the intended use column, and whether the target output (e.g., Cobb angle) still appears in the AI Performance sub-table. Once it stops appearing, results are trailing off in relevancy.
4. Device detail page: chat and citations
Click a device name to open its detail page: device facts on the left, a chat window on the right. Ask something like "Describe the training data". The answer carries little citation bubbles — click one to jump to the highlighted passage in the source PDF, so you can verify every AI answer against the document. There's also a Download PDF button for sharing.
How do you verify an AI chat answer on the device detail page?
Click the citation bubbles to jump to the relevant highlight in the source document.
Reading rule for every project: how many summaries do you read in full?
At least the three most relevant 510(k) or De Novo summaries, in full. After that, use targeted chat questions to confirm your memory quickly. The tool supports this professional habit — it doesn't replace it.
5. Side-by-side comparison
Select multiple rows in the results table (aim for under ~10), then open the PDF Viewer tab. Ask one question — it goes to all selected devices in parallel, each with citations. This is the fastest way to compare and contrast devices: training data, PCCP scope, how they handled adding new scanners, and so on.
What does the side-by-side PDF viewer mode do?
Select multiple devices, open the PDF viewer tab, and ask one question (e.g., "Describe the training data"). It queries all selected devices simultaneously with citations, so you can compare and contrast quickly.
6. Collections
With rows selected, go to the Collections tab and create a labeled collection (e.g., "Cobb Angle Project"). Reload that selection any time — before a client call, pull up the collection and ask questions across all of its devices at once.
How do you save a set of selected devices for later use?
Select the rows, go to the Collections tab, and create a labeled collection (e.g., "Cobb Angle Project"). You can reload the selection anytime and carry it into the PDF viewer and other tabs that support selections.
7. Product codes and the regulations tree
Click a product code in the results to jump to it in the regulations tree — identification text, sibling product codes, and devices you can open in a PDF viewer on the right. Click a regulation number to see its identification, special controls, and related product codes. You can also search by product code or regulation number at the top of the tree. Always read the special controls if any exist for your device — it broadens your search and sharpens pre-kickoff research.
What can you do from the regulations tree view?
Browse product codes and regulation numbers, read the identification text and special controls, browse sibling product codes, open device PDFs on the right, and search by product code or regulation number at the top of the tree.
8. Chart view
Click Show Chart and segment by regulation number (or product code) to see which regulations dominate your result set. Clicking a regulation takes you into the regulations tree. Great for spotting that most matches are, say, hardware laparoscopic devices — a cue to go back and filter.
How do you see which regulations dominate a search result set?
Click "Show Chart" and segment by Regulation Number. Clicking a regulation takes you to the regulations tree.
9. The predicate graph
Open the Predicates tab for a family-tree view of predicate relationships. Click a node to trace its parents and children; selections from search carry over pre-selected. Commonly predicated devices are worth reading — a lot of people predicated them for a reason. The visual lineage is also handy on client calls, e.g. to show how a predicate family evolved and justify why your predicate still holds.
In the predicate graph, why are commonly predicated devices worth reading?
A lot of people predicated them for a reason. Clicking a node traces parents and children, and selections from search carry over pre-selected.
10. Embeddings: the galaxy map
The Embeddings tab plots every matching document in a 2-D "galaxy map" where semantically similar devices cluster together. Hover or click clusters to explore, and let AI label the clusters for you. Embeddings beat product codes for grouping: two devices can carry different product codes (LLZ vs. QIH) yet do the same thing — the embedding captures the meaning of the intended use and device story. This is also exactly how retrieval-augmented generation (RAG) works under the hood, and it makes a great visual on client calls.
Try it yourself
Head to the search page and work through a few of these AI/ML fuzzy searches to build intuition: perivascular fat on CT · aortic valve calcification opportunistic screening on noncontrast CT · breast cancer prediction on digital pathology slides · autism detection · gestational age prediction · a hearing aid that can also detect a pulse · foundation model based analysis of ECG · large language models · penetration test. Watch how the relevance scores, intended use, and AI Performance tables tell you when results stop being meaningful.
