Device Story
Secur-Fit Advanced is a tapered, non-porous coated femoral stem for cementless, press-fit hip arthroplasty. Device features proximal normalizations on anterior/posterior aspects to convert shear stresses to compressive forces, facilitating stability and proximal loading. Manufactured from Ti-6Al-4V substrate with CP Titanium and hydroxylapatite (HA) coating. Includes 16 sizes with dual head offsets and shot-peened neck. Used by orthopedic surgeons in clinical settings for primary or revision total/hemi-hip arthroplasty. Device is intended to alleviate pain and restore joint function. Compatible with specific Howmedica Osteonics femoral heads and acetabular components.
Clinical Evidence
Bench testing only. Distal stem fatigue testing (ISO 7206-4) and neck fatigue testing (ISO 7206-6) were performed to verify mechanical integrity and equivalence to predicate devices.
Indicated for patients with noninflammatory degenerative joint disease (osteoarthritis, avascular necrosis), rheumatoid arthritis, functional deformity, failed prior procedures, or proximal femur fractures (nonunions, femoral neck, trochanteric) requiring total or hemiarthroplasty. Constrained liner use indicated for patients at high risk of dislocation due to prior history, bone loss, soft tissue laxity, neuromuscular disease, or intra-operative instability.
Regulatory Classification
Identification
A hip joint metal/ceramic/polymer semi-constrained cemented or nonporous uncemented prosthesis is a device intended to be implanted to replace a hip joint. This device limits translation and rotation in one or more planes via the geometry of its articulating surfaces. It has no linkage across-the-joint. The two-part femoral component consists of a femoral stem made of alloys to be fixed in the intramedullary canal of the femur by impaction with or without use of bone cement. The proximal end of the femoral stem is tapered with a surface that ensures positive locking with the spherical ceramic (aluminium oxide, A12 03 ) head of the femoral component. The acetabular component is made of ultra-high molecular weight polyethylene or ultra-high molecular weight polyethylene reinforced with nonporous metal alloys, and used with or without bone cement.

# Description:
Howmedica Osteonics is introducing the Novel Fit and Fill Hip Stem (aka Secur-Fit Advanced), a tapered non-porous coated femoral stem intended for cementless, press-fit application. The basic design of the Secur-Fit Advanced is similar to other total hip stems that have been commercially distributed such as the Accolade II, Secur-Fit and Rejuvenate Monolithic Hip Stems. The Novel Fit and Fill and the Accolade II stem are
{1}------------------------------------------------
K122853
p.2/3
both made from the same material combinations. The subject device is similar in design to Secur-Fit and Rejuvenate Monolithic as they are straight stems with a normalization pattern. Three dimensional simulations have shown the normalizations on the anterior and posterior aspects of the proximal end of the stem to facilitate press-fit stability and load transmission in the proximal region of the femur. These normalizations are designed to convert medial and lateral shear stresses to compressive forces, which may facilitate proximal loading.
The stem is manufactured from a Ti-6Al-4V substrate material, Commerically Pure (CP) Titanium coating and Purefix hydroxylapatite (HA) coating identical to the previously cleared Accolade II Hip Stem (K103479, K120578).
The Secur-Fit Advanced Hip Stem has a shot peened neck and includes 16 implant sizes 4-12 (nine 132° stems & seven 127° stems) that provide dual head offsets. The stem is designed only for use with compatible Howmedica Osteonics' femoral heads and acetabular components.
## Intended Use:
The Secur-Fit Advanced Hip Stem is a sterile, single-use device intended for use in primary and revision total and hemi- hip arthroplasty to alleviate pain and restore function. The subject hip stem is compatible with V40 heads; C-taper heads, when used with the V40/C-Taper Adaptor Sleeve; Universal Heads, when used with the V40/Universal Adaptor Sleeve; and Unitrax Heads.
# Indications:
Indications for use include:
- Noninflammatory degenerative joint disease including osteoarthritis and avascular l ) necrosis;
- 2) Rheumatoid arthritis;
- 3) Correction of functional deformity:
- Revision procedures where other treatments or devices have failed; and, 4)
- ર) Nonunions, femoral neck and trochanteric fractures of the proximal femur with head involvement that are unmanageable using other techniques.
Additional indication specific to use of Secur-Fit Advanced Hip Stems with compatible Howmedica Osteonics Constrained Liners:
1. When the stem is to be used with compatible Howmedica Osteonics Constrained Liners, the device is intended for use in primary or revision patients at high risk of hip dislocation due to a history of prior dislocation, bone loss, soft tissue laxity, neuromuscular disease, or intra-operative instability.
Secur-Fit Advanced Hip Stems are intended for cementless use only and are intended for total and hemiarthroplasty procedures.
{2}------------------------------------------------
K122 883
## Substantial Equivalence:
The Secur-Fit Advanced Hip Stem is substantially equivalent to other commercially available hip stems in regard to intended use, design, materials and operational principles as a hip prosthesis. The following devices are examples of predicate systems: Accolade II Hip Stem, Secur-Fit HA Hip and Rejuvenate Monolithic Hip Stem. Based upon the mechanical testing, the Secur-Fit Advanced Hip Stem is substantially equivalent for its intended use to other press-fit femoral replacement hip stems currently on the market.
# Summary of Non-Clinical Testing:
The following tests were conducted on the subject device:
- 1) Distal Stem Fatigue Testing in compliance with ISO 7206-4
2) Neck Fatigue Testing in compliance with ISO 7206-6
The results of the above testing verify that the new device is substantially equivalent to the predicate device.

Two short videos show you everything — or skip straight to the written tutorial if you'd rather read. You can reopen this any time from the Tutorial button in the top bar.
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-only devices, 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-only devices), 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.
