The acquired K223779 file contains product-specific indications and users, design and operating principle, recorded comparison and differences, performance evidence actually described, clinical evidence or its stated absence sections. Compare these dated manufacturer statements with your own indication and design before commissioning evidence work. They describe this submission; they do not prescribe your testing, validate performance independently or establish a suitable predicate.

Computed exact-code research
This decision beside its recorded product-code cohort
The 2021–2025 complete-year cohort contains 50 selected decisions under primary code LPH. 50 have valid reported receipt/decision pairs; 0 pairs are missing or invalid.
Calendar elapsed days: lower quartile 75.5, median 156.0, upper quartile 271.5. These are recorded calendar differences, not active FDA review time.
The table shows the named decision and up to four latest exact-code research records through 2026-09-27. It can include partial-year records outside the complete-year cohort. The quartiles above use the full stated cohort, not this displayed selection.

Use this comparison: select a record to investigate, read its actual indications and design, and document differences. A shared code or elapsed period cannot establish its relevance to your device.
Calendar elapsed days are not active FDA review time, a promised schedule or a success probability. The selection includes only the stated recorded decisions, not all applications. Latest records can postdate the named historical decision and are contextual research, not its predicates. Shared codes, summaries and observed records do not prove equivalence, current market availability, buyer applicability or predicate suitability.
Calculation, selection and source versions
Reuse the complete-endpoint exact-primary-code, documented SE-decision cohort and its stated cutoff/window. Retain its type-7 quartiles only when at least 20 valid date pairs are present. Independently subtract the named official record’s receipt date from its decision date; missing or negative pairs remain unknown. Show up to four latest exact-code research records, excluding the named ID. Parent analysis hash, source snapshots and calculation versions are retained.
Calculation: fda-named-decision-cohort-context-1; cutoff 2026-09-27; 17 parent records excluded; units record counts; calendar elapsed days.
Source snapshots: 5a86994ba49a37e71e09be96803fd51981c6c43eaa96caab41aea2b188bfe002.

Recorded evidence and differences to investigate
The summary is manufacturer-submitted context hosted by FDA. Negative/no-study statements are preserved. Evidence themes are not binding legal requirements.
Short opening excerpts identify the source sections. Read the linked original for the full study context, negative statements, tables and limitations. Public quotations are limited to 120 words per acquired summary; the internal evidence packet retains exact section ranges for review.
Indications and users
K223779 · PDF page 3 ↗ Source 2
The hip joint metal uncemented prosthesis is intended to replace a hip joint.
The excerpt is shortened at a complete statement. Read the complete section in the original PDF before interpreting the evidence.
Compare with your product: Compare the recorded indication, population, body site and use environment with your proposed label. Record each change instead of assuming the primary code settles intended use.
Design and operating principle
K223779 · PDF page 4 ↗ Source 3
The EMPOWR™ blade stem represents the latest generation of a press -fit, porous coated, wedge style
femoral stem.
The excerpt is shortened at a complete statement. Read the complete section in the original PDF before interpreting the evidence.
Compare with your product: Compare physical design, materials, energy, accessories and operating principle with your design. Ask which documented differences change the evidence scope.
Recorded comparison and differences
K223779 · PDF page 5 ↗ Source 4
The EMPOWR™ blade stem and accessories are technologically the same when compared to the
predicate Linear Hip Stem (cleared via K120241).
The excerpt is shortened at a complete statement. Read the complete section in the original PDF before interpreting the evidence.
Compare with your product: The summary’s comparison is a manufacturer statement about that submission. Investigate the actual design differences and cited records before considering any comparator or predicate.
Performance evidence actually described
K223779 · PDF page 6 ↗ Source 5
Performance testing was completed on the subject EMPOWR™ blade stem and is detailed in the
Performance Testing section.
The excerpt is shortened at a complete statement. Read the complete section in the original PDF before interpreting the evidence.
Compare with your product: The source labels this section as performance data. Determine which described evidence is bench, software, biological or clinical from the actual narrative and original tables; the section label alone does not settle that distinction or prescribe your testing.
Clinical evidence or its stated absence
K223779 · PDF page 6 ↗ Source 5
No clinical data submitted.
Compare with your product: Preserve whether the summary describes clinical evidence or says none was performed. This recorded case does not determine whether your product needs clinical evidence.
Extraction selection and limits
Select observed whole-line section headings or explicit colon-delimited inline labels on readable PDF pages, including the explicitly documented heading-spacing variants in this parser version. Preserve the original heading, character ranges and layout; do not repair excerpt text. Exclude letter boilerplate and uncertain pages. Stop at observed table headings; do not infer table columns or scalar results from layout text. Multi-column or suspicious split-numeric excerpts are excluded until reviewed alternate extraction is available. Original layout records remain retained; any alternate text has its own extractor-version locator and requires original-page review. For each dimension, prefer usable versioned alternate text where available, selecting its longest usable excerpt; otherwise select the longest usable original-layout excerpt. Ties preserve source order. Bounded to 64 PDF pages and 3,500 characters per section. This is a selection, not a complete dossier analysis.
Excluded extraction items: {}.
Historical references beside dated FDA recognition metadata
Read each mention in the linked original summary, including statements that testing was not performed. Recognition metadata does not determine your testing needs, chosen edition or transition eligibility.

Prepare for your provider: the proposed protocol/report edition, its justification for your device and the complete current FDA recognition sheet. In particular, inspect exclusions for partial recognition. An edition difference does not automatically make the historical evidence unusable.
Identifier-matching method and selection limits
Match explicit ISO/IEC identifiers in selected preserved summary excerpts to the acquired, count-reconciled FDA metadata export. Preserve the historical edition mention, current snapshot designations, entry dates, recognition extent and any recorded transition-expiration date as separate facts. No title-similarity, edition-equivalence, test-mandate or transition-eligibility inference. At most twenty matched occurrences and thirty metadata rows per reference; wide matches are held for separate review.
3 of 3 matched reference occurrences shown.
