IB Lab LAMA
IB Lab GmbH
IB Lab LAMA is a fully-automated radiological image processing software device intended to aid users in the measurement of limb-length discrepancy and quantitative knee alignment parameters on uni- and bilateral AP full leg radiographs of individuals at least 22 years of age. It should not be used in-lieu of full patient evaluation or solely relied upon to make or confirm a diagnosis. The software device is intended to be used by healthcare professionals trained in radiology. IB Lab LAMA is not indicated for use on radiographs on which Ankle Arthroplasties and-or Unicompartmental Knee Arthroplasties are present.
Evidence status: each field states its source quality, applicability, and review date. Research pending, information not established, and vendor documentation pending remain distinct outcomes.

What this tool is for
Start with the authorized purpose, then verify how it fits your service line and reading workflow.
- Exact purpose
- IB Lab LAMA is a fully-automated radiological image processing software device intended to aid users in the measurement of limb-length discrepancy and quantitative knee alignment parameters on uni- and bilateral AP full leg radiographs of individuals at least 22 years of age. It should not be used in-lieu of full patient evaluation or solely relied upon to make or confirm a diagnosis. The software device is intended to be used by healthcare professionals trained in radiology. IB Lab LAMA is not indicated for use on radiographs on which Ankle Arthroplasties and-or Unicompartmental Knee Arthroplasties are present.
Clinical-use display mirrors the best exact-submission purpose source because the reviewed FDA packet did not provide a more specific usable abstraction.
- Intended users
- Healthcare professionals trained in radiology

- Care setting and population
- Adult
Patient-population text reported in the exact-submission ACR model card; institutional setting may still require vendor confirmation.

- Required input
- X-ray/Radiography images or data involving MSK; consult the FDA labeling for exact protocol, series, and quality requirements.

- Output and human action
- The AI model outputs fully-automated geometric length and angle measurements of the lower limb including: mechanical axis deviation (MAD), full leg length, femur length, tibia length, leg length discrepancy (LLD), hip knee ankle angle (HKA), anatomical tibiofemoral angle (aTFA), anatomical mechanical angle (AMA), joint-line convergence angle (JLCA), mechanical lateral proximal femoral angle (mLPFA), mechanical lateral distal femoral angle (mLDFA), mechanical medial proximal tibia angle (mMPTA), and mechanical lateral distal tibia angle (mLDTA). Secondary output includes arthroplasty detection (TKA and THA). Results are summarized in human and machine readable DICOM format reports. The user can accept or reject the generated report findings.

Regulatory identity
FDA record and catalog context
The FDA listing establishes the regulatory identity. It does not by itself establish local workflow fit, pricing, security, or performance in your environment.
Implementation
Questions for IT, informatics, and operations
Use these fields to structure a vendor demo, security review, and implementation estimate.
- Integration
- The exact-submission ACR model card explicitly references DICOM in the described input, output, or workflow; exact interfaces, versions, and local compatibility require confirmation.
Interoperability terms explicitly reported in the exact-submission ACR model card; interface versions and local compatibility still require confirmation.
- Deployment and data flow
- On-premise
Deployment category preserved from the prior exact-submission review; hosting region, data flow, and current commercial configuration still require vendor confirmation.
- Security and privacy
- Vendor documentation pending
Exact-release security controls, data retention, hosting boundaries, and scoped assurance documentation require vendor confirmation.
- Training and support
- Vendor documentation pending
Current training prerequisites, competency checks, and support commitments for the exact configuration require vendor confirmation.
- Monitoring and change control
- Vendor documentation pending
Current drift, quality, uptime, alert, escalation, and incident-response commitments for the exact configuration require vendor confirmation.

Performance evidence
Metrics are shown only when they are tied to a source, endpoint, population, and tested product version. Candidate literature without exact product and version linkage is not shown as product evidence.

Costs and setup
Budget and ongoing governance
These are common procurement questions; unknown values remain visible until a source supports them.
- Pricing and total cost
- Vendor documentation pending
No public price or quote for the exact K223646 configuration was established in this review.
- Reimbursement and coding
- Not established in reviewed sources
No exact-product payer policy, coding instruction, or payment determination was established; eligibility must be evaluated by payer, site of service, and use case.
Safety and lifecycle
Postmarket record
Recall and adverse-event records are shown only after product matching. Adverse-event reports do not establish incidence or causality.
- Postmarket safety review
- The exact-identifier FDA recall query returned no native recall record for K223646. This limited result does not establish absence of recalls or other safety information and does not cover later versions, family records, MAUDE reports, corrections, or field notices.
Buyer worksheet
Open questions to take to the vendor
- Verify security and privacy controls: Exact-release security controls, data retention, hosting boundaries, and scoped assurance documentation require vendor confirmation.
- Verify training: Current training prerequisites, competency checks, and support commitments for the exact configuration require vendor confirmation.
- Verify pricing and total cost: No public price or quote for the exact K223646 configuration was established in this review.
- Verify reimbursement and coding relevance: No exact-product payer policy, coding instruction, or payment determination was established; eligibility must be evaluated by payer, site of service, and use case.
- Verify local validation and lifecycle monitoring: Current drift, quality, uptime, alert, escalation, and incident-response commitments for the exact configuration require vendor confirmation.

Exact-submission ACR model-card fields were normalized under the current provenance rules; vendor and independent-study confirmation remain distinct. Exact FDA and recall packets were prepared and identity matched, but no new clinical or performance claim was promoted in the conservative fallback. Existing exact-submission facts retain their original source status and applicability; candidate literature remains quarantined. Automated exact-name discovery found 0 PubMed and 0 ClinicalTrials.gov candidate records. Candidates require human product and version matching; zero candidates is not evidence that no studies exist. Native FDA recall identifiers produced 0 postmarket candidate records; 0 have been reviewed (0 published, 0 rejected) and 0 remain unreviewed.
Candidate leads remain unpublished until a human confirms the exact product and tested version.
