The DePuy Synthes 2.7mm VA LCP Clavicle Plate System is indicated for fixation of fractures, and nonunions of the clavicle in adults, and in both adolescents (12-18 years) and transitional adolescents (18-21 years), in which the clavicular growth plates have fused or in which the growth plates will not be crossed by the plate system.
The DePuy Synthes 2.7mm VA LCP Clavicle Hook Plate System is indicated for fixation of lateral clavicle fractures and dislocations of the acromioclavicular joint.
The DePuy Synthes 2.7mm VA LCP Clavicle Plate System consists of lateral, shaft and medial plates designed for temporary fixation, correction or stabilization of clavicle bones. The subject plates are available in various sizes in both sterile and non-sterile configurations and are available in stainless steel and titanium alloy. The system also consists of non-implantable templates that correspond to the implants. Templates are intended for implant size selection and are available in non-sterile.
The DePuy Synthes 2.7mm VA LCP Clavicle Hook Plate System consists of the plate types Long, Short and Button which can be used to treat simple and complex clavicle fractures including malunions, non- unions and isolated ligamentous injuries of the AC joint. The subject plates are available in three hook depths, in left- and right-side versions, in both sterile and non-sterile configurations and are available in stainless steel and titanium. The system also consists of non- implantable templates that correspond to the implants. Templates are intended for implant size selection and are available non-sterile.
The provided text is a 510(k) Pre-market Notification for two medical devices: the DePuy Synthes 2.7mm VA LCP Clavicle Plate System and the DePuy Synthes 2.7mm VA LCP Clavicle Hook Plate System. This type of submission is for demonstrating substantial equivalence to a legally marketed predicate device, rather than proving the device meets specific acceptance criteria through extensive studies in the way a novel device might.
Therefore, the document explicitly states that "Non-clinical performance data was not necessary for the determination of substantial equivalence" and "Clinical testing was not necessary for the determination of substantial equivalence". This means there are no acceptance criteria, device performance data, sample sizes, expert ground truth, adjudication methods, MRMC studies, or standalone algorithm performance studies described in this document.
The basis for clearance is that the subject devices (DePuy Synthes 2.7mm VA LCP Clavicle Plate System and DePuy Synthes 2.7mm VA LCP Clavicle Hook Plate System) are substantially equivalent to previously cleared predicate devices (K201321 and K201959, respectively). The manufacturer asserts that the design, features, and specifications (technological characteristics) of the subject devices remain unchanged compared to their respective predicate devices. Any differences (e.g., additional contraindications or sterile/non-sterile options for the hook plate system) are argued not to raise new questions of safety and effectiveness.
In summary, this document does not contain the information requested about acceptance criteria and a study proving device performance because such studies were deemed unnecessary for a 510(k) submission based on substantial equivalence.

The DePuy Synthes 2.7mm VA LCP Clavice Plate System is indicated for fixation of fractures, and nonunions of the clavicle in adults, and in both adolescents (12-18 years) and transitional adolescents (18-21 years), in which the clavicular growth plates have fused or in which the growth plates will not be crossed by the plate system.
The DePuy Synthes 2.7mm VA LCP Clavicle Plate System consists of lateral, shaft and medial plates designed for temporary fixation, correction or stabilization of clavicle bones. The subject plates are available in various sizes in both sterile and non-sterile configurations and are available in stainless steel and titanium alloy. The system also consists of non-implantable templates that correspond to the implants. Templates are intended for implant size selection and are available in non-sterile.
This submission describes a medical device, the DePuy Synthes 2.7mm VA LCP Clavicle Plate System, and its substantial equivalence to predicate devices, rather than a study evaluating the performance of an AI-powered diagnostic device against specific acceptance criteria. Therefore, most of the requested information regarding acceptance criteria, study design, expert involvement, and performance metrics for an AI system is not applicable to this document.
However, I can extract and structure the relevant information regarding the device acceptance and the studies conducted to support its substantial equivalence.
1. Table of Acceptance Criteria and Reported Device Performance
| Category | Acceptance Criteria | Reported Device Performance |
|---|---|---|
| Mechanical Performance | Mechanical performance of the subject devices (DePuy Synthes 2.7mm VA LCP Clavicle Plates) is at least equivalent to that of the predicate devices (DePuy Synthes 3.5mm LCP Reconstruction Plates). | Static and cyclic mechanical testing of constructs has been performed to compare the subject DePuy Synthes 2.7mm VA LCP Clavicle Plates to the predicate DePuy Synthes 3.5mm LCP Reconstruction Plates. This information supports that the mechanical performance of the subject devices is at least equivalent to that of the predicate devices. |
| Magnetic Resonance (MR) Compatibility | Establish MR Conditional parameters for the subject DePuy Synthes 2.7mm VA LCP Clavicle Plates. | Magnetic Resonance compatibility testing has been performed to establish MR Conditional parameters for the subject DePuy Synthes 2.7mm VA LCP Clavicle Plates. |

2. Sample Size Used for the Test Set and Data Provenance
- Test Set Sample Size: Not specified for any of the non-clinical tests. For mechanical testing, samples of constructs (presumably plate-bone models) would have been used, but the specific number is not stated. Same for MR compatibility, endotoxin, and biocompatibility - "testing has been performed" implies a sample set was used, but the size is absent from this summary.
- Data Provenance: The studies are described as "non-clinical performance data." This strongly suggests laboratory-based testing rather than patient data. No country of origin is specified for the data itself, but the manufacturer is Synthes GMBH, Switzerland, and the sponsor (DePuy Synthes) also has a US address (West Chester, PA). The testing appears to be retrospective, as it was conducted to support a premarket notification for an existing device design.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts
- Not Applicable. This document describes non-clinical testing of a medical implant, not an AI diagnostic device where expert ground truth is typically assessed. The "ground truth" for these tests would be the measured physical, chemical, or biological properties conforming to established standards and predicate device performance.
4. Adjudication Method for the Test Set
- Not Applicable. As this is not an AI diagnostic study involving human interpretation of results against a gold standard, no adjudication method is relevant.
5. If a Multi Reader Multi Case (MRMC) Comparative Effectiveness Study Was Done, If so, What Was the Effect Size of How Much Human Readers Improve with AI vs Without AI Assistance
- No. This is not an AI-powered diagnostic device, and therefore, no MRMC study or assessment of human reader improvement with AI assistance was conducted or reported.
6. If a Standalone (i.e. algorithm only without human-in-the loop performance) Was Done
- Not Applicable. This is a physical medical device (clavicle plate system), not an algorithm or AI system.
7. The Type of Ground Truth Used
- For Mechanical Performance: The "ground truth" is the established mechanical properties of the predicate device (DePuy Synthes 3.5mm LCP Reconstruction Plate) and relevant engineering standards for bone fixation devices. The subject device's performance is compared against these benchmarks.
- For MR Compatibility: The "ground truth" is the established MR conditional parameters based on standardized testing procedures.
- For Endotoxin: The "ground truth" is the regulatory specified endotoxin limit (20 EU/device) for sterile devices. The LAL test method is a standard to determine this.
- For Biocompatibility: The "ground truth" is established biological safety criteria as defined by ISO 10993-1, which guides biocompatibility evaluation and testing.
8. The Sample Size for the Training Set
- Not Applicable. This is not an AI/machine learning device that requires a training set. The device is a physical implant.
9. How the Ground Truth for the Training Set Was Established
- Not Applicable. No training set for an algorithm is involved.
