The Waveon™ WRx (WristRocket™ Distal Radius System) is intended to be used for the fixation of unstable distal radius fractures in which closed reduction is not suitable:
- Joint destruction and/or subluxation visible on x-ray;
- Osteotomy and repair of distal radius malunion with or without bone graft;
- Non-displaced fractures.
- Transverse fractures of the distal radius with or without comminution (e.g. AO classifications A2 and A3);
- Transverse fractures of the distal radius with an extension into the joint with or without comminution (e.g. AO classification C2 and C1 respectively);
- Failed fracture fixation with or without bone graft for the types of fractures above;
- The above types of fractures (i.e. AO classifications non-displaced transverse, A2, A3, C1 and C2) in which reduction has been lost following fixation with percutaneous pins with or without an external fixator.
The WavEon™ WRx configuration consists of a flexible implant manufactured from stainless steel.
This 510(k) summary describes a new version of an intramedullary distal radius fixation device called WavEon™ WRx, which is an updated version of a predicate device, the Ensplint Rx. The submission primarily seeks to extend the indications for use to include C2 Distal Radius fractures.
Here's an analysis of the provided text with respect to the requested information:
1. A table of acceptance criteria and the reported device performance
| Acceptance Criteria | Reported Device Performance |
|---|---|
| Mechanical Performance: Meet requirements of ASTM 1264 | The WavEon™ WRx device meets the requirements of ASTM 1264. |
| Surgical Feasibility for C2 Fractures: Safe insertion, reduction, and fixation of C2 fractures | Cadaver studies demonstrate that the implant can be safely inserted, reduce, and fixate C2 fractures. |
2. Sample size used for the test set and the data provenance (e.g., country of origin of the data, retrospective or prospective)
The document mentions "cadaver studies" for the surgical feasibility performance data.
- Sample size: Not specified.
- Data provenance: Not specified (e.g., country of origin, retrospective/prospective).
- Test set: The "test set" would be the cadaver specimens used in the studies.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)
Not specified. The document only states "cadaver studies demonstrate." It does not mention who conducted these demonstrations or established the ground truth for "safe insertion, reduction, and fixation."
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
Not applicable/Not specified. The study described is a non-clinical cadaver study focused on the physical manipulation and fixation of the device, not an assessment of medical images or patient outcomes requiring expert adjudication in that context.
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
Not applicable. This is a medical device (intramedullary fixation) and not an AI/imaging diagnostic device. Therefore, an MRMC study related to AI assistance for human readers is not relevant to this submission.
6. If a standalone (i.e. algorithm only without human-in-the loop performance) was done
Not applicable. This is a medical device (intramedullary fixation) and not an AI/imaging diagnostic device.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)
For the mechanical performance (ASTM 1264), the ground truth is defined by the standardized test methods and acceptance criteria of ASTM 1264.
For the cadaver studies, the "ground truth" would be the physical demonstration of safe insertion, reduction, and fixation of C2 fractures as observed and assessed by the surgical team or researchers conducting the cadaveric procedures. This is an observational, procedural ground truth rather than a diagnostic one.
8. The sample size for the training set
Not applicable. This device is a physical implant, not an AI model that requires a training set.
9. How the ground truth for the training set was established
Not applicable. This device is a physical implant, not an AI model that requires a training set.

not affect safety or effectiveness. Extended indications is requested to include C2 Distal Radius fractures.
Performance Data (Non clinical)
Equivalent to the predicate, the WavEon™WVRx device meets the requirements of ASTM 1264. Further, cadaver studies demonstrate that the implant can be safely inserted, reduce and fixate C2 fractures. Therefore, the WavEon™WRx is substantially equivalent to the predicate and Safe and Effective for the extended application.

§ 888.3030 Single/multiple component metallic bone fixation appliances and accessories.
(a)
Identification. Single/multiple component metallic bone fixation appliances and accessories are devices intended to be implanted consisting of one or more metallic components and their metallic fasteners. The devices contain a plate, a nail/plate combination, or a blade/plate combination that are made of alloys, such as cobalt-chromium-molybdenum, stainless steel, and titanium, that are intended to be held in position with fasteners, such as screws and nails, or bolts, nuts, and washers. These devices are used for fixation of fractures of the proximal or distal end of long bones, such as intracapsular, intertrochanteric, intercervical, supracondylar, or condylar fractures of the femur; for fusion of a joint; or for surgical procedures that involve cutting a bone. The devices may be implanted or attached through the skin so that a pulling force (traction) may be applied to the skeletal system.(b)
Classification. Class II.
