The C-Wires are single use devices. They are intended to be used by trained professionals for the purpose of bone fracture fixation. The C-Wires should only be used with wire drivers that are designed to drive wires having longitudinal flats.
The C-Wire Double Ended Orthopedic Wires are single-use devices that are indicated for surgical repair of small bone trauma. The C-Wires provide mechanical stability during the natural bone healing process. Each wire is 5" (127mm) long, with each end ground to either a spade or trocar shaped tip. C-Wires are available in four different diameters (0.7mm, 0.89mm, 1.14mm and 1.57mm). The wires are made of 316LVM stainless steel.
The provided document describes the CONMED Corporation's C-Wire Double Ended Orthopedic Wires and its substantial equivalence to a predicate device (SMT Schilling Kirschner/Guide Wires, K100736). As such, this document does not contain information about acceptance criteria and a study proving a new device meets those acceptance criteria in the typical sense of a performance study for, for example, an AI/ML device.
Instead, the submission argues for substantial equivalence based on:
- Long-term market history: The device has been in continuous use for 38 years with few complaints. This serves as a form of "real-world evidence" demonstrating safety and effectiveness over a very long period.
- Similarity to predicate devices: The C-Wire is very similar to other FDA-cleared wires in terms of intended use, engineering drawings, material, method of operation, and shape/size.
- Conformance to FDA standards: The device conforms to FDA standards related to pins and wires and other recognized standards.
- Completed testing: Transportation, biocompatibility, sterilization, and shelf-life testing were completed.
Therefore, the requested information elements related to acceptance criteria, specific performance metrics, sample sizes for test/training sets, ground truth establishment, expert involvement, and MRMC studies are not applicable or cannot be extracted from this document, as it pertains to a traditional medical device demonstrating substantial equivalence rather than a diagnostic device relying on specific performance metrics established through a clinical or algorithmic study.
However, I can extract the information that is present and indicate where requested information is not available.
Description of the Acceptance Criteria and the Study that Proves the Device Meets the Acceptance Criteria:
The C-Wire Double Ended Orthopedic Wires are demonstrated to be substantially equivalent to the predicate device, SMT Schilling Kirschner/Guide Wires (K100736). The "acceptance criteria" in this context are not quantitative performance metrics of a novel diagnostic algorithm, but rather the qualitative and quantitative similarities to the predicate device, along with a long history of safe use and compliance with relevant standards. The "study" proving the device meets these criteria is a substantial equivalence comparison and a review of post-market surveillance data.
1. A table of acceptance criteria and the reported device performance

2. Sample size used for the test set and the data provenance:
- Sample Size for Test Set: Not applicable in the context of a traditional device substantial equivalence based on long market history and comparison to a predicate device. Performance is not measured on a specific test set of cases. The "test" is the comparison analysis and the review of 38 years of post-market surveillance.
- Data Provenance: The 38 years of "continuous use" and "Post Market Surveillance Reports" indicate retrospective real-world data, likely from various unspecified regions where the device was marketed.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:
- Experts and Qualifications: Not applicable. Ground truth in the context of diagnostic AI/ML evaluation is not relevant here. The evidence for substantial equivalence relies on device design, materials, manufacturing controls, and historical safety data.
4. Adjudication method for the test set:
- Adjudication Method: Not applicable. No "test set" in the traditional sense, and thus no adjudication of expert interpretations for ground truth.
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:
- MRMC Study: Not applicable. This document is for a physical medical device (orthopedic wires), not an AI/ML diagnostic system. No human readers or AI assistance are involved in its primary function.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:
- Standalone Performance Study: Not applicable. This is not an algorithm.
7. The type of ground truth used:
- Type of Ground Truth: In this context, the "ground truth" for the safety and effectiveness claim is primarily based on:
- Historical Performance/Outcomes Data: 38 years of continuous use with few complaints from post-market surveillance.
- Engineering and Material Standards: Conformance to established FDA and recognized standards for physical properties, device design, and biocompatibility.
- Direct Comparison to Predicate: Demonstrating substantial equivalence in design, materials, intended use, and technology to a legally marketed device.
8. The sample size for the training set:
- Sample Size for Training Set: Not applicable. This is not an AI/ML device that requires a training set.
9. How the ground truth for the training set was established:
- Ground Truth for Training Set: Not applicable. This is not an AI/ML device.
