Mg OSTEOINJECT™ is intended for bony voids or defects of the extremities and pelvis that are not intrinsic to the stability of the bony structure. These defects may be surgically created osseous defects or osseous defects created by traumatic injury to the bone. Mg OSTEOINJECT™ can be used as an adjunct to conventional rigid hardware fixation by supporting the bone fragments during the surgical procedure only in the extremities and pelvis. Once the material has set, it acts as a temporary support medium and is not intended to provide structural support during the healing process. Mg OSTEOINJECT™ is intended to be placed into bony voids either before or after final fixation. Mg OSTEOINJECT™ is resorbed and replaced with bone during the healing process. Mg OSTEOINJECT™ is not intended to treat large defects that in the surgeon's opinion would fail to heal spontaneously.
Mg OSTEOINJECT™ is a magnesium-based synthetic bone void filler that is drillable, resorbable, radiopaque, and osteoconductive. The Mg OSTEOINJECT™ Kit contains powder (magnesium-based compound) and a mixing solution (buffered saline). Once the components are mixed intra-operatively prior to implantation, an acid-base reaction happens to form a cohesive paste. Once the product is placed into the bony void, the paste will adhere to the adjacent bone during the curing process. The device is provided sterile to the end user for single-use only in two sizes, 3 cc and 5 cc.
The provided text describes the 510(k) premarket notification for the Mg OSTEOINJECT™ device. This is a medical device submission, and the content primarily focuses on demonstrating substantial equivalence to existing predicate devices, rather than establishing performance against specific acceptance criteria through a clinical study or AI model evaluation.
Therefore, the information required to populate the requested table and answer the study-related questions (sample size, expert qualifications, adjudication, MRMC, standalone performance, ground truth, training set details) is not present in the provided document. The document explicitly states:
"No clinical data were included in this submission." (Page 4, under "PERFORMANCE DATA")
The performance data mentioned ("Non-clinical testing data... referenced from K212991") pertain to:
- Chemical composition
- Physical properties
- Sterilization
- Sterile barrier shelf life
- Product shelf life
- Biocompatibility
- Drillability
- LAL testing for bacterial endotoxins
These are all non-clinical tests assessing the physical characteristics, safety, and sterility of the device, and are not related to an AI model's performance on medical images or clinical outcomes.
Based on the provided text, here's what can be stated:
1. A table of acceptance criteria and the reported device performance:
Since this is a 510(k) submission for a bone void filler and not an AI/imaging device requiring performance metrics like sensitivity/specificity, there are no "acceptance criteria" in the traditional sense of an AI model's performance on a test set. The acceptance here is based on substantial equivalence to a predicate device.
The document highlights the following characteristics that demonstrate equivalence, acting as de-facto "performance" attributes:
| Feature / Comparison | Acceptance Criteria (Implied by Predicate Equivalence) | Reported Device Performance (as per submission) |
|---|---|---|
| Composition (Mineral Components) | Identical to K212991 Predicate | β-tricalcium phosphate (8%), Magnesium oxide (41%), Monopotassium phosphate (44%), Monosodium phosphate (3%) |
| Material Form (Before setting) | Powder and liquid components | Powder and liquid components |
| Post-mixing/setting Properties | Injectable, sets in surgical site, cohesive paste | Injectable, sets in surgical site, cohesive paste |
| Porosity/Granule Size (after setting) | Non-porous solid | Not applicable, non-porous solid |
| Scaffold/Binder | None | None |
| Radiopacity | Not explicitly stated as a criterion, but mentioned if relevant for clinical use | Mentioned as "radiopaque" in device description |
| Resorbability | Resorbed and replaced with bone during healing process | Resorbed and replaced with bone during healing process |
| Drillability | Demonstrated in predicate testing (referenced) | Demonstrated in predicate testing (referenced) |
| Adjunct to hardware fixation | Can be used as adjunct | Can be used as adjunct |
| Sterility | Provided sterile | Provided sterile |
| Sterilization Method | Gamma irradiation | Gamma irradiation |
| Usage | Single-patient, single-use | Single-patient, single-use |
| Bacterial Endotoxin Limit | ≤ 20 EU/device (for implanted devices) | Met the limit acceptance criterion (≤ 20 EU/device) |
| Non-clinical performance | Met standards demonstrated by predicate | Chemical composition, physical properties, sterilization, sterile barrier shelf life, product shelf life, and biocompatibility demonstrated to be equivalent. |
2. Sample size used for the test set and the data provenance:
- Not applicable. No clinical test set data was included. The performance details are based on non-clinical testing and comparison to a predicate device.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:
- Not applicable. No clinical ground truth was established for this submission.
4. Adjudication method for the test set:
- Not applicable. No clinical test set was evaluated.
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 device is a bone void filler, not an AI diagnostic/imaging assistance tool.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:
- Not applicable. This is a physical medical device, not an algorithm.
7. The type of ground truth used:
- Not applicable. No clinical ground truth was established. Performance demonstration relies on non-clinical testing results and substantial equivalence to a predicate device's established safety and effectiveness.
8. The sample size for the training set:
- Not applicable. There is no "training set" as this is not an AI/machine learning product.
9. How the ground truth for the training set was established:
- Not applicable. There is no "training set" for this device.

EQUIVALENCE TO MARKETED DEVICES
The subject device is substantially equivalent in indications and design principles to the primary predicate device K212991 and the reference device K140375. Provided at the end of this summary is a table comparing the Indications for Use Statements and the technological characteristics of the subject device and the primary predicate device.
The primary predicate device is K212991, for the identical formulation, packaging, and sterilization as the subject device. The subject device differs from K212991 in terms of the indications for use; the subject device is indicated only for use in the extremities and pelvis.
The reference device K140375 is for support of substantial equivalence of the subject device provided in a kit with a volume of 3 cc. The reference device K140375 includes the same indications for use in the extremities and pelvis and includes a range of volumes from 0.75 cc to 9 cc.
The subject device and the primary predicate device K21299 have the same intended use, the same product classification and product codes (MQV and OIS), and have similar Indications for Use statements. The subject device, the primary predicate device, and the reference device are indicated for use as bone void fillers in the extremities and pelvis. Although the subject device, the primary predicate device, and the reference device have slightly different Indications for Use language, these differences in language do not change the intended use as a bone void filler.
The subject device, the primary predicate device, and the reference device all incorporate calcium phosphate materials that are mixed to form a solid after setting (subject device and primary predicate device) or are within a polymeric binder or scaffold (reference device). The subject device and primary predicate device have identical materials and formulation and are mixed intra-operatively. The subject device, the primary predicate device, and the reference device are all provided in comparable volumes, sterilized by irradiation, and are for single-patient, single-use.
Differences among the subject device, the primary predicate device, and the reference device include the exact indications for use (including use in the posterolateral spine for the primary predicate and reference device), the mineral components, and the scaffold or binder material (bovine collagen in the reference device K 140375). The minor differences among the subject device, the primary predicate device, and the reference device do not raise new issues of safety or effectiveness, and therefore, do not impact substantial equivalence.
CONCLUSION
The subject device, the primary predicate device, and the reference device have the same intended use, have similar technological characteristics, and are made of similar materials. The subject device and the primary predicate device are manufactured from identical materials. The subject device, the primary predicate, and the reference device encompass the same range of physical dimensions (volumes), are packaged in similar materials and are sterilized using similar methods. The data included in this submission demonstrate substantial equivalence to the predicate device and the reference device listed above.
