MSFX MIKRON SPINAL FIXATION SYSTEM
MSFX MIKRON SPINAL FIXATION SYSTEM is intended for use in the noncervical spine. When used as a posterior, noncervical pedicle and non- pedicle fixation system, the MSFX MIKRON SPINAL FIXATION SYSTEM is intended to provide additional support during fusion using autograft in the treatment of the treatment of the following acute and chronic instabilities or deformities:
-Degenerative disc disease (DDD) (defined as back pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies).
-Spondylolisthesis
-Trauma (i.e. fracture or dislocation)
-Spinal stenosis
- -Curvatures (i.e. scoliosis, kyphosis, and/or lordosis)
-Tumor
-Pseudoarthrosis; and failed previous fusion
Msfx Mikron System is a top-loading, multiple component, posterior spinal fixation system consisting of polyaxial pedicle screws, monoaxial pedicle screws, cannulated and spondylolisthesis screws, rods (Straight and curved) , connectors , hooks and setscrews. It allows surgeons and functions to build a spinal implant construction to stabilize and promote spinal fusion. The System components are supplied non-sterile, for single use and fabricated from titanium alloy (Ti6Al4V-EL) that conforms to ASTM F136. Various sizes of these components are available.

Mikron Spinal Fixation System
Mikron Spinal Fixation System is a pedicle screw system indicated for the treatment of severe spondylolisthesis (Grades 3 and 4) of the L5-S1 vertebra in skeletally mature patients receiving fusion by autogenous bone graft having implants attached to the lumbar and sacral spine (L3 to sacrum) with removal of the ittachment of a solid fusion.
Mikron Spinal Fixation System is also intended to provide immobilization of spinal segments in skeletally mature patients as an adjunct to fusion in the treatment of the following acute and chronic instabilities or deformities of the thoracic, lumbar and sacral spine: Degenerative spondylolisthesis with objective evidence of neurological impairment, fracture, dislocation, scoliosis, spinal tumor, and failed previous fusion (pseudarthrosis).
The Proposed Device is a top-loading multiple component, posterior spinal fixation system consisting of polyaxial pedicle screws, rods (Straight and pre-bent) and setscrews. The Mikron Spinal Fixation System will allow surgeons to build a spinal implant construct to stabilize and promote spinal fusion. The Mikron Spinal Fixation System is supplied non-sterile, single use and fabricated from titanium alloy (Ti6Al4V-ELI) that conforms to ASTM F136.
The provided text describes a 510(k) premarket notification for a medical device called the Mikron Spinal Fixation System. This type of submission primarily focuses on demonstrating "substantial equivalence" to a legally marketed predicate device, rather than proving the device meets specific performance acceptance criteria through the kind of clinical study typically associated with AI/software-as-a-medical-device (SaMD) clearances.
Therefore, the information required to answer your questions regarding acceptance criteria and performance studies for an AI/SaMD product (such as a table of accuracy, sample sizes for test/training sets, expert adjudication methods, MRMC studies, standalone performance, and ground truth establishment) is not present in this document.
This document details:
- The device's intended use (spinal fixation)
- Its material (titanium alloy)
- Its design (pedicle screws, rods, setscrews)
- Its technological characteristics compared to predicate devices
- Non-clinical performance testing: static compressive, torsion, and dynamic compressive tests according to ASTM F1717; torsion and pullout tests for screws according to ASTM F543; axial and torsional gripping capacity according to ASTM F1798; and static and dynamic 4-point bending according to ASTM F2193. These are mechanical tests to ensure the physical properties and strength of the implant, not a study of algorithm performance.
- Risk Analysis.
The key takeaway is that for a traditional hardware medical device like a spinal fixation system, "acceptance criteria" are typically met through mechanical and material testing to established industry standards (e.g., ASTM standards) and comparison to predicate devices, rather than the kind of clinical performance study with human readers and ground truth data that would be relevant for an AI/SaMD product.
In summary, the document does not contain the information needed to answer the specific questions about AI/SaMD acceptance criteria and study data.

Explanation of Acceptance Criteria: The acceptance criteria for this medical device (Mikron Spinal Fixation System) are based on demonstrating substantial equivalence to existing legally marketed predicate devices (4S Spinal System K063708 and Optima Spinal System K031585). This means the device must perform "as well as or better than" the predicate devices in the described non-clinical mechanical tests. The specific quantitative values for acceptance are not explicitly stated but are determined by successful comparison to the predicate devices under the specified ASTM standards.
2. Sample Size Used for the Test Set and Data Provenance
The provided text describes non-clinical performance testing (mechanical tests), not a clinical study involving human patients or data from patient test sets. Therefore:
- Sample size used for the test set: Not applicable in the context of human data. For mechanical testing, the sample size would refer to the number of physical device components tested for each test. This specific number is not provided in the document.
- Data provenance: Not applicable. The "data" are results from mechanical tests performed on the physical device components, not from patient populations.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts
Not applicable. This device's evaluation is based on non-clinical mechanical testing for substantial equivalence, not on interpretation of patient data by experts. Ground truth in this context would refer to objective mechanical properties rather than expert consensus on medical conditions.
4. Adjudication Method for the Test Set
Not applicable. There is no "test set" of patient data requiring adjudication. The evaluation is based on direct comparison of mechanical test results against performance of predicate devices.
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done
No. An MRMC comparative effectiveness study involves human readers interpreting cases (e.g., medical images) with and without AI assistance. This document describes a 510(k) submission for a spinal fixation system, relying on mechanical testing for substantial equivalence, not a study of AI-assisted human reading.
6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done
No. This is a physical medical device (spinal fixation system), not an algorithm or AI. Standalone performance testing typically applies to software or AI devices.
7. The Type of Ground Truth Used
The "ground truth" used is the mechanical performance and material characteristics of the legally marketed predicate devices. The Mikron Spinal Fixation System's performance is compared directly against the established performance of the 4S Spinal System (K063708) and Optima Spinal System (K031585) in rigorous laboratory mechanical tests designed to ASTM standards.
8. The Sample Size for the Training Set
Not applicable. As this is a physical medical device and not an AI/machine learning algorithm, there is no "training set."
9. How the Ground Truth for the Training Set Was Established
Not applicable. There is no training set for this type of device submission.
