The JAZZ Spinal System is intended for posterior, non - cervical fixation as an adjunct to fusion for skeletally mature patients for the following indications: degenerative disc disease (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; pseudarthrosis; and/or failed previous fusion. In addition, when used as a pedicle screw fixation system, the JAZZ Spinal System is intended for skeletally mature patients with severe spondylolisthesis (Grades 3 and 4) of the fifth lumbar-first sacral, L5-S1 vertebra, who are receiving fusion by autogenous bone graft only, who are having the device attached to the lumbar and sacral spine (levels may be from L3 to the sacrum/ilium), who are having the device removed after the attainment of a solid fusion.

The JAZZ Spinal System consists of a variety of shapes and sizes of screws and rods that can be rigidly locked in a variety of configurations, with each construct being tailor-made for the individual case. Fixation is provided via a posterior approach. The components are made from titanium alloy, unalloyed titanium, or cobalt chrome alloy. Implant components of the system include straight and pre-bent rods, monoaxial and polyaxial screws, reduction screws, domino connectors, crosslinks, dual headed screws and connectors, transverse and sagittal uniplanar screws, favored angle screws, modular screws, iliac screws, along with associated set screws.

The provided FDA 510(k) clearance letter for the JAZZ Spinal System does not describe a study related to AI/algorithm performance for a diagnostic or imaging device. Instead, it details a clearance for a medical implant device (Thoracolumbosacral Pedicle Screw System).

Therefore, I cannot extract the information requested about acceptance criteria, study design, ground truth establishment, or human-in-the-loop performance related to an AI/algorithm. The document focuses on the mechanical performance and material safety of the spinal implant.

Specifically:

• Acceptance Criteria & Reported Performance (Table): Not applicable for an AI/algorithm study based on this document. The document mentions "Performance testing" for the spinal implant, including "static compression bending, static torsion, and dynamic compression bending per ASTM F1717-21, as well as static neutral angle dissociation and static maximum angle dissociation per ASTM F1798-13." However, these are mechanical tests for the implant itself, not metrics for an AI's diagnostic performance.
• Sample size and data provenance, number of experts, adjudication, MRMC study, standalone performance, type of ground truth, training set size and ground truth: None of this information is present in the document because it pertains to the validation of a software algorithm or AI, not a spinal implant. The "ground truth" for a spinal implant would be its material properties and mechanical integrity, tested in a lab setting, not clinical annotation by experts.

In summary, the provided document is irrelevant to the prompt's request for details on an AI/algorithm performance study.

This FDA 510(k) clearance letter pertains to a spinal fixation system, which is a medical device, not an AI/software device. Therefore, the provided text does not contain the information needed to answer the questions about AI/software device acceptance criteria and study details (such as sample size, ground truth expert qualifications, MRMC studies, standalone performance, training set details, etc.).

In order to achieve additional levels of fixation, the Momentum Posterior Spinal Fixation System can also be connected to the Cortium® Universal OCT Spinal Fixation System or neon3® universal OCT spinal stabilization system via transition rods or connectors. Please refer to the Cortium or neon3 Instructions for Use for a list of indications for use.

The Momentum® Posterior Spinal Fixation System is a standard pedicle screw and rod systems designed for fixation and correction in the thoracolumbar and sacroiliac spine. This 510(k) submission adds hooks, various connectors, and monoaxial screws to the previously cleared system from K231809 and K191932.

The subject hooks are intended to provide deformity correction according to patient anatomical needs. The subject connectors are intended to provide additional options to improve stability. The subject monoaxial fenestrated screws are identical below the tulip to the previously cleared fenestrated screws with the addition of the option to use G21 V-Steady bone cement. The Momentum® Posterior Spinal Fixation System is manufactured from titanium alloy Ti-6Al-4V ELI per ASTM F136 and ISO 5832-3 and cobalt chromium Co-Cr-28Mo per ASTM F1537 and ISO 5832-12.

This document is a 510(k) premarket notification decision letter for a medical device called the "Momentum® Posterior Spinal Fixation System." It does not contain information about acceptance criteria or a study proving the device meets those criteria in the context of an AI/ML powered device.

The letter simply states that the FDA has reviewed the submission and determined the device to be "substantially equivalent" to legally marketed predicate devices. This determination is based on a comparison of the device's indications for use, technological characteristics, and performance data (mechanical strength testing results) to existing predicate devices.

Therefore, I cannot fulfill your request for the specific information regarding acceptance criteria and study data for an AI/ML powered device based solely on the provided text. The document concerns a traditional implantable medical device, not an AI/ML product.

To reiterate, the provided text does not contain any of the following information:

1. A table of acceptance criteria and the reported device performance: Not applicable, as this is not an AI/ML device with performance metrics like sensitivity, specificity, etc.
2. Sample sizes used for the test set and the data provenance: Not applicable for an AI/ML model. The "test set" here refers to mechanical testing of physical components, not a data-driven model.
3. Number of experts used to establish the ground truth...: Not applicable, as ground truth is not established in the context of an AI/ML model for this device.
4. Adjudication method: Not applicable.
5. Multi-reader multi-case (MRMC) comparative effectiveness study: Not applicable.
6. Standalone (i.e. algorithm only without human-in-the-loop performance) was done: Not applicable.
7. The type of ground truth used: Not applicable.
8. The sample size for the training set: Not applicable.
9. How the ground truth for the training set was established: Not applicable.

The performance data mentioned (ASTM F1717 Dynamic Compression Bending) refers to mechanical testing of the spinal fixation system components to ensure their structural integrity and durability, not the performance of an AI/ML algorithm.
