The Stainless Steel Spinal System is a non-cervical spinal fixation device intended for use as a posterior pedicle screw fixation system (T1-S2/ilium), a posterior non-pedicle screw fixation system (T1-L5), or as an anterolateral fixation system (T8-L5). Pedicle screw fixation is limited to skeletally mature patients. The device is indicated as an adjunct to fusion for the following indications: degenerative disc disease (defined as discogenic back pain with degeneration of the disc confirmed by history and radiographic studies), spondylolisthesis, trauma (i.e., fracture or dislocation), spinal stenosis, deformities or curvatures (i.e., scoliosis, kyphosis, and/or lordosis), tumor, pseudoarthrosis, and failed previous fusion.

The Stainless Steel Spinal System consists of a variety of shapes and sizes of screws, rods, hooks, and cross-connectors. The Stainless Steel Spinal System components can be rigidly locked together creating a rigid construct for promoting fusion. The individual implant components are fabricated from medical grade stainless steel alloy 316 LVM described by such standards as ASTM F-138 and ISO 5832-1.

Here's a summary of the acceptance criteria and study information for the Stainless Steel Spinal System (K100970) based on the provided text, formatted to address your specific points:

Since the provided text describes a spinal implant system and its mechanical testing, not a diagnostic AI device, many of the requested fields (e.g., sample size for test set, number of experts, adjudication method, MRMC study, standalone performance, training set details) are not applicable. I will specify "N/A" for these fields.

Acceptance Criteria and Device Performance for Stainless Steel Spinal System (K100970)

1. Table of Acceptance Criteria and Reported Device Performance

Note: The document explicitly states "The construct performed as designed and met or exceeded all product specifications." This implies that the specific numerical criteria were met, but the exact numerical thresholds for "product specifications" and the measured performance values are not detailed in this summary.

2. Sample size used for the test set and the data provenance

• Sample Size for Test Set: Not specified. (The study involves mechanical testing of device constructs, not data from human subjects or images.)
• Data Provenance: N/A (Mechanical tests are conducted on manufactured devices, not patient data.)

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts

• Number of Experts: N/A (Ground truth for mechanical performance is established by engineering standards and test results, not expert consensus.)
• Qualifications of Experts: N/A

4. Adjudication method (e.g. 2+1, 3+1, none) for the test set

• Adjudication Method: N/A (Not relevant for mechanical testing.)

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: No, this is not an AI/diagnostic device.

6. If a standalone (i.e. algorithm only without human-in-the loop performance) was done

• Standalone Performance: No, this is not an AI/diagnostic device.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.)

• Type of Ground Truth: Engineering standards and design specifications as defined by ASTM F-1717.

8. The sample size for the training set

• Sample Size for Training Set: N/A (This is not an AI/machine learning device that requires a training set.)

9. How the ground truth for the training set was established

• Ground Truth for Training Set: N/A

Study Summary:

The study conducted for the Stainless Steel Spinal System involved mechanical testing to demonstrate its performance and substantial equivalence to predicate devices. The tests performed were:

• Static axial compression
• Static torsion
• Dynamic axial compression

These tests were performed in accordance with ASTM F-1717. The results indicated that the device performed as designed and met or exceeded all specified product requirements, supporting its substantial equivalence to the predicate devices.
