The OutologousTM Spinal Fixation System is a pedicle screw fixation system indicated for the treatment of severe spondylolisthesis (Grade 3 and Grade 4) of the LS-S1 vertebra in skeletally mature patients receiving fusion by autogenous bone grafting having implants attached to the lumbar and sacral spine with removal of implants after the attainment of a solid fusion.
In addition, the Outologous Spinal Fixation System is intended to provide immobilization and stabilization of the 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 spines: degenerative spondylolisthesis with objective evidence of neurological impairment, fracture of the vertebral body, dislocation, scoliosis, kyphosis, spinal tumor, and failed fusions (pseudoarthrosis).
Not Found
This looks like a 510(k) summary for a medical device called the "Outologous Spinal Fixation System." This type of document is for proving substantial equivalence to a predicate device, not for proving the device meets specific acceptance criteria through a clinical study with performance metrics in the way a novel AI algorithm might.
Therefore, the requested information about acceptance criteria, study design, ground truth, and expert adjudication as typically applied to performance claims of AI/ML devices is not present in this document. The document primarily focuses on regulatory classification, intended use, and the FDA's marketing clearance.
Here's a breakdown of why the requested information cannot be extracted from the provided text according to the specific prompt questions:
-
A table of acceptance criteria and the reported device performance: This document does not describe performance metrics or acceptance criteria in the sense of a clinical trial for efficacy or diagnostic accuracy. It's about demonstrating substantial equivalence structurally and functionally to existing devices.
-
Sample size used for the test set and the data provenance: Not applicable. There is no specific "test set" for performance evaluation in this context. The demonstration of substantial equivalence relies on design, material, and mechanical testing, but not on clinical performance data in the way an AI algorithm would.
-
Number of experts used to establish the ground truth for the test set and the qualifications of those experts: Not applicable. Ground truth for clinical performance is not established or reported in this type of submission.
-
Adjudication method (e.g., 2+1, 3+1, none) for the test set: Not applicable.
-
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 is a spinal fixation system, not an AI-assisted diagnostic tool.
-
If a standalone (i.e., algorithm only without human-in-the-loop performance) was done: Not applicable.
-
The type of ground truth used (expert consensus, pathology, outcomes data, etc.): Not applicable.
-
The sample size for the training set: Not applicable. There is no "training set" for an AI algorithm.
-
How the ground truth for the training set was established: Not applicable.
In summary, this document is a regulatory clearance for a physical medical device (spinal fixation system) based on substantial equivalence, and therefore the types of studies and performance metrics typically associated with AI/ML-based diagnostic devices (which your questions are geared towards) are not relevant or reported here.

§ 888.3070 Thoracolumbosacral pedicle screw system.
(a)
Identification. (1) Rigid pedicle screw systems are comprised of multiple components, made from a variety of materials that allow the surgeon to build an implant system to fit the patient's anatomical and physiological requirements. Such a spinal implant assembly consists of a combination of screws, longitudinal members (e.g., plates, rods including dual diameter rods, plate/rod combinations), transverse or cross connectors, and interconnection mechanisms (e.g., rod-to-rod connectors, offset connectors).(2) Semi-rigid systems are defined as systems that contain one or more of the following features (including but not limited to): Non-uniform longitudinal elements, or features that allow more motion or flexibility compared to rigid systems.
(b)
Classification. (1) Class II (special controls), when intended to provide immobilization and stabilization 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: severe spondylolisthesis (grades 3 and 4) of the L5-S1 vertebra; degenerative spondylolisthesis with objective evidence of neurologic impairment; fracture; dislocation; scoliosis; kyphosis; spinal tumor; and failed previous fusion (pseudarthrosis). These pedicle screw spinal systems must comply with the following special controls:(i) Compliance with material standards;
(ii) Compliance with mechanical testing standards;
(iii) Compliance with biocompatibility standards; and
(iv) Labeling that contains these two statements in addition to other appropriate labeling information:
“Warning: The safety and effectiveness of pedicle screw spinal systems have been established only for spinal conditions with significant mechanical instability or deformity requiring fusion with instrumentation. These conditions are significant mechanical instability or deformity of the thoracic, lumbar, and sacral spine secondary to severe spondylolisthesis (grades 3 and 4) of the L5-S1 vertebra, degenerative spondylolisthesis with objective evidence of neurologic impairment, fracture, dislocation, scoliosis, kyphosis, spinal tumor, and failed previous fusion (pseudarthrosis). The safety and effectiveness of these devices for any other conditions are unknown.”
“Precaution: The implantation of pedicle screw spinal systems should be performed only by experienced spinal surgeons with specific training in the use of this pedicle screw spinal system because this is a technically demanding procedure presenting a risk of serious injury to the patient.”
(2) Class II (special controls), when a rigid pedicle screw system is intended to provide immobilization and stabilization of spinal segments in the thoracic, lumbar, and sacral spine as an adjunct to fusion in the treatment of degenerative disc disease and spondylolisthesis other than either severe spondylolisthesis (grades 3 and 4) at L5-S1 or degenerative spondylolisthesis with objective evidence of neurologic impairment. These pedicle screw systems must comply with the following special controls:
(i) The design characteristics of the device, including engineering schematics, must ensure that the geometry and material composition are consistent with the intended use.
(ii) Non-clinical performance testing must demonstrate the mechanical function and durability of the implant.
(iii) Device components must be demonstrated to be biocompatible.
(iv) Validation testing must demonstrate the cleanliness and sterility of, or the ability to clean and sterilize, the device components and device-specific instruments.
(v) Labeling must include the following:
(A) A clear description of the technological features of the device including identification of device materials and the principles of device operation;
(B) Intended use and indications for use, including levels of fixation;
(C) Identification of magnetic resonance (MR) compatibility status;
(D) Cleaning and sterilization instructions for devices and instruments that are provided non-sterile to the end user; and
(E) Detailed instructions of each surgical step, including device removal.
(3) Class II (special controls), when a semi-rigid system is intended to provide immobilization and stabilization of spinal segments in the thoracic, lumbar, and sacral spine as an adjunct to fusion for any indication. In addition to complying with the special controls in paragraphs (b)(2)(i) through (v) of this section, these pedicle screw systems must comply with the following special controls:
(i) Demonstration that clinical performance characteristics of the device support the intended use of the product, including assessment of fusion compared to a clinically acceptable fusion rate.
(ii) Semi-rigid systems marketed prior to the effective date of this reclassification must submit an amendment to their previously cleared premarket notification (510(k)) demonstrating compliance with the special controls in paragraphs (b)(2)(i) through (v) and paragraph (b)(3)(i) of this section.
