The components of the Spiral Radius 90-DTM SST System are indicated for spinal fixation.
When used as an anterolateral/anterior system consisting of rods and screws, the levels of attachment are the lumbar, thoracic and cervical spine. The points of attachment and methods are screw fixation to the anterolateral vertebral bodies of the lumbar and thoracic spine (T6-L5) and the anterior vertebral bodies of the cervical spine. The Indications are degenerative disc disease defined as back pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies, spondylolisthesis, fracture, spinal stenosis, deformities (i.e., scoliosis, kyphosis, lordosis), tumor, pseudoarthrosis, or failed previous fusion (pseudoarthrosis).
When used as a nonpedicle posterior system consisting of hooks, crosslinks and sacral/iliac screws the levels of attachments are the lumbar, thoracic and cervical spine and sacrum and ilium. Intended uses include hook and sacral screw fixation to the lumbar spine, noncervical spine and to the T1-S1 spine; and hook and sacral/iliac screw fixation to the noncervical spine. The indications are degenerative disc disease defined as back pain of discogenic origin with degenerative of the disc confirmed by history and radiographic studies, spondylolisthesis, fracture, spinal stenosis, deformities (i.e., scoliosis, kyphosis, lordosis), tumors, pseudoarthrosis, or failed previous fusion (pseudoarthrosis).
When used as a pedicle screw system, in the non-cervical spine of skeletally mature patients, The Spiral Radius 90-D™ SST System is indicated for patients: (a) having severe spondylolisthesis (Grades 3 and 4) at the L5-S1 joint; (b) who are receiving fusions using autogenous bone graft only; (c) who are having the device fixed or attached to the lumbar and sacral spine (L3 and (d) who are having the device removed after the development of solid fusion mass.
In addition, when used as a pedicle screw system, in the non-cervical spine of skeletally mature patients, the Spiral Radius 90-DTM SST System is intended to provide immobilization and stabilization of spinal segments, as an adjunct to fusion, in the treatment of the following acute and chronic instabilities of the thoracic, lumbar, and sacral spine: degenerative spondylolisthesis with objective evidence of neurologic impairment, fracture, dislocation, scoliosis, spinal tumor, and failed previous fusion (pseudoarthrosis).
The Spiral Radius 90-DJM SST System consists of stainless steel rods attached to the spinal column through the use of hooks. Screws may be used to attach rods to the spinal column in certain select patients and certain select levels (See Indications). Cross-bars may be used to connect rods to provide a more rigid construct, as well as screws to rods, and hooks to rods. Screws and hooks are provided in several sizes to accommodate varying patient morphology.
The provided document is a 510(k) summary for a medical device called the "Surgical Dynamics Spiral Radius 90-DTM SST System," an orthopedic spinal fixation system.
It does not describe any acceptance criteria or studies proving the device meets those criteria in the way typically associated with performance evaluations of AI/ML or diagnostic devices. Instead, this document is a regulatory submission demonstrating substantial equivalence to a previously marketed device. This means the device is deemed safe and effective because it is similar to another legally marketed device, not through direct performance studies against specific criteria.
Therefore, most of the requested information cannot be extracted from this document, as it pertains to a different type of regulatory submission and evaluation.
Here's what can be inferred or explicitly stated based on the provided text, and what cannot be answered:
1. Table of Acceptance Criteria and Reported Device Performance:
- Cannot be provided. This document does not contain acceptance criteria for device performance (e.g., accuracy, sensitivity, specificity, or engineering performance metrics with thresholds). It is a substantial equivalence claim, not a performance study report.
2. Sample Size Used for the Test Set and Data Provenance:
- Cannot be provided. There is no "test set" in the context of this 510(k) submission. The substantial equivalence claim relies on comparing the new device to a predicate device, not on testing the device against a defined dataset of patients/cases.
3. Number of Experts Used to Establish Ground Truth and Their Qualifications:
- Cannot be provided. Since there's no test set or performance evaluation against a ground truth, there were no experts used in this capacity.
4. Adjudication Method:
- Cannot be provided. Not applicable due to the reasons above.
5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study:
- Cannot be provided. There is no mention of an MRMC study. This type of study is common for diagnostic devices where human reader performance is being evaluated, often with or without AI assistance, which is not the subject of this 510(k) submission.
6. Standalone Performance Study (Algorithm Only):
- Cannot be provided. This document is for a mechanical spinal fixation system, not an algorithm or AI-driven device. Therefore, a "standalone algorithm performance" study is not relevant.
7. Type of Ground Truth Used:
- Cannot be provided. Not applicable. The "ground truth" for this submission is the established safety and effectiveness of the predicate device to which the Spiral Radius 90-D™ SST System is compared.
8. Sample Size for the Training Set:
- Cannot be provided. This device is hardware; it does not involve training data or algorithms in the context of this 510(k) submission.
9. How Ground Truth for the Training Set Was Established:
- Cannot be provided. Not applicable.
Summary based on the document:
This 510(k) submission (K021825) outlines the Surgical Dynamics Spiral Radius 90-DTM SST System, a spinal fixation system consisting of rods, screws, hooks, and cross-bars. The device's components, indicated uses (anterolateral/anterior, nonpedicle posterior, and pedicle screw systems for various spinal segments and conditions), and the claim of substantial equivalence to an existing marketed device are described. This regulatory pathway means that the device's safety and effectiveness are established by its similarity to a legally marketed predicate device, rather than through independent studies evaluating specific performance criteria against a ground truth.
Key takeaway for your request: This document is not the type that would contain the specific performance metrics, study designs, and ground truth information you're asking for, as it's a "substantial equivalence" claim for a hardware device, not a performance study report for a diagnostic or AI-enabled device.

§ 888.3050 Spinal interlaminal fixation orthosis.
(a)
Identification. A spinal interlaminal fixation orthosis is a device intended to be implanted made of an alloy, such as stainless steel, that consists of various hooks and a posteriorly placed compression or distraction rod. The device is implanted, usually across three adjacent vertebrae, to straighten and immobilize the spine to allow bone grafts to unite and fuse the vertebrae together. The device is used primarily in the treatment of scoliosis (a lateral curvature of the spine), but it also may be used in the treatment of fracture or dislocation of the spine, grades 3 and 4 of spondylolisthesis (a dislocation of the spinal column), and lower back syndrome.(b)
Classification. Class II.
