The document describes a mechanical spinal fixation system and its components, with no mention of software, algorithms, or any technology related to AI or ML.
Yes
The device is a spinal fixation system intended to treat various spinal conditions like scoliosis, kyphosis, and spinal fractures, which are medical conditions, thus making it a therapeutic device.
No
Explanation: The SSCS is described as a "spinal fixation device" and "spinal fixation system" used for instrumentation and stabilization of the spine, not for diagnosing conditions. Its intended use is to treat various spinal conditions by providing stability and correction.
No
The device description explicitly states it is a spinal fixation system comprised of various types and sizes of components that are implanted via a posterior surgical approach, including bone screws, longitudinal rods, and optional transverse connecting elements. This describes physical hardware, not software.
Based on the provided text, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are medical devices used to perform tests on samples taken from the human body (like blood, urine, tissue) to provide information about a person's health.
- Device Description: The SSCS is described as a "spinal fixation system comprised of various types and sizes of components... that are implanted via a posterior surgical approach and assembled to create a spinal construct." This clearly indicates a device that is surgically implanted into the body, not used to test samples from the body.
- Intended Use: The intended use describes the conditions for which the device is used as a posterior spinal fixation device (scoliosis, kyphosis, fractures, etc.). This is a therapeutic use, not a diagnostic one.
- Lack of IVD Characteristics: The text does not mention any testing of biological samples, analysis of biomarkers, or any other activities associated with in vitro diagnostics.
Therefore, the SSCS is a surgical implant, not an IVD.

Intended Use / Indications for Use
The Segmental Spinal Correction System (SSCS), including the SSCS Hinged Screw, is intended for use as a posterior spinal fixation device to aid in the surgical correction of various spinal deformities and pathologies in the thoraco-lumbo-sacral portion of the spine. It is intended to provide stabilization during the development of fusion utilizing a bone graft. Specific indications for the SSCS are dependent in part on the configuration of the assembled device as described below.
When used as a thoracic/lumbar hook or sacral screw and hook system, the SSCS is intended for instrumentation of the spine at levels ranging from T1 to S2 and is indicated for:
- scoliosis
- kyphosis
- spinal fractures
- degenerative disc disease (defined as back pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies).
- tumors
- stenosis
- spondylolisthesis
- pseudoarthrosis
- previously failed attempts at spinal fusion
When used as a sacral/pedicle screw system, the SSCS is intended for patients:
-
- Having severe spondylolisthesis (grade 3 or 4) of the fifth lumbar-first sacral (LS-S1) vertebral joint
-
- Who are receiving fusions using autogenous bone graft only.
-
- Who are having the device fixed or attached to the lumbar and sacral spine.
-
- Who are having the device removed after the development of a solid fusion mass.
Although the levels of fusion may not go above the L5-S1 joint, the SSCS screws may be inserted into pedicles up to, but not above, L-3.

§ 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.

6. Technical Comparison
The SSCS, with the addition of the Hinged Screws, is similar to the previously cleared SSCS that included Rigid Screws (K955173) and to other predicate devices in terms of its design, technical characteristics, and materials. These devices consist of several basic types and various sizes of implantable components including longitudinal rods, bone screws, and transverse connectors that are assembled to create a spinal construct.
The SSCS Hinged Screws, like the SSCS Rigid Screws and the bone screws of other predicate spinal systems serve as anchoring elements to attach the device to the spine. In all of these devices, bilaterally placed rods, the longitudinal elements of the spinal system constructs, are attached to the heads of the implanted screws.
The SSCS Hinged Screw shares many of the same design, dimensional and material characteristics as the SSCS Rigid Screw and employs the same interconnection mechanism for attachment of the screw to the rod. The distinguishing feature of the SSCS Hinged Screw compared to the SSCS Rigid Screw is the existence of a hinged connection between the screw head and shaft, as opposed to the Rigid Screw in which the head and shaft are solidly joined.
7. Performance Data
Mechanical testing of SSCS Hinged Screw constructs was performed in accordance with the ASTM Provisional Standard for testing spinal implant devices. The results of this testing demonstrated that the mechanical performance characteristics (bendingcompression static strength and stiffness, torsional stiffness and fatigue strength) of SSCS Hinged Screw constructs are at least comparable to, if not better than, those of SSCS Rigid Screw constructs and/or other predicate devices.

regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 895. A substantially equivalent determination assumes compliance with the Good Manufacturing Practice for Medical Devices: General (GMP) regulation (21 CFR Part 820) and that, through periodic GMP inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal Laws or Regulations.
FDA advises that the use of your device system with any other device components but those identified in this 510(k) would require submission of a new 510(k) providing documentation of design, material, and labeling compatibility between the device components. Mechanical testing of a spinal system consisting of the subject device components and other device components, whether yours or those of other manufacturers, may also be required.
This letter will allow you to begin marketing your device as described in your 510(k) premarket notification immediately. An FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and permits your device to proceed to the market.
If you desire specific advice for your device on our labeling regulation (21.CFR.
