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. The performance studies are mechanical tests.
Yes
Explanation: The device is a spinal fixation system intended to treat severe spondylolisthesis, scoliotic, or kyphotic deformities, degenerative disk disease, and fractures of the posterior thoracolumbar spine. These are conditions that impair a structure or function of the body, and the device is used to cure, mitigate, treat, or prevent these conditions.
No
Explanation: The document describes a "fixation system" used for spinal fusion and stabilization, which is a therapeutic device, not a diagnostic one. Its intended use is to treat existing conditions by providing structural support, not to identify or characterize medical conditions.
No
The device description explicitly states it consists of physical components like rods, hooks, clamps, and screws, which are hardware.
Based on the provided text, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use describes a surgical fixation system for the spine, used to treat conditions like spondylolisthesis, scoliosis, kyphosis, degenerative disk disease, and fractures. This is a therapeutic device used in vivo (within the body).
- Device Description: The device consists of physical components like rods, hooks, clamps, and screws, which are implanted into the spine.
- Lack of IVD Characteristics: There is no mention of the device being used to examine specimens derived from the human body (like blood, urine, or tissue) to provide information for diagnosis, monitoring, or compatibility testing.
Therefore, the Synthes Universal Spinal Hook, Rod and Pedicle/Sacral Screw Fixation System is a surgical implant, not an in vitro diagnostic 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.

These components were previously cleared in K951626, K951794, K962608, K963045, K963357, and K964416. This 510(k) submission is extending the region of the posterior spine in which the USS hook and rods may be used (i.e., from T8-S2 to T4-S2). In addition to these components Synthes is adding a new parallel rod connector. The connector is intended to allow a rod (3.5mm) to rod (6mm) connection with the Posterior Cervical/Thoracic Hook/Rod System. The Universal Spinal Hook, Rod, Pedicle/Sacral Screw Fixation System is indicated for the following:
When used as a posterior pedicle screw fixation system, the Synthes Universal Spinal Hook, Rod and Pedicle/Sacral Screw Fixation System is intended for patients with severe spondvlolisthesis (Grades 3 and 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; and who are having the device removed after the development of a solid fusion mass.
When used as a posterior, non-pedicle screw fixation system, the Universal Spinal Hook, Rod and Pedicle/Sacral Screw Fixation System is also intended for scoliotic, or kyphotic deformities (such as scoliosis, Schevermann's disease); degenerative disk disease (back pain of discogenic origin with degeneration of the disc confirmed by patient history and radiographic studies), and fractures of the posterior thoracolumbar spine (levels 74-S2). In addition, when using the parallel rod connector, the USS can be connected to the Posterior Cervical/Thoracic Hook/Rod System.
The overall levels of fixation are T4-S2.
