No
The document describes a mechanical spinal fixation system and does not mention any software, algorithms, or AI/ML capabilities.
No.
The device is a temporary implant system that provides immobilization and stabilization of spinal segments as an adjunct to fusion, rather than actively treating a disease or condition. It is intended to be removed after solid fusion has occurred.
No
Explanation: The "Intended Use / Indications for Use" section describes the device as a "fixation system" and "temporary implant system" used to "provide immobilization and stabilization of spinal segments as an adjunct to fusion" and "correct spinal deformity and to facilitate the biological process of spinal fusion". The "Device Description" also clarifies it's an "implant system". These descriptions indicate the device is a therapeutic and supportive device for spinal conditions, not a tool for diagnosing medical conditions.
No
The device description explicitly states that the Silhouette™ Spinal Fixation System is a "temporary implant system" consisting of "hooks and/or screws connected to rods." These are physical components made of titanium alloy, indicating it is a hardware device, not software-only.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostic devices are used to examine specimens (like blood, urine, or tissue) taken from the human body to provide information about a person's health.
- Device Description and Intended Use: The Silhouette™ Spinal Fixation System is described as a temporary implant system used to correct spinal deformity and facilitate spinal fusion. Its intended use involves surgical implantation into the spine to provide structural support and stabilization.
- Lack of Specimen Analysis: There is no mention of this device being used to analyze any biological specimens. Its function is purely mechanical and structural within the body.
Therefore, the Silhouette™ Spinal Fixation System falls under the category of a surgical implant or medical device, not an In Vitro Diagnostic.

Intended Use / Indications for Use
When used as a pedicle screw fixation system in skeletally mature patients, the Silhouette™ Spinal Fixation System is intended to provide immobilization and stahilization of spinal segments as an adjunct to fusion in the treatment of the following acute and chronic instabilities or deformities of the thoracic, lumbar, and sacral spine: degenerative spondylolisthesis with objective evidence of neurologic impairment, fracture, dislocation, scoliosis, kyphosis, spinal tumor, and failed previous fusion (pseudarthrosis).
In addition, when used as a pedicle screw fixation system, the Silhouette Spinal Fixation System is indicated for use in patients:
- a) having severe spondylolisthesis (Grade 3 and 4) at the L5-S1 joint
- b) who are receiving fusions with autogenous graft only
- c) who are having the device fixed or attached to the lumbar or sacral spine
- d) who are having the device removed after the development of a solid fusion mass
When used as a hook and sacral screw system, the Silhouette Spinal Fixation System is intended for use in the treatment of degenerative disc disease (as defined by chronic back pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies), idiopathic scoliosis, spondylolisthesis, kyphotic or lordotic deformity of the spine, loss of stability due to tumors, spinal stenosis, vertebral fracture or dislocation, pseudoarthrosis, and previous failed spinal fusion. When used for this indication, screws of the Silhouette Spinal Fixation System are intended for sacral iliac attachment only. Hook and transverse connectors of the system are intended for posterior thoracic and/or lumbar use only. As a whole, the levels of use for hook and sacral screw fixation of this system are T1 to the sacrum.

Device Description
The Silhouette™ Spinal Fixation System is a temporary implant system used to correct spinal deformity and to facilitate the biological process of spinal fusion. This system is intended for posterior use in the thoracic, lumbar, and sacral areas of the spine. Implants in this system consist of hooks and/or screws connected to rods that are intended to be removed after solid fusion has occurred. The system includes polyaxial screws of varying diameters and lengths, fixed screws of varying diameters and lengths, rods in varying lengths, hooks in varying designs, and transverse connectors in fixed and adjustable widths. All implant components are top loading and top tightening. The implants in this system are manufactured from titanium alloy (Ti-6Al-4V) that conforms to ASTM F-136.

§ 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)
