The device description and performance studies focus on the mechanical properties and structural integrity of a bone screw and rod construct for spinal fixation. There is no mention of software, algorithms, or data processing that would indicate the use of AI or ML.
Yes
The device is described as an "adjunct to fusion" and is intended to address various medical conditions such as "traumatic spinal fractures and/or traumatic dislocations; instability or deformity; failed previous fusions (e.g., pseudarthrosis); tumors involving the cervical spine; and degenerative disease." These are all therapeutic applications.
No
The PMT Posterior Fixation System is a medical implant (bone screw and rod construct) used for spinal fixation, not for diagnosing medical conditions. Its function is to provide immobilization and support as an adjunct to fusion or to restore spinal column integrity.
No
The device description clearly states it is a bone screw and rod construct made of titanium alloy, which are physical hardware components.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly describes a device used in vivo (within the body) for the surgical fixation of the spine. IVDs are used in vitro (outside the body) to examine specimens from the human body to provide information for diagnosis, monitoring, or screening.
- Device Description: The device is described as a bone screw and rod construct, which is a surgical implant. IVDs are typically reagents, instruments, or systems used to perform tests on biological samples.
- Lack of IVD Characteristics: There is no mention of analyzing biological samples, performing tests, or providing diagnostic information based on laboratory analysis.
Therefore, the PMT Posterior Fixation System is a surgical implant, not an In Vitro Diagnostic device.

Intended Use / Indications for Use
The PMT Posterior Fixation System is intended to provide immobilization of spinal segments as an adjunct to fusion for the following acute and chronic instabilities of the cervical spine (C1 to C7) and the thoracic spine from T1 to T3: traumatic spinal fractures and/or traumatic dislocations; instability or deformity; failed previous fusions (e.g., pseudarthrosis); tumors involving the cervical spine; and degenerative disease, including intractable radiculopathy and/or myelopathy, neck and/or arm pain of discogenic origin as confirmed by radiographic studies, and degenerative disease of the facets with instability.
The PMT Posterior Fixation System is also intended to restore the integrity of the spinal column even in the absence of fusion for a limited time period in patients with advanced stage tumors involving the cervical spine in whom life expectancy is of insufficient duration to permit achievement of fusion.

Device Description
The PMT Posterior Fixation System is a bone screw and rod construct that will be supplied sterile and single use only. It consists of polyaxial screws, fixation rods, and locking set screws. The polyaxial screws are designed to be utilized for pedicle fixation or anchored to the posterior lateral mass of the cervical (C1 to C7) and thoracic (T1 to T3) vertebra. A set screw is used to connect and anchor the rod to each screw head while locking the orientation of the polyaxial screw.
The PMT Posterior Fixation System is manufactured from 6Al-4V Titanium Alloy, conforming to ASTM F136. The polyaxial screw, available in diameters of 3.5mm and 4.0mm, is self-tapping with a range of screw lengths between 8mm to 24mm. The rod is offered in two diameters, 3.5mm and 3.8mm, with a range in lengths of 15mm to 240mm. The screw head that is assembled to the polyaxial screw accepts the 3.5mm or 3.8mm rod. The set screw comes in one size and has a matching thread profile to the screw head.

§ 888.3075 Posterior cervical screw system.
(a)
Identification. Posterior cervical screw systems are comprised of multiple, interconnecting components, made from a variety of materials that allow an implant system to be built from the occiput to the upper thoracic spine to fit the patient's anatomical and physiological requirements, as determined by preoperative cross-sectional imaging. Such a spinal assembly consists of a combination of bone anchors via screws (i.e., occipital screws, cervical lateral mass screws, cervical pedicle screws, C2 pars screws, C2 translaminar screws, C2 transarticular screws), longitudinal members (e.g., plates, rods, including dual diameter rods, plate/rod combinations), transverse or cross connectors, interconnection mechanisms (e.g., rod-to-rod connectors, offset connectors), and closure mechanisms (e.g., set screws, nuts). Posterior cervical screw systems are rigidly fixed devices that do not contain dynamic features, including but not limited to: non-uniform longitudinal elements or features that allow more motion or flexibility compared to rigid systems.Posterior cervical screw systems are intended to provide immobilization and stabilization of spinal segments in patients as an adjunct to fusion for acute and chronic instabilities of the cervical spine and/or craniocervical junction and/or cervicothoracic junction such as: (1) Traumatic spinal fractures and/or traumatic dislocations; (2) deformities; (3) instabilities; (4) failed previous fusions (
e.g., pseudarthrosis); (5) tumors; (6) inflammatory disorders; (7) spinal degeneration, including neck and/or arm pain of discogenic origin as confirmed by imaging studies (radiographs, CT, MRI); (8) degeneration of the facets with instability; and (9) reconstruction following decompression to treat radiculopathy and/or myelopathy. These systems are also intended to restore the integrity of the spinal column even in the absence of fusion for a limited time period in patients with advanced stage tumors involving the cervical spine in whom life expectancy is of insufficient duration to permit achievement of fusion.(b)
Classification. Class II (special controls). The special controls for posterior cervical screw systems are:(1) The design characteristics of the device, including engineering schematics, must ensure that the geometry and material composition are consistent with the intended use.
(2) Nonclinical performance testing must demonstrate the mechanical function and durability of the implant.
(3) Device components must be demonstrated to be biocompatible.
(4) Validation testing must demonstrate the cleanliness and sterility of, or the ability to clean and sterilize, the device components and device-specific instruments.
(5) Labeling must include the following:
(i) A clear description of the technological features of the device including identification of device materials and the principles of device operation;
(ii) Intended use and indications for use including levels of fixation;
(iii) Device specific warnings, precautions, and contraindications that include the following statements:
(A) “Precaution: Preoperative planning prior to implantation of posterior cervical screw systems should include review of cross-sectional imaging studies (
e.g., CT and/or MRI) to evaluate the patient's cervical anatomy including the transverse foramen, neurologic structures, and the course of the vertebral arteries. If any findings would compromise the placement of these screws, other surgical methods should be considered. In addition, use of intraoperative imaging should be considered to guide and/or verify device placement, as necessary.”(B) “Precaution: Use of posterior cervical pedicle screw fixation at the C3 through C6 spinal levels requires careful consideration and planning beyond that required for lateral mass screws placed at these spinal levels, given the proximity of the vertebral arteries and neurologic structures in relation to the cervical pedicles at these levels.”
(iv) Identification of magnetic resonance (MR) compatibility status;
(v) Cleaning and sterilization instructions for devices and instruments that are provided non-sterile to the end user, and;
(vi) Detailed instructions of each surgical step, including device removal.
