• K Number: K990603
• Device Name: MODIFICATION OF THE ZPLATE-ATL ANTERIOR FIXATION SYSTEM
• Manufacturer: DANEK MEDICAL, INC.
• Date Cleared: 1999-03-10 ( 15 days)
• Product Code: KWQ KWO
• Regulation Number: 888.3060

Intended Use

The ZPLATE-ATL™ Anterior Fixation System is intended for screw/bolt fixation/ attachment to the anterolateral intervertebral bodies from T1 to L5 only. This system is to be used only on one side and placed in such a manner as to be as far away from blood vessels such as the aorta and nerve roots as possible. When properly used, this system will provide temporary stabilization until a solid spinal fusion develops. Specific indications include: 1. Degenerative disc disease (as defined by back pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies). 2. Pseudoarthrosis. 3. Spondylolysis. 4. Spondylolisthesis. 5. Fracture. 6. Neoplastic disease. 7. Unsuccessful previous fusion surgery. 8. Lordotic deformities of the spine. 9. Idiopathic thoracolumbar or lumbar scoliosis 10. Deformity (i.e., scoliosis, lordosis, and/or kyphosis) associated with deficient posterior elements such as that resulting from laminectomy, spina bifida, or myelomenigocele. 11. Neuromuscular deformity (i.e., scoliosis, lordosis, and / or kyphosis) associated with pelvic obliquity. Warning: This device is not approved for screw attachment to the posterior elements (pedicle) of the cervical, thoracic, or lumbar spine.

Device Description

The ZPLATE-ATL™ Anterior Spinal Fixation System consists of a variety of shapes and sizes of plates, bolts, screws and nuts, as well as ancillary products and instrument sets. The components can be locked into a variety of configurations, with each construct tailor-made for the individual case.

AI/ML (Artificial Intelligence / Machine Learning)

No
The provided text describes a mechanical spinal fixation system and its intended use and components. There is no mention of any software, algorithms, or data processing that would indicate the presence of AI or ML.

Therapeutic

Yes
The device is described as an Anterior Fixation System intended for screw/bolt fixation to intervertebral bodies. Its purpose is to provide temporary stabilization until spinal fusion develops for various medical conditions like degenerative disc disease, fractures, and deformities, which indicates a therapeutic intent.

Diagnostic

No

The device description clearly states it is a "fixation system" consisting of "plates, bolts, screws and nuts," intended for "temporary stabilization until a solid spinal fusion develops." This indicates a therapeutic or reconstructive function, not a diagnostic one.

SaMD (Software as a Medical Device)

No

The device description explicitly states that the system consists of plates, bolts, screws, nuts, ancillary products, and instrument sets, which are all physical hardware components.

IVD (In Vitro Diagnostic)

Based on the provided information, 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, or tissue) to provide information about a person's health.
• Device Description and Intended Use: The ZPLATE-ATL™ Anterior Fixation System is a surgical implant designed to provide temporary stabilization to the spine. It is physically implanted into the body to fix bones together.
• Lack of Diagnostic Function: The description and intended use clearly state its purpose is mechanical fixation and stabilization, not the analysis of biological samples for diagnostic purposes.

Therefore, the ZPLATE-ATL™ Anterior Fixation System falls under the category of a surgical implant or orthopedic device, not an In Vitro Diagnostic.

Regulation Number and Section

§ 888.3060 Spinal intervertebral body fixation orthosis.

(a)
Identification. A spinal intervertebral body fixation orthosis is a device intended to be implanted made of titanium. It consists of various vertebral plates that are punched into each of a series of vertebral bodies. An eye-type screw is inserted in a hole in the center of each of the plates. A braided cable is threaded through each eye-type screw. The cable is tightened with a tension device and it is fastened or crimped at each eye-type screw. The device is used to apply force to a series of vertebrae to correct “sway back,” scoliosis (lateral curvature of the spine), or other conditions.(b)
Classification. Class II.
