The summary describes a spinal screw system and bone cement, focusing on materials, mechanical properties, and intended use. There is no mention of AI or ML technology in the device description, intended use, or performance studies.
Yes.
The device, which includes fenestrated screws and bone cement, is intended for various medical conditions such as degenerative disc disease, spondylolisthesis, tumors, trauma, and spinal stenosis. It aims to restore the integrity of the spinal column and provide fixation as an adjunct to fusion or independent of fusion for a limited time. These functions directly address health issues and contribute to the treatment or amelioration of disease or injury, thus qualifying it as a therapeutic device.
No
Explanation: The provided text describes a medical device, the CD HORIZON™ Fenestrated Screws and associated bone cements, intended for surgical fixation and restoration of the spinal column as an adjunct to fusion or for treating pathological fractures. Its purpose is therapeutic and structural support, not to diagnose a condition.
No
The device description clearly outlines physical components (screws, bone cement) and mechanical testing, indicating it is a hardware device, not software-only.
Based on the provided text, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostic devices are used to examine specimens taken from the human body (like blood, urine, or tissue) to provide information about a person's health.
- Device Description and Intended Use: The description and intended use clearly state that this device is a surgical implant (screws and bone cement) used for spinal fixation and stabilization. It is directly implanted into the patient's body.
- Lack of Specimen Analysis: There is no mention of analyzing any biological specimens from the patient. The device's function is mechanical support and stabilization within the spine.
Therefore, the CD HORIZON™ Fenestrated Screws and associated bone cements are medical devices, but they do not fit the definition of an In Vitro Diagnostic device.
N/A
Intended Use / Indications for Use
When used without cement, the CD HORIZON™ Fenestrated Screws (with or without SEXTANT™ or LONGITUDE™ instrumentation) are intended for posterior, non-cervical fixation as an adjunct to fusion for the following indications: degenerative disc disease (defined as back pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies), spondylolisthesis, tumor and/or trauma (i.e., fracture or dislocation), spinal stenosis, curvatures (i.e., scoliosis, kyphosis, or lordosis), pseudarthrosis, and/or failed previous fusion.
When used in conjunction with Medtronic HV-R™ Fenestrated Screw Bone Cement or Kyphon™ XPEDE™ Bone Cement, the CD HORIZON™ Fenestrated Screws are 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 thoracic and lumbar spine in whom life expectancy is of insufficient duration to permit achievement of fusion. CD HORIZON™ Fenestrated Screws augmented with either Medtronic HV-R™ Fenestrated Screw Bone Cement or Kyphon™ XPEDE™ Bone Cement are for use at spinal levels where the structural integrity of the spine is not severely compromised.
KYPHON™ Xpede™ Bone Cement is indicated for the treatment of pathological fractures of the vertebral body due to osteoporosis, cancer, or benign lesions a cementoplasty (i.e. kyphoplasty or vertebroplasty) procedure. It is also indicated for the fixation of pathological fractures of the sacral vertebral body or ala using sacral vertebroplasty or sacroplasty. Cancer includes multiple myeloma and metastatic lesions, including those arising from breast or lung cancer, or lymphoma. Benign lesions include hemangioma and giant cell tumor. Pathological fracture may include a symptomatic microfracture (as documented by appropriate imaging and/or presence of a lytic lesion) without obvious loss of vertebral body height.

Kyphon Xpede™ Bone Cement is provided sterile in two components: 20 grams of powder and nine grams of liquid. The powder contains methylmethacrylate-styrene co-polymer, barium sulfate as a radiopacifier, and di-benzoyl peroxide as an initiator. This liquid contains methylmethacrylate monomer, N, N dimethyl-p-toluidine as a promoter and hydroquinone as a stabilizer. The powder and liquid components are mixed, in the provided liquid-to-powder proportions, into a homogenous paste, to initiate the polymerization reaction of monomer into polymer. Medtronic HV-RTM Fenestrated Screw Cement is self-curing PMMA based (high viscosity, radiopaque) bone cement. Medtronic HV-RTM Fenestrated Screw Cement is provided sterile in two components: 20 grams of powder and nine grams of liquid. The powder contains methylmethacrylate-styrene co-polymer. barium sulfate as a radiopacifier, and di-benzoyl peroxide as an initiator. This liquid contains methylmethacrylate monomer, N, N dimethyl-p-toluidine as a promoter and hydroquinone as a stabilizer. The powder and liquid components are mixed, in the provided liquid-to-powder proportions, into a homogenous paste, to initiate the polymerization reaction of monomer into polymer.
The CD HORIZON™ Fenestrated Screw Set consists of a variety of cannulated multi-axial screws (MAS) with fenestrations offered in diameters ranging from 4.5mm to 10.5mm, with lengths ranging from 30-100mm based on CD HORIZON™ LEGACY™ and CD HORIZON™ SOLERA™ implants contained in the CD HORIZON™ Spinal System. The CD HORIZON™ Fenestrated Screws are specifically designed to connect to 4.75mm, 5.5mm, and 6.0mm diameter rods and associated connecting components contained within the CD HORIZON™ Spinal System. The screws contain six fenestrations near the distal tip of the screw which provides a controlled means to deliver a small amount of polymethylmethacrylate (PMMA) bone cement into a targeted vertebral body. These implants may also serve as traditional pedicle screws when used without bone cement. These screws are provided non-sterile.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Biocompatibility
Identical to the primary predicate screws, the CD HORIZONTM Fenestrated Screws are provided non-sterile form. They are manufactured from medical grade titanium alloy (in accordance with ASTM F136), medical grade titanium (in accordance with ASTM F67) and medical grade cobalt-chromium-molybdenum alloy (in accordance with ASTM F1537).
The subject XpedeTM Bone Cement is identical to the predicate XpedeTM Bone Cement. The subject cement utilizes equivalent implant materials, sterilization methods and bacterial endotoxin testing applying the same 20 EU/ml pyrogen limit specifications utilizing the gel clot test method as the predicate Kyphon XpedeTM Bone Cement (K102397).
The materials used in the implants and instruments have a long clinical history of safe and effective use in similar commercially available medical devices. Therefore, no additional biocompatibility testing is required.
Mechanical Testing
In accordance with, Guidance for Industry and FDA Staff - Spinal System 510(k)'s", Medtronic has evaluated the subject devices to demonstrate substantial equivalence to the predicate devices. Axial Pull Out Testing in accordance with ASTM F543-07 was performed and compared CD HORIZONTM Fenestrated Screws augmented with the subject Kyphon XepedeTM Bone Cement and the Medtronic HV-RTM Fenestrated Screw Cement. Test results demonstrated the pull-out strength of the screws were equivalent when using Kyphon XpedeTM Bone Cement or Medtronic HV-RTM Fenestrated Screw Cement. Additionally, a flow rate analysis was performed to compare Kyphon XpedeTM Bone Cement to the Medtronic HV-RTM Fenestrated Screw Cement with respect to injection and flow characteristics of the two cements. The cements were evaluated using fluoroscopic imaging. Testing found the flow rates of the subject and predicate cements to be substantially equivalent.

| Bone Cement cleared by the FDA in K102397 (SE 02/28/11). The | |
| predicate cement is intended to be used in patients diagnosed with | |
| pathological fractures in the vertebral body caused by conditions such as | |
| osteoporosis and cancer. The subject cement is also intended to be used in | |
| patients with metastatic cancer. Pathological fractures reflect one means in | |
| which spinal instability occurs and therefore in both instances the | |
| predicate and subject cement are intended to treat spinal instability. The | |
| only differences between the subject and predicate cement are the method | |
| in which the cement is delivered and that the subject cement is limited to | |
| patients with advanced stage tumors involving the thoracic and lumbar | |
| spine in whom life expectancy is of insufficient duration to permit | |
| achievement of fusion. |
- No changes or additions have been made to the fenestrated screws which
comprise the CD HORIZONTM Fenestrated Screw Set cleared previously
in K152604 for the same indications when used in conjunction with
cement augmentation. They are identical in all aspects with respect to
indications, design, size, intended use, cannulation, fundamental scientific
technology, and materials. |
| Performance Data | Biocompatibility |
| | Identical to the primary predicate screws, the CD HORIZONTM Fenestrated
Screws are provided non-sterile form. They are manufactured from medical grade
titanium alloy (in accordance with ASTM F136), medical grade titanium (in
accordance with ASTM F67) and medical grade cobalt-chromium-molybdenum
alloy (in accordance with ASTM F1537). |
| | The subject XpedeTM Bone Cement is identical to the predicate XpedeTM Bone
Cement. The subject cement utilizes equivalent implant materials, sterilization
methods and bacterial endotoxin testing applying the same 20 EU/ml pyrogen
limit specifications utilizing the gel clot test method as the predicate Kyphon

equivalence to the predicate devices. Axial Pull Out Testing in accordance with
ASTM F543-07 was performed and compared CD HORIZONTM Fenestrated
Screws augmented with the subject Kyphon XepedeTM Bone Cement and the
Medtronic HV-RTM Fenestrated Screw Cement. Test results demonstrated the pull-
out strength of the screws were equivalent when using Kyphon XpedeTM Bone
Cement or Medtronic HV-RTM Fenestrated Screw Cement.
Additionally, a flow rate analysis was performed to compare Kyphon XpedeTM
Bone Cement to the Medtronic HV-RTM Fenestrated Screw Cement with respect to
injection and flow characteristics of the two cements. The cements were evaluated
using fluoroscopic imaging. Testing found the flow rates of the subject and
predicate cements to be substantially equivalent. |
| Conclusion | Based upon the test results and additional supporting documentation provided in
the pre-market notification, the subject Kyphon XpedeTM Bone Cement is |
| | substantially equivalent to the Kyphon® Xpede Bone Cement (K102397, SE
