Intended Use

The PLIF STS, TLIF STS and OLIF STS (Spine Truss System) are in skeletally mature patients with Degenerative Disc Disease (DDD) at one or two contiguous levels from L2-S1. DDD is defined as discogenic back pain with degeneration of the disc confirmed by patient history and radiographic studies. Patients should have received 6 months of non-operative treatment prior to treatment with the device must be used with supplemental fixation and must be used with autograft bone. These DDD patients may also have up to Grade I spondylolisthesis or retrolisthesis at the involved level(s).

Device Story

Spine Truss System (STS) consists of titanium alloy (Ti6Al4V) intervertebral body fusion implants; open architecture truss design provides mechanical support while facilitating bone growth/fusion. Implants available in multiple sizes to accommodate patient anatomy. Used by surgeons in spinal fusion procedures to treat DDD; requires supplemental fixation and autograft bone. Device provides structural stability to the intervertebral space during the biological fusion process.

Clinical Evidence

Bench testing only. Mechanical testing included static axial compression, static compression shear, dynamic axial compression, and dynamic compressive shear per ASTM F2077, plus subsidence testing per ASTM F2267-04 and expulsion testing.

Technological Characteristics

Material: Ti6Al4V alloy. Design: Open architecture truss. Mechanical testing standards: ASTM F2077 (static/dynamic axial compression and compression shear), ASTM F2267-04 (subsidence).

Indications for Use

Indicated for skeletally mature patients with Degenerative Disc Disease (DDD) at one or two contiguous levels from L2-S1, including those with up to Grade I spondylolisthesis or retrolisthesis. Requires 6 months of failed non-operative treatment. Must be used with supplemental fixation and autograft bone.

Regulatory Classification

Identification

An intervertebral body fusion device is an implanted single or multiple component spinal device made from a variety of materials, including titanium and polymers. The device is inserted into the intervertebral body space of the cervical or lumbosacral spine, and is intended for intervertebral body fusion.

Special Controls

*Classification.* (1) Class II (special controls) for intervertebral body fusion devices that contain bone grafting material. The special control is the FDA guidance document entitled “Class II Special Controls Guidance Document: Intervertebral Body Fusion Device.” See § 888.1(e) for the availability of this guidance document.(2) Class III (premarket approval) for intervertebral body fusion devices that include any therapeutic biologic (e.g., bone morphogenic protein). Intervertebral body fusion devices that contain any therapeutic biologic require premarket approval. (c) *Date premarket approval application (PMA) or notice of product development protocol (PDP) is required.* Devices described in paragraph (b)(2) of this section shall have an approved PMA or a declared completed PDP in effect before being placed in commercial distribution.

Predicate Devices

Dear Dr. Jansen:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food. Drug. and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls.

## Indications for Use:

The PLIF STS, TLIF STS and OLIF STS (Spine Truss System) are indicated for use in skeletally mature patients with Degenerative Disc Disease (DDD) at one or two contiguous levels from 12-S1. DDD is defined as discogenic back pain with degeneration of the disc confirmed by patient history and radiographic studies. Patients should have received 6 months of non-operative treatment prior to treatment with the devices. The device must be used with supplemental fixation and must be used with autograft bone. These DDD patients may also have up to Grade I spondylolisthesis or retrolisthesis at the involved level(s).

## Device Description:

The 4WEB PLIF STS, TLIF STS and OLIF STS (Spine Truss System) consists of a series of titanium implants that are designed to provide mechanical support to the spine while biologic fusion occurs. The device is an "open architecture" design consisting of trusses mathematically designed to provide maximum support with the greatest amount of open space throughout the implant for bone growth and fusion. The implant is made from Ti6Al4V alloy. The device is available in multiple sizes to accommodate varied patient's anatomy.

{4}------------------------------------------------

## Predicate Device(s):

The 4WEB PLIF STS, TLIF STS and OLIF STS (Spine Truss System) is substantially equivalent to the Primary Predicate, the 4WEB ALIF STS (K112316). Additional predicates include the K2M Aleutian (K133614) and the Orthofix Forza (K103111).

## Performance Standards:

Preclinical testing performed on the 4WEB PLIF STS, TLIF STS and OLIF STS (Spine Truss System) included static axial compression, static compression shear, dynamic axial compression, and dynamic compressive shear mechanical testing per ASTM F2077. The other mechanical test included subsidence per ASTM F2267-04 as well as expulsion testing to demonstrate substantial equivalence.

# Technological Characteristics

The 4Web PLIF STS, TLIF STS and OLIF STS (Spine Truss System) is exactly the same as the primary predicate device in Indications for Use, materials, manufacturing and design. It is substantially equivalent to the additional predicate devices in sizes, surgical approaches risks.

# Conclusion:

4WEB, Inc. concludes that the PLIF STS, TLIF STS and OLIF STS (Spine Truss System) devices are substantially equivalent to the predicate devices and raise no new questions of safety or effectiveness.
