Intended Use

The Wenzel Spine VariLift Cervical Interbody Fusion System is indicated for use in skeletally mature patients with degenerative disc disease (DDD) of the cervical spine with accompanying radicular symptoms at one disc level. DDD is defined as discogenic pain with degeneration of the disc confirmed by patient history and radiographic studies. These DDD patients may have up to Grade 1 spondylolisthesis or retrolisthesis at the involved level(s). The Wenzel Spine VariLift Cervical Interbody Fusion System is used to facilitate intervertebral body fusion in the cervical spine and is placed in a unilateral or a bilateral fashion via an anterior approach at the C3 to C7 disc levels using autograft bone. The Wenzel Spine VariLift Cervical Interbody Fusion System is to be used with supplemental fixation. Patients should have at least six (6) weeks of non-operative treatment prior to treatment with an intervertebral fusion device.

Device Story

VariLift Cervical Interbody Fusion System is a self-tapping, expandable, cylindrical-ovoid interbody fusion device featuring an interior sliding wedge. Constructed from Titanium-6Al-4V ELI alloy, the device is grooved and fluted with large fenestrations to facilitate bony contact with vertebral endplates. It is implanted via an anterior approach in a unilateral or bilateral fashion at C3-C7 levels to facilitate fusion. The device is intended for use in conjunction with autograft bone and supplemental fixation in skeletally mature patients with degenerative disc disease. It is used by surgeons in a clinical/surgical setting to stabilize the spine and promote fusion, potentially reducing radicular symptoms associated with disc degeneration.

Clinical Evidence

No clinical data provided. Substantial equivalence is supported by non-clinical bench testing, including static and dynamic compression, shear, and torsion testing per ASTM F2077-03, and expulsion testing per ASTM Draft Standard F-04.25.02.02.

Technological Characteristics

Material: Titanium-6Al-4V ELI alloy (ASTM F136). Design: Cylindrical-ovoid, self-tapping, expandable with interior sliding wedge. Features: Grooved, fluted, large fenestrations for bony contact. Connectivity: None (mechanical implant). Sterilization: Supplied sterile.

Indications for Use

Indicated for skeletally mature patients with cervical degenerative disc disease (DDD) and radicular symptoms at one level (C3-C7). Includes patients with up to Grade 1 spondylolisthesis or retrolisthesis. Requires 6 weeks of prior non-operative treatment. Must be used with autograft and supplemental fixation.

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.

#### CONCLUSIONS

The subject and predicate devices share the same intended use, implant design and material of manufacture. The non-clinical test results demonstrate that any minor differences do not impact device performance as compared to the predicates. The nonclinical and clinical test results demonstrate that the VariLift Cervical Interbody Fusion System is substantially equivalent to the predicate devices and support the use of VariLift-C with supplemental fixation.
