Intended Use

The ZSFab Cervical Interbody System is intended for anterior interbody fusion in skeletally mature patients who have had at least six weeks of non-operative treatment. The ZSFab Cervical Interbody System is indicated to treat cervical disc degeneration and/or cervical spinal instability, as confirmed by imaging studies (radiographs, CT, MRI), that results in radiculopathy, myelopathy, and/or pain at multiple contiguous levels from C2-T1. The ZSFab Cervical Interbody System is designed for use with autogenous and/or allogeneic bone graft comprised of cancellous and/or corticocancellous bone and/or demineralized allograft bone with bone marrow aspirate to facilitate fusion and to be used with supplemental fixation cleared for use in the cervical spine. Implants having a lordotic angulation >10° are required to be used with an anterior cervical plate as the form of supplemental fixation.

Device Story

ZSFab Cervical Interbody System consists of additively manufactured titanium alloy implants for cervical spinal fusion. Implants feature lattice structures with elliptical pores (500-1390μm) and a central bone graft window. Used by surgeons in clinical settings to provide spinal stabilization; packed with autogenous/allogeneic bone graft. Requires supplemental fixation (e.g., anterior cervical plate) for lordotic angles >10°. Device facilitates fusion in patients with degenerative disc disease or instability; provides structural support to the intervertebral space.

Clinical Evidence

Bench testing only. Mechanical testing (static/dynamic axial compression, torsion per ASTM F2077; subsidence per ASTM F2267; expulsion) from original clearance was relied upon. Engineering rationale provided for additional sizes. Sterilization validated per AAMI ST79.

Technological Characteristics

Material: Ti-6Al-4V ELI titanium alloy (ASTM F3001). Design: Additively manufactured lattice structure with bone graft window. Dimensions: Variable heights, lengths, widths, and lordotic angles. Sterilization: Validated per AAMI ST79.

Indications for Use

Indicated for skeletally mature patients with cervical disc degeneration and/or cervical spinal instability (confirmed by imaging) resulting in radiculopathy, myelopathy, and/or pain at C2-T1 levels, following at least six weeks of failed non-operative treatment.

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.

The implants are designed with lattice structures to provide surgical stabilization of the spine. The lattices have near-elliptical pores with minor axis length of 500-920μm and maior axis length of 810-1390μm. Each interbody has a bone graft window that can be packed with bone graft material. The implants are available in a variety of height, length, width and lordotic angulation combinations to accommodate the patient specific anatomy and clinical circumstances. | | Indications for Use: | The ZSFab Cervical Interbody System is intended for anterior interbody fusion in skeletally mature patients who have had at least six weeks of non-operative treatment. The ZSFab Cervical Interbody System is indicated to treat cervical disc degeneration and/or cervical spinal instability, as confirmed by imaging studies (radiographs, CT, MRI), that results in radiculopathy, myelopathy, and/or pain at multiple contiguous levels from C2-T1.

The testing included static and dynamic axial compression and static and dynamic torsion according to ASTM F2077, subsidence according to ASTM F2267 and expulsion. An engineering rationale was used to demonstrate that the additional cervical interbody sizes did not introduce a new worst case. Sterilization validations were successfully performed to meet AAMI ST79 parameters. | | Technological Characteristics: | The ZSFab Cervical Interbody System possesses the same technological characteristics as one or more of the predicate devices. These include: intended use (as described above) basic design (additively manufactured structure), material (titanium alloy) and sizes (dimensions are comparable to those offered by the predicate systems)The ZSFab Cervical Interbody System is the same as previously cleared devices. | | Conclusion: | The ZSFab Cervical Interbody System possesses the same intended use and technological characteristics as the predicate devices. Therefore the ZSFab Cervical Interbody System is substantially equivalent for its intended use. | {4}------------------------------------------------
