Indications for Use
The Camber Spine Technologies ENZA Zero-Profile Anterior Interbody Fusion is indicated for use with autogenous bone graft in patients with degenerative disc disease (DDD) at one or two contiguous levels from L2 to S1. These DDD patients may also have up to Grade I Spondylolisthesis or retrolisthesis at the involved levels. DDD is defined as discogenic back pain with degeneration of the disc confirmed by history and radiographic studies. These patients should be skeletally mature and have had six months of non-operative treatment. Patients with previous non-fusion spinal surgery at the treated level may be treated. These implants may be implanted via a laparoscopic or an open anterior approach. The Camber Spine Technologies ENZA Zero-Profile Anterior Interbody Fusion is intended to be used with additional FDA-cleared supplementary fixation systems. The Camber Spine Technologies ENZA Zero-Profile Anterior Interbody Fusion system must be used with bone grafting material (autograft only).
Device Story
Interbody fusion device; hollow chamber for autogenous bone graft; superior/inferior surfaces feature teeth for stability; includes manually deployed built-in fixation mechanism. Implanted via laparoscopic or open anterior approach by surgeon. Used to facilitate spinal fusion in DDD patients. Output is physical stabilization of vertebral bodies. Benefits include fusion support and reduced movement at treated levels.
Clinical Evidence
Bench testing only. Testing included static compression, static compression-shear, dynamic compression, dynamic torsion, dynamic compression-shear, expulsion, and subsidence per ASTM F2077-14 and F2267-04. Wear testing and blade deployment testing were also conducted. Results demonstrate acceptance criteria defined by predicate devices were met.
Technological Characteristics
Interbody fusion device with hollow chamber and integrated manual blade fixation mechanism. Surfaces feature teeth for stability. Testing performed per ASTM F2077-14 and F2267-04. No software or electronic components.
Indications for Use
Indicated for skeletally mature patients with degenerative disc disease (DDD) at one or two contiguous levels from L2 to S1, including those with up to Grade I Spondylolisthesis or retrolisthesis. Requires six months of failed non-operative treatment. For use with autogenous bone graft and supplementary 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.
